Background: Dual tasking (DT) requires individuals to carry out two actions simultaneously, comparable to how the brain can perform a cognitive function while the body is in motion, which eventually enhances human balance. Objective: To examine and compare the impact of DT on the risk of falling (ROF) among Saudi female students enrolled in the literary and scientific faculties. Method: A cross-sectional design was used. 120 female students consented to this study after 150 were invited. Specialization led to the formation of the scientific (SG, 86) and literary (LG, 34) groups. All participants, aged 18 to 25, had a normal BMI and normal cognitive and balance skills. Using the Biodex balancing system, ROF during balance alone (no DT) and with DT (motor and two types of cognitive tasks) were assessed. ROF was compared within and between groups using paired and unpaired T-tests, respectively. Mann-Whitney compared the two groups throughout the DT. The level of significant was considered at P=0.05. Results: There was no significant difference in ROF in SG (P 0.05) between the performance with and without dual tasking, contrary, LG demonstrated a significant difference (P=0.05) for the same tests. In addition, the only time there was a significant difference between the two groups was when they performed DT. Conclusion: SG students are better capable than LG students in maintaining balance and resisting the ROF during DT. This study's findings may pave the way for improved interventions to reduce fall risk and improve balance during neurorehabilitation.

“…Neuroimaging can help us understand the pathological mechanisms underlying cognitive function in COPD patients. Traditionally, functional neuroimaging studies used functional magnetic resonance imaging (fMRI) to assess how different cognitive stimuli affect brain activity [31] . fNIRS is currently used to study gait neural pathways because it measures brain oxygen and allows movement [32] .…”

Background: Chronic obstructive pulmonary disease (COPD) is an irreversible disease characterised by persistent respiratory symptoms and decreased airflow. To improve the overall clinical picture of COPD, it is necessary to better understand all relevant comorbidities. Despite the fact that impairments in cognitive function are linked to higher mortality and disability rates in COPD, little is known about how these impairments can be improved. The purpose of this study is to investigate how head down and strong abdominal breathing and three other interventions affect oxygen utilization in COPD patients' dorsolateral prefrontal cortex (PFC) and general and specific cognitive domains, as well as to fill gaps in clinical evidence related to these interventions. Methods: We recruit 108 COPD patients in stable GOLD I-II stages at the Naval Anqing Hospital, using the blind method of evaluators and data analysts. There are four groups: head down and strong abdominal breathing training (Angle of inclination to 60°) , Ba Duan Jin, strong abdominal breathing training, and conventional treatment. Respiratory frequency is 35 breaths/min for 40 minutes three times a week for 12 weeks. The primary outcome is an assessment of general and four specific cognitive domains of function, as well as functional near infrared spectroscopy (fNIRS) recorded in the dorsolateral PFC of patients with normal or fast walking while performing motor or cognitive dual tasks containing oxygenated haemoglobin (oxy-Hb), deoxygenated haemoglobin (deoxy-Hb), and total oxygenated haemoglobin (total-Hb). Secondary outcomes include dyspnea symptoms, executive functions, anxiety and depressive symptoms, and balance. The outcomes will be measured one week before, six weeks after, and 12 weeks after. Discussion: The study may determine how effective head down and strong abdominal breathing exercises are for COPD patients with mild to moderate stable COPD. Also, it may help determine if it's more effective than other pulmonary rehabilitation treatments.

“…Specific molecules inside the neurons absorb the photons and change the rate of metabolic reactions within the cells, ultimately activating signaling pathways and transcription factors. [30][31][32] The primary molecular photoreceptor of red and near infrared light is cytochrome c oxidase, which is a key enzyme in the mitochondrial respiratory chain. PBM is a non-invasive technique that has been found to exert positive effects on cognitive function.…”

During the last decade, significant advances have been made in the application of using a near infrared LED light-emitting diode over the use of low-level laser light therapy for a wide range of healing and rehabilitation processes. Near infrared LED has been shown to represent a novel, non-invasive, and effective coadjutant therapeutic intervention for the treatment of numerous diseases. With the discovery of the use of gallium arsenate (red light), the near infrared light-emitting diode has shown to be an effective therapy in the use of wound, bone, and traumatic brain injuries. Specific applications include wound healing, dentistry, peripheral nerve injury, depression, neurological disease (including Parkinson’s Disease, depression, and dementia), aging cerebrovascular disease, and traumatic brain injury. Most recently, the application of infrared light on brain tumors (photodynamic therapy) has started to provide a positive result. More evidence-based research is required to support this growing coadjutant therapeutic intervention.
