Brief 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.

Conditions

Patellofemoral Pain

Outcome Measures

Primary Outcomes (1)

• Weight bearing lunge test

  This test is used to assess a participant's available dorsiflexion range of motion in a weight bearing position. Furthermore, this places the participants hip, knee, and ankle into a flexed position which correlates with the squat tests we will be using.

Secondary Outcomes (1)

• Patellofemoral Disability Index

  change between baseline and post intervention on Day 1

Study Arms (2)

Primary Intervention Group

EXPERIMENTAL

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

Other: Mobilization with Movement

Minimal Intervention Group

ACTIVE COMPARATOR

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

Other: No mobilization with movement and education

Interventions

No mobilization with movement and education OTHER

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

Minimal Intervention Group

Mobilization with Movement 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.
