[BLOG POST] Things to Know the Foot Drop Treatment

ROBERTCHASE JUL 31, 2018

Foot drop (now and again called drop foot or dropped foot) is the failure to raise the front of the foot because of shortcoming or loss of motion of the muscles and nerves that lift the foot. Foot drop itself isn’t a sickness; it is a manifestation of a more outstanding issue or restorative condition.

You can perceive foot drop by how it influences your step. Somebody with foot drop may drag their toes along the ground when strolling because they can’t lift the front of their foot with each progression. With a particular end goal to abstain from hauling their toes or stumbling they may lift their knee higher or swing their leg in a full bend. That is called steppage walk and is a way of dealing with stress for foot drop issues.

Reasons for Foot Drop

There is three primary driver of the debilitated nerves or muscles that quick foot drop:

1: Nerve Injury

The peroneal nerve is the nerve that imparts to the muscles that lift the foot. Harm to the peroneal nerve is the most popular reason for foot drop. The nerve wraps from the back of the knee to the front of the shin and sits intently to the surface, making it simple to harm. Harm to the peroneal nerve can be caused by sports wounds, hip or knee substitution medical procedure, a leg cast, labor or notwithstanding folding your legs.

2: Muscle Disorders

A condition that makes the muscles gradually debilitate or break down can likewise cause foot drop. This clutter may incorporate muscular dystrophy, amyotrophic sidelong sclerosis (Lou Gehrig’s malady) and polio.

3: Brain or Spinal Disorders

Neurological conditions can likewise cause foot drop. States may incorporate stroke, multiple sclerosis (MS), cerebral paralysis and Charcot-Marie-Tooth illness.

How Foot Drop is Treated

Treatment for foot drop requires treating the hidden therapeutic condition that caused it. At times foot drop can be lasting, but numerous individuals can recoup. Various medications can help with foot drop:

1: Surgery

If a squeezed nerve or herniated circle cause your foot drop, then you will probably have a medical procedure to treat it. The medical system may likewise be necessary to repair muscles or ligaments if they were explicitly harmed and are causing foot drop. In severe or long haul cases, you may have the medical procedure to intertwine your ankle and foot bones and enhance your stride.

2: Functional Electrical Stimulation

A little device can be worn or carefully embedded just beneath the knee that will empower the typical capacity of the nerve, making the muscle contract and the foot to lift while at the same time strolling.

3: Braces or Ankle Foot Orthosis (AFO)

Wearing an AFO knee brace that backings the foot in a typical position are a standard treatment for foot drop. The gadget will balance out your foot and ankle and hold the front piece of the foot up when strolling. While generally, specialists have endorsed massive stiff braces that go inside the shoe, the Saebo Step is a lightweight and practical alternative that offers help outside the shoe.

4: Physical Therapy

Treatment to fortify the foot, ankle and lower leg muscles are the essential treatment for foot drop and will by, and large be recommended notwithstanding the treatment alternatives specified previously. Extending and scope of movement activities will likewise help keep stiffness from creating in the rear foot area.

[WEB SITE] Several Types of Foot Drop Treatment

Recuperation relies upon the reason for foot drop and to what extent you’ve had it. Now and again it can be lasting. Rolling out little improvements in your home, for example, expelling mess and utilizing non-slip mats and tangles, can help avoid falls. There are likewise measures you can take to help settle your foot and enhance your strolling capacity.

Medicines for drop foot include:

  • Physiotherapy – to reinforce your foot, ankle and lower leg muscles
  • Wearing an ankle-foot orthosis – to hold your foot in a typical position
  • Electrical nerve incitement – in specific cases it can help lift the foot.
  • Surgery – an activity to combine the ankle or foot bones might be conceivable in extreme or long haul cases

Non-intrusive treatment:

In circumstances where foot drop has caused a significant walk unsettling influence, exercise-based recuperation might be required. Specific practice based recovery for foot drop may incorporate stride preparing that encourages the patient how to walk once more.

