Neurofeedback in Decreasing Acute Radiotherapy-Induced Pain in Patients With Head and Neck Cancer

The qEEG normative database is grouped by age and contains a sufficiently large sample size with means and standard deviations of the EEG time series and/or frequency domain analysis computed for each age group.

The LORETA software package is used to perform the statistical analyses. The methodology used is non-parametric. It is based on estimating, via randomization, the empirical probability distribution for the max-statistic (e.g. the maximum of a t or an F statistic), under the null hypothesis. This methodology corrects for multiple testing (i.e., for the collection of tests performed for all electrodes and/or voxels, and for all time samples and/or discrete frequencies. Due to the non-parametric nature of the method, its validity need not rely on any assumption of Gaussianity.

is a validated, widely used, self-administered questionnaire to assess severity of pain and impact of pain on daily functioning among patients (Cleeland, 2006; Cleeland, 1991; Tan, 2004). The Brief Pain Inventory (Short form) Scale 0-10 (No Pain 0-10 As Bad as you can imagine ).

is a measure generally used in chronic pain conditions used to measure the patient perception of their pain experience. The MPI has 4 subscales that assess pain intensity, emotional distress, cognitive and functional adaptation, and social support. It is used to assess overall adjustment of pain and outcomes of treatment interventions. Although it is generally used for chronic pain patients, the MPI has also been used in studies with patients who have acute pain (Edwards, Et al., 2006; Montes Doncel, et al., 2001).

will also be administered with the MPI as a measure of validity. The inclusion of these measures allows us to assess perceived relational support in general (SPS) and in specific relation to their pain (MPI). For the patients who consent to their spouses/caregivers participating in the optional survey, the spouses/caregivers will be given the SPS at the same timepoints as the patient.

Cancer-related symptoms will be assessed using the validated MDASI-HN. The MDASI measures, on a numeric rating scale of 0-10, both the severity of symptoms and the interference symptoms cause in patients" daily activities. The 13 core MDASI symptom items are based on extensive evaluation of symptoms common to cancer and cancer treatment. The MDASI-HN includes 9 head and neck-specific items. The instrument was validated in a cohort of more than 200 patients and found to be highly reliable (Rosenthal, Mendoza, & Chambers, 2007).

A visual analog scale to assess pain (0-10 scale) will be used before and after each training session to determine if change in brain function is meaningful clinically.

A visual analog scale to assess mouth sores (0-10 scale) will be used before each training session to determine patient perception of interference with quality of life due to mucositis. A visual analog scale to assess patient comfort (0-10 scale) will be used before and after each training session to determine patient perception of overall comfort.

All medications prescribed and used by the patients for pain or other medical conditions will be collected during the time they are participating in the study. We will use descriptive statistics to summarize pain medication use over the course of the study and radiation dose. We will tabulate adverse events by grade and relationship to therapy.
