The effect of enhanced trunk control on balance and falls through bilateral upper extremity exercises among chronic stroke patients in a standing position.

[Purpose] This study examined the effects of bilateral upper extremity exercises on trunk control, balance, and risk of falls in stroke patients. [Subjects and Methods] A total of 30 study subjects were selected and randomly divided into experimental and control groups containing 15 subjects each, who received bilateral upper extremity activities and conventional rehabilitation treatment, respectively. [Results] There were statistically significant differences between groups in all sub-items and total trunk impairment and Berg Balance scale scores. Significant differences between groups were also observed in all sub-items of the trunk impairment scale, except for static sitting balance. [Conclusion] Bilateral upper extremity exercises are effective for trunk control and balance as well as for fall prevention.