In less emotional circumstances, specific activities may essentially be encouraged to encourage the influenced muscles. Active recuperation might be called for in blend with different types of treatments, for example, those demonstrated as follows.

Ankle-foot orthosis:

An ankle-foot orthosis for foot drop is worn on the lower some part of the leg to help manage the ankle and foot. If your GP figures an AFO will enable, they’ll to allude you for an evaluation with an orthopedist. Wearing a snug sock between your skin and the AFO will guarantee solace and help anticipate rubbing. Your footwear ought to be fitted around the orthosis.

Ribbon up shoes or those with Velcro fastenings are prescribed for use with AFOs because they’re anything but trying to alter. Shoes with a removable trim are likewise valuable because they give additional room. High-obeyed shoes ought to be kept away from.

Breaking your orthosis in gradually is essential. Once broken in, wear it however much as could reasonably be expected while strolling because it will enable you to walk all the more proficiently and keep you stable. There exists a wide assortment of orthosis so discovering one that is agreeable and practical gives numerous alternatives.

Electrical nerve incitement:

Now and again, an electrical incitement gadget, like a TENS machine, can be utilized to enhance strolling capacity. It can enable you to walk quicker, with not so much exertion but rather more certainty. Two self-glue anode patches are set on the skin. One is placed near the nerve providing the muscle and the other over the focal point of the muscle.

The trigger produces electrical driving forces that animate the nerves to contract (abbreviate) the influenced muscles. The trigger is activated by a sensor in the shoe and is initiated each time your sole foot area leaves the ground as you walk.

Medical procedure:

The medical process might be an alternative in severe or long haul instances of foot drop that have caused perpetual development misfortune from muscle loss of motion. The technique more often than not includes exchanging a ligament from the more grounded leg muscles to the muscle that ought to pull your ankle upwards. Another sort of medical procedure comprises combining the foot or ankle unresolved issues balance out the ankle.

[ARTICLE] Randomized controlled trial of robot-assisted gait training with dorsiflexion assistance on chronic stroke patients wearing ankle-foot-orthosis – Full Text

Abstract

Background

Robot-assisted ankle-foot-orthosis (AFO) can provide immediate powered ankle assistance in post-stroke gait training. Our research team has developed a novel lightweight portable robot-assisted AFO which is capable of detecting walking intentions using sensor feedback of wearer’s gait pattern. This study aims to investigate the therapeutic effects of robot-assisted gait training with ankle dorsiflexion assistance.

Methods

This was a double-blinded randomized controlled trial. Nineteen chronic stroke patients with motor impairment at ankle participated in 20-session robot-assisted gait training for about five weeks, with 30-min over-ground walking and stair ambulation practices. Robot-assisted AFO either provided active powered ankle assistance during swing phase in Robotic Group (n = 9), or torque impedance at ankle joint as passive AFO in Sham Group (n = 10). Functional assessments were performed before and after the 20-session gait training with 3-month Follow-up. Primary outcome measure was gait independency assessed by Functional Ambulatory Category (FAC). Secondary outcome measures were clinical scores including Fugl-Meyer Assessment (FMA), Modified Ashworth Scale (MAS), Berg Balance Scale (BBS), Timed 10-Meter Walk Test (10MWT), Six-minute Walk Test (SMWT), supplemented by gait analysis. All outcome measures were performed in unassisted gait after patients had taken off the robot-assisted AFO. Repeated-measures analysis of covariance was conducted to test the group differences referenced to clinical scores before training.

Results

After 20-session robot-assisted gait training with ankle dorsiflexion assistance, the active ankle assistance in Robotic Group induced changes in gait pattern with improved gait independency (all patients FAC ≥ 5 post-training and 3-month follow-up), motor recovery, walking speed, and greater confidence in affected side loading response (vertical ground reaction force + 1.49 N/kg, peak braking force + 0.24 N/kg) with heel strike instead of flat foot touch-down at initial contact (foot tilting + 1.91°). Sham Group reported reduction in affected leg range of motion (ankle dorsiflexion − 2.36° and knee flexion − 8.48°) during swing.

