Abstract
Assessing function is an important outcome measure in establishing evidence based practice. Currently, there are no well-accepted functional measures that encompass both physical activity and environment interaction. The purpose of this study was to develop and validate a quantifiable functional measure that incorporates physical activity and environmental factors. Sixteen volunteer participants (age [mean± SD] = 28.9 ± 12.0 years; height= 171.9 ± 8.4 cm; weight= 80.9 ± 16.6 kg} were assigned to two groups; post-surgical knee (n = 8; < 7 days after surgery= 4.1 ± 2.8 days} and control (n = 8). Two physical activity measures, step count (volume} and activity count (intensity}, were obtained using minute-by-minute accelerometry. Participants' locations and travel were recorded using GPS. Participants, under free living conditions, wore the accelerometers and GPS receivers on their waist for three days one week after surgery and 2 months later. The step count and GPS data were combined to produce a MAPSv (volume} score and the activity count and GPS data were combined to produce a MAPSi (intensity} score. The reliability for MAPSv and MAPSi scores over three days was acceptable (ICC[l, 1] = .84 - .89). Validity evidence was demonstrated by a significant correlation with a self-report functional knee scale. MAPSv was correlated with all of the Knee Injury and Osteoarthritis Outcome Score (KOOS) subscales. MAPSi was correlated with all of the KOOS subscales except pain (r = .484; p = 0.058). There were significant differences between the post-surgical and control groups for both MAPSv (t,9.9 = -3.60; p = .007; post-surgical= 14.16 ± 9.71, control= 57.34 ± 32.48) and MAPSi (t10.B = -3.22; p = .013; post-surgical = 480.58 ± 344.01, control= 2143.30 ± 1419.66) immediately following surgery. The ANOVA results for MAPSv indicated that there was a significant time-group interaction, F (1, 12) = 4.60, p = .05. However, for MAPSi there was not a statistically significant time-group interaction, F (1, 12) = 3.42, p = .09. The results provide known-group difference and convergent validity evidence for the use of MAPSv as a functional outcome measure. It also shows evidence that MAPSv is sensitive to the changes in function over time.
