Study Details

Brief summary:

The goal of this clinical trial is to learn if chiropractic ankle manipulation can improve squat jump performance. It will also learn about the relationship among chiropractic ankle manipulation, ankle range of motion, and squat jump performance. The main questions it aims to answer are:

  • Does chiropractic ankle manipulation increase squat jump height?
  • Is there a relationship among chiropractic ankle manipulation, ankle range of motion, and squat jump performance?

Researchers will compare squat jump performance between subjects who receive chiropractic ankle manipulations with control subjects to see if ankle chiropractic manipulation works to improve squat jump performance.

Participants will:

  • Visit the research laboratory for one testing session to measure ankle range of motion and squat jump performance, before and after their randomly assigned intervention arm
  • Receive either a chiropractic ankle manipulations or rest quietly as the control condition during the testing session.

Interventions and Outcome Measures

Arms

experimental: Chiropractic Ankle Manipulation

LEM - Lower Extremity Manipulation:

Subjects assigned to the LEM Intervention Group will receive a short lever, high velocity, low-amplitude distractive (caudal) thrust directed at the talocrural joint. The treating chiropractor will deliver the LEM to the right ankle then the left ankle. LEM is an adjustment for long axis distraction of the tibiotalar joint with the goal to improve dorsiflexion of the ankle joint.

no intervention: Control

Subjects assigned to the Control Group will rest quietly, supine (face up), on the chiropractic treatment table for five (5) minutes.

Interventions

Manual Therapy Procedure: Chiropractic Ankle Manipulation

The lower extremity manipulation (LEM) procedure is a short lever, high velocity, low-amplitude distractive (caudal) thrust directed at the talocrural joint. The treating chiropractor will deliver the LEM to the right ankle then the left ankle. LEM is an adjustment for long axis distraction of the tibiotalar joint with the goal to improve dorsiflexion of the ankle joint.

Primary outcome measure

  • Squat Jump Height [ Time Frame: Baseline on Day 1 to Immediately after Intervention on Day 1 ]
  • Range of Motion of Ankle Dorsiflexion [ Time Frame: Baseline on Day 1 to Immediately after Treatment on Day 1 and at End of Test Session on Day 1 ]
