Purpose : Selective functional movement assessment(SFMA) is a movement-based assessment tool designed for clinicians to diagnose and treat pain and functional physical problems. This concept is used for assistance in occupations related to movement, including clinical medical personnel, such as physical therapists, physical education instructors, and athlete coaches. Although this concept is widely used by clinicians, research and scientific proofs are relatively insufficient. This study aimed to review the literature on the understanding, reliability and effectiveness of SFMA, and to consider its role in the future of rehabilitation. Methods : In this review, a total of nine articles were selected according to the eligibility criteria of three major thesis topics. The main topics covered in the literature are reliability and effectiveness of clinical use of SFMA. To gather research articles, we searched official term 'Selective Functional Movement Assessment'. Among the searched 60 studies, nine were mentioned in this study that contained overlapping information and matched our desired topic. We reviewed four reliability analyses, four case reports, and one experimental study. Results : Reliability has an intermediate degree between high raters and within raters. The validity of the SFMA system is influenced by a combination of experience and logic; hence, further improvement is needed. Therefore, if the intervention was effective based on the diagnosis result, then biomechanical evidence is necessary to further support the claim. Conclusion : In future research, to use SFMA as a diagnostic tool with high accuracy, it is necessary to improve the reliability of the main problem through breakout, support for guidelines and validity and efficiency.

Objective: The purpose of this study was to examine the effects of balance training with Functional Electrical Stimulation (FES) on balance and gait in patients with chronic stroke. Design: A cross over design Methods: Nine patients with stroke were recruited into this study. They were measuring their balance ability and gait ability. The intervention "A" included 4 weeks of balance training with Functional Electrical Stimulation (FES) for 40 m/d, 3 d/wk. Intervention "B" included 4 weeks of balance training with placebo Functional Electrical Stimulation (FES) for 40 m/d, 3 d/wk. Of the 9 patients who completed the study, 5 were randomly assigned to" group A-B", and 4 to group B-A. The crossover occurred after 4 weeks. Results: Following are the specific results of balance training with Functional Electrical Stimulation (FES) on patients with chronic stroke. First, patients who received treatment A showed improvement compared with patients who received treatment B in static balance. There were significant decreases in anterioposterior, mediolateral postural sway extension and velocity moment (p<0.05) with their eyes opened and closed conditions. Second, they had significantly improved in dynamic balance (p<0.05). Lastly, there were also improvement in their gait velocity and cadence (p<0.05). Conclusions: These findings suggest that, the Functional Electrical Stimulation (FES) combined with balance training more effectively improves the balance and gait ability, I'm convinced that it could be actively used in clinics added to the conventional physical therapy in the future.

The objective of this study was to discover the effects of the short-term home visiting physical therapy program involving patients with some chronic brain disorders at Gimhae City, Kyongnam. Recovery of activities of daily living (ADL) is a very important factor of rehabilitative procedures, and Functional Independence Measure (FIM) is a useful standard of evaluation for it. The FIM is widely used in brain disorder research because it measures real functional activities of daily living. We applied the physical therapy exercise program twice per week (10~15 times repeatedly); a warm-up and cool down exercise performed every ten minutes by active & active-assistive ROM and stretching exercises. Main exercises were composed of getting up & laying down in bed, standing training, walking exercise in the room, and window or wall sliding exercise using affected upper limbs for a total duration of 30 minutes. We collected the data from 20 patients with chronic brain disorders at his/her home and analyzed by means of SPSS/PC+ program (Ver. 10.0). After the six week long physical therapy exercise program, the average was $56.10{\pm}22.59$ point compared with initial $50.55{\pm}19.12$ point by FIM, improved functional ADL ability about 5.55 point, and these changed scores were statistically significant (p=.000). We also studied another factor regarding patient's satisfaction. The majority of subjects (10 people) rated the program with the maximum score of ten points (50.0%), and three people rated it a seven point program (15.0%), the other two subjects gave a rating of nine and eight points (10.0%). Because the program was effective at improving the physical ADL ability and satisfaction of each subject, we suggest continual development and implementation of a home visiting physical therapy program. Further study should involve a longer period of observation with a larger population that is involved in an individually designed home physical therapy program.

Purpose: Changes of degenerative disc have been analyzed or with the Magnetic Resonance Imaging (MRI) to assign appropriate meaning, and the relationship between the degenerative changes of the discs and its living function has been evaluated through the living function evaluation scores collected by functional rating index. Methods: in April, 2006, a physical examination was conducted for physical laborers to be employed as on-site laborer in a steel industrial complex located at a region. A month later, these 20 laborers who participated in lumbar vertebra MRI tests have been investigated for one-to-one mobile phone functional rating index test. Excluding 3 of 14 respondents whom scored 0 in functional rating index, the rest of respondents' degenerative disc grade changes shown in MRI and its relationship to living functional rating index have been performed. Results: The Dabbs method of measuring disc height resulted to show significant increase as the disc height changes from L1-2 level to L5-S1 level (p<0.01). However, there was no statistical significance with a relationship between disc height and functional rating index, and disc height average. The Magnetic Resonance Imaging analysis regard on the degree of disc degeneration and its relationship to living functional rating proved to have significant relationship (p<0.05). Conclusion: The degenerative changes monitored by Magnetic Resonance Imaging show significant relationship (p<0.05) to living function. However, this relationship could vary depend upon the characteristics of study population. So, it suggested that the future studies should be performed by considering population's age and job career.

