What Physiotherapists Look at During a Running Injury Assessment

Running is one of the most popular forms of exercise because it is simple, accessible, and incredibly effective for improving cardiovascular health. However, the repetitive nature of running means the body experiences thousands of loading cycles during a single run, which can lead to overuse injuries when movement patterns, strength, or training load are not optimal. Small asymmetries in mobility, strength and endurance become very apparent with these thousands of steps.

When a runner visits a physiotherapist with pain or an injury, the goal is not only to treat the symptoms but to identify why the injury occurred and how to prevent it from returning. A comprehensive running injury assessment evaluates multiple factors that influence how the body moves and absorbs forces while running. Physiotherapists commonly assess gait mechanics, cadence, mobility, and muscle strength to identify potential contributors to injury.

Below are the key components of a thorough running assessment.

Gait Analysis

One of the most important parts of a running assessment is gait analysis. This involves observing and analyzing how a runner moves while running. During gait analysis, a physiotherapist may look at:

• Foot strike pattern

• Stride length and width

• Pelvic control

• Knee alignment

• Trunk posture

• Arm swing and overall running rhythm

Research has shown that running injuries are often associated with biomechanical factors such as excessive loading, altered joint angles, or inefficient movement patterns. Identifying these factors helps guide treatment and running retraining strategies.

Cadence Analysis

Cadence refers to the number of steps a runner takes per minute. It is an important biomechanical variable because it influences the amount of force that travels through the body with each step.

Evidence suggests that slightly increasing cadence (often by about 5–10%) can reduce stress on the hips, knees, and tibia by shortening stride length and reducing ground reaction forces. Studies have also found that increasing cadence may decrease peak impact forces and vertical loading rates during running, which are factors associated with common overuse injuries such as patellofemoral pain and tibial stress fractures.

During a running assessment, a physiotherapist may measure cadence and evaluate whether changes to step rate could help reduce stress on injured tissues.

Mobility Screening

Mobility limitations in the hips, ankles, or spine can significantly affect running mechanics.

A physiotherapist will typically assess:

• Hip mobility (especially extension and rotation)

• Ankle dorsiflexion

• Thoracic spine mobility

• Hamstring and calf flexibility

When joints cannot move through their full range of motion, the body often compensates elsewhere. For example:

• Limited ankle mobility may increase stress on the knee

• Poor hip mobility can alter stride mechanics

• Reduced spinal mobility may affect posture and force distribution

  
  

Mobility screening helps determine whether stiffness or restrictions are contributing to inefficient running mechanics or increased injury risk.

Strength Testing

Muscle strength plays a critical role in absorbing the forces generated during running. Weakness in certain muscle groups can lead to poor control of the lower limbs and pelvis. Physiotherapists commonly assess strength in:

• Gluteal muscles (hip stabilizers)

• Quadriceps and hamstrings

• Calf muscles

• Core and trunk stabilizers

Research has consistently linked weakness in the hip and trunk muscles with several common running injuries, including patellofemoral pain and iliotibial band syndrome.

Strength testing allows physiotherapists to identify deficits that may cause the body to compensate during running, leading to excessive stress on certain tissues.

Why a Comprehensive Assessment Matters

Running injuries are rarely caused by just one factor. Instead, they usually result from a combination of training load, biomechanics, mobility, and strength. A thorough physiotherapy assessment helps identify:

• Movement patterns contributing to injury

• Muscular imbalances

• Mobility restrictions

• Inefficient running mechanics

• Opportunities for gait retraining

  
  

Once these factors are identified, a physiotherapist can create an individualized treatment plan that may include:

• Strength and conditioning exercises

• Mobility work

• Running technique adjustments

• Cadence retraining

• Gradual return-to-running programs

  
  

The goal is not only to help runners recover but to help them run stronger, more efficiently, and with a lower risk of future injury.
