- Fall Prevention(also: Fall Risk Reduction, Falls Prevention)
- Strategies, interventions, and technologies designed to reduce the risk of falls, particularly among older adults and people with mobility or balance impairments. Falls are a leading cause of injury, hospitalization, and loss of independence in aging populations. Fall prevention…
- Fractionation(also: Finger Fractionation, Finger Independence)
- The ability to move individual fingers independently of one another, a key measure of fine motor control assessed in stroke rehabilitation. After a stroke, patients often lose fractionation, meaning that attempting to move one finger causes involuntary coupled movement in…
- Functional Capacity(also: Functional Ability)
- The maximum level at which a person can perform a given physical or cognitive activity under standardised conditions. Functional capacity represents what a person is capable of doing, as opposed to what they typically do in daily life (functional performance). In assistive…
- Functional Electrical Stimulation(also: FES)
- A rehabilitation technique that uses low-level electrical currents to activate paralyzed or weakened muscles in people with neurological conditions such as spinal cord injury, stroke, or multiple sclerosis. Electrodes placed on the skin or implanted near motor nerves deliver…
- Functional Limitation(also: Functional Restriction)
- A restriction or lack of ability to perform a physical or cognitive action in the manner or within the range considered typical. In the context of accessibility and rehabilitation, functional limitations are the specific constraints on what a person can do — such as limited grip…
- Functional Vision(also: Functional Visual Ability)
- How well a person uses their residual vision to perform routine tasks under various conditions throughout the day. Functional vision goes beyond clinical measures like visual acuity to assess practical visual ability in real-world contexts — such as reading, identifying objects,…
