effect of hand rehabilitation robot on acute stroke

Conditions: Stroke; Rehabilitation

Summary: this study aimed to evaluate the effectiveness of hand robot-assisted therapy on functionality, fine motor skills, and activities of daily living (adls) in acute stroke rehabilitation. a total of 30 participants aged 40-60 years with a diagnosis of stroke were randomly assigned to two groups: a neurodevelopmental treatment (ndt) group (n=15) and a hand robot-assisted therapy group (n=15). the ndt group received a standard rehabilitation program, including strengthening, stretching, and fine motor activities, three times per week for 8 weeks. the hand robot group received the same ndt program with the addition of hand robot therapy sessions three times per week for 8 weeks. outcome measures included the abilhand stroke questionnaire for hand function, the barthel index (bi) for adls, the disabilities of the arm, shoulder, and hand (dash) questionnaire for functionality, the nine-hole peg test (nhpt) for fine motor skills, and the modified ashworth scale (mas) for spasticity. both groups showed significant improvements in adls, fine motor skills, and abilhand scores after treatment (p\<0.05). the hand robot group demonstrated superior improvements in bi and nhpt scores compared to the ndt group (p\<0.05), while other parameters showed comparable results between groups. hand robot-assisted therapy may serve as a complementary approach to neurodevelopmental treatment in individuals with acute stroke.

this study aimed to investigate the effectiveness of hand robot-assisted therapy on functionality, fine motor skills, and activities of daily living (adls) in individuals undergoing acute stroke rehabilitation. a total of 30 participants, aged 40-60 years and diagnosed with stroke, were randomly assigned into two groups: a neurodevelopmental treatment (ndt) group (n=15) and a hand robot-assisted therapy group (n=15). the ndt group participated in a rehabilitation program consisting of strengthening, stretching, and fine motor activities, administered three times per week for 8 weeks. the hand robot-assisted therapy group received the same ndt program with the addition of hand robot therapy, performed three times per week for 8 weeks immediately after the ndt sessions. several assessment tools were used to evaluate outcomes: the abilhand stroke questionnaire for hand function, the barthel index (bi) for adls, the disabilities of the arm, shoulder, and hand (dash) questionnaire for functionality, the nine-hole peg test (nhpt) for fine motor skills, and the modified ashworth scale (mas) for spasticity. baseline characteristics, including age, sex, and stroke duration, were homogeneously distributed between groups. both groups exhibited significant improvements in adls, fine motor activities, abilhand scores, and nhpt results post-treatment compared to baseline (p\<0.05). however, the hand robot-assisted therapy group demonstrated significantly greater improvements in bi and nhpt scores compared to the ndt group (p\<0.05). for other parameters, both groups showed similar outcomes. these findings suggest that hand robot-assisted therapy can be effectively utilized as a complementary approach to neurodevelopmental treatment in acute stroke rehabilitation, particularly in enhancing adls and fine motor skills.
