Effect of Dynamic Neuromuscular Stabilization on Balance, Trunk Function, Falling, and Spasticity in People With Multiple Sclerosis: A Randomized Controlled Trial.

OBJECTIVE: To compare the effects of core stabilization (CS) and dynamic neuromuscular stabilization (DNS) on balance, trunk function, mobility, falling, and spasticity, in people with multiple sclerosis (PWMS). DESIGN: Two-group randomized controlled trial. SETTING: General community and referral center. PARTICIPANTS: A total of 64 PWMS, between 30 and 50 years old, and an expanded disability status scale between 2 and 5, participated in this study (N=64). INTERVENTIONS: Participants were randomly assigned to CS (n=32) and DNS (n=32) groups. Both groups received a total of 15 sessions of CS or DNS exercises, 60 minutes per session, 3 times a week during the 5 weeks. OUTCOME MEASURES: Balance function was measured as the primary outcome measure. Trunk function, postural stability, falling rate, fear of falling, falling index, mobility, and spasticity were measured as secondary outcomes. RESULTS: DNS group had significant improvement in Berg balance scale, trunk impairment scale, postural stability, activities-specific balance confidence, reduced falling rate, the timed Up and Go (TUG), multiple sclerosis walking scale-12, and multiple sclerosis spasticity scale in PWMS compared with the CS group, (P<.0001) after 5 weeks of intervention and 17 weeks of follow-up. Except for the modified Ashworth scale (MAS), significant improvements were seen in all outcome measures in both groups after 5 weeks of intervention. CONCLUSION: This is the first clinical evidence to support the importance of DNS exercise in improving balance, trunk function, and fall prevention in PWMS. This study provides clinical evidence that DNS may be more effective for PWMS than CS.

Effect of dynamic neuromuscular stabilization on balance and trunk function in people with multiple sclerosis: protocol for a randomized control trial.

BACKGROUND: Multiple sclerosis is a chronic and disabling neurological disease among young people. One of the major complaints in patients with multiple sclerosis (PWMS) is falling. There are a number of factors that risk factors for falling, including balance disorder and spasticity. Core stability (CS) exercises such as trunk muscle strengthening exercises can improve balance and mobility and reduce falling. Dynamic neuromuscular stabilization (DNS) exercise is a new functional rehabilitation strategy that optimizes motor function based on the principles of developmental kinesiology. This trial will evaluate the effectiveness of DNS in comparison to CS on balance, spasticity, and falling in PWMS. METHODS: A total of 64 PWMS, between 30 and 50 years old and expanded disability status scale (EDSS) between 2 to 5, will be recruited from neurophysiotherapy clinic, Faculty of Rehabilitation Sciences, Iran University of Medical Sciences to participate in this 2-armed parallel study. Participants will be randomly divided into two groups to receive CS exercise or DNS exercise. All participants will receive exercise treatment for 15 sessions during a period of 5 weeks (3 sessions per week). Primary outcome measures will be balance. Falling rate, fear of falling, patient mobility, as well as spasticity, will be measured as secondary outcomes. All outcome measures will be measured at baseline, the day after the completion of the 15th session, and after 17 weeks. DISCUSSION: Dynamic neurostabilization exercises utilize the subconscious stimulation of special zones to reflexively mediate the diaphragm and other core stabilization muscles, which is extremely effective for individuals with reduced somatosensory or movement awareness. Findings from the proposed study are expected to benefit the knowledge base of the physiotherapist, and it can be a good alternative for the rehabilitation program and even reduce medication use in patients with multiple sclerosis. These exercises are easy to understand and applicable for these patients and their partners as well. TRIAL REGISTRATION: The trial was registered in the Iran registry organization with code IRCT20140222016680N5 and was approved on April 7th, 2020. Address: IRCT administration team, Central Library Building, Iran University Campus, Hemmat Freeway, next to Milad tower, Tehran, Iran. postal code:14496-14535.

Anxiety and cognitive load affect upper limb motor control in Parkinson's disease during medication phases.