Conclusions

Robot-assisted gait training with ankle dorsiflexion assistance could improve gait independency and help stroke patients developing confidence in weight acceptance, but future development of robot-assisted AFO should consider more lightweight and custom-fit design.

Background

Stroke is caused by intracranial haemorrhage or thrombosis, which cuts off arterial supply to brain tissue and usually damages the motor pathway of the central nervous system affecting one side of the body. About half of the stroke survivors cannot walk at stroke onset, but they have 60% chance to regain independent walking after rehabilitation [1]. Reduced descending neural drive to the paretic ankle joint causes muscle weakness and spasticity, often accompanied with drop foot which is characterized by the foot pointing downward and dragging on the ground during walking [23]. To maintain sufficient foot clearance in swing phase, people with dropped foot have to compensate either by hip hiking with exaggerated flexion in hip and knee joints, or circumduction gait with the body leaning on the unaffected side and the leg swinging outward through an arc away from the midline [456]. These inefficient asymmetric gait patterns hinder the walking ability and contribute to slower walking speed [78], increasing risk of falling [910], and greater energy expenditure [11]. Poor mobility results in sedentary lifestyle and limited physical exercise [12], which further deteriorates lower-limb functionality.

Foot drop can be managed using ankle-foot-orthosis (AFO), which is rigid or articulated ankle brace that controls ankle range of motion (ROM). Meta-analysis shows walking in conventional AFO has immediate or short-term beneficial effects on gait pattern and mobility of stroke patients, including an overall increase in ankle dorsiflexion throughout gait cycle, improvements in Functional Ambulatory Category (FAC), walking speed, and stairs-climbing speed [131415]. Recent development in robot-assisted AFO demonstrates power assistance at ankle joint can facilitate walking of patients presenting with foot drop, by actively assisting ankle dorsiflexion for foot clearance in swing phase and minimizing occurrence of foot slap at initial contact [161718]. Previous studies only evaluated the immediate effects of stroke patients walking in passive AFO [1415] or robot-assisted AFO [1920], but they were not sure whether any assistive effects could be carried over to unassisted gait after the patients had taken off the devices, i.e. the therapeutic effects.

Neuroscience studies suggest the brain is capable of altering its functions and structures for adapting to internal and external environment; an ability known as neuroplasticity [22122]. Researches show intensive repetitive skill training can enhance neuroplasticity and promote motor relearning of stroke patients [2324], which is achievable utilizing robot-assistance in clinical setting. The Anklebot that was developed in MIT can provide power assistance to stroke patients performing repetitive voluntary ankle sagittal movements in seated position, and a single-arm pilot study reports stroke patients (n = 8) had improved volitional ankle control and spatial-temporal gait parameters after 6-week 18-session training using the Anklebot [25]; 30-min seated skill training at ankle joint can induce plastic changes in cortical excitability in area controlling dorsiflexor [26]. Thus robot-assisted AFO with dorsiflexion assistance can potentially stimulate motor recovery of stroke patients with foot drop problem. Neuroscience studies further show the functional outcome of neuroplasticity is task-specific and dependent on the training nature [2212227]. It implies that in order to improve independent walking ability, stroke patients are expected to practise real over-ground walking instead of seated training. Incorporation of stair ambulation into gait training could facilitate generalization towards activity of daily-living, which requires stroke patients to perform skilled ankle dorsiflexion and plantarflexion when they are negotiating steps. Another characteristics of neuroplasticity is the importance of salient experiences for motor relearning from error correction [22122]. During gait training, powered ankle assistance from a robot-assisted AFO could serve as a source of salient proprioceptive feedback synchronized to gait pattern [28]. The robot can strengthen the experience-driven neuroplasticity by producing this proprioceptive feedback at each successfully triggered ankle power assistance [28]. In summary, researches on experience-driven neuroplasticity suggest stroke patients presenting with foot drop problem can potentially restore some level of independent walking ability through robot-assisted gait training with ankle dorsiflexion assistance on over-ground walking and stair ambulation.

