Clinical Trial: Oscillatory dumbbell training outperforms shoulder mobilization for improving strength, proprioception, and function in female swimmers with impingement syndrome: a randomized controlled trial (Japan)

Tokyo, May 24 -- UMIN Clinical Trials Registry (UMIN-CTR) received information related to the study (UMIN000061624) titled 'Oscillatory dumbbell training outperforms shoulder mobilization for improving strength, proprioception, and function in female swimmers with impingement syndrome: a randomized controlled trial' on May 24.

Study Type: Interventional

Study Design: Basic Design - Parallel Randomization - Randomized Blinding - Single blind -investigator(s) and assessor(s) are blinded Control - No treatment

Primary Sponsor: Institute - Self funding

Condition: Condition - pre-post-follow up Classification by malignancy - Others Genomic information - NO

Objective: Narrative objectives1 - The primary objective of this randomized controlled trial was to compare the immediate and one week (retention) effects of a single session of oscillatory dumbbell training versus shoulder mobilization on shoulder rotator cuff strength, proprioception, and upper quarter function in female swimmers diagnosed with subacromial impingement syndrome. A secondary objective was to determine whether any between group differences observed immediately after the intervention would persist for one week. Basic objectives2 - Safety,Efficacy

Intervention: Interventions/Control_1 - Oscillatory Dumbbell Training (ODT) Interventions/Control_2 - Shoulder Mobilization (MOB)

Eligibility: Age-lower limit - 20 years-old = Gender - Female Key inclusion criteria - Eligible participants were female competitive or recreational swimmers aged between 18 and 35 years who had a clinical diagnosis of subacromial impingement syndrome of the dominant shoulder. The diagnosis was confirmed by a sports medicine physician based on the presence of a painful arc during shoulder abduction between 60 and 120, tenderness on palpation of the rotator cuff tendons, and a positive Hawkins Kennedy impingement test. Additionally, participants were required to have at least 130 of active shoulder abduction in the frontal plane and to have been swimming regularly for a minimum of one year with at least three training sessions per week. All participants provided written informed consent, and those under 18 years of age also provided parental consent. Key exclusion criteria - Potential participants were excluded if they had a history of traumatic shoulder dislocation, fracture, or surgery involving the shoulder joint, or any evidence of full thickness rotator cuff tear, glenohumeral instability, or labral pathology confirmed by physical examination or imaging. Other exclusion criteria included scapular dyskinesis or thoracic kyphosis diagnosed by a physiatrist, cervical radiculopathy or other neurological disorders affecting the upper extremity, rheumatic diseases or degenerative joint changes, and any history of corticosteroid injection or physiotherapy targeting the shoulder or neck within the past six months. Individuals with skin conditions over the shoulder or scapular region, those who were unwilling to comply with the study protocol, and those with any contraindication to manual therapy or vibration exercise were also excluded. Target Size - 90

Recruitment Status: Recruitment status - Preinitiation Date of protocol fixation - 2026 Year 05 Month 01 Day Date of IRB - 2026 Year 02 Month 19 Day Anticipated trial start date - 2026 Year 05 Month 04 Day Last follow-up date - 2026 Year 05 Month 13 Day
