Volleyball players: can a simple band boost your shoulder mobility instantly?
NCT ID NCT07192003
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a floss band or a hands-on movement technique can immediately improve shoulder mobility in volleyball athletes. Thirty-six amateur or professional players will be randomly assigned to one of the two methods. Their shoulder range of motion, movement fluency, and sport performance will be measured before and right after the intervention.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Floss Band (compressive elastic band) and mobilization with movement (MWM) procedure
- What this could lead to
- If it works, this could point toward a quick, non-drug way for volleyball players to improve shoulder mobility and performance before games or training.
- What could go wrong
- This is a small, early-stage trial with only 36 healthy athletes, so results may not apply to others. It only looks at immediate effects, not long-term benefits or injury prevention.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: * Age between 18 and 50 years. * Male or female volleyball athletes (indoor or beach), at amateur or professional level. * Regular training routine of at least two sessions per week. * No shoulder pain at the time of testing or during the previous three months. Exclusion Criteria: * History of shoulder surgery, structural shoulder injuries (e.g., fractures, labrum tear), or recurrent glenohumeral dislocation. * Skin disorders contraindicating the intervention, including active dermatitis, inflammatory-phase psoriasis, cutaneous infections (e.g., folliculitis), open wounds, burns, eczema, or hypersensitivity in the shoulder region. * Vascular disorders contraindicating the intervention, including history or diagnosis of deep vein thrombosis, symptomatic varicose veins, peripheral arterial disease, lymphedema, or advanced chronic venous insufficiency. * Other conditions contraindicating intervention: peripheral neuropathies with significant sensory loss, presence of a pacemaker in the region of band application, known allergy to elastic band material, or pain during shoulder movement at assessment. * Development of shoulder or elbow injuries during the study, especially requiring surgical intervention. * Participants who voluntarily withdraw from the study at any time.
