The axe kick, in Olympic style taekwondo, has been identified as the most popular scoring technique aimed to the head during full contact competition. The first purpose of this study was to identify and investigate design issues with the current World Taekwondo Federation approved chest protector. A secondary purpose was to develop a novel chest pr...

[Purpose] This study sought to determine the prevalence of work-related musculoskeletal disorders (WRMDs) their associated work risk factors and the coping strategies used to reduce their risk among physical therapists in Korea. [Subjects] Korean physical therapists with at least 1 year of working experience. [Methods] A self-administered questionn...
Article
[Purpose] The purpose of this study was to examine between an hospital environment and a outdoor environment of differences the gait velocity and balance ability of hemiplegia patients, who had received an eightweek rehabilitation treatment for gait and balance [Subjects] A total of 27 hemiplegia patients participated. [Methods] Before and a the re...

[Purpose] The purpose of this study was to investigate whether a cranio-cervical flexor exercise is effective at improving the cross-sectional area (CSA) of the longus colli (LC), the absolute rotation angle (ARA) and neck disability index (NDI) of patients with chronic neck pain. [Subjects] The subjects of this study were 35 patients who had chron...
Article

[Purpose] The purpose of this study was to compare a conventional one leg standing exercise and a device-using one leg standing exercise in order to improve hemiplegia patients gait and balance function. [Subject] The subjects of this study were 30 patients who were hospitalized with hemiplegia resulting from stroke. The final number of participant...

... The high prevalence of muscle dysfunction in chronic WAD dictates that it be properly assessed in order to identify its presence, guide treatment, and monitor change over time. While a reliable and valid means of assessing deep cervical flexor function has been established in the WAD population [15,16,18,19,[26][27][28], no such measure exists for assessing general neck strength in a variety of movement planes in this patient group. The most standardized and objective means of assessing cervical strength is fixed-frame dynamometry (FFD), in which the load cell is fixed against a stable surface such as a wall or frame [29]. ...
... Of the 211 articles examined for inclusion, 12 studies [5,13,14,[16][17][18][19][20][21][22][23][24] met the criteria for this systematic review, including 11 observational studies and one mixedmethods study (Table 1). These studies were conducted in numerous geographical locations including Nigeria, India, United States of America, United Kingdom, Korea, Australia, Italy, Kuwait, and Israel. ...
... Dehail et al. revealed the negative correlation between the amplitude of trunk flexion during STW and isokinetic strength of the knee extensors (Dehail et al., 2007). Choi et al. reported that the STW motion was affected by foot position and chair height, and changes of CoM horizontal momentum were the most efficient when rising from a chair height of 120% of the leg length (Choi et al., 2013). ...
... Strategies available to restore WB symmetry can be based on the use of feedback systems [12], wedges/lifts for shoes [13], functional electrical stimulation [14], hippotherapy simulators [15] and ankle-foot orthosis [16]. Another alternative is the use of therapeutic exercises, which is a more accessible approach, as it requires fewer and relative cheaper equipment and is easy to reproduce in clinical practice [17][18][19][20][21]. ...
... This could be because the muscle tone of these muscle groups was comparable to normal at baseline. The total stretching time of 15 minutes has been considered sufficient for lengthening shoulder muscles with spasticity (Young et al, 2014). The stretching time for each muscle group in the present study was 30 seconds for each stretch, repeated 3-5 times over 18 sessions. ...
... In recent years, World Taekwondo incorporated modern technology into the discipline, i.e., the Protector Scoring System (PSS), the instant Video Replay System (VRS), and relevant competition rule changes [12][13][14][15][16]. The latest revisions in Olympic taekwondo rules penalize non-fighting actions, the presence of "phantom striking", and unnecessary leg elevation; limit possible fouls; and modify the scoring system. ...
... The feet are located at the far end of the body, but they play an essential role in the kinematic chain (Pratt 2000); they transmit the load generated during the movement and form sufficient body support to enable the body to complete standing or walking. Appropriate insoles can support the balanced weight distribution of the isolated area and arch of the foot, effectively reduce the shock, thereby alleviating pain and unstable joint movement, reducing muscle activity, and increasing exercise capacity (Lee et al. 2014). ...
... In this category, we included studies with experimental conditions that incorporated movement by an animal as part of the intervention, such as while horseback riding (e.g., Lechner et al., 2007;Kim et al., 2014;Alemdaroglu et al., 2016;Abdel-Aziem et al., 2022). We determined that 17.44% (n = 30) of the studies controlled for movement as a specific factor. ...
... There are many factors promoting motor improvement in children with CP [4,5]. Effectiveness of various types of therapy intended for patients with CP was assessed in many studies [4][5][6][7][8][9][10][11][12][13]. However, most of these did not provide solid evidence related to effectiveness due to the heterogeneity of the study groups, other limitations associated with the type of therapy provided, and the duration of the rehabilitation program [4][5][6][7][8]. ...
... Postural sway is an indicator of displacement and motor corrections to maintain the COM within the BOS (Golriz et al., 2012). Previous investigations have shown that postural sway measures derived from center-of-pressure (COP) displacements during quiet standing are related to postural instability induced by muscle fatigue (e.g., Nam et al., 2013;Singh et al., 2009). The COP-based postural sway measures are also sensitive to demonstrate differences with altered visual, vestibular, and/or somatosensory inputs (Hansson et al., 2010;Riley and Clark, 2003), which can be negatively affected by prolonged exposure to WBV. ...
