Descrição detalhada
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

Grupo de Participantes / Braço |
Intervenção / Tratamento |
|---|---|
|
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.
|
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.
|
|
Comparador Falso: 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.
|
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.
