During the follow-up period, statistical parametric mapping analysis demonstrated a decrease in GABAA receptor availability throughout the cerebral cortex and cerebellum, especially the contralateral hemisphere. GABAA availability in the bilateral primary motor cortex, contralateral supplemental motor cortex, and globus pallidus at T0 was positively correlated with the FMS score at T1 CONCLUSIONS: This is the first prospective, controlled longitudinal study showing that the change in GABA receptor availability over time is significantly related to motor recovery after stroke in humans. This work supports the rationale for a novel strategy to promote motor recovery after stroke.

This technique for M2L-UI3L shows high sensitivity and specificity compared with the previous reports on the diagnosis of carpal tunnel syndrome. Furthermore, the values of median-second lumbrical motor latency alone have higher sensitivity and specificity, comparable with the median sensory conduction study across the wrist segment.
