Fingers flexors. (Upper): Mean ± SD of muscle tone, posture and pain at T0 and T1; p-values refer to the evaluation of the change from T0, based on the linear mixed models with random intercept for muscle tone and pain and to mixed-effects logistic regression model for severe abnormal flexion in posture scores. All the models were adjusted for age and sex. Muscle tone and posture T0-T1 changes were evaluated for all the patients (n = 64), while improvement in pain was studied only among patients with pain at T0 (n = 27). (Below): Mean ± SD of muscle tone, posture and pain at T0 and T1 among patients with normal p-ROM (dashed line) and abnormal p-ROM (solid line) at T0. p-values refer to the comparison of the pattern changes between the two groups testing the Time*Group interaction in linear mixed models or in the mixed-effects logistic model.
