Assessment of Quality of Life and Pain Severity in Older Men with Osteoporosis: Cross-Sectional Study.

BACKGROUND: The quality of life in osteoporosis is studied for men rather than for women. Aim of the study was to determine how bone mass density (BMD) relates to life quality components and the severity of pain felt by men affected by osteoporosis. METHODS: Presented research is a cross-sectional study. The cohort of 62 men aged 65 to 85 years was divided into a group with osteoporosis (N = 27) and a group without osteoporosis (N = 35). The participants' quality of life was measured with the Qualeffo41 Questionnaire, BMD was quantified by densitometry, and pain intensity was assessed on the Visual Analogue Scale. RESULTS: We found that lower BMD was strongly correlated to participants' quality of life (r = -0.72), especially the quality of leisure and social activities (r = -0.66), general health perception (r = -0.59), and mobility (r = -0.57). Pain significantly affected general health perception in older men with osteoporosis. General health assessment and pain were highly correlated with each other (r = 0.888). CONCLUSION: BMD and the overall quality of life of the study participants were related to each other. The strongest relationship occurred between reduced BMD and leisure and social activities component. The pain significantly affected participants' general health perception. The results may be employed to create new prophylactic strategies to improve life quality in men with osteoporosis.

The Combined Effect of Neuromuscular Electrical Stimulation and Insulin Therapy on Glycated Hemoglobin Concentrations, Lipid Profiles and Hemodynamic Parameters in Patients with Type-2-Diabetes and Hemiplegia Related to Ischemic Stroke: A Pilot Study.

Type-2-diabetes mellitus (T2DM) is a global problem of medical, social and economic consequences. Physical activity is a vital therapy in patients with T2DM, but some of them cannot exercise for various reasons. The purpose of our pilot study was to determine whether a combination of neuromuscular electrostimulation (NMES) and insulin therapy could improve the management of T2DM patients with hemiplegia caused by an ischemic stroke. Fifteen immobile patients with T2DM on insulin therapy were enrolled in the study. NMES was applied to their lower limbs for 60 min, 5 days a week, over a period of 12 weeks. The intervention caused statistically significant reductions in the blood concentrations of glycated hemoglobin, total cholesterol and low-density cholesterol in the participants. Furthermore, systolic and diastolic blood pressure levels were significantly lower. More randomized clinical trials are needed to accurately measure the effect of NMES on T2DM treatment and to determine whether it can be an alternative for physical activity for immobile patients with T2DM.

Pressure Injuries Treated With Anodal and Cathodal High-voltage Electrical Stimulation: the Effect on Blood Serum Concentration of Cytokines and Growth Factors in Patients With Neurological Injuries. A Randomized Clinical Study.

