Moon, Gon-Sung ; Kim, Tack-Hoon ;
Physical Therapy Korea, volume 18, issue 2, 2011, Pages 1~8
The purpose of this study was to investigate the effect of high heeled shoes with the total contact insert (TCI) on the frontal plane of the joints for the lower extremity during the gait. Ten healthy females voluntarily participated in this study and the height of the high heeled shoes was 7 cm. A three-dimensional motion analysis system (VICON) and force plates were used to analyze the movements of the joints for the lower extremities. The results were as follows: There were no significant differences for the angle value on the event of the gait cycle in the maximum eversion and inversion of the ankle joint, the varus and valgus of the knee joint, and the adduction and abduction of the hip joint (p>.05). But, there was a significant difference or the range of motion in the ankle joint (p<.05). The value of ankle and knee moment with a TCI was less than the value for no TCI. And there were significant differences for the moment value of the maximum inversion and eversion on the ankle joint and for the maximum varus and valgus on the knee joint (p<.05). Therefore, a TCI would be effective in stabilizing the joints of the lower extremities and increasing the balance of a body to reduce the injure from a fall during the gait.

The objective of this research was to examine the effects of lumber stabilization exercise and a general physiotherapy program for caregivers with chronic low back pain. Sixteen people participated in this study and were randomly assigned to two groups for either lumbar stabilization exercise or for general physiotherapy, respectively. The experiment was performed for eight weeks. To examine the general as well as the medical characteristics of the participants, the following measurements were used: Visual Analogue Scale (VAS); Oswestry Disability Index (ODI); Back Performance Scale (BPS); Roland - Morris Disability Questionnaire (RMDQ); and Beck Depression Index (BDI). To compare the general and medical characteristics of the participants in the two groups, an independent t test were used. During the experiment, a paired t test was conducted to determine whether there was a significant difference in the values of VAS, ODI, BPS, RMDQ, and BDI before and after the experiment. To examine the difference in the VAS, ODI, BPS, RMDQ, and BDI values in the two groups, ANCOVA was used with pre test values as a covariate. According to the test results, in the lumbar stabilization exercise group, the VAS, ODI, BPS, RMDQ, and BDI values showed a statistically significant difference before and after the test (p<.05). In comparison, in the general physiotherapy program group, only the ODI and BPS values showed a statistically significant level of improvement. Regarding the degree of improvement, participants in the lumbar stabilization exercise group showed statistically significant progress compared to those in the general physiotherapy group. In summary, lumbar stabilization exercise is regarded as more effective than general physiotherapy for treating caregivers with chronic low back pain. In future studies, it will be useful to expand the research and to examine the long term effects of lumbar stabilization exercise on workers.
Effect of Task-Oriented Approach on Weight-Bearing Distribution and Muscular Activities of the Paretic Leg During Sit-to-Stand Movement in Chronic Stroke Patients
Kim, Won-Ho ;
Physical Therapy Korea, volume 18, issue 2, 2011, Pages 18~26
The purpose of this study was to investigate the effects of a task-oriented approach on weight-bearing distribution and muscular activities of the paretic leg during sit-to-stand movement in 18 chronic stroke patients. Both groups were received neurodevelopmental treatment for 30 min/day and then the experimental group (
=9) followed additional a task-oriented approach (sit-to stand training with controlled environment) and the control group (
=9) followed a passive range of motion exercise for 15 min/day, five days/week, for four weeks. Weight-bearing distribution and muscular activities of the paretic leg during sit-to-stand movement were measured before and after four weeks of training. There was significantly improved weight-bearing distribution of the paretic leg during sit-to-stand movement in the experimental group compared with that of the control group after four weeks of training (p<.05). But electromyographic activities of the quadriceps and the tibialis anterior of the paretic leg were not significantly different (p>.05). Thus, it is necessary to apply a task-oriented approach to improve the weight-bearing distribution of the paretic leg during sit-to-stand movement in chronic stroke patients.

The aim of this study was to determine the effect of action-observation training on arm function in people with stroke. Fourteen chronic stroke patients participated in action-observation training. Initially, they were asked to watch video that illustrated arm actions used in daily activities; this was followed by repetitive practice of the observed actions for 3 times a week for 3 weeks. Each training session lasted 30 min. All subject participated 12 training session on 9 consecutive training days. For the evaluation of the clinical status of standard functional scales, Wolf motor function test was carried out at before and after the training and at 2 weeks after the training. Friedman test and Wilcoxon signed rank test was used to analyze the results of the clinical test. There was a significant improvement in the upper arm functions after the 3-week action-observation training, as compared to that before training. The improvement was sustained even at two weeks after the training. This result suggest that action observation training has a positive additional impact on recovery of stroke-induced motor dysfunctions through the action observation-action execution matching system, which includes in the mirror neuron system.

Three hundred and fourteen low back pain patients completed the Korean version of the Oswestry Disability Questionnaire (KODQ) and the Rasch analysis was then applied to identify the inappropriate items and to determine ODQ item difficulties according to a subject's characteristics. For women and youths, the 'sex life' item showed misfit statistics, whereas for older subjects it was the 'pain intensity' and 'standing' items. Also, in the acute low back group the 'pain intensity', 'standing' and 'sex life' items showed misfit statistics. For all subjects, the most difficult item was 'pain intensity', whereas the easiest item was 'walking'. But for the older and acute groups 'lifting' was the most difficult item and for those who have a visual analogue scale score of 3 or less 'sitting' was the most difficult item. These results show that differential item functioning is present in several items according to sex, age, acute and chronic pain, and VAS score. This study may be useful for adjusting the KODQ item difficulties for low back pain patients with different characteristics.

