About

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.

Enrollment: 60 estimated patients

Sex: All

Ages: 18 to 35 years old

Volunteers: Accepts Healthy Volunteers

60 participants in 2 patient groups

Chiropractic Ankle Manipulation

Experimental group

Description:

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.

Treatment:

Other: Manual Therapy Procedure: Chiropractic Ankle Manipulation

Control

No Intervention group

Description:

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