Purpose: Assessing physical strength and muscle mass is crucial, but many methods rely on specialized equipment, which can be challenging. In situations where a quick and straightforward test is needed, the sit-to-stand test (STST) proves useful. Although several studies have investigated STST and muscle mass separately, the actual correlation between these two factors has not been extensively researched. Hence, the objective was to comprehensively investigate the correlations between the different tests. Methods: The study participants consisted of 20 healthy young men in their 20s. In this study, measurements were taken for muscle mass, the five-times sit-to-stand test, the 30-second sit-to-stand test, and the 1-minute sit-to-stand test. The results of each test were analyzed using Pearson's correlation analysis. Results: Although no significant correlation was found between muscle mass and STST, interestingly, significant correlations were observed among the different types of STST. Conclusion: The STST is a rapid and straightforward test used to assess lower limb strength and balance ability in individuals. However, there is a dearth of research on STST conducted in domestic settings. Based on the findings of this study, further research is necessary to establish age- and gender-specific reference values for STST. This will allow its broader application, encompassing not only older adults and patients but also healthy individuals.

Purpose: The study aims to examine the effects of the proprioceptive neuromuscular facilitation pattern exercise and scrambler therapy on pain, range of motion (ROM), and shoulder dysfunction in breast cancer patients. Methods: In total, 30 breast cancer patients were recruited and randomized to group I (n = 10), group II (n = 10), and group III (n = 10). Pain was measured using a visual analogue scale, ROM was measured using a goniometer, and shoulder dysfunction was measured using a shoulder pain and disability index. Group I practiced the proprioceptive neuromuscular facilitation pattern exercise and underwent scrambler therapy, group II underwent scrambler therapy only, and group III practiced the proprioceptive neuromuscular facilitation pattern exercise only. Results: A within-groups comparison showed that all groups demonstrated significant differences in pain, ROM, and shoulder dysfunction after the experiment (p<0.05). Further, according to a comparison of the three groups, group I showed a more significant difference in effectiveness than groups II and III in terms of pain, ROM, and shoulder dysfunction before and after the experiment (p<0.05). Conclusion: This study showed that the proprioceptive neuromuscular facilitation pattern exercise and scrambler therapy are effective in treating pain, ROM issues, and shoulder dysfunction in breast cancer patients.

Purpose: The aim of this study is to compare the immediate effects of weight-assisting methods on vastus medialis oblique (VMO) and vastus lateralis (VL) muscle activation, on the VMO/VL muscle activation ratio, and on muscle onset time in healthy subjects when ascending stairs. Methods: Healthy participants were randomly assigned to the belt group (n = 11), hand group (n = 11), and control group (n = 11). In the belt group, a belt was wrapped around the sacrum and pulled forward with both hands, moving the center of weight forward, while ascending stairs. The hand group grasped the hips with both hands and climbed stairs, assisting their weight from the rear and moving the center of weight backward, and the control group climbed the stairs without any intervention. Results: Muscle activation of the VMO decreased significantly after the intervention in the belt and hand groups, and activation of the VL muscle in both groups showed a greater decrease than that of the VMO muscle. Further, the VMO/VL muscle activation ratio increased significantly, with an improvement shown in the order of the belt group, hand group, and control group, while muscle onset time also improved in the order of the belt group, hand group, and control group. Conclusion: The belt group demonstrated the greatest effect across all dependent variables, confirming that in clinical practice, these two weight-assisting methods are more effective interventions during stair ascent for patients with knee joint instability, pain, and imbalance than no assistance.

Purpose: This study aims to examine the functional difference in the long and short heads of the biceps brachii by investigating the onset time of muscle contractions in the biceps brachii in the supination motion according to whether the flexor of the elbow joint is excluded. Methods: This study was conducted with 21 healthy men aged in their 20s. While performing forearm pronation at an elbow flexion angle of 90 degrees, the onset time of muscle contractions in the long and short heads of the biceps brachii was measured and compared in a posture where the humerus is placed on a table and the posture is lifted against gravity. Using an independent samples t-test, the difference in the onset time of muscle contractions in the long and short heads of the biceps brachii was analyzed. Results: The onset time of the long head was shorter if the flexor activity of the elbow joint was excluded, while that of the short head of the biceps brachii was shorter if it was not excluded. Conclusion: It is noted that the long head of the biceps brachii mainly functions as a supinator muscle, while the short head of the biceps brachii plays a role in stabilizing and maintaining flexion of the elbow joint.

