The symptoms are usually sensed in the first three radial fingers and the lateral side of the ring finger because these areas are innervated by the median nerve. Objective: To assess hand function among patient with Carpal Tunnel Syndrome (CTS). Methods: This was a descriptive study in which 41 subjects (27 females and 14 males) were included from Ghurki trust teaching hospital, Lahore and Shalamar hospital, Lahore (from August 2018 to October 2018) according to inclusion criteria. Samples were collected according to WHO (World Health Organization) calculator. Hand function was measured with Boston Carpal Tunnel Questionnaire (BCTQ). Results: Majority of the patients with CTS fell into mild functional severity and mild symptom severity. The mean score for functional severity was 2.34 and for symptom severity it was 2.97. Conclusion: Activities of daily living such as grasping, writing, gripping and carrying objects were affected by the symptoms of pain, numbness, tingling and weakness in the patients suffering from CTS.展开更多

These changes are often ignored by clinicians owing to the extent of motor disability of the affected hand. Finger tapping frequency and Lind-mark hand function score showed that the motor function of unaffected hands in stroke patients was poorer than that of a healthy control hand. After 2 weeks of rehabilitation treatment, motor function of the unaffected hand of stroke patients was obviously improved. Therefore, attention should also be paid to motor function in the unaffected hand of stroke patients with hemiplegia during rehabilitation.展开更多

Methods: Seventy-six cases of hemiplegia patients with ischemic stroke were divided into the treatment group and the control group(n=38 in each). Based on the Brunnstrom's stage of Xingnao Kaiqiao acupuncture combined with rehabilitation training was used in the treatment group, and the control group was given rehabilitation training. FuglMeyer Assessment of the upper extremity(FMA-UE), Action Research Arm Test(ARAT) and Simple Test for Evaluating hand Function(STEF) were adopted separately to compare scores before treatment and 8 weeks after treatment. Results: The difference was not statistically significant in the two groups of patients for comparison of FMA-UE, ARAT and STEF scores before treatment(P>0.05). The difference was statistically significant in the two groups of score comparison of FMA-UE, ARAT and STEF after treatment(P<0.05). Conclusion: The Xingnao Kaiqiao acupuncture has its unique advantages in improving recovery of motor function of upper limb and hand in recovery period after stroke.展开更多

While some studies supporting this theory have focused on Chinese characters, less attention has been paid to their semantic radicals. Indeed, there is still disagreement about whether these radicals are processed independently. The present study investigated whether radicals are processed separately and, if so, whether this processing occurs in sensory-motor regions. Materials consisted of 72 high-frequency Chinese characters, with 18 in each of four categories： hand-action verbs with and without hand-radicals, and verbs not related to hand actions, with and without hand-radicals. Twenty-eight participants underwent functional MRI scans while reading the characters. Compared to characters without hand-radicals, reading characters with hand-radicals activated the right medial frontal gyrus. Verbs involving hand-action activated the left inferior parietal lobule, possibly reflecting integration of information in the radical with the semantic meaning of the verb. The findings may be consistent with embodied semantics theory and suggest that neural representation of radicals is indispensable in processing Chinese characters.展开更多

Methods Sixty cases of post-stroke hand motor impairment were randomly divided into an observation group and a control group, 30 cases in each one. The conventional medication, physical therapy, occupational therapy and other rehabilitation trainings were applied in both groups. In observation group, Zhongzhu （中渚 TE 3） and Waiguan （外关TE 5） were punctured. The assessment was performed with neurologie deficit scoring of the National Institutes of Health Stroke Scale （NIHSS）, hand motor function, walking ability and the modified Barthel index scale of the Activities of Daily Living （ADL） in both groups before and after treatment. Results After treatment, the scores of hand function, walking ability, ADL and NIHSS were improved in both groups as compared with those before treatment （all P〈0.01）. The improvements of hand function, walking ability and ADL ：in observation group were superior to those in control group （all P〈0.05）.

