Static footprint analysis, rat sciatic nerve injury

Toe Spread(TS) = 1-5 toe spread

ITS(intermediate toe spread)  = 2-4 toe spread

PL  (Print Length)

Toe Spread Factor (TSF) = (Operated TS - Non-Operated TS)/Non-Operated TS

Intermediate toe spread factor (ITSF) = (Operatied ITS - Non-Operated ITS)/Non-Operated ITS

Print Length Factor (PLF) = (OPL-NPN)/NPL

Sciatic Function Index(SFI) = (-38.3xPLF) + (109.5xTSF) + (13.3 ITSF) -8.8

Static Sciatic Index (SSI) = (108.44 x TSF) + (31.85xITSF) -5.49
