Scrambler Therapy in Treating Pain and Peripheral Neuropathy in Patients Previously Treated With Chemotherapy - Full Text View

Purpose

This pilot clinical trial studies scrambler therapy in treating pain and peripheral neuropathy in patients previously treated with chemotherapy. Scrambler therapy may help relieve pain from peripheral neuropathy caused by chemotherapy

Primary Outcome Measures:

Change in pain on a 0-10 numerical rating scale. [ Time Frame: 3 years ] [ Designated as safety issue: Yes ]

Secondary Outcome Measures:

Changes in neurologic function will be done by Neurometer Current Perception Threshold (CPT) testing and with a Rydel-Seiffer graduated tuning fork. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
Patients will also undergo neurologic function testing. This will be done in an exploratory measure to try to correlate changes in the patient reported outcome instrument data with changes in the different measures of neurologic function. The two measures will be Neurometer Current Perception Threshold (CPT) Testing and testing with a Rydel-Seiffer graduated tuning fork.

Detailed Description:

OBJECTIVES:

I. To record the types of patients that we treat, along with the reported efficacy and potential toxicity associated with scrambler therapy.

II. To get experience with patient reported outcome measurement tools that we use in this trial, including a report of analgesic use.

OUTLINE: Patients undergo scrambler therapy for 30 minutes daily for up to 10 consecutive days. Treatment continues in the absence of unacceptable toxicity. After completion of study treatment, patients are followed up for 10 weeks.

III. To explore neurologic testing changes in patients receiving scrambler therapy.

Eligibility

Criteria

Inclusion Criteria:

Pain or symptoms of neuropathy or pain of >= 1 month (30 days) duration for which the patient wants intervention
Participants have to relate that tingling or pain was at least a four out of ten problem during the prior week, on a 0-10 scale where zero was no problem and ten was the worst possible problem and expected to have tingling or pain of at least 4/10 at the time of the first treatment
Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) = 0, 1, or 2
Life expectancy >= 3 months (90 days)
Case review by the study chair, or designate, as a case where treatment should be tried.
Ability to complete questionnaire(s) by themselves or with assistance - Ability to provide informed written consent

Exclusion Criteria:

Pregnant women
Patients with implantable drug delivery systems, e.g. Medtronic Synchromed
Patients with heart stents or metal implants such as pacemakers, automatic defibrillators, aneurysm clips, vena cava clips and skull plates; (metal implants for orthopedic repair, e.g. pins, clips, plates, cages, joint replacements are allowed as are central venous access devices)
Patients with a history of myocardial infarction or ischemic heart disease within the past six months
Patients with history of epilepsy, brain damage, use of anti-convulsants for seizure prevention, concurrently using ketamine, symptomatic brain metastases; Note: anti-convulsant use is allowed for neuropathy and heart failure (HF) if on a stable dose
Skin conditions such as open sores that would prevent proper application of the electrodes
Other medical or other condition(s) that in the opinion of the investigators might compromise the objectives of the study
Currently on gabapentin or pregabalin Note: (because of data that support that patients don't do as well when on gabapentin or pregabalin, all patients on these medications will be weaned off of them prior to study initiation. The study team will provide instructions on how to do this).
