Impaired sitting balance is an important and time-consuming complication for stroke patients. We examined the effect of the use of an angular biofeedback device in addition to physical therapy in training stroke patients with impaired sitting balance compared with outcome in patients receiving conventional physical therapy only.
The biofeedback group consisted of 24 patients who received angular biofeedback training in addition to conventional physical therapy. The number of biofeedback signals and the lengths of time a patient could sit balanced throughout a period of 5 minutes before the training program, after 10 days of treatment, and at discharge were recorded and compared with those of the control group of 13 patients who received conventional physical therapy only.
It was found that 75% of the biofeedback group gained sitting balance after 10 days of treatment in comparison with 15.4% of the control group (P < .001). At discharge, 91.6% of the biofeedback group and 84.6% of the control group gained sitting balance (P = .510), and 45.8% of the biofeedback group and 46.2% of the control group managed independent ambulation (P = .985). The mean rehabilitation periods among the ambulatory patients of the biofeedback and control groups were 9.45 +/- 0.71 and 13.83 +/- 1.70 weeks, respectively (P = .049). The mean training time in which the biofeedback group gained sitting balance was significantly shorter than that of the control group (P < .001).
Angular biofeedback intervention, by providing earlier postural trunk control, is a useful adjunct to conventional physical therapy in the rehabilitation of stroke patients with impaired sitting balance.
坐位平衡受损是卒中患者的一种重要且耗时的并发症。我们研究了在物理治疗基础上使用角度生物反馈装置对坐位平衡受损的卒中患者进行训练的效果，并与仅接受传统物理治疗的患者的结局进行比较。
生物反馈组由24例患者组成，他们在接受传统物理治疗的基础上还接受了角度生物反馈训练。记录训练前、治疗10天后及出院时患者在5分钟内能够保持坐位平衡的生物反馈信号数量和时间长度，并与仅接受传统物理治疗的13例患者的对照组进行比较。
发现生物反馈组75%的患者在治疗10天后获得了坐位平衡，而对照组为15.4%（P<0.001）。出院时，生物反馈组91.6%的患者和对照组84.6%的患者获得了坐位平衡（P = 0.510），生物反馈组45.8%的患者和对照组46.2%的患者能够独立行走（P = 0.985）。生物反馈组和对照组能够行走的患者的平均康复期分别为9.45±0.71周和13.83±1.70周（P = 0.049）。生物反馈组获得坐位平衡的平均训练时间明显短于对照组（P<0.001）。
角度生物反馈干预通过提供早期的躯干姿势控制，是传统物理治疗对坐位平衡受损的卒中患者进行康复治疗的有用辅助手段。
