Objectives: We investigated muscle force from the upper limb lifting resistance test to conform the objectivity in manual muscle test. Methods: We made standard method in upper limb lifting resistance test to compare with experiment method switching the lower limb position left & right. And resistance forces of upper limb of subject were checked to inspector with closing eyes. Results: 1. The lifting resistance of right upper limb was stronger when the lower limb of right and left were abducted. 2. The lifting resistance of right upper limb was weaken when the lower limb of right and left were adducted. 3. The lifting resistance of right upper limb was weaken when the lower limb of right and left were elevated. Conclusions: As the above results, the deltoid muscle force checked in the upper limb lifting resistance test is affected by the location of lower limbs, it suggested that the muscle force of some part in the body will be affected by the other parts. It will be useful to understand the symmetry principle of body in muscle function.

The purpose of this study was to investigate the convergence effect of focal vibration stimulation and bilateral upper limb training on the recovery of upper limb function when applied to stroke patients. For 20 stroke patients, divided into an experimental group that performed convergence intervention with focal vibration stimulation and bilateral upper limb training, and a control group who performed only bilateral upper limb training. It was conducted 20 times for 4 weeks, 30 minutes per session. Vibration stimulation was applied to the affected side of the experimental group for 30 minutes during training. Results were measured for the degree of recovery of the affected upper limb function, amount of use on the affected and unaffected sides, the quality and satisfaction in performance on use of both upper limbs. Comparisons were made within groups using a paired-sample t-test and between groups using covariance analysis. As a result of the study, the experimental group showed a significant difference in dexterity and the amount of use on the affected than the control group. The effect size was more than the small effect size in all evaluation items. Through this study, it is thought that the convergence intervention of focal vibration stimulation and bilateral upper limb trainingcan be used clinically as an effective intervention for the recovery of arm function in stroke patients.

The purpose of this study was to investigate difference between grip strength, upper limb dexterity, and hand function according to touch and heat sensory stimulus. Forty healthy men were recruited. After obtaining subjects characteristics, examined grip strength, upper limb dexterity, and hand function, then we made touch sensory input using soft brush and tried the test again. Next day, we made thermal input using hot pack and did retest, too. The result showed significant differences appeared on every variable in grip strength and upper limb dexterity test (p<.001), and significant differences appeared on every variable except lifting small objects in hand function (p<.01). In conclusion, sensory input is to increase grip strength, upper limb dexterity, and hand function. The thermal sensory input has a tendency to increase grip strength, upper limb dexterity, and hand function than that of touch sensory input in effect of stimulus classification. The application of proper stimulus helps to facilitate upper limb and hand function in rehabilitation and in industrial field. So it is necessary to try more tests of frequency and intensity of stimulus.

Background: Motor imagery is the mental representation of an action without overt movement or muscle activation. However, few previous studies have demonstrated motor imagery training effects as an objective assessment tool in patients with early stroke. Objective: To investigate the effect of motor imagery training on Somatosensory Evoked Potentials (SSEP) and upper limb function of stroke patients. Design: A quasi-experimental study. Methods: Twenty-four patients with stroke were enrolled in this study. All subjects were assigned to the experimental or control group. All participants received traditional occupational therapy for 30 minutes, 5 times a week. The experimental group performed an additional task of motor imagery training (MIT) 20 minutes per day, 5 days a week, for 4 weeks. Both groups were assessed using the SSEP amplitude, Fugl-Meyer assessment of upper extremity (FMA UE) and Wolf motor function test. Results: After the intervention, the experimental group showed significant improvement in SSEP amplitude and FMA UE than did the control group. Conclusion: These findings suggest that the MIT effectively improve the SSEP and upper limb function of stroke patients.

Most partial hand amputees experience limited wrist movement, which hinders the efficient functioning of upper limb, affecting hand-to-use coordination and the usability of the prosthetic hand. This limitation can lead to secondary musculoskeletal issues due to repetitive compensatory movement patterns. However, current partial hand prosthetic lack rotational wrist movement due to challenges in accommodating various hand shapes and limited space. In our study, we proposed a prosthetic hand with a wrist rotation module for partial hand amputees, aiming to reduce compensatory movement. To validate the proposed wrist rotation module, we conducted motion analysis during reach-to-grasp task. Furthermore, during the Jebsen-Taylor hand function test, we evaluated both the effect on upper limb movement and the usability of the prosthetic hand, comparing configurations with and without the wrist rotation module. The results showed that the prosthetic hand equipped with rotational wrist movements reduces compensatory movements and promotes efficient upper limb movement patterns. This finding highlights the value of incorporating a wrist rotation module in prosthetic hands to improve upper limb movement for partial hand amputees.

