Low Volume Nose Resistance Breathing Exercise With Incentive Spirometer in Patient With Cervical Spinal Cord Injuries

This randomized clinical trial aims to evaluate the effectiveness of combining Low Volume Nose Resistance Breathing Exercises (LVNRBE) with Incentive Spirometry (IS) on respiratory outcomes in patients with cervical spinal cord injury (SCI). Respiratory complications are a major concern in cervical SCI due to impaired respiratory muscle function, leading to reduced lung volumes, dyspnea, ineffective cough, and sputum retention. The study will recruit 42 inpatients aged 18-38 years with cervical SCI (C4-C7), randomly divided into two groups: Data Analysis: Statistical tests (paired and independent t-tests) will determine intra- and intergroup differences using SPSS v25, with significance set at p \< 0.05. * Group A (Intervention): Receives LVNRBE using an Acapella device plus IS for 20 minutes, three times daily, five days a week for four weeks. * Group B (Control): Receives conventional respiratory physiotherapy with the same frequency and duration. Outcomes will be assessed pre- and post-intervention using: * Pulmonary Function Tests (FVC, FEV1), * Modified Borg Dyspnea Scale, * Cough Frequency Scale, * Sputum Grading Scale.
