Gait disturbances in the acute medically ill elderly

Area of Science:

• Geriatrics
• Neurology
• Internal Medicine

Background:

• Acute non-neurological diseases can precipitate functional decline.
• Elderly patients are particularly vulnerable to mobility impairments during acute illness.
• Assessing movement disorders requires considering underlying medical conditions.

Purpose of the Study:

• To characterize acute deterioration in truncal movements, posture, and gait.
• To identify factors associated with reversible gait abnormalities in non-neurological illness.
• To define an 'at risk' subgroup of elderly patients experiencing mobility loss.

Main Methods:

• Observational study of patients admitted with acute non-neurological disease.
• Assessment of gait, truncal movements, posture, and mental status.
• Correlation analysis between gait dysfunction and other clinical measures, including activities of daily living scores and upper limb apraxia tests.

Main Results:

• Reversible gait abnormalities resembling 'lower-half parkinsonism' were linked to axial movement disorders, disability, and low cognitive scores.
• Gait dysfunction showed no association with upper limb apraxia.
• An 'at risk' subgroup of elderly patients was identified, characterized by loss of walking independence and difficulties with axial movements during acute illness.

Conclusions:

• Acute medical illness can cause reversible gait and axial movement impairments, mimicking neurological conditions.
• Elderly patients experiencing acute illness may develop significant mobility and axial movement deficits.
• Clinical assessment of elderly patients must account for acute medical conditions as a cause of locomotor and axial movement impairment.
