[Abstract] Rehabilitation of activities of daily living in virtual environments with intuitive user interface and force feedback
Purpose: To investigate the feasibility of using a virtual rehabilitation system with intuitive user interface and force feedback to improve the skills in activities of daily living (ADL).
Method: A virtual training system equipped with haptic devices was developed for the rehabilitation of three ADL tasks – door unlocking, water pouring and meat cutting. Twenty subjects with upper limb disabilities, supervised by two occupational therapists, received a four-session training using the system. The task completion time and the amount of water poured into a virtual glass were recorded. The performance of the three tasks in reality was assessed before and after the virtual training. Feedback of the participants was collected with questionnaires after the study.
Results: The completion time of the virtual tasks decreased during the training (p < 0.01) while the percentage of water successfully poured increased (p = 0.051). The score of the Borg scale of perceived exertion was 1.05 (SD = 1.85; 95% CI = 0.18–1.92) and that of the task specific feedback questionnaire was 31 (SD = 4.85; 95% CI = 28.66–33.34). The feedback of the therapists suggested a positive rehabilitation effect. The participants had positive perception towards the system.
Conclusions: The system can potentially be used as a tool to complement conventional rehabilitation approaches of ADL.
- Implications for rehabilitation
Rehabilitation of activities of daily living can be facilitated using computer-assisted approaches.
The existing approaches focus on cognitive training rather than the manual skills.
A virtual training system with intuitive user interface and force feedback was designed to improve the learning of the manual skills.
The study shows that system could be used as a training tool to complement conventional rehabilitation approaches.
[Abstract] Repetitive peripheral magnetic stimulation for activities of daily living and functional ability in people after stroke (Cochrane review) [with consumer summary] – PEDro
BACKGROUND: Repetitive peripheral magnetic stimulation (rPMS) is a form of therapy that creates painless stimulation of deep muscle structures to improve motor function in people with physical impairment from brain or nerve disorders. Use of rPMS for people after stroke has been identified as a feasible approach to improve activities of daily living and functional ability. However, no systematic reviews have assessed the findings of available trials. The effect and safety of this intervention for people after stroke currently remain uncertain.
OBJECTIVES: To assess the effect of rPMS for improving activities of daily living and functional ability in people after stroke. SEARCH METHODS: We searched the Cochrane Stroke Group Trials Register (August 2016), the Cochrane Central Register of Controlled Trials (CENTRAL; 2016, issue 8) in the Cochrane Library (August 2016), Medline OVID (November 2016), Embase OVID (August 2016), the Cumulative Index to Nursing and Allied Health Literature (CINAHL) in Ebsco (August 2016), PsycINFO OVID (August 2016), the Allied and Complementary Medicine Database (AMED) OVID (August 2016), Occupational Therapy Systematic Evaluation of Evidence (OTseeker) (August 2016), the Physiotherapy Evidence Database (PEDro) (October 2016), and ICHUSHI Web (October 2016). We also searched five ongoing trial registries, screened reference lists, and contacted experts in the field. We placed no restrictions on the language or date of publication when searching the electronic databases.
SELECTION CRITERIA: We included randomised controlled trials (RCTs) conducted to assess the therapeutic effect of rPMS for people after stroke. Comparisons eligible for inclusion were (1) active rPMS only compared with ‘sham’ rPMS (a very weak form of stimulation or a sound only); (2) active rPMS only compared with no intervention; (3) active rPMS plus rehabilitation compared with sham rPMS plus rehabilitation; and (4) active rPMS plus rehabilitation compared with rehabilitation only.
DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion. The same review authors assessed methods and risk of bias and extracted data. We contacted trial authors to ask for unpublished information if necessary. We resolved all disagreements through discussion.
MAIN RESULTS: We included three trials (two RCTs and one cross-over trial) involving 121 participants. Blinding of participants and physicians was well reported in all trials, and overall risk of bias was low. We found no clear effect of rPMS on activities of daily living at the end of treatment (mean difference (MD) -3.00, 95% confidence interval (CI) -16.35 to 10.35; low-quality evidence) and at the end of follow-up (MD -2.00, 95% CI -14.86 to 10.86; low-quality evidence). Investigators in one study with 63 participants observed no statistical difference in improvement of upper limb function at the end of treatment (MD 2.00, 95% CI -4.91 to 8.91) and at the end of follow-up (MD 4.00, 95% CI -2.92 to 10.92). One trial with 18 participants showed that rPMS treatment was not associated with improved muscle strength at the end of treatment (MD 3.00, 95% CI -2.44 to 8.44). Another study reported a significant decrease in spasticity of the elbow at the end of follow-up (MD -0.48, 95% CI -0.93 to -0.03). No studies provided information on lower limb function and death. Based on the GRADE approach, we judged the certainty of evidence related to the primary outcome as low owing to the small sample size of one study.
