Abstract

Purpose: To investigate the influence of additional eccentric strengthening to the hip abductor and lateral rotator musculature on pain and function in sedentary people with Patellofemoral pain syndrome (PFPS).

Methods: 30 sedentary patients between 18 and 40 years of age, with a diagnosis of PFPS, all the subjects received treatment for a period of 4weeks and the subjects were randomly assigned to Control group (CG) and Experimental group (EG). The patients in the Control group (n = 15) performed a conventional knee-stretching and strengthening program, whereas, patients in the Experimental group (n = 15) performed the same exercises as those in the control group ,in addition received eccentric strengthening exercises for the hip abductors and lateral rotators. An 11-point numeric pain rating scale (NPRS), the Lower Extremity Functional Scale (LEFS) and the Anterior Knee Pain Scale (AKPS) were used as outcome measures during the baseline and at the end of 4weeks .

Results: Statistics were retrieved using SPSS.16, paired 't' test was conducted to compare AKPS and LEFS values ,whereas, Mann- Whitney U test was used for NPRS value between the groups. After 4 weeks of treatment, the control group, pre and post-test value for AKPS (p<0.001),LEFS (P<0.001),NPRS (p<0.001) shows a statistical significance and even in the experimental group, pre and post-test value for AKPS (p<0.001),LEFS (P<0.001),NPRS (p<0.001) shows a statistical significance in pain and function, but comparing both the group experimental group is significantly more better AKPS (p=0.002),LEFS (P<0.001),NPRS (P<0.001) then a control group.

Conclusion: short term Knee strengthening exercises supplemented by eccentric hip abductor and lateral rotator musculature–strengthening exercises were more effective than knee exercises alone in improving function and reducing pain in sedentary people with PFPS.
