Purpose: The purpose of this study was to determine the effect of a 2-week somatosensory stimulation program on cognitive function and ADL of patients with brain damage. Methods: The sample consisted of two groups of patients with stroke: 10 patients with a mean age of 59.0 years who were treated with somatosensory stimulation, and 9 patients with a mean age of 51.78 years, who were not treated with somatosensory intervention. A nonequivalent control group non-synchronized design was used to assess the functional recovery after stroke. Instruments used in this study were MMSE-K for cognitive function and FIM for ADL. Results: The hypothesis 1 that "Patients with stroke who were treated with the somatosensory stimulation program will show higher MMSE-K score than that of the non-treatment group" was supported(Z = -2.390, p = .017). The hypothesis 2 that "Patients with stroke who were treated with the somatosensory stimulation program will show higher FIM score than that of the non-treatment group", however, was partially supported(social cognition: Z = -2.204, p = .045). Conclusion: Somatosensory stimulation was effective to patients with stroke in improving their cognitive function. These findings suggest that somatosensory input can be adopted to nursing intervention for functional recovery after stroke.

Purpose: The purpose of this study was to determine the effect of a 3-week somatosensory stimulation program on the integrity of the somatosensory pathway of patients with brain damage. Method: The sample consisted of two groups of patients with brain damage matched by Glasgow Coma Scale (GCS) scores and age:8 patients with a mean age of 56.75 years who were treated with somatosensory stimulation, and 8 patients with a mean age of 58.88 years, who were not treated with sensory intervention program. A repeated measures matched-control group design was used to assess functional recovery of the brain. The instrument used in this study was SSEP (somatosensory evoked potentials), a neurophysiological parameter, for the integrity of the somatosensory pathway. Results: The hypothesis that patients with brain damage who were treated with the somatosensory stimulation program will show higher SSEP wave form scores than the non-treatment group was supported (3rd week.: U=13.000, p=.014). Additional repeated measures analysis showed that there were no significant differences in recovery trends between the groups (F=1.945, p=.159). Conclusion: This study demonstrates that a somatosensory stimulation program is effective in promoting recovery of the integrity of the somatosensory pathway of patients with brain damage.

Evoked potentials(EP) are defined as electric responses of the nerves system to sensory stimulation. EPs are used mainly to test conduction in the visual, auditory, and somatosensory systems, especially in the central parts of these systems. Somatosensory evoked potentials (SEP) are the potentials elicited by stimulation of peripheral nerves and recorded at various sites along the sensory pathway. SEPs types consist mainly of SEPs to electric stimulation of arm or leg nerves. SEPs to arm stimulation are usually recorded simultaneously from clavicular, cervical, and scalp electrodes; SEPs to leg stimulation are recorded from lumbar, low thoracic, and scalp electrodes. Subject variables that have practical impotance are age, limb length, body height, and temperature. General clinical interpretation of abnormal SEPs wave decreases of peripheral conduction time, and abolition of SEPs recorded from different levels to identify lesions of peripheral nerves, plexus, nerve root, spinal cord, cauda equina, hemispheric brainstem, and cerebral parts of the somatosensory pathway.

