NCT06482827

Brief Summary

The aim of this study is to determine whether a 4-week treatment of repetitive transcranial magnetic stimulation (rTMS) can alleviate the symptoms of neuropathy in individuals with diabetic neuropathy. The study will involve using questionnaires, nerve assessments, sensory tests, blood flow measurements, and blood tests to monitor any changes in symptoms after the rTMS intervention.

Outcome Measures

Primary Outcomes (4)

  • Modified Toronto Clinical Neuropathy Score

    Will be used to assess the presence and severity of diabetic neuropathy ('yes' or 'no')

    Immediately before intervention, immediately following intervention, 4 weeks after intervention

  • PROMIS-29 v2.0 Profile

    Using numerical rating (0 to 5) to assess seven health domains including physical function, anxiety, depression, fatigue, sleep disturbances, ability to participate in social roles and activities, and pain interference. Each category consists of 4 questions. Also uses a numerical rating to asses pain intensity (0-10).

    Immediately before intervention, immediately following intervention, 4 weeks after intervention

  • Patient Perceived Global Index of Change (PGIC)

    1-7 Likert Scale: Patients rate their change as "very much improved," "much improved," "minimally improved," "no change," "minimally worse," "much worse," or "very much worse

    Immediately following intervention, 4 weeks after intervention

  • Pain catastrophizing scale-EN-SF

    Will be used to assess the patients feeling and emotion related to their pain experience

    Immediately before intervention, immediately following intervention, 4 weeks after intervention

Secondary Outcomes (5)

  • Change in quantitative sensory testing

    Immediately before intervention, immediately following intervention, 4 weeks after intervention

  • Change in nerve conduction assessments

    Immediately before intervention, immediately following intervention

  • Change in blood flow

    Immediately before intervention, immediately following intervention

  • Changes in wound

    Immediately before intervention, immediately following intervention

  • Change in inflammation markers (IL-1B, IL-6, IL-10, TNF-α, TGF-β, CRP, SP, and BDNF)

    Immediately before intervention, immediately following intervention

Study Arms (2)

Group A (Sham)

SHAM COMPARATOR

Participants in group A will take part in 4 weeks of treatment with 5 sessions per week. Each session will involve sham repetitive transcranial magnetic stimulation (rTMS). Sham rTMS will be delivered at 10 Hz, 2004 pulses targeting the leg representation of the primary motor cortex. Participants will hear and experience the clicking but will not be provided with any stimulation. Sham rTMS will take approximately 11.5 minutes.

Device: Sham Repetitive transcranial magnetic stimulation

Group B (Active)

ACTIVE COMPARATOR

Participants in group B will take part in 4 weeks of treatment with 5 sessions per week. Each session will involve real repetitive transcranial magnetic stimulation (rTMS). rTMS will be delivered at 10 Hz, 2004 pulses targeting the leg representation of the primary motor cortex. rTMS will take approximately 11.5 minutes.

Device: Repetitive transcranial magnetic stimulation

Interventions

Sham repetitive transcranial magnetic stimulation (rTMS) is a non-invasive, non-painful procedure. The abductor pollicis brevis (APB) muscle of the left motor cortex will be targeted using neuronavigation software. During the sham, participants will hear and experience the clicking from the device but will not be provided with any stimulation. The delivery of sham rTMS requires \~ 11.5 minutes in total.

Group A (Sham)

Repetitive transcranial magnetic stimulation (rTMS) is a non-invasive, non-painful procedure used to relieve chronic pain and promote short-term changes. The abductor pollicis brevis (APB) muscle of the left motor cortex will be targeted using neuronavigation software. 2004 pulses will be delivered at 10 Hz stimulation. Stimulation will be delivered at 80% of the resting motor threshold obtained from the right APB muscle. The delivery of rTMS requires \~ 11.5 minutes in total.

Also known as: rTMS, Repetitive TMS
