Background/purpose: Gait impairments in Parkinson disease (PD) contribute to decreased quality of life. This randomized controlled trial examined immediate- and longer-term effects of a single joint robotic exoskeleton device (EXOD), the Honda Walking Assist device, on gait.

Methods: Participants (n = 45) with PD (Hoehn and Yahr stages 1-3) were randomized to a robotic-assisted gait training (RAGT) group (n = 23) or control (CON) group (n = 22). The RAGT group was tested with and without the EXOD at baseline and then received supervised in-home and community training with the EXOD twice weekly for 8 weeks. The CON group received no interventions. Outcome measures included gait speed (primary), gait endurance (6-minute walk test), perceived ease of walking, and questionnaires and logs assessing performance of daily activities, freezing of gait, and daily activity levels.

Results: Forty participants completed the study. No significant immediate impact of EXOD usage on participants' gait measures was found. Differences in gait speed and secondary outcome measures postintervention were not significantly different between the RAGT and CON groups. Participants with greater disease severity (worse baseline motor scores) had greater improvements in stride length during unassisted walking after the intervention than those with lower severity (mean difference: 3.22, 95% confidence interval: 0.05-6.40; P = 0.04).

Discussion and conclusions: All RAGT participants could use the EXOD safely. The RAGT treatment used in this mostly low impairment population of people with PD may be ineffective and/or was insufficiently dosed to see a positive treatment effect. Our findings suggest that RAGT interventions in PD may be more effective in individuals with greater motor impairments.

Background and purpose: Individuals with multiple sclerosis (MS) frequently report low physical activity and psychosocial support due to concerns with transportation, time, finances, access to services, and lack of caregiver support. These barriers can be addressed by online group interventions; however, utility of such programs in individuals with MS has not been examined yet. The purpose of this retrospective study was, therefore, to ( a ) investigate the feasibility, safety, and outcomes of a virtual group exercise program in individuals with MS, and ( b ) explore the participant perceptions after the program.

Methods: Retrospective data from the medical records of 17 individuals with MS (mean [SD] age = 53.5 [12.3] years, body mass index = 28.2 [7.2]) who completed the virtual 13-week group exercise program, pre- and posttraining functional status questionnaires, and the end-of-program feedback were extracted. The exercise program included aerobic, resistance, balance, and flexibility training components recommended for people with MS. Feasibility, safety, outcomes, and participant perceptions were determined by adherence to the prescribed daily exercise dosage, number of adverse events, within-group differences in self-reported functional status, and thematic analysis of the participant feedback, respectively.

Results: Participants were adherent (79%), reported minimal adverse effects, and demonstrated significant changes ( P < 0.05) in functional status posttraining. Several themes on the perceived barriers, facilitators, and suggestions for improvement were identified.

Discussion and conclusions: A virtual 13-week group exercise program can be feasible, safe, effective, and well received by individuals with MS. Future research should investigate the dose-response effectiveness of telehealth and compare various telehealth models of exercise training using large randomized controlled trials.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1 available at: http://links.lww.com/JNPT/A434 , which demonstrates an overview of the study).

Background and purpose: Poor reactive steps may lead to falls in people with Parkinson disease (PwPD). However, whether reactive steps can be improved in PwPD at risk for falls or whether step training reduces falls remains unclear. This study aimed to determine whether 2 weeks of reactive step training result in (1) immediate and retained improvements in stepping and (2) fewer prospective falls in PwPD at fall risk.

Methods: Twenty-five PwPD (70.52 years ± 7.15; Hoehn & Yahr range 1-3) at risk for falls completed a multiple baseline, open-label, uncontrolled pre-/postintervention study. Stepping performance was assessed at 2 baseline assessments (B1 and B2) followed by a 2-week, 6-session training protocol. Stepping was assessed immediately (P1) and 2 months after training (P2). Primary outcomes were anterior-posterior margin of stability (MOS), step length, and step latency during backward stepping. Fall frequency was measured for 2 months before and after training.

Results: MOS during backward steps was significantly larger (better) after training ( P < 0.001, d = 0.83), and improvements were retained for 2 months ( P = 0.04, d = 0.66). Step length was not statistically significant different after training ( P = 0.13, d = 0.46) or at follow-up ( P = 0.08, d = 0.62), although effect sizes were medium and large, respectively. Step latency improved after initial exposure ( P = 0.01, d = 0.60) but not following training ( P = 0.43, d = 0.35). Twelve participants experienced fewer falls after training than before (10 = no change, 5 = increase; P = 0.12). Greater improvements in MOS were related to fewer falls ( P = 0.04).

Discussion and conclusions: Two weeks of reactive step training resulted in immediate and retained improvements in some reactive stepping outcomes in PwPD at risk for falls and may reduce fall risk. Reactive step training may be a viable approach to reduce falls in PwPD.
