Neurorehabilitation; What are some of the things we know?

Saebo Techknowlogy

By Shannon L. Scott OTR/L

There is alot we still don’t know about what constitutes “best practice” when it comes to neurorehabilitation and how to affect optimal recovery and outcomes, but there are some things that we do have a better understanding of. Let’s take stroke recovery and rehabilitation as an example, specifically upper extremity (UE) recovery, since it is reported that at least 50% of individuals who suffer a stroke have UE involvement and impairments (though the numbers vary depending on which study you are reading).

Following a stroke, we do know that muscle weakness and imbalance, abnormal tone/spasticity, impaired sensation, and pain are primary UE impairments (though pain is more secondary than primary). We also know that muscle imbalance and abnormal tone can lead to soft tissue shortening and joint contractures which results in loss of range of motion. We know that all of these contribute to an…

[BROCHURE] Saebo ArmTraining Program

Download Broshure

“The SaeboFlex® is just a huge, unbelievable blessing to me! Immediately, after 19 years post stroke, I could squeeze and release with my right hand! … Because of the SaeboFlex I am now able to do things that I couldn’t do before. I am able to put on deodorant, wash in the shower with both hands, hold a hymn book, pick up objects off the floor, eat a banana with my affected side, and open mail. I encourage any and every stroke survivor to take this training.”

[WEB SITE] Has the brain-zap backlash begun?

…Stimulating the brain with electricity improves working memory, mental maths,focused attention, creativity and could help treat depression. You can even buy DIY kits online. That’s the good news. The bad news is that the most recent investigation has found it has almost no measurable effect on the brain.

It’s a conclusion that is likely to be controversial. Over the past decade, thousands of studies have reported a beneficial effect of transcranial direct current stimulation (tDCS) on the brain, as well as on behaviour and cognition – so much so that it has become something of a hot topic in neuroscience…

[ARTICLE] Mechanical stimulation of the foot sole in a supine position for ground reaction force simulation – Full Text HTML

Abstract (provisional)

Background: To promote early rehabilitation of walking, gait training can start even when patients are on bed rest. Supine stepping in the early phase after injury is proposed to maximise the beneficial effects of gait restoration. In this training paradigm, mechanical loading on the sole of the foot is required to mimic the ground reaction forces that occur during overground walking. A pneumatic shoe platform was developed to produce adjustable forces on the heel and the forefoot with an adaptable timing. This study aimed to investigate the stimulation parameters of the shoe platform to generate walking-like loading on the foot sole, while avoiding strong reflexes.

Methods: This study evaluated this platform in ten able-bodied subjects in a supine position. The platform firstly produced single-pulse stimulation on the heel or on the forefoot to determine suitable stimulation parameters, then it produced cyclic stimulation on the heel and the forefoot to simulate the ground reaction forces that occur at different walking speeds. The ankle angle and electromyography (EMG) in the tibialis anterior (TA) and soleus (SOL) muscles were recorded. User feedback was collected.

Results: When the forefoot or/and the heel were stimulated, reflexes were observed in the lower leg muscles, and the amplitude increased with force. Single-pulse stimulation showed that a fast-rising force significantly increased the reflex amplitudes, with the possibility of inducing ankle perturbation. Therefore a slow-rising force pattern was adopted during cyclic stimulation for walking. The supine subjects perceived loading sensation on the foot sole which was felt to be similar to the ground reaction forces during upright walking. The EMG generally increased with force amplitude, but no reflex-induced ankle perturbations were observed. The mean change in the ankle joint induced by the stimulation was about 1[degree sign].

Conclusions: The rate of force increase should be carefully adjusted for simulation of walking-like loading on the foot sole. It is concluded that the dynamic shoe platform provides adjustable mechanical stimulation on the heel and the forefoot in a supine position and has technical potential for simulation of ground reaction forces that occur during walking.

[WEB SITE] Depression & The Internet: Welcome To Your Temporary Support Group

Mental health is a sometimes a taboo topic among most people in the “outside” world. Thankfully, we have the Internet to discuss how we are feeling. If you’re like me, sometimes it’s easier to stay in bed, unshaven, unshowered, barely-dressed, and it’s very difficult to find someone to talk to while in that state. A simple post on an online community may garner a response that motivates you just enough to get up and get out.

It’s okay if you’re hurting, but you don’t have to keep it to yourself. It is important to talk about it. It’s more important to talk with someone face-to-face, but if you need the Internet to get you talking, then you go, Glen Coco.

13 Natural Remedies for Depression

I’ve been on depression medication since I was 9 years old, well technically it was prescribed for anxiety in the beginning, but soon I was treated for both. In 3rd grade I was able to say, rather clumsily, “I am taking chill pills because there is an imbalance of serotonin in my brain.”

