This systematic review and meta-analysis was accomplished
to determine whether exercise therapy is an effective intervention to reduce pain
and patient-reported measures of activity limitations and participation
restrictions (PRMALP) in patients with patellofemoral pain.
STUDY SELECTION: Randomized controlled trials in English and German languages
published in the MEDLINE, Physiotherapy Evidence Database (PEDro), International
Clinical Trials Registry Platform, and Cochrane databases were searched.
Eligibility was assessed in 2 stages. The methodological quality of the studies
was rated using the PEDro scale. Data were pooled using random-effects
meta-analysis, allowing for variability among studies. For clinical use, overall
estimates were re-expressed in the original visual analog scale scores.
Significance was set at 5%. DATA EXTRACTION AND DATA SYNTHESIS: Fifteen studies,
with a total of 748 participants, were included and pooled for the meta-analysis.
Six studies compared the effect of exercise therapy with a control group
receiving neither exercise therapy nor another intervention. Four studies
compared the effect of exercise therapy versus additive therapy, and 5 studies
compared different exercise interventions. In both comparisons, exercise therapy
resulted in strong pain reduction and improvement of PRMALP effects. Significant
short-term effects (</=12 weeks) of exercise therapy were found for pain and
PRMALP, whereas long-term effects (>/=26 weeks) were observed for PRMALP only.
LIMITATIONS AND CONCLUSION: The 15 studies included in this analysis were of
variable quality. Large-scale, high-quality randomized controlled trials are
needed to further the evaluation of the possible effects of different exercise
therapy modalities on patellofemoral pain. This meta-analysis presents evidence
that exercise therapy has a strong pain-reducing effect and decreases PRMALP in
patients with patellofemoral pain. However, the question of which exercise modality yields the strongest reducing effect on pain and PRMALP remains
unanswered.
