Examination of a patient with chronic low back pain (LBP) is aimed at eliminating its specific cause and assessing the social and psychological factors of chronic pain. The diagnosis of chronic nonspecific (musculoskeletal) LBP is based on the exclusion of a specific cause of pain, discogenic radiculopathy, and lumbar stenosis. It is advisable to identify possible pain sources: pathology of intervertebral disc pathology, facet joints, and sacroiliac joint and myofascial syndrome.An integrated multidisciplinary approach (a high level of evidence), including therapeutic exercises, physical activity optimization, psychological treatments (cognitive behavioral therapy), an educational program (back pain school for patients), and manual therapy, is effective in treating chronic musculoskeletal LBP. For pain relief, one may use nonsteroidal anti-inflammatory drugs in minimally effective doses and in a short cycle, muscle relaxants, and a capsaicin patch, and, if there is depressive disorder, antidepressants (a medium level of evidence). Radiofrequency denervation or therapeutic blockages with anesthetics and glucocorticoids (damage to the facet joints, sacroiliac joint), back massage, and acupuncture (a low level of evidence) may be used in some patients.Therapeutic exercises and an educational program (the prevention of excessive loads and prolonged static and uncomfortable postures and the use of correct methods for lifting weights, etc.) are recommended for preventive purposes.

7 620028, Екатеринбург, ул. Репина, 3 У пациента с острой поясничной болью (ПБ) проводят оценку жалоб и данных анамнеза, краткое соматическое и неврологическое обследование, определяют наличие симптомов опасности. Диагноз острой неспецифической (скелетно-мышечной) ПБ основывается на исключении специфической причины боли (потенциально опасного заболевания), дискогенной радикулопатии и поясничного стеноза. В случаях типичной скелетно-мышечной боли, отсутствия симптомов опасности не рекомендуются проведение рентгенографии, рентгеновской компьютерной томографии, магнитно-резонансной томографии в первые 4 нед заболевания. Целесообразность их выполнения рассматривается при сохранении ПБ сверх этого времени. Пациент с острой неспецифической (скелетно-мышечной) ПБ должен быть проинформирован о благоприятном исходе заболевания, необходимости сохранять физическую и социальную активность, избегать постельного режима, при возможности продолжать профессиональную деятельность. Для облегчения боли можно использовать нестероидные противовоспалительные препараты в минимально эффективных дозах и коротким курсом, а также миорелаксанты (средний уровень доказательности). Части пациентов целесообразно назначить мануальную терапию и массаж спины (низкий уровень доказательности). Для предупреждения рецидивов ПБ рекомендуются образовательная программа (профилактика чрезмерных нагрузок, длительного пребывания в статических и неудобных позах, правильные способы подъема тяжестей и др.) и вне периода обострения -лечебная гимнастика.

Background: Vitamin D insufficiency is prevalent among athletes, and it can negatively affect physical performance. At the same time, most of the available data were obtained from untrained individuals of various ages, and published studies performed in athletes led to contradictory conclusions. Methods: This cohort prospective study examined the serum concentration of 25-hydroxycalciferol (25(OH)D) and its association with running speed and muscle power in 131 young football players (mean age 15.6 ± 2.4 years). Results: 25(OH)D levels were below reference in 42.8% (serum 25(OH)D <30 ng/mL) and above reference in 30.5% of the participants (serum 25(OH)D 61–130 ng/mL). A comparison of the results of 5, 15, and 30 m sprint tests and the standing long jump test found no statistically significant differences between the two groups. Athletes from the 25(OH)D-insufficient group were treated with 5000 IU cholecalciferol supplement daily for 60 days. After the treatment, the 25(OH)D concentration increased by 79.2% and was within reference in 84% of the treated athletes (serum 25(OH)D 30–60 ng/mL). Testing was repeated after the end of treatment, and a statistically significant increase in the results of the 5, 15, and 30 m sprint tests was observed (Cohen’s d was 0.46, 0.33, and 0.34, respectively), while the results of the standing long jump test remained unchanged. Body height, body weight, and lean body mass of the football players also increased. Conclusions: These findings indicate that there is likely no correlation between serum levels of 25(OH)D, muscle power, and running speed in young professional football players, and the changes observed post-treatment might have been caused by changes in the anthropometric parameters. During the study, all the anthropometric parameters changed, but the amount of lean body mass only correlated with the results of the 5 m sprint.

Background: The present study investigated the impact of competitive soccer on the short-term changes in isometric strength of the adductor muscle group during the competitive season. Methods:In this cohort study we evaluated the association between a serum marker of muscle damage [creatine phosphokinase (CPK)] and isometric strength of the adductor muscles of the hip in 30 professional football players (age: 26.7±2.9 years) during two seasons of the national top-level championship. Serum CPK level was determined the day before the match, 12-20, 36-48, 60-72 h after the match. The maximum voluntary isometric contraction force of the adductor muscles complex was determined immediately after having taken blood samples.Results: There was evidence of a statistically significant positive association between age, body mass index (BMI), percentage of body fat, and muscle strength, and between weight and muscle strength. There was evidence of a statistically significant negative association between the level of CPK and the maximum isometric strength of the adductors of soccer players. Changes in CPK levels were associated with the muscle strength recovery trend (P<0.001). The strength/CPK ratio at different time points had a U-shaped curve.Conclusions: Exercise induced muscle damage significantly affects the strength of the adductor muscle group of professional soccer players during the competitive period. The lower the CPK level, the greater the athletes' strength at a given time point. Also, the greater the decrease in CPK level, the greater the rate of strength restoration.
