Intrarater and Interrater Reliability and Concurrent Validity of the 3-Meter Backward Walk Test in Non-Frail, Pre-Frail, and Frail Older Adults in Residential Care Homes.
Importance: Assessing backward walking ability in older adults is crucial due to its strong association with balance, mobility, and fall risk. The 3-meter backward walk test (3MBWT) provides a quick and valid tool for this purpose.
Objective: The objective of this study was to assess the reliability and validity of the 3MBWT and to determine its effectiveness in differentiating between different levels of frailty.
Design: This study used a cross-section design.
Setting: The study was carried out in residential care homes for older adults.
Participants: Participants were able to walk with or without assistance and were excluded if they had a Mini-Mental State Examination score ≤ 17.
Interventions: Participants underwent the 3MBWT and the 10-metre walk test (10MWT). In addition, the Short Physical Performance Battery (SPPB) was administered.
Main outcome(s) and measure(s): Frailty was assessed using the SHARE-FI instrument, with participants classified as non-frail, pre-frail, or frail. Reliability of the 3MBWT was assessed using intraclass correlation coefficient (ICC [3,1]), and concurrent validity was assessed using the 10MWT and SPPB. Fall history over the past year was obtained from medical records and participant interviews.
Results: Participants (n = 217) were categorized as non-frail (27%), pre-frail (31%), or frail (42%). The average 3MBWT times were 5.0, 5.9, and 11.8 seconds for participants who were non-frail, pre-frail, and frail, respectively. The 3MBWT showed good to excellent intrarater reliability (ICC = 0.89-0.93) and excellent interrater reliability (ICC = 0.90-0.99). It showed strong correlations with the 10MWT (r = 0.91) and SPPB walking speed (r = 0.94), and a negative correlation with the SPPB total score (r = -0.86). Moderate correlations were found with the Falls Efficacy Scale International (r = 0.71) and Multidimensional Fatigue Inventory (r = 0.61), and a high correlation with falls in the last 12 months (r = 0.74).
Conclusions: The 3MBWT is a reliable tool for assessing physical performance and differentiating levels of frailty in older adults, with a strong association with fall history.
Relevance: The 3MBWT offers clinicians a quick, simple, and valid tool for assessing older adults in residential care.
