MSPT - EXAM 2 Flashcards
(423 cards)
Common Repetitive Stress Injuries (RSIs)
Tendinopathy Thoracic Outlet Arthritis Peripheral nerve entrapment Myofascial pain syndromes Neck and back postural strain
What are workplace factors that lead to the development of MSDs?
Repetitive, forceful, or awkward movements over time
Prolonged bad posture
Reported cases of work-related injuries cost how much annually?
$54 billion
What is the most prevalent work-related MSD?
Carpal tunnel syndrome (2/3 of all work-related injuries)
Risk factors for carpal tunnel syndrome?
Prolonged wrist flexion/extension Repetitive gripping Repetitive ulnar deviation Repetitive pinching Repetitive supination Exposure to cold or vibration Mechanical compression
What is myofascial pain syndrome caused by?
Trigger points - bands in muscles that are tight and tender
Risk factors for RSI or CTD (cumulative trauma disorder)?
Repetitiveness Forces Posture (constrained/awkward) Vibration Psychological stress Workstation design Sedentary jobs Excessive alcohol Smoking Arthritis Poor nutrition Biomechanical alignment issues
What is Stage I RSI/CTD?
Some symptoms at work
Physical exam is essentially clear
What is Stage II RSI/CTD?
Symptoms begin earlier in the day and start to linger after work
Some difficulty doing job at normal pace
(+) exam findings
What is Stage III RSI/CTD?
Symptoms at rest or on days off
Activities outside of work are affected
Progressive disability
What is assessed during a task assessment?
Forces (using dynamometer) Time (hours working, how many breaks) Repetitions Task variety Body mechanics External support (ex: vibration gloves) Evaluate tools of job (ex: weight, grip width of hammer)
Effects of Forward Head Posture (FHP)?
Compression of upper CS Tension and shearing of lower CS Loss of lumbar lordosis Increase thoracic kyphosis Increased risk of disc pathology Shoulder girdle protraction (impingement) Stretch weakness in postural muscles Muscular trigger points Adaptive shortening of certain muscles (ex: subocipitals, pectoralis)
Workstation suggestions
Use wrist rest Lumbar support 90 deg elbow angle Thighs parallel to floor Feet on ground or footrest Use document holder VDT screen in direct line of sight Screen center 15 deg below horizontal
What are other important factors in prevention against RSI/CTD besides workstation design and posture?
Task diversity
Work pauses and rest periods
Physical fitness
Musculoskeletal and neuromuscular tissues require what 3 things to maintain health?
Normal biomechanical stresses (intermittent compression and unloading)
Movement
Unimpaired circulation
How can you be at risk for injury if you are in a correct posture?
If the posture is prolonged/static - no movement to maintain healthy tissue
How long should work pauses be?
Recommendations vary:
between 30 sec and 15 min per hour
What is the difference between a colles’ fracture and a smith’s fracture?
Colles’: extension fracture of radius (distal radius displaced dorsally)
Smith’s: flexion fracture of the radius (distal radius displaced anteriorly)
What age/gender is commonly affected by Colles’ fracture?
Post-menopausal women
What is the common mechanism of a colles’ fx?
FOOSH
What are the ways to immobilize a collies fx?
Rigid splint
Casting (in slight flexion)
ORIF
External fixator
Why are ADL’s limited after immobilization for colles’ fx is removed?
Pain
Poor grip
ROM impairments
Why is dynamic splinting a great tool for increasing ROM?
Keeps patient in low load prolonged stretch for hours - much longer than a PT session (TERT)
What are finger ladders good for?
Shoulder flexion ROM
Elbow and wrist extension ROM
Finger flexor and extensor activation
