Study 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.

Read the 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.

Study arms

  • Experimental
    Primary Intervention Group

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

    Other: Mobilization with Movement

  • Active comparator
    Minimal Intervention Group

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

    Other: No mobilization with movement and education

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.

What researchers measure

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.

    Time frame: change between baseline and post intervention on Day 1

Secondary outcomes

  1. 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.

    Time frame: change between baseline and post intervention on Day 1

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Mar 2022 (actual). Primary completion is estimated for May 2027, 62 months after the start.

Of 153 non-industry interventional studies with no phase under Patellofemoral Pain Syndrome, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 4 and three quarters within 20. This study's planned 62 months is above that.

Counting every sponsor, half of 157 studies reached it within 11 months; a quarter within 4 and three quarters within 21.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 20, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
