3D打印分指板和传统分指板对脑卒中患者手指痉挛的对照研究

Randomized Controlled Study of 3D Print Fingerboard and Traditional Fingerboard on Treatment of Stroke Patients with Finger Spasm

目的:观察3D打印分指板与传统分指板在脑卒中患者康复治疗中降低手部痉挛和提高手功能方面的疗效比较。方法:将60例住院脑卒中患者按照随机数字表法分为治疗组和对照组各30例,治疗组定制并佩戴3D打印分指板,对照组佩戴传统分指板。分别观察患者在佩戴初及3个月后的依从性、不适主诉、患手握力、肌张力、关节活动度和手功能变化。结果:治疗组26例和对照组24例最终获得完整资料。2组佩戴3个月后比较,治疗组平均佩戴分指板时间较对照组长(P<0.01),手指肌张力较对照组低(P<0.01);治疗前后比较,治疗组握力指数增强(P<0.01),2组手指肌张力均有降低(P<0.01),2组手运动模式均有提高(P<0.01)。结论:3D打印分指板有精准和个性化特点,作为康复治疗辅助支具,较传统分指板更有利于治疗脑卒中患者的手部痉挛。

Objective： Through the research of scanning, modeling and 3D printing technology, to make personalized 3D print fin- gerboard, and to observe the effect of 3D print fingerboard in reducing hand spasm and improving hand function of stroke patients in rehabilitation compared with the traditional fingerboard. Methods： A total of 60 cases of hospitalized stroke patients were randomly di- vided into treatment group and control group, 30 cases in each group, the treatment group treated by custom 3D fingerboard and the control group treated by traditional fingerboard. The compliance, discomfort complaints, hand grip strength, muscle tension, joint mo- bility and hand function changes were observed respectively at the beginning and after 3 months of treatment. Results： Complete data were obtained in 26 cases in the treatment group and 24 cases of the control group. Compared with the control group after 3 months of treatment, the average time in wearing fingerboard of the treatment group was longer （P〈 0.01）, and the finger muscle tension of the treatment group was lower （P〈0.01）. Compared with before treatment, the hand grip strength index in the treatment group rose （P〈 0.01）, and the fmger muscle tension in two groups decreased and the hand function improved （P〈0.01）. Conclusion： 3D print finger-board has the features of accurate and personalization as rehabilitation aids. Compared with traditional fingerboard, 3D print finger-board has more conducive to the treatment of stroke patients with finger spasm.
