The purpose of this research is to better understand how deep brain stimulation settings can affect the electrical activity in the brain and the frequency of seizures. There are a number of different ways in which the deep brain stimulation electrodes can be programmed to stimulate the brain. This research study uses the implanted battery in the chest to record electrical activity from the brain at different stimulation settings. We then use this electrical activity to determine stimulation settings that are “personalized” to your brain.

There is no consensus on the radiation dose required to relieve the pain from bone lesions from multiple myeloma. Usually, patients receive between 10 and 12 radiation treatments to achieve pain relief. But a shorter course of radiotherapy may be more effective. This study will evaluate whether pain relief can be achieved using only 1 or 2 radiation treatments, which will be delivered to a painful bone lesion. Your study doctor will decide whether you receive 1 or 2 treatments. The total amount of radiation you will receive will be the same whether it is done in one or two treatment sessions.
