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
