Hypermobility syndrome is a condition that features joints that easily move beyond the normal range expected for a particular joint. Hypermobility is also known as “double-jointness”. This particular disorder has an unknown discovery date and founder. The causes of hypermobility are family history: disorder is inherited‚ bone structure‚ muscle structure and sense of proprioception which is knowing how far you are able to stretch. Genes that are responsible for the production of collagen are suspected

Muscle Strain Overview- Muscle strain‚ also termed as muscle tear and muscle pull is related to the muscle damage and its attached tendons. It occurs when you give excessive pressure on muscles during performing daily life activities like during sports or heavy weight lifting.it can be in the form of tearing of the fibres of your muscles and attaching tendons. In addition to this it also affects small blood vessels which leads to bleeding‚ bruising and pain. Causes- A severe muscle strain occurs

Having injuries can hinder the ability to do every day activity‚ hobbies or goal. The appropriate care and prevention with specific rehabilitation treatment could increase the likelihood of returning the injured area to 100%. In this research paper‚ specific symptoms‚ types of injuries‚ treatment‚ rehabilitation as well as exercise will be covered for chronic shoulder dislocation. Chronic shoulder dislocation is a described as the glenohumeral joint that has remained dislocated fro several days

good and common example of a soft tissue injury would be pulling or tearing your hamstring. The hamstring is located at the bag of your leg and runs from the back of your knee to just below the gluteus Maximus. This injury will occur when the muscle is overstretched and is common in most sports but especially football and sprinting due to the amount of work your legs go through. Soft tissue includes tendons‚ ligaments‚ fascia‚ skin‚ fibrous tissues‚ fat‚ and synovial membranes‚ which are connective

INTRODUCTION I am going to explain the voluntary muscle the different types of muscle fibre including slow twitch fast twitch‚including how their properties are influenced by their reliance on aerobic and anaerobic energy sources. Skeletal muscle is made up of bundles of individual muscle fibres called myocytes. Each myocyte contains many myofibrils‚ which are strands of proteins (actin and myosin) that can grab on to each other and pull. This shortens the muscle and causes muscle contraction

1.) What muscle did the winging of the scapula suggest to be paralysed? Why does this sign occur? The muscle that was suggested to be paralysed due to the winging of the scapula is the Serratus Anterior muscle. The Serratus Anterior muscle’s origin is situated on the external surface of the lateral surfaces of the upper 8 to 9 ribs (ribs 1 to 8) while the insertion of this muscle is located on the costal surface of the medial border of the scapula. Therefore‚ this muscle is innervated by the long
