CONTEXT: Gluteus medius (Gmed) is proposed to consist of three functional subdivisions (anterior, middle and posterior). Weakness and dysfunction of Gmed has been implicated in numerous lower extremity disorders, including patellofemoral pain syndrome (PFPS). PFPS is a knee condition which frequently occurs in females and is associated with activities such as squatting and stair climbing. There is a lack of existing evidence examining the role of the subdivisions of Gmed in females with and without PFPS. OBJECTIVE: To compare muscle activation in the three Gmed subdivisions during four weight-bearing exercises in females with and without PFPS. DESIGN: Single session, repeated measures observational study. SETTING: University research laboratory. PARTICIPANTS: Convenience sample of 12 females with PFPS and 12 age- and gender-matched asymptomatic controls. INTERVENTION: Participants performed four weight-bearing exercises (wall press, pelvic drop, step-up-and-over and unilateral squat) three times while surface electromyography (sEMG) activity of the Gmed segments was recorded. MAIN OUTCOME MEASURES: sEMG muscle activity for each functional subdivision of Gmed during each weight-bearing exercise was analysed using a mixed between-within subjects ANOVA (post-hoc Bonferroni). RESULTS: No statistically significant differences in muscle activation were found between the PFPS and healthy participants (p=0.97). Furthermore, there were no statistically significant differences between the exercises (p=0.19) or muscle fibres (p=0.36) independent of group analysed. However, the activation of the subdivisions varied according to the exercises performed (p=0.003). CONCLUSIONS: Similar levels of muscle activation were recorded in the Gmed subdivisions of the PFPS and healthy participants during the different exercises. This is the first study to examine all three Gmed subdivisions in PFPS. Future studies using larger sample sizes should also investigate onset and duration of muscle activation in all Gmed subdivisions in both PFPS and healthy individuals. |
