Relationship between PSFS, DASH and Level of Nerve Injury. The PSFS scores were measured on a 10 cm visual analog scale and these values were converted to millimeters to present the data comparison with the DASH scores (0–100). There was a statistically significant main effect difference with both the DASH and PSFS (p < 0.001). Post hoc analyses revealed that brachial plexus injuries had significantly higher DASH scores and lower PSFS scores compared to digital and median/ulnar/radial injuries
