Hamstring Muscles: From 1 Different Sources


A group of muscles at the back of the thigh. The upper ends of the hamstring muscles are attached by tendons to the pelvis; the lower ends are attached by tendons called hamstrings to the tibia and fibula. The hamstring muscles bend the knee and swing the leg backwards from the thigh. Tearing of the hamstring muscles is common in sports. Repeated strenuous exercise may sprain the muscles (see overuse injury).

Muscles, Disorders Of

Compression syndrome The tense, painful state of muscles induced by excessive accumulation of INTERSTITIAL ?uid in them, following unusual exercise. This condition is more liable to occur in the muscles at the front of the shin, because they lie within a tight fascial membrane: here the syndrome is known as the anterior tibial syndrome (‘shin splints’). Prevention consists of always keeping ?t and in training for the amount of exercise to be undertaken. Equally important is what is known in sporting circles as ‘warming down’: i.e., at the end of training or a game, exercise should be gradually tailed o?. Treatment consists of elevation of the affected limb, compression of it by compression bandages, with ample exercise of the limb within the bandage, and massage. In more severe cases DIURETICS may be given. Occasionally surgical decompression may be necessary.

Cramp Painful spasm of a muscle usually caused by excessive and prolonged contraction of the muscle ?bres. Cramps are common, especially among sportsmen and women, normally lasting a short time. The condition usually occurs during or immediately following exercise as a result of a build-up of LACTIC ACID and other chemical by-products in the muscles

– caused by the muscular e?orts. Cramps may occur more frequently, especially at night, in people with poor circulation, when the blood is unable to remove the lactic acid from the muscles quickly enough.

Repetitive movements such as writing (writer’s cramp) or operating a keyboard can cause cramp. Resting muscles may suffer cramp if a person sits or lies in an awkward position which limits local blood supply to them. Profuse sweating as a result of fever or hot weather can also cause cramp in resting muscle, because the victim has lost sodium salts in the sweat; this disturbs the biochemical balance in muscle tissue.

Treatment is to massage and stretch the affected muscle – for example, cramp in the calf muscle may be relieved by pulling the toes on the affected leg towards the knee. Persistent night cramps sometimes respond to treatment with a drug containing CALCIUM or QUININE. If cramp persists for an hour or more, the person should seek medical advice, as there may be a serious cause such as a blood clot impeding the blood supply to the area affected.

Dystrophy See myopathy below.

In?ammation (myositis) of various types may occur. As the result of injury, an ABSCESS may develop, although wounds affecting muscle generally heal well. A growth due to SYPHILIS, known as a gumma, sometimes forms a hard, almost painless swelling in a muscle. Rheumatism is a vague term traditionally used to de?ne intermittent and often migratory discomfort, sti?ness or pain in muscles and joints with no obvious cause. The most common form of myositis is the result of immunological damage as a result of autoimmune disease. Because it affects many muscles it is called POLYMYOSITIS.

Myasthenia (see MYASTHENIA GRAVIS) is muscle weakness due to a defect of neuromuscular conduction.

Myopathy is a term applied to an acquired or developmental defect in certain muscles. It is not a neurological disease, and should be distinguished from neuropathic conditions (see NEUROPATHY) such as MOTOR NEURONE DISEASE (MND), which tend to affect the distal limb muscles. The main subdivisions are genetically determined, congenital, metabolic, drug-induced, and myopathy (often in?ammatory) secondary to a distant carcinoma. Progressive muscular dystrophy is characterised by symmetrical wasting and weakness, the muscle ?bres being largely replaced by fatty and ?brous tissue, with no sensory loss. Inheritance may take several forms, thus affecting the sex and age of victims.

The commonest type is DUCHENNE MUSCULAR DYSTROPHY, which is inherited as a sex-linked disorder. It nearly always occurs in boys.