AUTHORS’ CONCLUSIONS: Available trials provided inadequate evidence to permit any conclusions about routine use of rPMS for people after stroke. Additional trials with large sample sizes are needed to determine an appropriate rPMS protocol as well as long-term effects. We identified three ongoing trials and will include these trials in the next review update.

[ARTICLE] Effect of upper extremity coordination exercise during standing on the paretic side on balance, gait ability and activities of daily living in persons with stroke – Full Text PDF
Objective: The purpose of this study was to determine the effect of upper extremity coordination exercise (UECE) during standing on the paretic side on balance, gait ability and activities of daily living (ADL) in persons with stroke.
Design: A randomized controlled trial.
Methods: A total of 27 patients with hemiplegic diagnosis after stroke were divided into two groups. Fourteen patients were in the study group and 13 patients were in the control group. The study group received conventional physical therapy and UECE during standing on the paretic side. The control group received conventional physical therapy and simple upper extremity exercise (SUEE). Subjects in both groups were given upper extremity training for 30 minutes per day, five times a week for 4 weeks. Initial evaluation was performed before treatment and reevaluated 4 weeks later to compare the changes of balance, gait ability and ADL (Korean version of modified Barthel index, K-MBI).
Results: Both groups showed a significant effect for balance, gait ability and ADL (p<0.05). In the Independent t-test, between both groups showed a significant effect for balance and gait ability except ADL (p<0.05).
Conclusions: In this paper, we investigated the changes in balance, walking, and ADL through UECE. We found significant changes in the study group and the control group. Results of the present study indicated that UECE during standing on the paretic side for 4 weeks had an effect on balance, gait ability and ADL (K-MBI) in persons with hemiplegia after stroke.
[Purpose] Investigation of the efficacy of robot-mediated therapy of the upper limb in patients with chronic stroke, in task-oriented training activities of daily living in real environment.
[Subjects and Methods] 20 patients, each more than one year post-stroke (13–71 months) received 20 sessions of upper limb robot-mediated therapy. No other treatment was given. Each therapy session consisted of a passive motion and an active task therapy. During the active therapy, subjects exercised 5 activities of daily living. Assessments of the subjects were blind, and conducted one month prior to, at the start, at the end, and three months after the therapy course. The following outcome measures were recorded: Fugl-Meyer Scale—upper extremity subsection, Modified Ashworth Scale, Action Research Arm Test, Functional Independence Measure, Barthel Index.
[Results] Significant improvements were observed between the start and the end of the therapy, except for Modified Ashworth Scale and Barthel Index. Results still held up at the follow-up visit three months later.
[Conclusion] Practicing activities of daily living in real environment with robot-mediated physical therapy can improve the motor and functional ability of patients, even with relatively good initial functions, and even years post-stroke.
Feeding and drinking are Activities of Daily Living which can be used to assess the motor control and functional ability of the upper limb. This paper presents the upper-limb kinematics during the execution of feeding and drinking activities, such analysis consisted in the measurement of angles of flexion for trunk and arm. Eight healthy subjects performed these activities in a simulated-environment while they were video recorded. Markers on anatomical landmarks were used to analyze the kinematics of the upper limb in the sagittal plane. Additionally an electro-hydraulic sensor was attached to each upper limb to assess the vertical position of the wrist relative to the shoulder. Results showed a difference on the angles of the elbow and trunk. The electro-hydraulic sensor showed to be an efficient way to record the vertical position of wrist.
[ARTICLE] Perceived ability to perform daily hand activities after stroke and associated factors: a cross-sectional study – Full Text
Despite that disability of the upper extremity is common after stroke, there is limited knowledge how it influences self-perceived ability to perform daily hand activities. The aim of this study was to describe which daily hand activities that persons with mild to moderate impairments of the upper extremity after stroke perceive difficult to perform and to evaluate how several potential factors are associated with the self-perceived performance.
Seventy-five persons (72 % male) with mild to moderate impairments of the upper extremity after stroke (4 to 116 months) participated. Self-perceived ability to perform daily hand activities was rated with the ABILHAND Questionnaire. The perceived ability to perform daily hand activities and the potentially associated factors (age, gender, social and vocational situation, affected hand, upper extremity pain, spasticity, grip strength, somatosensation of the hand, manual dexterity, perceived participation and life satisfaction) were evaluated by linear regression models.