Purpose : To assess the relationship between post-stroke shoulder pain, motor function, and pain-related quality of life(QOL) Methods : Volunteer sample of 62 chronic stroke survivors with post-stroke shoulder pain and glenohumeral subluxation. The patients answered the question in shoulder pain with the Brief Pain Inventory question 12 (BP1-12), Pain-related Quality of life(BPI-23). Therapists measured the performance of combined upper-limb movement including the hand-behind-neck(HBN), hand-behind-beck(HBB) maneuver, added passive pain-free shoulder external rotation range of motion, and Modified Ashworth Scale(MAS) score of the elbow flexors. Physical performance assessments were used to measure basic activity daily living(Modified Barthel Index-self care, MBI-S/C), motor function of upper limb(Fugl-Meyer Upper/Lower Extremity, FM-U/E). Results : Stepwise regression analyses indicated that post-stroke shoulder pain is associated with the BPI 23, but not with the FM-U/E, MBI-S/C. Thus, the presence of shoulder pain is more important predicting pain-related QOL than its degree in predicting motor function of upper limb and basic activity daily living. Conclusion : Post-stroke shoulder pain was associated with reduced quality of life related to pain. The pain was not associated with the motor function of upper limb and basic activity daily living. The result imply that management of shoulder pain & anatomical position of shoulder joint after stroke should be emphasized. This provides a further incentive to develop effective rehabilitation prevention and treatment strategies for post-stroke shoulder pain.

The purpose of this study was to determine the effect of lower extremity strengthening program on balance, gait and upper limb function in patients with stroke. This study was a hospital-based with Central nerve system lesion patients, randomized controlled trial with a blinded assessor. Twenty four hemiparetic stroke patients were divided into two groups: a Lower extremity strengthening program group (LESPG)(n=12) and a Treadmill training group (TTG)(n=12). The LESPG performed a Lower extremity strengthening program on the affected side. The TTG exercised on a treadmill for 30 minutes a day. Assessment tools included the Timed Up and Go test (TUG), the Functional Gait Assessment (FGA) and the Manual Function Test (MFT). There was a significant difference in TUG, FGA, and MFT scores between the two groups in the LESPG for the balance, gait, and upper limb function than for the TTG(p<.01). Results of the present study indicated that the effect of lower extremity strengthening program for 4 weeks had an effect on balance, gait and upper limb function of hemiplegic patients after stroke.

Purpose: The purpose of this study was to investigate the effects of forward-and-backward shift trunk exercise using a proprioceptive neuromuscular facilitation (PNF) diagonal pattern in a closed kinematic chain exercise on the upper limb function and activity of daily living (ADL) in a stroke patient. Methods: One subject participated in this study. The study used a reversal A-B-A' design, where A and A' were the baseline period (no intervention), and B was the intervention period. The intervention was a forward-and-backward trunk shift exercise, using a PNF diagonal pattern on both a stand-on-hand position and a quadruped position of closed kinematic chain exercises, for 20 min per day for 2 weeks. The range of motion (ROM) of the shoulder joint was measured and a Fugl-Meyer assessment of upper extremity (FMA-UE) and a functional independence measure (FIM) were performed to measure upper limb function and activity of daily living (ADL). Results: ROMs of shoulder joint (flexion, extension, abduction, and external rotation) increased in the intervention phase. The FMA-UE score increased (from 28 to 36) in the intervention phase. The FIM score increased (from 20 to 25) in the intervention phase. These increases were maintained after intervention (Baseline II). Conclusion: These results suggest that forward-and-backward shift trunk exercises using a PNF diagonal pattern in a closed kinematic chain exercise have a positive effect on stroke patients' upper limb function and ADL ability.

Rehabilitation of upper limb motor function of hemiplegic patient must maintain interest and demand a device for a quantitative evaluation of rehabilitation training. In this paper, we developed the device that is composed of arm cradle, handle, and balance ball for rehabilitation exercise. We have performed experiment for validity as to whether to use the rehabilitation device when tilting the upper extremity training device developed to measure changes in the EMG signal to the main upper limb muscles for 7 healthy volunteers. We have analyzed muscle activation signals on agonist and antagonist as a reference in the muscle contraction and relaxation in the upper limb extension and flexion when the balance-handle device is tilted to front-rear and left-right. The experimental results showed that a tendency of muscle activation of biceps, triceps, and deltoid used in upper limb motor function of hemiplegic patients from extension and flexion evaluation items of Fugl-Meyer Assessment(FMA). These results may be helpful for rehabilitation training for upper limb motor function of hemiplegic patients by utilizing a developed unit.
