Abstract: BACKGROUND: : Bowel symptoms are common in patients with multiple sclerosis, but current treatment is empirical. OBJECTIVE: : This study aimed to identify effect of biofeedback on bowel symptoms, mood, and anorectal physiology in patients with multiple sclerosis. DESIGN: : This was a prospective observational study: the amount of change between pre- and posttreatment values of outcome measures was compared and analyzed. Responders were considered to be patients who demonstrated an improvement greater than or equal to the 25th percentile of the change in bowel score. Comparison between responders and nonresponders was performed. SETTINGS: : This investigation was conducted at a neurogastroenterology clinic, tertiary referrals center. PATIENTS: : Thirty-nine patients with multiple sclerosis and constipation and/or fecal incontinence were included in the study. INTERVENTION: : Patients were given bowel biofeedback therapy. MAIN OUTCOME MEASURES: : The primary outcome measures were the Wexner Constipation and Wexner Incontinence scores. The secondary outcome measures were hospital anxiety and depression scores and anorectal physiology parameters. RESULTS: : Data are reported as median and interquartile ranges. After biofeedback there was significant improvement in Wexner Constipation (12 (5-19) pretreatment vs 8 (4-14) posttreatment, P = .001), Wexner Incontinence (12 (3-15) pretreatment vs 4 (2-10) posttreatment, P<.001) and hospital depression scores (7 (3-11) pretreatment vs 5 (3-10) posttreatment, P = .015). The 5-second endurance squeeze pressure was also improved (21 (11-54) mmHg pretreatment vs 43 (26-59) mmHg posttreatment, P = .001). Posttreatment change of Wexner Constipation was -2(-5/0), and of Wexner Incontinence was -3(-9/0) ("-" indicates improvement). Therefore, those patients who had a reduction of at least 5 points in the Wexner Constipation score and/or of at least 9 points in the Wexner Incontinence score were considered responders (18 patients, 46%). They showed a greater improvement of only 5-second endurance squeeze pressure (23.5 (7.5/32.75) mmHg responders vs 4 (-6/20) mmHg nonresponders, P = .008); no difference was observed in the comparison of baseline variables with nonresponders. Significant negative relationship existed between the change in the Wexner Constipation score (-2 (-5/0)) and the pretreatment Wexner Constipation score (12 (5/19),β = -0.463, P<.001), and the change in the Wexner Incontinence score (-3 (-9/0)) with the pretreatment Wexner Incontinence score (12 (3/15),β = -0.590, P<.001). So, the higher the initial bowel symptom score, the greater the improvement. LIMITATIONS: : This study was limited by the lack of a control group. CONCLUSIONS: : Biofeedback improves bowel symptoms, depression, and 5-second endurance squeeze pressure in patients with multiple sclerosis. Article Published Date : Sep 01, 2011

Non-pharmacological management of migraine during pregnancy.

Abstract Title: Non-pharmacological management of migraine during pregnancy. Abstract Source: Neurol Sci. 2010 Jun;31 Suppl 1:S63-5. PMID: 20464586 Abstract Author(s): Gisella Airola, Gianni Allais, Ilaria Castagnoli Gabellari, Sara Rolando, Ornella Mana, Chiara Benedetto Article Affiliation: Department of Gynecology and Obstetrics, Women's Headache Center, University of Turin, Via Ventimiglia 3, 10126, Turin, Italy. Abstract: Migrainous women note a significant improvement in their headaches during pregnancy. However, persistent or residual attacks need to be treated, keeping in mind that many drugs have potential dangerous effects on embryo and foetus. It is evident, therefore, that hygiene and behaviour measures capable of ensuring the best possible well-being (regular meals and balanced diet, restriction of alcohol and smoking, regular sleeping pattern, moderate physical exercise and relaxation) are advisable during pregnancy. Among non-pharmacological migraine prophylaxis only relaxation techniques, in particular biofeedback, and acupuncture have accumulated sufficient evidence in support of their efficacy and safety. Some vitamins and dietary supplements have been proposed: the prophylactic properties of magnesium, riboflavin and coenzyme Q10 are probably low, but their lack of severe adverse effects makes them good treatment options.

Correction of posture disorders and scoliosis in schoolchildren using functional biofeedback

Abstract Title: [Correction of posture disorders and scoliosis in schoolchildren using functional biofeedback]. Abstract Source: Rheumatol Int. 2010 Apr 14. Epub 2010 Apr 14. PMID: 2175121 Abstract Author(s): O V Bogdanov, N I Nikolaeva, E L Mikhaĭlenok Abstract: A novel technique is offered for correction of postural defects and early manifestations of scoliosis in schoolchildren using methods of functional biofeedback training. The technique allowed the patient to use the biofeedback signals informing on the degree of asymmetry in bioelectric activity of paravertebral muscles in static active straightening of the vertebral column. The data revealed a steady decrease in asymmetric activity indices in muscles erecting the column. This provided a physiological basis for a high clinical efficiency of the technique.

