Synovial joint

Ball and Socket Joint (hip)


Fibrous tissue that connect ones an cartilages


Connect muscle to bone


Nonvascular, supporting tissue (joints and thorax)

concentric tension

Increased muscle contraction causes muscle shortening resulting in movement

Eccentric tension

Helps control the speed and direction of movement

Isotonic contraction

39. is the maximum amount of movement available at a joint in one of the three planes of the body: sagittal, frontal, or transverse


particular manner or style of walking

Exercise and activity tolerance

physical activity for conditioning the body, improving health, and maintaining fitness

Trochanter roll

prevents external rotation of the hips when the client is in supine position

Describe how you would assist clients with hemiplegia or hemiparesis

Always stand on the client's affected side and support the client by using a gait belt.

Identify the evaluative measures in mobility

the client's ability to maintain or improve body alignment, improve mobility; protect the client from the hazards of immobility

What is a potential hazard that you should assess when the client is in a prone position


joint contracture

Abnormal and usually permanent condition of a joint, characterized by flexion and fixation and caused by disuse, atrophy, and shortening of muscle fibers.

anthropometric measurements

Measures of height, weight, and skinfold thickness to evaluate muscle atrophy.

disuse osteoporosis

A decline is bone density that is associated with impaired mobility or immobilization of an extremity because of fracture, paralysis, or bone or joint inflammation.


A foreign object, a quantity of air or gas, a bit of tissue or tumor, or a piece of thrombus that circulates in the bloodstream until it becomes lodged in a vessel.

gait belt

Leather belt that encircles the waist and has handles attached for the nurse to hold.

muscle atrophy

Loss of muscle tissue.

negative nitrogen balance

Condition occurring when the body excretes more nitrogen than it takes in.


Not hardened, soft.

chest physiotherapy (CPT)

Group of therapies used to mobilize pulmonary secretions.


Paralysis of one side of the body.


Muscular weakness of one half of the body.

Body mechanics are the coordinated efforts of the

musculoskeletal and nervous systems as the person moves, lifts, bends, stands, sits, lies down, and completes daily activities

Findings from evidence-based nursing research about safe client handling prevents

injuries to nurses and clients when moving and transferring clients

The skeletal system provides bony support structure for

movement, attachment of ligaments and muscles, protection of vital organs, some of the regulation of calcium, and production of red blood cells.

The nervous system provides

initiation and voluntary control of movement

Coordination and regulation of muscle groups depend on

muscle tone; activity of antagonistic, synergistic, and antigravity muscles; and neural input to muscles

Body alignment is the condition of

joints, tendons, ligaments, and muscles in various body positions.

Balance occurs when there is a wide base of

support, the center of gravity falls within the base of support, and a vertical line falls from the center of gravity through the base of support.

Developmental stages influence

body alignment and mobility; the greatest impact of physiological changes on the musculoskeletal system is observed in children and older adults.

The risk of disabilities related to immobilization depends on

on the extent and duration of immobilization and the client's overall level of health.

Immobility sometimes results from

illness or trauma or is prescribed for therapeutic reasons.

Immobility presents hazards in

the physiological, psychological, and developmental dimensions.

The nursing process and critical thinking assist in providing

care for clients who are experiencing or are at risk for the adverse effects of impaired body alignment and immobility.

Clients with impaired body alignment require nursing interventions to

maintain them in the supported Fowler's, supine, prone, side-lying, and Sims' positions.

Client movement algorithms serve as

assessment tools and guide safe client handling and movement.

Appropriate friction-reducing assistive devices and mechanical lifts need to be used for

client transfers when applicable.

No-lift policies benefit

all members of the health care system: clients, nurses, and administration.

Range-of-motion exercises include

one or all of the body joints
