Abstract:	Introduction: Spinal cord injury (SCI) is any damage to the structures contained in the spinal canal, which can lead to motor changes. The lung function of individuals with cervical SCI is compromised by changes in the biomechanics of the rib cage due to paralysis of the abdominal and intercostal muscles and, in some cases, due to total or partial loss of diaphragm function. We hypothesize that inspiratory muscle training (IMT) with a higher load may be more beneficial for improving lung function in individuals with SCI. Objective: To evaluate the effect of specificity in quadriplegic individuals with spinal cord injury. Methodology: Randomized, blind, and controlled clinical trial in individuals diagnosed with complete motor SCI, classified as chronic tetraplegia. Participants were randomized into three groups: GI (TMI 30% S-Index), GII (TMI 50% S-Index), and CG (conventional physiotherapy). Analyzes of manovacuometry, spirometry, peak cough flow, maximum sustained pressure, pulmonary resistance, dynamic measurement of maximum inspiratory pressure (S-Index), quality of life questionnaire, and intergroup and intragroup functional capacity were performed. The IMT was performed twice a day, 5 days a week, lasting 30 minutes. Conventional physiotherapy was performed in all groups, twice a day, five days a week, with 30-minute sessions. The duration of the intervention in both groups was four weeks, in a hospital environment. Results: Ten individuals participated in the study, all male, with a mean age of 31.80±9.59 years. GI presented better values for Maximum Inspiratory Pressure (MIP) when compared to GII and CG (-90.00 ± 30.00 vs -55.00 ± 13.23, p=0.11, -66.25 ± 11.09 vs -55.00 ± 17.32, p=0.11, -78.33 ± 24.66 vs -70.00 ± 17.32, p=0.18, respectively). There was no difference between respiratory variables, quality of life, and functionality. The S-Index measured weekly showed a significant difference for the GI when compared to the others. Conclusion: Individuals with quadriplegic SCI, and chronic complete motors can benefit from training with lower loads. The S-Index can be increased with 4 weeks of training in the low-load TMI group. Quality of life and functionality did not show significant changes after IMT.
