Evidence of motor system reorganization in complex regional pain syndrome type 1: A case report

Figures & data

Figure 1. Evolution of the delta score of the affected limb. The delta score was used to depict the strength of the corticospinal projections, with a higher delta score representing a higher strength of corticospinal projections (delta score = mean MEP amplitude at 130% – mean MEP amplitude at 110%). T0 corresponds to the score obtained at the initial visit (prior to GMI treatment), T1 to the score obtained after 2 weeks (stage 1 GMI), T2 to the score obtained after 4 weeks (stage 2 GMI) and T4 to the score obtained after 8 weeks (stage 4 GMI).

Table 1. Clinical outcomes.

	Before GMI	After GMI	Difference(before − after)	MCID
SF-MPQ VAS	4.7	2.5	2.2	2/10
SF-MPQ PRI	11	3	8	5/45
DASH (%)	55.8	27.5	28.3	10.83
Grip force (kg)	0	0.4	0.4	5

GMI = graded motor imagery; MCID = minimal clinically important difference; SF-MPQ = short form of the McGill Pain Questionnaire; VAS = visual analogue scale; PRI = pain rating index; DASH = Disabilities of the Arm, Shoulder and Hand questionnaire.
