It will also explore whether these techniques affect athletes' perception of movement fluency and sport-specific performance.\n\nThe main questions it aims to answer are:\n\nDoes Floss Band application immediately improve shoulder range of motion in volleyball athletes? Does Floss Band application change the perception of movement fluency compared to MWM? Does Floss Band application impact sport-specific performance tests compared to MWM?\n\nParticipants will:\n\nBe randomly assigned to receive either Floss Band or mobilization with movement Have their shoulder mobility, perception of movement, and sport performance tested before and immediately after the intervention", 'detailedDescription': "Overhead sports such as volleyball demand repetitive, high-velocity arm movements that predispose athletes to musculoskeletal adaptations, especially in the glenohumeral joint. Among these, glenohumeral internal rotation deficit (GIRD) is a frequent finding, typically associated with posterior capsular tightness and muscular adaptations. This condition has been linked to decreased shoulder performance and a greater risk of overuse injuries.\n\nConservative approaches are essential for preserving mobility and reducing injury risk in overhead athletes. Mobilization with movement (MWM) is a well-established manual therapy intervention, combining therapist-applied accessory glenohumeral mobilization with the athlete's active shoulder motion. Evidence supports its capacity to produce immediate improvements in range of motion and sensorimotor control.\n\nIn contrast, the use of compressive elastic bands, or Floss Bands, represents a more recent strategy in rehabilitation. Proposed mechanisms include transient ischemia followed by reperfusion, improved soft tissue gliding, neuromuscular activation, and increased proprioceptive input. Although Floss Band applications have gained popularity, robust evidence on their effects in overhead athletes is still limited.\n\nThe current randomized, controlled, double-blind equivalence trial aims to compare the immediate effects of Floss Band application with MWM on shoulder mobility in volleyball athletes. The equivalence design was selected because both interventions are hypothesized to provide similar clinical benefits, and the study seeks to determine whether the novel approach (Floss Band) is not inferior to the well-established MWM.\n\nIntervention Procedures Participants will undergo two assessments: baseline and immediately post-intervention. Interventions will be delivered by researchers trained and standardized in both techniques.\n\nFloss Band Group (FBG): The participant will be seated with the shoulder positioned at 90° abduction. The researcher will apply a compressive elastic band (100% polymer gel, 210 cm circumference, 5 cm width, 1.3 mm thickness). The first anchor will be placed two finger-widths medial to the acromion, and the band will be wrapped circumferentially around the shoulder until the material length is exhausted, securing the final anchor. During the two-minute application, the participant will perform sport-specific movements (e.g., spike and serve gestures). After the time limit, the band will be removed.\n\nMobilization with Movement Group (MWM): The participant will remain seated with back support and hips, knees, and ankles flexed at 90°. The therapist will stabilize the scapula with one hand, while the other hand will apply a posterolateral glide to the humeral head during active arm elevation in the scapular plane. The protocol will consist of three sets of 10 repetitions, with one-minute rest intervals between sets.\n\nData Management and Quality Assurance All assessors will undergo standardized training to ensure consistency across evaluations. Prior to trial initiation, pilot testing of procedures will be conducted. Data will be collected using predefined case report forms and transferred into a secure electronic database.\n\nQuality assurance measures will include:\n\nData validation: Automated checks for range, completeness, and logical consistency between variables.\n\nSource data verification: Cross-checks of electronic entries with original case report forms by an independent monitor.\n\nAuditing: Periodic audits conducted by external staff not involved in data collection or intervention delivery.\n\nStandard Operating Procedures (SOPs): Detailed instructions for participant recruitment, intervention delivery, data entry, adverse event reporting, and change management.\n\nData dictionary: Comprehensive description of variables, coding schemes, and reference values to maintain consistency and transparency.\n\nSample Size and Statistical Plan The trial is powered to detect equivalence between interventions in the primary outcome (shoulder ROM). A total of 36 athletes will be randomized equally across groups, stratified by sex and age. Analyses will follow the intention-to-treat principle. Between-group differences will be adjusted for baseline values, and 95% confidence intervals will be calculated to test equivalence margins. Missing data will be addressed with multiple imputation methods.\n\nExpected Contribution By comparing an innovative compressive technique with an established manual therapy, this study is designed to provide high-quality evidence on immediate intervention effects in volleyball athletes. The results are expected to inform clinicians, coaches, and sports medicine professionals on effective strategies for optimizing shoulder function and preventing injury in overhead sports."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT'], 'maximumAge': '50 Years', 'minimumAge': '18 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* Age between 18 and 50 years.\n* Male or female volleyball athletes (indoor or beach), at amateur or professional level.\n* Regular training routine of at least two sessions per week.\n* No shoulder pain at the time of testing or during the previous three months.\n\nExclusion Criteria:\n\n* History of shoulder surgery, structural shoulder injuries (e.g., fractures, labrum tear), or recurrent glenohumeral dislocation.\n* 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.\n* 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.\n* 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.\n* Development of shoulder or elbow injuries during the study, especially requiring surgical intervention.\n* Participants who voluntarily withdraw from the study at any time.'}, 'identificationModule': {'nctId': 'NCT07192003', 'briefTitle': 'Immediate Effects of Flossband and Mobilization With Movement on Shoulder Mobility in Volleyball Athletes', 'organization': {'class': 'OTHER', 'fullName': 'Federal University of Paraíba'}, 'officialTitle': 'Comparison of the Immediate Effect of Flossband and Mobilization With Movement on Shoulder Mobility in Volleyball Athletes: A Randomized Clinical Trial', 'orgStudyIdInfo': {'id': '7812025'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'Mobilization with Movement (MWM) Group', 'description': 'Participants in this arm will perform the standardized Mobilization with Movement (MWM) protocol.
