Association between Neck/Shoulder Pain and Trapezius Muscle Tenderness in Office Workers
Background. Neck/shoulder pain is a common musculoskeletal disorder among adults. The pain is often assumed to be related to muscular tenderness rather than serious chronic disease. Aim. To determine the association between neck/shoulder pain intensity and trapezius muscle tenderness in office workers. Methods. 653 employees from two large office workplaces in Copenhagen, Denmark, replied to a questionnaire on health and working conditions (mean: age 43 years, body mass index 24 kg·m−2, computer use 90% of work time, 73% women). Respondents rated intensity of neck/shoulder pain during the previous three months on a scale of 0–10 and palpable tenderness of the upper trapezius muscle on a sca…
The Female Handball Player
Female hormones fluctuate in concentrations during the menstrual cycle. This has triggered speculations among athletes, coaches, as well as researchers about the hormonal changes that lead to variations in athletic performance and adaptation to training. Many athletes, as in the general population, use oral contraceptives. This has raised questions concerning the suppression of the endogenous circulating female hormones and if the administration of synthetic hormones may have negative impact on athletic performance and training adaptations – or the opposite.
Effect of Brief Daily Resistance Training on Occupational Neck/Shoulder Muscle Activity in Office Workers with Chronic Pain: Randomized Controlled Trial
Purpose. This study investigates the acute and longitudinal effects of resistance training on occupational muscle activity in office workers with chronic pain.Methods. 30 female office workers with chronic neck and shoulder pain participated for 10 weeks in high-intensity elastic resistance training for 2 minutes per day (n=15) or in control receiving weekly email-based information on general health (n=15). Electromyography (EMG) from the splenius and upper trapezius was recorded during a normal workday.Results. Adherence to training and control interventions were 86% and 89%, respectively. Compared with control, training increased isometric muscle strength 6% (P<0.05) and decreased neck…
