Mobility
Question | Answer |
---|---|
Mobility definition | The ability to move freely, easily, rhythmically, and purposefully in the environment, is an essential part of living. |
What are human's base of support? | Feet on the ground |
Where does a human's line of gravity begin and end? | The top of the head, falls between the shoulders, through the trunk, slightly anterior to the sacrum, and between the weight-bearing joints and base of support. |
Line of gravity | An imaginary vertical line drawn through the body's center of gravity. |
Center of gravity | The point at which all of the body's mass is centered. |
Base of support | Foundation on which the body rests. |
Extensor muscles | Also known as antigravity muscles, carry the major load as they keep the body upright. |
Joints are considered...? | The functional units of the musculoskeletal system. |
Body movement require what four things? | Alignment, Joint Mobility, Posture, Balance |
What is osteoporosis | A condition in which the bones become brittle and fragile. |
What causes osteoporosis? | Inadequate Calcium and Vitamin D |
How does poor nourishment affect mobility? | May have muscle weakness and fatigue. Vitamin D deficiency causes bone deformity during growth. Inadequate calcium intake and vitamin D synthesis and intake increase the risk of osteoporosis. |
How does obesity affect mobility? | Can distort movement and stress joints, adversely affecting posture, balance, and joint health. |
Isotonic Exercise | Dynamic exercises in which the muscle shortens to contract. |
Isometric Exercise | Static or setting exercises in which muscles contract without moving the joint (squeezing a towel between the knees) |
Isokinetic Exercise | Resistive exercises that involve muscle contraction or tension against resistance. |
Aerobic Exercise | Involves large muscle groups. More oxygen is taken into the body than is used to perform the activity. (Running) |
Anaerobic Exercise | Used for endurance training. Muscles can't get enough oxygen from blood stream, so anaerobic pathways are used for short bursts of energy. (Weight Lifting, Sprinting) |
Musculoskeletal benefits of exercise | Size, shape, tone, and strength of muscles (including heart muscle). Increases joint flexibility, stability, and ROM. |
How is bone density and strength maintained? | With weight-bearing and high-impact movement. This maintains the balance between osteoblasts (builder cells) and osteoclasts (resorption and breakdown cells). |
Cardiovascular benefits of exercise | Increases cardiac efficiency (HR, output, BP, O2sat, cardiac strength) and reduces stress. |
Respiratory benefits of exercise | Improved pulmonary function (gas exchange, cerebral perfusion, decreased breathing effort, decreased risk for infection) |
Gastrointestinal benefits of exercise | Improved appetite and tone, which facilitates peristalsis and relieves constipation. |
Metabolic/Endocrine benefits of exercise | Elevates metabolism (anabolism and catabolism) and improves caloric use. Weight loss and exercise stabilize blood sugar and make cells more responsive to insulin. |
Urinary benefits of exercise | Blood flow increases so waste is excreted more effectively. Stagnant urine is avoided. |
Immune benefits of exercise | Improves lymph drainage. Moderate exercise enhances immunity. |
Psychoneuologic benefits of exercise | Elevates mood, relieves stress, anxiety, and symptoms of depression. Improves quality of sleep. |
Cognitive benefits of exercise | Improves cognition (decision-making, problem-solving, paying attention, and planning. Improves mood, learning, and performance) |
Spiritual benefits of exercise | Improves mind-body-spirit connection (usually with yoga-style exercises) with deep breathing, and contracting and releasing groups of muscles. |
Effects of immobility on the cardiovascular system | Diminished cardiac reserve. Orthostatic hypotension. Venous stasis and vasodilation. Dependent edema. Thrombus formation (DVT). |
Paresis | Muscle group that is paralized |
Spastic | Muscle group that has too much muscle tone |
Flaccid | Muscle group that has no muscle tone |
Effects of immobility on the respiratory system | Decreased respiratory movement. Pooling of respiratory secretions. Atelectasis. |
Effects of immobility on the musculoskeletal system | Disuse osteoporosis. Disuse atrophy (decrease in muscle size). Disuse contractures (permanent shortening of the muscle). Foot and wrist drop. Stiffness and pain in joints that can become ankylosed (permanently immobile). |
Effects of immobility on the metabolic system | Decreased metabolic rate. Negative nitrogen balance (catabolized muscle releases nitrogen). Anorexia. Negative calcium balance. |
Effects of immobility on the urinary system | Urinary stasis. Renal calculi. Urinary retention. Urinary infection. |
Effects of immobility on the gastrointestinal system | Constipation ---> Impaction. Use of the Valsalva maneuver. |
Valsalva maneuver | Places undue stress on the heart and circulatory system. Client holds breath and strains against a closed glottis, which builds pressure. When pressure is suddenly released, a surge of blood flows to the heart. |
Effects of immobility on the integumentary system | Reduced skin turgor (shifts in fluids between fluid compartments effect dermis and subQ tissues). Skin breakdown (pressure ulcers). |
Proper body mechanics | Lift no more than 35 pounds without assistance. Pull rather than push. Pivot to avoid twisting the spine. |
Examples of supportive devices | Suspension or heel guard boot (prevent foot drop and relieve heel pressure). Foot board. Abduction pillow. Hand roll (made with a washcloth; prevents contractures). |
Ways to prevent falls | Eliminate clutter, rugs, electrical cords. Be sure call light is accessible. Set bed alarm. Check on patient frequently. |
