The exercise ball is an exercise treatment option for back pain sufferers.
It is designed to help or minimize further episodes of low back pain.
The exercise ball is effective in rehabilitation of the back because it strengthens and develops the core body muscles that help to stabilize the spine.
What happens over time is that the muscles you use to keep in balance on the ball become stronger and stronger.
You then build strength in important back muscles and abdominal muscles without knowing it.
They say that an it has an increased tendency to maintain a neutral spine position during exercise
In particular, many Swiss ball exercises are designed to bring movement to the spine in a controlled manner to help keep the discs nourished.
You can get them online or from physiotherapy departments but for someone already suffering from a bad back your first port of call should be to visit a GP for a referel to a Physiotherapist. You should NEVER try to do the exercises without seeing someone first.
