Predictors: (Constant), Pinch strength of affected hand, Touch threshold of little finger of the unaffected hand, Ratio of the median ulnar Vibration threshold of little finger in the unaffected hand, Age, PainTolerance of the Unaffected hand, Grip strength of affected hand. Only those were significant bolded (p<0.05); but all those that approach significance (p<0.10; highlighted) were brought forward into function modeling with the criteria that there have to be at least one variable representing each construct-hence one pain item also brought forward.
