Textbook Of Work Physiology Physiological Bases Of Exercise

Synopsis There is a growing body of literature associating abnormal scapular positions and motions, and, to a lesser degree, clavicular kinematics with a variety of shoulder pathologies. The purpose of this manuscript is to (1) review the normal kinematics of the scapula and clavicle during arm elevation, (2) review the evidence for abnormal scapular and clavicular kinematics in glenohumeral joint pathologies, (3) review potential biomechanical implications and mechanisms of these kinematic alterations, and (4) relate these biomechanical factors to considerations in the patient management process for these disorders. There is evidence of scapular kinematic alterations associated with shoulder impingement, rotator cuff tendinopathy, rotator cuff tears, glenohumeral instability, adhesive capsulitis, and stiff shoulders. There is also evidence for altered muscle activation in these patient populations, particularly, reduced serratus anterior and increased upper trapezius activation. Scapular kinematic altera...

The association of scapular kinematics and glenohumeral joint pathologies

BackgroundStrengthening exercises for the scapular muscles are used in the treatment of scapulothoracic dysfunction related to shoulder injury. In view of the intermuscular and intramuscular imbalances often established in these patients, exercises promoting lower trapezius (LT), middle trapezius (MT), and serratus anterior (SA) activation with minimal activity in the upper trapezius (UT) are recommended.HypothesisOf 12 commonly used trapezius strengthening exercises, a selection can be performed for muscle balance rehabilitation, based on a low UT/LT, UT/MT, or UT/SA muscle ratio.Study DesignControlled laboratory study.MethodsElectromyographic activity of the 3 trapezius parts and the SA was measured in 45 healthy subjects performing 12 commonly described scapular exercises, using surface electromyography.ResultsFor each intramuscular trapezius ratio (UT/LT, UT/MT), 3 exercises were selected for restoration of muscle balance. The exercises side-lying external rotation, side-lying forward flexion, prone h...

Rehabilitation of Scapular Muscle Balance Which Exercises to Prescribe

Background and Objective: As Light Emitting Diode (LED) devices are commercially introduced as an alternative for Low Level Laser (LLL) Therapy, the ability of LED in influencing wound healing processes at cellular level was examined. Study Design/Materials and Methods: Cultured fibroblasts were treated in a controlled, randomized manner, during three consecutive days, either with an infrared LLL or with a LED light source emitting several wavelengths (950 nm, 660 nm and 570 nm) and respective power outputs. Treatment duration varied in relation to varying surface energy densities (radiant exposures). Results: Statistical analysis revealed a higher rate of proliferation (p ≤ 0.001) in all irradiated cultures in comparison with the controls. Green light yielded a significantly higher number of cells, than red (p ≤ 0.001) and infrared LED light (p ≤ 0.001) and than the cultures irradiated with the LLL (p ≤ 0.001); the red probe provided a higher increase (p ≤ 0.001) than the infrared LED probe and than the LLL source. Conclusion: LED and LLL irradiation resulted in an increased fibroblast proliferation in vitro. This study therefore postulates possible stimulatory effects on wound healing in vivo at the applied dosimetric parameters.

Increased fibroblast proliferation induced by light emitting diode and low power laser irradiation.

Work related neck disorders are common problems in office workers, especially among those who are intensive computer users. It is generally agreed that the etiology of work related neck disorders is multidimensional which is associated with, and influenced by, a complex array of individual, physical and psychosocial factors. The aim of the current study was to estimate the one-year prevalence of neck pain among office workers and to determine which physical, psychological and individual factors are associated with these prevalences. Five hundred and twelve office workers were studied. Information was collected by an online questionnaire. Self-reported neck pain during the preceding 12 months was regarded as a dependent variable, whereas different individual, work-related physical and psychosocial factors were studied as independent variables. The 12 month prevalences of neck pain in office workers was 45.5%. Multivariate analysis revealed that women had an almost two-fold risk compared with men (OR = 1.95, 95% CI 1.22-3.13). The odds ratio for age indicates that persons older than 30 years have 2.61 times more chance of having neck pain than younger individuals (OR = 2.61, 95% CI 1.32-3.47). Being physically active decreases the likelihood of having neck pain (OR = 1.85, 95% CI 1.14-2.99). Significant associations were found between neck pain and often holding the neck in a forward bent posture for a prolonged time (OR = 2.01, 95% CI 1.20-3.38), often sitting for a prolonged time (OR = 2.06, 95% CI 1.17-3.62) and often making the same movements per minute (OR = 1.63, 95% CI 1.02-2.60). Mental tiredness at the end of the workday (OR = 2.05, 95% CI 1.29-3.26) and shortage of personnel (OR = 1.71, 95% CI 1.06-2.76) are significantly associated with neck pain. The results of this study indicate that physical and psychosocial work factors, as well as individual variables, are associated with the frequency of neck pain. These association patterns suggest also opportunities for intervention strategies in order to stimulate an ergonomic work place setting and increase a positive psychosocial work environment.

Individual and work related risk factors for neck pain among office workers: a cross sectional study

Central sensitization in fibromyalgia? A systematic review on structural and functional brain MRI.

The scapula functions as a bridge between the shoulder complex and the cervical spine and plays a very important role in providing both mobility and stability of the neck/shoulder region. The association between abnormal scapular positions and motions and glenohumeral joint pathology has been well established in the literature, whereas studies investigating the relationship between neck pain and scapular dysfunction have only recently begun to emerge. Although several authors have emphasised the relevance of restoring normal scapular kinematics through exercise and manual therapy techniques, overall scapular rehabilitation guidelines decent for both patients with shoulder pain as well as patients with neck problems are lacking. The purpose of this paper is to provide a science-based clinical reasoning algorithm with practical guidelines for the rehabilitation of scapular dyskinesis in patients with chronic complaints in the upper quadrant.
