Abstract: Silva A. C. et al.: Effect of aerobic training an ventilatory muscle endurance of spinal cord injured men. Spinal Cord 36 (1998)240-245 Spinal cord injury (SCI) patients typically demonstrate a loss of ventilatory muscle function. Few studies however have examined their dynamic ventilatory function. This study sought to compare the ventilatory muscle endurance (VME) of complete SCI patients with that of able-bodied controls and to evaluate the effect of an upper extremity arm cranking aerobic training device for these individuals. Twelve patients with SCI (ASIA Class A) between T1 and T12 were compared with 12 able-bodied controls. Subjects were matched for age body mass and training status. Baseline testing of all subjects included routine spirometry maximal voluntary ventilation in 12 seconds (MVV-12) and VME. VME was measured as the length of time a subject could maintain a target ventilation corresponding to 70 % of the MVV. Subjects then underwent a six week training session of supervised arm cranking ergometry at 30 minutes per session three times per week. Baseline tests were then repeated. Overall the SCUI group demonstrated improvement in all studied variables as compared with controls. Following arm-crank training the post-training VME time was found to be not significantly different than the initial times of able-bodied controls. Conclusion: This study of 12 SCI patients suggests that arm-crank aerobic training can improve and bring to near normal the dynamic ventilatory function or paraplegic patients. schö
