Objective To determine the short-term effectiveness of thoracic manipulation when compared to sham manipulation for individuals with low back pain (LBP). Design Randomized controlled trial. Methods Patients with LBP were stratified based on symptom duration and randomly assigned to a thoracic manipulation or sham manipulation treatment group. Groups received 3 visits that included manipulation or sham manipulation, core stabilization exercises, and patient education. Factorial repeated-measures analysis of variance and multiple regression were performed for pain, disability, and fear avoidance. The Mann-Whitney U test was used to analyze patient-perceived improvement, via the global rating of change scale, at follow-up. Results Ninety participants completed the study (mean ± SD age, 38 ± 11.5 years; 70% female; 72% with chronic LBP). The overall group-by-time interaction was not significant for the Modified Oswestry Disability Questionnaire, numeric pain-rating scale, and Fear-Avoidance Beliefs Questionnaire outcomes. The global rating of change scale was not significantly different between groups. Conclusion Three sessions of thoracic manipulation, education, and exercise did not result in improved outcomes when compared to a sham manipulation, education, and exercise in individuals with chronic LBP. Future studies are needed to identify the most effective management strategies for the treatment of LBP. Level of Evidence Therapy, level 1b. J Orthop Sports Phys Ther 2020;50(1):24–32.

Published: December 2019

The work describes the production of complex fertilizers of prolonged effect on the basis of acid-free processing of phosphate rock of the Vyatka-Kama Deposit. The authors investigated the influence of chemical composition of salts and mass ratio between salt and phosphate components on the degree of activation of the phosphorite flour of the Vyatka-Kama Deposit (VKPF) during its treatment with solutions and suspensions of nitrogen-containing mineral salts and potassium chloride. It has been determined that the content of available form of P2O5 in phosphorite increases by 1.5-2 times, and the greatest activating effect is provided by ammonium salts. The use of preliminary mechanical activation of VKPF, in the method investigated, provides the increase in the content of available form of P2O5 by 11–13 %. The mechanism of interaction of the main minerals of phosphorite with salt additives (ammonium sulfate, ammonium nitrate, ammonium chloride, carbamide, potassium chloride) is proposed. The dynamics of changes in the content of ammonium nitrogen in fertilizer compositions at each stage of the process has been determined. The method for producing complex fertilizers based on phosphorite flour of the Vyatka-Kama Deposit has been developed and patented.
