Effects of Robot-Assisted Rehabilitation on Hand Function of People With Stroke: A Randomized, Crossover-Controlled, Assessor-Blinded Study.

IMPORTANCE: The effects of robot-assisted task-oriented training with tangible objects among patients with stroke remain unknown. OBJECTIVE: To investigate the effects of robot-assisted therapy (RT) with a Gloreha device on sensorimotor and hand function and ability to perform activities of daily living (ADLs) among patients with stroke. DESIGN: Randomized, crossover-controlled, assessor-blinded study. SETTING: Rehabilitation clinic. PARTICIPANTS: Patients (N = 24) with moderate motor and sensory deficits. INTERVENTION: Patients participated in 12 RT sessions and 12 conventional therapy (CT) sessions, with order counterbalanced, for 6 wk, with a 1-mo washout period. OUTCOMES AND MEASURES: Performance was assessed four times: before and after RT and before and after CT. Outcomes were measured using the Fugl-Meyer Assessment-Upper Extremity (FMA-UE), Box and Block Test, electromyography of the extensor digitorum communis (EDC) and brachioradialis, and a grip dynamometer for motor function; Semmes-Weinstein hand monofilament and the Revised Nottingham Sensory Assessment for sensory function; and the Modified Barthel Index (MBI) for ADL ability. RESULTS: RT resulted in significantly improved FMA-UE proximal (p = .038) and total (p = .046) and MBI (p = .030) scores. Participants' EDC muscles exhibited higher efficacy during the small-block grasping task of the Box and Block Test after RT than after CT (p = .050). CONCLUSIONS AND RELEVANCE: RT with the Gloreha device can facilitate whole-limb function, leading to beneficial effects on arm motor function, EDC muscle recruitment efficacy, and ADL ability for people with subacute and chronic stroke. WHAT THIS ARTICLE ADDS: The evidence suggests that a task-oriented approach combined with the Gloreha device can facilitate engagement in whole-limb active movement and efficiently promote functional recovery.

Evaluation of a 3D-Printed Writing Assistive Device for People With Brain Injury.

Three-dimensional-printed assistive devices hold promise for improving writing abilities, yet factors influencing device selection and their impact on satisfaction and effectiveness remain unclear, especially in adults, as they are typically tested on children. The aim of this article is to assess the efficacy and satisfaction with a writing assistive device at different angles among individuals with brain injury and explore device selection factors. Twenty-six participants with brain injuries selected their preferred device angle. Writing speed, quality, and satisfaction were recorded. Immediate speed improvements were significant at 5° and 30° (p = .006, .013, respectively). Satisfaction scores did not significantly differ among angles. Normotonia in elbow (p < .001; odds ratio: 3.403) and wrist (p ≤ .001; odds ratio: 2.695) muscles increased the likelihood of selecting the 5° device. Immediate speed improvements at specific angles highlight the influence of muscle normotonia on device selection, vital for tailored brain injury rehabilitation.

Evaluation of a 3D-Printed Writing Assistive Device for People With Brain InjuryThis study, titled "Evaluation of a 3D-Printed Writing Assistive Device for People with Brain Injury," aimed to understand how 3D-printed devices could improve writing for individuals with brain injuries. The researchers explored the effectiveness and satisfaction of using these devices at different angles (5°, 20°, and 30°) among 26 participants with brain injuries. Participants chose the device angle that felt most comfortable to them, and the study measured their writing speed, quality, and satisfaction. The findings revealed that using 3D-printed writing devices significantly improved writing speed immediately, regardless of the chosen angle (5° or 30°). Satisfaction scores were similar across all angles. Interestingly, individuals with normal elbow and wrist muscle tone were more likely to prefer the 5° device. In summary, this study concludes that 3D-printed writing devices can promptly enhance writing for people with brain injuries. The specific angle of the device significantly affect outcomes, and participants generally find satisfaction with their choice. If you have normal elbow and wrist muscle tone, the 5° angle may be the optimal choice for you.

Effects of 3D-printed assistive device on daily life function in patients with neurological impairment: a pilot study.

