The aim of this study was to investigate effects of reaching distance on movement time and trunk kinematics in hemiplegic patients. Eight hemiplegic patients participated in this study. The independent variables were side (sound side vs. affected side) and target distance (70%, 90%, 110%, and 130% of upper limb). The dependent variables were movement time measured by pressure switch and trunk kinematics measured by motion analysis device. Two-way analysis of variance with repeated measures was used with Bonferroni post-hoc test. (1) There were significant main effects in side and reaching distance for movement time (p=.01, p=.02). Post-hoc test revealed that there was a significant difference between 110% and 130% of reaching distance (p=.01). (2) There was a significant main effect in side and reaching distance for trunk flexion (p=.01, p=.00). Post-hoc test revealed that there were significant differences in all pair-wise reaching distance comparison. (3) There was a significant side by target distance interaction for trunk rotation (p=.04). There was a significant main effect in target distance (p=.00). Post-hoc test revealed that there were significant differences between 70% and 110%, 70% and 130%, 90% and 110%, 90% and 130% of target distance. It was known that trunk flexion is used more than trunk rotation during reaching task in hemiplegic patients from the findings of this study. It is also recommended that reaching training is performed with limiting trunk movement within 90% of target distance whereas reaching training is performed incorporating with trunk movement beyond 90% of target distance in patients with hemiplegia.

Objective: This study aimed to quantify one of the useful upper extremity movements to evaluate motor control abilities between the groups of people with mild and moderate arm impairments performing a door handling task. Design: Cross-sectional study. Methods: Twenty-one healthy participants and twenty-one persons with chronic stroke (9 mild stroke and 12 moderate stroke) were recruited for this study. Stroke participants were divided into 2 groups based on Fugle-Meyer Assessment scores of 58-65 (mild arm) and 38-57 (moderate arm). All they performed door handling task including the pronation and supination phases 3 times. We measured some movement factors which were reaction time, movement time, hand of peak velocity, hand of movement units to perform door handling task using the three-dimensional motion analysis. Results: The majority of kinematic variables showed significant differences among study groups (p<0.05). The reaction time, total and phase of movement time, hand of peak velocity, the number of movement units discriminated between healthy participants and persons with moderate upper limb stroke (p<0.05). In addition, reaction time, total and phase of movement time, the number of movement units discriminated between those with moderate and mild upper limbs of stroke patients (p<0.05). Conclusions: Three-dimensional kinematic motion analysis in this study was a useful tool for assessing the upper extremity function in different subgroups of people with stroke during the door handling task. These kinematic variables may help clinicians understand the arm movements in door handling task and consist of discriminative therapeutic interventions for stroke patients on upper extremity rehabilitation.
A skier's motion was analyzed by a simple model consist of point mass m and a single rod connected to a single ski plate. We studied the conditions for the stable ski turn as functions of the linear velocity and the radius of the turn. The solutions for the stable ski turn in our model do not require any extra skier's movement to complete a stable circular turn. The solution may then give the skier the most comfortable skiing method without any active movement to control the ski. The generalized force supporting the point mass from the ski plate was calculated. We obtained the force from the ground (rebound force) without any geometrical structure of the ski plate. Adding an active movement to the direction of the ski plate, the conditions for the stable ski turn were also analyzed. Our result gives some insight for the skier who wants to develop technique.

Background: Lateral epicondylitis is the most common complaint with complex etiological and pathophysiological factors on the lateral side of elbow. Taping techniques commonly used for lateral epicondylitis. The purpose of this study was to investigate the effects of mobilization with movement taping and diamond taping on the pain, grip strength and functional activity in patients with lateral epicondylitis Methods: Twenty patients with lateral epicondylitis (mobilization with movement taping group: n=10, diamond taping group: n=10) were recruited. They were evaluated pre-treatment, after 1weeks, and after 3weeks, using visual analog scale, pain free grip strength test, patient-rated tennis elbow evaluation. Results: Analysis showed statistcally significant improvement in all time in both groups. and The mean improvement in pre-1weeks visual analog scale was significantly greater in the Diamond taping group than that in the mobilization with movement taping group. and the mean improvement in pre-1weeks pain free grip strength test was significantly greater in the mobilization with movement taping than that in the diamond taping group. Conclusion: Taping technique to patients with lateral epicondylitis can help improve pain, grip strength, functional activity and initial taping technique can be selected depending on the patient's condition and the desired goal.
This study wan described the movement patterns when rising from supine to erect stance in the third through eighth decades. Two hundred fifty six subjects, ranging in age from 30 year to 89 were filmed while rising from a supine position. Movement patterns were classified using categorical descriptions of the action of the upper and lower extremity, head-trunk region. This study was designed to determine whether within the rising task the movement patterns of different regions of the body vary with age level and sex, to describe time by subjects to perform this task. The incidence of each movement pattern was calculated and graphed wi th respect to age level and sex. Erect standing time was increased by age increasing in beth sex group. The most common form of rising for subject in the third through fifth decades both sex usually involved symmeytrical push with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern wi th head-trunk and symmetrical push to push and reach pattern with upper extremity, symmetri cal squat pattern with lower extremity. partial rotation with head-trunk. In the sixth through eighth decades usually involved symmetrical push to push and reach pattern with upper extremity, symmetrical squat pattern with lower extremity, partial rotation pattern with head-trunk in both sex group.
