Objective
The aim of this study was to find out the factors related to the recovery of hand motor function in patients with subcortical hemorrhage. Method: We investigated 21 patients with subcortical hemorrhage prospectively. We used their CT and/or MR imaging for the localization and estimation of the size of lesion. The Hand Movement Scale (HMS) was used for evaluation of the hand function. Proprioception, initial shoulder and hand recovery were also measured every month for at least 6 months during the follow up periods. Results: There are 13 patients with putaminal hemorrhage and 8 patients with thalamic hemorrhage. There is no difference in general characteristics between the two groups. When recovery began within 4 weeks after onset, only thalamic hemorrhage patients showed significantly good recovery. Initial shoulder shrug, especially within 4 weeks after onset, could be one of the prognostic factors of good hand motor recovery. Putaminal hemorrhage patients, who had higher scores on the hand movement scale, showed early recovery of proprioceptive function. Conclusion: Among many other factors which can be involved in the recovery of hand function in patients with subcortical hemorrhage, the time of initial hand motor recovery, the time of initial shoulder shrug, and proprioceptive function were most important.