To our knowledge, up to now no randomized controlled trial (RCT) has been carried out to validate the rehabilitation approach of robot-assisted AFO [2930]. The current study aims to evaluate whether gait training with robot-assisted AFO with dorsiflexion assistance can bring greater improvement in independent walking ability than training with passive AFO. In each session, stroke patients were trained in 20-min over-ground walking and 10-min stair ambulation. Assessments on the participating stroke patients focused on functional changes in unassisted gait after they had discontinued to wear the devices, i.e. the therapeutic effects. A meta-analysis study recommends FAC to be the primary outcome measure for clinical trials involving electromechanical gait training [30]. FAC is a reliable measurement of independent walking ability on level ground walking and stair ambulation, which is a good prediction of independent community walking post-stroke [31]. The demonstration of safety and effectiveness of the robot-assisted gait training can have positive impact on post-stroke rehabilitation and can potentially establish a new treatment method for stroke patients presenting with foot drop.[…]

[WEB SITE] Foot Drop: Causes, Prevention and How You can Treat It

What is foot drop & what causes it?

Foot drop is a simple name but its cause and treatment may be less than simple.

If you are unable to lift your foot up at the ankle and it makes walking difficult, you may have something called foot drop. This could be due to weakness in one of the muscles responsible for lifting, or dorsiflexing, your foot. It could also be caused by tightness or spasticity in the calf muscles of your leg that cause your toes to point downward.

The cause of foot drop can be from several different sources – neurological, muscular, a side effect from medication, or from a lack of movement.

People with stroke, multiple sclerosis, acquired brain injury, spinal cord injury, or cerebral palsy have a central neurological reason causing weakness, tightness or spasticity. People with peripheral neurologic disease may also have foot drop. These diagnoses could include neuropathy, injury to the lower spinal cord, nerve damage, or illnesses like Guillain-Barre syndrome.

Those who have a traumatic accident or muscular damage could also suffer from foot drop because of damage from swelling and compression.

Certain medications are known to potentially cause foot drop. Talk to your doctor about your medications.

Foot drop can also occur in people who are in bed for a prolonged amount of time. When lying on your back, gravity pulls down your foot, and can cause weakness and overstretch the muscles and nerves on the front of your lower leg.

Can foot drop be prevented?

If you or your loved one is required to be on bedrest or immobile, you can help to prevent foot drop by using a padded splint, by doing stretching, and by doing active exercises like ankle pumps.

If you have an underlying condition, it may be impossible to fully prevent foot drop from occurring. But often you can improve the flexibility and strength in your leg, or use an orthosis or splint to help maintain your foot in a position that will allow you to walk and move safely.

How can foot drop be treated?

The treatment of foot drop depends on the cause and the symptoms you have. Below are some suggestions on what you can do, but make sure to talk to your doctor, therapist or orthotist about the best treatment options for you.

Keep your foot and ankle flexible:

  • Use a foot splint at night

  • Complete daily stretches. The ProStretch gives a great stretch

Improve the tone in your leg:

  • Use an orthosis that puts your ankle in a slight stretch

Strengthen your leg:

  • Use neuromuscular electrical stimulation

  • Complete exercises against gravity or with resistance like a Theraband

  • Stand on a variety of surfaces like an Airex balance pad or a Bosu ball to challenge your muscles in your legs. Hold onto something sturdy or have someone nearby to help

Improve the safety of your walking and prevent falls:

  • Use an ankle foot orthosis to keep your toes up when walking. Depending on your strength level, you may need a flexible one or a rigid one

  • Walk with an assistive device, like a walker or cane

  • Modify your home to prevent you from tripping or falling – consider removing rugs and floor clutter, sitting on a shower chair instead of standing, and observe your home for other potential hazards

Prevent skin problems with the use of splints and orthotics:

  • Make sure to check your skin after you’ve been wearing it, and more often if you have impaired sensation in your legs, diabetes, or a history of wounds. Use a hand held inspection mirror to help

Keep the rest of yourself of healthy:

  • Consider activities like stationary biking or swimming to complete overall strengthening and conditioning

  • Strengthen your core muscles to improve your overall balance and stability

What are the dangers of not treating foot drop?

