The purposes of this study is to determine: (a) the relationship between the dependant variables, (b) the relationship between the Borg pain scale and the performance tests, (c) the difference in performance between involved and uninvolved extremities, and (d) the effects of the three different therapeutic exercise treatments on selected performance tests and pain free isometric strength testing. Fifty subjects with physician diagnosed anterior knee pain (AKP), completed initial performance testing and 14 subjects completed initial testing, therapy and six weeks later final performance testing. The 14 subjects were randomly assigned to one of three therapeutic exercise treatment groups. The performance tests included; pain free isometric strength tests (90, 60, 45, and 15 degrees knee flexion), stair test, timed hop, triple hop, crossover hop, Figure 8 and Borg pain scale rating for each performance test. The results indicated a significant correlation between performance tests and pain free isometric strength tests. There was no relationship indicated between the performance tests, Borg pain scale ratings. The contrast between the injured and uninjured extremities performance test values of the fifty subjects that completed the initial testing indicated no significant (p< 0.05) difference. The results of this study indicated that there was no significant difference between the therapeutic exercise treatment groups. In conclusion, the three anterior knee pain treatments had no effect on strength and performance.
