The aim of the study was to identify whether the additional information measured by the My Wellness Key^TM（MWK） accelerometer during a treadmill 6-min walk test（t-6MWT） was related to currently used outcome measures.Methods： Fifteen participants（9 males, 6 females） performed a self-paced t-6MWT. Respiratory gas analysis and walking distance were measured whilst wearing the MWK.Results： A significant correlation was established between activity counts and 6-min walk distance（6MWD）（r=-0.847, p 〈 0.001） yet not 6-min walk work（6MWW）（r=-0.337, p=0.220）. Energy expenditure estimated by the MWK was strongly correlated to 6MWW（r=0.938, p 〈 0.001）but not 6MWD（r=0.477, p=0.072）. The MWK significantly underestimated energy expenditure（36.73, CI=33.9-39.7 kcal） compared to gas analysis（54.35, CI=46.2-61.4 kcal） demonstrating poor agreement between the two analyses（Bias=-17.61 kcal, Limits of agreement=-37.4,t2.2 kcal）. Measurement of time spent undertaking light, moderate, and vigorous physical activity was not significantly different（ p 〉 0.05）between the MWK and gas analysis.Conclusion： Estimated energy expenditure provided by the MWK was strongly correlated to 6MWW; however, MWK underestimated energy expenditure as measured by gas analysis. The MWK may provide outcome data that supplement those currently provided by the 6MWD for functional capacity assessment during the t-6MWT.展开更多

These patients need palliative care and rehabilitation is one of the methods that can be used to improve quality of life (QoL) among these patients. Yet the research conducted to assess benefits of pulmonary rehabilitation (PR) in terms of improving physical activity and QoL in IPF patients remains limited. Hence this study aims to evaluate the effect of a bespoke pulmonary rehabilitation programme, on the physical, physiological and psychological parameters and improvements of QoL among IPF patients. Eleven (11) subjects with IPF received 6 weeks of pulmonary rehabilitation. An interviewer administered quality of life questionnaire, six-minute walking test (6MWT), Incremental bicycle exercise tests were performed, and cardiac and respiratory parameters were assessed pre- and post-rehabilitation. The 6MWT was significantly increased following training (Pre 312.55<span "=""> </span>±<span "=""> </span>89.99;Post, 380.73 ±<span "=""> </span>59.60). A significant improvement was observed in overall QoL (2.226 ± 0.026), dyspnoea (<span style="color:#4F4F4F;">-</span>0.455<span "=""> </span>±<span "=""> </span>0.004) anxiety (<span "=""><span style="color:#4F4F4F;">-</span>2.070</span><span "=""> </span>±<span "=""> </span>0.038), depression (<span "=""><span style="color:#4F4F4F;">-</span>2.217</span><span "=""> </span>±<span "=""> </span><span "="">0.027) scores.

Bespoke pulmonary rehabilitation program is beneficial in short term improvement of the functional exercise capacity, dyspnoea and QoL among IPF patients.展开更多
