Lead researcher Professor Debbie Sharp said using the Alexander technique should provide help to most people with back pain.
She added: "Lessons in the Alexander technique offer an individualised approach to develop skills that help people recognise, understand, and avoid poor habits affecting postural tone and neuromuscular coordination.
"It can potentially reduce back pain by limiting muscle spasm, strengthening postural muscles, improving coordination and flexibility, and decompressing the spine."
Dries Hettinga, researcher manager for Back Care, a charity which offers support and advice to people with back pain, said: "There is little evidence available about the effectiveness of the Alexander technique so this research is welcome.
"The Alexander technique is something we do recommend and the feedback we have got is good.
"But I would say that it may not be effective for everyone. Back pain is different for each person and you often need a combination of things to help relieve it."
