Muscle Assessment in Women Who Have Undergone Roux-en-Y Gastric Bypass Surgery

2016-06-23 19:08:22 | BioPortfolio


The purpose of this study is to assess muscle function in women at least two years after being submitted to Roux-en-Y Gastric Bypass Surgery and compare with a control group


Obesity is a public health problem globally. According to the World Health Organization (WHO) estimated are 600 million obese worldwide and according to National Health Survey 2010 in Chile 67% of the population suffers from some degree of overweight having approximately 300,000 morbidly obese.

The first-line treatment for obesity is diet, exercise and cognitive behavioral therapy, however, these interventions are not effective enough to control long-term obesity, and so bariatric surgery is currently the treatment of choice to control morbid obesity.

Overall, after bariatric surgery, most patients lose on average 60% of excess weight and improve their comorbidities during the first postoperative year, however, the long term effects of this weight reduction are not known in detail regarding body composition and muscle function.

The aim of this study is to assess muscle function measured by hand grip strength test in women at least 2 years after bariatric surgery (Roux-en-Y Gastric Bypass) and to compare with control group.

Medical and Biotech [MESH] Definitions

The amount of force generated by MUSCLE CONTRACTION. Muscle strength can be measured during isometric, isotonic, or isokinetic contraction, either manually or using a device such as a MUSCLE STRENGTH DYNAMOMETER.

A device that measures MUSCLE STRENGTH during muscle contraction, such as gripping, pushing, and pulling. It is used to evaluate the health status of muscle in sports medicine or physical therapy.

A general term most often used to describe severe or complete loss of muscle strength due to motor system disease from the level of the cerebral cortex to the muscle fiber. This term may also occasionally refer to a loss of sensory function. (From Adams et al., Principles of Neurology, 6th ed, p45)

An operation that uses stimulated latissimus dorsi muscle (SKELETAL MUSCLE VENTRICLE) to assist cardiac function. The latissimus dorsi muscle is mobilized from the chest wall and moved into the thorax through the bed of the resected 2nd or 3rd rib. The muscle is then wrapped around the left and right ventricles and stimulated to contract during cardiac systole by means of an implanted burst-stimulator. (Stedman, 26th ed)

Thick triangular muscle in the SHOULDER whose function is to abduct, flex, and extend the arm. It is a common site of INTRAMUSCULAR INJECTIONS.
