  1. Notes: LSMD = lumbar segmental mobility disorders; (n) = number in group; (sd) = standard deviation; Sig. = 2-tailed significance of independent samples t-test; VAS pain = visual analog scale pain score (cm); RM-18 = 18 item modified Roland-Morris disability index score (Stratford et al. 1997); LSR = lumbar segmental rigidity; LSI = lumbar segmental instability; *statistically significant at p < .01.