Purpose: The study investigated the effects of extracorporeal shock wave therapy with myofascial release techniques (ESWT+MFR) on pain, movement, and function in patients with myofascial pain syndrome. Methods: Forty participants with upper trapezius trigger points were recruited and randomly allocated to two groups: an experimental group (n = 20) and a control group (n = 20). The experimental group performed the ESWT+MFR, and the control group performed only myofascial release techniques. Each group was treated for 15 minutes, twice a week for four weeks. Pain was assessed using a visual analogue scale and a pressure pain threshold measure. Movement was assessed by cervical range of motion, and cervical and shoulder function were assessed on the Constant-Murley Scale and the Neck Disability Index before and after treatment. Results: The results indicate statistically significant improvements in the two groups on all parameters after intervention as compared to baseline (p < 0.05). As compared to the control group, the experimental group showed statistically significant improvements on the visual analogue scale and pressure pain threshold, cervical range of motion (except rotation), and on the Neck Disability Index (p < 0.05). Conclusion: The ESWT+MFR is more effective than myofascial release techniques for pain, movement, and function in patients with myofascial pain syndrome and would be clinically useful for physical therapists treating myofascial pain syndrome.
Purpose : This study attempts to assist stroke patients lead independent daily life movements by providing basic data for stroke patients' successful rehabilitation program and understanding the relationship between health beliefs of stroke patients and their guardians, and patients' rehabilitation performance level and daily life movement fulfillment ability. Methods : 23 stroke patients receiving treatments at rehabilitation specializing hospital after getting diagnosed with a stroke, along with 23 guardians were selected as research subjects, and health belief was measured by modifying supplementing Byun Young-Hee(2002)'s health belief measurement tool for leg movement disorder patients. Research findings revealed the following relationship between health beliefs of stroke patients and their guardians, and patients' rehabilitation performance and daily life movement fulfillment ability. Results : The patients group's initial MBI score was $33.13{\pm}3.46$, and measurement after four weeks was $38.43{\pm}3.47$. As health beliefs got stronger, MBI score increased significantly(p<.05). Correlation analyses of factors that affect rehabilitation attendance rate showed that perceived susceptibility, seriousness and usefulness were statistically significant, and perceived disability was not statistically significant(p<.05). Guardians' health belief index(susceptibility, seriousness, usefulness, disability) had no correlation with rehabilitation attendance rate. Conclusion : In order to increase daily life movement fulfillment ability of patients who are being treated with stroke, health beliefs must be raised to increase changes in daily life movement fulfillment ability. Therefore, it is believed that managing programs that can increase health beliefs of stroke patients can allow patients obtain positive health beliefs, further increase rehabilitation performance rate of stroke patients as well as independent daily life ability.
Background: Despite muscle latency times and patterns were used as broad examination tools to diagnose disease and recovery, previous studies have not compared the dominant arm to the non-dominant arm in muscle latency time and muscle recruitment patterns during reaching and reach-to-grasp movements. Objects: The present study aimed to investigate dominant and non-dominant hand differences in muscle latency time and recruitment pattern during reaching and reach-to-grasp movements. In addition, by manipulating the speed of movement, we examined the effect of movement speed on neuromuscular control of both right and left hands. Methods: A total of 28 right-handed (measured by Edinburgh Handedness Inventory) healthy subjects were recruited. We recorded surface electromyography muscle latency time and muscle recruitment patterns of four upper extremity muscles (i.e., anterior deltoid, triceps brachii, flexor digitorum superficialis, and extensor digitorum) from each left and right arm. Mixed-effect linear regression was used to detect differences between hands, reaching and reach-to-grasp, and the fast and preferred speed conditions. Results: There were no significant differences in muscle latency time between dominant and non-dominant hands or reaching and reach-to-grasp tasks (p>.05). However, there was a significantly longer muscle latency time in the preferred speed condition than the fast speed condition on both reaching and reach-to-grasp tasks (p<.05). Conclusion: These findings showed similar muscle latency time and muscle activation patterns with respect to movement speeds and tasks. Our findings hope to provide normative muscle physiology data for both right and left hands, thus aiding the understanding of the abnormal movements from patients and to develop appropriate rehabilitation strategies specific to dominant and non-dominant hands.
Lumbar segmental instability is considered to represent a significant sub-group within the chronic low back pain population. This condition has a unique clinical presentation that displays its symptoms and movement dysfunction within the neutral zone of the motion segment. The loosening of the motion segment secondary to injury and associated dysfunction of the local muscle system renders it biomechanically vulnerable in the neutral zone. There in evidence of muscle dysfunction related to the control of the movement system. There is a clear link between reduced proprioceptive input, altered slow motor unit recruitment and the development of chronic pain states. Dysfunction in the global and local muscle systems in presented to support the development of a system of classification of muscle function and development of dysfunction related to musculoskeletal pain. The global muscles control range of movement and alignment, and evidence of dysfunction is presented in terms of imbalance in recruitment and length between the global stability muscles and the global mobility muscles. The local stability muscles demonstrate evidence of failure of aeequate segmental control in terms of allowing excessive uncontrolled translation or specific loss of cross-sectional area at the site of pathology Motor recruitment deficits present as altered timing and patterns of recruitment. The evidence of local and global dysfunction allows the development of an integrated model of movement dysfunction. The clinical diagnosis of this chronic low back pain condition is based on the report of pain and the observation of movement dysfunction within the neutral zone and the associated finding of excessive intervertebral motion at the symptomatic level. Four different clinical patterns are described based on the directional nature of the injury and the manifestation of the patient's symptoms and motor dysfunction. A specific stabilizing exercise intervention based on a motor learning model in proposed and evidence for the efficacy of the approach provided.
