Biomechanics

What is Biomechanics?

Biomechanics is the study of the mechanical laws relating to the movement or structure of living organisms. It combines mechanics and biology principles to understand how the body moves and functions. This field examines the forces exerted by muscles and gravity on the skeletal structure and how these forces impact movement and physical performance. 


Biomechanics is essential in physical therapy, sports science, orthopaedics, and ergonomics to enhance movement efficiency, reduce injury risk, and improve overall physical function.


Who Can Benefit from Biomechanics?

Biomechanics can benefit a wide range of individuals, including:

  • Athletes - To enhance performance, optimise training, and prevent injuries.
  • Patients with Musculoskeletal Issues—Biomechanical assessments and treatments can benefit patients suffering from arthritis, back pain, or joint disorders.
  • Post-operative Patients - Individuals recovering from joint replacements or ligament repairs.
  • Children with Developmental Disorders - To address and correct movement-related issues early in life.
  • Elderly Individuals - To maintain mobility, improve balance, and reduce the risk of falls.
  • Professionals - Workers in physically demanding jobs can use biomechanics to prevent workplace injuries and improve ergonomic practices.


Benefits of Biomechanics

Biomechanics offers numerous benefits, including:

  • Injury Prevention - By understanding movement patterns and forces, biomechanics can help prevent injuries.
  • Performance Enhancement - Athletes and individuals can improve their physical performance through biomechanical analysis and training.
  • Rehabilitation - Effective recovery from injuries or surgeries through targeted exercises and treatments.
  • Customised Treatments - Personalized approaches to treatment based on an individual's specific movement patterns and needs.
  • Improved Ergonomics - Enhancing workplace designs and practices to reduce the risk of injury and improve comfort.
  • Better Understanding of Movement Disorders - Insights into the causes and potential treatments for various movement-related issues.


Types of Biomechanics

Biomechanics is divided into several types, each focusing on different aspects of movement and function:

  • Static Biomechanics - Studies systems that are in a constant state of motion or at rest, examining forces without movement.
  • Dynamic Biomechanics - Focuses on bodies in motion and the forces causing this motion.
  • Kinematics - Describes the motion of bodies without considering the forces causing the motion.
  • Kinetics - Examines the forces that cause or result from motion.
  • Clinical Biomechanics - Applies biomechanical principles to diagnose, treat, and prevent medical conditions.
  • Occupational Biomechanics - Studies the interactions between workers and their tasks, tools, and work environments to improve safety and efficiency.
  • Sports Biomechanics - Analyses athletic performance and techniques to enhance performance and reduce injury risk.


Alternative Options to Biomechanics

While biomechanics offers valuable insights and solutions, there are alternative approaches to understanding and improving movement and physical function:

  • Physical Therapy - Focuses on rehabilitation and treatment of movement disorders through exercises, manual therapy, and other modalities.
  • Chiropractic Care - Emphasises diagnosing and treating mechanical disorders of the musculoskeletal system, particularly the spine.
  • Occupational Therapy - Helps individuals perform daily activities through therapeutic techniques and adaptive equipment.
  • Sports Medicine - Combines medical knowledge with sports science to treat and prevent injuries related to sports and exercise.
  • Ergonomics - Studies how to design workspaces, tools, and tasks to fit the user's needs, reducing strain and injury risk.
  • Exercise Physiology - Examines the body's responses to physical activity and develops exercise programs to improve health and performance.


What to Do Before a Biomechanics Assessment?

Before undergoing a biomechanics assessment, there are several steps you can take to ensure that you are adequately prepared:

  • Consult with a Specialist: Speak with a healthcare professional or a biomechanics specialist to understand the purpose of the assessment and how it can benefit you.
  • Medical History: Provide a detailed medical history, including any injuries, surgeries, or chronic conditions. This information will help the specialist tailor the assessment to your specific needs.
  • Wear Appropriate Clothing: Dress in comfortable, form-fitting clothes that allow for easy movement. Avoid loose or restrictive clothing that could interfere with the assessment.
  • Prepare Questions: Write down any questions or concerns about the assessment. This will help ensure that you get all the information you need.
  • Hydrate and Eat Lightly: Make sure you are well-hydrated and have eaten a light meal or snack to maintain energy levels during the assessment.
  • Warm Up: Perform a light warm-up before the assessment to loosen your muscles and prepare your body for movement.


What Happens During a Biomechanics Assessment?

A biomechanics assessment typically involves several stages:

  • Initial Consultation: The specialist will discuss your medical history, current issues, and goals for the assessment. This helps to tailor the evaluation to your specific needs.
  • Physical Examination: The specialist will conduct a physical examination to assess your posture, alignment, and any visible abnormalities.
  • Motion Analysis: This may involve video recording or using motion capture technology to analyse your movements in detail. You may be asked to perform specific tasks like walking, running, or performing sports-specific movements.
  • Force and Pressure Measurements: Sensors or force plates may measure the forces exerted by your muscles and joints during movement.
  • Muscle Activity Analysis: Electromyography (EMG) sensors may measure muscle activity and identify imbalances or weaknesses.
  • Data Analysis: The collected data is analysed to identify patterns, abnormalities, and areas for improvement.
  • Feedback Session: The specialist will discuss the findings with you, explaining any issues and suggesting possible interventions or treatments.


What to Expect After a Biomechanics Assessment?

  • Detailed Report: You will receive a detailed report outlining the assessment's findings, including any identified issues and recommendations for improvement.
  • Personalised Plan: A personalised plan will be developed based on the assessment results. This plan may include exercises, stretches, lifestyle changes, or other interventions to address your needs.
  • Follow-Up Appointments: Regular follow-up appointments may be scheduled to monitor your progress and adjust your plan as needed.
  • Increased Awareness: You will better understand your body mechanics, which can help you make more informed decisions about your physical activities and overall health.
  • Improved Performance and Comfort: Implementing the recommended plan can improve your physical performance, reduce discomfort, and lower your risk of injury.


Biomechanics Prognosis

Generally, the prognosis is favourable for those who follow their personalised plan closely. Benefits include:

  • Improved Movement Efficiency
  • Reduced Pain and Discomfort
  • Lower Injury Risk
  • Enhanced Athletic Performance
  • Better Overall Health


Biomechanics Risks

While biomechanics assessments and interventions are generally safe, there are potential risks to consider:

  • Incorrect Analysis: If the assessment is not conducted correctly, it may lead to incorrect conclusions and ineffective or harmful interventions.
  • Overexertion: Some individuals may overexert themselves during exercises or activities recommended, leading to muscle strain or injury.
  • Discomfort: Some assessments, especially those involving physical manipulation or intensive exercises, may cause temporary discomfort.
  • Delayed Results: Benefits from biomechanical interventions may take time to manifest, which can be frustrating for some individuals.


What if Biomechanics is Delayed?

Delaying a biomechanics assessment can have several implications:

  • Prolonged Discomfort: Individuals may continue to experience pain or discomfort that could have been addressed earlier.
  • Increased Injury Risk: Without proper assessment and intervention, the risk of injury may increase, particularly for athletes or individuals engaging in physical activities.
