Although the total “Timed-Up-and Go” test (TUG) performance time can characterize an age-related decline of general mobility, this result alone doesn’t give any detailed information about the test subtasks. The primary objective of the study was to identify in nursing home women a variable extracted from instrumented TUG (iTUG) that is the best predictor of age. The secondary objective was to assess whether this variable is associated with the results of the isometric knee extension peak torque (IKEPT); lower limb strength measured by the 30-s chair stand test (30sCST), and walking capacity measured by the 6-min walk test (6MWT). Twenty-six women (mean ± SD: age—85.8 ± 3.6 years; body weight—59.4 ± 12.3 kg; body height—151.0 ± 7.3 cm; BMI—26.0 ± 4.9 kg/m²) performed iTUG (while wearing a body-fixed inertial sensor) and functional tests. Total iTUG performance time significantly correlated with age (r = 0.484; p < 0.05), 30sCST (r = −0.593; p < 0.01), and 6MWT (r = −0.747; p < 0.001) but not with absolute nor relative IKEPT (p > 0.05). Additionally, the subjects’ age correlated with 30sCST (r = −0.422; p < 0.05), 6MWT (r = −0.482; p < 0.05), IKEPT (r = −0.392; p < 0.05) and IKEPT/FFM (r = −0.407; p < 0.05). Five out of 16 analyzed iTUG variables were significantly related to age, and multiple regression analysis showed the best correlation with the sit-to-stand vertical acceleration range (STSVAR) (r² = 0.430; SEE = 3.041; β = −0.544 ± 0.245; B = −1.204 ± 0.543; p < 0.05). Moreover, STSVAR was significantly associated with %Fat (r = 0.415; p < 0.05), 30sCST (r = 0.519; p < 0.01), 6MWT (r = 0.585; p < 0.01) but not with absolute nor relative IKEPT (p > 0.05). The obtained results suggest that in the oldest old group of nursing home women an age-related decline in TUG performance is mainly associated with a reduction of “explosive” strength of lower limb muscles.

Objective: International guidelines recommend the use of ultrasound (US) and electrical stimulation (ES) for treating chronic and recurrent pressure ulcers (PUs). The methodology of these procedures, however, still needs elaboration and confirmation by clinical studies. This parallel-group, randomised, single-blind, prospective, controlled clinical trial was conducted to determine whether by using high-frequency ultrasound (HFUS) and high-voltage monophasic pulsed current (HVMPC), the rate of change in the area of older patients' PUs can be accelerated.Method: Patients were randomly assigned to receive either: standard wound care (SWC) involving supportive care and topical treatments; SWC+US (1MHz; 0.5 W/cm²; 20%; 1–3 minutes/cm2); or SWC+ES (HVMPC, 154 µs, 100 pps, 100 V, 250 µC/sec, 50 minutes/day). US and ES were administered once a day, 5 days a week. The primary outcome was change in PU surface area measured against baseline after 6 weeks of treatment with SWC, SWC+US, and SWC+ES.Results: We recruited 77 patients, aged 60–95 years (80% aged over 70 years of age), with 88 Category II, III and IV PUs were enrolled in the study. The percentage reduction in the surface area of PUs at the end of treatment was significantly greater in the SWC+US group (mean ± standard deviation, 77.48±11.59 %; p=0.024) and the SWC+ES group (76.19±32.83%; p=0.030) versus the control group (48.97±53.42%). The SWC+ES group also had a significantly greater proportion of PUs that decreased in area by at least 50% or closed than the control group (p=0.05 and 0.031, respectively). The SWC+US and SWC+ES groups were not statistically significant different regarding treatment results. Clinical side effects were not recorded.Conclusion: The results show that HFUS and HVMPC are comparable regarding their effectiveness in reducing the size of PUs in older people.Declaration of interest: The authors have nothing to disclose.

Background. Studies show that anode and cathode ES promote the healing of wounds, but specific protocols for both electrodes are not available Objective. To compare the effectiveness of cathodal versus cathodal+anodal ES in the treatment of Category II-IV pressure ulcers (PrUs) Design. Prospective, randomized, controlled, clinical study Setting. Three nursing and care centers Patients. 63 participants with PrUs were randomly formed into a cathodal ES group (CG/N = 23) mean age of 79.35; SD 8.48), a cathodal+anodal ES group (CAG/N = 20; mean age of 79.65; SD 11.44) and a placebo ES group (PG/N = 20; mean age of 76.75; SD 12.24) Intervention. All patients were treated with standard wound care and high-voltage monophasic pulsed current (HVMPC; twin-peak impulses; 154 μs; 100 pps; 0.25 A; 250 μC/sec) for 50 minutes per day, five times a week, for 6 weeks. The CG, CAG and PG received, respectively, cathodal, cathodal plus anodal, and sham ES through electrodes placed on a moist gauze pad. The treatment electrode was placed on the wound, the return electrode was positioned on healthy skin at least 20 cm from the PrU. Measurements. Measurements were made at baseline, and after each of the six weeks of treatment. Primary outcome was percentage wound surface area reduction at week 6. Results: In the CG, wound surface area decreased by 82.34% (95% confidence interval [CI] 70.06-94.63) and in the CAG by 70.77% (95%CI 53.51-88.04). These reductions were significantly greater than in the PG (40.53%; 95%CI 23.60-57.46). The CG and CAG were not statistically significant different regarding treatment results. Limitations: The time of treatment proved insufficient for PrUs to close Conclusion: Cathodal and cathodal+anodal HVMPC similarly reduced the area of Category II-IV PrUs