본 문헌고찰의 목적은 뇌졸중을 경험하는 대상자들을 위한 체성감각 자극 중심치료의 효과와 관련된 지금까지의 문헌들을 확인하고, 본 문헌고찰에 근거하여 임상환경에서 보다 효과적으로 적용할 수 있는 이상적인 체성감각자극 훈련방법을 제안하고자 함이다. 먼저, 문헌연구를 통해 뇌졸중을 경험하는 대상자를 중심으로 지금까지 주로 적용되었던 전기적 체성감각자극 치료의 효과성과 제한점을 확인하고, 최근문헌에 근거하여 임상환경에서 보다 효율적 적용이 가능할 것으로 기대되는 앞으로의 치료적 발전방향성을 제시하였다. 본 문헌고찰 결과, 현재까지 뇌졸중을 경험하는 대상자의 기능회복을 위한 체성감각 중심훈련의 필요성을 강조하는 연구 결과가 어느 정도 축적되어 있었음에도 불구하고 실제 임상에서는 재활치료 시 치료적인 여건에 제한으로 인해 구체적인 체성감각 자극입력의 치료적 적용은 제한점이 많은 것으로 확인되었다. 뿐만 아니라, 현재 이용 되고 있는 치료도구 역시 체성감각 및 특수감각을 고려한 도구는 거의 없는 것이 현실이었다. 하지만 본 문헌고찰을 통해서 분명히 확인할 수 있었던 것은 적절한 체성감각과 특수감각의 통합적 적용은 뇌졸중을 경험하는 대상자의 기능회복에 매우 긍정적인 효과를 보여주었다는 점이다. 뿐만 아니라, 치료적 환경에서 적용 가능한 적절한 기계적 인터페이스의 적용은 향후 뇌 손상 환자의 재활에 매우 긍정적인 영향을 줄 수 있을 것이라고 기대된다.

Purpose: This study examined the improved sensory, hand function, postural balance and activities of daily living (ADL) through somatosensory stimulation, such as the facilitation of functional reaching and tactile, proprioceptive stimulus of the upper limb (UL) and hand. Methods: Seventeen stroke patients having problems with motor and somatosensory deficits were selected in Bobath Memorial Hospital adult rehabilitation center. The patients were divided into two groups; the sensorimotor deficit group (SMDG) and motor deficit group (MDG). Somatosensory stimulation on the UL, physical therapy and occupational therapy were carried out three times a week over a six week these treatments were performed in both group period. To compare each group, the following assessment tools were used: such as tactile detection thresholds (TDT), two point discrimination on the affected side (TPDas), unaffected side (TPDus) stereognosis (ST) manual function test, hand function on the affected side (HFas) and unaffected side (HFus), Postural Assessment Scale for Stroke (PASS) and Korean version Modified Barthel Index (K-MBI). Results: In the SMDG, somatosensory stimulation on the UL was statistically important for TDT, TPDas, TPDus (except for the thener), ST, hand function on HFas, on HFus, PASS length of displacement with foam (LDFSEO), and K-MBI. In the MDG, somatosensory stimulation on the UL was important for TDT, TPDas, TPDus (except index finger) length of displacement with the eyes open, LDFSEO, HFas, HFus, PASS and K-MBI. In addition, there was a significant difference in the PASS between SMDG and MDG. Conclusion: Somatosensory stimulation on the UL affects the sensory, hand function, postural control and ADLs performance.

In the present study, to examine the effects of somatosensory stimulation of the hands on the hand functions and visuomotor coordination of children with developmental disabilities, a total of 24 sessions of experiments were conducted with three children with developmental disabilities for 60 minutes per session, three sessions per week from January 7, 2013 to March 11, 2013. To examine the effects of somatosensory stimulation of the hands on grasping and visuomotor coordination which are sub-areas of PDMS-2, the A-B study design was used which is a single case study method out of single-subject experimental research designs. Somatosensory stimulation of the hands was shown to be effective in improving the hand functions of children with developmental disabilities. Somatosensory stimulation of the hands showed positive effects on the raw scores and standardized scores of grasping and visuomotor coordination in all the three subject children. Visuomotor coordination functions showed higher scores in post-hoc tests in all three children. In particular, ring throws showed high scores at right $90^{\circ}$, right $45^{\circ}$, center, left $45^{\circ}$, and left $90^{\circ}$ among visual directions. In the present study conducted with children with developmental disabilities, ring throws were performed to examine visuomotor coordination. In particular, the numbers of successes of ring throws on the front, left, and right were shown to be high. Therefore, somatosensory stimulation of the hands was effective on the hand functions and visuomotor coordination functions of children with developmental disabilities.

