Subacromial space is anatomically bounded to the acromion and the humeral head in consists of the superficial glenoid fossa. By narrowing the subacromial space, this is likely to occur such as rotator cuff injury and shoulder impingement syndrome. Therefore, the aim of this study was by comparison analysis to distance according to subacromial space the abduction angle of the shoulder joint to using ultrasonography. Thirty healthy adult males were recruited and agreed to participate as the subject in this study. This study was single group repeated measurements design and measured subacromial space according to angle of the shoulder abduction setting to 0°, 30°, 60° and 90° using ultrasonography. All measurements was used one-way repeated ANOVA to analysis difference between the variables. The result of study, there were significant differences among shoulder abduction 0°(11.30 mm), 30°(9.40 mm), 60°(8.01 mm) and 90°(7.10 mm). In conclusion, current study confirmed that subacromial space had an effect on the angle of shoulder abduction. Clinically it is considered that ultrasonography measurement of subacromial space helps to the differential diagnosis of rotator cuff injury and shoulder impingement syndrome.Keywords

Objectives This study aims to investigate the effect of pennation angle and surface Electromyography (sEMG) activity of medial gastrocnemius on different heights of high heels by using ultrasonography and sEMG. Methods/Statistical Analysis: Twenty eight healthy young females participate in this study. In order to measure the pennation angle and sEMG activity of medial gastrocnemius, we instructed subjects to stand barefoot and wearing two high heels (5 cm and 10 cm). We measured ultrasonography and sEMG activities for three times on three conditions (barefoot, 5 cm, 10 cm) repeatedly and used the mean of measurement values. One-way repeated ANOVA was used to see the difference of individual intervention and Bonferroni’s correction for post-hoc was used to that. Findings: Pennation angle and sEMG activities in medial gastrocnemius showed significant differences on three conditions (barefoot, 5 cm, 10 cm). Improvements/Applications: Furthermore, measurement of muscle activity using ultrasonography is considered useful way because pennation angle and sEMG activity in medial gastrocnemius increased in accordance with the increasing height of heels identically.Keywords

Objectives: The purpose of this study was to vibration and auditory stimuli affected the sense of ankle, knee, and hip joint position. Methods/Statistical Analysis: 40 healthy male and female adults who did not undergo an operation for diseases relevant to ankle, knee and hip joints were recruited for this test. By dividing experiment group into auditory stimulus group, vibration stimulus group, auditory, vibration stimulus group, sense of position for ankle, knee and hip joints was measured and for control group, sense of position for ankle, knee and hip joints was measured without any intervention. In order to give excitation arousal to auditory stimulus group and vibration stimulus group, cheerful music was played to them and to give vibration stimulus to vibration stimulus group and auditory, vibration stimulus group, vibration stimulus was given to them. Test subjects were directed to remember target angle through exercise of 5 times including ankle joint 20o, knee joint 30o and hip joint 95o and then stop exercise when they thought to arrive at the first remembered angle after taking a rest. As measurement tool, isokinetic muscular strength test equipment was used. Findings: In auditory stimulus group, significant difference was represented in ankle joint and in vibration stimulus group (p<.05), such difference was represented in ankle, knee and hip joints (p<.05). However, its mean value did not show any significant difference (p>.05). Improvements/Applications: As a result, this research has proved that vibration stimulates the ankle, knee, hip joint position sense and auditory stimulation of the senses is the effect on the position of the ankle stimulation.

Background/Objectives: Core stability means muscular control on the back regions. Lumbar multifidus is important for stabilization in back region. To demonstrate how multifidus activation would be changed in the various positions. Methods/Statistical Analysis: Thirty healthy males were recruited for the study. The researchers educated the participants how to make the right positions, which consists of the prone, the side lying, and the sitting position. The researchers measured the subjects' lumbar multifidus two times randomly using the ultrasonography. The transducer that is rectangular and has flat surface used 7-10MHz with a 50mm penetration depth. The raw data was analyzed using one-way repeated measures ANOVA to compare the positions. Findings: In the prone position, the lumbar multifidus' thickness was 22.7cm, whereas in the sidelying and sitting position, the lumbar multifidus thickness was 19.4cm and 20.0cm. It means that the Lumbar multifidus more activated in the prone position than other positions. Among those positions, if lumbar multifidus exercise is needed for patients who do not have any kind of lumbar pain, the prone position would be the best position for lumbar multifidus exercise to the patients. There were only few studies about comparing multifidus activation in various positions, but even in previous studies, no studies examined that how the lumbar multifidus worked in those three positions. Thus, the study proved that in which positions the lumbar multifidus activates more. Application/Improvements: Many patients need to core muscles exercise for their low back pain. In that case, doing lumbar multifidus exercise in the prone position would be the best position.Keywords

Background/Objectives: The purpose of this study was to identify the highest activation in Vastus Medialis (VMO), Vastus Lateralis (VL) and Rectus Femoris (RF) while performing various squat exercises to create an effective exercising method.
Method/Statistical Analysis:40 healthy subjects (males 23, females 17) from S University were recruited. Subjects performed four different types of squats; General Squats (GS), Instability Squats on an unstable surface (IS), Knee Adduction Squats (KAS), and Wall squats (WS). The difference in the activation of VMO, VLO and RF were recorded during the various exercises were analyzed and recorded with the EMG.
Findings: Measurements of all the experiments were analyzed using one-way ANOVA. Within these results, RF showed the most activation during (WS) and the least activation during (KAS). However, there were no significant differences found between (GS) and (IS). VLO showed the most activation during (GS). On the other hand, there were no significant differences found within (IS) and (WS). In addition to our results, VMO showed the least activation during (KAS). All three muscles displayed different activation patterns during each squat exercise.
Improvements/Applications: Considering these findings, this study may help to design a more effective exercise for specific muscles when strengthening the leg muscles.

Background/Objectives: The purpose of this study is to compare the change of thickness of serratus anterior muscle to different angles of knee flexion when knee push up plus (KPP) exercise is conducting on an unstable surface (sling).
Method/Statistical Analysis: There were 30 healthy young male and female students randomly selected and divided into 3 different groups along different knee flexion angles on an unstable surface (sling). The three groups of ten did KPP exercises on the sling. The muscle was measured before and after the exercise.
Findings: All three groups showed some changes in the thickness of the muscle. The group with the biggest change was the 60° knee flexion, followed by 75° and 90° groups.
Improvements/Applications: Based on the results, all experimental groups showed some differences with KPP exercise conducted on an unstable surface (sling) and especially the group with the lowest angle had the most effect. Therefore, it is concerned that a lower knee flexion angle can be more effective on the KPP exercise.
