Introduction People living with multiple sclerosis (MS) often require rehabilitation to manage their symptom burden. Telerehabilitation offers improved access to treatment options by reducing travel time and cost. Our telerehabilitation program pairs training exercises simultaneously with transcranial direct current stimulation (tDCS), a non-invasive brain stimulation technique. In the current study, we characterized the benefits of our remotely supervised tDCS (RS-tDCS) at-home telerehabilitation protocol in an urban sample of MS participants. Methods Participants with MS were recruited to complete a telerehabilitation trial using tDCS paired with cognitive rehabilitation at-home using remote supervision (RS-tDCS). Participant time and travel costs for study visits to our clinic in midtown New York City were calculated. Results Forty-four patients with MS (aged 18 to 71) with mild to severe neurologic disability (Expanded Disability Status Scale score median = 3.5, range: 0.0 to 8.0) completed the survey. Round-trip clinic attendance required 2.3 ± 2.3 h and US $27.04 ± 38.13 for out-of-pocket expenses. Participants rated difficulty of clinic attendance as moderately to significantly difficult (2.5 ± 1.3). Severity of neurologic disability accounted for the greatest variance in difficulty attending clinic (30%, p < 0.001). RS-tDCS had 95% treatment compliance and 93% of participants reported satisfaction with the at-home treatment. Discussion Attending clinic is associated with significant costs for patients with neurologic disorders, even in urban settings. Rehabilitation can be delivered at home and supervised in real-time via videoconference.

Background: Cognitive impairment is a common feature of multiple sclerosis (MS). A semi-structured interview, including informant input, can characterize the experience of individuals living with MS and cognitive involvement.Objective: We administered the Cognitive Assessment Interview (CAI), a patient- and informant-based semi-structured interview, to characterize the experience of cognitive impairments in those living with MS.Methods: Trained raters administered the CAI to a sample of MS participants and their informants enrolled for a trial of cognitive remediation. Cognitive impairments on the CAI were characterized and compared to those captured by neuropsychological and self-report measures.Results: A total of n = 109 MS participants (mean age = 50.3 ± 12.2) and their available informants (n = 71) were interviewed. Participants reported experiencing processing speed (90/106, 85%), working memory (87/109, 80%), and learning and memory (79/109, 72%) problems most commonly. CAI-based ratings were moderately correlated with a self-report measure (Multiple Sclerosis Neuropsychological Screening Questionnaire, rs = 0.52, p &lt; 0.001) and only mildly correlated with objective neuropsychological measures specific to executive functions (rs = 0.21, p = 0.029). For those with informant interviews, ratings were overall consistent, suggesting that the CAI is valid even in cases in which an informant is unavailable and the interview is conducted with the patient alone (as is often the case in clinical and research settings).Conclusions: The CAI provides a semi-structured interview to characterize the experience of cognitive impairment in MS, with findings representing real-world functioning, adding valuable information to both self-report measures and neuropsychological assessment.