Anxiety is among the most debilitating nonmotor symptoms of Parkinson's disease (PD). This study aimed to determine how PD patients with low and high levels of anxiety (LA-PD and HA-PD, respectively) compare with age- and sex-matched controls at the level of motor control of reach-to-grasp movements during single- and dual-task conditions with varying complexity. Reach-to-grasp movement kinematics were assessed in 20 LA-PD, 20 HA-PD, and 20 sex- and age-matched healthy controls under single- as well as easy and difficult dual-task conditions. Assessment of PD patients was performed during both the on- and off-drug phases. The results obtained during dual-task conditions reveal deficits in both reach and grasp components for all three groups (e.g., decreased peak velocity and delayed maximum hand opening). However, these deficits were significantly greater in the PD groups, especially in the HA-PD group. Although dopaminergic medication improved reach kinematics, it had no effect on grasp kinematics. The results of our study indicated that high levels of anxiety may enhance the inefficiency of upper limb motor control in PD patients, especially during high demanding cognitive conditions, and should, therefore, be considered in the assessment and planning of interventions for upper limb function in these patients.

Influence of citicoline on citalopram-induced antidepressant activity in depressive-like symptoms in male mice.

Depression is associated with significant functional disabilities. Application of new drugs which could enhance the effectiveness of antidepressants drug and reduce side effects of their long-term use seems necessary. Citicoline is used as an effective chemical agent for improving the symptoms of some neurodegenerative diseases. Therefore, in this survey, the application of citicoline as an adjuvant drug was evaluated in mice model of depression. A total of 180 adult NMRI male albino mice were used in this study. All groups were exposed to chronic unexpected mild stress (CUMS) followed by treatment with various doses of citalopram or/and citicoline or saline for 21 days. Sucrose preference (SP), open field (OF), and forced swimming test (FST) were applied to evaluate depression symptoms in the groups. The results indicated that only citicoline at the 5 mg/kg dose had shifted its status from being noneffective to become significantly effective in the co-administered group. The means of SP, OFT, and FST of the treatment groups were significantly different in favor of co-administered group compared with the other groups as well as the control group. Based on the results, it can be concluded that administration of citicoline, as an adjuvant drug, in combination with citalopram, enhanced the effectiveness of selective serotonin reuptake inhibitors (SSRI) drugs for depression treatment.

Citicoline Combination Therapy for Major Depressive Disorder: A Randomized, Double-Blind, Placebo-Controlled Trial.

OBJECTIVE: Residual symptoms of major depressive disorder are a source of long-term morbidity. New therapeutic strategies are required to alleviate this morbidity and enhance patient quality of life. Citicoline has been used for vascular accidents and has been effective in cognitive rehabilitation. It has been used successfully to reduce craving in patients with substance abuse disorder and for mood management of bipolar disorder. Here, we test citicoline effectiveness as an adjuvant therapy in major depression. METHOD: A double-blind randomized trial was designed on 50 patients with major depressive disorder who were under treatment with citalopram. Patients were allocated to 2 groups and received citicoline (100 mg twice a day) or placebo as an adjuvant treatment for 6 weeks. Depressive symptoms were assessed by the Hamilton Depression Rating Scale (HDRS) at baseline and at weeks 2, 4, and 6. RESULTS: Significantly greater improvement was observed in the HDRS scores of the citicoline group compared with the placebo group from baseline to weeks 2, 4, and 6 (Ps = 0.030, 0.032, and 0.021, respectively). Repeated-measures general linear model demonstrated a significant effect for time × treatment interaction on the HDRS score (F2.10,101.22 = 3.12, P = 0.04). Remission rate was significantly higher in the citicoline group compared with the placebo group (P = 0.045). CONCLUSIONS: Citicoline was an effective adjuvant to citalopram in the therapy of major depressive disorder.

Changes of the brain's bioelectrical activity in cognition, consciousness, and some mental disorders.

Background: An electroencephalogram (EEG) is an accepted method in neurophysiology with a wide application. Different types of brain rhythms indicate that simultaneous activity of the brain cortex neurons depend on the person's mental state. Method: we have focus on reviewing the existing literature pertaining to changes of the brain's bioelectrical activity that recorded from the scalp in different conditions such as cognition and some mental disorders. Result: The frequency of brain waves may indicate sleep, consciousness, cognition, and some mental disorders. Slow brain waves are seen in some conditions such as sleep, coma, brain death, depression, autism, brain tumors, obsessive-compulsive disorder (OCD), attention deficit hyperactivity disorder (ADHD), and encephalitis, while rapid waves are generally reported in conditions such as epilepsy, anxiety, posttraumatic stress disorder (PTSD), and drug abuse. Conclusion: Increase in the EEG rhythm is a marker of high brain activity that leads to high degrees of consciousness, while slow waves are suggestive of less brain activity. The pattern of EEG rhythm can be an indicator of some mental disorders, too.