Purpose: The aim of this study is to determine the effects of gastrocnemius stretching with talus-stabilizing taping on ankle dorsiflexion and subtalar joint pronation during walking. Methods: In total, 26 subjects with limited ankle dorsiflexion were equally divided into two groups: a gastrocnemius stretching with talus-stabilizing taping group (13 subjects) and a gastrocnemius stretching group (13 subjects). They were assessed according to ankle dorsiflexion and subtalar joint pronation during walking before and after an intervention, which involved two types of gastrocnemius stretches performed three times a week for six weeks. Results: Ankle dorsiflexion was significantly increased in both groups (p<0.05), though the gastrocnemius stretching with talus-stabilizing taping group showed a significantly greater improvement in ankle dorsiflexion than the gastrocnemius stretching group (p<0.05). However, subtalar joint pronation showed no difference between the two groups before and after (p>0.05), also between groups (p>0.05). Conclusion: Gastrocnemius stretching with talus-stabilizing taping is a useful stretching exercise that improves ankle dorsiflexion during walking in subjects with limited ankle dorsiflexion movement.

Purpose: This systematic review aims to determine whether robot-assisted training is more effective in gait training for persons with subacute hemiparetic stroke. Methods: This study adopted a systematic review study design focused on subacute hemiparetic stroke, and four core academic databases were searched until June 11, 2021, for relevant studies, including PubMed, Embase, the Cochrane Library, and ProQuest Central. The review included randomized controlled trials (RCTs) evaluating the effects of robotic-assisted training on gait performance in persons with a diagnosis of subacute hemiparetic stroke. The selected RCT studies were qualitatively synthesized based on the population, intervention, comparison, outcome, settings, and study design (PICOS-SD). Results: The study selected five RCTs involving 253 subacute hemiparetic stroke patients and performing robotic-assisted gait training using the following devices: the Lokomat, Morning Walk, Walkbot, ProStep Plus, or Gait Trainer II. Five RCTs were eligible for the meta-analysis after quantitative synthesis, and the results showed that the robot-assisted gait training group had a greater gait performance than the control group based on the 10-meter walk test, Berg balance scale, Rivermed mobility index, functional ambulation category, and modified Barthel index. Conclusion: The results of this study showed that the gait performance of subacute hemiparetic stroke patients changes throughout robot-assisted gait training, but there were no indications that any of the clinically relevant effects of robot-assisted training are greater than those of conventional gait training. Further, the small sample size and different therapeutic intensities indicate that definitive conclusions could not be made.

Purpose: The aim of this study is to provide basic information to create an efficient training program to improve shoulder stability and function in patients with injuries and in patients having undergone surgery of the supraspinatus and infraspinatus muscles, which have a relatively high incidence of injury in shoulder joint disease. Further, independent activities of the supraspinatus and infraspinatus muscles were investigated according to forearm rotation and the neutral and lateral rotation postures. Methods: The activities of the supraspinatus and infraspinatus muscles were measured using surface electromyography in 22 healthy adults in Busan, and isokinetic muscle strength measurement equipment was used to measure muscle strength during shoulder lateral rotation. The subjects performed lateral rotation of the shoulder in three different forearm postures (neutral, supine, prone) to measure shoulder muscle activity and lateral rotation strength. Results: The independent activity ratio (% Isolation) of the supraspinatus and infraspinatus muscles during lateral rotation of the shoulder joint demonstrated a significant difference (p<0.05) according to the change in forearm posture. Conclusion: The supraspinatus muscle showed independent activity ranging from highest to lowest in the order of pronation, neutral, and supination of the forearm, while the independent activity of the infraspinatus muscle ranged from highest to lowest in the order of neutral, supination, and pronation of the forearm. Therefore, the most active forearm positions for the supraspinatus and infraspinatus muscles are pronation and neutral, respectively.
