The effect of treatment with a non-invasive foot worn biomechanical device on subjective and objective measures in patients with knee osteoarthritis- a retrospective analysis on a UK population

Table 2 Spatial-temporal parameter changes in knee OA patients after 3 and 6 months of treatment. Results are presented as mean (SD) [95% CI]

	Baseline	3 months	6 months	P-value
Velocity (cm/s)	91.88 (20.68) [89.97–93.78]	102.69 (19.19) [100.92–104.46]	104 (19.12) [102.23–105.76]	< 0.001
Step length- more symptomatic limb (cm)	53.96 (8.8) [53.15–54.78]	57.70 (8.36) [56.93–58.48]	58.15 (8.36) [57.384–58.93]	0.001
Step length- less symptomatic limb (cm)	54.07 (9.0) [53.24–54.9]	57.86 (8.63) [57.06–58.66]	58.34 (8.44) [57.564–59.12]	< 0.001
Single limb support- more symptomatic limb (% GC^*)	36.55 (2.42) [36.32–36.79]	37.68 (2.10) [37.49–37.88]	37.72 (2.09) [37.53–37.92]	< 0.001
Single limb support- less symptomatic limb (% GC^*)	38.34 (2.06) [38.15–38.53]	38.53 (1.99) [38.34–38.71]	38.56 (1.93) [38.39–38.74]	0.003

N = 455; *GC Gait Cycle; P-value was set to P < 0.05
Repeated measure ANOVA’s were performed for the differences between the outcomes, measured at baseline, 3 and 6 months into treatment. Significant differences were found between baseline and 3 months and baseline and 6 months
