The aim of this study was to investigate the effects of treadmill gait training on the functional characteristics and the temporal-distance parameters of gait in hemiplegic patients, as compared with conventional gait training. The subjects of this study were 32 hemiplegic patients who had been admitted or were visited out-patients at Kangdong Sacred Heart Hospital, Hallym University, from March 3 through April 25, 2003. These subjects were randomly divided into treadmill gait training group or conventional gait training group. We evaluated the gait ability, motor functions, muscle strength, spasticity, physiological cost index, and temporal-distance parameters. We analyzed the changes between pre and post training in each groups, and the difference between two groups. Temporal-distance parameters were obtained using the ink footprint method and then energy consumption using physiological cost index. The results were as follows: 1. After a six-week training, treadmill gait training group significantly improved, as. compared to pre-training, in gait ability, motor functions for the leg and trunk and gross function, muscle strength of the lower limb, gait speed, cadence, step length both on the affected and on the unaffected side, step length symmetry, and energy consumption(p<0.05). 2. After a six-week training, conventional gait training group significantly improved, as compared to pretraining, in gait ability, motor functions for the leg and trunk, muscle strength of the lower limb, spasticity the upper limb, gait speed, cadence, step length both on the affected and on the unaffected side, and energy consumption(p<0.05). 3. After a six-week training, the treadmill gait training group significantly improved, as compared to the conventional gait, training, in gait speed and step length on the unaffected side. These results show that treadmill gait training was improved gait speed and step length on the unaffected side of hemiplegic patients, as compared with conventional gait training. Further research is needed to confirm the generalization of these findings and to identify which hemiplegic patients might benefit from treadmill gait training.

Purpose: Hemiplegia patients who were attacked by a stroke suffer from hemiplegic disabilities as well as motor disabilities. For them, rehabilitation cure is being carried out broadly. However, it is not enough for them to use the upper extremity than the lower extremity. For the use of the upper extremity, we examined the effect of constraint-induced movement therapy developed in this research on patients who experienced a stroke following hemiplegia. Method: For this study we selected 36 stroke patients who were registered at the community health center through accidental sampling, and assigned 21 of them to the experimental group, and 15 to the control group. The experimental group had constraint-induced movement therapy for 5 days and 7 hours a day from 9 to o'clock in the morning 9 to 4 o'clock in the afternoon 4 including warmup exercise and main exercise in the rehabilitation room, whereas the control group were restricted. Result: As a result of constraint-induced movement therapy, affected side elbow joint flexion range, side shoulder joint extension range and side shoulder joint of the flexion range of motions increased obviously in the experimental group compared to those in the control group. Conclusion: The result above clearly shows that constraint-induced movement therapy is an effective intervention for the rehabilitation of hemiplegia patients in increasing affected side elbow joint of the flexion range of motion, the shoulder joint extension, and the increase of flexion range of motion.

The purpose of this study was to investigate the influence of physical functions of elderly people on their clothing behavior and to provide basic information about manufacturing comfortable apparels for the elderly. A total of 219 people, with ages between 60s and 70s, participated in the survey and in the experiment to correlate their tendency of wearing clothes with the state of their physical functions. About 78.5% of the elderly showed eyesight deterioration in the subjective evaluation. Elders in their 60s raised their arms higher up in overhead reach, and showed shorter distance between middle fingertips in behind back stretch and in back scratch than elders in their 70s. Also, the former stretched farther to the floor in standing trunk flexion, and maintained more steady in one leg stand and in tandem stance than the latter. The narrower the movement range of the upper limb joints was, the more the elderly preferred upper garments with full front opening to those with half or no opening. The more inflexible the upper limbs and waist and the more unbalanced the body was, the more likely the elderly put on pants while sitting on the floor. The time taken to button up the shirt and to put on and take off pants showed a positive correlation with the overhead reach, the behind back stretch, the back scratch and the standing trunk flexion, whereas the former showed a negative correlation with the one leg stand and the tandem stance.

