Rehabilitation in Older Adults
Rehabilitation in older adults is a goal-directed, multidisciplinary process aimed at restoring function and independence after illness or injury, underpinned by comprehensive geriatric assessment.
Key Facts
- Rehabilitation is a goal-directed process enabling a person to reach their optimal physical, psychological, and social functioning
- MDT approach is essential: geriatrician, physiotherapist, occupational therapist, SALT, dietitian, social worker, psychologist, nursing
- Comprehensive Geriatric Assessment (CGA) underpins all rehabilitation programmes for older adults
- Early mobilisation (within 24 hours of admission) reduces deconditioning, delirium, VTE, pressure ulcers, and length of stay
- Goal-setting should be patient-centred, SMART (Specific, Measurable, Achievable, Relevant, Time-bound), and regularly reviewed
- Common rehabilitation settings: acute hospital, community rehabilitation unit, intermediate care, home-based rehabilitation
- Functional independence is the primary outcome measure; tools include Barthel Index (0-20/100) and Functional Independence Measure (FIM)
- Deconditioning in hospital: older adults lose 5% of muscle strength per day of bed rest; 10 days of bed rest = 10 years of muscle ageing
Overview
Key Facts
Rehabilitation is a core function of geriatric medicine. It requires active patient participation, realistic goal-setting, and coordinated multidisciplinary input.
Epidemiology
- Approximately 30-50% of hospitalised older adults experience functional decline during admission
- 10 days of bed rest in a healthy older adult leads to 14% loss of aerobic capacity and 10% loss of muscle strength
- Intermediate care and rehabilitation services handle >500,000 episodes per year in England
Aetiology
Rehabilitation is needed after:
- Acute illness (pneumonia, sepsis, AKI)
- Surgical procedures (hip fracture, joint replacement, cardiac surgery)
- Neurological events (stroke, head injury)
- Prolonged immobility or deconditioning
- Falls and fractures
- Amputation
Pathophysiology
- Deconditioning syndrome: bed rest → sarcopenia, reduced cardiovascular fitness, joint contractures, pressure ulcers, constipation, postural hypotension, depression, cognitive decline
- Neuroplasticity: the brain can reorganise after injury (basis for stroke rehabilitation)
- Motor learning: repetitive task-specific practice improves function
Clinical Presentation
Assessment
- Pre-morbid function (what could the patient do 2 weeks before admission?)
- Current functional ability (mobility, transfers, washing, dressing, toileting, feeding)
- Cognition (capacity to participate, learning ability)
- Mood (depression significantly impairs rehabilitation participation)
- Social circumstances (home setup, carers, support)
- Patient's own goals and priorities
Rehabilitation Potential
- Motivation and engagement
- Pre-morbid function
- Cognitive ability to learn and participate
- Medical stability
- Adequate nutrition
- Realistic goals achievable within timeframe
Red Flags
- Failure to progress despite appropriate rehabilitation
- New medical deterioration during rehabilitation
- Persistent delirium impeding participation
- Safeguarding concerns (e.g. unsafe home environment)
- Worsening mood/psychological distress
Differential Diagnosis
| Barrier to Rehabilitation | Key Features | Intervention |
|---|---|---|
| Delirium | Fluctuating attention, acute onset | Treat underlying cause |
| Depression | Low mood, amotivation, apathy | Antidepressant, psychology |
| Pain | Limiting movement and participation | Optimise analgesia |
| Cognitive impairment | Poor carryover, inability to learn | Adapted approach, repetition |
| Medical instability | Recurrent infection, cardiac events | Medical optimisation |
Diagnosis / Investigation
Bedside
- Barthel Index: ADL assessment (0-100; higher = more independent)
- Functional Independence Measure (FIM): 18 items, motor + cognitive (18-126)
- Timed Up and Go (TUG): functional mobility
- Grip strength: dynamometry
- Cognitive assessment: MoCA, ACE-III
- Mood screening: GDS-15, PHQ-9
- MUST: nutritional assessment
- Home assessment (OT): evaluate equipment needs, safety
Bloods
- FBC, U&Es, vitamin D, albumin, TFTs, B12/folate (optimise medical status)
Imaging
- As indicated by medical conditions
Special Tests
- COPM (Canadian Occupational Performance Measure): patient-centred goal-setting
- EQ-5D: quality of life measure
- Therapy assessment: detailed physiotherapy and OT assessments
Management
Non-pharmacological
- Early mobilisation: within 24 hours of admission (unless contraindicated)
- Physiotherapy: strength training, balance, gait re-education, endurance
- Occupational therapy: ADL practice, home assessment, equipment provision, cognitive rehabilitation
- SALT: swallowing rehabilitation, communication therapy
- Dietitian: nutritional optimisation (protein 1.0-1.2 g/kg/day)
- Psychology: managing adjustment, depression, anxiety, motivation
- Social work: care packages, housing, benefits, carer support
- Goal-setting: SMART goals, reviewed weekly at MDT meeting
- Discharge planning: starts from day 1; community rehabilitation, intermediate care, home adaptations
Pharmacological
- Optimise medical conditions: pain management, blood pressure, diabetes, heart failure
- Vitamin D supplementation: 800-1,000 IU daily
- Treat depression: SSRIs if indicated (may improve rehabilitation engagement)
- Medication review: stop medications causing sedation, postural hypotension, or cognitive impairment
Surgical/Interventional
- Joint replacement rehabilitation protocols
- Hip fracture rehabilitation (BPT standards: physio from day 1)
- Post-amputation rehabilitation and prosthetic fitting
Referral Criteria
- All older adults with functional decline: rehabilitation assessment
- Complex needs: community rehabilitation or intermediate care
- Stroke rehabilitation: specialist stroke rehabilitation unit (NICE NG236)
- Unable to return home: social services, intermediate care, residential assessment
Prognosis
- Early mobilisation reduces hospital LOS by 1-2 days and reduces complications
- Intermediate care rehabilitation: 60-70% of patients return home
- Hip fracture rehabilitation: 50% regain pre-fracture mobility
- Stroke rehabilitation: greatest recovery in first 3 months; continued improvement up to 12 months
- Deconditioning is largely reversible with appropriate exercise
- Factors predicting good outcome: good pre-morbid function, motivation, intact cognition, social support
