Biomechanical Analysis: Unearthing the Root Causes of Foot and Lower Extremity Pain

Chelmsford Physio • February 11, 2025

Experiencing pain in your feet or lower extremities can be not just discomforting but also a hindrance to your daily activities. While there are various reasons for such pains, a biomechanical analysis often holds the key to understanding and effectively addressing these issues. In this article, we delve into how biomechanical analysis can help in identifying the root causes of foot and lower extremity pain.


Understanding Biomechanics

Biomechanics refers to the study of the mechanical laws relating to the movement or structure of living organisms. In the context of physiotherapy, it involves analysing how the bones, muscles, tendons, and ligaments work together to move. Any imbalance or irregularity in this delicate system can lead to pain and discomfort.


The Role of Feet in Biomechanics

Feet, being the foundation of our body, plays a pivotal role in our biomechanics. They bear the weight of our entire body and are essential for movement. Problems in the feet often lead to a domino effect, causing issues in the knees, hips, and even the lower back.


Common Causes of Pain

Improper Footwear

Wearing shoes that do not support or align with the natural structure of your feet can lead to pain. This is often seen in individuals who wear high heels or ill-fitting shoes for prolonged periods.


Overuse and Sports Injuries

Athletes or individuals engaging in regular physical activities might experience pain due to overuse of certain muscles or from sports-related injuries.


Age-Related Changes

As we age, changes in the structure of our feet, such as the flattening of arches, can cause pain and discomfort.


Medical Conditions

Certain medical conditions like arthritis, diabetes, and obesity also contribute to foot and lower extremity pain.



Gait Analysis

This involves observing how an individual walks or runs. It helps in identifying issues like overpronation (rolling inwards of the foot) or supination (rolling outwards of the foot), which are common causes of pain.


Pressure Mapping

Pressure mapping technologies can be used to understand how weight is distributed across the feet. This is crucial in identifying areas that are under excessive stress.



Treatment and Management

Based on the findings from the biomechanical analysis, a tailored treatment plan can be developed. This may include:


Orthotic Therapy: Custom-made insoles can be used to correct foot imbalances.

Exercise Regimens: Specific exercises to strengthen the muscles and improve flexibility.

Footwear Advice: Guidance on selecting the right footwear to support your feet.

Manual Therapy: Techniques such as massage and mobilisation to alleviate pain and improve function.


Understanding the biomechanical causes of foot and lower extremity pain is crucial in developing effective treatment plans. By analysing how the body moves and identifying any imbalances, it’s possible to address the root cause of the pain, rather than just treating the symptoms.

My journey to become a qualified Physiotherapist began with a desire to build on my existing experience in sport and private practice. Over the past two years, I’ve had the opportunity to complete a variety of placements, including stroke, respiratory, community rehabilitation and two musculoskeletal placements - one of which specialised in post-operative care. Each placement challenged me in different ways and enabled me to develop a deeper appreciation for patient-centred care across a range of settings. Throughout this time, I’ve been able to build on the skills I gained as a Sports Therapist while learning new approaches that have shaped a more holistic view of health and rehabilitation. Combining the strengths of both degrees has really helped me grow as a professional. The past two years have taught me invaluable clinical, professional, and personal lessons, and I truly believe they have played a key role in shaping me into a well rounded Physiotherapist.
