Purpose: The objective of this case report is to examine the impact of physical therapy using the proprioceptive neuromuscular facilitation (PNF) concept for a patient with shoulder impingement syndrome. Methods: The patient is a 35-year-old female who has felt pain in the right shoulder for one month. The physical examination evaluated sensory integration, pain, joint integration and mobility, posture, reflex integration, range of motion, muscular strength, analysis of movement, and shoulder function. Comprehensive physical therapy was given to the patient, including stretching, mobilization, strengthening, posture correction, coordination improvement, daily activities, and sports exercises. The therapy was given 5 times a week for the first 5 weeks, then 3 times a week for the next 5 weeks. In all, the intervention lasted for 10 weeks. Results: The patient's senses, posture, and muscular strength all improved to a normal level. The degree of pain fell from 3/10 to 0/10 for activities taking place below shoulder height, and from 8/10 to 1/10 for activities above the head. Additionally, joint integration, motility, range of motion, and movements also improved. The disabilities of the arm, shoulder and hand (DASH) for functional evaluation improved from 27.5 to 10.3. Conclusion: Physical therapy using the PNF concept is effective in improving the body structure, function, activity, and participation of patients with motor disorders of the shoulder impingement syndrome.
Background: The purpose of this study was to investigate the effect of open and close kinetic chain exercise on the muscle activity of pectoralis major and triceps. Method: Twenty healthy male college students were assessed three times over two weeks. The participants were randomly assigned to OKCE(Open Kinetic Chain Exercise) and CKCE(Close Kinetic Chain Exercise). On the first day, the 7th day and the last day, The MP(mean power) and PT(peak torque) of the PM(pectoralis major) and TR(triceps) during the exercise were measured with an electromyography device and the study was compared. Result: In the present study, it was found that Statistical analysis of the measured values at the end of experimental period revealed statistically significant differences in the MP and PT values of TR and PM. Conclusion: These findings suggest that CKCE and OKCE may be an effective physical therapy intervention for strengthening muscular activity in patients with low activity in the upper limb, including normal subjects, although it is not suitable for effective exercise by selecting either CKCE or OKCE.
The purpose of this study were to examine the effect of two different pelvic alignments and the back belt on electromyographic(EMG) activity of the erector spinae during lifting. The results were as follows: 1) EMG activity of erector spinae was greater when the pelvis was tilted anteriorly than when the pelvis was tilted posteriorly during lifting. 2) EMG activity of erector spinae was greater when the back belt than when without the back belt during lifting. These results suggest that the greater EMG activity of erector spinae with an anterior pelvic tilt position and with back belt during lifting may ensure optimal muscular support for the spine while handling loads.
Purpose: The purpose of this study is to identify the effect of 24-week sensory integration activity training on fitness of children with intellectual disability. Research design, data, and methodology: The subjects were 10 children with intellectual disability, 60 min training of sensory integration activity for 24 weeks. Obesity, cardiovascular endurance, muscular strength and muscle endurance were measured pre and post training. Frist, characteristics of subjects were measured with age, height, weight, IQ and SQ. Second, the subjects then performed sensory integration activity training for 24 weeks. Last, weight, strength, endurance, cardiovascular endurance and flexibility were measured. Data were calculated for average and standard deviation by SPSS 25.0 statistic program, and dependent sample t-test was processed to analyze the change between pre and post training. All statistical significance level was set to 0.5. Results: The result was shown that weight, strength and endurance changes between pre and post were significant. However, cardiovascular endurance, flexibility changes between pre and post were not significant. Conclusions: The lack of training frequency of 60 minute per week were acknowledged per week from this result. In future research, increased intensity and frequency are need for an in-depth and meaningful study and the measured data can be used basic information for the study.
