Comparison Of Incremental And Endurance Shuttle Walk Testing After Pulmonary Rehabilitation

Comparison of laboratory- and field-based exercise tests for COPD: a systematic review

“… 63 , 65 , 66 One study assessing responses to pulmonary rehabilitation reported similar sensitivities for the 6MWT and the ISWT, with both giving responses that exceeded the MCID. 61 All four studies assessing the sensitivity of the ISWT and the ESWT to pulmonary rehabilitation reported a significant improvement in performance for both tests; 23 , 47 , 60 , 62 however, in all four studies the response of the ESWT was greater and in two the ISWT response did not reach the MCID. 23 , 47 An additional study suggested that although both tests showed a significant response that was above the MCID, the ESWT was more responsive to pulmonary rehabilitation than the 6MWT.…”

“…Nine of the eleven studies assessing the 6MWT after pulmonary rehabilitation, 53 – 55 , 57 , 59 , 61 , 63 , 65 , 66 two of the four studies assessing 6MWT after bronchodilators, 18 , 67 and the only study assessing the 6MWT after lung-volume reduction surgery 71 all reported distance improvements greater than the MCID. Additionally, three of the five studies assessing ISWT 60 – 62 and all five of the studies assessing ESWT after pulmonary rehabilitation 23 , 47 , 59 , 60 , 62 reported distance improvements greater than the MCID. Performance improvements were also observed to be in excess of the MCID in the only two studies assessing the ESWT following bronchodilator therapy; 14 , 69 this was therefore the only exercise test reported by multiple papers that consistently responded to therapeutic interventions to a clinically relevant degree.…”

“… 12 Of the eleven studies assessing the 6MWT in response to pulmonary rehabilitation, nine reported an increase in excess of the recognized MCID, 53 – 55 , 57 , 59 , 61 , 63 , 65 , 66 with another reporting a significant increase in distance of less than the MCID 64 (the remaining study reported no significant change in 6MWT distance after pulmonary rehabilitation 58 ); these increases ranged in magnitude from 4.8% to 36.3%. Five studies reported a significant response of the ISWT to pulmonary rehabilitation ranging from 15.0% to 52.9%, 23 , 47 , 60 – 62 with three finding that the distance observed reached the MCID. 60 – 62 All five studies assessing the sensitivity of the ESWT to pulmonary rehabilitation reported that distance and/or duration increased in excess of the MCID (increases ranged from 88.0% to 205.4% when expressed as time [seconds]; 23 , 47 , 59 , 60 , 62 and from 92.0% to 140.0% when expressed as distance [meters]).…”

Reliability and Responsiveness of Endurance Shuttle Walk Test to Estimate Functional Exercise Capacity in Patients with Chronic Obstructive Pulmonary Disease: A Systematic Review and Meta-analysis

“…The responsiveness of ESWT following PR 1 , 2 , 24 , 38 - 40 showed a low to large ES (0.18–2.9) following BD, 23 , 26 SRM was 0.56 to 0.93, and larger ES (1.08 and 0.69) was reported following AO. 27 , 37 The studies 1 , 22 , 47 , 48 assessing the response of ESWT and ISWT following PR resulted in a significant improvement following both tests. 1 , 22 , 47 , 48 The response to ESWT was greater in all four studies whereas in two the response to ISWT did not reach its MCID.…”
