Home-Based Corrective Exercise With Remote Reinforcement for Upper Crossed Syndrome
Effects of a Home-Based Corrective Exercise Program With Active Remote Reinforcement on Craniovertebral Angle, Rounded Shoulder Posture, Thoracic Kyphosis, Pain, Cervical and Shoulder Disability, and Pulmonary Function i Adults With Upper Crossed Syndrome: A Two-Arm Parallel Randomized Controlled Trial
Upper Crossed Syndrome (UCS) is a musculoskeletal condition defined by simultaneous forward head posture (craniovertebral angle, CVA < 52°), rounded shoulders (RSP > 52°), and thoracic hyperkyphosis (> 42°). It is highly prevalent in sedentary workers and musicians and is associated with neck pain, shoulder pain, and reduced pulmonary function. This two-arm parallel randomized controlled trial will compare two home-based corrective exercise programs over 12 weeks in adults with confirmed UCS. Both groups (Experimental, EG; Control, CG) perform the same 20-minute program three times per week: diaphragmatic breathing re-education and targeted muscle strengthening and stretching. The EG additionally uses a volumetric incentive spirometer (Coach2, 4000 mL) as respiratory biofeedback and receives active remote reinforcement (biweekly video calls + asynchronous educational material from a physiotherapist); the CG performs the same exercises without the spirometer and receives only minimal adherence monitoring. Outcomes are assessed at baseline (week 0) and at weeks 4, 8, and 12. Primary outcome: craniovertebral angle (CVA) measured by lateral photogrammetry. Secondary outcomes: rounded shoulder angle (RSP), thoracic kyphosis (bubble inclinometer and smartphone inclinometer), pain (Visual Analogue Scale), cervical disability (Neck Disability Index), shoulder pain and disability (SPADI), exercise adherence, and pulmonary function (spirometry: FVC, FEV₁/FVC, MVV) at weeks 0 and 12. Recruitment will take place at the Associació Amics de la Música de Meliana, Fisioterapia A Punto, and Universidad Cardenal Herrera CEU (Valencia, Spain). A total of 96 participants (48 per arm) will be enrolled over a 2-year recruitment window.

실험적: Experimental Group (EC)
Home-based corrective exercise program (3 sessions/week × 12 weeks, 20 min/session) combining: (1) diaphragmatic breathing re-education with a volumetric incentive spirometer (Coach2, 4000 mL, Smiths Medical) as biofeedback - 4 progressive levels, 10 repetitions; (2) muscle strengthening and stretching targeting the deep cervical flexors, lower and middle trapezius, rhomboids, and pectoral/suboccipital muscles. The EG additionally receives active remote reinforcement: a biweekly video call with a physiotherapist and asynchronous educational material (written guides and video tutorials) delivered via a messaging platform. |

활성 비교기: Control Group (CG)
Identical home-based corrective exercise program (3 sessions/week × 12 weeks, 20 min/session) with the same muscle strengthening and stretching exercises. The CG does not use an incentive spirometer (diaphragmatic breathing performed without device) and does not receive active remote reinforcement; adherence monitoring is minimal (standardized paper diary). |

Craniovertebral Angle (CVA)
기간: Baseline (Week 0), Week 4, Week 8, Week 12
|
Angle formed between the horizontal line at the C7 spinous process and the line connecting C7 to the ipsilateral ear tragus, measured by lateral photogrammetry using standardized adhesive markers and Kinovea software. A lower CVA indicates greater forward head posture (normal > 52°). |
