Anthropometric and kinematic measurements
| Parkinson’s disease patients | Healthy control subjects | |
|---|---|---|
| Body height, cm | 176.04 ± 7.90 | 174.24 ± 6.47 |
| Inter ASIS distance, cm | 25.53 ± 3.32 | 29.01 ± 3.47 |
| Foot length, cm | 25.41 ± 1.18 | 25.41 ± 1.52 |
| Limb length, cm | 91.83 ± 3.67 | 90.04 ± 2.96 |
| Weight, kg | 85.80 ± 13.44 | 76.54 ± 10.74 |
| BMI, kg/m2 | 27.74 ± 4.25 | 25.22 ± 3.58 |
| Stride duration, s | 1.16 ± 0.05 | 1.13 ± 0.09 |
| Stance duration, %stride | 64.60 ± 4.71 | 62.31 ± 1.62 |
| Double support duration, %stride | 28.94 ± 9.54 | 24.58 ± 3.32 |
| Stride length, %BHa | 56.81 ± 19.92 | 72.00 ± 6.41 |
| Stride average velocity, %BH/s | 49.36 ± 18.10 | 64.17 ± 9.37 |
| Stride max velocity, %BH/sa | 157.91 ± 44.63 | 199.63 ± 21.44 |
Stance and double-support duration are expressed as the percentage of the duration of the stride (i.e. the interval between two subsequent heel strikes of the same foot). The stride length and the stride velocity were calculated as a percentage of the body height of each subject (%BH). Data are shown as mean ± SD.
aStatistical significance (P < 0.05).
ASIS = anterior-superior iliac spines; BH = body height; BMI = body mass index.
