Table 1 Orthotic conditions and design features
Orthotic Condition | Design Features | Photo (Right Foot) | Theoretical orthotic effect | Laboratory variables | RunScribe variables |
|---|---|---|---|---|---|
A | - Medial arch support - Cushioned foam - Full length orthotic |
| Orthotic A reduces GRF loading rate compared to control condition. Orthotic A reduces pronation velocity and excursion compared to control condition | GRF loading Rate (N/s) | GRF loading rate (N/Kg/s) |
B | - High medial arch support - Lateral cut out to forefoot - Deep heel cup - ¾ length orthotic |
| Reduces foot pronation excursion and maximum pronation velocity compared to the control condition and Orthotic A | Pronation Excursion (°) and maximum pronation velocity (°/sec) between initial foot contact to maximum foot pronation | Pronation Excursion (°) and maximum pronation velocity (°/sec) between initial foot contact to maximum foot pronation |
C | - Gel Material - Heel only orthotic |
| Orthotic C reduces impact shock compared to the control condition | Peak positive vertical acceleration (Impact Shock (g)) | Impact Shock (g) |
