| Abstract | ||
| Aims: Patellofemoral Pain Syndrome (PFPS) is a term used to describe various pathologies or anatomical abnormalities that result in anterior knee pain and is one of the most common causes of such pain. The present study aims first to extract the muscle synergies of individuals with and without PFPS during walking and subsequently analyze and compare their synergy patterns and corresponding activation coefficients throughout the gait cycle. Methods: The statistical population of the present study consisted of adults aged 25 to 35 years, including two groups: a healthy group (12 individuals) and a group with patellofemoral pain syndrome (9 individuals). This study was designed using a force plate, motion analysis system, and EMG, based on specific inclusion and exclusion criteria. Data were analyzed using specialized software and statistical methods such as HALS, frequency analysis, and t-tests. Findings: Results no significant difference in the number of muscle synergies and the contribution of each lower limb muscle in the extracted synergies between the control and affected groups (p ≤ 0.05). Conclusion: This pioneering study in Iran investigated muscle synergies during walking in individuals with patellofemoral pain syndrome and revealed distinct neural control patterns, although no significant changes were observed in the structure of the synergies. The lack of statistical significance may be attributed to the limited sample size and variations in measurement methods, highlighting the importance of targeted rehabilitation considering the impact of this condition on balance.