It remains unclear whether electrical currents can affect biological factors that determine chronic wound healing in humans. PURPOSE: The aim of this study was to determine whether anodal and cathodal high-voltage monophasic pulsed currents (HVMPC) provided to the area of a pressure injury (PI) change the blood level of cytokines (interleukin [IL]-1ß, IL-10, and tumor necrosis factor [TNF]-α) and growth factors (insulin-like growth factor [IGF]-1 and transforming growth factor [TGF]-ß1) in patients with neurological injuries and whether the level of circulatory cytokines and growth factors correlates with PI healing progression. METHODS: This study was part of a randomized clinical trial on the effects of HVMPC on PI healing. All patients with neurological injuries (spinal cord injury, ischemic stroke, and blunt trauma to the head) and a stage 2, stage 3, or stage 4 PI of at least 4 weeks' duration hospitalized in one rehabilitation center were eligible to participate if older than 18 years of age and willing to consent to donating blood samples. Exclusion criteria included local contraindications to electrical stimulation (cancer, electronic implants, osteomyelitis, tunneling, necrotic wounds), PIs requiring surgical intervention, patients with poorly controlled diabetes mellitus (HbA1C > 7%), critical wound infection, and/or allergies to standard wound treatment. Participants were randomly assigned to 1 of 3 groups: anodal (AG) or cathodal (CG) HVMPC treatment (154 µs; 100 Hz; 360 µC/sec; 1.08 C/day) or a placebo (PG, sham) applied for 50 minutes a day, 5 days per week, for 8 weeks. TNF-α, IL-1ß, IL-10, TGF-ß1, and IGF-1 levels in blood serum were assessed using the immunoenzyme method (ELISA) and by chemiluminescence, respectively, at baseline and week 4. Wound surface area measurements were obtained at baseline and week 4 and analyzed using a digitizer connected to a personal computer. Statistical analyses were performed using the maximum-likelihood chi-squared test, the analysis of variance Kruskal-Wallis test, the Kruskal-Wallis post-hoc test, and Spearman's rank order correlation; the level of significance was set at P ≤.05. RESULTS: Among the 43 participants, 15 were randomized to AG (mean age 53.87 ± 13.30 years), 13 to CG (mean age 51.08 ± 20.43 years), and 15 to PG treatment (mean age 51.20 ± 14.47 years). Most PIs were located in the sacral region (12, 74.42%) and were stage 3 (11, 67.44%). Wound surface area baseline size ranged from 1.00 cm2 to 58.04 cm2. At baseline, none of the variables were significantly different. After 4 weeks, the concentration of IL-10 decreased in all groups (AG: 9.8%, CG: 38.54%, PG: 27.42%), but the decrease was smaller in the AG than CG group (P = .0046). The ratio of pro-inflammatory IL-10 to anti-inflammatory TNF-α increased 27.29% in the AG and decreased 26.79% in the CG and 18.56% in the PG groups. Differences between AG and CG and AG and PG were significant (AG compared to CG, P = .0009; AG compared to PG, P = .0054). Other percentage changes in cytokine and growth factor concentration were not statistically significant between groups. In the AG, the decrease of TNF-α and IL-1ß concentrations correlated positively with the decrease of PI size (P <.05). CONCLUSION: Anodal HVMPC elevates IL-10/TNF-α in blood serum. The decrease of TNF-α and IL-1ß concentrations in blood serum correlates with a decrease of PI wound area. More research is needed to determine whether the changes induced by anodal HVMPC improve PI healing and to determine whether and how different electrical currents affect the activity of biological agents responsible for specific wound healing phases, both within wounds and in patients' blood. In clinical practice, anodal HVMPC should be used to increase the ratio of anti-inflammatory IL-10 to pro-inflammatory TNF-α , which may promote healing.

A Randomized, Controlled Clinical Study to Assess the Effect of Anodal and Cathodal Electrical Stimulation on Periwound Skin Blood Flow and Pressure Ulcer Size Reduction in Persons with Neurological Injuries.

The use of electrical stimulation (ES) should be considered for treating nonhealing pressure ulcers (PUs), but optimal ES wound treatment protocols have yet to be established. A randomized, controlled, double-blind clinical study was conducted to evaluate the effects of cathodal and anodal high-voltage monophasic pulsed current (HVMPC) on periwound skin blood flow (PSBF) and size reduction of Stage 2 to Stage 4 PUs of at least 4 weeks' duration. Persons >18 years of age, hospitalized with neurological injuries, at high risk for PU development (Norton scale <14 points; Waterlow scale >15 points), and with at least 1 Stage 2 to Stage 4 PU were eligible to participate in the study. Persons with necrotic wounds, osteomyelitis, electronic or metal implants in the PU area, PUs in need of surgical intervention, acute wound inflammation, diabetes (HBA1c >7%), diabetic neuropathy, cancer, and/or allergies to standard wound treatments were excluded. Patients were randomly assigned to 1 of 3 groups: anodal (AG), cathodal (CG), or placebo (PG) ES. All groups received individualized PU prevention and standard wound care. In the PG, sham ES was applied; the AG and CG were treated with anodal and cathodal HVMPC, respectively (154 µs 100 Hz; 360 µC/second; 1.08 C/day), 50 minutes per day, 5 days per week, for a maximum of 8 weeks. PSBF was measured using laser Doppler flowmetry at baseline, week 2, and week 4, and wound surface area measurements were obtained and analyzed using a digitizer connected to a personal computer. Data analysis utilized the maximum-likelihood chi-squared test, the analysis of variance Kruskal-Wallis test, the Kruskal-Wallis post-hoc test, and Spearman's rank order correlation. Nonlinear approximation based on exponential function was used to calculate treatment time needed to reduce the wound area by 50%. In all tests, the level of significance was set at P ≤.05. Of the 61 participating patients, 20 were in the AG (mean age 53.2 ± 13.82 years), 21 in the CG (mean age 55.67 ± 17.83 years), and 20 in the PG (mean age 52.5 ± 13.18 years). PUs (baseline size range 1.01 cm2 to 59.57 cm2; duration 4 to 48 weeks) were most frequently located in the sacral region (73.77%) and classified as Stage 3 (62.29%). PSBF at week 2 was significantly higher in the AG and CG than in the PG (P <.05). Week 4 differences were not statistically significant. Wound percentage area reduction calculated at week 8 for the AG (64.10% ± 29.22%) and CG (74.06% ± 23.23%) were significantly different from PG ulcers (41.42% ± 27.88%; P = .0391 and P = .0024, respectively). In both ES groups, PSBF at week 4 and percent wound surface area reductions between weeks 4 and 8 were positively correlated, but only the AG correlation was statistically significant (P = .049). In this study, both ES modalities improved blood flow and wound area reduction rate. Studies examining optimal ES treatment times for healing to occur, the effect of comorbidities and baseline wound variables on ES outcomes, and the nature of the relationship between blood flow and healing are necessary.

