Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Primary Intervention Group

The experimental group will receive two interventions to increase dorsiflexion range of motion.

Group Type EXPERIMENTAL

Mobilization with Movement

Intervention Type OTHER

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.

Minimal Intervention Group

The minimal intervention group will read and infographic and complete 5 minutes of treadmill walking.

Group Type ACTIVE_COMPARATOR

No mobilization with movement and education

Intervention Type OTHER

Participants ankle will not be taped and they will walk on the treadmill for 5 minutes and receive education.
