Objective: The aim of this study was to compare the effect of a period of therapeutic exercise and reflexology on pain intensity and range of motion in elderly women with knee osteoarthritis. Methods: 45 elderly women with osteoarthritis of the knee were purposefully selected and randomly divided into three groups of 15: therapeutic exercise, reflexology and control. The therapeutic exercise a...
Objective: The purpose of this study was to investigate the effect of dynamic knee valgus during overhead squat, on hip and ankle joints muscle strength and range of motion in basketball players. Methods: In this study, 35 healthy basketball players (with the mean age of 20.98± 1.99, height 183.27 ± 6.64 cm and mass 75.31 ± 9.24 kg), in the control group (n = 18) and dynam...
In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...
