Introduction[edit | edit source]

Adverse ergonomic factors is considered risky. Especially, bad postures, high loads, fast movements, reduced recovery time is proved to be harmful to the upper extremity.

Work-related musculoskeletal disorders (WRMDs) refer to the musculoskeletal disorders that are caused by one's work

  1. Common in occupations such as manufacturing, industrial technicians, office workers, etc.
    • Tasks that require precise motor control and extended working hours in same posture[1]
    • Repetitive movements
    • Static contractions[2]
  2. Primary cause of work-related disability and loss of productivity[3]
  3. High workload and sustained stress may result in anxiety and mental health issue[1]

Clinically Relevant Anatomy[edit | edit source]

As we targeting the musculoskeletal disorders at neck and upper limb, these anatomy structure may be included in WRMDs:

  • Neck
  • Cervical and thoracic spine
  • Shoulder joint
  • Elbow
  • Forearm
  • Wrist
  • Fingers

Clinical Presentation[edit | edit source]

Carpal Tunnel Syndrome.png
  • Musculoskeletal pain and myalgias[1]
  • Muscle stiffness
  • Redness
  • Weakness[4]
  • Numbness
  • Tendon inflammations and related conditions, such as bursitis, tenosynovitis, etc.[4]
  • Nerve compression disorders, such as carpal tunnel syndrome[4]
  • Osteoarthritis[4]
  • Thoracic outlet syndrome
  • Inability to work or execute daily function

Management / Interventions[edit | edit source]

Interventions:

Resistance training[1]

  • According to the research, individualized resistance training specific to the pain affected area has positive effect to the pain intensity
  • Elastic resistance exercises
  • Progressive training with variable resistance and/or contraction type and speed

Motor control training[1]

  • Isolated dynamic joint mobility movements
    • Slow speed (15-30 seconds/repetitive)
  • Target the site of pain


Posture modification

Manual therapy

  • Should be conducted by physiotherapists based on individual's condition

Management

Job modifications
Pain relief by using prescribed medication

Search for professionals such as physiotherapists for advice
