Lesson 24.1: Mobility

Define and Describe the Concept of Mobility

Mobility is defined as a state or quality of being mobile or movable. It is crucial in nursing practice as it directly affects patients' overall health and quality of life. In the context of mobility, several terms are often encountered, including:
  - Immobility: A state wherein an individual cannot move freely or adequately.
  - Disuse Syndrome: A condition that arises when there is a decrease in muscle strength and functional ability due to lack of use.
  - Deconditioned: A state resulting from a decline in physical fitness, often due to prolonged inactivity or illness.

Scope of Mobility

Mobility encompasses a wide scope, ranging from:
  - Full Mobility: The ability to move freely and without limitations.
  - Partial Mobility: Restrictions in movement, often requiring assistance or adaptive measures.
  - Complete Immobility: Inability to move or perform voluntary movements.

Review of Musculoskeletal System Anatomy and Physiology

The musculoskeletal system consists of:
  - Muscles: The tissues responsible for movement.
  - Bones: The structural framework that supports the body and protects internal organs.
  - Joints: The connections between bones that facilitate movement.

Additionally, the neurologic system plays a significant role in mobility by affecting muscle control and coordination.

Consequences of Immobility

Immobility can lead to several serious health complications, including:
  - Cardiovascular Complications: Such as increased risk for deep vein thrombosis (DVT) and decreased cardiovascular endurance.
  - Respiratory Complications: Including pneumonia and atelectasis due to shallow breathing and reduced lung expansion.
  - Musculoskeletal Complications: Presenting as muscle atrophy, weakness, and joint stiffness.
  - Integument System Issues: Such as pressure ulcers resulting from prolonged pressure on skin areas.
  - Gastrointestinal Complications: Including constipation and decreased appetite due to inactivity.
  - Urinary Complications: Risk for urinary retention and urinary tract infections (UTIs).
  - Psychological Effects: Such as depression, anxiety, and social isolation.

Notice the Risk Factors for Impaired Mobility

Individual Risk Factors

Several factors contribute to impaired mobility, including:
  - Traumatic Injury: This may involve injuries to the brain, spinal cord, bones, joints, or muscles.
  - Neurological Conditions: Diseases such as multiple sclerosis, stroke, or Parkinson's disease that impair motor function.
  - Chronic Conditions: Long-term health issues such as arthritis, diabetes, or heart disease, along with their treatment interventions that may lead to decreased mobility.

Recognize When an Individual Has Compromised Mobility

Elements of Musculoskeletal Assessment

To assess compromised mobility, healthcare professionals consider:

  • History: Collecting data from past medical history, family history, current medications, lifestyle behaviors, occupation, social environment, and problem-based history.

Common Symptoms Associated with Altered Mobility

Patients may exhibit:

  • Pain: Restrictions of movement may cause discomfort or pain.

  • Reduced Joint Movement: Limitations in movement range at affected joints.

  • Reduced Sensation or Loss of Sensation: Neurological impairments that lead to sensory deficits.

  • Falls: Increased risk due to balance issues or weakness.

  • Fatigue: General tiredness that affects activity levels.

  • Altered Gait or Imbalance: Observable changes in walking patterns and stability.

  • Reduced Functional Ability: Impaired capability to perform daily activities.

Diagnostic Tests

Various diagnostic tests used to assess mobility include:

  • Radiographic Tests:
      - X-ray: Imaging technique to view bone fractures and deformities.
      - MRI: Utilized to view soft tissue structures and assess joint health.
      - CT Scans: For detailed cross-sectional images of the body.
      - Bone Scan: Used to evaluate bone density and detect inflammation or infection.
      - Bone Mineral Density: Measurement to assess osteoporosis risk.
      - Myelogram: Imaging of the spinal canal and nerve roots.
      - Arthrography: Imaging of joint structures.

  • Other Diagnostic Tests:
      - Arthroscopy: A minimally invasive procedure to visualize and treat joint problems.
      - Electromyography: Measures electrical activity in muscles to assess nerve damage.
      - Blood Tests: Used to check for inflammation, infection, and other markers.
      - Analysis of Joint Fluids: To diagnose joint disorders.
      - Pathologic Analysis of Biopsied Tissue: Examination of tissues for abnormal cellular activity.

Provide Appropriate Nursing and Collaborative Interventions to Optimize Mobility and Minimize Complications of Immobility

Clinical Management

Primary Prevention measures to support mobility include:

  • Regular Physical Activity: Encouraging consistent movement to maintain strength and endurance.

  • Protection Against Injury: Implementing safety measures to prevent falls and injuries.

  • Optimal Nutrition: Focusing on a balanced diet to support overall health and mobility.

  • Fall Prevention Measures: Strategies to minimize fall risk, including environmental modifications and patient education.

Secondary Prevention focuses on screening:

  • Osteoporosis Screening: Adhering to national guidelines for screening to identify at-risk individuals.

  • Fall Assessment Screening: Utilizing screening tools to evaluate risk factors and implement necessary interventions at appropriate times.

Collaborative Interventions

  1. General Care Guidelines for Immobilized Patient:
       - Frequent turning, positioning, and alignment to promote circulation and prevent pressure ulcers.
       - Skin assessment and care to maintain skin integrity.
       - Implementing range of motion exercises to preserve joint function.
       - Encouraging deep breathing exercises to prevent respiratory complications.
       - Promoting weight-bearing activities when possible to strengthen bones and muscles.
       - Ensuring measures to optimize elimination are in place to prevent urinary retention.
       - Nutritional support to enhance recovery and health.

  2. Exercise Therapy:
       - Ambulation: Assisting patients in walking to enhance functional mobility.
       - Joint Mobility: Promoting exercises that facilitate movement at joints.
       - Stretching: Encouraging stretching exercises for flexibility and range of motion.
       - Balance: Implementing balance training to reduce fall risk.

  3. Pharmacologic Agents:
       - Administration of anti-inflammatory agents, analgesics, muscle relaxants, and nutritional supplements to support recovery and alleviate discomfort.

  4. Surgical Interventions:
       - Curative vs. Palliative: Differentiating between interventions aimed at curing conditions versus those that alleviate symptoms without addressing the underlying cause.

  5. Immobilization Devices:
       - Use of casts, splints, braces, traction, slings, shoulder immobilizers, and pillows to maintain joint position and support healing.
       

  6. Assistive Devices and Patient Handling Technology:
       - Incorporation of crutches, canes, walkers, wheelchairs, and prostheses to assist patients with mobility.
       

  7. Other Therapies: Exploring additional therapeutic options that may support mobility and health.
