Objectives : To assess trunk, knee, and ankle muscle balance in hip-hop dancers to support injury prevention

Design: A cross-sectional descriptive study was conducted at the Department of Physical and Rehabilitation Medicine, at the Mohammed VI University Hospital of Marrakech, from January to December 2023, including 30 local hip-hop dancers. Each underwent OSTRC (Oslo Sports Trauma Research Centre) injury screening and isokinetic testing at 30°/s–60°/s on trunk, knee, and ankle joints.

Results: The mean age was 26.7 years, with a male predominance (63%) and mean BMI 22.56. The most frequent pain sites were the lower back (73%), knees (53%), and ankles (40%). Isokinetic testing revealed muscle imbalances in 83% of knees, 76.7% of trunks, and 63% of ankles. No significant correlation was found between imbalance and dance style, but age was significantly associated with injury risk (p = 0.010).

Conclusion: Isokinetic assessment combined with OSTRC monitoring should be integrated into dancers’ routine follow-up to detect imbalances early and implement targeted strengthening programs for lumbar extensors and hamstrings to prevent injuries and prolong career longevity
