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.
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
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
Parallel
Mobilization with Movement
Other interventionParticipants 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.
No mobilization with movement and education
Other interventionParticipants ankle will not be taped and they will walk on the treadmill for 5 minutes and receive education.
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.
Patellofemoral Disability Index
The Index is a self-reported questionnaire that addresses the amount of pain a person may have during tasks such as running, jumping, and stair climbing.
