Musculoskeletal Medicine and Disorders
Musculoskeletal medicine concerns the diagnosis, classification, and conservative management of disorders affecting the bones, joints, muscles, tendons, ligaments, and related connective tissues. Within physical medicine and rehabilitation it is the area that frames how degenerative, inflammatory, and injury-related conditions of the locomotor system are understood and rehabilitated.
Definition
Musculoskeletal disorders are conditions that impair the structure or function of the locomotor system — bones, joints, cartilage, muscles, tendons, ligaments, and bursae — and that commonly present with pain, stiffness, weakness, or limited movement.
Scope
This area orients the reader to the major categories of musculoskeletal disorder represented in its topics: degenerative joint disease (osteoarthritis), systemic inflammatory arthritis (rheumatoid arthritis), overuse disorders of tendon (tendinopathy), regional soft-tissue pain (myofascial pain syndrome), and acute soft-tissue injury (ligament and muscle strain). It presents these as reference concepts for education and evidence appraisal rather than as a treatment manual.
Sub-topics
Key concepts
- Degenerative versus inflammatory joint disease
- Mechanical loading and tissue overload
- Pain, stiffness, and functional limitation
- Conservative and rehabilitative management
- Acute injury versus chronic overuse
- Disability and quality-of-life burden
Mechanisms
Musculoskeletal disorders arise through several broad pathways that recur across the topics in this area: degeneration of cartilage and joint tissues under mechanical and metabolic stress, immune-mediated synovial inflammation, maladaptive responses of tendon and muscle to repetitive or excessive load, and acute mechanical disruption of soft tissue. Recognising which pathway dominates a given presentation is central to how these conditions are classified and rehabilitated.
Clinical relevance
Musculoskeletal disorders are among the leading global contributors to years lived with disability, and they are a core part of rehabilitation practice. International guideline syntheses emphasise patient-centred assessment, education, and active management as consistent themes across these conditions. This area describes the conceptual landscape and is not a substitute for individualised clinical assessment or treatment.
Epidemiology
Musculoskeletal conditions collectively affect a large fraction of the population and rank among the top causes of disability worldwide; osteoarthritis in particular accounts for a substantial and rising share of that burden as populations age.
History
The conservative and rehabilitative care of musculoskeletal disorders developed alongside physical medicine and rheumatology through the twentieth century, integrating insights from orthopaedics, sports medicine, and pain science as imaging and biomechanics matured.

Frequently asked questions
- What does 'musculoskeletal' cover?
- It refers to the locomotor system: bones, joints and cartilage, skeletal muscle, and the connective-tissue structures (tendons, ligaments, bursae) that link and stabilise them.
- Why are musculoskeletal disorders important in rehabilitation?
- They are a leading cause of pain and disability worldwide, and much of their management is conservative and rehabilitative — making them a central focus of physical medicine and rehabilitation.
