Abdominal strengthening exercises are important for stroke patients; however, there is a lack of research on therapeutic exercises for increasing abdominal muscle activity in stroke patients.
We investigated the effects of non-paretic arm exercises using a tubing band on abdominal muscle activity in stroke patients.
In total, 18 hemiplegic subjects (13 males, 5 females) were recruited. All subjects performed non-paretic arm exercises involving three different shoulder movements (extension, flexion, and horizontal abduction) using an elastic tubing band. Surface electromyography (EMG) signals were recorded from the rectus abdominis (RA), external oblique (EO), and internal oblique (IO) muscles bilaterally during non-paretic arm exercises.
EMG activities of abdominal muscles during non-paretic arm extension and horizontal abduction were increased significantly versus shoulder flexion when subjects performed the arm exercise in a seated position. Muscle activity of the EO was significantly greater in the paretic than the non-paretic side during non-paretic arm extension and horizontal abduction.
We suggest that non-paretic arm extension and horizontal abduction exercises using an elastic tubing band may be effective in increasing abdominal muscle activity.
腹部强化运动对中风患者很重要；然而，对于增加中风患者腹部肌肉活动的治疗性运动，研究还很缺乏。
我们研究了使用管状带进行非瘫痪侧手臂运动对中风患者腹部肌肉活动的影响。
共招募了 18 名偏瘫受试者（13 名男性，5 名女性）。所有受试者均使用弹性管状带进行涉及三个不同肩部运动（伸展、屈曲和水平外展）的非瘫痪侧手臂运动。在非瘫痪侧手臂运动期间，从双侧腹直肌（RA）、外斜肌（EO）和内斜肌（IO）记录表面肌电图（EMG）信号。
与肩部屈曲相比，受试者在坐姿下进行手臂伸展和水平外展时，腹部肌肉的 EMG 活动显著增加。在非瘫痪侧手臂伸展和水平外展时，EO 的肌肉活动在瘫痪侧明显大于非瘫痪侧。
我们认为，使用弹性管状带进行非瘫痪侧手臂伸展和水平外展运动可能有效增加腹部肌肉活动。
