Musculoskeletal Assessment

Musculoskeletal System
Articulation of two or more bones
Functions of the Musculoskeletal System
~Provides structure, support and movement for the body
~Allows the body to maintain posture and position
~Supports and protects organs and soft tissues
~Guards entrances and exits to digestive and urinary systems
~Produces red blood cells- hematopoiesis
~Stores fat and minerals
~Generates heat
Is composed of 206 BONES; Provides support for the soft tissue and organs of the body
Types of Bones:
~Long (femur)
~Short (tarsals)
~Flat (sternum)
~Irregular (skull)
Connect BONE to BONE
Skeletal Muscles
Composed of fibers and tendons
Connect BONE to MUSCLE
Non-synovial joints
Non-movable or slightly movable joints
Ex: Sutures of skull and vertebrae
Synovial joints
Movable joint lubricated by synovial fluid
Bending a limb at the joint
Straightening a limb at a joint
Moving the head around a central axis
Moving the arm or leg in a circle around the shoulder or hip
Raising a part of the body
Lowering a part of the body
Moving a body part foward and parallel to the ground (FROWNING)
Moving a body part backward and parallel to the ground (SMILING)
Moving a limb AWAY from the body
Moving a limb TOWARD the body
Turning the forearm so that the palm is DOWN
Turning the forearm so that the palm is UP
Moving the plantar surface(sole) of the foot INWARD at the ankle
Moving the plantar surface (sole) of the foot OUTWARD at the ankle
Need for FULL MS Assessment
If patient has COMPLAINTS, DISEASE or difficulty ADLs
Screening/Mini Assessment
~Inspection/palpations of major joints and muscles
~Functional ROM
~Muscle strength in arms and legs
Objective Data
~Ensure patient is comfortable
~Use a CEPHALOCAUDAL approach (Head to Toe)
~Always COMPARE WITH THE OPPOSITE SIDE (unaffected side)
~Assess painful areas LAST
~Swelling (Edema)

Homan's sign
Very unreliable but gives a way to assess for blood clot in the lower extremity

Assessment for Deep Vein Thrombosis (DVT) - the most common in the leg
Lifespan Consideration: Newborns
~Flat feet
~Check spine
~Physician or Nurse Practitioner assess hips for congenital hip dislocation until age 1- Ortolani's maneuver
Lifespan Considerations: Children
~Ligaments are stronger than bones
~Age 4 changes to knock knees and usually resolves in late childhood or early adolescence
~Screening (Scoliosis) - starts in middle school (age 11 or 12)
Lifespan Considerations: Pregnant Female
~Softened cartilage in the pelvis and increased mobility of the joints
~Lordosis (common)
~Shift in center of gravity
Lifespan Considerations: Older adults
~Decreased muscle mass, tone, strength
~Decrease cartilage
~Decreased bone density
~Changes in mobility and endurance
Men vs Women Considerations
~Men muscles are bigger, bones are more dense
~Women are more flexible, bone is less dense
Psychosocial Considerations
Mental health problems may promote inactivity or isolation; Health probelms may trigger mental health issues
Cultural Considerations
African Americans have higher bone density than Europeans; Europeans have higher bone density than Asians
Risk Factor Considerations for MS Disease
~Family History (Congenital Abnormalities)
~Arthritis (Rheumatoid or Osteoarthritis)
~Activity (Lifestyle, tobacco, chronic illness and medication therapy)
~Nutrition (Diet, Weight)
Nursing Diagnosis R/T MS Disorders
~Impaired physical mobility
~Risk for potential for impaired neurovascular assessment
~Activity intolerance
~Acute or chronic pain
~Self-care deficit
~Risk for injury
~Impaired elimination pattern
