Module 10 - MSK Assessment Flashcards
Structure of MSK System
- Bones
- Joints
- Cartilage
- Ligaments
- Bursa
- Muscles (Skeletal, Smooth, Cardiac)
Function of MSK
- Supports the body
- Calcium storage
- Movement
- RBC production
- Protection of the organs
Primary Muscles terminology
- Fasciculi - bundles of fibers
- Tendons - attached to bone
Movement terminology for muscles
- Flexion
- Extension
- Abduction
- Adduction
- Pronation
- Supination
- Circumduction
- Eversion
- Rotation
- Protraction
- Retraction
- Elevation
- Depression
Spinal structures - Terminology
- Vertebrae
- Spinal process (C7 - L4)
- Invertebrate discs
Shoulder structure - Terminology
- Glenohumeral joint (ball and socket)
- Rotator cuff
- Subacromial bursa – Assists during abduction of the arm
- Acromion process – Very top of the shoulder
- Great tubercle of humerous – Second bump of the humerous
- Coracoid process – Surrounds the joint of the scapula
Structure of Elbow - Terminology
- Humers
- Radius
- Ulna
Structure of Wrist/Carpal joints - Terminology
- Radiocarpal joint – articulation of the radius (thumb side)
- Midcarpal joint - involved in Flexion, Extension, some rotation
- Metacarpophalangeal/Interphalangeal joints - Finger extension
Structure of the Knee - Terminology
- Femur
- Tibia
- Patella (kneecap)
- Largest joint in the body
Structure of Ankle/foot
- Terminology
- Tibiotalar joint – articulation of the tibia, fibula and talus – hinge joint limited to flexion and extension
- Medial/lateral malleolus – bony prominence that promote stability if the ankle joint
Health History of MSK
1) Joint pain/problems
2) Knee joint
3) Muscles
4) Bones
5) Function Assessment (ADL’s)
6) Self-Care behaviors
How do we test active ROM?
- Voluntary movement, performing the movements on your own
- Appropriate control
- Stabilized
- Recognizing limitations
How do we test passive ROM?
- Limited movements that may require assistance
- Muscles are relaxed when you move the body
- Anchor the joint with one hand while your other hand slowly moves to its limit
Process of Rating Muscle Strength
- Instruct the patient to repeat the motions you tested for active ROM
- Ask the patient to flex (tighten/contract) the muscle and hoe as you apply opposing force
- Muscle strength should be equal bilaterally
Muscle grading scale
5 – Full ROM against gravity, full resistance - Normal
4 – Full ROM against gravity, some resistance - Assessment good
3 – Full ROM with gravity - Assessment fair
2 – Full ROM with gravity eliminated - Assessment is poor
1- Slight Contraction - Assessment is trace
0 - No Contraction - Assessment is zero
Inspection - Normal Findings
- Size
- Joints
- Contour
- Muscle tone
- Smooth skin
- Even tone
- Noting deformities, masses, swelling and discoloration
Inspection - Abnormalities
- Swelling
- Deformities
- Lesions
- Abrasions
- Scar tissue
- Contracture
- Dislocations
- Discoloration
Palpation - Normal findings
- Even skin texture
- Temperature
- Moisture
- Muscles
- Bony articulations
- Area of the joint
- Should not feel synovial fluid
