Plantar Pressure Changes and Their Relationships with Low Back Pain during Pregnancy Using Instrumented Insoles

Figure 2

Typical pressure data from the four sensors showing the gait parameters considered in this study during an actual test. PHL is the peak pressure at the heel sensor, PM1 and PM5 are the peak pressures at the first and fifth metatarsal heads, and PFT is the peak pressure at the first toe. Stance phase time was calculated by measuring the time from when the heel strikes until the toe-off.
