The effects of somatosensory training focused on the hand on hand function, postural control and ADL of stroke patients with unlateral spatial neglect and sensorimotor deficits

Abstract

[Purpose] We investigated the effect of somatosensory training, e.g. facilitation of reaching and somatosensory stimulus of upper limb (UL) on hand function and postural control. [Subjects] The subjects were 20 stroke patients in the Bobath Memorial Hospital, who has problems with unilateral neglect, and somatosensory deficits. [Methods] The patients were divided into two groups: a unilateral neglect group (NG), and a sensrimotor deficit group (SMG). Somatosensory training for the hand was carried out eighteen times, three times a week for six weeks, together with 40 minutes preservative treatment. To compare the groups, we used several assessment tools: the manual function test (MFT), the postural assessment scale for stroke (PASS) and the functional reach test (FRT). [Results] In NG, somatosensory training for the hand significantly improved MFT, and PASS (p<0.05). In the SMG, somatosensory training for the hand significantly improved MFT, PASS and FRT (p<0.05). Also, there were significantly differences in MFT, and PASS between the groups. [Conclusion] Somatosensory training for the hand influenced hand function and postural control. Therefore, we consider that somatosensory function plays a major role in hand and postural control.
