7^th International Chronic Obstructive Pulmonary Disease Conference

Neuromuscular electrical nerve stimulation (NMES) is a new modality being investigated for its effect related to quadriceps strength and walking distance in chronic obstructive pulmonary disease (COPD) patients. The purpose of this small pilot study was to observe and absorb as much information possible on the methodology and learning outcomes. Information from this small pilot study would present recommendations for the possibility of a larger national study regarding this new modality. For this aim, a mixed method approach was deemed appropriate. A total of seven moderate to severe COPD patients were included in this feasibility study, four in the experimental group and three in the control group. Following patient consent, the quadriceps strength as well as a 6-minute walk test (6MWT) was completed. The objective measures were taken at the baseline of this study, i.e. week four and week eight. Positive outcomes were reported in all subjects with the experimental group benefitting the most. However, the results are insignificant in view of the small population sampling. A self-designed questionnaire was distributed to the experimental group at the end of the study, with the aim to get a better view on how patients felt during the duration of NMES. Constant feedback was kept during the study duration between the researcher, intermediary physiotherapist and the subjects. Constant feedback and the results from the questionnaire were important for the researcher to present recommendations based on the strength, limitations and learning outcomes. This feasibility study provided guidance for larger more randomized national studies to maximize the benefits of NMES in COPD patients.