PURPOSE: To explore the effects of customized 3D-printed assistive technology (AT) on functional performance and feasibility in patients with neurological impairment. METHODS: Patients with neurological impairment were recruited and randomized into customized 3D-printed assistive device group (group 1; n = 17) or standard device group (group 2; n = 14). The device was designed to assist their writing, spoon using, and typing. Each patient underwent 4-week intervention with the device (30 min per session, twice a week). RESULTS: We observed significant differences in shoulder abduction (p = .00), external rotation (p = .01), and internal rotation (p = .02) in group 1. And significant differences in abduction (p = .05) and external rotation (p = .05) between the 2 groups. Group 1 achieved significant improvements in writing without AT (p = .04) and with AT (p = .02), spoon use without AT (p = .02) and with AT (p = .03), and hemiplegia-side typing with AT (p = .00). Group 2 achieved significant improvements in writing without AT (p = .01), hemiplegia-side typing without AT (p = .01), and bil-side typing with AT (P = .05). Moreover, no significant differences were noted in other outcome measures. CONCLUSIONS: This study demonstrated that customized 3D-printed AT can improve shoulder active motion for patients with neurological impairment. A positive effect in functional hand tasks after AT intervention. Offering customized AT with specific training could enhance the efficacy of interventions. The feasibility of using 3D printing technology to produce customized AT, which has the potential to be cost-effective and efficient.

Effects of a wearable sensor-based virtual reality game on upper-extremity function in patients with stroke.

BACKGROUND: PABLO is a virtual reality game where a motion sensor system is used. Few studies have investigated the effects of the PABLO system in stroke rehabilitation. We investigated the effects of upper-extremity virtual reality training with the PABLO system in patients with stroke. METHODS: Stroke patients were randomly assigned to the virtual reality (n = 19) or standard rehabilitation groups (n = 18). Total of 18 sessions were conducted twice per week. The primary outcome measure was the Fugl-Meyer Assessment-Upper Extremity subscale. Secondary outcome measures included the active ranges of motion of the shoulder and elbow, the box and block test, hand grip strength, and the Stroke Impact Scale. Enjoyment of activities and side effects were also recorded. FINDINGS: No difference was observed between two groups in primary outcome. Virtual reality group exhibited greater improvements in the hand dexterity between groups (p = .05). In active motion, virtual reality group showed greater improvement in shoulder flexion between groups (p = .03). Virtual reality group also showed greater improvements in elbow pronation between groups (p = .03). The groups differed in their assessments of how enjoyment the rehabilitation activities were found (p = .01). No significant differences between groups were observed in any other tests. INTERPRETATION: Interventions based on the PABLO virtual reality system improved upper extremity hand function, shoulder and elbow movements, and elicited a higher degree of enjoyment from study participants, than did traditional treatment. TRIALS REGISTRATION: The study protocol was registered at ClinicalTrials.gov PRS (No.NCT04296032).

Robotic-assisted hand therapy for improvement of hand function in children with cerebral palsy: a case series study.

BACKGROUND: Most types of robot-assisted training (RT) have been used in Cerebral Palsy (CP) patients only focus on proximal upper extremity. Few of study investigated the effect of distal upper extremity training. CASE REPORT: Pediatric CP patients (N.=7) participated the RT sessions for 6 weeks (12 60-min sessions 2 times a week). Performance was assessed at 3 time points (pretest, posttest, and 1-month follow-up). RT significantly improved in body structure and function domains: FMA-UE scores (P=0.002). On electromyography, significant improvements in the mean brachioradialis muscle amplitude (P=0.015) and electrical agonist-antagonist muscle ratio (P=0.041) in the 1-inch cube-grasping task. The effects were maintained after 1 month. CLINICAL REHABILITATION IMPACT: RT using a Gloreha device which focuses on the distal part of the upper limb benefit on body structure and function, including upper-extremity motor function, brachioradialis muscle recruitment, and coordination in children with cerebral palsy.

The effects of gardening on quality of life in people with stroke.

BACKGROUND: Compared with traditional rehabilitation, gardening has been viewed as a more occupation-based intervention to help patients improve functional performance. However, there is still a need for evidence-based research into what factors interact to create the beneficial effects of gardening for people who have sustained a cerebral vascular accident (CVA). OBJECTIVE: To explore how plant, gender, and the time after stroke onset influenced improvements in the quality of life of patients in a gardening program. METHODS: One treatment of tending short-term plants, and another treatment of tending long-term plants were compared. Quality of life improvement was evaluated according to three factors: plant, gender, and the time after stroke onset. The data were analyzed with 2k replicated factorial designs. RESULTS: The 2k factorial design with replication indicated significant effects on both the social role and the family role. For the social role, the interaction of plant and gender difference was significant. For the family role, the significant effects were found on interaction of plant with both gender and the time after stroke onset. CONCLUSIONS: Tending plants with different life cycles has varied effects on the quality of life of people who have sustained a CVA. Factors related to gender and the time after stroke onset influenced role competency in this sample.
