Traumatic Spinal Injury: Preliminary Results of Respiratory Function, Voice and Quality of Life

Abstract

Assess respiratory muscle strength, voice and the quality of life of patients with traumatic cervical and thoracic spinal cord injury. Preliminary analytical case control study of 28 adult men, aged between 18 and 65 years, divided into two groups: a research group consisting of 14 patients with cervical and thoracic spinal cord injury, and control group (CG) with 14 noninjured individuals. The subjects had their maximum inspiratory and expiratory pressures measured, underwent voice handicap index-10 assessment, had their voices recorded for auditory perception analysis, using the voice deviation and GRBASI scales, and for acoustic analysis, based on extraction of the parameters selected and completed a quality-of-life questionnaire (WHOQOL-bref protocol). Intergroup comparison indicated that the research group exhibited lower respiratory muscle strength in relation to the CG, MIP and MEP P-values < 0.001 and < 0.001, respectively; and in relation to the device's reference value, MIP and MEP P-values < 0.001 and < 0.001, respectively; the patients reported no voice handicaps according to the voice handicap index; overall vocal deviation severity on the voice deviation was higher in the CG, P = 0.040; there was greater occurrence of roughness and instability on the GRBASI scale, P= 0.040; there was greater difficulty in modulating vocal frequency (P= 0.002) and resonance, with a laryngopharyngeal focus; the acoustic parameters were normal; and lower scores were obtained in the physical domain of quality of life (P< 0.001). The individuals with traumatic spinal cord and thoracic injury exhibited changes in respiratory measures, vocal deviation and dissatisfaction in the physical domain of the WHOQOL-bref protocol.
