Objective: The present study was to investigate the discrimination capacity of the Performance Oriented Mobility Assessment-Gait Scale (POMA-GS), for predicting falls in stroke survivors. Design: Retrospective cohort study. Methods: Data including the characteristics and number of falls of 52 chronic stroke patients from a rehabilitation center were collected. The number of falls each subject had experienced in the previous year were investigated through interviews. The subjects were divided into two groups depending on the number of falls: if falls occurred twice or more on the basis of the time of study after stroke, they were defined as the falls group and if there was no fall experience or one fall, they were defined as the non-falls group. The subjects were examined with the POMA-GS, and physical functions were examined using by the One Leg Stand Test (OLST), Sit to Stand Test (SST), 10-m Walk Test, Lower Extremity in Fugl-Meyer assessment (FM-LE), and Trunk Impairment Scale (TIS). The validity of POMA-GS for falls prediction was analyzed. Results: In the POMA-GS, which predicts falls in stroke survivors, the cut-off value was 8.5 (sensitivity 72%; specificity 65%) and the area under the curve was 0.75 (95% confidence interval: 0.60-0.90, p<0.007). There was a significant difference in the OLST, SST, FM-LE, and TIS between the subjects with POMA-GS >8.5 and the subjects with POMA-GS
. Conclusions: The POMA-GS could be a useful tool in predicting falls in stroke survivors, as its discrimination capacity and predictive validity is proven satisfactory.

Objective: This study was to investigate the effects of Task-oriented training for Gross Motor Function Measure (GMFM), gait and balance function in cerebral palsy. Design: Randomized controlled trials. Methods: Twenty four subjects were recruited by means of a convenience sampling from Kangseo-Gu G rehabilitation center. Subjects were 24 inpatients and were randomly divided into a task-oriented training group and a conventional group. Twelve patients were experimental group who executed the task-oriented training (5 times/wk) for 4 weeks. The task-oriented program mainly focused on the capabilities of independent walking, with the angle of inclination set at 0 degrees and walking at a self-selected comfortable speed. In addition, balance training included the one-legged standing with weight-shifting and task-oriented training. Twelve patients were control group who executed only general conventional therapy (5 times/wk) for 4 weeks. All subjects were evaluated about the motor function, gait and balance function. Subjects have conducted the measured variables, GMFM, GAITRite, PDM Multifunction Force Measuring Plate after treatment. Results: There was statistically significant increase of Gross Motor Function Measure scores of the experimental group and control group after 4 weeks (p<.05). There was statistically significant increase of gait and balance function of the experimental group after 4 weeks of task-oriented training (p<.05). The experimental group showed a significantly improvement in GMFM, gait, and balance compared to the control group (p<0.05). Conclusions: This study proved that task-oriented training after stroke can improve Gross Motor Function Measure, gait and balance. Thus this study can suggest that task-oriented training for gross motor function, gait and balance be effective on the cerebral palsy.

Objective: The purpose of this study was to see the changes in muscle activity of the upper limb in persons using a smartphone. Design: Cross-sectional study. Methods: An experiment was conducted to target 15 right-handed university students. Experiments were carried out for students using cell phones for more than a year. In this study, experiments were carried out with one-handed and both handed operation of smartphone use in a sitting position, the same parameters with smartphone use in a standing position. The experiments were carried out by having the subjects write a text message in Korean on the smartphone for 3 minutes repeated 3 times with a rest period of 10 seconds given between each 3 minute period. Electromyography (EMG) was used to record the muscle activity of the upper trapezius (UT), extensor carpi radialis (ECR), and abductor pollicis (AP) during phone operation. Results: The muscle activity of the AP and ECR were significantly higher during single handed compared to double handed in both sitting and standing position (p<0.05). The muscle activity of the ECR was significantly higher in standing position compared to sitting position with double handed use of the smartphone (p<0.05). UT muscle activity of the right has been activated more than twice compared to the left UT in a sitting position (p<0.05). And UT muscle activity on the right has been activated more than five times compared to the left in a standing position (p<0.05). Conclusions: Using smartphone with double hand is useful for the prevention of musculoskeletal disorders.

