“…In each of these studies, it was reported that individuals with a concussion showed more balance instability in the dual task situations than the single task and also adopted a more conservative gait strategy than their matched, control counterparts Parker, Osternig, van Donkelaar, & Chou, 2007). Chou et al (2004) similarly found that the concussed individuals had a slower gait velocity and shorter stride length. Parker and colleagues noted that the concussed subjects showed a slower gait on day two than they did on the final testing day (day 28) (Parker, Osternig, van Donkelaar, & Chou, 2007).…”

Concussion has a well-defined, acute effect on motor control with alterations in gait documented up to thirty days post injury. There is a dearth of research examining the chronic effects of concussion on gait. The purpose of this investigation was to examine the effects of concussion in the gait patterns of young adults with and without a history of concussion during single and dual task paradigms. Individuals with (n=28, mean 6.32 years post injury) and without (n=40) a concussion history completed a battery of gait conditions during single and dual-task conditions.Normalized velocity, step length, stride width, number correct from cognitive task, time in single leg stance, and time in double leg stance were the variables of interest. Gait was analyzed using a GAITRite Electronic Walkway system and the Brooks visuospatial cognitive task was used to index cognition. Data analysis was assessed with multiple two-way, repeated measures ANOVAs and correlation analyses. The current investigation found that individuals with a history of concussion spent significantly greater time in double leg stance, significantly decreased time in single leg stance and had slower gait velocity. There was also a significant negative correlation between number of concussions and time in single leg stance and a positive correlation between number of concussions and time in double leg stance double stance percent.These findings suggest that individuals with a history of concussion adopt a more conservative gait strategy, perhaps to reduce the risk of further injury.

“…[56,68] Dynamic deficiencies have also been described by these methods, and include slowed, maligned or hemiparetic gait, [54,67,69] balance losses during normal gait [54,67] and difficulty stepping over objects during normal gait. [70] Some assessment devices, such as the SMART Balance Master, include several of the aforementioned computerized evaluations as part of one device, and are used by therapists to qualify, quantify and track balance abilities and deficits throughout the rehabilitative stay. The results of all of assessments, no matter the complexity, are shared throughout a multidisciplinary team (i.e.…”

Virtual reality-based therapy for the treatment of balance deficits in patients receiving inpatient rehabilitation for traumatic brain injury

Thesis directed by Assistant Clinical Professor Cynthia Harrison-Felix.Balance deficits are one of the most commonly occurring and physically limiting sequlae that result from more severe traumatic brain injury (TBI). The purpose of this study was to evaluate the effectiveness and applicability of using a commercially available virtual reality (VR) system as a treatment of these deficits for patients receiving inpatient rehabilitation for a primary diagnosis of TBI by conducting analyses of data collected as part of a pilot randomized controlled trial. The aims of this thesis were: (1) to examine the relationships between treatment received (VR or Extra Standard of Care) and static and dynamic balance changes over time; (2) to assess the predictive validity of the VR game scores on static and dynamic balance; and (3) to investigate dose response relationships between study treatments and changes in static and dynamic balance.Results indicate that patients receiving either treatment demonstrated significant balance improvements over time; however, neither treatment condition was found to be significantly better than the other. Scores from the VR balance games were found to have some moderately strong associations with the standardized assessment of static balance, with less strong relationships between VR scores and standardized assessments of dynamic balance. The results did not suggest the existence of any relationship between the amount of treatment received and changes in standardized assessments of balance. These data provide an essential first step in the establishment of the use of iv commercially available VR systems as effective tools for treating balance deficits for patients with TBI.The form and content of this abstract are approved. I recommend its publication.

“…A study by Harris et al 21) examined the relationship between BBS and falls in 99 community-dwelling individuals with chronic stroke and found that performance on the BBS did not differ between those with high and low risks of falls. Some previous studies have also shown floor and ceiling effects in individuals following stroke, although another study indicated that BBS could always predict fall risk in stroke patients and that falls occurred during walking 22,23) . The lack of a meaningful interpretation of a score indicating a specific function level has led to further investigations using Rasch analysis.…”
