Mild traumatic brain injury (mTBI), is a developing public health problem. Evidence suggests that youth who suffer a mTBI experience worse outcomes than similar adults. However, the structure of long-term symptoms associated with mTBI is not well understood.

Research regarding noninvasive brain stimulation technologies for the treatment of mild traumatic brain injury (mTBI), posttraumatic stress disorder (PTSD), and mixed (mTBI/PTSD) trauma syndromes has been increasing exponentially. Technologies with the greatest potential thus far include repetitive transcranial magnetic stimulation (rTMS), transcranial direct current stimulation (tDCS), and cranial electrotherapy stimulation (CES). The nature and some of the controversies distinguishing mTBI, PTSD, and mTBI/PTSD are reviewed along with evidence for shared underlying mechanisms.

Pharmacologic and non-pharmacologic treatments for cancer-related fatigue (CRF) have produced mixed and often disappointing results. Treatment using the Flexyx Neurotherapy System (FNS), a novel variant of electroencephalograph biofeedback that involves minutely pulsed electromagnetic (EM) stimulation of brainwave functioning, was explored to determine utility for alleviating CRF in a 45-year-old woman who had debilitating fatigue with onset during chemotherapy for stage II infiltrating right breast cancer, who had been free of signs of disease for over five years, and who had been struggling to increase her activity level and engage in regular exercise without benefit. FNS was administered in 10 weekly sessions.

Previous report suggested the beneficial effects of an adaptation of the Flexyx Neurotherapy System (FNS) for the amelioration of mixed traumatic brain injury/post-traumatic stress symptoms in veterans of the Afghanistan and Iraq wars. As a novel variant of electroencephalograph biofeedback, FNS falls within the bioenergy domain of complementary and alternative medicine. Rather than learning voluntary control over the production/inhibition of brain wave patterns, FNS involves offsetting stimulation of brain wave activity by means of an external energy source, specifically, the conduction of electromagnetic energy stimulation via the connecting electroencephalograph cables.

Background: Chronic headache following traumatic brain injury (TBI) sustained in military service, while common, is highly challenging to treat with existing pharmacologic and non-pharmacologic interventions and may be complicated by co-morbid posttraumatic stress. Recently, a novel form of brainwave-based intervention known as the Flexyx Neurotherapy System (FNS) that involves minute pulses of electromagnetic energy stimulation of brainwave activity has been suggested as a means to address symptoms of TBI. This study reports on a clinical series of patients with chronic headache following service-connected TBI treated with FNS.

The Flexyx Neurotherapy System (FNS), a novel variant of EEG biofeedback, was adapted for intervention with seven treatment-refractory Afghanistan/Iraq war veterans, and brought about significant decreases in bothersome neurobehavioral and posttraumatic stress symptoms. FNS may help ameliorate mixed trauma spectrum syndromes.

Objective: To evaluate the efficacy of a novel variant of electroencephalograph biofeedback, the Low Energy Neurofeedback System (LENS), that utilizes minute pulses of electromagnetic stimulation to change brainwave activity for the amelioration of fibromyalgia (FM) symptoms.

Design: Randomized, double-blind, placebo-controlled clinical trial.

Setting: Tertiary referral academic medical center, outpatient.

Purpose: Patients who undergo orbital exenteration often experience social problems because of their facial disfigurement. The authors studied the interaction of cancer patients who had undergone orbital exenteration with family members and friends (primary groups) and with acquaintances and strangers (secondary groups) in small and large groups.

Methods: In-depth telephone interviews were conducted with 12 patients treated at a cancer center (7 men and 5 women aged 51-81 years) and 12 family members (8 spouses and 4 children or siblings).

The identification of adaptive and maladaptive coping strategies following traumatic events has been the subject of much scientific inquiry. The current study sought through meta-analysis to evaluate the relationship between the use of approach and avoidance strategies (both problem-focused and emotion/cognitive focused) following trauma and psychological distress. Thirty-nine studies of coping following two types of traumatic events (interpersonal violence and severe injury) were retained in the meta-analysis.

Background: Husbands of women with breast cancer may experience adjustment difficulties. We examined psychosocial predictors of husbands' adjustment to their wives' breast cancer 3 months following diagnosis.

Methods: Women (N = 45) with Stage I or II breast cancer who were 3 months postdiagnosis and their husbands completed measures of adjustment, coping, marital adjustment, and quality of life.

Married women's adjustment to breast cancer is positively influenced by their husbands' emotional support and by both spouses' active coping strategies. However, little is known about how women's adjustment is related to their husbands' perceptions of their psychosocial impairment. The current study examined the relationships among wives' coping strategies, the extent of congruence between wives' and husbands' perceptions of wives' adjustment, and wives' mood disturbance in 45 women with Stage I or II breast cancer and their husbands.

Invasive procedures have long held a place in the therapeutic armamentarium for the management of complex regional pain syndrome (CRPS). However, this has evolved considerably, particularly as research into the mechanisms of CRPS has called into question long-held presumptions about the key role of sympathetic dysfunction in the syndrome. This review summarizes some of the key information currently available about interventional treatments, including nerve blocks, spinal cord and peripheral nerve stimulation, chemical and surgical sympathectomies, and deep brain stimulation.

This study examined the relations between depression and demographic, pain-related, and work-related variables in 254 chronic pain patients. Regression analyses were conducted, initially by category (i.e.

The Beck Depression Inventory (BDI) is widely used to document the prevalence of depression in suffers of chronic pain and in research designs about this population. Williams and Richardson (1993) initially posed the question, "What does the BDI measure in chronic pain?". Results from their study found 3 independent constructs, which differed somewhat from those obtained in analyses with other non-pain subsamples.
