Physiotherapists in Winchester treat many different conditions including the issues profiled below.

Muscle Fibre Types

Muscle has three main fibre types which are specialised for different functional abilities. Type 1 muscle fibres, also known as slow twitch fibres, have a good capillary supply and use a mostly aerobic energy system. Type 2 fibres use a non-aerobic energy system more typically and in general the proportion of Type 1 to Type 2 fibres is fixed genetically in an individual. Muscle cells don.t turn over like many other body cells, the muscle continues for the life of the person. Muscles get larger and stronger by the individual muscle cells gaining mass and the number of muscle cells does not change.

Muscles are very adaptive tissues and can respond to altered work demands very much more quickly than other tissues, enabling us to build up the ability to do something new in a short time. The way the muscles are exercised has strong effects on the way muscles adapt to the new stresses. If endurance training is performed, with lower weights and higher repetitions, the largest changes are in the Type 1 slow twitch fibres which exhibit increases in their blood supply and in the enzyme systems which deliver energy. This allows these muscle fibres to contract for longer periods without tiring.

Frozen Shoulder

Frozen shoulder is a somewhat mysterious condition which afflicts people mostly in their middle years and can give high levels of pain and disability which can last over several years. Onset of frozen shoulder is typically sudden and may follow a minor shoulder injury or even a tweak on some unaccustomed movement which may not seem relevant. The initial phase is of steadily increasing pain which can be very severe and badly interfere with sleep. During this phase the shoulder is very difficult to move and the patient needs strong analgesia to get some rest and function normally.

Once the acutely painful period has passed the shoulder begins to lose range of movement, particularly lateral rotation, the ability to rotate the upper arm bone outwards. As the pain gradually reduces slowly the stiffness of the shoulder increases until the arm is just very stiff without much in the way of pain. Overall the process can last two years or more until the shoulder loosens up although full range of motion may never be recovered. On examination lateral rotation and elevation will be severely limited and the patient will often lift the whole shoulder girdle in an attempt to raise the arm.
