The outcomes of the DASH, VAS, SWMT, MPUT, and MIGF tests were tabulated in Excel (Microsoft Office Excel, version 2007, Microsoft; Redmond, Washington) and stored for statistical analysis.
However, we can only speculate about the possible effect of diminished proprioception because no assessments of proprioceptive deficit other than SWMT were performed in the current study.
Abbreviations: ADL = activity of daily living; AUSCAN = Australian/Canadian Osteoarthritis Hand Index; DASH = Disabilities of the Arm, Shoulder and Hand (questionnaire); GFP = grip force peak; FMLO = grip force at moment of liftoff; MIGF = maximum isometric grip force; MPUT = Moberg Pickup Test; MPUTEC = MPUT with eyes closed; MPUT-EO = MPUT with eyes open; OA = osteoarthritis; PE = percentage error rate; PVEL = peak velocity of instrumented object; SWMT = Semmes-Weinstein Monofilament Test; VAS = visual analog scale.
The result in SWMT is obtained as number of correct responses and number of non-adjacent errors at 0 sec and at 20 sec delay respectively.
On SWMT at immediate delay there was no difference in committing non adjacent errors among the three groups.
In SWMT and CPT, the bipolar group performed significantly better than the schizophrenic group and infact, this group was comparable to the control group.
