How can an exercise physiologist (EP) and a physiologist help a patient with osteopenia prevent falls?

Role of Exercise Physiologists and Physiologists in Fall Prevention for Osteopenia Patients

Exercise physiologists and physiologists should implement multicomponent exercise interventions incorporating dynamic weight-bearing, strength and balance training 2-3 days per week for at least 10 weeks to reduce fall risk in patients with osteopenia. 1

Multifactorial Falls Risk Assessment

Before implementing interventions, a comprehensive falls risk assessment should be conducted:

• Key screening questions:

  • History of falls within the past 12 months
  • Feeling unsteady while walking or standing
  • Fear of falling 1, 2

• Physical assessment components:

  • Gait and mobility evaluation using Timed Up and Go test (>12 seconds indicates increased fall risk) 1, 2
  • Balance assessment using Four-Stage Balance Test (inability to hold tandem stand for 10 seconds indicates fall risk) 2
  • Lower limb strength testing 1
  • Evaluation of cognitive capacity that might affect balance 1, 2
  • Assessment of footwear and environmental hazards 1

Evidence-Based Exercise Interventions

1. Multicomponent Exercise Program

• Frequency: 2-3 sessions per week for at least 10 weeks 1
• Duration: Sessions of sufficient length to address all components (typically 45-60 minutes)
• Components:
  • Dynamic weight-bearing exercises
  • Progressive resistance training focusing on muscle power
  • Balance training
  • Functional training 1

Research shows this approach can reduce fall risk by up to 23% compared to usual care 1 and significantly improve balance measures by 10-71% in osteopenic women 3.

2. Progressive Resistance Training

• Focus on developing muscle power (speed of contraction) rather than just strength 1
• Target key muscle groups:
  • Hip muscles (abductors, adductors, external rotators)
  • Quadriceps
  • Trunk extensors 3, 4
• Gradually increase resistance as strength improves 1

A randomized controlled trial demonstrated improvements of 9-23% in strength of these muscle groups in osteopenic women 3.

3. Balance-Specific Training

• Include both static and dynamic balance exercises:
  • Static: Single-leg stance, tandem stance
  • Dynamic: Walking on different surfaces, stepping over obstacles
  • Functional: Sit-to-stand transitions, reaching activities 5

A 12-month balance training program showed significant improvements in Berg Balance Scale scores and reduced falling frequency in women with osteoporosis 5.

4. Spinal Extensor Strengthening

• Prioritize axial strength and stability exercises
• Implement progressive resistance for back extensors
• Consider a structured approach like the Spinal Proprioception Extension Exercise Dynamic (SPEED) program 4

This approach has been shown to improve back extensor strength, increase physical activity levels, and reduce back pain and fear of falling 4.

Implementation Strategies

1. Individualized Assessment and Prescription:

   • Use standardized tools to assess baseline function
   • Tailor exercise prescription using the FITT-PRO approach (Frequency, Intensity, Type, Time, and Progression) 1
   • Consider patient preferences and capabilities 6

2. Supervised Initial Training:

   • Provide direct supervision until patients can safely perform exercises independently
   • Ensure proper technique to prevent injury 1

3. Home Exercise Program:

   • Develop a complementary home exercise regimen
   • Provide clear written and visual instructions
   • Implement regular follow-up to ensure adherence and proper technique 7

4. Environmental Assessment:

   • Evaluate home environment for fall hazards
   • Recommend modifications as needed 1

5. Progression Planning:

   • Establish clear progression criteria
   • Regularly reassess and adjust program difficulty 1

Additional Considerations

• Nutritional Support: While evidence for vitamin D supplementation alone is mixed, ensure patients maintain adequate calcium and vitamin D intake according to country-specific recommendations 1

• Lifestyle Modifications: Advise on smoking cessation and moderate alcohol consumption, as both factors negatively impact bone health and increase fall risk 1

• Monitoring: Regularly reassess fall risk and exercise performance using standardized tools to track progress and adjust interventions 2

• Multidisciplinary Approach: Coordinate with other healthcare providers for medication reviews and additional interventions as needed 1

By implementing these evidence-based strategies, exercise physiologists and physiologists can significantly reduce fall risk and potentially improve bone mineral density in patients with osteopenia, ultimately reducing fracture risk and improving quality of life.
