Study design: A cross-sectional study. Objectives: To investigate reliability, discriminative ability and concurrent validity of three functional tests (including the 10-meter walk test (10MWT), timed up and go test (TUGT) and five times sit-to-stand test (FTSST)) using the Functional Independence Measure Locomotor (FIM-L) scores as a standard criterion. Setting: A tertiary rehabilitation center, Thailand. Methods: Subjects were 66 patients with spinal cord injury (SCI), who were able to walk at least 50 m unassisted with or without a walking device (FIM-L scores 6-7). They were tested for functional ability using the 10MWT, TUGT and FTSST. Sixteen subjects also assessed the ability using three assessors to evaluate the inter-tester reliability of the tools. Results:The three functional tests demonstrated excellent inter-tester reliability (intraclass correlation coefficient (3,3) ¼ 0.997-1.00) and could clearly distinguish between subjects who walked with and without a walking device. In addition, the tests showed significant correlation with walking categories or FIM-L scores (r pb ¼ 0.778, À0.692 and À0.595 for the 10MWT, TUGT and FTSST, respectively, Po0.001). Conclusion:The findings support reliability and validity of the 10MWT, TUGT and FTSST to assess levels of independences in ambulatory subjects with SCI.

The findings supported the discriminative validity of the tools, allowing them to indicate functional changes in persons with SCI who walk with different AADs. However, the non-significant differences between subjects who used a walker and crutches may relate to the method of subject arrangement and inclusion criteria that recruit subjects with rather good walking capability and lower limb function. The findings may also suggest the use of the sit-to-stand maneuver as a simple screening tool for walking advancement of walker users, pending further investigation.

Background/Objectives: More than half of independent ambulatory patients with spinal cord injury (SCI) need a walking device to promote levels of independence. However, long-lasting use of a walking device may introduce negative impacts for the patients. Using a standard objective test relating to the requirement of a walking device may offer a quantitative criterion to effectively monitor levels of independence of the patients. Therefore, this study investigated (1) ability of the three functional tests, including the five times sit-to-stand test (FTSST), timed up and go test (TUGT), and 10-meter walk test (10MWT) to determine the ability of walking without a walking device, and (2) the inter-tester reliability of the tests to assess functional ability in patients with SCI. Methods: Sixty independent ambulatory patients with SCI, who walked with and without a walking device (30 subjects/group), were assessed cross-sectionally for their functional ability using the three tests. The first 20 subjects also participated in the inter-tester reliability test. Results: The time required to complete the FTSST <14 seconds, the TUGT < 18 seconds, and the 10MWT < 6 seconds had good-to-excellent capability to determine the ability of walking without a walking device of subjects with SCI. These tests also showed excellent inter-tester reliability. Conclusions: Methods of clinical evaluation for walking are likely performed using qualitative observation, which makes the results difficult to compare among testers and test intervals. Findings of this study offer a quantitative target criterion or a clear level of ability that patients with SCI could possibly walk without a walking device, which would benefit monitoring process for the patients.

This study was to develop and validate the circular tandem walk test (CTWT) by deriving an optimal cutoff score to indicate the fall risk in 89 active community-dwelling older individuals. The participants aged 65 years and older were assessed for their demographic data, fear of fall variables, and history of falls in the past 6 months. Subsequently, participants were randomized for the sequence of tests between the tandem walk test and the CTWT. The outcomes of CTWT showed the highest significant correlation with all the fall variables (ranging from .631 to .827, p < .001). Moreover, the time to perform the CTWT ≥ 14.6 s and ≥ two error scores had excellent and acceptable diagnostic accuracy to determine the risk of falls in the older individuals, respectively. The CTWT can be used as alternative screening tests for assessing the fall risk in active older adults in community settings.
