DO I REALLY NEED?

LumbaCurve for lower back pain, £79, lumbacurve.com THIS hard plastic device, the size of a small cushion, is designed to relieve pain by stretching out your back: you lie on the floor and slide it under your lower back.

EXPERT VERDICT: This could do a lot for lower back pain, says Dr Andrew Martin, a chiropractor and founder of the ActiveBacks clinic in London.

‘It helps you stretch in a way you wouldn’t otherwise be able to,’ he says.

‘People get pain in their lower back when the natural slight ‘c’ shape of the lumbar spine becomes straightened by bad posture or sitting in an office chair. Bending back over this curved device would help restore the natural curvature and ease pressure and pain.

‘ It is similar to another product I recommend called Back Magic by BodiTec, which would be more suited to those stretching for the first time because it’s less curved.’

If you feel pain in your leg, stop: it may be a trapped nerve and you should seek help.