The biggest risk of not treating foot drop is tripping and falling. Falls lead to injury and other unnecessary treatments or hospitalizations. In order to clear your toes to avoid falling, you will have to change the way you walk. Over time, this could lead to pain or discomfort in your back or legs. Also, if your ankle loses flexibility and you cannot move it at you may need surgery.

Most importantly, without treatment you will have more difficulty doing the things in life that you enjoy doing. Unfortunately, there may be no cure, but there are things you can do to help improve the quality of your life.

Who should I ask for more information?

If you have already been diagnosed or are concerned about your risk for foot drop, you should speak with your healthcare provider about what you can do to prevent and treat it.

[ARTICLE] Short-term effects of physiotherapy combining repetitive facilitation exercises and orthotic treatment in chronic post-stroke patients – Full Text PDF

Abstract.

[Purpose] This study investigated the short-term effects of a combination therapy consisting of repetitive facilitative exercises and orthotic treatment.

[Subjects and Methods] The subjects were chronic post-stroke patients (n=27; 24 males and 3 females; 59.3 ± 12.4 years old; duration after onset: 35.7 ± 28.9 months) with limited mobility and motor function. Each subject received combination therapy consisting of repetitive facilitative exercises for the hemiplegic lower limb and gait training with an ankle-foot orthosis for 4 weeks. The Fugl-Meyer assessment of the lower extremity, the Stroke Impairment Assessment Set as a measure of motor performance, the Timed Up & Go test, and the 10-m walk test as a measure of functional ambulation were evaluated before and after the combination therapy intervention.

[Results] The findings of the Fugl-Meyer assessment, Stroke Impairment Assessment Set, Timed Up & Go test, and 10-m walk test significantly improved after the intervention. Moreover, the results of the 10-m walk test at a fast speed reached the minimal detectible change threshold (0.13 m/s).

[Conclusion] Short-term physiotherapy combining repetitive facilitative exercises and orthotic treatment may be more effective than the conventional neurofacilitation therapy, to improve the lower-limb motor performance and functional ambulation of chronic post-stroke patients.

 

INTRODUCTION

The mobility of many stroke survivorsislimited, and most identify walking as a top priority for rehabilitation1) . One way to manage ambulatory difficulties is with an ankle-foot orthosis (AFO) or a foot-drop splint, which aims to stabilize the foot and ankle while weight-bearing and lift the toes while stepping1) . In stroke rehabilitation, various approaches, including robotic assistance, strength training, and task-related/virtual reality techniques, have been shown to improve motor function2) . The benefits of a high intensity stroke rehabilitation program are well established, and although no clear guidelines exist regarding the best levels of intensity in practice, the need for its incorporation into a therapy program is widely acknowledged2) . Repetitive facilitative exercises (RFE), which combine a high repetition rate and neurofacilitation, are a recently developed approach to rehabilitation of stroke-related limb impairment2–5) . In the RFE program, therapists use muscle spindle stretching and skin-generated reflexes to assist the patient’s efforts to move an affected joint5) . Previous studies have shown that an RFE program improved lower-limb motor performance (Brunnstrom Recovery Stage, foot tapping, and lower-limb strength) and the 10-m walk test in patients with brain damage3) . An AFO is an assistive device to help stroke patients with hemiplegia walk and stand. A properly prescribed AFO can improve gait performance and control abnormal kinematics arising from coordination deficits6) . Gait training with an AFO has been also reported to improve gait speed and balance in post-stroke patients7, 8) . Therefore, we hypothesized that short-term physiotherapy combining RFE and orthotic treatment would improve both lower-extremity motor performance and functional ambulation. The present study aimed to confirm the efficacy of a combination therapy consisting of RFE for the hemiplegic lower limb and gait training with AFO.

