A novel application of infrared-C (IR-C) radiation (3-1000 μm) on hemiparetic stroke patients was evaluated. Hot compresses (HC) were used on the paretic shoulders of patients in this placebo-controlled trial to investigate the effects of IR-C on skin temperature, electrodermal conductance (EC) and pain relief.
Skin temperature at the center of the middle deltoid (CMD), Quchi (LI11), and the center of the third metacarpal bone on dorsum of hand (COT) of the subjects at Brunnstrom stage 3-5 before and after IR-C HC, were examined. Meanwhile, EC was measured on Hegu (LI4), Quchi and Juanyu (LI15). Pain intensity was evaluated before and after treatment.
Skin temperature increased significantly at the CMD and COT on the paretic side in males. In females after treatment, similar skin temperatures were found in each measured region on both the paretic and non-paretic sides. The EC on the paretic side tended to be higher than the non-paretic side before treatment. After treatment, the EC on paretic side declined in both sexes and became even lower than the non-paretic side in females. Pain intensity was lessened after treatment especially in males, which appeared to correspond with an increase in skin temperature and a decrease in EC.
IR-C hot compress is a promising method for stroke patients in rehabilitation. Physiological mechanisms of this treatment were proposed and summarized from this research.
评估红外-C（IR-C）辐射（3 - 1000μm）在偏瘫性中风患者中的一种新应用。在这项安慰剂对照试验中，对患者的患侧肩部进行热敷（HC），以研究IR-C对皮肤温度、皮电导率（EC）和疼痛缓解的影响。
检查处于Brunnstrom 3 - 5期的受试者在接受IR-C热敷前后，其三角肌中部中心（CMD）、曲池（LI11）以及手背第三掌骨中心（COT）的皮肤温度。同时，在合谷（LI4）、曲池和肩髃（LI15）测量皮电导率。在治疗前后评估疼痛强度。
男性患侧的CMD和COT处皮肤温度显著升高。治疗后，女性患侧和非患侧各测量区域的皮肤温度相似。治疗前，患侧的皮电导率往往高于非患侧。治疗后，两性患侧的皮电导率均下降，女性患侧的皮电导率甚至低于非患侧。治疗后疼痛强度减轻，尤其是男性，这似乎与皮肤温度升高和皮电导率降低相对应。
IR-C热敷是中风患者康复的一种有前景的方法。本研究提出并总结了这种治疗方法的生理机制。
