“…However, it should be noted that these results may be related to those observed in the mCTSIB test where changes of the CoP alignment are associated with forward displacement as the disease severity progresses. As in our study, Suarez [32] observed also a decrease in the limits of stability of early stages when compared with a control group. Jessop et al [33] observed also a decrease of the maximum excursion amplitude of the CoP displacement in individuals with mild to moderate PD stages, when compared to a control group.…”

Abstract-Progression of Parkinson disease (PD) increasessevere motor symptoms such as bradykinesia, tremor, gait disturbance and postural instability, interfering with patients' daily life autonomy. Clinical evaluation is based on specific Scales like Hoehn & Yahr (H&Y) or UPDRS scales. The main goal of the study was to identify motor changes in the kinematic parameters related to different stages of Parkinson's disease progression according to H&Y scale. A secondary goal was to determine more objectively the stage of the disease reducing the discomfort of scales subjectivity. Our sample integrated 103 patients (45 female and 58 male, 70.5±8.4 years) diagnosed with PD by neurologists specialized in movement disorders. Postural Behavior was evaluated using Computerized Dynamic Posturography equipment (Balance Master System). Postural behavior was based on posturographic analysis of the center of pressure (CoP) time series (corresponding to the vertical projection of the center of gravity) to determine kinematic parameter(s) considered suitable to identify postural behavior modification. The posturographic tests applied were: 1) modified Clinical Test of Sensory Interaction on Balance (mCTSIB); 2) Limits of Stability (LOS); 3) Rhythmic Weight Shift (RWS). The results, concerning four stages of the H&Y scale (I-IV), showed significant differences between groups/stages. Static balance parameters like velocity, total distance, amplitude and frequency of CoP sway, increase with disease severity. In early to medium stages (I-II) of the disease, CoP presents a projection backwards, while in stage IV, this projection showed a trend to change forwards. Concerning dynamic balance, LOS presents a reduction mainly in the forward direction in all stages. The directional control in anterior-posterior RWS decreases with disease progression.

“…In regards to balance, VR provides an avenue to implement many of the therapy strategies that have been established for physical and neurological recovery, including repetitive practice, self-observation, biofeedback and imitation of others movements. [35] An extensive evidence base has been established demonstrating the positive effects of utilizing VR for the treatment of balance deficits in neurologically similar patients, including stroke, [81][82][83][84][85][86][87][88][89][90][91][92] Parkinson's disease [80,93,94] and spinal cord injury. [35,36,95,96] Studies of varying levels of complexities in these populations have shown that groups utilizing VR have improved gait speed, standing endurance, and score higher than groups receiving the 'standard of care' on measures of posture, standing and higher level balance.…”

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.

“…Balance disorders in individuals with Parkinson's disease (PD) can occur at different stages of the disease, increasing their physical disability 1 . This can be justified by the impairment of the central nervous system's ability to process vestibular, visual, and proprioceptive afferences, which normally interprets them to generate the appropriate muscle responses that are responsible for the maintenance of body balance 2,3 .…”