[ARTICLE] A user-centered qualitative study on experiences with ankle-foot orthoses and suggestions for improved design – Full Text

Improving ankle-foot orthosis design can best be done by implementing a user-centered approach.

To provide insight into the ideas of ankle-foot orthosis users with flaccid ankle muscle paresis on the importance of activities and suggestions for an improved ankle-foot orthosis design.

A focus-group discussion with eight ankle-foot orthosis users (57 ± 5 years, 50% female).

Main inclusion criteria were as follows: ⩾18 years, unable to stand on tip-toe and unable to lift toes. Main exclusion criterion was spasticity of lower extremity muscles. Transcribed data were coded according to the International Classification of Functioning, Disability and Health. Thematic analysis with inductive approach was chosen to order and interpret codes.

Ankle-foot orthosis users ranked walking the most important activity followed by sitting down/standing up from a chair. Their opinion was that ankle-foot orthoses facilitate walking and standing. Ankle-foot orthosis users suggested that an improved ankle-foot orthosis design should balance between stability and flexibility.

Current ankle-foot orthoses facilitate walking which was the most important activity according to ankle-foot orthosis users. An improved ankle-foot orthosis design should enable walking and should optimize between stability and flexibility dependent on the activity and the paresis severity.

Experienced users of ankle-foot orthosis agreed that matching ankle-foot orthosis functions to daily-life activities is a trade-off between stability and flexibility. An improved ankle-foot orthosis design should at least enable level walking.

 

People with flaccid ankle muscle paresis generally experience problems during walking due to reduced dorsiflexion strength (needed for clearance and controlled plantarflexion during loading response) and/or plantarflexion strength (needed for push-off).1 To improve functioning, an ankle-foot orthosis (AFO) can be prescribed.2 The function of an AFO determines what it must do.3 For people with flaccid paresis, the main AFO function is to compensate for muscle weakness, while for people with spastic paresis, this function is to re-align the joint.2 Due to these function differences, different AFOs can be used depending on the paresis, and therefore, these paresis types should be evaluated separately.

AFOs prescribed for people with flaccid ankle muscle paresis can improve walking.4 However, using an AFO can also come with disadvantages.4 Dorsal AFOs, for example, limit ankle range of motion (ROM).4 This can hamper activities that require a large ankle ROM such as slope walking.5 Improving AFO design can be done best by implementing a user-driven design process as the factors that are most important to users will be taken into account.6 User-driven design is more and more applied in product design to improve acceptance of an innovation by the user.7 In this case, when an AFO fits the needs of users better, adherence to using AFOs can improve.8,9Especially, a qualitative study design can reveal the most important factors since AFO users are not limited by pre-specified questions as is usually the case in quantitative study designs.10 More specifically, a focus-group discussion allowing users to interact is likely to reveal common issues.11 We found one study that evaluated experiences with AFOs.9 However, as they included people with spastic paresis, findings may not be applicable to people with flaccid paresis.

The aim of this explorative study was to provide insight into the ideas of AFO users with flaccid ankle muscle paresis, on the importance of activities and suggestions for an improved AFO design. Providing insight into the importance of activities requires ranking activities according to importance and exploring experiences with these activities.

Objectives: This study aims to investigate the effect of ankle foot orthosis (AFO) on temporospatial parameters, ankle kinematics, and functional ambulation level in patients with stroke.

Patients and methods: Records of 286 adult patients with stroke assessed in the gait and motion analysis laboratory between April 2005 and January 2013 were reviewed. The data of 28 patients (16 males, 12 females; mean age 43.2±15.9 years; range 20 to 72 years) who were analyzed with and without AFO during the same session were selected for the study. Temporospatial parameters (walking speed, cadence, opposite foot contact, double support time, single support time, step time, and step length) and ankle kinematics (ankle dorsiflexion at initial contact and midswing) were measured using the Vicon 512 motion analysis system. The video and medical records of patients were examined to determine their ambulation level according to Functional Ambulation Category.