文摘目的:基于《国际功能、残疾和健康分类》框架,系统评价不同类型3D打印外骨骼对脑卒中患者手功能康复的临床疗效。方法:检索PubMed、Cochrane Library、Web of Science、Embase、中国知网和中国生物医学文献数据库,收集2015年1月至2024年12月发表的3D打印外骨骼干预脑卒中患者手功能的文献。由2名研究者独立筛选文献、提取资料并进行方法学质量评价,遵循PRISMA指南规范系统综述流程。结果:最终纳入13篇文献,涉及美国、中国、荷兰、意大利、新加坡和土耳其6个国家,共62例脑卒中患者。根据Brunnstrom分期将外骨骼分为辅助型(Ⅰ期)、矫正型(Ⅱ-Ⅲ期)、训练型(Ⅳ-Ⅵ期)和代偿型(Ⅳ-Ⅵ期)4类,干预方式包括机构康复、家庭康复和机构-家庭康复,干预方案为每次15-90 min,每周3-7次,持续5-8周。研究结果显示:辅助型外骨骼改善精细手使用能力以及自我照顾能力;矫正型外骨骼改善关节活动功能、肌张力、握力以及精细手使用能力;训练型外骨骼改善关节活动功能、上肢肌肉力量以及自我照顾能力;代偿型外骨骼提升精细手使用能力及手和手臂使用能力。结论:基于《国际功能、残疾和健康分类》框架的证据表明,3D打印外骨骼改善脑卒中患者手部功能以及活动和参与能力。建议根据Brunnstrom分期选择匹配的外骨骼类型,并制定个体化干预方案,以实现康复的最佳效果。
文摘目的:腕手矫形器是一种常见的上肢功能障碍康复辅具,对脑卒中后手功能障碍患者的疗效存在争议。该文系统评价腕手矫形器对脑卒中患者手功能障碍的康复效果。方法:系统检索中国知网、万方、维普、SinoMed、PubMed、Embase、Web of Science、Cochrane Library等数据库公开发表的腕手矫形器在脑卒中患者手功能康复中应用的随机对照试验,其中试验组采用腕手矫形器和常规康复治疗,对照组采用常规康复治疗,检索时限为各数据库建库到2024年7月。由2位研究者独立开展文献筛选、提取资料,并依据Cochrane风险偏倚评估工具评价文献质量,使用RevMan 5.4软件进行Meta分析。结果:最终纳入8篇文献,共305例患者。Meta分析结果显示:试验组改良Ashworth评分低于对照组[MD=-0.24,95%CI(-0.36,-0.12),P<0.0001],Fugl-Meyer上肢运动功能评分和改良Barthel评分[SMD=0.97,95%CI(0.51,1.43),P<0.0001;SMD=1.00,95%CI(0.05,1.94),P=0.04]均高于对照组,两组握力比较差异无显著性意义[MD=-0.89,95%CI(-5.37,3.58),P=0.70]。结论:腕手矫形器能够降低脑卒中患者腕手关节肌张力,提高患者手运动功能与日常生活活动能力,但对患者握力无明显改善。需注意的是,研究总样本量仅305例,且部分指标(如握力)仅纳入2篇文献,统计效力不足,未来需更多大样本、高质量的随机对照试验进行验证。
文摘目的:探讨透明质酸和脂肪胶填充对断指再植术后指体萎缩患者手功能及生活质量的影响。方法:选取2020年1月-2024年1月笔者科室收治的102例断指再植术后出现指体萎缩的患者作为研究对象,采用随机数字表法分为脂肪移植组和透明质酸组,每组51例,两组萎缩指体皮下分别填充脂肪胶和透明质酸。填充后随访1个月,对两组患者手功能[密歇根州手功能评估量表(Michigan Hand Outcomes Questionnaire,MHQ)]、两点辨别觉、生活质量(Barthel指数)、手功能优良率(中华医学会外科学会断指再植功能评定标准)及并发症进行评定,并进行统计比较。结果:填充1个月后,脂肪移植组患者疼痛评分低于透明质酸组,但外观、日常活动、工作情况、手功能满意度以及手整体功能评分均高于透明质酸组(P<0.05);脂肪移植组患者Barthel指数高于透明质酸组(P<0.05),两点辨别觉距离短于透明质酸组(P<0.05);两组患者手功能恢复优良率及并发症发生情况比较差异无统计学意义(P>0.05)。结论:脂肪胶填充对断指再植术后指体萎缩患者手功能和生活质量的改善作用优于透明质酸,且安全性好,值得临床推荐。
