The Effect of corrective exercises on the functional condition of the upper limb of sedentary workers

Abstract

Introduction. An increasing number of people spend more time in sedentary work, which affects musculoskeletal disorders, tension and shortening of muscles, decreased muscle strength and amplitude, increased intervertebral disc compression, deteriorating posture, neck and shoulder complex pain are the most common of sedentary musculoskeletal disorders (1). Physical activity is an effective intervention method in reducing the progression of most chronic diseases but also has positive effect on the muscles and composition of the human body, it also reduces development of the psycho-emotional conditions in humans (2). Research aim: To evaluate the effect of corrective exercises on the functional condition of the upper limb of sedentary workers. Research methods and organization. The study research was approved by Lithuanian University of Health Science Bioethics Center (BEC-SR(M)-172). The study was initiated and conducted on 2021.07.19 – 2021.08.30 the home of the subjects. Participants of the study were gathered from different workplaces which involves sedentary job. All the participants signed the informed consent form before taking part in this study. A total of 21 participated in the study 9 men, 12 women. In this study involved people aged 40- 50 working in a sedentary job, who felt pain in the neck, shoulders, decreased muscle strength in upper extremities, amplitude, impaired functional movements. Age of all subjects was 46.62 ± 2.69 years. Age mean of the men was 46.33 ± 2.40 years, and the mean age of the women was 46.83± 2.98 years. Selection criteria: voluntary consent to participate in the study; feeling of discomfort in the shoulders or neck; decreased amplitude of movements of the joints of the upper extremities; persons spending at least 4 to 5 hours a day sedentary position. Exclusion criteria: pain intensity not exceeding 6 points; engaged in professional sports; with less than 2 years of job experience. SAS was used to evaluate pain intensity; DASH was used to determine the degree of shoulder pain and dysfunction. Statistical analysis was performed using “IMB SPSS Statistics 27.0” software package. A non-parametric Wilcoxon test was used to compare the two dependent samples. Data were presented as the median (me), minimal (min), maximal (max) and the mean– me (min; max; mean). The significance level was set at p<0.05. Results. The median of the woman’s pain intensity at the beginning of research was 3.5 (2– 6; 3.7) points, men’s 4 (2– 6; 3.9) points. After physiotherapy, women’s pain intensity was 2 (0– 3; 1.5) points, men’s 2 (0– 3; 1.7). Examining the obtained data before and after physiotherapy statistically significant decrease intensity of pain was found in women (Z=–3.166; p=0.002) and men (Z=– 2.810,..[…].
