Mobility and immobility

Mobility and Immobility

Definition

  • Mobility is defined as the freedom and independence to move purposefully within one's environment. It requires functional musculoskeletal and nervous systems.

  • Immobility is the inability to move freely and independently, leading to increased risk of complications with greater degrees and lengths of immobilization.

Sources of Mobility Limitations

Mobility can be categorized into types based on duration and onset:

  • Temporary: For instance, following procedures like knee arthroplasty.

  • Permanent: Such as cases of paraplegia.

  • Sudden Onset: Resulting from accidents like motor-vehicle crashes (e.g., fractures).

  • Slow Onset: Conditions like multiple sclerosis can gradually impair mobility.

Body Mechanics and Assessment

  • Effective movement relies on coordination across the musculoskeletal and nervous systems, utilizing principles of alignment, balance, gravity, and friction to ensure optimal mobility.

  • Assessments typically focus on:

    • Mobility

    • Range of Motion (ROM)

    • Gait analysis

    • Exercise status

    • Activity tolerance

    • Body alignment in varying positions (standing, sitting, lying).

Factors Affecting Mobility

Key factors that impact mobility include:

  • Alterations in muscle function.

  • Injuries to the musculoskeletal system.

  • Poor posture.

  • Impairments in the central nervous system.

  • General health status and age considerations.

Systemic Effects of Immobility

Integumentary System

  • Increased pressure can lead to skin breakdown and pressure injuries due to decreased circulation and metabolic alterations.

Respiratory System

  • Reduced respiratory movements can cause decreased oxygenation and gas exchange, contributing to atelectasis and hypostatic pneumonia due to stasis of secretions. The decrease in cough response can also exacerbate these complications.

Cardiovascular System

  • Immobility can result in:

    • Orthostatic hypotension

    • Decreased fluid volume in circulation

    • Blood stasis leading to thrombus risk and increased cardiac workload caused by reduced cardiac output.

Metabolic Changes

  • Immobility triggers alterations in the endocrine system, decreasing basal metabolic rates and leading to negative nitrogen balance, muscle loss, weight loss, and electrolyte imbalances.

Genitourinary and Gastrointestinal Systems

  • Genitourinary Effects:

    • Urinary stasis

    • Increased risk of renal calculi

    • Urinary tract infections due to decreased fluid intake and use of catheters.

  • Gastrointestinal Effects:

    • Decreased peristalsis and fluid intake leading to constipation and fecal impaction risks.

Musculoskeletal System

  • Consequences include:

    • Decreased muscle strength, endurance, and mass

    • Impaired balance leading to risks of falls

    • Muscular atrophy and alterations in calcium metabolism (frequency of osteoporosis and pathological fractures).

Psychosocial Effects of Immobility

Neurologic/Psychosocial Effects

  • Changes in emotional state (depression, anxiety)

  • Behavioral issues (withdrawal, hostility)

  • Ineffective coping mechanisms.

Developmental Considerations

  • Infants to Preschoolers: Slower gross motor and developmental skills;

  • Adolescents: Risk of social isolation, interrupted independence;

  • Adults: Physiological system alterations and identity concerns;

  • Older Adults: Increased risk of falls and injuries, along with coordination loss that affects mobility and independence.

Assessment and Care Management

Integumentary Assessment

  • Regular monitoring for skin breakdown, pressure injuries, and using scales to assess risk (Norton or Braden).

Nursing Interventions

  • Using corrective positioning devices, regularly turning patients, and ensuring proper nutrition (calories, proteins).

  • Skin and perineal care are crucial for maintaining skin integrity.

Respiratory Care Management

  • Maintain airway patency and promote lung expansion through regular positioning and physical therapy.

  • Client education on deep breathing exercises and hydration to mobilize secretions.

Cardiovascular Care and Thrombus Prevention

  • Monitor vital signs and activity levels, introducing antiembolic stockings and sequential compression devices to ensure venous return.

Elimination Care

  • Maintain urinary and bowel function through hydration, dietary adjustments, and bladder and bowel management practices.

Therapeutic Use of Heat and Cold

Heat Application Effects

  • Increases blood flow and muscle relaxation and helps in pain relief.

Cold Application Effects

  • Diminishes inflammation and pain, prevents swelling, and decreases body temperature.

Client Safety Considerations

  • Careful monitoring for heat/cold-related injuries especially among vulnerable populations (young, elderly).

  • Ensure instructions and protocols are followed for applying heat/cold therapy.

Client Education and Involvement in Care

Promoting independence and active participation in care plans and rehabilitation, emphasizing the importance of understanding mobility techniques, use of assistive devices, and maintaining social engagement throughout the recovery process.
