It is feasible to use a functional virtual environment for investigation of dual tasking. Different gait strategies, including an increase or decrease in gait speed, can be used to cope with the increase in cognitive demands required for dual tasking.

We have developed a mixed reality system incorporating virtual reality (VR), surface perturbations and light touch for gait rehabilitation. Haptic touch has emerged as a novel and efficient technique to improve postural control and dynamic stability. Our system combines visual display with the manipulation of physical environments and addition of haptic feedback to enhance balance and mobility post stroke. A research study involving 9 participants with stroke and 9 age-matched healthy individuals show that the haptic cue provided while walking is an effective means of improving gait stability in people post stroke, especially during challenging environmental conditions such as downslope walking.

Purpose: This study describes the development of a standardized assessment toolkit (SAT) and associated clinical database focusing on sensorimotor rehabilitation in three stroke rehabilitation units (SRUs). Implementation of the SAT was confirmed using objective measures of clinician adherence while exploring reasons for varied adherence. Method: Participants were patients post-stroke admitted for inpatient rehabilitation and clinicians from the three SRUs. A collaborative and iterative process was used to develop the SAT. Implementation was measured by clinician adherence, which was charted by means of assessment entries in patient records and transferred to the clinical database. Reasons for lower adherence were interpreted from therapist data logs at one SRU. Results: The SAT consisted of 25 assessment tools. Clinician adherence to a subset of the tools ranged from 33% to 99% at admission and from 28% to 94% at discharge. At one site, lower adherence among the tools was explained by patient-related factors (1%-36%) and protocol or logistical reasons (0%-7%) at admission; missing data ranged from 0% to 3%, except for the Montreal Cognitive Assessment (17%). Conclusions: In this pragmatic study, objective measures of clinician adherence demonstrated the feasibility of implementing an SAT in daily practice. Moreover, the reasons for lower adher ence rates may be related to the patients, protocol, and logistics, all of which may vary with the assessment tool, rather than clinician compliance.
