Comparison of maximum strength, proprioceptive, dynamic balance, maximum joint angle of stability and instability ankle by Cumberland Ankle Instability Tool.

[Purpose] The purpose of this study was to investigate the factors of ankle instability by using Cumberland ankle instability tool (CAIT), which have been frequently used as ankle instability tools. The participants were divided into the normal ankle group and the instability ankle group. Maximum strength, proprioception, dynamic balance and maximum rage of joint motion were compared in order to find out factors of instability in the questionnaires.

Meta-Analysis of the Effects of Physical Modality Therapy and Exercise Therapy on Neck and Shoulder Myofascial Pain Syndrome.

Objectives: The main purpose of this study was to identify the effects of physical therapy modalities and exercise therapy on myofascial pain syndrome by assessing the degree of effect size (ES) and related variables.

Methods: Related studies published between 1 January 2008 and 31 December 2019were retrieved from national [KCI, RISS, National Assembly Library and DBpia ( = 405)] and international [PubMed, Embase, Google Scholar and Cochrane library ( = 1,600)] databases. According to the selection criteria, 25 studies were selected for review.

A study on muscle activity based on the ankle posture for effective exercise with indoor horse riding machine.

[Purpose] Although much researches have been conducted on the hippotherapy, the intervention methods of the previous studies focus on the pelvis posture. Thus, this study analyzed the electromyogram (EMG) of trunk muscle and lower limb muscle to analyze the kinetic factors. Based on the analysis, this study aims to compare the muscle load and suggest effective exercise method.

Influence of muscle activation of posterior oblique sling from changes in activation of gluteus maximus from exercise of prone hip extension of normal adult male and female.

[Purpose] There have been many study ipsilateral erector spinae in regard of prone hip extension (PHE). However, mediating methods have been focusing on the reinforcement of gluteus. Hereupon, this study is intended to identify how an increase of gluteus maximus influences on posterior oblique sling (POS) and suggest a mediating method to effectively reinforce them.

Influence of ocarina practices on lung function of healthy middle-aged females in Korea.

[Purpose] The objective of this study is to identify the influence of ocarina practices on the lung function of a group of healthy female ocarina players aged 40 and above in comparison to an age-matched group of females with no experience with ocarina playing. [Participants and Methods] Spirometry measurement has been conducted on both groups of 35 healthy females aged 40 and above, one with regular participation in ocarina practices (experimental group) and the other without (control group). [Results] FEV and FEV/FVC values of those in the experiment group who practiced ocarina on a regular basis turned out to be significantly higher than the control group, and there was no significant difference on FVC.

The effect of the trunk and gluteus maximus muscle activities according to support surface and hip joint rotation during bridge exercise.

[Purpose] The purposes of this study were to strengthen gluteus maximus and trunk muscles depending upon the hip joint direction by bridging exercise on an unstable and stable surface, and to suggest an intervention method for efficient and selective exercise. [Participants and Methods] The test measured the muscle activities with the external rotation and internal rotation of 25 degrees and hip joint neutral position of 0 degree on a stable and unstable surface each exercise 3 times for 9 seconds. [Results] External oblique abdominis showed a higher muscle activity on the unstable surface and internal rotation.