Balance is a complex motor skill that depends on interactions between multiple sensorimotor processes and environmental and functional contexts. Many rehabilitation specialists believe that balance assessment under multitask conditions may be a more sensitive indicator of balance problems and falls than balance assessment in a single-task context. Functional Gait Assessment has many tasks that allow for testing under multitask conditions. The purpose of this study was to determine the concurrent validity between the Functional Gait Assessment (FGA), Berg Balance Scale (BBS), and Timed "Up & Go" Test (TUG) in patients with stroke. One hundred and five participants with at least 3 months post stroke and able to walk at least 6 m with or without a mono cane, participated in this study. Concurrent validity between the FGA, BBS, and TUG was assessed using Spearman rank order correlation. The FGA correlated with the BBS (r=.80, p<.01) and TUG (r=-.77, p<.01). The good and moderate correlation between the FGA, BBS, and TUG establishes the concurrent validity of the FGA in patients with stroke. These measures provide clinicians with valuable information about patients' functional balance capabilities.

The purpose of this study was to examine the relationship of the Stroke Rehabilitation Assessment of Movement (STREAM), the Berg Balance Scale (BBS), and the Modified Barthel Index (MBI) in the acute stroke care setting. Twenty patients with their first stroke were evaluated using STREAM, BBS, and MBI initially and at 4 weeks. The data was analyzed using the independent t-test, paired t-test, and the Pearson product moment correlation analysis. The scores on the STREAM were strongly associated with the scores on both the BBS and MBI (with Pearson correlation coefficients ranging from .88 to .95), and there was significant improvement between the initial scores and those obtained four weeks later for STREAM, BBS, and MBI (p=.001, p=.001, p<.001). The results suggest that STREAM may be able to reflect functional recovery and to assess voluntary movement in patients who have suffered an acute stroke.

Foot posture is important in the development of the musculoskeletal structure in the lower limbs because it can change the mechanical alignment. Although foot orthotics are widely used for the correction of malalignments in the lower extremities, the biomechanical effects of wedges have not yet been cleared. The aim of this study was to investigate whether medial wedges affect the electromyographic (EMG) activity of the knee and hip joints in healthy adults that are performing one leg standing. Seventeen healthy volunteers performed the one leg standing under two foot conditions: A level surface, and a
medial wedge. The subjects' EMG data for the gluteus maximus (Gmax), gluteus medius (Gmed), tensor fasciae latae (TFL), biceps femoris (BF), vastus lateralis (VL), and vastus medialis oblique (VMO) were recorded, along with the surface EMG, and all were analyzed. The EMG activity of the Gmed and TFL had significantly decreased under the medial wedge condition during one leg standing. Further study is needed in order to investigate whether medial wedges influence the EMG activity and kinematic data of the knee and hip joints as well as the ankle joints in adults with flexible flatfoot, while they are performing one leg standing.

The purpose of this study was to investigate the effects of virtual reality (VR) therapy with compensation inhibition and feedback (CIF) on upper extremity function in chronic stroke patients. Seven chronic stroke patients participated in this study, which was a randomized controlled trial with a crossover design. Self upper extremity exercise, conservative VR therapy, and VR therapy with CIF were performed for one hour per session, 5 times per week, over a 3 week period. The main outcome measures involved range of motion (ROM) including shoulder, elbow, and wrist joints, a Manual Function Test (MFT), and a Motor Activity Log (MAL). Data were calculated as posttest and pretest changes in every session and were analyzed using Friedman and Wilcoxon signed-rank tests at p<.05. The results were as follows: 1) Statistically significant increase in ROM measurements of shoulder and elbow joints were seen with VR therapy with CIF compared to VR therapy and self upper extremity exercise (p<.05), whereas no significant increasing was noted for the wrist joint (p>.05). 2) Statistically significant increase in the MFT was seen with VR therapy with CIF compared with VR therapy and self upper extremity exercise (p<.05). 3) VR therapy with CIF also resulted in statistically significant increase in both activity of use (AOU) (p<.05) and quality of movement (QOM) (p<.05) on the MAL test when compared with VR therapy and self upper extremity exercise, respectively. In conclusion, VR therapy with CIF was more effective than conservative VR therapy and self upper extremity exercise in improving the upper extremity function in hemiplegic patients with chronic stroke.

The aim of this study was to determine the immediate effects of single treatment of strain-counter strain (SCS) on pressure pain threshold (PPT) and muscle activity during scapular plane abduction with 3% body weight load. Fifteen asymptomatic male adults with upper trapezius latent trigger point (LTrP) (PPT<2.9
) participated in this study. Pressure algometer was used to measure PPT and surface electromyography was used to record upper, middle arid lower trapezius, serratus anterior, infraspinatus and middle deltoid muscle activity and relative ratio during scapular plane abduction between pre- and post-intervention. There was a significant increase in upper trapezius PPT after a 90-second SCS (p<.05). The activity of the upper trapezius and middle deltoid was significantly decreased (p=.014, p=.001), coupled with a decreased muscle activity ratio between the upper and lower trapezius (p<.05). These results indicate that the SCS may effectively deactivate upper trapezius activity, thereby alleviating muscle balance and reducing pain sensitivity.