Background: This study examined the relationship between interhandle distances and upper limb exertion during simply pushing and pulling of a cart with four swivel wheels, defined by a roll box pallet (RBP) in a Japanese industrial standard. Methods: Six healthy young male participants were asked to push and pull an RBP at a distance of 5.2 m under six conditions corresponding to different interhandle distances (40 cm, 60 cm, and 80 cm) and weights (130 kg and 250 kg). The upper limb exertion was studied by shoulder abduction and flexion, and elbow flexion, as well as surface electromyogram (EMG) in shoulder extensor, and elbow flexor and extensor. Participants were required to provide subjective evaluations on operability after each trial. Results: Subjective operability indicated that a narrower interhandle distance had a better operability for pushing. Interhandle distance was also related to upper limb exertion especially for pushing. A narrow interhandle distance caused smaller shoulder adduction but larger elbow flexion. The normalized EMG data revealed that muscular activity became smaller with a narrow interhandle distance in shoulder extensor. During the pulling task, elbow flexion was smaller at a narrow interhandle distance, although subjective operability and normalized EMG were not significantly varied. Conclusion: A wider interhandle distance, such as 80 cm, was not suitable in the forwardbackward movement of the RBP. Therefore, this study concluded that an interhandle distance of 40 cm would be suitable for pushing and pulling an RBP to protect the workers' hands against the risk of injury by installing inner handles.

The purpose of this study is to investigate and reveal the effects that the complex exercise training consisting of aerobic exercise and strength training(sit up, push up) that everyone can easily practice regardless of a time and a place in order to manage practically the physical strength of the aged affects the difference on their body composition and the change of physical fitness level. Looking into the change of body composition of an experimental group, the weight of 2.5kg was reduced after applying complex training for 12 weeks and the body fat mass of 2.65kg was reduced. Also, the abdominal fat of 0.13% was decreased and the muscle mass of 1.56kg was increased. For the change factors of physical fitness, cardiovascular endurance, muscular strength, muscular endurance, balance and flexibility excluding agility showed significant improvement after applying complex exercise training. The improvement of health fitness of the aged under this study was significantly effective to improve specified body functions which had been lowered by aging and insufficient physical activities. So, it is regarded that their health fitness is the important factor to improve the activity competence required for daily life and to lead healthy living by the improved activity competence. Henceforth, it needs to study more the complex composition of several sports, exercise intensity and the frequency based on the previous researches and studies. In addition, it needs to develop the complex exercise training in accordance with various characteristics such as a sex of the aged, an age, a physical fitness level, environment, a disease and the program in consideration of the efficacy and safety during training.
Objective : The purpose of this study was to analyze the effect of the elastic band on ballet arabesque based on kinematics analysis. Methods : To observe the effect of the elastic band, the availability of the elastic band during movement was set as the independent variable, and the dependent variables were set by using factors from two different categories such as motor mechanics and kinematics variables. For motor mechanics variable, the muscle activity and the center of pressure(COP)'s trajectory and velocity were used. Furthermore, the physical angle was used for kinematic variables. Data samples from the experiment was used to understand the correlation between independent and dependent variables while using paired samples t-test as a data analysis tool. Results : After analyzing the result of experiment, the usage of the Elastic band on ballet arabesque movement seemed to increase the activity of the agonistic muscle, which is mainly used for movement, and to improve the stability of the supporting leg by decreasing the trajectory and velocity of the center of pressure(COP). Moreover, the elastic band increased the level of elevation of the stretching leg with reducing the angle of the hip joint that resulted into a more stable movement and furthermore providing more beauty while standing on it. Conclusion : The movement training program while the using elastic band are expected to lead to appropriate muscular development and reduce the muscle imbalance, which usually occurs to dancers, during training with unfamiliar specific movements or strengthening muscular strength for a specific movement. In addition, this work is expected to be used as a training reference to understand and learn the fundamentals of movements of ballet and other dance fields.
