Table 4:

CMTPedS Total scores for patients requiring assistive devices or orthopedic surgery during the 2-year follow-up.

Intervention	N (%)	Baseline Score	Follow-up Score	Difference	Change (% from baseline)
Assistive devices	12 (6)	16.6±11.9 (1 – 35)	19.0±12.9 (1 – 38)	2.4±5.7* (95%CI, 0.3 – 6.0)	12
Orthopedic surgery	14 (8)	20.4±9.3 (7 – 39)	23.3±7.6 (14 – 37)	2.9±4.3* (95%CI, 0.1 – 6.0)	14
No intervention	161 (86)	17.0±8.8 (1 – 40)	19.3±9.2 (0 – 42)	2.3±4.9* (95%CI, 0.5 – 3.0)	14

Data are mean±SD (range) for baseline and follow-up scores and mean±SD (95% Confidence Interval) for Difference scores.

^*Significant change from baseline (p<0.001). There was no significant difference between children requiring assistive devices or orthopedic surgery, and children who had no intervention in the baseline CMTPedS Total scores or rate of progression (p>0.05).
