The Old Wisdom: Rest Is Best?
For decades, the standard advice for many injuries and post-surgical procedures was prolonged rest. The thinking was straightforward: an injured or repaired part of the body needed to be kept still to heal properly. This approach, known as immobilization,
was intended to prevent further damage and allow tissues to mend without disturbance. Patients were often told to wait weeks before beginning any form of rehabilitation. While rest is crucial in the immediate aftermath of trauma to control swelling and acute pain, we now know that waiting too long to start moving can create its own set of problems. Prolonged inactivity leads to muscle atrophy, where muscles weaken and shrink from disuse. Joints can become stiff, and scar tissue can form in a disorganized way that restricts motion and may lead to chronic pain.
The New Approach: The Power of Early Mobilisation
Modern medicine has seen a significant shift towards early mobilisation. This means introducing gentle, controlled movement much sooner in the healing process, often under the guidance of a physiotherapist. For many common surgeries, like ACL reconstruction or total knee replacements, physiotherapy can begin within days, not weeks. Even after a stroke, revised guidelines emphasize starting rehabilitation as soon as a patient is medically stable, sometimes within 24 to 48 hours. The goal is not to push through pain but to use therapeutic movement to guide the body's natural healing process. Early intervention helps improve blood flow, which delivers essential oxygen and nutrients to the healing tissues. It also prevents the joint stiffness and muscle weakness that come from being inactive.
The Benefits of an Early Start
Starting physiotherapy sooner offers a host of advantages. One of the most significant is a faster overall recovery. Patients who begin guided rehabilitation early often regain strength and mobility more quickly, allowing for a swifter return to daily activities. Early movement helps manage pain and reduce swelling by promoting circulation. It also lowers the risk of post-surgical complications like blood clots and infections, which are more common with prolonged bed rest. Furthermore, structured exercise helps ensure that scar tissue forms in a more flexible, organised manner, preserving joint function. There is a psychological benefit, too; taking an active role in recovery can give patients a sense of control and optimism, reducing the anxiety that often accompanies a long healing process.
Is It Always Safe to Start Early?
While the benefits are clear, “early” does not mean “aggressive” or immediate for every condition. The decision must always be guided by a medical professional. For certain injuries, such as unstable fractures or severe ligament tears with significant swelling, a period of rest and immobilization is still necessary to allow the initial healing phase to complete. Pushing the body too hard, too soon can disrupt healing tissues and worsen the injury. The key is that the rehabilitation is appropriate for the injury and its stage of healing. A physiotherapist will create a personalised plan that starts with very gentle range-of-motion exercises, muscle activation, and pain management techniques before progressing to more demanding strengthening and functional activities.
How to Take an Active Role in Your Recovery
As a patient, you are a key partner in your recovery. Before a planned surgery, you can have a conversation with your surgeon about what to expect post-operatively and ask about their protocol for physiotherapy. This is sometimes called 'prehabilitation', and preparing your body for surgery can improve outcomes. After an injury or operation, don't hesitate to ask your doctor when it is safe to consult a physiotherapist. Be clear about your goals, whether it's returning to a sport, playing with your children, or simply walking without pain. A physiotherapist will work in coordination with your doctor to create a tailored plan that respects your body's healing timeline while actively promoting a stronger, faster recovery.
