Girls aged 12-18 years, either with knee pain for at least 2 months, or with NO history of lower leg pain are needed for our study.
The study will determine if adolescents with knee pain control their knee muscles differently to those without knee pain.
We hope to identify a target for future treatment options for adolescents with knee pain. Data collection includes an MRI, ultrasound, and measurements of muscle activity. Data collection will take 2-3 hours total.