Results: Walking speed, cadence, and ankle dorsiflexion at initial contact and midswing were significantly increased while walking with AFO compared to walking barefoot (p<0.05). There were significant reduction in step time and significant increase in step length and opposite foot contact with AFO on the affected side (p<0.05). Single support time reduced significantly with AFO on the unaffected side (p<0.05). Functional Ambulation Category score improved significantly with use of AFO (p<0.05).

Conclusion: The use of AFO has positive effects on gait parameters and functional ambulation in patients with stroke.

[ARTICLE] Functional electrical stimulation during post stroke walk: Latest developments

After stroke some residual gait deficits can remain and are prevalent. Foot drop is one of the common impairment which affects around 20% of stroke survivors. This impairment is caused by a paresis (total or partial) of the muscles involved in ankle dorsiflexion. This muscle weakness makes the ground clearance problematic during the swing phase of gait. This default can be compensated by ankle foot orthosis (AFO) but also by functional electrical stimulation.

This is an ancient technique that has benefited from recent advances in technology: wireless link, implanted stimulation, replacement of the heel switch by an inclinometer (System Walkaid)… The SEF is effective in improving walking parameters including walk speed but despite these recent technological improvements, it does not show that it is a more effective device than ankle foot orthoses in a recent study [1]. An inertial node combining an accelerometer, a gyroscope and a magnetometer placed on one of the two legs, is used to estimate the continuous walking cycle [2]. This can advantageously replace the switch in the heel to improve reliability to determine when to start or end the stimulation and also allow for example to start the stimulation at any time, including before the heel off the ground. Moreover, this inertial node should also estimate a number of walking parameters including the quality of ankle dorsiflexion and walking type (normal walk but also pass an obstacle, turn around or climbing stairs) and thus to propose an adaptive functional electrical stimulation in an intelligent way.

The purpose of the presentation is to provide an update on the latest clinical studies and develop perspectives brought by the use of inertial nodes coupled with a wireless stimulator to integrate decision algorithms.

[ARTICLE] Long-Term Follow-up to a Randomized Controlled Trial Comparing Peroneal Nerve Functional Electrical Stimulation to an Ankle Foot Orthosis for Patients With Chronic Stroke

Abstract

Background. Evidence supports peroneal nerve functional electrical stimulation (FES) as an effective alternative to ankle foot orthoses (AFO) for treatment of foot drop poststroke, but few long-term, randomized controlled comparisons exist.

Objective. Compare changes in gait quality and function between FES and AFOs in individuals with foot drop poststroke over a 12-month period.

Methods. Follow-up analysis of an unblinded randomized controlled trial (ClinicalTrials.gov #NCT01087957) conducted at 30 rehabilitation centers comparing FES to AFOs over 6 months. Subjects continued to wear their randomized device for another 6 months to final 12-month assessments. Subjects used study devices for all home and community ambulation. Multiply imputed intention-to-treat analyses were utilized; primary endpoints were tested for noninferiority and secondary endpoints for superiority. Primary endpoints: 10 Meter Walk Test (10MWT) and device-related serious adverse event rate. Secondary endpoints: 6-Minute Walk Test (6MWT), GaitRite Functional Ambulation Profile, and Modified Emory Functional Ambulation Profile (mEFAP). Results. A total of 495 subjects were randomized, and 384 completed the 12-month follow-up. FES proved noninferior to AFOs for all primary endpoints. Both FES and AFO groups showed statistically and clinically significant improvement for 10MWT compared with initial measurement. No statistically significant between-group differences were found for primary or secondary endpoints. The FES group demonstrated statistically significant improvements for 6MWT and mEFAP Stair-time subscore.

Conclusions. At 12 months, both FES and AFOs continue to demonstrate equivalent gains in gait speed. Results suggest that long-term FES use may lead to additional improvements in walking endurance and functional ambulation; further research is needed to confirm these findings.
