Scrambler Therapy for Corticobasal Syndrome-Associated Pain
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.

(Scale 0-10; 0= No pain, 10= Pain as bad as you can imagine)