OBJECTIVE: To investigate the effectiveness of high-voltage monophasic pulsed current (HVMPC) as an adjunct to a standard wound care for the treatment of Stage II and III pressure ulcers (PrUs). DESIGN: Prospective, randomized, double-blind, controlled clinical study. SETTING: Two nursing and care centers. PATIENTS: Patients with PrUs that did not respond to previous treatment for at least 4 weeks were randomly assigned to the electrical stimulation (ES) group (25 patients; mean age of 79.92 ± 8.50 years; mean wound surface area [WSA] of 10.58 ± 10.57 cm²) or to the control group (24 patients; mean age of 76.33 ± 12.74 years; mean WSA of 9.71 ± 6.70 cm²). INTERVENTIONS: Both the ES and control groups received standard wound care and respectively, cathodal HVMPC (154 microseconds; 100 pulses per second; 0.24 A; 250 μ/s) applied continuously for 50 minutes once a day, 5 times a week, or sham HVMPC. MAIN OUTCOME: Percentage area reduction over 6 weeks of intervention. MAIN RESULTS: In the ES group, there was a statistically significant decrease in WSA after 1 week of treatment (35% ± 30.5%) compared with 17.07% ± 34.13% in the control group (P = .032). After treatment, at week 6, percentage area reduction in the ES group was 80.31% ± 29.02% versus 54.65% ± 42.65% in the control group (P = .046). CONCLUSIONS: Cathodal HVMPC reduces the WSA of Stage II and III PrUs. The results are consistent with the results of other researchers who used HVMPC to treat PrUs.

Osteoporosis is one of the most common diseases that develop with age and cause high morbidity and mortality among elderly people. This study was set out to evaluate the influence of a program of modified Sinaki exercises, Nordic walking (NW) and a combination of these physical activities on people with osteoporosis. A sample consisting of 91 women aged 65-98 years living in residential care facilities was randomized into 4 groups. The control group (group 1) received only pharmacological treatment. In the other 3 groups, the same drug therapy was enhanced by a program of modified Sinaki exercises (group 2), Nordic walking (group 3), and Sinaki exercises and Nordic walking applied together (group 4). At baseline and after 12 months of intervention, the participants were assessed for bone density, rib cage mobility, motor abilities, risk of falling (Timed Up and Go Test - TUG, Functional Reach Test - FRT), and locomotor activity (based on pedometer readings). The intervention was completed by 83 participants. Bone density (T-score) was higher in all intervention groups and in the control group (p < 0.003). The improvement in rib cage mobility was statistically significant in groups 2 (p < 0.001) and 4 (p < 0.002). Locomotor activity significantly improved in groups 3 (p < 0.000) and 4 (p < 0.000). The post-intervention results of the TUG and FRT tests showed a significantly lower risk of falling in group 4. In groups 1 and 2, the risk was higher, but not statistically significantly, and in group 3, it did not change. Modified Sinaki exercises and Nordic walking significantly improved the mobility of the rib cage, locomotor activity and motor abilities in the women comprising groups 2 and 3, but the best results of the intervention were noted in the group treated with both forms of physical activity.

Background: Osteoporosis is a skeletal disease. It is still not known which of the risk factors have the greatest impact on osteoporosis development. The study aimed to determine how the selected osteoporosis risk factors contribute to the development of the disease and to assess the risk of osteoporotic fractures in older women. Methods: A cohort of 99 older females was divided into two groups (with and without osteoporosis). The risk of osteoporosis was determined using assessment forms and bone densitometry data subjected to logistic regression. The risk of osteoporotic fractures was assessed by the FRAX tool (FRAX, Center for Metabolic Bone Diseases, University of Sheffield, UK). Results: The logistic regression analysis showed that the highest risk of developing osteoporosis associated with lifestyle, mainly cigarette smoking (odds ratio: OR = 2.12), past gynecological operations (OR = 1.46), corticosteroid therapies (OR = 1.38). More than half of participants were at a medium risk of femoral neck fractures (over 90% in the osteoporotic group). Conclusion: Most of the Polish women living in care facilities are at medium risk of low-energy fractures. Smoking appeared to have the strongest effect on osteoporosis among analyzed risk factors. The results may contribute to the creation of more appropriate prevention strategies.
