Limited Ankle Dorsiflexion and Effect on Single Limb Squats in Individuals With Patellofemoral Pain

Loma Linda University

Start Date

3/2/2022

Completion Date

5/1/2026

Summary

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.

Detailed Description

1. 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. 2. Participants will complete two self-reported questionnaires on how their diagnosis affects functional activities. 3. Dorsiflexion range of motion in a weight bearing position will be taken. 4. Hip abductor strength on tested limb will be measure on isokinetic device. 5. 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. 6. 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. 7. Each participant will then have their dorsiflexion measured again prior to completing another 3 trials of the Lateral Step Down test.
