Managing Mobility Problems: A Comprehensive Approach
The most effective approach to managing a patient with mobility problems involves standardized assessment using validated tools like the Timed Up and Go (TUG) test and 4-Stage Balance Test, followed by implementation of a multicomponent exercise program that includes balance training, strength training, gait training, and aerobic exercise. 1, 2
Assessment and Screening
Initial Mobility Evaluation
- Use validated screening tools:
- Timed Up and Go (TUG) test: Patient rises from chair, walks 3 meters, turns, returns to chair, and sits down. Time >12 seconds indicates increased fall risk 1
- 4-Stage Balance Test: Patient stands in 4 increasingly challenging positions for 10 seconds each (feet side by side, semitandem stand, tandem stand, single-foot stand). Inability to hold tandem stand for 10 seconds suggests increased fall risk 1
- Three key screening questions: 1) Have you fallen in the past year? 2) Do you feel unsteady when standing/walking? 3) Are you worried about falling? 1, 2
Identify Contributing Factors (P-SCHEME)
- Pain (axial or lower extremity)
- Shoes (suboptimal footwear)
- Cognitive impairment
- Hypotension (orthostatic or iatrogenic)
- Eyesight (vision impairment)
- Medications (centrally acting)
- Environmental factors 1
Intervention Strategies
Exercise Interventions
- Balance training: Tai chi, standing exercises with progressively reduced base of support
- Strength training: Focus on lower extremity muscles with 3 sets of 8-10 repetitions at 50-70% of 1 repetition maximum 2
- Gait training: Walking with proper technique, navigating obstacles
- Aerobic exercise: Walking, stationary cycling
Medication Review
- Evaluate medications that may contribute to mobility problems, particularly centrally acting medications 1, 3
- Be cautious with medications like baclofen that may cause sedation and affect balance 3
- Consider polypharmacy (≥5 medications) as a risk factor for mobility problems 1
Assistive Devices
- Provide appropriate mobility aids based on assessment:
- Canes for mild balance impairment
- Walkers for moderate balance/strength issues
- Wheelchairs for severe mobility limitations 2
- Ensure proper fitting and training in the use of assistive devices
Environmental Modifications
- Home safety assessment and modifications:
- Remove tripping hazards
- Install grab bars in bathrooms
- Improve lighting
- Consider ramps or stair lifts if needed 2
Special Considerations
Functional Neurological Disorders
For patients with functional movement disorders:
- Encourage optimal postural alignment at rest and during activities
- Promote even weight distribution in sitting, transfers, standing, and walking
- Grade activities to increase use of affected limbs with normal movement patterns
- Avoid prolonged positioning of joints at end range 1
Cognitive Impairment
For patients with cognitive impairment affecting mobility:
- Simplify instructions and environment
- Establish predictable routines
- Consider underlying factors like pain, sensory changes, and caregiver communication style 1
Monitoring and Follow-up
- Schedule regular follow-up visits to assess progress
- Reassess balance and gait using standardized tests
- Adjust interventions based on progress and emerging issues 2
Common Pitfalls to Avoid
- Overlooking pain as a contributor: Always assess and manage pain that may limit mobility
- Focusing only on assistive devices: While helpful, they should complement rather than replace exercise interventions
- Neglecting psychological factors: Fear of falling can significantly limit mobility even when physical capacity exists
- Inappropriate splinting: May prevent restoration of normal movement and potentially worsen symptoms in some conditions 1
- Ignoring medication side effects: Some medications can cause sedation, orthostatic hypotension, or other effects that impair mobility 3
By systematically addressing mobility problems through comprehensive assessment and targeted interventions, clinicians can help patients maintain or improve their mobility, independence, and quality of life.
