Physiotherapist, Dr Sian MacRae, decided to find out during her PhD at Kings’s College London if 'rocker sole' footwear could improve back pain and disability seeing that patients were always asking her questions on this particular subject.The questionnaire revealed:
In the study, in the journal Spine, 115 people with chronic lower back pain were asked to wear rocker sole shoes or normal trainers for at least two hours a day while standing and walking.
They also attended an exercise and education programme once a week for four weeks and wore their shoes during these sessions. After six weeks, six months and then one year, the participants were assessed using a disability questionnaire.At the end of the study, researchers calculated that people in the trainer-wearing group experienced a larger reduction in disability than those in the rocker sole group.
After six months, 53% of the trainer group showed a small improvement in their back mobility compared to 31% of the rocker sole group.
For the 59 people who said their back pain was aggravated by standing and walking at the start of the study, those in the trainers group experienced a greater reduction in disability after one year than those in the rocker sole group.Shoes with curved unstable soles are no better than traditional trainers for reducing lower back pain, suggests a study from King's College London.
But previously published research has shown that the shoes can have a positive impact on posture, back and joint pain. Medical professionals are known to regularly recommend the shoes.
The study also said normal trainers may be more beneficial for back pain brought on by standing or walking. Shoes with an unstable curved sole are often sold as being able to help increase muscle activity, reduce lower back pain and improve posture and balance.
Dr MacRae said: "On the basis of the findings of this randomised clinical trial, clinicians should be confident in advising patients with chronic lower back pain that wearing either rocker sole shoes or trainers may offer similar outcomes in disability and pain."However, if a patient reports lower back pain when standing or walking, it may be more beneficial to wear trainers than rocker sole shoes."
