THE EFFECT OF A NOVEL REHABILITATION PROGRAM ON WALKING PERFORMANCE IN PERSONS WITH MULTIPLE SCLEROSIS

The purpose of this study was to compare if the addition of the NewGait™ device to traditional therapy in comparison to traditional therapy alone would be more effective at improving walking technique and walking performance in persons with multiple sclerosis. Eighteen patients with multiple sclerosis participated in this study. Pre- and post-testing assessed kinematic gait variables (speed, step length, step width, double limb support time), toe clearance height, ankle range of motion, balance confidence, rating of perceived exertion, and hip-ankle coordination. Participants completed an 8-week physical therapy protocol aimed to improve gait and balance with the experimental group wearing the NewGait™ device. Repeated measures mixed ANOVA revealed significant improvements over time for both groups, with increased walking speed, improved balance confidence, increase in bilateral step length, and a decrease in the percent of time spent in anti-phase and an ankle-driven coordination phase during swing for the unaffected limb (p \u3c 0.05). The experimental group experienced larger improvements in balance confidence (p \u3c 0.05), and coordination (p \u3c 0.05) when compared to the control group. The results of the current study indicate that the use of the NewGait™ during rehabilitation is effective at improving balance confidence lower limb coordination

THE EFFECT OF A NOVEL REHABILITATION PROGRAM ON WALKING PERFORMANCE IN PERSONS WITH MULTIPLE SCLEROSIS

The current study examined the effects of the NewGait™ device on walking performance in persons with multiple sclerosis (MS). Eight MS patients participated in this study. Pre- and post-testing assessed kinematic gait variables (step width, length, and speed), ankle range of motion, and rating of perceived exertion (RPE). Participants completed an 8-week physical therapy (PT) protocol aimed to improve gait and balance, with the experimental group wearing the NewGait™ device. Repeated measures mixed ANOVA showed no main effects between the gait variables or between groups. Post-hoc paired t-tests indicated that the NewGait™ device elicited meaningful change in left and right step length and speed. The NewGait™ device may be a promising rehabilitation device to help induce positive walking performance changes in persons with MS

CHANGES IN GAIT AND COORDINATION VARIABILITY IN PERSONS WITH MULTIPLE SCLEROSIS FOLLOWING A REHABILITATION PROGRAM

This study investigated changes in gait and coordination variability in persons with Multiple Sclerosis (MS) after an 8-week rehabilitation intervention. Data for eight participants (Control: 4, Intervention: 4) were analyzed via Cortex Motion Analysis software and Visual 3D to calculate knee and ankle joint angles as well as discrete spatiotemporal parameters. The knee and ankle joint angles were further analyzed using a vector coding technique to quantify coordination between these joints and how they produce a functional gait pattern. No significant changes in gait or coordination variability were found after rehabilitation, but some meaningful changes with large and moderate effect sizes were present. This study demonstrated a comprehensive overview of the relationship between process and outcome variability in a clinical population

THE EFFECT OF A NOVEL REHABILITATION DEVICE ON MUSCLE ACTIVATION DURING GAIT IN PERSONS WITH MULTIPLE SCLEROSIS

This study examined the acute effect of a novel rehabilitation device, NewGait™, on muscle activation in persons with Multiple Sclerosis. Through electromyography, muscle activation of the vastus medialis (VM), gastrocnemius lateralis (GL) and tibialis anterior (TA) was measured in seventeen patients (n=17). Three trials were conducted in each condition: a 10-meter control walk and 10-meter NewGait™ walk. Results showed a non-significant change in muscle activity with moderate effect sizes in the right VM (increase of 39.72% MVC, p=0.082, d=0.626) and right TA (decrease of 12.71% MVC, p=0.069, d=0.427). In general, no change in muscle activation was noted when wearing the NewGait™ device. Future research should include a larger sample size and differentiation between the stance phases to accurately measure the outcomes of the NewGait™ device on muscle activation

THE USE OF A LOWER-LIMB PROSTHETIC DEVICE TO IMPROVE PERFORMANCE FACTORS IN ELITE PARACANOE

The current study examined how a lower-limb prosthesis affected paracanoe performance factors. One paracanoe athlete completed two, 30 second tethered sprints with and without the use of a custom prosthesis. Kinematic and kinetic performance variables were compared. When the prosthesis was worn, a significant increase in propulsion impulse was observed on the right side (50 Ns to 61 Ns), which may have been due to enhanced contact between the residual limb and the kayak. Stroke rate symmetry index became significantly more symmetrical while wearing the prosthesis (0.27 to 0.01); perhaps due to a more upright trunk position, decreasing variability in center of gravity movement. In conclusion, based on the results, the addition of a prosthesis for the paracanoe athlete in the present study had a positive effect on performance factors
