This study investigates whether transcranial electrical stimulation (tES) delivered during structured reading instruction affects reading proficiency in children with developmental dyslexia and related reading disabilities. Children aged 7 to 17 who have been identified as having dyslexia or reading difficulties are randomly assigned in equal numbers to receive either active stimulation or sham (placebo) stimulation while completing structured reading instruction. Participants wear a non-invasive transcranial electrical stimulation headset that delivers a low-level electrical current through electrodes resting on the scalp. Sessions typically last 20 to 30 minutes and may take place at home or in person at a participating site. A trained adult is present and supervising for every session. Reading proficiency is measured with standardized assessments before and after the intervention period. A follow-up assessment may be conducted up to 12 months after the intervention ends. The device used in this study is investigational and has not been approved or cleared by the U.S. Food and Drug Administration.
Regulatory pathway: because developmental dyslexia and related learning disabilities are considered diseases by the U.S. Food and Drug Administration for purposes of device classification, the investigational use of tES in this study falls within FDA jurisdiction. The study is conducted under the abbreviated investigational device exemption pathway on the basis of an IRB non-significant risk determination under 21 CFR 812.2(b). No IDE number is issued by FDA for a study conducted under this pathway. The study is a prospective, randomized, double-blind, sham-controlled investigation. Participa…
Inclusion Criteria: * Children aged 7 to 17 years inclusive * Diagnosed with developmental dyslexia or related reading disability, OR exhibiting reading difficulties consistent with developmental dyslexia (for example, performing below the participant's expected grade level on a standardized reading assessment), as identified by the participant's educator, reading practitioner, caregiver, or clinician. A formal clinical diagnosis is not required for enrollment. * Concurrently receiving or able to receive structured reading instruction during the intervention period * Parent or legal guardian…
Non-invasive transcranial electrical stimulation delivered by a scalp-mounted headset within the LOTES-2023 limited-output envelope, paired with structured reading instruction. Pediatric declared range 0 to 2 mA average absolute current, maximum current density 2 mA/cm2 at the electrode contact area, maximum session duration 60 minutes subject to a 6000 mC per-session total charge limit, and a maximum of 30 total sessions per participant. Electrodes are placed in standard cephalic or extracephalic montages targeting cortical regions implicated in reading networks. The device is investigational and is not approved or cleared by the U.S. FDA.
Sham stimulation delivered by the same scalp-mounted headset, providing the initial cutaneous sensory experience of stimulation onset without sustained current delivery, paired with the same structured reading instruction. The specific validated sham approach is selected per cohort and documented in the corresponding cohort plan.
