With effective rehabilitation, stroke patients can partially regain their motor control and continue their activities of daily living. Motor function changes in the unaffected hand of stroke patients with hemiplegia. However, these changes are often ignored by clinicians owing to the extent of motor disability of the affected hand. Research group at Shanghai University of Sport, China led by Prof. Zhusheng Yu based on finger tapping frequency and Lind-mark hand function score have found that the motor function of unaffected hands in stroke patients was poorer than that of a healthy control hand. After 2 weeks of rehabilitation treatment, motor function of the unaffected hand of stroke patients was obviously improved. Therefore, attention should also be paid to motor function in the unaffected hand of stroke patients with hemiplegia during rehabilitation.