Depression is like a worn-out unwanted companion that constantly clings to me, a burden, yes, but very familiar. Over the years I have realized that there are a lot of things that I can do that don’t require prescription medications to help keep my mood fluctuations under control. They take time and effort (there is no quick and easy fix!), but its well worth it in my mind. I still have not weaned myself off of my medications entirely, but it is a goal that I someday hope to achieve and one that I constantly strive for.

[WHITE PAPER] tDCS clinical research – highlights: Depression – Full Text PDF

Is transcranial current stimulation (tCS, including direct current, tDCS, alternating current, tACS, or random noise stimulation tRNS) effective for the treatment of depression?

Under what conditions? With what montages? We focus here on a review of the recent literature on this topic. We have relied on Google Scholar and also PubMed to carry out the search, including the terms of tDCS, tACS, tRNS as well as Depression (from March 2012 and till Sep 2013).

As you can read below, there quite a few encouraging results in this area, and study group sizes (the famous N) are moderately large. We try to indicate group size and the use of a sham-controlled, double-blind experimental technique. Most studies are careful about these crucial aspects. In addition, it is worth mentioning that there continues to be a lack of bad news from the safety point of view. This seems to be a common pattern of tDCS research (or tCS, in fact). I will discuss this further in a future post on an update on tCS Safety.

The typical target for treatment is anodal on the left DLPFC (F3 in the 10-20 EEG system) with the cathode over the contralateral orbit or, sometimes, over the right DLPFC. As in prior posts, in what follows we concentrate on relevant, study-oriented papers with patients, and leave reviews to the end. In order to make the reading lighter, we have edited the abstracts a bit (please click on the title link if you are interested in the paper)… Full Text PDF

[WEB SITE] Ketamine therapy: New, innovative treatment for depression in the Valley

SCOTTSDALE, AZ – The Valley has one of the first Ketamine clinics in the country — with the newest innovation fighting depression to help you or your family.

Colorful History

Ketamine is more commonly known as a horse tranquilizer. In the ’90s, crooks stole Ketamine out of veterinarian clinics to sell on the street as ‘Special K.’ It was a popular rave drug.

But, Ketamine really got its start during the Vietnam War. It was used as an anesthetic. It’s also used in emergency rooms across the country.

Today, it’s the hottest new method for treating clinical depression.

Treating Depression

The clinic is called, Depression Recovery Centers and it is located in Scottsdale. There, patients receive small doses of the drug intravenously while being closely monitored at the clinic. “We are seeing incredible results,” said Dr. Ellen Diamond, a clinical psychologist at the clinic. “I have seen person after person come through here and their life has been changed.”

Ger Gaines is the clinic’s owner. He made his first fortune as one of the founders of Sprint PCS. Now, he’s taking on clinical depression. “Depression is very common. About 10 percent of the population has depression at any given time,” he said.

But for Gaines, it is more than just a business venture. “I suffer from bipolar disorder,” he said, “But probably more motivating, I have close relatives that also suffer from depression. And just being able to do something that can change their lives is important to me.”

Ketamine treatment for depression was found accidently. It was being used for pain relief when many of the patients noticed they weren’t depressed anymore. “We are more directly targeting the structures in the brain that control emotions,” Diamond said.

Gaines uses “dead leaves on a tree” as an analogy. “What the Ketamine does is take that unhealthy looking tree in winter and grow it back to a tree in summer in just an hour’s time.”…

[ARTICLE] Rehabilitation exercise assessment using inertial sensors: a cross-sectional analytical study

Abstract (provisional)

Background: Accurate assessments of adherence and exercise performance are required in order to ensure that patients adhere to and perform their rehabilitation exercises correctly within the home environment. Inertial sensors have previously been advocated as a means of achieving these requirements, by using them as an input to an exercise biofeedback system. This research sought to investigate whether inertial sensors, and in particular a single sensor, can accurately classify exercise performance in patients performing lower limb exercises for rehabilitation purposes.

Methods: Fifty-eight participants (19 male, 39 female, age: 53.9 +/- 8.5 years, height: 1.69 +/- 0.08 m, weight: 74.3 +/- 13.0 kg) performed ten repetitions of seven lower limb exercises (hip abduction, hip flexion, hip extension, knee extension, heel slide, straight leg raise, and inner range quadriceps). Three inertial sensor units, secured to the thigh, shin and foot of the leg being exercised, were used to acquire data during each exercise. Machine learning classification methods were applied to quantify the acquired data.

Results: The classification methods achieved relatively high accuracy at distinguishing between correct and incorrect performance of an exercise using three, two, or one sensor while moderate efficacy scores were also achieved by the classifier when attempting to classify the particular error in exercise performance. Results also illustrated that a reduction in the number of inertial sensor units employed has little effect on the overall efficacy results.

Conclusion: The results revealed that it is possible to classify lower limb exercise performance using inertial sensors with satisfactory levels of accuracy and reducing the number of sensors employed does not reduce the accuracy of the method.
