Discuss special considerations for patients with alzheimer’s and/or dementia:

A
  • Perception and interpretation of the environment significantly altered
  • Persons affected by the amount, type and variety of stimuli found in the environment
    • Under and Over stimulation can lead to confusion, illusions , frustration and agitation
  • Changes in visual ability typical
    • Dementia-associated fall risk may be reduced by choosing floor coverings/carpeting that avoid patterns or borders that increase visual-spatial difficulties
    • strong color contrast can enhance functional ability by highlighting environmental features between floors and walls, chairs and flooring, and even utensils and tabletops, thereby facilitating more meaningful interpretation of the environment.

Q

Age-related changes in the axial skeleton are common and include the following (4 items):

A
  • Forward head position and rounded shoulders
  • Increased thoracic kyphotic curvature (hyperkyphosis)
  • Increased knee flexion angle
  • A more posterior hip position (Balzini, et al., 2003)
90
Q

In the extremities, the most common postural variations in aged adults are:

A
  • rounded shoulders with protracted scapula and slightly flexed elbows, hips, and knees.
  • changes in the articular surfaces and joint capsules often cause varus or valgus deformities at the hips, knees, or ankles.
  • The normally obtuse angle between the neck and shaft of the femur may become more acute, which emphasizes the flexed posture.
91
Q

Coordination is:

A
  • The ability to execute smooth, accurate, controlled movements, which is dependent on an intact neuromusculoskeletal system; inputs from visual, somatosensory, and vestibular systems; and sensorimotor processing.
92
Q

Normal coordination related impairments in aging:

A
  • slower eye-hand coordination
  • decreases in:
    • interlimb coordination
    • homolateral (same side) hand and foot movements
    • motor coordination
    • manual dexterity.
93
Q

Postural stability in normal healthy adults is affected by the availability and validity of:

A
  • visual, vestibular, haptic, and proprioceptive information that can provide a referential context for updating the body’s location in space.
94
Q

Age-related changes which may contribute to postural control and stability problems:

A
  • Impairment/loss in:
    • visual and vestibular information
    • muscular atrophy
    • loss of proprioception and vibration sense
    • extrapyramidal dysfunction
    • slowed reaction times
    • decreases in muscle strength and power
    • hyperkyphosis
95
Q

Aging process in the extrapyramidal systems may produce:

A
  • slowing of skilled motor movements
  • alterations of gross movements
  • The basal ganglia and cerebellum play a major role in control of movement.
    • Tics or tremors may become evident, and movement may be slowed (bradykinesia), altered or absent, leading to postural instability in the older adult
96
Q

What is likely the primary factor leading increased reaction time in older adults?

A
  • Slowed central processing
    • rather than other factors such as decreases in motor or sensory nerve conduction velocities or rate of muscle contraction.
97
Q

True or false:

Regular physical activity has no effects on age-related decreases in proprioception

A

False:

Regular physical activity may attenuate age-related decreases in proprioception

98
Q

The most typical gait changes with aging are the following:

A
  • Decreased step length
  • Decreased stride length
  • Slower walking velocity
  • Decreased cadence
  • Decreased ankle range and push-off
  • Increased double-stance time
  • Decreased vertical displacement of center of mass
99
Q

for Static Posture Assessment use:

A

plumb line

100
Q

Postural sway, small oscillating movements of the body over the feet during bipedal standing, can be assessed by:

A
  • observation
  • computer-assisted postural sway analyzers
  • force platforms
101
Q

The most common clinical approach to evaluating coordination in the older adult is to:

A

Observe the performance of functional movements and activities and the resultant movement characteristics.

102
Q

When assessing coordination the following should be considered:

A
  • the accurate ability to perform the task and the speed required to complete the task
  • Movement should be in the correct direction, and the movement trajectory should be smooth and fluid and well timed throughout.
  • problems with muscle tension and movement control achieved by groups of muscles working together (synergies) and dfficulty initiating or stopping the movement should be noted.
  • Body or extremity posture should be maintained during the movement
  • movements should be easily reversed, even with changes in speed and direction of movement
103
Q

Inability to maintain an upright posture without visual input is referred to as:

A
  • a positive Romberg sign.
104
Q

[Four] Standardized assessments of arm-hand function and motor coordination, and eye-hand coordination for use in older adults include the:

A
  • Purdue Pegboard Test
  • Jebsen Hand Function Test
  • Timed Manual Performance
  • Upper Extremity Performance Test for the Elderly (TEMPA)
105
Q

Balance in the older adult is assessed clinically using a variety of balance measures that evaluate the following areas:

A
  1. Static balance—standing quietly
  2. Limits of stability
  3. Anticipatory postural control
  4. Reactive postural control
  5. Sensory strategies and integration
  6. Functional balance skills
  7. Effects of cognitive demand on balance
  8. Self-report measures of balance activities
106
Q

To test limits of stability:

A
  • Functional Reach Test
    • FRT has been found to be predictive of falls among older adults
  • Also: Multi-Directional Reach Test (MDRT), an expansion of the FRT, examines the older adult’s limits of stability backward and laterally to the right and left, in addition to the forward direction
107
Q

Testing Anticipatory Postural Control

A
  • Portions of the dynamic gait index
  • telling the older adult a nudge is going to be applied in advance of the action and he or she needs to resist it
  • asking the individual to negotiate an obstacle course.
108
Q

Testing reactive postural control

A
  • Nudge test, by Tinetti
  • Postural Stress Test
109
Q

Testing Functiional Ballance Skills and Balance Measures

A
  • Timed and Get up and-Go tests are used to measure an individual’s functional dynamic balance

  • Berg Balance Scale (BBS)
  • balance portion of the Tinetti Performance-Oriented Mobility Assessment (POMA)
  • Fullerton Advanced Balance (FAB) scale
    • intended for use in higher-functioning older adults because the majority of items are considerably more challenging than the POMA or BBS
  • Balance Evaluation Systems Test (BESTest)

Q

Should single tests of mobility be used to identify fall risks in older adults?

A
  • No
  • clinicians who assess older adults for risk of falling should ideally do so in a comprehensive manner rather than relying on a single test of mobility and that the multifactorial nature of falls should be taken into account
