Falls in the elderly related to postural imbalance
British Medical Journal
|January 29, 1977
Summary
Age-related sway increases, impacting elderly fall risk. Postural control declines with age and central nervous system diseases, particularly in women and those experiencing balance loss.
Area of Science:
- Gerontology
- Neurology
- Biomechanics
Background:
- Falls are a significant concern for the elderly population.
- Postural control is crucial for maintaining balance and preventing falls.
- Age and underlying health conditions can affect postural stability.
Purpose of the Study:
- To investigate the relationship between age, sex, and postural sway in elderly individuals.
- To identify factors contributing to falls in the elderly, including balance loss and specific triggers.
- To explore the influence of physiological aging and central nervous system diseases on postural control.
Main Methods:
- A study involving 243 elderly individuals (aged 60-96) and 63 younger subjects.
- Questionnaires were administered to assess fall history.
- Postural sway was measured in all participants.
Main Results:
- Postural sway increased with advancing age and was consistently higher in women.
- No significant difference in sway was found between individuals with no fall history and those who fell due to tripping.
- Sway significantly increased in both sexes due to loss of balance, and in women experiencing specific fall triggers like giddiness or rising from a chair.
Conclusions:
- Advancing age leads to a physiological decline in postural control.
- Diseases affecting the central nervous system further contribute to the deterioration of postural stability.
- Understanding these factors is crucial for developing fall prevention strategies in the elderly.

01:10Homeostatic Imbalance
Homeostasis is the maintenance of a stable internal environment within the body, which is crucial for the proper functioning of cells, tissues, organs, and organ systems. The body has various control mechanisms that work together to regulate various physiological parameters such as temperature, blood pressure, pH balance, and fluid balance, to name a few. These control mechanisms are based on feedback loops that can be either positive or negative.
However, sometimes these feedback loops fail,...

01:19The Effect of Aging on Tissues
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...
01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:15Equilibrium and Balance
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...
01:15Drug Dosing: Geriatric Patients
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...
01:27Pharmacodynamics in Geriatric Patients: Effects of Age
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...