The purpose of this study was to analyze the effects of three different pelvic tilts on a sit-to-stand (STS) and to suggest a new assessment approach based on biomechanical analysis. The three difrent pelvic tilts were: (1) comfortable pelvic tilt sit-to-stand (CPT STS), (2) posterior pelvic tilt sit-to-stand (PPT STS) and (3) anterior pelvic tilt sit-to-stand (APT STS). To determine the onset time of muscle contraction surface electrodes were applied to the rectus femoris muscle (RF), vastus lateralis muscle (VL), biceps femoris muscle (BF), tibialis anterior muscle (TA), gastrocnemius muscle (GCM), and soleus muscle (SOL). The ICC was used for functional linkage analysis. The findings of this study were as follows. First, significant differences were found in kinematic variables and in muscle activation pattern among the three activities. Second, the results of functional integrated analysis revealed that recruited muscle activation patterns changed when the thigh-off was viewed as a reference point. Third, there were independent functional units between the thigh-off and the VL and between the thigh-off and the RF in the functional linkage analysis. The VL and RF acted as prime mover muscles, and more postural adjustment muscle recruitment was required as the demand of postural muscle control increased (PPT STS, APT STS, and CPT STS in order). In conclusion, the findings of this study suggest the following evaluative and therapeutic approach for STS activity. APT STS can be introduced for movement efficiency and functional advantage when abnormal STS is treated. However, excessive APT would change the muscle activation patterns of BF and SOL and require additional postural muscle control to cause abnormal control patterns.

Background: Patients after rotator cuff (RC) surgery experienced pain, weakness and limited of motion of the shoulder. Physical therapists have used heat therapy, electrotherapy, range of motion (ROM) exercise and other methods to treat patients after RC surgery. In addition, functional taping is also used to support joint movement and to increase shoulder joint stability. Objects: The purpose of this study was to determine the initial effects of functional taping using non-elastic tape on pain, strength and ROM of the shoulder following RC surgery. Methods: Forty-eight patients with who underwent RC surgery volunteered for this study. The subjects were randomly divided into an experimental group (EG, $n_1=25$) and a control group (CG, $n_2=23$). First, non-allergic tape was applied to the shoulder to prevent skin irritation. The EG applied functional taping using non-elastic tape and the CG applied sham taping using elastic tape. Assessment tools included the shoulder pain and disability index for functional activity score, visual analog scale for level of pain, shoulder muscle strength, hand grip strength and ROM testing. Results: Pain score in the both group significantly decreased (p<.05), and change in pain score of in the EG increased significantly than in the CG (p<.05). Shoulder strength and ROM in the both group significantly increased (p<.05). Especially external rotation and extension of the shoulder ROM in the EG increased significantly more than in the CG (p<.05), but the rate of change in the two groups showed no significant difference. Conclusion: These results suggest that functional taping using non-elastic tape was initially effective in decreasing pain score level in patients with RC surgery.

PURPOSE: Examine the effects of auditory feedback and functional electrical stimulation on balance, walking ability, and lower extremity function of subacute stroke patients. METHODS: Twenty-seven subjects diagnosed with subacute stroke within six months were randomly divided into three groups: test group 1, which performed walking exercises with auditory feedback and functional electrical stimulation; test group 2, which performed walking exercises only with functional electrical stimulation; control group applied only functional electrical stimulation, with nine subjects each. RESULTS: There were significant pre- to post-intervention differences in BBS in the gait training group with auditory feedback and functional electrical stimulation treatment, and significant pre- to post-intervention differences in BBS, sit-to-stand time, and average step speed in the gait training group with functional electrical stimulation, but no statistically significant differences in between-group comparisons. CONCLUSION: Gait training with auditory feedback and functional electrical stimulation can improve the balance and gait performance in stroke patients. Therefore, in the future, gait training with auditory feedback and functional electrical stimulation therapy may be suggested as a gait rehabilitation training tool for stroke patients.

The objectives of this study were to investigate the relationship between fear-avoidance beliefs and functional status in individuals suffering from low back pain, and to identify factors that influence on fear-avoidance beliefs, functional status and pain. A cross-sectional study included 214 individuals with low back pain. Each of subjects completed a fear-avoidance beliefs questionnaire (FABQ) which divided into two subscales, FABQ for physical activity (FABQ-PA) and FABQ for work(FABQ-W), Oswestry disability index (ODI) and numeric pain rating scale (NPRS). Individuals with radiating pain were significantly higher in FABQ-PA, FABQ-total, and ODI scores than with no radiation pain (p<.05). Individuals who had received surgery were significantly higher in FABQ-PA, FABQ-total, ODI and NPRS scores when compared with individuals who had not received it (p<.05). And individuals with taking medication were significantly higher in all variables (FABQ-PA, FABQ-W, FABQ-total ODI and NPRS) than individuals not taking medication (p<.05). In correlation analysis. age appeared to be significantly correlated with FABQ-PA, FABQ-total and ODI scores (p<.05), and all variables was significantly correlated with each other (p<.01). These findings indicate that individuals suffering from low back pain have psychosocial problems such as fear-avoidance beliefs as well as functional status and pain. Fear-avoidance beliefs may contribute to aggravate physical symptoms, and therefore it should be carefully considered for the management of individuals with low back pain.
