Table 2.
Toe height characteristics at the Minimum Toe Clearance (MTC) swing-phase event.
| Older group | Stroke participant | |||||||
|---|---|---|---|---|---|---|---|---|
| Baseline | Retention | Baseline | Retention | |||||
| Left foot | Right foot | Left foot | Right foot | Left foot | Right foot | Left foot | Right foot | |
| Toe height (mm) | 15.3 | 14.4 | 19.5* | 35.5* | 29.1 | 16.6 | 34.9 | 24.9 |
| Toe height SD (mm) | 3.6 | 5.4 | 4.0 | 8.3 | 5.4 | 13.0 | 5.3 | 8.8 |
| Skewness | 1.20 | −0.36 | 1.04 | 0.73 | 0.44 | 2.88 | 0.60 | 2.08 |
| Kurtosis | 1.66 | 1.38 | 1.58 | 1.60 | 0.29 | 11.27 | −0.13 | 8.35 |
| Contact frequency | 2482 | 641 | 269 | >105 | >105 | 3 | >105 | 161 |
SD is toe height standard deviation. Contact Frequency is the predicted frequency of toe contact with a 1 cm high obstruction at MTC, i.e., 641 represents predicted contact once in every 641 strides. Higher frequency represents lower tripping probability.
