Foundation Blocks in Sports Medicine[edit | edit source]

Disablement Models[edit | edit source]

Disablement models are conceptual models which provide a framework for clinical practice and research.[1] These models are tools that are used to define impairment and more recently functioning and are utilised by governments and society to device strategies and policies for meeting the needs of people who have a loss in function as a result of health conditions, disease or injury. These models are used in healthcare as a way to organise clinical practice decisions. It creates a common language among healthcare professionals and facilitates patient-centred and whole-person healthcare.[1] Disablement models are an important piece of evidence-based practice. Evidence-based practice entails clinician expertise, research evidence and patient preferences and values. It is key to incorporate research evidence and the values of patients into their care model. A disablement model facilitates this incorporation.[1]

  • Disablement model
    The disablement model starting point may be pathology or pathophysiology (such as an injury)
  • This may lead to an impairment (such as pain or loss of range of motion) and because of that there is a functional limitation (i.e. the inability to do some activity or having difficulty performing the activity).
  • This leads to the determination of disability (i.e. the individual's perception of how specific functional limitations affect their activities of daily living (ADL), instrumental activities of daily living (IADL), work ability, participation in recreational activities or sport).
  • Other components that play a role are:
    • Biological factors
    • Congenital factors
    • Genetic predisposition
    • Demographic factors such as age, sex, education, income
    • Comorbidities
    • Health habits
    • Personal behaviours
    • Lifestyle
    • Psychological attributes (motivation, coping)
    • Social support
    • Physical and social environment
    • Medical care, medication therapies, rehabilitation and mode of onset and duration of injury

From a sports perspective, prevention and promotion of health, wellness and fitness help mediate the development of pathology or the outcome.[2]

The International Classification of Functioning, Disability and Health (ICF) is a disablement model used worldwide. Read more about it here: Introduction to the International Classification of Functioning, Disability and Health (ICF)

Anatomy and Biomechanics[edit | edit source]

A good understanding of anatomy and biomechanics is critical in sports medicine. It adds value and understanding to mechanisms of injury, prevention of injury and also the treatment of the specific structure and any collateral damage elsewhere in the kinetic chain. A relevant definition of biomechanics for sports medicine clinicians is[3]:

"The application of mechanical principles in the study of living organisms."[3]

Exercise Physiology[edit | edit source]

An understanding of the basic principles of the body's response to an exercise stimulus is vital for the performance and rehabilitation of athletes. This knowledge guides sports clinicians in terms of exercise prescription, rehabilitation and prevention of injury.

Continuum of Mechanical Stress[edit | edit source]

The different tissues in the body will respond differently under different levels of stress. Biological tissues show characteristic responses to physical stress and each response will occur within a defined range along the continuum of mechanical stress. The responses include:

Summary of Mechanical Stress Continuum[4]
Response to Mechanical Stress Explanation of Response
Atrophy Physical or mechanical stress levels lower than the maintenance range leads to a decreased tolerance in tissue to subsequent stresses
Maintenance Physical or mechanical stress levels in the maintenance range result in no apparent tissue change
Hypertrophy Physical or mechanical stress levels that exceed the maintenance range (overload) lead to an increased tolerance in tissue to subsequent stresses
Overuse High levels of physical stress may lead to the overuse of tissue structures
Acute Injury Excessively high levels of physical stress may lead to tissue injury
Mechanical Stress Continuum

SAID Principle[edit | edit source]

SAID = Specific Adaptations to Imposed Demand

  • The SAID principle is a framework on which strength and conditioning programmes can be designed[5]
  • Biological tissue adapts to the demands, or the lack of demand, imposed on it
  • Components of the SAID principle include[5]:
    • Overload - tissue is challenged with increased intensity and/or duration
    • Specificity - the tissue will adapt to the activity trained

General Physical Rehabilitation Pyramid[edit | edit source]

The general physical rehabilitation pyramid includes five tiers. The bottom tier can be considered the first and most important. Individuals should be evaluated for the components of each tier and the clinician needs to be satisfied that progression to the next tier will not hinder the healing and rehabilitation process.[7]

General Physical Rehabilitation Pyramid
  • General physical rehabilitation pyramid tiers (Tier 1 (bottom tier) to Tier 5 (top tier))
    1. Static proprioception and cognitive facilitation; correction of faulty mechanics and tissue lengthening
    2. Cardiovascular conditioning and dynamic proprioception training
    3. Progressing stabiliser conditioning
    4. Mobiliser conditioning
    5. ADL conditioning (or in sports medicine: sport-specific conditioning)

Sports Rehabilitation Pyramid[edit | edit source]

Return to sport or physical activity is the goal and important to athletes recovering from injury. This return to sport goal is supported by multiple components such as:

  • Sports Rehabilitation Pyramid
    Cardiovascular endurance
  • Nutrition
  • Psychological well-being
  • Athlete education
  • Building blocks of rehabilitation considerations such as:
    • Pre-injury health status
    • Tissue healing constraints
    • Muscle flexibility and joint stability
    • Muscle strength, power and endurance
    • Balance and proprioception
    • Motor control and skill acquisition
    • Functional activity progression

All of the components and considerations mentioned above are supported by a sports medicine team consisting of professionals who have the relevant knowledge, skills and abilities.

Underpinning all of the above are:

  • Skills to diagnose accurately
  • Acute care management skills
  • Relevance and influence of surgical intervention
  • Excellent rehabilitative skills and competencies

Responsibilities of the Sports Physiotherapist[edit | edit source]

Prevention[edit | edit source]

  • Facilitate safe conditioning
    • Ensure proper instruction on how to perform the exercise
    • Check that equipment is safe to use
  • Sanitation
    • Continuing physical activity or exercise may prolong or aggravate infectious diseases[12]
    • Infection control measures should be followed. These include hand washing, cleaning of facilities, preventing shared use of personal items (i.e. water bottles)[12]
    • Early diagnosis can reduce transmission risk, reduce time loss from play and prevent larger breakouts[12]
  • Promotion of nutritional concerns

Recognition, Evaluation and Assessment[edit | edit source]

  • History
  • Observation
    • Sports medicine professionals "need to spend time pitchside."[14] "Sport-specific knowledge and team internal group dynamics are integral part of excellent communication and collaboration that are essential for us to serve athletes very well."[14]
  • Palpation
  • Special tests
  • Assessment
  • Educate
  • Inform
  • Plan
