purpose to examine the intra-rater reliability of knee movement data in sagital plane obtained from electrogoniometer (egm) in a basic, sport-specific task of karate. methods a total of 23 elite karate athletes (13 females and 10 males; mean age of 16.10±1.26 yrs) participated in this study. the task was defined as performing three consecutive zenkutsu-dachi in two sessions. the used egm was a ...

estimating the elbow angle using shoulder data is very important and valuable in functional electrical stimulation (fes) systems which can be useful in assisting c5/c6 sci patients. much research has been conducted based on the elbow-shoulder synergies. the aim of this study was the online estimation of elbow flexion/extension angle from the upper arm acceleration signals during adls. for this,...

We have focused on the problem of classification of motion frames representing different poses by supervised machine learning and dimensionality reduction techniques. We have extracted motion frames from global database manually, divided them into six different classes and applied classifiers to automatic pose type detection. We have used statistical Bayes, neural network, random forest and Ker...

the aim of this research was to determine the effect of contextual interference derived from self-regulation practice with regard to type of task on acquisition and retention of tracking tasks with an emphasis on meta-cognition hypotheses (cognition and meta-cognition phenomena). for this purpose, 24 right handed male and female students of yazd university (mean age: 22± 1.7) were selected via ...

christian zionism, as an extremist christian movement, based on certain literal interpretations of the holy scripture, tend to materialize its deterministic prophetical beliefs so that to provide the ground for the reappearance of the christ at the end of the world. on the basis of this, the movement believes that men ought to pass seven phases or destinies which will lead to the reappearance o...

The sit-to-walk (STW) movement is a functional task that challenges balance and co-ordination. There is a paucity of literature investigating the phases of this movement and its significance in a clinical rehabilitation context. Measuring phases of this movement may provide clinically applicable data for screening subjects for mobility problems and evaluating interventions. Fifty-six subjects f...

this research was performed to compare the effect of various levels of contextual interference (blocked, random and increasing practice schedules) on acquisition, retention and transfer of movement time error and cursor error in a complex motor – perceptual task. for this purpose, 30 female students (age range of 11 – 13 years) participated in a pretest (3 parts of 12 trials) and based on their...