Symptoms There are three chief types of myopathy. The commonest, known as pseudohypertrophic muscular dystrophy, affects particularly the upper part of the lower limbs of children. The muscles of the buttocks, thighs and calves seem excessively well developed, but nevertheless the child is clumsy, weak on his legs, and has di?culty in picking himself up when he falls. In another form of the disease, which begins a little later, as a rule at about the age of 14, the muscles of the upper arm are ?rst affected, and those of the spine and lower limbs become weak later on. In a third type, which begins at about this age, the muscles of the face, along with certain of the shoulder and upper arm muscles, show the ?rst signs of wasting. All the forms have this in common: that the affected muscles grow weaker until their power to contract is quite lost. In the ?rst form, the patients seldom reach the age of 20, falling victims to some disease which, to ordinary people, would not be serious. In the other forms the wasting, after progressing to a certain extent, often remains stationary for the rest of life. Myopathy may also be acquired when it is the result of disease such as thyrotoxicosis (see under THYROID GLAND, DISEASES OF), osteomalacia (see under BONE, DISORDERS OF) and CUSHING’S DISEASE, and the myopathy resolves when the primary disease is treated.

Treatment Some myopathies may be the result of in?ammation or arise from an endocrine or metabolic abnormality. Treatment of these is the treatment of the cause, with supportive physiotherapy and any necessary physical aids while the patient is recovering. Treatment for the hereditary myopathies is supportive since, at present, there is no cure – although developments in gene research raise the possibility of future treatment. Physiotherapy, physical aids, counselling and support groups may all be helpful in caring for these patients.

The education and management of these children raise many diffculties. Much help in dealing with these problems can be obtained from Muscular Dystrophy Campaign.

Myositis ossi?cans, or deposition of bone in muscles, may be congenital or acquired. The congenital form, which is rare, ?rst manifests itself as painful swellings in the muscles. These gradually harden and extend until the child is encased in a rigid sheet. There is no e?ective treatment and the outcome is fatal.

The acquired form is a result of a direct blow on muscle, most commonly on the front of the thigh. The condition should be suspected whenever there is severe pain and swelling following a direct blow over muscle. The diagnosis is con?rmed by hardening of the swelling. Treatment consists of short-wave DIATHERMY with gentle active movements. Recovery is usually complete.

Pain, quite apart from any in?ammation or injury, may be experienced on exertion. This type of pain, known as MYALGIA, tends to occur in un?t individuals and is relieved by rest and physiotherapy.

Parasites sometimes lodge in the muscles, the most common being Trichinella spiralis, producing the disease known as TRICHINOSIS (trichiniasis).

Rupture of a muscle may occur, without any external wound, as the result of a spasmodic e?ort. It may tear the muscle right across – as sometimes happens to the feeble plantaris muscle in running and leaping – or part of the muscle may be driven through its ?brous envelope, forming a HERNIA of the muscle. The severe pain experienced in many cases of LUMBAGO is due to tearing of one of the muscles in the back. These conditions are usually relieved by rest and massage. Partial muscle tears, such as occur in sport, require more energetic treatment: in the early stages this consists of the application of an ice or cold-water pack, ?rm compression, elevation of the affected limb, rest for a day or so and then gradual mobilisation (see SPORTS MEDICINE).

Tumours occur occasionally, the most common being ?broid, fatty, and sarcomatous growths.

Wasting of muscles sometimes occurs as a symptom of disease in other organs: for example, damage to the nervous system, as in poliomyelitis or in the disease known as progressive muscular atrophy. (See PARALYSIS.)... muscles, disorders of

Calf Muscles

The muscles extending from the back of the knee to the heel.

The gastrocnemius muscle starts behind the knee and forms the bulky part of the calf; under it is the soleus muscle which starts at the back of the tibia (shin).

The 2 muscles join to form the Achilles tendon, which connects them to the heel.

Contraction of the calf muscles pulls the heel up and is important in walking, running, and jumping.

Pain in these muscles occurs because of cramp, sciatica, or, more rarely, deep vein thrombosis.

The calf muscles may be affected by claudication (pain caused by walking and relieved by rest).... calf muscles

Accessory Muscles

muscles of the shoulder girdle and chest wall that (in addition to the intercostal muscles and the diaphragm) are utilized during *respiratory distress to help the flow of air in and out of the lungs. Use of these muscles can be a sign of the degree of difficulty that the patient is in, for example in cases of asthma or *airway obstruction.... accessory muscles

Hamstring
