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.

Knee Joint
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

Alterations in Muscle Tone ll
Alterations in muscle tone are common manifestations of neurological disorders and reflect dysfunction within different nervous system regions. Spasticity, paratonia, and dystonia represent distinct forms of hypertonia, each with unique mechanisms, clinical features, and diagnostic importance.CharacteristicsSpasticity happens from upper motor neuron lesions and is characterized by velocity-dependent resistance to passive movement. Clinical features include:Exaggerated deep tendon reflexesClonus...
Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
