Table 4: Responsiveness for the PSSD, and vibrometer based on CID of ΔSSS = 0.5.

Groups N Mean Baseline Score
(SD)		 Mean Post Treatment Score
(SD)		 Mean Change
(SD)		 SRM
(CI)		 ES
(CI)
PSSD Responder 15 4.13 (1.99) 3.83 (3.53) 0.30 (3.26) 0.09 (-0.42-0.60) 0.08 (-0.43-0.59)
PSSD Non Responder 23 7.82 (9.47) 7.30 (15.29) 0.53 (13.48) 0.04 (-0.37-0.45) 0.06 (-0.35-0.47)
Vibrometer Responder 22 25.55 (19.51) 16.64 (14.46) 8.91 (14.70) 0.61 (0.20-1.02) 0.46 (0.05-0.47)

SD = standard deviation. SRM = standardized response mean. ES = effect size. PSSD = pressure specified sensory device. DASH = disability of the arm, shoulder, and hand.
CI = confidence interval. The overall effect size of all patients was calculated to indicate the overall response to orthotic intervention; SRM and ES were calculated separately for responders and non-responders to indicate responsiveness.
