How Walking Affects the Body: A Physio’s Perspective
Walking is something most of us do without thinking about it.
But the way we walk is actually a complex movement involving the feet, ankles, knees, hips, pelvis, trunk and even the movement of our arms.
Everyone's walking pattern is slightly different. Some people take longer strides, some walk quickly, some naturally turn their feet out, and others move with relatively little rotation through the trunk.
There is no single “perfect” way to walk.
However, the way we move can influence how force is distributed through the body. When pain, injury or weakness is present, changes in gait can sometimes become part of the problem, or simply provide useful clues about what is happening elsewhere.
Walking Is a Whole-Body Movement
Although we often think of walking as a leg activity, almost the entire body contributes.
During each step, the body has to:
- Accept your body weight as the foot contacts the ground.
- Control movement through the foot and ankle.
- Manage load through the knee.
- Stabilise the pelvis while standing on one leg.
- Generate force through the hip and calf to move the body forwards.
- Control movement through the trunk.
- Coordinate arm swing with the movement of the legs.
These movements happen repeatedly, often thousands of times each day.
That repetition is one reason gait can be useful to assess when someone has ongoing pain or difficulty walking comfortably.
How Does Walking Affect Joint Load?
Every time your foot contacts the ground, forces travel through the body.
This is normal. Our bones, muscles, tendons and joints are designed to tolerate load.
The body also has multiple ways of absorbing and redistributing these forces. Movement through the ankle, knee and hip, along with muscle activity throughout the lower limb and trunk, all contribute.
Problems do not necessarily occur because someone has an unusual-looking walking pattern. More often, the issue is that a particular tissue may currently have less capacity than the load being placed on it.
In those situations, understanding how someone walks can help us work out where those forces are going and whether there is anything useful to modify.
Why Does Gait Change When We Are in Pain?
The body is very good at adapting.
If your knee hurts, you may shorten your stride. If your ankle is stiff, you may turn the foot out slightly. If one hip feels weak or uncomfortable, you might spend less time standing on that leg.
These changes are often completely logical responses to pain.
In the short term, changing the way you walk can help protect a sore area and allow you to keep moving.
However, sometimes a compensatory pattern continues after the original problem has started to settle. Other times, the compensation shifts load somewhere else and becomes relevant to a person's ongoing symptoms.
This is where gait analysis can be useful.
What Do Physiotherapists Look at During Gait Analysis?
Gait analysis is not about deciding whether someone walks “correctly” or “incorrectly”.
Instead, we are looking for movement patterns that might help explain the person's symptoms or limitations.
Depending on the problem, we may consider:
- Step length: Whether one side takes a shorter or longer step.
- Walking speed: Whether pain or weakness is slowing the gait pattern.
- Foot position: How the foot lands and moves through stance.
- Ankle movement: Whether there is enough movement through the ankle as the body passes over the foot.
- Knee control: How the knee moves during weight-bearing.
- Hip and pelvic control: How the pelvis behaves while standing on one leg.
- Trunk movement: Whether the body is leaning or rotating to compensate for another area.
- Arm swing: How the upper body coordinates with the lower body.
- Symmetry: Whether one side is behaving significantly differently from the other.
The key question is not simply, “Does this gait look different?”
It is, “Does this movement pattern matter for this particular person and their problem?”
What Can a Walking Assessment Tell Us?
A walking assessment can sometimes reveal things that are less obvious when someone is lying on a treatment table.
For example, a person may have reasonable hip strength during a simple test but struggle to control their pelvis once they are repeatedly loading one leg during walking.
Someone recovering from an ankle injury may have regained strength but still avoid moving fully over the ankle during each step.
A person with knee pain may be unknowingly taking a much shorter step on one side.
These findings do not automatically identify the cause of pain, but they can provide another piece of the puzzle.
Gait Analysis Is Only One Part of the Assessment
Watching someone walk in isolation rarely gives us the whole answer.
At RHP Physiotherapy, gait analysis is usually combined with a broader assessment of:
- Joint mobility.
