Back in Action offers advice on all aspects of back pain and treatments that are available for it in an easy-to-read question-and-answer format. Clear line illustrations make explanations even easier to understand. Contrary to popular opinion, well-known physiotherapist Sarah Key maintains that most back pain is not caused by disc problems, but simply by joint stiffness. Manual manipulation reactivates the joints and improves flexibility, according to Key, which means that treatment using the hands is the most successful in relieving pain. Key's 'hands-on' method has put thousands of grateful patients back in action.
