Limited Ankle Dorsiflexion and Effect on Single Limb Squats in Individuals With Patellofemoral Pain: Interventions and Outcomes in a Randomized Clinical Trial
Loma Linda University
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.
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 usi…

Inclusion Criteria: * History of active Patellofemoral Pain for at least 6 months * No clinic based therapeutic interventions for a 6-month period prior to testing * Females aged 18-59 years' old * Limited ankle dorsiflexion as noted by \<45degs using the weight bearing lunge 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 * Current knee effusion * Resting pain greater than 5/10
Interventions
- OtherMobilization with Movement
Participants will be lunging on a box with posterior ankle glide of 10 seconds times 5 sets. They will have 30 seconds rest between trials. Participant will have their ankle taped and then walk on a treadmill at a self-selected pace for 5 minutes.
- OtherNo mobilization with movement and education
Participants ankle will not be taped and they will walk on the treadmill for 5 minutes and receive education.
