Relation between risk of falls, sarcopenia and parameters assessing quality of skeletal muscles in a group of postmenopausal women.

INTRODUCTION: Involutional changes that occur in skeletal muscle are a feature that characterizes the aging process. In women, age-related decreases in muscle mass and function of skeletal muscles occur more rapidly with the onset of menopause. Progressive muscle dysfunction has been directly linked with an increased probability of falls, fractures, disability and mortality. AIM OF THE STUDY: To assess the relationship between the risk of falls and parameters of skeletal muscle assessment in a group of postmenopausal women together with the identification of patients with sarcopenia. MATERIAL AND METHODS: This study was carried among 122 women over 60 years of age. Patients had their muscular system tested with the emphasis on the sarcopenia diagnosis using: Total Body Composition, handgrip and physical performance tests. Patients also underwent a questionnaire survey assessing occurrence of falls. RESULTS: The analysis showed an over 2-fold increase (OR 2.4; 95% CI, 1.02-5.56) in risk of falls in a year among subjects with decreased muscle mass. No such correlation was noted with parameters such as falls in the last 12 months and decrease of muscle strength as well as physical performance. Sarcopenia is more likely to be diagnosed with European Working Group on Sarcopenia in Older People (EWGSOP1) criteria than EWGSOP2 (updated in 2018) (18% vs. 4.1% respectively). The increased risk of falls has not been proven in women with sarcopenia. CONCLUSIONS: The decrease of muscle mass is significantly correlated with the risk of falls in the last year in postmenopausal women. Impact of sarcopenia on the risk of falls depends on diagnostic criteria.

Vertebral fracture assessment, trabecular bone score and handgrip in a group of postmenopausal women with vertebral fractures - preliminary study.

OBJECTIVES: The aim of our study was to determine a possible correlation between vertebral fractures (indicated by VFA - vertebral fracture assessment), TBS (trabecular bone score) and muscle strength (measured by means of handgrip strength test results) in a group of postmenopausal women. MATERIAL AND METHODS: The study was conducted between 2014 and 2015 in a group of patients of Krakow Medical Centre (KMC). Women who participated in the study were referred to KMC by an attending physician for suspected vertebral fracture. Apart from VFA, patients were additionally tested for bone density (including TBS), muscle strength (by means of a handgrip strength test) and height loss. Altogether 35 patients with an average age of 69.7 years (49-95, SD = 10.49) were included in the study. RESULTS: In the group of 35 women, VFA analysis demonstrated vertebral fractures in 17 patients (40%). Vertebral height loss suggesting a fracture was revealed in 77 vertebrae. The mean result of the TBS was 1.195 (0.982-1.409, SD = 0.09), which suggests high risk of fracture. The majority of the subjects (65.7%) displayed major bone microarchitecture degradation (TBS < 1.23) and also the highest number of fractures (n = 62, 80.5% of all). There was no correlation between the spine bone mineral density (BMD) score and the TBS result, which confirms studies showing that subjects with the same bone density may have completely different TBS. Bone density (spine BMD) was similar (osteopenic) in groups with or without vertebral fracture (in VFA). We noted a significant correlation (r = 0.45, p < 0.05) between the number of fractured vertebrae and the handgrip score. CONCLUSIONS: VFA should be a part of a standard diagnostic procedure for patients with osteoporotic fractures. When it comes to identifying patients at risk of fracturing vertebrae, muscle strength (handgrip) may have potential use in clinical practice. The predictive value of the TBS in reference to vertebral fractures should be evaluated in bigger randomized studies.

Intermittent Claudication in Physiotherapists' Practice.

Intermittent claudication is a symptom of atherosclerosis of the lower limbs (peripheral arterial disease (PAD)) and is characterized by pain and cramps of lower limb muscles during exercise. Claudication leads to a reduction in physical activity of patients. PAD is a systemic disease. Atherosclerotic lesions located in the arteries of the lower limbs not only pose the risk of the ischemic limb loss, but above all, they are an important prognostic factor. Patients with claudication are at significant risk of cardiovascular complications such as infarcts or strokes. Comprehensive rehabilitation of patients with intermittent claudication based on the current TASC II (Inter-Society Consensus for the Management of Peripheral Arterial Disease) guidelines, ESC (European Society of Cardiology) guidelines, and AHA (American Heart Association) guidelines includes supervised treadmill training, training on a bicycle ergometer, Nordic Walking, resistance exercises of lower limb muscles, and exercises of upper limbs. A trained, educated, and motivated patient has a chance to improve life quality as well as life expectancy.

Trabecular Bone Score (TBS) in Clinical Practice - Rewiev.

Bone mineral density (BMD) assessment is the basic method for assessing fracture risk and diagnosing osteoporosis according to the World Health Organization (WHO). Osteoporosis is diagnosed when the T-score at the proximal femur or spine is T≤-2.5; however, 70% of fractures occur in patients who do not fulfil this criterion. As BMD alone does not adequately predict fracture risk, additional methods supporting risk assessment are needed [3,4]. In 2012, the US Food and Drug Administration (FDA) adopted the Trabecular Bone Score (TBS) as another diagnostic method for osteoporosis. The aim of this study is to evaluate the use of TBS in clinical practice with particular attention to fracture risk assessment, differential diagnosis and assessment of treatment outcomes in patients suffering from primary or secondary osteoporosis. Literature analysis points to the increasing use of TBS in clinical practice. It has been found that, in different subjects with the same BMD, structural bone health is better differentiated using TBS. Additionally, it is valuable to use the DXA along with TBS analysis for improved prediction of fracture risk. Indirect assessment of bone structure with TBS is also helpful in assessing the effect of medications. In conclusion, TBS analysis is a valuable tool in the assessment of bone fracture risk and in the differential diagnosis of structural bone disorders in secondary osteoporosis.

Contemporary Management of Osteoporotic Fractures.

With aging of the population, osteoporotic fractures are becoming an increasing medical problem world-wide. It has been estimated that 2,700,000 patients experienced a low energy fracture in the Polish population in 2010. On the basis of contemporary world standards and publications in the field of orthopaedics and trau-matic surgery, a summary of the principles of management of osteoporotic fractures is presented. Both general problems of fracture treatment in elderly patients as well as difficulties in surgical and conservative treatment resulting from osteoporotic bone abnormalities are discussed. Special attention is paid to preoperative and postoperative procedures in patients with proximal femur fractures. Also presented is a contemporary strategy for the treatment of fractures of the distal forearm, proximal humerus and vertebrae. General principles of diagnosis and treatment of osteoporosis are discussed.