Exercise-Based Cardiac Rehabilitation with and Without Neuromuscular Electrical Stimulation and its Effect on Exercise Tolerance and Life Quality of Persons with Chronic Heart Failure.

The study compares the effect of an exercise-based cardiac rehabilitation program with a program combining physical exercise and lower extremity neuromuscular electrical stimulation (NMES) on the recovery of patients with chronic heart failure (CHF) with NYHA II-III symptoms. Seventy two patients with stable CHF were randomly distributed to four groups that received exercise-based cardiac rehabilitation and pharmacological treatment. Groups I and II were additionally administered NMES (35 Hz and 10 Hz, respectively) and in Group III sham NMES was applied. Group IV (controls) received solely pharmacological and exercise treatment. Exercise tolerance and quality of life were assessed in patients pre-treatment and at week 3. Three weeks of rehabilitation induced significant increases (p < 0.05) in the distance covered in the 6-minute walk test, the metabolic equivalent (MET), the duration of the treadmill exercise stress test, the left ventricle ejection fraction (LVEF) and improved quality of life in all groups, but between-group differences were not significant (p > 0.05). In none of the groups were the left ventricle end-systolic and end-diastolic diameters (mm) measured at week 3 significantly different from their baseline values (p > 0.05). Exercise-based cardiac rehabilitation contributed to higher exercise tolerance, LVEF and quality of life of CHF patients (NYHA II-III), contrary to cardiac rehabilitation combined with lower extremity NMES (35 Hz and 10 Hz) that failed to induce such improvements. More research is necessary to assess the therapeutic efficacy of NMES applied to CHF patients with NYHA IV symptoms.

Evaluation of the Effects of Neuromuscular Electrical Stimulation of The Lower Limbs Combined with Pulmonary Rehabilitation on Exercise Tolerance in Patients with Chronic Obstructive Pulmonary Disease.

Chronic obstructive pulmonary disease (COPD) is a systemic disease with multiple extrapulmonary manifestations including impeded skeletal muscle function, leading to decreased muscular strength and endurance in patients with COPD. Pulmonary rehabilitation eases the symptoms of the condition and produces increased muscular endurance. Neuromuscular electrical stimulation (NMES) may serve as a treatment alternative to traditional pulmonary rehabilitation. The aim of the study was to assess the effects of NMES combined with pulmonary rehabilitation on exercise tolerance in patients in comparison with pulmonary rehabilitation alone. The subjects included 30 patients with COPD randomly assigned to one of the two groups. The first group consisted of 15 patients who were treated with neuromuscular electrical stimulation at frequency of 35Hz and pulmonary rehabilitation (NMES+RP). The second group comprised 15 patients treated with pulmonary rehabilitation only (RP). Pre- and poststudy assessments were performed. The retrospective evaluation including an exercise tolerance test (i.e. six minute walk test (6MWT)), spirometry and blood gasometry was carried out after 3 weeks. Twenty-eight patients in total completed the study. In the NMES+RP group, an increase in exercise tolerance manifested by a longer distance walked in the 6MWT was observed in comparison to the pulmonary rehabilitation group. No effects of NMES combined with pulmonary rehabilitation on selected spirometric and gasometric parameters in patients with COPD were observed in comparison with traditional pulmonary rehabilitation. The acquired results suggest that NMES of the lower limbs may be applied as an additional form of pulmonary rehabilitation in patients with COPD.
