Immediate Effects of Ankle Joint Mobilization on Jump Performance in Healthy University Students

July 14, 2026 updated by: Burhan Taşkaya, Muş Alparslan University

Immediate Effects of Ankle Joint Mobilization on Countermovement Jump Performance and Dorsiflexion Range of Motion in Healthy University Students

The purpose of this randomized controlled study is to investigate the immediate effects of ankle joint mobilization on countermovement jump performance and ankle dorsiflexion range of motion in healthy university students. Participants will be randomly assigned to either an ankle joint mobilization group or a sham mobilization group. Countermovement jump performance will be assessed using the My Jump Lab mobile application, and ankle dorsiflexion range of motion will be measured using the weight-bearing lunge test with a digital inclinometer before and immediately after the intervention. The findings of this study are expected to improve the understanding of the acute effects of ankle joint mobilization on functional performance and ankle mobility.

Detailed Description

Vertical jump performance is an important indicator of lower-extremity explosive power and neuromuscular function. Adequate ankle dorsiflexion range of motion plays a critical role in force production, movement efficiency, and landing mechanics during jumping tasks. Previous studies have demonstrated that ankle joint mobilization can improve dorsiflexion range of motion through mechanical and neurophysiological mechanisms. However, limited evidence exists regarding whether these immediate improvements in ankle mobility translate into enhanced jump performance in healthy individuals.

This randomized controlled study aims to evaluate the immediate effects of ankle joint mobilization on countermovement jump performance and ankle dorsiflexion range of motion in healthy university students.

Approximately 50 healthy university students will be recruited and randomly allocated to either an ankle joint mobilization group or a sham mobilization group (25 participants per group). Before the intervention, all participants will undergo assessments of countermovement jump performance using the My Jump Lab mobile application and ankle dorsiflexion range of motion using the weight-bearing lunge test with a digital inclinometer.

Participants in the intervention group will receive ankle joint mobilization using the Mobilization with Movement (MWM) technique. Participants in the sham group will be positioned similarly and perform the same movement without the application of therapeutic posterior talar glide. Immediately after the intervention, all outcome measures will be repeated using the same standardized procedures.

The primary outcome will be countermovement jump performance, while the secondary outcome will be ankle dorsiflexion range of motion. The results of this study may provide evidence regarding the immediate effects of ankle joint mobilization on functional performance and may contribute to the development of evidence-based manual therapy interventions for improving lower-extremity performance

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Mobilization with Movement (MWM)
Participants assigned to this group will receive ankle joint mobilization using the Mobilization with Movement (MWM) technique. A sustained posterior talar glide will be applied while participants actively perform a weight-bearing lunge movement. The intervention will consist of three sets of ten repetitions, with a 2-3 second hold at the end range of each repetition.
Procedure: Mobilization with Movement (MWM)
A Mulligan Mobilization with Movement technique will be applied to the talocrural joint. During active weight-bearing lunge movement, a sustained posterior talar glide will be applied by the therapist. The intervention will consist of three sets of ten repetitions.
Sham Comparator: Sham Mobilization
Participants assigned to this group will undergo the same positioning and active weight-bearing lunge movement as the experimental group. However, no therapeutic posterior talar glide will be applied. This procedure is designed to mimic the intervention without providing a therapeutic mobilization effect.
Procedure: Sham Mobilization
Participants will perform the same active movement in the same position as the experimental group. The therapist will maintain hand contact without applying a therapeutic posterior talar glide.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Countermovement Jump Performance
Time Frame: Immediately before the intervention and immediately after the intervention (single session).
Countermovement jump (CMJ) performance will be assessed using the My Jump Lab mobile application. Participants will perform three maximal countermovement jumps with their hands on their hips, and the highest jump height (cm) will be recorded.
Immediately before the intervention and immediately after the intervention (single session).

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Ankle Dorsiflexion Range of Motion
Time Frame: Immediately before the intervention and immediately after the intervention (single session)
Ankle dorsiflexion range of motion will be measured using the weight-bearing lunge test with a digital inclinometer. Three measurements will be obtained, and the average value (degrees) will be used for analysis.
Immediately before the intervention and immediately after the intervention (single session)
