Keywords: Neuromuscular electrical stimulation, physical fitness, cystic fibrosis INTRODUCTION Cystic Fibrosis (CF) is the most common life-limiting genetic disease in caucasians. 1 Skeletal muscle weakness and exercise intolerance is prevalent in people with cystic fibrosis. 2 Although higher levels of fitness have been associated with better quality of well-being and improved eight year survival training among individuals with CF is limited due to fatigue, hypoxaemia and dyspnoea. 3 Neuromuscular electrical stimulation (NMES) has demonstrated improvements in muscle strength, exercise tolerance and aerobic capacity in cardiorespiratory disease populations, while having minimal impact on oxygen saturation levels and heart rate. 4,5 METHODS 11 participants (9 males, 2 females) undertook a 6 week NMES training program. Training consisted of NMES to the major leg muscles (Figure 1) for 1 hour /day, 5 days a week for 6 weeks. The effects of the intervention were measured by means of pulmonary function testing (PFT), a Modified Shuttle Walk Test (MST) and isokinetic measurement of quadriceps (Q) and hamstring (H) strength. Descriptive statistics were used to analyse the results. RESULTS 6 participants (5 males and 1 female) completed the study (Age: ± 5.12 years, BMI: ± 2.49 kg/m 2 ). 5 participants withdrew (4 due to pulmonary exacerbations and 1 due to personal reasons). Results are presented in Table 1. CONCLUSION NMES does appear to have potential as a means of physical training for people with CF for whom participation in traditional exercise programs is not feasible. REFERENCES 1.
