Summary
Most institutionalized elderly residents have knee flexion contractures (KFCs), often unilateral. KFC severity correlates with impaired ambulation, cognitive issues, and knee pain, suggesting physical therapy interventions.
Area of Science:
- Gerontology
- Rehabilitation Medicine
- Orthopedics
Background:
- Knee flexion contractures (KFCs) are common in institutionalized elderly.
- Limited data exists on KFC prevalence, severity, and progression in this population.
Purpose of the Study:
- To determine the prevalence, severity, and progression of KFCs in institutionalized elderly individuals.
- To identify factors associated with knee extension and contracture development.
Main Methods:
- 112 nursing home residents with varying ambulation and cognitive abilities were assessed.
- Data collection occurred at baseline (T1) and after 10 months (T2).
Main Results:
- A majority of residents had unilateral KFC; only 25% had full bilateral extension.
- KFCs greater than 20 degrees were linked to nonambulation and resistance to motion.
- Changes in KFC (increase or decrease) correlated with increased resistance to passive motion.
Conclusions:
- Significant correlations exist between KFC degree and resistance to motion, cognitive impairment, impaired ambulation, and knee pain.
- Physical therapy may benefit nonambulatory residents with resistance to motion, those nearing 20-degree KFC, and ambulatory residents with developing contractures and ambulation decline.
