Pilot Study of Transcranial Direct Current Stimulation (tDCS)

28. april 2020 opdateret af: NYU Langone Health
This study will test the tolerability and preliminary efficacy of transcranial direct current stimulation (tDCS) combined with a cognitive training program, remotely-delivered using a telemedicine protocol in 60 adults with multiple sclerosis (MS). The study will evaluate the efficacy of tDCS to evaluate two of the most debilitating symptoms of MS: cognitive impairment and fatigue.

Detaljeret beskrivelse

Transcranial direct current stimulation (tDCS) has been demonstrated to:

  1. successfully treat fatigue in adults with MS, and
  2. improve learning ability and other aspects of cognitive functioning in healthy controls and in participants with a range of medical disorders.

Cognitive impairment in MS remains a major treatment challenge and a trial of tDCS combined with a cognitive training program to treat MS-related cognitive impairment is warranted. However, one barrier for the study of tDCS has been the need for the participant to travel to the study site for each tDCS administration. To address this issue, the biomedical company Soterix, has recently designed a remote-delivery tDCS device designed for use in clinical trials. Therefore, the primary goal of this study is to establish a protocol for remotely-supervised in-home tDCS delivery for studies with MS participants. Established safety and feasibility of remotely-supervised tDCS delivery will facilitate the next steps of larger controlled trials, in both MS as well as other conditions, to determine efficacy and appropriate real-world use.

Beskrivelse

Inclusion Criteria:

  • Ages 18-70
  • Definite MS diagnosis, all subtypes [95]
  • MS-related changes in cognitive functioning
  • A score of 6.5 or lesson the Expanded
  • Disability Status Scale (EDSS) OR more than 6.5 with proxy
  • Has stable and continuous access to internet service at home compatible with the study laptop (Wi-Fi or ethernet cable)
  • Adequate internet capacity for remote monitoring, as tested by http://www.speedtest.net/)

Våben og indgreb

Deltagergruppe / Arm
Intervention / Behandling
Aktiv komparator: Transcranial Direct Current Stimulation (tDCS)
Enhed: Transcranial Direct Current Stimulation (tDCS)
tDCS is a therapeutic development that utilizes low amplitude direct currents to induce changes in cortical excitability. tDCS is expected to produce neuronal polarization of less than one mV (millivolt) 9. tDCS produces relatively diffuse current flow, as demonstrated by imaging studies and computational models
Andre navne:
  • Soterix 1x1 tDCS mini-CT
Adfærdsmæssigt: Cognitive Training Program
Sham-komparator: Sham Transcranial Direct Current Stimulation (tDCS)
Adfærdsmæssigt: Cognitive Training Program
Enhed: Sham Transcranial Direct Current Stimulation
During a sham session, the device is programmed to ramp up to the desired intensity (target 2.0 mA) and ramp down for the initial 60 seconds, with no current delivery during the session, and then again at the end of the session. These brief periods of stimulation serve to mimic the effects of a true stimulation session.

Foranstaltningsbeskrivelse
Tidsramme
The Number of Participants Completing at Least 80% of the Targeted Sessions.
Tidsramme: Four Weeks
80% is equivalent to n=16 of the targeted 20 transcranial direct current stimulation (tDCS) or sham tDCS sessions.
Four Weeks
Change in Total Score of the Brief International Assessment of Cognition in MS (BICAMS)
Tidsramme: Baseline, Four Weeks

BICAMS comprises two tests, the Symbol Digit Modalities Test (SDMT) and the Brief Visuospatial Memory Test-Revised (BVMT-R).

Scoring for SDMT involves summing the number of correct substitutions within the 90 second interval (max = 110. The higher the score, the better).

Visual/spatial memory is assessed in BICAMS using the BVMTR. In this test, six abstract designs are presented for 10 sec. The display is removed from view and patients render the stimuli via pencil on paper manual responses. Each design receives from 0 to 2 points representing accuracy and location. Thus, scores range from 0 to 12 (the higher the score, the better).

The total score range for BICAMS is 0-122. The higher the score, the better.

Tidsramme
Change in Score on Modified Fatigue Impact Scale (MFIS)
Tidsramme: Baseline, 4 Weeks
MFIS consists of 21 statements. The number that best indicates how often fatigue has affected the participant in the manner described during the past 4 weeks is circled. Answer choices include: 0 - never, 1 - rarely, 2 - sometimes, 3 - often, 4 - almost always. The total score ranges from 0 to 84. The higher the number, the more frequently fatigue impacted the participant during the past 4 weeks.
Baseline, 4 Weeks
Change in Score of CogState Brief Battery (CBB)
Tidsramme: Baseline, 4 Week
CBB is a brief, computer-administered cognitive test battery that requires approximately 10 minutes for administration. If the CBB score falls between -10 to +10, it is considered normal. CogState scoring is such that 0 could be considered as performing in the average range for that subtest compared to people of similar age. A negative score means that the performance was lower than average, and a positive score means the performance was higher than average. Higher positive scores (for instance 0.2 becoming 0.5) may indicate slightly better performance and higher negative scores (for instance, -0.4 becoming -0.8) may indicate slightly worsening performance.
