  • Objective: This study was conducted to investigate the effects of resistant exercise on the gait performance of a patient with systemic lupus erythematosus (SLE) patient. Design: A case study. Methods: A 30-year-old male adult who had been diagnosed with systemic lupus erythmatosus (SLE) in April 2013, right middle cerebral artery infarction, and with left hemiplegia agreed to participate in this case study. Patient was unable to walk due to being affected with adynamia. Due to developing necrotizing vasculitis on the left lower extremity, patient underwent a myotomy on the left thigh. The patient was trained with a progressive resistant exercise program for 8 weeks. An intensity of 15 RM was used for the resistant exercises and the resistance level was increased progressively in order to improve the muscle power of the patient. Methods used to increase resistance included changing positions, providing mechanical resistance instead of manual resistance, transitioning from open kinetic chain to closed kinetic chain exercises, and changing the colors of the theraband to those with increase level of resistance. Outcome measures included the 5-repetition sit-to- stand test (5RSST), Timed Up & Go (TUG), and 10-meter walk test (10MWT). In addition, the GAITRite was used to assess the spatio-temporal gait variables, including gait speed, cadence, stride length of the left side, and double limb support pre and post-intervention. Results: The patient was able to perform sit-to- stand after two weeks of performing the resistant exercises. The patient was able to walk after 4 weeks, and the patient's overall gait performance had improved after 8 weeks. All of the variables had improved after each week. Conclusions: The results of this case study may be used to enhance future efforts to objectively evaluate resistant exercises during gait performance in persons affected by SLE.

  • Objective: This study analyzes the effect of angle conditions of rehabilitation equipment used for supporting hemiplegic patients on their rehabilitation training for standing action. The study was performed by adjusting the rear angle of seat inclination through a motion analysis. Background: Owing to a loss of muscle rigidity and degradation of muscle control ability, hemiplegic stroke patients suffer from asymmetrical posture, abnormal body balance, and degraded balance abilities due to poor weight-shifting capacity. The ability to shift and maintain one's weight is extremely essential for mobility, which plays an important role in our daily life. Thus, to improve patients' ability to maintain weight evenly and move normally, they need to undergo orthostatic and ambulatory training. Method: Using a motion analysis system, knee movements on both hemiplegic side and non-hemiplegic side were measured and analyzed in five angles ($0^{\circ}$, $10^{\circ}$, $30^{\circ}$, $50^{\circ}$, $70^{\circ}$) while supported by the sit-to-stand rehabilitation equipment. Results: The knee movements on both sides increased as the angle increased in angle support interval to support a hemiplegic patient's standing up position. In standing up interval, a hemiplegic patient's knee movement deviations on both sides decreased, and the movement differences between hemiplegic and non-hemiplegic legs also decreased as the angle increased. Conclusion: The results of this study showed that the rehabilitation effectiveness increases as the angle increases, leading to a balanced standing posture through the decrease of movement difference between hemiplegic and non-hemiplegic sides and an improved standing up ability through the increase of knee movement on both sides. However, angles higher than $50^{\circ}$ didn't provide a significant effect. Therefore, a support angle under $50^{\circ}$ was proposed in this study. Application: The results of this study are expected to be applicable to the design of sit-to-stand support equipment to improve the effectiveness of the rehabilitation process of hemiplegic patients.

  • Objective: The purpose of this research was to investigate the age-related changes in whole-body motor variability during sit-to-stand (STS) task. It has been reported that children perform motor tasks less accurately with greater variability as compared to adults. However, it is still unknown how they utilize the abundant degrees of freedom and accomplish voluntary actions. Uncontrolled manifold (UCM) analysis has been used to partition motor variabilities into two independent variability components, task-relevant variability (VORT) and task-irrelevant variability (VUCM). We investigated what differences exist between children and adults with respect to these two motor variability components in relation to motor development stages. Method: Ten 6-year-old children (height: 116.2 ± 4.3 cm, weight: 23.1 ± 3.9 kg, motor development assessment percentile score: 77.5 ± 18.6%), ten 10-year-old children (height: 138.7 ± 7.2 cm, weight: 35.8 ± 10.3 kg, motor development assessment percentile score: 73.9 ± 12.7%), and ten young adults (age: 23 ± 1.6 year-old, height: 164.3 ± 11.4 cm, weight: 60.8 ± 12.0 kg) participated in this study. Each participant performed STS ten times, and a motion capture system was used to capture the whole-body kinematics. Each segment centers of mass and the whole-body center of mass were calculated, and UCM analysis was used to quantify motor variabilities, VORT and VUCM. One-way ANOVA was used for statistical analysis. Results: We found that children produced more motor variabilities in VORT and VUCM in all three dimensions, anterior-posterior, medial-lateral, and vertical. As age increased, both, VORT and VUCM significantly decreased (p<.05). Conclusion: The greater VORT found in children compared to adults indicates that the repeatability over repetitions improves through development, while the greater VUCM found in children suggests that children better utilize the abundant degrees of freedom during STS compared to adults.

  • PURPOSE: The purpose of this study was to investigate the comparison of muscle activity and mechanical loading according to the angle of ankle joint during a sit-to-stand (STS) task. METHODS: Thirty-four young participants performed the STS in a randomized trial with the ankle joint at a neutral, 15 degrees dorsiflexion and 15 degrees plantarflexion angle in a fixed sitting posture with the knee in 105 degrees flexion. Muscle activity of the tibialis anterior (TA), rectus femoris (RF), biceps femoris (BF), and gastrocnemius medialis (GCM) was measured, and the parameters calculated in relation to mechanical loading were the STS-time, maximum peak, minimum peak, and total sum of mechanical loading. RESULTS: In the dorsiflexion position, the muscle activity of the TA and GCM showed a significant increase (p<.05), and the STS time, maximum peak and total sum of mechanical loading showed a significant difference compared to that in the neutral position (p<.05). In the plantarflexion position, the muscle activity of the RF and GCM showed a significant increase (p<.05), while that of the TA showed a significant decrease (p<.05) compared to that in the neutral position. And the minimum peak was significantly increased than the neutral position (p<.05), and the maximum peak and total sum of mechanical loading were showed significant difference compared with dorsiflexion position (p<.05). CONCLUSION: These results show that there is a difference in muscle activity and mechanical loading when performing the STS movement according to the change in the ankle joint angle.

