When should you become active again after injury?
Starting active movements very importantly helps someone with an acute injury return to daily activities, aiding the body's processes to regain full muscle function and neuromuscular control.
Activity promotes and stimulates the repair and remodelling of injured tissue. After a brief rest period following an injury to allow the scar tissue to stabilise, the benefits of starting active movements include faster and more complete regeneration and the minimising of atrophy of surrounding tissue.
Activity naturally increases the fluid flow, blood and lymph supply and nerve signals from a region which work together to start the healing process more quickly and with better long-term results than with a period of inactivity. Getting back to activity prevents fibrous adhesions from having the opportunity to develop.
One week of immobilisation causes a 3-4% decrease in muscle strength every day. Starting rehabilitation 48 hours after injury reduces the interval from injury to pain-free recovery without increasing the risk of re-injury.
Although exercise induces hypoalgesia, deceasing sensitivity to painful stimuli, any pain, especially sharp pain will lead to the retearing of the damaged fibres and retriggers the neuromusclular response leading to more tension, which is why it is crucial to stay with the pain threshold, while keeping any movement as normal as possible.
During an injury phase, the body adapts to function as well as it can. Prolonged inactivity will make the central nervous system forget the normal movement prior to the injury and so it is important that it is reminded as soon as possible. Moving the affected area as much as possible and as soon as possible within the pain free range to start with, through the normal range of movement, for example bending and straightening the arm for a biceps injury will make sure the regeneration process is not delayed.
Delays caused by resting for too long rapidly reduces the strength in the tissues, making rehabilitation more difficult. Lack of use quickly loses neuromuscular function and this needs to be reactivated as quickly as possible to prevent delays in recovery. Neuromuscular mechanisms need to be kept active so they don’t ‘forget’ what they are doing. Lack of movement compromises the quality and control of movement.
Mobilisation as soon as possible after the injury should be gradual and progressive.
The stimulation of movement, especially in the early stages of healing, is a crucial part of recovery from injury.
