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

Discs and Height

Physical activities change the nature of the intervertebral discs throughout the day and night. The volume and the height of discs can change by up to twenty percent, with a person.s height varying by anything from fifteen to twenty five millimetres. Most of the change in height happens during the first hour after getting up as the body weight loading is applied to the spine. During the night the opposite happens with the disc being unloaded so it sucks in water from the tissue around it until it reaches a balance of pressures on both sides.

This daily cycle of pressure variation changes the water content of the disc regularly and may be part of the explanation as to why back pain sufferers have more pain in the mornings due to the increased tension present in the disc complex. Resting or performing heavy work can cause changes in the hydration of the disc, carrying a twenty kilogram backpack for three hours has been shown to reduce the volume of the discs by 4.5 percent. The amount of water content in the disc does not achieve a specific resting level; it depends on how much loading is going on and for how long.

Knee Ligament Injuries

Knee injuries are extremely common and a routine part of sporting activities of many kinds, especially in younger people. The knee is a large hinge type of joint connected by powerful ligaments but because of the joint.s position in the middle of a long lever (the leg) it is vulnerable to high levels of force during movement. Physiotherapists routinely diagnose and treat ligamentous injuries and rehabilitate patients back to their functional goal. A common injury is a strain of the medial collateral ligament when a force is applied to the outside of the knee when the foot is on the ground, pushing the knee inwards and opening out the joint on the inside.

Typically the knee will swell over the next 12 hours or so and be painful over the inside of the joint, sometimes making it difficult to walk easily. Treatment is to immobilise the knee in a brace or plaster of Paris for a shorter or longer period of time, then get the knee moving so that it does not lose range of movement. The ligament is under tension when the knee is straight so the physio will concentrate on restoring the ability of the muscles to fully extend the knee.
