The TLSO was customized for this study in OO ortho-prosthesis institute from Jan. 1th., 2000 to Dec. 31th., 2000 and in order to measure effects of TLSO. 20 females in a growth period applicable to medical care took part in this study, they were on accidental spine scoliosis (From $15^{\circ}to35^{\circ}$). They were consisted of Group I(10 chest-bend) and Group II (10 dual-bend). The results were follows: 1. It showed the average difference in height by 1.37cm, 3.14cm in comparison between before and after TLSO, before and after one year and they were also statistically available(p < .05). 2. It showed the average difference in Cobb angle of a chest and waist by ($-10.95^{\circ},-8.50^{\circ}$), between before and right after TLSO. The results means that the Cobb angle of the chest and weist at right after TLSO was largely decreased, and it was also statistically available(p < .05). 3. It showed the difference in Cobb angle of the chest waist by $-9.50^{\circ},-7.35^{\circ} $ between before and one year after TLSO. It means that the Cobb angle of the chest and waist at the one year after TLSO was largely decreased, and it was also statistically available(p < .05). 4. It showed the difference in Cobb angle of the chest and waist by $2.34^{\circ},2.15^{\circ} $ between the right after and the one year after. TLSO, but the change of Cobb angle of the chest was regularly constant by a little increased, and it was also statistically available(p < .05). 5. In the measurement of the change of Cobb angle of the chest and waist according to the taking time on TLSO, it showed the slightest change in 10 people on TLSO for 23 hours by $13.30^{\circ},11.20^{\circ}$ , the change in 6 people on TLSO for 16 hours by $14.75^{\circ},12.67^{\circ}$, the change in 4 people on TLSO for 8 hours by $16.83^{\circ},14.00^{\circ} $ in this order. It means that the longer time on TLSO was to be the smaller the Cobb angle of the chest and waist, but it was not statistically available.

Purpose: Rehabilitative devices are used to enhance sensorimotor training protocols, for improvement of motor function in the hemiplegic limb of patients who have suffered a stroke. Sensorimotor integration feedback systems, included with these devices, are very good therapeutic frameworks. We applied this approach using electrical stimulation in stroke patients and examined whether a functional electric stimulation-assisted biofeedback therapy system could improve function of the upper extremity in chronic hemiplegia. Methods: A prototype biofeedback system was used by six subjects to perform a set of tasks with their affected upper extremity during a 30-minute session for 20 consecutive working days. When needed for a grasping or releasing movement of objects, the functional electrical stimulation (FES) stimulated the wrist and finger flexor or extensor and assisted the patients in grasping or releasing the objects. Kinematic data provided by the biofeedback system were acquired. In addition, clinical performance scales and activity of daily living skills were evaluated before and after application of a prototype biofeedback system. Results: Our findings revealed statistically significant gradual improvement in patients with stroke, in terms of kinematic and clinical performance during the treatment sessions, in terms of manual function test and the Purdue pegboard. However, no significant difference of the motor activity log was found. Conclusion: Hemiplegic upper extremity function of a small group of patients with chronic hemiparesis was improved through two weeks of training using the FES-assisted biofeedback system. Further research into the use of biofeedback systems for long-term clinical improvement will be needed.

Objective To describe a hand-stretching device that was developed for the management of hand spasticity in chronic hemiparetic stroke patients, and the effects of this device on hand spasticity. Methods Fifteen chronic hemiparetic stroke patients with finger flexor spasticity were recruited and randomly assigned to an intervention group (8 patients) or a control group (7 patients). The stretching device consists of a resting hand splint, a finger and thumb stretcher, and a frame. In use, the stretched state was maintained for 10 minutes per exercise session, and the exercise was performed twice daily for 4 weeks. Spasticity of finger flexor muscles in the two groups was assessed 3 times, 4 weeks apart, using the Modified Ashworth Scale (MAS). Patients in the intervention group were assessed twice (pre-1 and pre-2) before and once (post-1) after starting the stretching program. Results Mean MAS (mMAS) scores at initial evaluations were not significantly different at pre-1 in the intervention group and at 1st assessment in the control group (p>0.05). In addition, no significant differences were observed between mMAS scores at pre-1 and pre-2 in the intervention group (p>0.05). However, mMAS scores at post-1 were significantly lower than that at pre-2 in the intervention group (p<0.05). Within the control group, no significant changes in mMAS scores were observed between 1st, 2nd, and 3rd assessments (p>0.05). In addition, mMAS scores at post-1 in the intervention group were significantly decreased compared with those at the 3rd assessment in the control group (p<0.05).Conclusion The devised stretching device was found to relieve hand spasticity effectively in chronic hemiparetic stroke patients.

This study proposed the design of a prosthetic finger that can perform functions, such as motion and gripping, without patients (with amputated fingers) needing an additional actuator. The contributions and contents of this study are as follows: First, the structure of a prosthetic finger, which could be operated by the patient’s own volition without an external actuator, was introduced. Second, the mathematical relationship for effectively designing the proposed structure was explained. In addition, by using this mathematical relationship, the trend of the fingertip trajectory, according to the link length and angle (the design variables) was analyzed. Through this analysis, an optimal design was achieved to determine the link length at which the root mean square error with the target trajectory was minimized. Third, a design method reflecting the finger size and anatomical structure was proposed. Finally, using the fabricated prototype, the proposed design was tested, and the prosthetic finger, having free motion and the ability to grip objects of various sizes, was experimentally verified.
