People suffering from stroke often present with upper limb paralysis impacting their quality of life and ability to work. Motor impairments in the upper limb represent the most prevalent symptoms in stroke sufferers. There is a need to develop novel intervention strategies that can be used as stand-alone techniques or combined with current gold standard post-stroke rehabilitation procedures. There was reported evidence about the utility of rehabilitation protocols with motor imagery (MI) used either alone or in combination with physical therapy resulting in enhancement of post-stroke functional recovery of paralyzed limbs. Brain-Computer Interface (BCI) and EEG neurofeedback (NFB) training can be considered as novel technologies to be used in conjunction with MI and motor attempt (MA) to enable direct translation of EEG induced by imagery or attempted movement to arrange training that has potential to enhance functional motor recovery of upper limbs after stroke. There are reported several controlled trials and multiple cases series that have shown that stroke patients are able to learn modulation of their EEG sensorimotor rhythm in BCI mode to control external devices, including exoskeletons, prosthetics, and such interventions were shown promise in facilitation of recovery in stroke sufferers. A review of the literature suggests there has been significant progress in the development of new methods for post-stroke rehabilitation procedures.

This study retrospectively assessed EEG connectivity of participants in the International Collaborative ADHD Neurofeedback (ICAN) randomized controlled trial (7-10YO, N = 83) of theta/beta ratio neurofeedback (TBR-NFB). Using machine learning, it examined the relationship between inattention improvement on the Conners' Teacher and Parent Rating Scales (CTPRS) and specific baseline frequency connections within networks relevant to ADHD to find predictors of clinical improvement. Analyses were also performed considering specific comorbidities, slow cognitive tempo, ADHD presentation, pre-to-post network changes, and treatment group. Dysregulation in the ventral and dorsal attention networks, and delta and hibeta frequency bands throughout all networks were the strongest baseline connectivity predictors of clinical improvement on the CTPRS. The connectivity patterns predicting improvement differed significantly between active NFB and control. Other findings included predictors of improvements in EEG connectivity dysregulations, demographics, and connectivity patterns of comorbidity. Machine learning algorithms identified EEG features in connectivity, network, and frequency to assess when considering ADHD interventions.

As an initial step toward the development of a stress detection algorithm that functions well in clinical populations, we tested a series of stress-detection machine learning models on ambulatory electrocardiogram (ECG) and daily ecological momentary assessment (EMA) data collected from a sample of individuals in early recovery from alcohol use disorder (AUD). Forty-four individuals ages 18-65 in the first year of a current AUD recovery attempt wore an ECG monitor for 4 days, while concurrently completing 3-times-daily EMA of stress.

Target features were identified using unsupervised learning models (e.g., t-SNE, cluster analysis) and supervised learning models were tuned to optimize model performance. As a comparator, we also tested these models with laboratory-derived stress data from a sample of healthy young adults. Before accounting for individual characteristics, we achieved a modest accuracy of 63% in our clinical sample, which compared to 94% accuracy in the laboratory-derived healthy young adult sample.

This study aimed to evaluate the effects of music and medicine interventions on anxiety levels according to personality types in women with breast cancer receiving adjuvant chemotherapy. In a controlled, cross-sectional case-control study, 120 women were randomly assigned to two groups: an intervention group (music and medicine + chemotherapy) and a control group (chemotherapy only). The music playlist included classical, folk, and pop genres, and participants' anxiety levels were measured using the State-Trait Anxiety Inventory. Personality types were determined post-treatment using the Eysenck Personality Questionnaire - Revised Short Form. Serum C-reactive protein levels, blood pressure, and heart rate were also measured. Significant reductions were observed in anxiety levels, systolic blood pressure, heart rate, and serum C-reactive protein levels in the music intervention group compared to the control group. Neurotic individuals showed the most substantial improvement in anxiety, with reductions in systolic blood pressure and heart rate. Multivariate analysis revealed that both neurotic personality type and the music intervention were significant predictors of anxiety reduction. Music and medicine interventions provide notable benefits in reducing anxiety, particularly in neurotic individuals. Personalised music therapy based on personality types could enhance the quality of life for breast cancer patients undergoing chemotherapy.

This study aimed to explore the effects of resonance breathing on SKNA and HRV from the perspective of autonomic indices, evaluating its acute physiological impacts on a healthy population. A randomized crossover design was employed, recruiting 27 healthy university students (14 males, 13 females) as participants. The experimental protocol consisted of a 10-minute resting period, a 15-minute resonance breathing intervention, and a 5-minute post-intervention rest phase, during which SKNA and HRV were continuously monitored and evaluated. The results showed a significant increase in sympathetic nerve activity during the resonance breathing intervention phase, followed by notable reductions in both average sympathetic activity and burst-derived parameters post-intervention. In addition, HRV indicators, particularly RMSSD and RR interval, were markedly elevated after the intervention.

First, the necessity of an approach to client care that combines treatment modalities will be discussed. Then comes discussion of the history of combining modalities along with discussion of which combinations of treatments should be considered for different disorders. Attention-Deficit/Hyperactivity Disorder (ADHD), for example, requires more than one intervention because its neurological basis means it is appropriate for the brain-based intervention of neurofeedback and its comorbidities require other interventions, such as biofeedback for improved emotional regulation if there is anxiety and/or depression, and coaching in learning strategies (metacognition) to help with academic delays and/or learning disabilities. The triad of neurofeedback, biofeedback (especially heart rate variability training) and metacognitive strategies will produce improvements in most clients, regardless of their disorder. Additionally, it can also be used with athletes and executives to optimize performance. For complex cases, further interventions can be added. Medication might be needed as part of multi-modal management in ADHD or in depression or a seizure disorder. The dose can be tapered and, usually, eliminated, once the neurofeedback training produces a reduction in symptoms. Strategies can cover a wide range of approaches that are based on clients’ needs and presenting problems; for example, psychotherapy to deal with emotional issues.

A 15-minute baseline ECG recording pre-NSP, followed by a 15-minute ECG recording post-NSP for HRV analysis in recovery phase was attained using a digital polygraph. Blood pressure was noted before and at the end of ECG recording. Analysis of variability in HRV was done before and after the performance of NSP. Compared to baseline readings, a significant decrease in systolic blood pressure (SBP) and a significant increase in HRV parameters like SDNN (standard deviation of RR Intervals adjacent normal to normal intervals), and HF (high frequency), along with a significant decrease LF (low frequency), LF/HF (low/high frequency) ratio was observed post NSP practice. p < 0.05 was considered as significant.
