Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This randomized controlled trial aims to evaluate the acute effects of activator-assisted talocrural joint manipulation on joint range of motion, dynamic balance, vertical and horizontal jump performance, and weight transfer parameters in elite male volleyball players aged 18-25. The study compares a manipulation group with a sham control group and assesses performance metrics before and after the intervention.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Activator-Assisted Talocrural Manipulation

Participants in this group receive a single session of activator-assisted manipulation using the Activator Adjustment Instrument (AAI) to the talocrural (ankle) joint. Six impulses (three anterior and three posterior) are applied with the ankle in a neutral position.

Group Type EXPERIMENTAL

Activator Manipulation

Intervention Type OTHER

Participants in this group receive a single session of activator-assisted manipulation using the Activator Adjustment Instrument (AAI) to the talocrural (ankle) joint. Six impulses (three anterior and three posterior) are applied with the ankle in a neutral position.

Sham Soft Tissue Stroking

Participants in this group receive a sham intervention consisting of light soft tissue stroking around the talocrural joint without joint manipulation. The application mimics the duration and setup of the experimental group but does not include any mechanical stimulus.

Group Type SHAM_COMPARATOR

Sham Stroking

Intervention Type OTHER

Participants in this group receive a sham intervention consisting of light soft tissue stroking around the talocrural joint without joint manipulation. The application mimics the duration and setup of the experimental group but does not include any mechanical stimulus.
