| Parameters | Mean velocity (m/s) r (95% CI) p | Max knee flex vel in GC (°/s) r (95% CI) p | Max hip flex vel. in (°/s) r (95% CI) p | |||
|---|---|---|---|---|---|---|
| P1-PKF (°) | 0.56* | 0.03 | 0.87** | 0.00 | 0.72* | 0.00 |
| P2-Range in early swing (°) | 0.25 | 0.24 | 0.59* | 0.02 | 0.40 | 0.14 |
| P3-Total range (°) | 0.57* | 0.02 | 0.90** | 0.00 | 0.73** | 0.00 |
| P4-Duration in early swing (% GC) | 0.18 | 0.52 | 0.23 | 0.42 | 0.24 | 0.38 |
CI: confidence interval; ext: extension; flex: flexion; GC: gait cycle; m: meters; max: maximum; PF: plantar flexion; PKF: peak knee flexion; s: seconds; vel: velocity. Significant p values are bolded.
*Significant result (p < 0.05), **Highly significant result (p < 0.01).
