While tetraplegia is commonly associated with paralysis of all four limbs, paralysis also affects the major respiratory muscles, namely the diaphragm, abdominal and intercostal muscles. The reduction in respiratory function results in approximately 40% of tetraplegic patients requiring mechanical ventilation in the acute stage (first six weeks) of injury to support respiration. The use of mechanical ventilation increases lifelong morbidity and mortality, delays rehabilitation, results in longer hospital stays and costs the health care provider an additional $2,000 per patient per day.
Surface electrical stimulation of the abdominal muscles, termed Abdominal Functional Electrical Stimulation (FES), can contract the abdominal muscles, even when paralysed. We have shown that surface FES of the abdominal muscles, termed Abdominal FES, improves respiratory function in tetraplegia, and respiratory function is a known predictor of mechanical ventilation time. Dr McCaughey’s pilot work also shows that eight weeks of abdominal FES is a feasible method to reduce mechanical ventilation time in acute tetraplegia.
Despite these positive results, a lack of data from randomised control trials, and lack of a standard Abdominal FES protocol, has prevented this technology from being adopted as a standard clinical treatment.
This project will provide the first information on the effectiveness and cost-effectiveness of Abdominal FES to reduce mechanical ventilation duration in tetraplegia. In addition, it will provide detailed information about respiratory function and its impact on quality of life in tetraplegia.
