摘要: 目的

观察偏瘫上肢施加不同的限制方法,在站立位姿势维持及常速步行中,对偏瘫上肢肘屈肌活跃性和平衡稳定的即刻效应。

方法

2018年9月至12月,南京医科大学附属苏州科技城医院住院或门诊治疗的脑卒中患者14例,分别于无限制、肘伸直型支具固定、健手辅助患侧上肢伸直于身后、健手辅助患侧肩前屈90° 4种条件下,采用无线表面肌电设备观察站立和步行时偏瘫侧肘屈肌收缩率(屈肌的平均积分肌电值/伸肌的平均积分肌电值),Biodex平衡系统观察站立20 s身体摆动指数。

结果

站立和步行时,支具固定下肘屈肌收缩率最大(F > 2.687, P < 0.05)。站立时,健手辅助患侧肩前屈90°下摆动指数最大(F = 21.091, P < 0.05)。

结论

支具固定限制会导致患侧肘屈肌收缩率增高,不是降低偏瘫上肢屈肌活跃性的有效方法;健手托举患手限制会导致平衡功能降低。

Abstract: Objective

To observe the affected elbow flexor activities and balance of stroke patients in standing and walking as fixing the affected upper extremity with different methods.

Methods

From September to December, 2018, 14 stroke patients from Affiliated Suzhou Science & Technology Town Hospital of Nanjing Medical University were included. They were measured elbow flexor contraction ratio (integrated electromyogram of flexor/integrated electromyogram of antagonist) with wireless surface electromyography as standing and walking in normal speed, and sway index with Biodex as standing, in four conditions: the affected arm without fixing, and fixed with elbow orthosis, and with unaffected hand backwards and forwards.

Results

The contraction ratio was the most as the arm fixed with elbow orthosis in both standing and walking (F > 2.687, P < 0.05). The sway index was the most as the arm fixed with unaffected hand forwards (F = 21.091, P < 0.05).

Conclusion

The elbow orthosis restraint may lead to increased contraction of the affected elbow flexor, which is unsatisfactory to inhibit flexor activity of the upper extremities; while restraint of unaffected hand forwards may lead to instable balance.

Key words: stroke, upper extremity restraint, balance, flexor
