When Should You Start Rehabilitation After an Injury ? What the Research Says.
One of the most common questions after an injury is:
“When should I start with rehabilitation?”
May people assume they should wait until the pain and swelling have completely disappeared before exercising again. In many cases that is not necessary.
Current sport-medicine research increasingly supports ealy, appropriate rehabilitation rather than prolonged complete rest. However, there is an important distinction:
Early rehabilitation does not mean immediately training the injured area hard.
It means introducing the right amount of movement and load at the right stage of healing.
The first step: Make sure the injure is safe to rehabilitate.
Before worrying about exercises, the injury needs to be appropriately assessed. Some injuries require protection, imaging, immobilisation, surgery or further medical investigation before exercise should begin.
This may include suspected fractures, dislocations, significant ligament injuries, tendon ruptures or injuries associated with severe swelling, deformity, neurological symptoms an inability to use the limb normally.
Once serious pathology have been excluded and the injury is medically appropriate for rehabilitation, the goal is normally not prolonged complete rest. Instead, rehabilitation gradually begins.
Why Do We Want to Start Rehabilitation Early?
When an injured muscle, tendon or joint is completely unloaded for too long, the body starts losing capacity.
Strength decreases.
Movement becomes restricted.
Confidence decreases.
Balance and coordination can deteriorate.
The injured tissue also eventually needs load in order to adapt and become strong enough for normal life or sport again. This is why modern rehabilitation focuses on finding the balance between:
Protecting the injured tissue and progressively exposing it to appropriate movement and load.
What Happens During the First Few Days?
Immediately after a soft-tissue injury, some protection may be necessary. The PEACH & LOVE approach described in the British Journal of Sports Medicine recommends protecting or reducing load during approximately the first 1-3 days when necessary, while avoiding unnecessary prolonged rest.
After the initial protective period, movement and exercise are gradually introduced according to symptoms and tissue tolerance. The goal is not to “push through” the injury. The goal is to give the body a stimulus it can successfully tolerance.
Rehabilitation Should Progress With the Injury.
A useful way to think about rehabilitation is a series of stages.
Stage 1 - Protect and Restore Movement.
Early goals may include:
Reducing excessive pain and swelling.
Regaining comfortable movement.
Maintraining movement in the surrounding joints.
Beginning gentle muscle activation.
Maintaining as much normal activity as safely possible.
At this point, rehabilitation may look extremely simple. A small amount of movement can still be rehabilitation.
Stage 2 - Restore Strength.
As symptoms settle and movement improves, exercise become progressively more challenging. The goal is to rebuild the capacity that was lost after the injury. Depending on the injury, this may include:
Isometric exercises.
Resistance exercises.
Balance training.
Range-of-motion work.
Movement training.
The important word is progressive. The body adapt when it is gradually exposed to greater demands.
Stage 3 - Restore function.
Being pain-free is not the same as being fully recovered. A runner needs to tolerate running. A rugby player needs to sprint, accelerate, decelerate and change direction.
A person returning to work may need to lift, carry or remain on their feet for long periods. Rehabilitation therefore has to gradually become more similar to the activity the person wants to return to.
Stage 4 - Return to Performance.
For athletes, rehabilitation should eventually prepare the body for the actual demands of sport. This may include:
Running.
Jumping and landing.
Acceleration and deceleration.
Change of direction.
Strength and power development.
Sport-specific conditioning.
Return-to-play testing.
The final question should not simply be: “How many weeks has it been?”
It should be: “Has this person regained the physical capacity required for what they want to return to?”
What Does the Research Say About Starting Early?
There is good evidence that appropriate early rehabilitation can improve recovery in certain musculoskeletal injuries.
One randomized study investigated athletes with significant thighb of calf muscle strains. One group began rehabilitation 2 days after injury. The other group began 9 days after injury.
The athletes who began rehabilitation earlier returned to sport in a median of approximately 62.5 days, compared with approximately 83 days in the delayed group. That is roughly three weeks faster.
Importantly, the study did not demonstrate a significant increase in reinjury from starting earlier. This does not mean every injury should begin the same programme after two days. It demonstrates something much more important. Unnecessary delay is not always protection.
A Simple Example: An Ankle Sprain.
Imagine a rugby player rolls his ankle during training. The ankle becomes painful and swollen
The old approach might have been:
Rest completely until the pain disappears and eventually begin exercising again.
A modern rehabilitation approach may look more like:
Initially protect the ankle and control the symptoms. Once appropriate, begin comfortable ankle movement and gradually restore weight-bearing.
Begin basic strength and balance exercises and progress to single-leg control. Introduce running and progress to acceleration, jumping and change of direction.
Complete sport-specific rehabilitation before return to competition. Current clinical guideline for lateral ankle sprain recommend progressive weight-bearing with appropriate support and structured therapeutic exercise.
More severe ankle sprains may still require a short period of immobilisation sometimes up to approximately 10 days.
This highlights the key point: The correct starting point depends on the injury.
Pain Is Information, Not the Only Progression Rule.
Rehabilitation shouldn’t simple be:
“If it hurts, stop everything.”
But it also shouldn’t be:
“No pain, no gain.”
Pain, swelling, range of motion, strength, function and the response to the previous exercise session all provide information about how the injury is tolerating load. The rehabilitation programme can then be adjusted accordingly.
Why Work With a Biokineticist?
Once you reach the exercise-rehabilitation stage, rehabilitation should become progressively more individualised.
A Biokineticist can help assess:
Strength.
Range of motion.
Movement quality.
Balance and control.
Strength differences between limbs.
Functional capacity.
Sport-specific demand.
Objective testing can then be used to determine whether the patient is ready for the next stage rather than progressing purely according to time.
At Horn Rehab & Performance, our goal is not simply to get someone pain-free. Our goal is to progressively rebuild the capacity needed for work, daily activity or sport.
