Functional Brain Correlates of Upper Limb Spasticity and Its Mitigation following Rehabilitation in Chronic Stroke Survivors

Table 3

In response to treatment: correlations between reduction in spasticity and changes in task-related brain activation with and without adjusting for changes in motor function according to FM wrist/hand scores. Shown here are correlations >0.45.

Hemisphere	ROI	Bivariate correlations; 𝑟 (P value)	Partial correlations controlling for FM W/H; 𝑟 (P value)
Contralesional	M1	−0.745 (0.002)	−0.755 (0.003)
	LPM	−0.522 (0.05)	−0.565 (0.04)
	S1	−0.571 (0.03)	−0.614 (0.026)
	AS	−0.529 (0.05)	−0.597 (0.03)

M1: primary motor area, LPM: lateral premotor region, S1: primary sensory, and AS: associative sensory.
