[Purpose] This study evaluated effects of a high-intensity linear polarized near-infrared ray irradiation for mitigation of muscle hypertonia. [Subjects] The subjects were 20 patients with cerebrovascular disease. [Methods] Subjects were randomly allocated to an intervention or control group. The intervention group received irradiation of the triceps surae. Passive range of motion and passive resistive joint torque of ankle dorsiflexion were measured before and after the intervention in knee extended and flexed positions. [Results] In the knee extended position, the mean changes in passive range of motion were 2.70° and -0.50° in the intervention and control groups, respectively, and the mean changes in passive resistive joint torque were -1.42 and -0.26 N·m in the intervention and control groups, respectively. In the knee flexed position, the mean changes in passive range of motion were 3.70° and 0.70° in the intervention and control groups, respectively, and the mean changes in passive resistive joint torque were -2.38 and -0.31 N·m in the intervention and control groups, respectively. In both knee positions, the mean changes in the two indices were greater in the intervention group than in the control group. [Conclusion] High-intensity linear polarized near-infrared ray irradiation increases passive range of motion and decreases passive resistive joint torque.
[目的] 本研究评估高强度线性偏振近红外线照射对减轻肌肉张力亢进的效果。[对象] 对象为20例脑血管疾病患者。[方法] 将对象随机分为干预组和对照组。干预组接受腓肠肌照射。在膝关节伸展和屈曲位干预前后测量踝关节背屈的被动活动范围和被动抵抗性关节扭矩。[结果] 在膝关节伸展位，干预组和对照组被动活动范围的平均变化分别为2.70°和-0.50°，干预组和对照组被动抵抗性关节扭矩的平均变化分别为-1.42和-0.26 N·m。在膝关节屈曲位，干预组和对照组被动活动范围的平均变化分别为3.70°和0.70°，干预组和对照组被动抵抗性关节扭矩的平均变化分别为-2.38和-0.31 N·m。在两个膝关节位，干预组两个指标的平均变化均大于对照组。[结论] 高强度线性偏振近红外线照射可增加被动活动范围并降低被动抵抗性关节扭矩。
