Indicators of mineral bone density in male patients with osteoarthritis of knee joint of elderly and old age depending on condition of muscular system

Objective. To evaluate bone mineral density (BMD) indices in elderly and old age male patients with knee osteoarthritis (OA) depending on the state of the muscular system.Subjects and methods. The trial enrolled 32 patients with knee OA. The mean age of the patients was 68.7 (66.1; 70.3) years. The diagnosis of knee OA was established according to the diagnostic criteria of the American College of Rheumatologists (ACR, 1991). For comparative analysis, all patients with knee OA were divided into 3 groups according to muscle condition (EWGSOP, 2010: muscle mass was assessed by multispiral computed tomography, muscle strength was measured using a wrist dynamometer, muscle function was examined using a battery of short tests): the 1st – 9 patients without sarcopenia, the 2nd – 11 patients with presarcopenia, and the 3rd – 12 patients with sarcopenia. BMD was assessed by dual-energy X-ray absorptiometry in the neck and proximal femur as a whole and in the lumbar spine.Results. Osteopenic syndrome in the study cohort was diagnosed in 23 (71,9%) patients: osteopenia – in 19 (59,4%) patients, osteoporosis – in 4 (12,5%). Normal BMD values were observed in 9 (28.1%) patients. Osteopenic syndrome was detected in patients with sarcopenia signifcantly more often compared to patients without sarcopenia (p > 0.05) and with presarcopenia (p = 0.05). BMD indices in patients with sarcopenia in the neck and proximal femur in general were statistically signifcantly lower than in patients without sarcopenia and with presarcopenia (p < 0.05). There was a direct correlation between total skeletal muscle area at the LIII level and densitometric indices of the femoral neck.Conclusions. Sarcopenia is associated with low BMD indices in the neck and proximal femur in general in elderly and senile male patients with knee OA

Influence of millimeter electromagnetic waves on the functional capabilities of the lower limb muscles in athletes - volleyball players

The authors, when observing 22 athletes - volleyball players of different volleyball specialization, assessed the effect of millimeter electromagnetic waves (EMW) on the functional state of the muscular system of the lower extremities. The electromagnetic effect was carried out using the "Complex SP 80" apparatus (frequencies 3900 - 4120 kHz were used). Electrodes were applied to the muscles of the thigh and lower leg, sinusoidal discharges were applied for 10 seconds during the strength training period. The results of observations showed that under the influence of EME, the height of the jump increases by 7%, due to the increase in the energy of the jump and its intensity. The release of the activity of the knee joint is also noted. The authors believe that under the influence of EME, the transmission of regulatory impulses in neuromuscular contact improves, which contributes to the synchronization and strength of contractions of the muscle fiber bundles. Also, under the influence of EMW, blood microcirculation in the muscle improves.

Bioimpedance Analysis of Human Body Composition: Medical Applications, Terminology.

This article discusses the terminology features of bioimpedance analysis of body composition and the most common mistakes in the use of terms. In the Russian-speaking medical environment, you can often find the use of a number of inaccurate terms related to bioimpedance analysis of the human body composition. At the same time, the terminology of bioimpedance analysis of human body composition in English-language publications has long been established. The article presents the Russian and English terms of bioimpedance analysis of the human body composition with corresponding abbreviations, as well as the hierarchy of the terms body composition components, body composition parameters, parameters of bioimpedance analysis of body composition and bioimpedance parameters. The most developed areas of application of bioimpedance analysis in medical practice are discussed: assessment of nutrition and dynamic observations of changes in body composition, assessment of the body mineral mass, assessment of the body hydration parameters, assessment of blood supply to tissues and organs, including in the monitoring mode, assessment of the asymmetry of paired organs and limbs, assessment of pre-start readiness, physical development and the level of fitness of the athlete's muscular system.

Phase angle. Medical interpretations and applications.

The choice of the topic of this work is due to the interest of specialists using bioimpedance technology for assessing the rate of metabolic processes and body composition, to the possibilities of the clinical application of the phase angle. Phase angle (PhA) is a parameter specific only to the bioimpedance method of obtaining information about body composition. In the early 2000s, it was shown that low PhA values in catabolic diseases can be used to assess survival, while high values can be used to assess the fitness of the muscular system in athletes and other individuals who regularly exercise. Systematic reviews and meta-analyzes of subsequent years have summarized the evidence base of these provisions and identified a number of new applications - in sarcopenia, anorexia, and renal failure. In assessing nutrition, PhA is used to indirectly characterize both the protein fraction of the body and the rate of metabolic processes.

Proposed Mechanisms of Blood Flow Restriction Exercise for the Improvement of Type 1 Diabetes Pathologies

Individuals with type 1 diabetes suffer from impaired angiogenesis, decreased capillarization, and higher fatigability that influence their muscular system beyond the detriments caused by decreased glycemic control. In order to combat exacerbations of these effects, the American Diabetes Association recommends that individuals with type 1 diabetes participate in regular resistance exercise. However, traditional resistance exercise only induces hypertrophy when loads of ≥65% of an individual’s one repetition maximum are used. Combining blood flow restriction with resistance exercise may serve as a more efficient means for stimulating anabolic pathways that result in increased protein synthesis and angiogenesis at lower loads, while also promoting better glycemic control. The purpose of this paper is to provide a review on the literature surrounding the benefits of resistance exercise, specifically for individuals with type 1 diabetes, and postulate potential effects of combining resistance exercise with blood flow restriction in this clinical population.

Comparative Study of the Efficacy of Biofeedback-Assisted Jacobsons Progressive Muscle Relaxation (Jpmr) for Managingmild/Moderate Depression

Biofeedback is the way of gaining greater awareness of physiological functions with a goal of self-regulation. JPMR (Jacobsons progressive muscle relaxation) causes release of tension in the skeletal muscles, neuro-muscular system is thus seen as a mediator in the relief of depressive symptoms. This study aimed to see the Comparative efficacy of Biofeedback assisted JPMR, Escitalopram and Bimodal use of both in management in mild/moderate depression. The study was conducted at Mental hospital, Indore, with a Sample Size of 30 [Group A 10 ; biofeedback ,Group B 10 ; Escitalopram ,Group C 10;both]. 8 sessions of biofeedback assisted JPMR was given to group A and C .Escitalopram was given group B and C. HAM-D and BDI was applied at baseline , 4 weeks and 8 weeks. As per BDI scale scores, Biofeedback assisted JPMR combined with escitalopram has significantly better response than only biofeedback or only Escitalopram in patients of mild to moderate depression. As per HAM-D scale scores, Biofeedback assisted JPMR combined with escitalopram has significantly better response than only biofeedback or only Escitalopram in patients of mild to moderate depression. Thus Biofeedback appears to be a useful adjunctive treatment for mild to moderate depressive episode.
