Abstract Background: The Dynamic Gait Index is a useful scale that has been evaluated for its reliability in patients with vestibular disorder, elderly people and, in chronic stroke population but its reliability has not been evaluated yet in sub-acute stroke patients with eye movement disorders. So the purpose of this study was to evaluate the intra-rater and inter-rater reliability of the Dynamic gait index to measure the dynamic balance, gait and risk of fall in sub-acute stroke population with eye movement disorders.Methods: A total of 30 (18 male, 12 females) stroke patients in the sub-acute phase suffering from eye movement disorders were recruited for this reliability study. Two experienced Physical therapists assessed the intra-rater and inter-rater reliability of the Dynamic gait index in two testing sessions three days apart. In the later session, two raters assessed the patients’ performance simultaneously on the Dynamic gait index. Data analysis was done at 95% confidence interval using the intra-class correlation coefficient (ICC2, 1). A significance level was set at P-value <0.05.Results: Mean tests scores by rater 1 in the first and second assessment were 17.4±2.04 and 18.0±2.05. Mean tests score by rater 2 in the second assessment were 18.6±2.06. Intra-rater (ICC=0.86, CI=0.73-0.93) and inter-rater (ICC=0.91, CI=0.83-0.96) reliability of total DGI scores was found good to excellent while intra-rater (ICC=0.73-0.91) and inter-rater (ICC=0.73-0.93) reliability of individual items of DGI scores were ranged from moderate to good. Item 8 (steps) showed lowest reliability (ICC=0.73). The significant difference was seen in total and individual scores (P<0.001) of DGI scale in both intra-rater and inter-rater reliability.Conclusions: The Dynamic gait index is found clinically a reliable tool to objectively measure dynamic balance, gait and risk of fall in sub-acute stroke individuals with eye movement disorders. The intra-rater and inter-rater reliability of the total DGI scores was found good to excellent; whereas intra-rater and inter-rater reliability for individual items of DGI were varied from moderate to good.

Introduction: Visual abnormalities and manual motor control have been studied extensively after stroke, but an understanding of oculomotor control post-stroke has not. Recent studies have revealed that in visually guided reaches arm movements are planned during eye movement execution, which may contribute to increased task complexity. In fact, in healthy controls during visually guided reaches, the onset of eye movement is delayed, its velocity reduced, and endpoint errors are larger relative to isolated eye movements. Our objective in this experiment was to examine the temporal properties of eye movement execution for stroke patients with no diagnosed visual impairment. The goal is to improve understanding of oculomotor control in stroke relative to normal function, and ultimately further understand its coordination with manual motor control during joint eye and hand movements. We hypothesized that stroke patients would show abnormal initiation or onset latency for saccades made in an eye movement task, as compared to healthy controls. Methods: We measured the kinematics of eye movements during point-to-point saccades; there was an initial static, fixation point and the stimulus was a flashed target on a computer monitor. We used a video-based eye tracker for objective recording of the eye at a sampling frequency of 2000 Hz (SR Research, Eyelink). 10 stroke subjects, over 4 months from injury and with no diagnosed visual impairment, and 10 healthy controls completed 432 saccades in a serial fashion. Results: Stroke patients had significantly faster onset latencies as compared to healthy controls during saccades (99.5ms vs. 245.2ms, p=0.00058). Conclusion: A better understanding of the variations in oculomotor control post-stroke, which may go unnoticed during clinical assessment, may improve understanding of how eye control synchronizes with arm or manual motor control. This knowledge could assist in tailoring rehabilitative strategies to amplify motor recovery. For next steps, we will perform objective eye and hand recordings during visually guided reaches post-stroke to better understand the harmonization or lack thereof after neurologic insult.
