Illustration of the novel evaluation tools.
(A) manual tactile test (B) pinch-holding-up activity test.

Demonstration of the pinch and load force VS time graph.
The solid line represents the pinch force and the dashed line represents the load force.

Overall comparison different hand function tests between the patients and the healthy.
***p < .001. Bars are plotted with mean and standard deviation. Each subgraph represents the following: Purdue Pegboard test: (A) dominant hand, (B) non-dominant hand, (C) both hands and (D) assembly; SWM test: (E) thumb and (F) little finger; (G) Grip force; MTT: (H) roughness, (I) shape and (J) weight subtest; PHUA parameters: (K) Static FPPeak, (L) FPPeak, (M) FR, (N) % Static FPPeak and (O) FRNorm.
