Musculoskeletal Injuries, Pelvic Floor Dysfunctions and Menstrual Irregularities in Norwegian Rhythmic Gymnasts and Dancers - Observational and Cluster Randomized Controlled Studies
In Brief
A clinical study evaluating Exercises for knees, lower back, hip/groin and pelvic floor muscles in an expanded warm up program for Overuse Injury and Urinary Incontinence. Completed, enrolled 205 participants across 1 site.
Detailed Summary
Overuse injuries are common among competitive Norwegian rhythmic gymnasts with a mean weekly prevalence of 37% \[95% CI: 36 - 39%\] and incidence of 4.2 new overuse injuries \[95% CI: 3.6 - 4.9\] per gymnast per year (Gram, M., Clarsen, B., \& Bø, K., 2021). The knees, lower back and hip/groin were the most common injury locations. It has been postulated that reduced physical capacity (e.g strength, flexibility, stability) in the knees, lower back and hip/groin can increase the risk of injuries in rhythmic gymnastics. In addition, more than 30% of the Norwegian rhythmic gymnasts experience urinary incontinence (UI), and 70% reported that UI negatively affected sports performance (Gram, M., \& Bø, K., 2020). Few of the rhythmic gymnasts had any knowledge about the pelvic floor. Hence, this assessor blinded cluster randomized controlled trial aims to find out whether the implementation of exercises targeting reduced physical capacity and pelvic floor dysfunction can prevent/reduce the prevalence of overuse injuries and UI.

Interventions
Rhythmic gymnastics clubs allocated to the intervention group will be visited by a physiotherapist (the PhD candidate), which will perform thorough teaching of coaches and gymnasts on how to perform the exercises in the expanded warm up program. During the same visit, before commencing PFMT, the gymnasts will have an individual session were a portable 2D ultrasound machine (GE Healthcare -Logiq e R7, GE\>12L-RS - 5-13 MHz Wideband Linear Probe) will be used to teach and assess ability to perform a correct PFM contraction. The probe is placed suprapubically and provides concurrent visible biofeedback of the PFM contraction. Adherence to the intervention will be registered weekly by the coach in a training diary and asked for as an additional question in the monthly OSTRC-H2 sent to the gymnasts. Reminders will be sent by phone to the coaches every week. To assure proper execution and motivation, the PhD candidate will perform one extra visit midterm.
