Scrambler Therapy for Corticobasal Syndrome-Associated Pain
Johns Hopkins University
Summary
The goal of this pilot trial is to test whether scrambler therapy (ST) is an effective treatment for neuropathic pain in patients with corticobasal syndrome (CBS). The main question it aims to answer is: Will ST reduce pain scores by at least 33% at one month in this pilot trial, justifying further multi-center trials? Participants will: * be randomly assigned treatment from either transcutaneous electrical nerve stimulation (TENS) or ST for pain initially (eventually all patients will receive ST). * have superficial electrocardiogram (ECG) electrodes placed on the dermatomes involved with pain * obtain treatment lasting 30-40 minutes or until pain relief is obtained Researchers will compare patient's response to pain relief with TENS and ST to determine if ST is an effective treatment for central neuropathic pain.
Description
Pain can be a common non-motor complication of corticobasal syndrome (CBS), which is a rare debilitating parkinsonian disorder that lacks disease-modifying therapies. Pain in CBS typically increases in severity as the disease progresses and adversely impacts quality of life (including sleep and daily function). Scrambler therapy is a non-invasive electrical approach to neuromodulation that sends "nonpain" information along the existing nerve pathways to modify peripheral and central sensitization with success in randomized controlled trials treating such difficult neuropathies as spinal cord s…

Interventions
- DeviceScrambler therapy
Superficial electrocardiogram (ECG) electrodes are placed on the dermatomes involved with pain, above the area of pain itself. Each treatment lasts 30-40 minutes or until pain relief is obtained.
- DeviceTENS treatment
Superficial electrocardiogram (ECG) electrodes are placed on the dermatomes involved with pain, above the area of pain itself. Each treatment lasts 30-40 minutes or until pain relief is obtained.