Purpose: This study was conducted to investigate the muscle anti-fatigue effects of Allii tuberosi semen after long term administration. Materials and Methods: 4-6 weeks old ICR mice were used in this study and we administered the water soluble extracts of Allii tuberosi semen in the concentration of 1, 10 and 100mg/0.3ml to each 5 mice (ATS group) and same volume of normal saline was administered to 5 mice (control group) once a day for 90 or 120 days. After the administration we performed the swimming exercise test and the grip strength test. And we measured the concentration of glucose and the activity of lactate dehydrogenase in plasma regarded as biochemical indicator related with the muscular fatigue. Results: In swimming exercise test, all ATS groups showed increased time compared with relative control group after 90 days administration. But after 120 days adminstration 10 and 100mg/0.3ml ATS groups showed increased results. In grip strength test, all ATS group increased grip strength after 90 days administration and 10mg/0.3ml ATS group showed increased result after 120 days administration. All the results of plasma glucose didn't showed statistically significant difference after 90 and 120 days administration. In the plasma concentration of activity level of lactate dehydrogenase, 1mg/0.3ml and 10mg/0.3ml ATS groups showed decreased concentration compared with relative control group after 90 days administration. But after 120 days adminstration 1mg/0.3ml ATS groups showed decreased results. Conclusion: From this study we could find the anti-fatigue effect of Allii tuberosi semen in the muscle strength related test.
Purpose: This study examined the effects of the abdominal drawing-in maneuver (ADIM) on muscle activity in the trunk and legs while subjects walk on a ramp. Methods: The subjects were healthy adult males (n=15) and females (n=8) in their twenties. The subjects were asked to maintain the ADIM contraction for 15 minutes using a pressure biofeedback unit. Their muscle activity was then measured while ascending or descending the ramp with or without the ADIM contraction maintained. Activity in the sternocleidomastoid, splenius capitis, rectus abdominis, external oblique abdominal, transversus abdominis, erector spinae, vastus medialis, and vastus lateralis muscles was measured using surface electromyography (TM DTS, Noraxon, USA). A paired t-test was conducted using SPSS 18.0 (IBM) for statistical data processing. Results: Maintaining the ADIM contraction during ascension led to a significant increase (p<0.05) in muscle activity for the rectus abdominis, transversus abdominis, vastus medialis, and vastus lateralis, but a significant decrease (p<0.05) in muscle activity for the erector spinae, when compared to the same activity without the ADIM maintained. Furthermore, maintaining the ADIM contraction during descent led to a significant increase (p<0.05) in muscle activity for the rectus abdominis, external abdominal oblique, transversus abdominis, vastus medialis, and vastus lateralis, but a significant decrease (p<0.05) in muscle activity for the erector spinae, when compared to the same activity without the ADIM maintained. Conclusion: As a result of this study, it maintains the ADIM and reduces lumbar muscle activity at the waist and increases muscle activity in the legs when walking on a ramp. Therefore, maintaining the ADIM contraction during ramp walking is recommended as training to improve the function of patients' muscular skeleton.
This study used an unstable platform to change the support surface type and position of both lower limbs in order to determine changes in weight distribution and muscle including the vastus medialis, tibialis anterior, lateral hamstring, and lateral gastrocnemius of both lower limbs were evaluated during knee joint flexing and extending in a semi-squat movement in 32 hemiplegic patients. The support surface conditions applied to the lower limbs were divided into four categories: condition 1 had a stable platform for both lower limbs; condition 2 had an unstable platform for the non-hemiplegic side and a stable platform for the hemiplegic side; condition 3 had a stable platform for the non-hemiplegic side and an unstable platform for the hemiplegic side; and condition 4 had an unstable platform for both sides. The normalized EMG activity levels of muscles and weight bearing ratio of both sides in the four surface conditions were compared using repeated measures ANOVA. A significant increase was found in the weight support distribution for the hemiplegic side in flexing and extending sessions in condition 2 compared to the other conditions (p<.05). A statistically significant decrease in significant decrease in asymmetrical weight bearing in flexing and extending sessions was observed for condition 2 compared to the other conditions (p<.05). A similar significant decrease was found in differences in muscular activity for both lower limbs in condition 2 (p<.05). The muscular activity of the hemiplegic side, based on the support surface for each muscle showed a significantly greater increase in condition 2 (p<.05). An unstable platform for the non-hemiplegic side and a stable platform for the hemiplegic side therefore increased symmetry in terms of the weight support distribution rate and muscle activity of lower limbs in hemiplegic patients. The problem of postural control due to asymmetry in hemiplegic patients should be further studied with the aim of developing continuous effects of functional training based on the type and position of the support surfaces and functional improvement.
