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

Spinal Posture

Spinal posture can mean two main things, one being the shape and orientation of the curves in the spine and two being the angle that the whole spine is aligned to the vertical. The minimum of muscle activity occurs when the trunk is balanced directly above the pelvis and any deviation from this requires muscle activity to increase to maintain position. As the main moving muscles of the spine are orientated lengthways like the spine itself, when they contract they generate significant compression forces through the spine. Contraction of these muscles in easy standing or sitting still generates forces through the lumbar spine that are twice the body weight above the area.

In sitting it makes little difference to the degree of muscle activity whether the lumbar spine is held arched to some degree (lumbar lordosis) or flexed (bent), the key point is whether the spine is vertically aligned or not. So leaning back with a lordosis or forwards with a flexed spine both generate high muscle forces, whilst sitting upright in either posture does not. Sitting positions all flex the lumbar spine, with the lower two lumbar levels being significantly flexed in these postures, even to the maximum of their movement.

Environmental Risks for Low Back Pain

The risks of low back pain are well known to be connected with high risk activities such as lifting heavy objects from the floor whilst twisted or doing activities requiring quick bending and twisting. A sudden and unplanned occurrence of having to exert high levels of muscle power quickly is also risky for developing low back problems. The physical demands of work such as lifting, twisting, bending and vibration are all risk factors for developing back trouble and in worsening already existing cases of back trouble. There is not a clear connection between work and back trouble although work stresses, if prolonged, can cause episodes or back pain or prolong already existing ones.

The reasons for not being able to work and for developing disability from a back pain problem are more closely related to complex factors of a psychosocial nature which are both individual and work related. Factors relating to sport have been contradictory in the research literature but activities which demand heavy loads such as gymnastics and weight lifting are associated with a higher risk of disc degeneration which could lead to symptoms in time. Spinal tissues may be affected adversely both by too little activity and by too much.
