Abstract Dual task training benefits older adults by improving their balance and gait parameters. There is strong evidence suggesting its usefulness in reduction of falls with reduced falls risk. Current interventions for dual task training include exercises with cognitive exercises. There exists limited evidence for the use of Virtual Reality (VR) in training for dual tasking. Our study sets out to evaluate the usability and feasibility of an immersive VR dual tasking platform for older adults. An immersive VR dual tasking training platform for older adults was developed in conjunction with the engineers for this pilot study. The cognitive task involves training of executive function through an immersive 3-dimensional game where the participants have to follow instructions to catch and avoid certain specified objects. The motor task involves walking on a motorized treadmill at a preset speed. The two tasks were incorporated into a single platform with a training protocol over twelve sessions. We evaluated for side effects from using this immersive VR device and tolerability of the training protocol. The mean age of the participants is 62.9(±3.0)years old. Their mean comfortable gait speed is 1.27m/s. There were no falls throughout the entire training program. Participants tolerated the training protocol well with only 0.83% (1/120 training sessions) experiencing lower muscle ache/pain. The most common adverse effect from the immersive VR environment was tiredness – which made up 88% of all the adverse effects. However, this did not prevent participants from completing the training. The mean rating on the Borg Scale of perceived exertion is fairly light. The VR platform and training protocol is safe and feasible for use in healthy older adults. We aim to conduct a clinical trial using this VR dual tasking platform in older adults to assess for clinical benefits in falls preventions, improvements in gait parameters and cognitive scores.

Abstract Introduction Patients after hip arthroplasty (THR) load the feet asymmetrically during standing or walking. Many reports indicate effectiveness of the Virtual Reality (VR) training in reeducation of postural stability, gait parameters and symmetry. The aim of this study was to assess if VR training programme based on non-walking exercises improve gait parameters or change foot pressure distribution. Materials and methods 56 patients after THR were randomly assigned to an experimental group (30 people) and a control group (26 people). The control group (CG) attended a standard post-operative rehabilitation programme, while 12 sessions of VR training were added to the standard programme in the experimental group (EG). Each patient performed standing with eyes opened and gait test on Zebris FDM-T treadmill. We calculated spatio-temporal parameters, foot pressure distribution and CoP displacement. The results were considered significant for p <0.05. Results In the static tests, the force on the forefoot and the rearfoot of the operated limb increased in EG (p<0.05). The force on the non-operated-side foot decreased and the force of the foot on the operated side increased in CG (p <0.05). No differences were found in the CoP movement in both groups. Most of the gait parameters improved significantly in both groups (p<0.05). However, EG obtained superior results in comparison to CG (p <0.05) after rehabilitation with regard to step time in the operated limb, stride time, cadence and maximum force in the midfoot area in the operated limb. Conclusions 1. The significantly better gait performance parameters obtained in the experimental group indicate a better movement capacity in these patients. This suggests that using VR in motor re-education in patients after THR may enhance the effects of rehabilitation. 2. Further studies are necessary to assess the influence of VR training on pressure distribution both in static and dynamic tests.
