There is currently no cure for MS; its treatment is based on symptom management. One way for symptom management is to have physical activity which has been shown to reduce the number, length, and duration of disease relapse and remitting. The opportunities for mobile health use have increased significantly in recent years, largely due to technological advances in mobile applications. This study aims to determine the information needed for designing a mobile application to increase the physical activity of patients with MS. Materials and Methods: This is a descriptive study that was done in two stages. Participants were a panel of experts. The data collection tool was a researcher-made questionnaire based on the Likert scale with confirmed validity and reliability (Cronbach’s alpha=0.79). Items with an ...

To date, no study has compared reaction time and anticipatory skill of athletes from open and closed skill-dominated sport. Accordingly, the present study investigated whether a difference exists in sensory-cognitive skills between these two different sport domains. Eleven volleyball players and 11 sprinters participated in this experiment. Reaction time and anticipatory skill of both groups were recorded by a custom-made software called SART (speed anticipation and reaction time test). This software consists of six sensory-cognitive tests that evaluate visual choice reaction time, visual complex choice reaction time, auditory choice reaction time, auditory complex choice reaction time, and anticipatory skill of the high speed and low speed of the ball. For each variable, an independent t-test was performed. Results suggested that sprinters were better in both auditory reaction times (P<0.001 for both tests) and volleyball players were better in both anticipatory skill tests (P = 0.007 and P = 0.04 for anticipatory skill of the high speed and low speed of the ball, respectively). However, no significant differences were found in both visual choice reaction time tests (P > 0.05 for both visual reaction time tests). It is concluded that athletes have greater sensory-cognitive skills related to their specific sport domain either open or closed.
