Quantitative postural sway assessment by computerized dynamic posturography in athletes with chronic ankle sprain and normal subjects in Kuwait

To identify quantitative postural sway assessed by unilateral stance test using computerized dynamic posturography in athletes with chronic ankle sprain and normal subjects in Kuwait. Retrospective case control study. Sports and balance clinics, Physical Medicine and Rehabilitation Hospital, Ministry of Health, Kuwait. Twenty six male athletes suffering from chronic ankle sprain and twenty two healthy individuals as a control group well-matched for age and sex were included in this study. Clinical assessment and computerized dynamic posturography. Mean centre of gravity [COG] sway velocity which displays COG stability with eyes open and eyes closed was computerized and assessed. A significant increase of mean [ +/- SD] COG sway velocity on left or right leg standing with eyes open and eyes closed of athletes with chronic ankle sprain as compared to control group was found [p< 0.05]. In addition, the mean [ +/- SD] percentage difference scores with eyes open and eyes closed in athletes with chronic ankle sprain was higher compared to control group [p<0.001]. Patients with chronic ankle sprain have a higher COG sway velocity and impaired postural sway compared to normal subjects. The unilateral stance test may be used to identify quantitative postural sway and balance in chronic ankle sprain. The ligamentous damage, ankle muscle strength deficits and proprioception deficits at the ankle joint may explain poor balance in ankle sprain

Effects of visual feedback balance training by using computerised dynamic posturography in patients with multiple sclerosis

To study the effects of the visual feedback balance training on the Berg Balance Scale [BBS] under static and dynamic conditions, the somatosensory, visual and vestibular systems by dynamic posturography before and after training program in patients with multiple sclerosis [MS]. Retrospective case training study. Physical Medicine and Rehabilitation Hospital, Ministry of Health, Kuwait. A total of 23 patients with MS were recruited. All patients were evaluated using both the BBS and the sensory organization test [SOT] using computerized dynamic posturography [CDP] before and three months after the training program. The SOT consists of six conditions and composite equilibrium score [CES]. CES [%] and SOT were calculated. Before training, all patients had a reduction of BBSS and parameters of the SOT. After training, a significantincrease of BBS [p < 0.05], all parameters of the SOT [p < 0.05] and CES [p < 0.001] were observed. Improvement in all parameters of the SOT after training program could be explained by change in the somatosensory system of the posture control system. Also, there is impairment of the somatosensory system, rather than a specific lesion of vestibular and/or visual systems