- Muscle strength.
- Balance and coordination.
- Single-leg control.
- Pain behaviour.
- Previous injuries.
- Training or activity levels.
- Footwear where relevant.
- The physical demands of work, exercise or sport.
This allows us to take a more holistic view.
For example, changing someone's walking technique may achieve very little if the real issue is that their calf currently lacks the strength to tolerate the amount of walking they are doing.
Likewise, strengthening alone may not fully solve the problem if someone continues to avoid loading one side because of pain or habit.
The assessment helps determine which factors actually matter.
Can Walking Technique Cause Pain?
Sometimes gait can contribute to symptoms, but it is rarely as simple as one movement pattern being “bad”.
People can have very different walking styles and remain completely pain-free.
Pain is usually influenced by a combination of factors including:
- The amount of activity being performed.
- The capacity of the muscles and tendons.
- Previous injury.
- Joint mobility.
- Strength.
- Recovery and fatigue.
- How quickly activity has increased.
- The way load is distributed during movement.
For this reason, gait modification is most useful when there is a clear reason for making a change rather than simply trying to make someone's walking pattern look more “normal”.
What Types of Problems Can Gait Analysis Help With?
Walking analysis can be useful across a broad range of presentations.
These may include:
- Knee pain.
- Hip pain.
- Foot and ankle pain.
- Achilles tendon problems.
- Plantar heel pain.
- Lower back pain.
- Recovery after lower-limb surgery.
- Rehabilitation after a fracture.
- Persistent limping after injury.
- Difficulty returning to normal walking after time in a boot or on crutches.
- Balance and mobility problems.
For runners, the same principles can be extended into a more detailed assessment of running mechanics and the much higher loads associated with running.

Can You Change the Way You Walk?
Yes, but we do not necessarily need to.
Walking is a highly practiced movement pattern. Over years, your nervous system becomes very efficient at reproducing your usual gait without requiring much conscious thought.
When there is a reason to change a particular feature of walking, this usually needs to be practised rather than simply explained once.
That may involve:
- Walking drills.
- Strength exercises.
- Balance exercises.
- Improving ankle or hip mobility.
- Practising step length or walking speed.
- Gradually increasing confidence loading an injured leg.
- Using external cues to help change a particular movement.
As the movement becomes more familiar, it can gradually require less conscious effort.
What About Posture While Walking?
There is no single ideal posture that everybody should maintain when walking.
Some people naturally walk more upright. Others use slightly more trunk movement or rotation. These differences are not automatically a problem.
Instead of trying to force everyone into the same position, we are more interested in whether a person's posture or movement is:
- A response to pain.
- Limiting comfortable movement.
- Increasing the demand on another area.
- Preventing them from walking at the speed or distance they want.
Movement variability is normal. The aim is usually to make walking comfortable and efficient enough for the demands of your life, not to create a textbook-perfect walking pattern.
Walking Is Also an Important Part of Rehabilitation
Walking is not just something we assess. It can also be an important rehabilitation tool.
After injury or surgery, gradually increasing walking can help rebuild:
- General physical capacity.
- Lower-limb strength and endurance.
- Confidence loading the affected side.
- Cardiovascular fitness.
- Tolerance to everyday activity.
For some people, the progression might begin with short periods around the house. For others it may involve gradually building towards longer walks, hills, faster walking or eventually returning to running.
The appropriate amount depends on the person, the injury and what they are trying to achieve.
So, How Do You Walk?
The way you walk is individual to you.
Most differences in gait are simply normal variations and do not need to be corrected.
But when pain, injury, weakness or reduced mobility is present, walking can provide valuable information about how the body is currently managing load.
At RHP Physiotherapy, we use gait analysis as one part of a broader physiotherapy assessment. By combining movement analysis with strength, mobility, function and your individual goals, we can determine whether changing the way you move is actually useful.
The aim is not to teach everybody to walk the same way.
It is to help you move comfortably, confidently and with enough physical capacity to do what you want to do.
