Physiotherapists in Dorchester 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.

Neck Posture

The head is a large and heavy object balanced on top of a slender column of bone and ligaments which is known as the neck. Postural neck pain is very common as our mainly sedentary lifestyles mean that we spend long periods in one position often with our necks held in less than optimal postures. Gravity pushes us down all the time and the neck tends to move forward as the lower neck flexes for us to look down at books or computers. As our head is now looking downwards we don't want to look at the floor all the time so we tilt the head back up, extending the upper neck.

This position, when held long term, can lead to the head stuck forward posture and a .dowager's hump., a prominent bony area at the base of the back of the neck. This can lead to neck strain both at the top and bottom of the neck, causing neck and shoulder pain lower down and neck and head pain higher up. The head forward posture forces the neck muscles and the upper trapezius to work harder than normal to hold the head up in its abnormal position.