The activities that were perceived difficult or impossible for a majority of the participants were bimanual tasks that required fine manual dexterity of the more affected hand. The factor that had the strongest association with perceived ability to perform daily hand activities was dexterity (p < 0.001), which together with perceived participation (p = 0.002) explained 48 % of the variance in the final multivariate model.
Persons with mild to moderate impairments of the upper extremity after stroke perceive that bimanual activities requiring fine manual dexterity are the most difficult to perform. Dexterity and perceived participation are factors specifically important to consider in the rehabilitation of the upper extremity after stroke in order to improve the ability to use the hands in daily life.
Disability of the upper extremity is common after stroke and almost 50 % of those affected have remaining impairments more than three months post-stroke [1, 2]. The impairments often lead to difficulties in performing daily hand activities , especially those that require the use of both hands, i.e., bimanual activities . The ability to perform bimanual activities is therefore an important goal in stroke rehabilitation, regardless of which hand that is affected .
The ability to perform daily activities can be objectively assessed by observations of different tasks in a standardized environment or by patient-reported questionnaires. The advantage of using questionnaires is that they often provide a better understanding of an individual’s self-reported everyday difficulties and thereby enable clinicians to design more individually targeted rehabilitation interventions . One questionnaire that is recommended for persons with disability of the upper extremity after stroke is the ABILHAND Questionnaire [4, 7, 8]. It assesses self-perceived ability to perform daily bimanual activities. Previous studies have focused on evaluating the psychometric properties of the ABILHAND [4, 8], but no study has thoroughly described which activities persons in a stable phase post stroke perceive difficult to perform.
In order to improve functioning of the upper extremity after stroke, it is important to understand which factors affect self-perceived ability to perform daily hand activities. Previous studies have shown that single factors, such as motor function, muscle strength, spasticity, somatosensation, dexterity, perceived participation and life satisfaction are moderately to strongly associated with the perceived ability [4, 9, 10, 11, 12, 13, 14, 15, 16, 17]. However, as several factors simultaneously may influence the ability to perform daily hand activities there is a need to understand how these factors are associated with the performance. To the best of our knowledge, only one study  has evaluated this association in persons in a stable phase after stroke. In that study by Harris and Eng , muscle strength, spasticity, somatosensation and pain were included in multivariate analyses and the authors found that muscle strength in the upper extremity and spasticity were the strongest contributing factors to the perceived ability to use the hands in daily activities. However, dexterity was omitted as a potentially associated factor in the analysis, which was addressed as a limitation of the study. In other studies, gender, dominance of the affected upper extremity, and social and vocational situations have been shown to be important factors for overall functioning after stroke [18, 19, 20, 21]. However, it is unclear how these factors are associated with the self-perceived ability.
Taken together, despite that disability of the upper extremity is common after stroke there is limited knowledge of which daily activities that are perceived difficult to perform and which factors that affect the self-perceived performance. The majority of previous studies have evaluated how single or few factors are associated with perceived daily hand activities. Thus, there is a need for more studies that take several factors into account simultaneously.
The aim of this study was to evaluate a) which daily activities persons with mild to moderate impairments of the upper extremity after stroke perceive difficult to perform and b) how several factors (age, gender, social and vocational situation, affected hand, upper extremity pain, spasticity, grip strength, somatosensation, manual dexterity, perceived participation and life satisfaction) are associated with the self-perceived performance.
[Abstract] Functional range of motion of the hand joints in activities of the International Classification of Functioning, Disability and Health
Cross-sectional research design.
Active range of motion (AROM) is used as indicator of hand function. However, functional range of motion (FROM) data are limited, and fail to represent activities of daily living (ADL).
Purpose of the Study
To estimate dominant hand FROM in flexion, abduction and palmar arching in people under 50 years of age performing ADL.
AROMs and hand postures in 24 representative ADL of the International Classification of Functioning, Disability and Health (ICF) were recorded in 12 men and 12 women. FROM data were reported by activity and ICF area, and compared with AROMs. The relationship between ROM measures to gender and hand size was analyzed by correlation.
FROM was 5° to 28° less than available AROM depending on the joint and movement performed.
Joints do not necessarily move through full AROM while performing ADL which has benefits in retaining function despite loss of motion. This may also suggest that ADL alone are insufficient to retain or restore full AROM.
Therapists should consider FROM requirements and normal AROM when defining hand therapy goals, interventions and evaluating the success of treatment.