The purpose of this study was to investigate lower-limb joint torque of the two groups as it changed by somatosensory stimulation during the descent down three stairs of different heights and to describe the difference between the two groups, which are young people group and elderly people group. Subjects of each groups climbed down a stair at four stimulation conditions, which are non-stimulation, tibialis anterior tendon stimulation, achilles tendon stimulation, tibialis anterior - achilles tendon stimulation. Motion capture data were collected using 3D optoelectric motion tracking system that utilizes active infrared LEDs, near infrared sensor and force plate. The obtained motion capture data was used to build 3D computer simulation model. The results show that lower-limb joint torque of the two groups changed with somatosensory stimulation as they descended the stairs and the joint torque of the two groups differed from each other.

This paper proposes a somatosensory stimulation system for the improvement of postural stability using vibration as somatosensory stimulation. This system consists of vibratory stimulation and postural response measurement. To evaluate this system, the center of pressure(COP) was closely observed in turn with simultaneous or separate mechanical vibratory stimulations to flexor ankle muscles (tibialis anterior, triceps surae) and two plantar zones on both feet while standing on a stable and an unstable support. The simultaneous vibratory stimulations cleared influenced postural stability and the effects of vibrations were higher with the unstable support. In separate vibratory stimulations, the extent of the COP sway reduced when the direction of the vibratory stimulations and that of the inclination of body coincided for flexor ankle muscle stimulations. In the contrary, the extent of the COP sway increased when the direction of the stimulations and that of body inclination coincided for plantar zone stimulations. These results can be useful for the development of rehabilitation systems that utilizes somatosensory inputs for postural balance.

Purpose : This study aims to investigate the effect of somatosensory stimulation on the upper limb sensory and function and self-esteem of stroke patients. Methods : This study period was march 4 to april 4 (5 weeks). The subject were 20 stroke patients with somatosensory impairment in B hospital, seongnam, gyeonggi province. They were devided into two group-experimental and control-with 10 members each. The members of the experimental group underwent somatosensory stimulation, whereas the members of the control group underwent an occupation-based intervention for 5 weeks. Thirty-minute therapy was provided 3 times per week for 5 weeks. Before and after the intervention, both groups were evaluated via light touch, static two-point discrimination, stereognosis, Fugl-Meyer assessment (FMA), and self-esteem scale Results : In this study, light touch was not significant in both groups. Static two-point discrimination was significant among the experimental group member's index fingers. Among the control group members, it was significant in the ring finger. The comparison between the two groups was significant in the index finger. The stereognosis results were significant in the experimental group but not in the control group. The comparison between the groups after the intervention was not significant. FMA was significant in the shoulder/ elbow/ forearm (SEF), hand and coordination among the experimental group. Among the control group, it was significant in the SEF and hand. The comparison between the groups was significant in the SEF, hand and coordination. The self-esteem scale results were significant among both groups, and the comparison between the group's score was likewise significant. Conclusion : In conclusion, somatosensory stimulation therapy increases the static two-point discrimination, stereognosis, upper extremity function, and self-esteem of patients with stroke. Therefore, while somatosensory stimulation therapy is not the best therapy, it is one of the best occupational therapies for stroke patients.

Purpose: Sensory input is very important for proper performance of human. Two-point discrimination is the most widely used tactile sensory test. The purpose of this study was to find the changes in cortical activation patterns between tactile stimulation and two-point discrimination. Methods: Two healthy subjects participated in our study. fMRI scanning was done during 4 repeated blocks of tactile stimulation and two point discrimination of the right index finger tip. In one block, stimuli were repeated 10 times every three seconds. To determine the changes of cortical neurons during sensory input, intensity index was analyzed. Results: When tactile stimulation of the right index finger tip was completed, only contralateral primary somatosensory area was activated. In contrast, during two-point discrimination, both the primary somatosensory area and ipsilateral supplementary sensory area were activated. Conclusion: During two point discrimination, both primary somatosensory area and ipsilateral supplementary sensory area were activated. Therefore, two-point discrimination is required more complex and conscious activity than tactile stimulation.