Abstract: OBJECTIVE: Chronic pain conditions such as phantom limb pain and complex regional pain syndrome are difficult to treat, and traditional pharmacological treatment and invasive neural block are not always effective. Plasticity in the central nervous system occurs in these conditions and may be associated with pain. Mirror visual feedback therapy aims to restore normal cortical organization and is applied in the treatment of chronic pain conditions. However, not all patients benefit from this treatment. Virtual reality technology is increasingly attracting attention for medical application, including as an analgesic modality. An advanced mirror visual feedback system with virtual reality technology may have increased analgesic efficacy and benefit a wider patient population. In this preliminary work, we developed a virtual reality mirror visual feedback system and applied it to the treatment of complex regional pain syndrome. DESIGN: A small open-label case series. Five patients with complex regional pain syndrome received virtual reality mirror visual feedback therapy once a week for five to eight sessions on an outpatient basis. Patients were monitored for continued medication use and pain intensity. RESULTS: Four of the five patients showed>50% reduction in pain intensity. Two of these patients ended their visits to our pain clinic after five sessions. CONCLUSION: Our results indicate that virtual reality mirror visual feedback therapy is a promising alternative treatment for complex regional pain syndrome. Further studies are necessary before concluding that analgesia provided from virtual reality mirror visual feedback therapy is the result of reversing maladaptive changes in pain perception.

The relative efficacy of connectivity guided and symptom based EEG biofeedback for autistic disorders.

Abstract Title: The relative efficacy of connectivity guided and symptom based EEG biofeedback for autistic disorders. Abstract Source: Appl Psychophysiol Biofeedback. 2010 Mar;35(1):13-23. Epub 2009 Aug 1. PMID: 19649702 Abstract Author(s): Robert Coben, Thomas E Myers Abstract: Autism is a neurodevelopmental disorder characterized by deficits in communication, social interaction, and a limited range of interests with repetitive stereotypical behavior. Various abnormalities have been documented in the brains of individuals with autism, both anatomically and functionally. The connectivity theory of autism is a recently developed theory of the neurobiological cause of autisic symptoms. Different patterns of hyper- and hypo-connectivity have been identified with the use of quantitative electroencephalogray (QEEG), which may be amenable to neurofeedback. In this study, we compared the results of two published controlled studies examining the efficacy of neurofeedback in the treatment of autism. Specifically, we examined whether a symptom based approach or an assessment/connectivity guided based approach was more effective. Although both methods demonstrated significant improvement in symptoms of autism, connectivity guided neurofeedback demonstrated greater reduction on various subscales of the Autism Treatment Evaluation Checklist (ATEC). Furthermore, when individuals were matched for severity of symptoms, the amount of change per session was significantly higher in the Coben and Padolsky (J Neurother 11:5-23, 2007) study for all five measures of the ATEC. Our findings suggest that an approach guided by QEEG based connectivity assessment may be more efficacious in the treatment of autism. This permits the targeting and amelioration of abnormal connectivity patterns in the brains of people who are autistic. Article Published Date : Mar 01, 2010

MEG Insight into the Spectral Dynamics Underlying Steady Isometric Muscle Contraction.

Related Articles MEG Insight into the Spectral Dynamics Underlying Steady Isometric Muscle Contraction. J Neurosci. 2017 Oct 25;37(43):10421-10437 Authors: Bourguignon M, Piitulainen H, Smeds E, Zhou G, Jousmäki V, Hari R Abstract To gain fundamental knowledge on how the brain controls motor actions, we studied in detail the interplay between MEG signals from the primary sensorimotor (SM1) cortex and the contraction force of 17 healthy adult humans (7 females, 10 males). SM1 activity was coherent at ∼20 Hz with surface electromyogram (as already extensively reported) but also with contraction force. In both cases, the effective coupling was dominant in the efferent direction. Across subjects, the level of ∼20 Hz coherence between cortex and periphery positively correlated with the "burstiness" of ∼20 Hz SM1 (Pearson r ≈ 0.65) and peripheral fluctuations (r ≈ 0.9). Thus, ∼20 Hz coherence between cortex and periphery is tightly linked to the presence of ∼20 Hz bursts in SM1 and peripheral activity. However, the very high correlation with peripheral fluctuations suggests that the periphery is the limiting factor. At frequencies <3 Hz, both SM1 signals and ∼20 Hz SM1 envelope were coherent with both force and its absolute change rate. The effective coupling dominated in the efferent direction between (1) force and the ∼20 Hz SM1 envelope and (2) the absolute change rate of the force and SM1 signals. Together, our data favor the view that ∼20 Hz coherence between cortex and periphery during isometric contraction builds on the presence of ∼20 Hz SM1 oscillations and needs not rely on feedback from the periphery. They also suggest that effective cortical proprioceptive processing operates at <3 Hz frequencies, even during steady isometric contractions.SIGNIFICANCE STATEMENT Accurate motor actions are made possible by continuous communication between the cortex and spinal motoneurons, but the neurophysiological basis of this communication is poorly understood. Using MEG recordings in humans maintaining steady isometric muscle contractions, we found evidence that the cortex sends population-level motor commands that tend to structure according to the ∼20 Hz sensorimotor rhythm, and that it dynamically adapts these commands based on the <3 Hz fluctuations of proprioceptive feedback. To our knowledge, this is the first report to give a comprehensive account of how the human brain dynamically handles the flow of proprioceptive information and converts it into appropriate motor command to keep the contraction force steady.
