Overview
The purpose of this graduate student research study is to investigate the relationship between limited ankle dorsiflexion and the potential effects on a single limb squat task in the Patellofemoral/Knee Pain population.
Description
- Participants will undergo Covid screening prior to filling out consent form and PHI. Randomization will occur to create an experimental group and a minimal intervention group.
- Participants will complete two self-reported questionnaires on how their diagnosis affects functional activities.
- Dorsiflexion range of motion in a weight bearing position will be taken.
- Hip abductor strength on tested limb will be measure on isokinetic device.
- The Lateral Step Down test will be conducted for 6 trials on each participant, 3 with a heel wedge and 3 without, movement recorded, and graded using two motion capture devices.
- The experimental group will receive two interventions to increase dorsiflexion range of motion. The minimal intervention group will read and infographic and complete 5 minutes of treadmill walking.
- Each participant will then have their dorsiflexion measured again prior to completing another 3 trials of the Lateral Step Down test.

Exclusion Criteria:
- History of musculoskeletal surgery or fractures on the tested leg or lumbar spine that could affect their biomechanics during the study
- History of soft tissue or skeletal abnormalities in the tested limb
