Gait Analysis for Runners — What It Is, When You Need It, and What to Expect

Running gait analysis is one of the most informative tools in sports physiotherapy — and one of the most misunderstood. Many runners associate "gait analysis" with the shoe shop test on a treadmill for 30 seconds. Clinical gait analysis is significantly more comprehensive and far more useful. This guide explains what a proper running gait analysis involves, what it can identify, and when you should consider one.

What is Running Gait Analysis?

Running gait analysis is a detailed assessment of how you run — examining the biomechanics of your stride to identify patterns that may contribute to injury, reduce efficiency, or limit performance. At Lambert Sports Clinic, we use AI-assisted gait analysis software that uses computer vision and machine learning to quantify key parameters in real time and over multiple strides.

A clinical gait analysis assesses:

• Foot strike pattern: forefoot, midfoot, or heel striker; degree of supination or overpronation
• Cadence: steps per minute — optimal is typically 170–180 spm for most recreational runners
• Stride length and symmetry: whether left and right sides are equal
• Vertical oscillation: how much you bounce up and down — excessive bounce wastes energy
• Hip drop (Trendelenburg sign): the pelvis dropping on the swing side, indicating weak hip abductors
• Knee alignment: valgus collapse (knees falling inward) during stance phase
• Arm swing: rotation, crossing the midline, symmetry
• Forward lean: body position relative to the foot strike

What Problems Does Gait Analysis Identify?

The most clinically significant gait patterns associated with running injuries include:

Hip Drop (Contralateral Pelvic Drop)

When the hip drops on the swing side during single-leg stance, it increases load on the IT band, lateral hip structures, and the medial knee. It reflects weakness in the gluteus medius — the hip abductor that stabilises the pelvis during running. This is associated with: IT band syndrome, patellofemoral pain (runner's knee), hip bursitis, and stress fractures of the femur or tibia.

Knee Valgus Collapse

The knee caving inward during the stance phase increases patellofemoral load and medial knee stress. Associated with: patellofemoral pain, ACL injuries, and IT band syndrome. Often combined with hip drop and foot overpronation.

Overstriding

Landing with the foot well ahead of the body's centre of mass creates a braking force with every stride, increasing tibial stress and anterior knee load. Increasing cadence by 5–10% typically reduces overstriding and decreases impact forces by 15–25%.

Excessive Pronation

Some pronation is normal and functional — the foot needs to absorb impact. Excessive or prolonged pronation throughout the stance phase can overload the plantar fascia, Achilles tendon, and tibialis posterior, contributing to plantar fasciitis, Achilles tendinopathy, and medial tibial stress syndrome.

Heel Striking at Distance

Heavy heel striking at recreational pace is associated with higher impact transient forces. Transitioning toward a midfoot strike can reduce impact, but should be done gradually — forced forefoot running without muscular preparation dramatically overloads the calf and Achilles.

AI Gait Analysis at Lambert Sports Clinic

At Lambert Sports Clinic we use AI-assisted gait analysis software that quantifies joint angles, pelvic metrics, cadence, and symmetry automatically — producing objective measurements that can be compared before and after a rehabilitation programme. This level of precision allows us to:

• Measure hip drop angle in degrees (not just observe it qualitatively)
• Track changes in gait parameters over a rehabilitation course
• Identify asymmetries that may not be visible to the naked eye
• Provide runners with clear, evidence-based feedback on their gait

The gait analysis is conducted by our HCPC-registered physiotherapists alongside a clinical assessment — not in isolation. The gait findings are interpreted in context with your injury history, strength assessment, and training load to form a clinically meaningful picture.

When Should a Runner Get a Gait Analysis?

• Recurrent injuries: If you keep getting the same injury (or different injuries on the same side), a gait pattern is likely contributing
• Returning from a significant injury: To ensure compensatory patterns have resolved before resuming training
• Starting a marathon or structured training programme: Identifying risk factors before high-volume training is much more effective than treating injuries after they occur
• Performance plateau: Improving running economy reduces energy expenditure at any given pace
• Post-surgical return to running: To ensure altered mechanics from surgery or time off are addressed

What Happens After Gait Analysis?

Gait analysis findings drive a targeted physiotherapy programme. If hip drop is identified, the programme focuses on gluteus medius strengthening. If overstriding is found, cadence work and footwear advice is given. If knee valgus is a factor, hip and knee strengthening is prescribed. The intervention addresses the cause — not just the symptom.

At Lambert Sports Clinic, most patients who have gait analysis also complete a rehabilitation programme supervised by one of our physiotherapists, with follow-up gait analysis at 6–8 weeks to quantify the improvement.
