Why your gait changes with age — and what to do

Three things shift gait with age: balance, joint stiffness, and muscle weakness. Stride length shortens, walking speed drops, posture changes. All of it is preventable and reversible to a significant degree. A professional gait assessment shows you exactly where your walking is breaking down and what to train.

Gait is the integration

Walking looks simple. It’s not. Every step is a controlled fall — momentum carries you forward, one leg catches you, the other swings through, your trunk rotates, your arms counter-swing, your eyes scan ahead, your inner ear stabilises. Hundreds of micro-decisions per minute, all happening below conscious awareness.

When that integration starts to degrade — even slightly — the whole system compensates. Stride shortens to give you more time. Speed drops because the system is less confident. Posture shifts to keep you over your centre of gravity. None of it feels like a problem until one day, it does.

The three things that shift

First, balance. As the vestibular and proprioceptive systems become less precise, you walk more carefully — less heel-strike, shorter stride, less push-off through the toes.

Second, joint stiffness. Hips, ankles, and the thoracic spine lose range. You walk with less hip extension, less ankle dorsiflexion, less trunk rotation. The whole gait becomes more ‘mechanical.’

Third, muscle weakness — particularly in the glutes, calves, and core. Without sufficient push-off and stability, you take smaller, more cautious steps.

Walking speed is one of the most reliable predictors of healthy ageing. It’s also one of the most trainable.

What a gait assessment shows

At Team8, our physiotherapists watch you walk on video, slow it down, and identify exactly where the system is compensating. Maybe your right hip isn’t extending. Maybe your left calf isn’t pushing off. Maybe your trunk is rotating less than it should. Each finding maps to a specific training intervention.

This is the gap between general ‘walk more’ advice and an actual rehab program. The first treats the symptom. The second fixes the cause.

What you can train

The good news is that gait responds quickly to targeted work. Mobility for the stiff joints, strength for the weak muscles, balance for the cautious nervous system. Within 6-12 weeks, most people see measurable changes in stride length and walking speed — and they feel it: walking feels easier, longer walks become possible again, stairs feel less like a task.

Move from understanding to action

Theory only takes you so far.

Knowing about strength, balance, or pain is one thing. Having a clinician build you a personalised program is another. Come and see what supervised, evidence-based training looks like in practice.
