Method ological factors affecting 6MWD include track length , encouragement , supplemental oxygen and walking aids .
Supplemental oxygen also affects ISWT and ESWT performance .
Responsiveness was moderate to high for all tests , with greater responsiveness to interventions that included exercise training .
The findings of this review demonstrate that the 6MWT , ISWT and ESWT are robust tests of functional exercise capacity in adults with chronic respiratory disease
This systematic review examined the measurement properties of the 6-min walk test ( 6MWT ) , incremental shuttle walk test ( ISWT ) and endurance shuttle walk test ( ESWT ) in adults with chronic respiratory disease .
Energy Expenditure at Rest and during Walking in Patients with Chronic Respiratory Failure: A Prospective Two-Phase Case-Control Study
Background Measurements of Energy Expenditure ( EE ) at rest ( REE ) and during physical activities are increasing in interest in chronic patients . In this study we aim ed at evaluating the validity/reliability of the SenseWear ® Armb and ( SWA ) device in terms of REE and EE during assisted walking in Chronic Respiratory Failure ( CRF ) patients receiving long-term oxygen therapy ( LTOT ) . Methodology /Principal Findings In a two-phase prospect i ve protocol we studied 40 severe patients and 35 age-matched healthy controls . In phase-1 we determined the validity and repeatability of  REE  measured by SWA ( REEa ) in comparison with st and ard calorimetry ( REEc ) . In phase-2 we then assessed EE and Metabolic Equivalents-METs by SWA during the 6-minute walking test while breathing oxygen in both assisted ( Aid ) or unassisted ( No-Aid ) modalities . When compared with REEc , REEa was slightly lower in patients ( 1351±169 vs 1413±194 kcal/day respectively , p<0.05 ) , and less repeatable than in healthy controls ( 0.14 and 0.43 coefficient respectively ) . COPD patients with CRF patients reported a significant gain with Aid as compared with No-Aid modality in terms of meters walked , perceived symptoms and EE . Conclusions / Significance SWA provides a feasible and valid method to assess the energy expenditure in CRF patients on LTOT , and it shows that aided walking results in a substantial energy saving in this population
