Functional Ambulation Profile

Background The Spinal Cord Injury Functional Ambulation Profile (SCI-FAP) is a valid, reliable measure of walking skill (eg, walking while negotiating obstacles, doors, and stairs). Objective The responsiveness of the SCI-FAP was assessed at least 7 months after spinal cord injury (SCI) and compared with that of the 10-Meter Walk Test (10MWT) and the Six-Minute Walk Test (6MWT). Design A secondary analysis of data collected during a randomized, single-blind, crossover trial was performed. Methods Participants had incomplete SCI and could walk at least 5 m without manual assistance. After 3 or 4 baseline assessments, participants completed 2 months of precision training (stepping over obstacles and onto targets on the ground) and 2 months of endurance training (treadmill training with body weight support, if needed). Walking function was assessed with the SCI-FAP, 10MWT, and 6MWT. Internal responsiveness was evaluated through change scores and standardized response means (SRMs). External responsiveness was gauged by correlating change scores on the SCI-FAP, 10MWT, and 6MWT. The minimal detectable change was calculated from the standard error of measurement from the baseline assessments. Results The SCI-FAP scores improved with both interventions. The magnitude of change was greater for participants whose pretraining self-selected speed was less than 0.5 m/s. The SCI-FAP had moderate SRMs. The 10MWT (fastest speed) and 6MWT had the largest SRMs after precision training and endurance training, respectively. The minimal detectable change in the SCI-FAP was 96 points. Limitations The convenience sample was small and all participants could ambulate independently (with devices); therefore, the generalizability of the findings is limited. Conclusions The SCI-FAP was responsive to changes in walking ability in participants who had incomplete SCI and walked at slow speeds, but overall the 10MWT and 6MWT were more responsive.

Objectives. This study aimed to establish the minimal detectable change (MDC) and clinically important differences (CID) of the Wolf Motor Function Test (WMFT) in patients with stroke, and to assess the proportions of patients' change scores exceeding the MDC and CID after stroke rehabilitation. Methods. A total of 57 patients received 1 of the 3 treatments for 3 weeks and underwent clinical assessments before and after treatment. The MDC, at 90% confidence (MDC 90), was calculated from the standard error of measurement to indicate a real change for individual patients. Anchor-based and distribution-based approaches were used to triangulate the values of minimal CID. The percentages of patients exceeding the MDC and minimal CID were also examined. Results. The MDC90 of the WMFT was 4.36 for the performance time (WMFT time) and 0.37 for the functional ability scale (WMFT FAS). The minimal CID ranged from 1.5 to 2 seconds on the WMFT time and from 0.2 to 0.4 points on the WMFT FAS. The MDC and CID proportions ranged from 14% to 30% on the WMFT time and from 39% to 65% on the WMFT FAS, respectively. Conclusions. The change score of an individual patient has to reach 4.36 and 0.37 on the WMFT time and WMFT FAS to indicate a real change. The mean change scores of a stroke group on the WMFT time and WMFT FAS should achieve 1.5 to 2 seconds and 0.2 to 0.4 points to be regarded as clinically important changes. Furthermore, the WMFT FAS may be more responsive than the WMFT time based on the results of proportions exceeding the threshold criteria.

A Prospective Study

Objective: To determine the minimal clinically important difference of the Mini-BESTest in individuals’ post-stroke. Design: Prospective cohort study. Setting: Outpatient stroke rehabilitation. Subjects: Fifty outpatients with stroke with a mean (SD) age of 60.8 (9.4). Intervention: Outpatients with stroke were assessed with the Mini-BESTest before and after a course of conventional rehabilitation. Rehabilitation sessions occurred one to two times/week for one hour and treatment duration was 1.3–42 weeks (mean (SD) = 17.4(10.6)). Main measures: We used a combination of anchor- and distribution-based approaches including a global rating of change in balance scale completed by physiotherapists and patients, the minimal detectable change with 95% confidence, and the optimal cut-point from receiver operating characteristic curves. Results: The average (SD) Mini-BESTest score at admission was 18.2 (6.5) and 22.4 (5.2) at discharge (effect size: 0.7) ( P = 0.001). Mean change scores on the Mini-BESTest for patient and physiotherapist ratings of small change were 4.2 and 4.3 points, and 4.7 and 5.3 points for substantial change, respectively. The minimal detectable change with 95% confidence for the Mini-BESTest was 3.2 points. The minimally clinical importance difference was determined to be 4 points for detecting small changes and 5 points for detecting substantial changes. Conclusions: A change of 4–5 points on the Mini-BEST is required to be perceptible to clinicians and patients, and beyond measurement error. These values can be used to interpret changes in balance in stroke rehabilitation research and practice.
