PURPOSE
To investigate the effect of red and green light beams on gait and freezing of gait (FOG) in persons with Parkinson's disease (PD).
METHODS
Seven persons with PD who experienced FOG participated in the study. Gait and turning performances were studied while walking with canes with red, green, and no light beams while "off" and "on" anti-Parkinsonian medications. Gait speed, cadence, and stride were recorded. Time and number of freezing episodes were recorded during a 50-foot walk and a 360° turn.
RESULTS
During 'off' medication, compared to no light, stride length improved when using the green light, but not the red. During the 50-foot walk, freezing episodes were reduced when using the green light compared to both the red and no light. During the 360° turn, time, number of steps and number of freezing episodes were reduced using the green light compared to the red and no light. During 'on' medication, gait speed and stride length improved more with the green light compared to the red. Neither color showed any effect on cadence during either medication state.
CONCLUSION
A green light improved gait and alleviate FOG in persons with PD better than a red light or no light.
目的
研究红光和绿光光束对帕金森病（PD）患者步态和步态冻结（FOG）的影响。
方法
7名经历过FOG的PD患者参与了该研究。在“关”和“开”抗帕金森病药物的情况下，使用带有红光、绿光和无光束的手杖行走时，研究步态和转弯表现。记录步态速度、步频和步幅。在50英尺行走和360°转弯过程中记录冻结发作的时间和次数。
结果
在“关”药期间，与无光束相比，使用绿光时步幅有所改善，但红光则不然。在50英尺行走期间，与红光和无光束相比，使用绿光时冻结发作次数减少。在360°转弯期间，与红光和无光束相比，使用绿光时时间、步数和冻结发作次数减少。在“开”药期间，与红光相比，绿光使步态速度和步幅改善得更多。在两种药物状态下，两种颜色对步频均无影响。
结论
与红光或无光束相比，绿光能更好地改善PD患者的步态并减轻FOG。
