About this study
Official title: Investigation of the Effect of Activator-Assisted Talocrural Joint Manipulation on Acute Sports Performance Parameters in Elite Male Volleyball Players
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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Sham StrokingOther
Also called Non-therapeutic light touch technique
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.
Activator ManipulationOther
Also called Activator Adjustment Instrument (AAI)
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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Ankle Range of Motion (Plantar/Dorsiflexion)
Plantar and dorsiflexion measured using a goniometer (degrees).
Measured: Pre-intervention (T0) and post-intervention (T1, within 3-5 minutes).
Y-Balance Test
Anterior, posteromedial, and posterolateral reach distances (cm).
Measured: Pre-intervention (T0) and post-intervention (T1, within 3-5 minutes).
Jumping Performance:
Vertical jump height and horizontal jump distance (cm).
Measured: Pre-intervention (T0) and post-intervention (T1, within 3-5 minutes).
Dynamic Weight Transfer
Assessed via pedobarographic analysis, including static load ratio (%), dynamic contact area ratio (CAR-AP, CAR-RP, %), and dynamic speed (mm/s).
Measured: Pre-intervention (T0) and post-intervention (T1, within 3-5 minutes).

Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07072260, which also lists 1 linked publication.
