Introduction
Physical therapy plays a vital role in supporting individuals with dementia by promoting mobility, safety, and overall physical well‑being across all stages of the condition. As dementia progresses, changes in balance, strength, gait, coordination, and motor planning can significantly increase the risk of falls and functional decline. Physical therapists help address these challenges through targeted exercise, balance and gait training, fall‑prevention strategies, and caregiver education. By maintaining physical function and supporting safe participation in daily activities, physical therapy enhances quality of life, reduces secondary health complications, and helps individuals with dementia remain as independent and active as possible.
Strategies for Success
Mobility impairment in older adults can result from impairment in multiple physiological and neurological domains, each contributing to further age-related decline in functionality and vitality. Impairments in cognition and mobility often go hand-in-hand, and impairment in one often accompanies impairment in the other. Compared to cognitively intact individuals, older adults with cognitive impairment tend to perform more poorly on mobility tests and report higher levels of disability. There is also evidence to suggest that a decline in cognition is associated with a decline in mobility, regardless of whether the physical task requires a great cognitive input or not. Consider referral to physical therapy if any of the following are present:
Decline in Mobility/Gait
Refer when there is:
New or worsening difficulty walking
Shuffling gait, slowed gait, or reduced stride length
Decreased walking endurance or increased fatigue
Difficulty navigating indoor or outdoor environments
Why: Dementia frequently causes motor planning deficits and mobility decline, which PT can slow and improve (Alzheimer’s Association; APTA Geriatrics).
Recurrent Falls or High Fall Risk
PT referral is indicated for:
One or more falls within the past year
Near‑falls or loss of balance
Fear of falling
Postural instability
Poor safety awareness
Why: People with dementia have a 2–3× increased fall risk (CDC; National Institute on Aging). PT reduces fall rates through strength, balance, and environmental strategies.
Functional Decline in Activities of Daily Living (ADLs)
Signs include:
Difficulty transferring (bed, chair, toilet)
Trouble getting up from sitting
Reduced ability to climb stairs
Trouble standing without support
Why: PT can maintain independence with task‑specific training and caregiver education.
Physical Deconditioning or Sedentary Behavior
Refer when you observe:
Spending most of the day sitting or in bed
Weakness due to inactivity
Poor endurance or rapid fatigue
Why: PT supports exercise planning, safe strengthening, and activity pacing.
Pain That Limits Movement
Especially:
Arthritis, back pain, neuropathy
Pain causing decline in mobility or function
Pain expressed through behavior (agitation, guarding) when verbal communication is limited
Why: PT can reduce pain and improve mobility, often reducing behavioral symptoms.
Difficulty With Balance or Coordination
Indicators include:
Unsteady stance
Difficulty turning
Trouble with dual‑tasking (walking + talking)
Inability to step over obstacles
Why: Dementia alters motor planning; PT retrains balance and safe movement patterns.
Behavioral or Psychological Symptoms Linked to Physical Causes
Such as:
Agitation related to discomfort, immobility, or restlessness
Wandering that increases fall risk
Resistance to care due to pain during movement
Why: PT can help identify triggers, optimize comfort, and guide caregivers.
Postural Changes
Including:
Forward-flexed posture
Kyphosis
Loss of trunk stability
Why: Postural changes increase fall and aspiration risk; PT can provide targeted strengthening.
Difficulty With Motor Planning (Apraxia)
When dementia leads to:
Difficulty initiating movement
Difficulty sequencing steps in a task (e.g., standing up, walking)
Why: PT uses cueing, repetition, and compensatory movement strategies.
Need for Assistive Device Evaluation
Refer when a patient may need:
Cane or walker fitting
Training in safe use
Recommendations on wheelchairs or seating systems
Why: Improper devices can increase fall risk, especially in cognitive impairment.
Caregiver Burden Related to Mobility or Transfers
Examples:
Caregiver difficulty managing transfers
Unsafe home setup
Risk of caregiver injury
Why: PT provides training, safe‑handling techniques, and home‑environment recommendations.