Background: Tourniquet pain has important impacts on anesthesia. Tourniquet pain and accompanying cardiovascular changes are important factors that make patients in distress during anesthesia. As tourniquet pain may be modified by anesthesia, a study on the changes in the neural functions by tourniquet inflation in normal volunteers is important. Methods: Time-dependent changes in tourniquet pain, heart rate, phantom limb sensation, motor function, pain to pressure on upper extremity of 10 healthy and unpremedied volunteers were measured. Each parameter were measured every 5 minutes starting from 10 minutes before inflation to 15 minutes after deflation of tourniquet. Tourniquet was deflated when the subject felt unbearable pain (score 100 with visual analog scale). Results: Subjects manifested time-dependent pain responses to tourniquet inflation, characterized by increase in VAS, systolic and diastolic blood pressure. Mean duration of tourniquet inflation was 36.4 minutes, volunteers experienced motor paralysis at 27.6 minutes and sensory loss at 33.1 minutes. Pain to pressure decreased over time in both arms. The degree of decrease was greater in the arm on which tourniquet was applied than that in the non-applied arm. Phantom limb sensation occurred in 3 subjects. Conclusions: This study demonstrated dynamic changes in the neural functions during tourniquet inflation period. Tourniquet-induced pain and resultant hypertension occurred in all subjects. Appropriate anesthetic management is needed for the surgery using tourniquet.

The purpose of this study was to investigate the effect of Modified Constraint-Induced Therapy (MCIT) on the effected upper extremity of children with hemiparesis. Four children with hemiparetic upper extremity caused by brain injuries were trained by MCIT for ten weeks. During the same period, all of the subjects were also involved in thirty-minute regular physical therapy and occupational therapy. During the treatment period, the unaffected upper extremities of the subjects were restrained by a specially designed hand splint or a mitten for five hours a day, five days per week. For two hours out of the five-hour restraint period, the affected upper extremities were intensively trained by performing various functional tasks, which were individually structured to emphasize use of the affected arm. A single-subject design with A-B-A reversal was employed in this study. The affected limb motor ability was evaluated by Melbourne Assessment, measuring the time to grasp and release nine pegs, and measuring grasping power. As a consequence of this study, the affected limb motor test scores of all four subjects in the baseline period were improved during the treatment period. Furthermore, the treatment effect was maintained during a one-month follow-up period. The results of this study support the assumption that MCIT is an effective therapeutic method to improve the sensory and motor abilities of hemiparetic children. It also increases the frequency of functional use of the hemiparetic hands of brain-injured children. Based on the results of this study, it can also be assumed that the modified CIT method is especially beneficial to these children by reducing the negative emotional effects of forceful restraint of the unaffected upper extremity. To optimize the functional recovery of the paretic upper extremity by CIT, the restriction period per day should be decided individually, according to the characteristics of the individual.

The redundancy resolution of the seven DOF (Degree of Freedom) upper limb exoskeleton is key to the synchronous motion between a robot and a human user. According to the seven DOF human arm model, positioning and orientating the wrist can be completed by multiple arm configurations that results in the non-unique solution to the inverse kinematics. This paper presents analysis on the kinematic and dynamic aspect of the human arm movement and its effect on the redundancy resolution of the seven DOF human arm model. The redundancy of the arm is expressed mathematically by defining the swivel angle. The final form of swivel angle can be represented as a linear combination of two different swivel angles achieved by optimizing two cost functions based on kinematic and dynamic criteria. The kinematic criterion is to maximize the projection of the longest principal axis of the manipulability ellipsoid of the human arm on the vector connecting the wrist and the virtual target on the head region. The dynamic criterion is to minimize the mechanical work done in the joint space for each of two consecutive points along the task space trajectory. The contribution of each criterion on the redundancy was verified by the post processing of experimental data collected with a motion capture system. Results indicate that the bimodal redundancy resolution approach improved the accuracy of the predicted swivel angle. Statistical testing of the dynamic constraint contribution shows that under moderate speeds and no load, the dynamic component of the human arm is not dominant, and it is enough to resolve the redundancy without dynamic constraint for the realtime application.
