Shoulder Pain, Volleyball Players
Conditions
Brief summary
Shoulder pain can be common in overhead sports, and in particular, in volleyball. Different physiotherapy protocols can be adopted depending on the suspected pathophysiological mechanisms. Despite most of the protocols rely only on the shoulder district, some research suggests that treating the whole-body might produce better results as it could influence kinematic chains and correct muscle imbalances. The aim of this study will be to compare the effects of two physiotherapy protocols (shoulder focus or whole body) compared to only education without physiotherapy.
Interventions
This intervention consists in 5 weeks of 2 x week 60 min sessions of physiotherapy consisting in active exercise performed in upper limb, trunk, and lower limb muscles, in a whole-body approach.
This intervention consists in 5 weeks of 2 x week 60 min sessions of physiotherapy consisting in active exercise performed only in the shoulder district, focusing on the trunk-arm muscles.
Single education session providing information about posture hygiene and proper warm-up

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Isometric strength with handheld dynamometer (Newtons) | At enrollment and at the end of treatment at 5 weeks | Isometric strength during shoulder flexion, extension, external and internal rotation, bilaterally |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Lateral symmetry (%) | At enrollement and at the end of treatment after 5 weeks | Lateral symmetry will be assessed as percentage between the two upper limbs for the investigated muscles (pectoralis major, latissimus dorsi, upper trapezius, middle trepezius, lower trapezius, anterior deltoid, posterior deltoid) using the tensiomyography system |
| Time of contraction (ms) | At enrollement and at the end of treatment after 5 weeks | Time of contraction (ms), i.e. the time requiring the muscle to reach the peak of muscle displacement, will be assessed as percentage between the two upper limbs for the investigated muscles (pectoralis major, latissimus dorsi, upper trapezius, middle trepezius, lower trapezius, anterior deltoid, posterior deltoid) using the tensiomyography system |
| Muscle belly displacement (mm) | At enrollement and at the end of treatment after 5 weeks | Muscle belly displacement (mm), i.e. the amplitude of muscle displacement, will be assessed as percentage between the two upper limbs for the investigated muscles (pectoralis major, latissimus dorsi, upper trapezius, middle trepezius, lower trapezius, anterior deltoid, posterior deltoid) using the tensiomyography system |