  • PURPOSE: The aim of this study was to provide the standard value of the Five Times Sit to Stand Test (FTSST) measurement on the daily life independence of the elderly in Korea and examine the effects of this test on their daily lives. METHODS: This study was conducted on elderly people over 65 years of age living in Gyeongsangbuk-do, Korea. FTSST was performed while sitting position on a chair. The subjects were classified into independent and dependent living groups according to their lifestyle, and their influence was then examined through logistic regression analysis. To determine the usefulness and cut-off value of the FTSST, the analysis was performed using the ROC curve. RESULTS: The elderly were more likely to live in a group rather than independently as the FTSST time increased (p<.05) (OR=1.098). The area of the lower part of the ROC curve was .707, and as the FTSST increased, a subject was more likely to live in a group rather than independently (p<.05). The cut-off value was assigned to the point where both the specificity and sensitivity were at the coordinates. The sensitivity and specificity were .626 and .753, respectively at 15.62 seconds. CONCLUSION: The elderly in Korea are more likely to live a group-dependent lifestyle than live independently; the likelihood of this outcome is increased further for every additional second beyond 15.62 seconds. The loss of independence of daily life could be predicted based on the status of a subject's lower leg strength using the FTSST.

  • The purpose of this study is to examine the effect of stabilization, resistance exercise, and combined exercise for lumbar on balance and walking ability of elderly. This study selected 22 subjects of over 65 years old elderly women who satisfy the study condition from A, B and C Senior Citizen's Center, in Daegu. The subjects were divided into groups; 7 for resistance exercise group, 8 for stabilization exercise group, and 7 for combined exercise group(resistance and stabilization exercise). The exercises were conducted for 60min a day, three times a week for 12 weeks. Balance and walking ability were checked before the exercise, 6 weeks later, and 12 weeks later. First, all lumbar muscle strengthening exercises were effective for static balance which changed according to exercising period. In dynamic balance, the resistance exercise group showed significant improvement in sit to stand. Stabilization exercise group showed significant improvement in all factors. The combined exercise group showed significant improvement in sit to stand and timed up and go. There was no difference between the exercise types. Second, the resistance exercise group showed significant change in Cadence which changed according to exercising period. The combined exercise group showed significant improvement in all factors. Between the exercise types, combined exercise was a bit more effective than resistance exercise. According to the result of 12 weeks of lumbar muscle exercise, combined exercise is considered to be the most effective exercise to prevent fall as it helps balance and walking ability slightly more than other exercises. Therefore, this study can understand the risk factors for fall accidents that frequently occur among elderly and adopt the combined exercise to prevent fall which in turn will prevent secondary problems occur from fall accidents and improve quality of life of elderly.

  • Objective: The aims of this study were 1) to develop easy-to-use rhythmic balance training equipment for the elderly and 2) to investigate the effect of training with the equipment on balance and physical function. Method: Twenty-one elderly individuals (age: $75.4{\pm}3.34yrs$, height: $152.07{\pm}4.81cm$, weight: $58.35{\pm}8.34kg$) participated in this study. Each participant underwent balance and physical function testing before and after 12 weeks of training with the equipment. Y-balance (i.e. dynamic balance) and one leg static balance tests were used for balance testing, and timed up- and-down-stairs and five times sit-to-stand tests were used for physical function testing. A paired t test was used to determine whether there was a significant pre- and post-training difference. Results: The rhythmic balance training equipment provided a fun and motivating training program with age-friendly music, dance movements for lower extremity strength training, and touch screen controls with simple features. Post-training left foot dynamic balance was significantly greater (p<.05), and static balance with eyes open was significantly improved (p<.05) compared to pre-training. Completion of the timed up-and-down-stairs and the five times sit-to-stand tests was significantly shorter (p<.05) compared to pre-training. Conclusion: Training using the equipment developed in this study improved balance and physical function in elderly participants.

  • PURPOSE: The purpose of this paper is to provide a review of physiotherapy intervention for patients with COVID-19 during their hospital admission and post-discharge. METHODS: The recommendations and guidelines of physiotherapy management, medical management, and general information of the WHO, Australian Physiotherapist, European Respiratory Society, British Thoracic Society, and American Thoracic Society were reviewed. RESULTS: This paper contains general information on COVID-19, including medical management, and the importance of physiotherapy approaches including an assessment of the patients' function, such as the 6-minute walking test, five sit to stand or sit to stand for one minute to measure their function as their recovery journey. The patients' quality of life, anxiety, and depression should be considered. Physiotherapy management should be based on an assessment of the patient's presenting impairments, including inclusion and exclusion of physiotherapy intervention. The paper also approaches step by step with the disease progress, from an intensive care unit, the general ward in the acute phase, through to the rehabilitation ward if needed, and post-discharge as an outpatient.. CONCLUSION: The paper has a limitation due to the unknown factor of the natural history of COVID-19. Depending on the patients' recovery journey and the rehabilitation needed, any physiotherapy interventions should focus on what the patients' need on their journey to recovery, e.g., pulmonary, cardiac, neurological, and general rehabilitation. In addition, applying personal protection equipment for treating physiotherapists is a mandatory requirement because this protects from the transmission of COVID-19.
