LENS Research

Introduction to LENS:

D. Corydon Hammond PhD

“This volume introduces the reader to a unique, innovative neurofeedback/neurotherapy technology called the Low Energy Neurofeedback System (LENS). The LENS treatment method has gradually evolved over the past 16 years, primarily through the innovations of Len Ochs, PhD. In this volume you will read about the LENS, its historical evolution, and its application in the treatment of a variety of diagnostic problems.”

The LENS: A Clinical Outcomes Study on One Hundred Patients at Stone Mountain Center, New York

Stephen Larsen, PhD; Kristen Harrington, MA; Susan Hicks, BA

“The Low Energy Neurofeedback System (LENS) developed by Dr. Len Ochs (2006a) uses feedback in the form of a radio frequency carrier wave, administered at a positive offset frequency from the person’s own dominant EEG frequency. Although it is an unusual biofeedback procedure, the feedback being invisible and the subject passive, clinical evidence supports the efficacy of the LENS across a spectrum of conditions. Published research studies (Schoenberger, Shifflet, Esty, Ochs, & Matheis, 2001; Donaldson, Sella, & Mueller, 1998; Mueller, Donaldson, Nelson, & Layman, 2001) have shown the effectiveness of the LENS method with traumatic brain injury (TBI) and with fibromyalgia…The study hypotheses were that the LENS treatment would be effective in reducing both systematic symptom ratings and measurements of EEG amplitudes, and that the therapeutic effect would produce the most rapid improvements in early sessions of treatment.”

Specific Conditions:

Anger Treatment

D. Corydon Hammond PhD

“Significant improvements were reported in a variety of symptoms and changes in anger were evaluated with the State-Trait Anger Expression Inventory–2. Although the case reports are uncontrolled and represent only very preliminary evidence, the results support the potential of LENS neurofeedback to produce significant improvements in anger control, which has implications with many diagnoses, including traumatic brain injury, juvenile and adult correctional populations, and domestic violence.”

ADHD

…we conclude that neurofeedback treatment for ADHD can be considered “Efficacious and Specific” (Level 5) with a large effect sizes for inattention and impulsivity and a medium ES for hyperactivity.

…main studies demonstrated, where reported, an overall ADHD mean effect size of d = 0.69, a medium effect.

Cognitive Performance

The results suggested that PAF NF improved cognitive processing speed and executive function.

Repeated-measures revealed strongly significant improvements (P < .001) on all 4 cognitive measures (perceived cognitive impairment, comments from others, perceived cognitive abilities, and impact on quality of life), the fatigue scale, and the 4 psychological scales (somatization, depression, anxiety and global severity index) as well as on 3 of 8 sleep scales (quality, daytime dysfunction, and global).

Migraines

Clinical benefit to patients suffering from recurrent migraine headaches and who opted to stop medication and take a neurofeedback treatment series.

 Feedback was accompanied by a significant reduction of cortical excitability.  This was probably responsible for the clinical efficacy of the training; a significant reduction of days with migraine and other headache parameters was observed.

PTSD Treatment

“Military doctors struggling to treat post-traumatic stress disorder are quietly adding a new tool to their arsenal: A controversial brain-wave therapy they say can heal troubled veterans and even send once-broken troops back into combat…Dr. Jerry Wesch, the officer in charge of the PTSD recovery program at Fort Hood — where Roberts underwent treatment — was so astounded by neurofeedback’s results that he personally spent several thousand dollars to order neurofeedback equipment for the base.”