DOI : 10.14474/ptrs.2016.5.1.29
Objective: This study compared the muscle activities of the erector spinae (ES), the external oblique (EO), and the rectus abdominis (RA) on three different surfaces. The purpose of this study was to determine which surface induces the highest muscle activity during the plank exercises. The information from this study can be used to recommend plank exercises to athletes and patients with weak core muscles. Design: Cross-sectional study. Methods: The subjects include 20 adult males attending S University in Seoul. Participants completed each plank exercise on three different surfaces. To measure muscle activities, researchers used the values from electromyography. The measurement excluded the initial two and final two seconds and collected information on the RA, EO, and ES in each posture of each subject. Results: The left external oblique showed significant differences between the plank position on stable ground (ST) and the plank position using a suspension device (SL) (p<0.05) and between the plank position on the unstable ground (US) and SL (p<0.05). The right rectus abdominis and left rectus abdominis displayed statistically significant differences between the ST and the US (p<0.05) and between the ST and the SL (p<0.05). The right erector spinae had a statistically significant difference between ST and US (p<0.05). Conclusions: The plank exercise strengthens the core muscles effectively, and muscle activity is related to the posture of the exercise and the location of the muscle. These results suggest that plank exercises improve muscle activities. Additionally, plank exercises can be applied to general medical care.

Objective: Hip abductors play a role in providing stability and movement to the lower limbs. The purpose of this study was to examine the effects of hip abductor fatigue on static balance and gait in the general population. Design: One group pre-test post-test design. Methods: Thirteen university students in their twenties volunteered for the study and had underwent a functional assessment. To induce fatigue, the subjects were instructed to raise their dominant lower extremity up against a load of 50% of 1 repetition maximum while producing hip abduction in a side-lying position. Subjects were instructed to maintain an abduction speed of 30 repetitions per minute to induce fatigue. Muscle fatigue was considered to be established when subjects were unable to perform hip abduction three consecutive times along with the metronome. A post-test of balance and gait was performed immediately in order to prevent fatigue recovery. The center of pressure (COP) distance area was measured using the Zebris FDM-S Multifunction Force measuring plate. Gait performance was analyzed using the GAITRite. Results: The COP distance was increased after fatigue was induced. There was a significant increase in the standard deviation of the medio-lateral and antero-posteror distance (p<0.05). Although there was no significant difference in gait parameters, there was a significant decrease in single support time after fatigue was induced (p<0.05). Conclusions: There was an increase in static balance instability and a significant decrease in single support time during gait due to hip abductor muscle fatigue.

Objective: The purpose of this study was to examine the effect on multifidus and external oblique abdominis muscle activation during hip contraction of three types (concentric, isometric, eccentric) in standing position. Design: Cross-sectional study. Methods: Twenty healthy adult men volunteered to participate in this study. Muscle activation was recorded from gluteus maximus, both multifidus, and both external oblique abdominis by surface electromyography (EMG) while holding position in the type of gluteus maximus contraction. EMG values were normalized by maximum muscle contractions (% maximum voluntary isometric contraction). All subjects performed hip extension with three contraction methods. The type of gluteus maximus contraction using Thera-band was composed of concentric contraction (type 1), isometric contraction (type 2), and eccentric contraction (type 3). To measure muscle activation on the gluteus maximus contraction type, each position were maintained for 5 seconds with data collection taken place during middle three seconds. Muscle activation was measured in each position three times. Results: For the results of this study, there was no significant difference within three contraction patterns of the gluteus maximus (concentric, isometric, and eccentric) each both multifidus, both external oblique abdominis, and gluteus maximus. And there was no significant difference among both multifidus, both external oblique abdominis, and gluteus maximus each hip extension contraction type. Conclusions: These findings suggest that specific contraction types of the gluteus maximus does not lead to a more effective activation of the multifidus, external oblique abdominis, and gluteus maximus.

Objective: This study surveyed the perceptions of physical therapists on muscle re-education through visual feedback obtained from rehabilitative ultrasound imaging (RUSI). Design: Survey. Methods: For this study, 500 physical therapists who participated in a refresher training held by the Seoul City Association in March 2015 were selected for a questionnaire-based survey. Subjects were randomly selected targets physiotherapists who participated in a refresher training.The questionnaire had 21 items in total. Questions 1 to 15 could be answered by everyone. However, questions 16 to 21 could be answered only by people who used RUSI. Results: The majority of respondents were aged 20 to 30 years. Respondents in their twenties, thirties, forties, and fifties accounted for 32.4%, 40.2%, 21.9%, and 5.6%respectively. Therapists with careers spanning one to 5 years accounted for 27.8%, while those with careers spanning 5 to 10 years and 10 to 15 years accounted for 34.6% and 17.0%, respectively. Those with careers over 20 years accounted for 9.2%. The types of work have not been various including work related to the nervous system (49.0%), the musculoskeletal system (41.5%), sports (0.7%), juvenile physical therapy (4.2%), and others (4.6%). Conclusions: In this study, we examined the perceptions of physical therapists on rehabilitation ultrasound imaging used in muscle re-education. We also examined how to use this technique. Many therapists who participated in the refresher training were found to be unaware of RUSI. In the future, further investigations on RUSI for muscle re-education are required through refresher training or training lectures at the national level.
