P5 - Balance Rehabilitation Flashcards
What is balance in the context of human movement?
Balance is the ability to maintain an upright posture and move from one posture to another against gravity, keeping the body in equilibrium whether at rest or in steady-state motion.
What is the Base of Support (BOS)?
The Base of Support (BOS) is the area of the object that is in contact with the supporting surface.
What is the Centre of Mass (COM) in human movement?
The Centre of Mass (COM), or centre of gravity, is a point located at the centre of the total body mass.
How is balance maintained in relation to the Base of Support (BOS)?
Balance is the ability to maintain the Centre of Mass (COM) within the limits of the Base of Support (BOS).
Which body systems contribute to maintaining balance?
Somatosensory system (afferent/efferent pathways)
Muscle strength and range of motion (ROM)
Vestibular system
Vision
Proprioception
Cognition
What are common causes of reduced balance?
Frailty and ageing
Neurological conditions (e.g., stroke, Parkinson’s disease, multiple sclerosis)
Vestibular conditions (e.g., BPPV, labyrinthitis)
Diabetes and peripheral neuropathies
Sarcopenia or muscular atrophy
Injury, trauma, or pain
What biopsychosocial factors contribute to balance issues and falls?
Loss of confidence
Reduction in physical activity
Environmental hazards
How does the World Health Organization (WHO) define a fall?
A fall is an event resulting in a person unintentionally coming to rest on the ground, floor, or a lower level. It excludes major internal events (e.g., stroke) or being hit by an external force.
What are the two main causes of falls?
Medical cause (e.g., collapse due to health conditions)
Mechanical cause (e.g., tripping over an object)
What are some key risk factors for falls in frail older adults?
Previous falls (one of the highest risk factors)
Older adults should be routinely asked about falls in the past year (NICE Guidelines 2019)
What percentage of falls lead to major injuries such as lacerations, traumatic brain injuries (TBIs), or fractures?
About 40-60% of falls lead to major injuries, including lacerations, TBIs, or fractures.
What is recommended for older adults who seek medical treatment after a fall?
They should undergo a risk assessment, including gait analysis and balance testing. Multifactorial falls risk assessments should also be offered (e.g., at multidisciplinary falls clinics).
What are intrinsic and extrinsic risk factors for falls?
Intrinsic: Medical conditions, visual impairments, polypharmacy, balance deficits, weakness
Extrinsic: Environmental hazards, poor lighting, uneven surfaces, pets
What are some common outcome measures for assessing balance?
BERG Balance Scale
Tinetti test
Romberg test
Functional reach test
BESTest
What are some common outcome measures for assessing mobility and gait?
Timed Up and Go (TUG) test
Turn-180 test
Lindop Mobility test
10-metre walk test
30-second sit-to-stand test
