The purpose of this study was to investigate the change of pain degrees, range of motions, in 12 adult men with patellofemoral pain syndrome and grade Ⅰ or Ⅱ laxity after applying the complex training. 1. Before the complex training, the pain degrees felt at the knee involved side were 4.2±0.49, which showed between "very server" and "unbearable". But it decreased after the complex training. The 2nd(3.8±0.63), 5th(3.2±0.63), 6th(2.6±1.07), 7th(2.0±0.81), and 8th(1.4±0.51)weeks were significantly decreased. The pain degree in last week was presented "no or mild pain" (p＜.001). 2. Before the complex training, the range of motion of the knee involved side was 105.2±6.67˚, with was different in normal ROM(about 139˚). But it increased after the complex training. All of the ROM in each week were significantly increased. Especially. The ROM in last week was presented 138.6±2.48˚(p＜.001).
