Purpose/Hypothesis: The Six Minute ...

Purpose/Hypothesis: The Six Minute Walk experiment (SMWT) has been used extensively Lu trial functional ability and measure progres in the somewhat advanced in life and individuals with pulmonary or cardiac disorders. The SMWT is typically performed across a 100-foot long hallway, yet in an effort to make the experiment easier to administer, some clinics perform the SMWT onward a treadmill (TM). The reliability and validity of this modification is questionable. The intention of this study was to examine the intra-test reliability of the SMWT performed overground (OG) and onward a TM and to compare the distance transversed subordinate to each situation. Number of Subjects: A convenience sample of twenty healthy men and women association students (mean age 2.3.3 ?± 28 years) serv as make subordinates Materials/Methods: Subjects performed the OG SMWT following the protocol of the American Thoracic Society twice in succession the same day. On a separate day, a TM pretest was performed to determine an appropriate starting velocity and then the TM SMWT was performed twice. issue measures included total distance achieved and heart rate (HR) as measured by way of ECG radio-telemetry. Results: Both TM and OG protocols demonstrated high intra-test reliability (TM ICC = 0981 OG ICC = 0988) A statistically significant difference was plant between the mean distances for theTM (2424 ?± 205 feet) and OG (2349 ?± 41 feet) SMWT (p=002) Average HR values for the TM (1337 ?± 468 bpm) and OG (1357 ?± 158 bpm) were not statistically different (p=026) Conclusions: The SMWT performed forward both theTM and OG demonstrated high reliability. The difference in distance between TM and C)CJ was statistically significant yet was of negligible clinical importance as the average difference was solitary 76 feet or a 3% variation. Heart rate rejoinders demonstrated a similar physiological answer between the two protocols. These conclusions substantiate the interchangeability of the TM and OG SMWT protocols when used with healthy enthralls Clinical Relevance: The results of this studious mood need to be replicated with patient subgroup to confirm reliability of the TM SMWT and the clinical interchangeabilily between the protocols.
