    Rehabilitation is concerned with lessening the impact of disabling conditions. These are particularly common in older people and considerable health gain can be achieved by successful rehabilitation. Hospital doctors and general practitioners should be aware of the core principles of rehabilitation, be able to recognise rehabilitation need in their patients, and have sufficient knowledge of their local rehabilitation services to trigger the referral process.

    In Britain, an estimated 4.3 million people over 60 are disabled—this represents 70% of all disabled people and 46% of all older people.1 Most (over 90%) of older disabled people live in their own homes, and most (over 80%) have only “mild” disability, but many have several types of disability. Disability of all severity grades is strongly related to age, reflecting the increasing prevalence of the common disabling conditions: stroke, arthritis, cardiorespiratory diseases, fractured neck of femur, and peripheral vascular disease.

    Rehabilitation is a complex set of processes usually involving several professional disciplines and aimed at improving the quality of life of older people facing daily living difficulties caused by chronic disease. The key purposes of rehabilitation can be summarised succinctly:

    • Realisation potential

    • Re-ablement

    • Resettlement

    • Role fulfilment

    • Readjustment.

    Rehabilitation “myths”

    The process of rehabilitation is not always well understood. The commonest incorrect assumption is that rehabilitation is time limited, with a clear end point, finishing when the patient leaves hospital. Many patients deteriorate through disease progression, inactivity, new illness, or after a fall, so regular review and reassessment is an important aspect of effective rehabilitation. Another common misunderstanding is that the patient is a passive recipient of a “treatment,” as though the therapist were giving them a medicine. Rehabilitation is a highly energetic process in which the patient struggles against his or her disability with guidance from a rehabilitation team. It is not a “quick fix” but requires considerable patience and perseverance. Other myths are that rehabilitation is done only by “therapists” and can be done only in hospital departments; that it is appropriate only for people with mobility problems; that it is too expensive; and that it doesn't work.

    Successful rehabilitation

    It is easy for the rehabilitation process to focus predominantly on physical functioning. However, successful rehabilitation requires a broader perspective—one which allows social and psychological problems to be identified and addressed.

    Figure3

    Holistic rehabilitation involves more than just physical function

    Other success factors for rehabilitation are long established:

    • A positive attitude and approach

    • Individual assessment of patient and caregiver

    • Involvement of patient and caregiver

    • Team working

    • Promotion of independence by: Special and general therapeutic techniques Optimising the environment

    Several easily adopted practical approaches, described below, facilitate these factors and promote more successful rehabilitation outcomes. It is important to realise that rehabilitation involves several overlapping techniques which can be usefully separated into “hard” and “soft.” Hard rehabilitation involves some form of “hands on” treatment by a range of rehabilitation staff. Soft rehabilitaion is more easily overlooked but is often greatly valued by the patient. It involves talking to, listening to, understanding, and counselling the patient. Some patients require only soft rehabilitation, but a special skill of rehabilitation is to optimise the balance between the two processes.

    Assessment

    The classification which has now been widely adopted as a framework to assess patients for rehabilitation is based on four levels: pathology, impairment, disability, and handicap.

    Pathology—abnormality of structure or function affecting an organ or organ system—for example, osteoarthritis, ischaemic heart disease.

    Impairment—any loss or abnormality of psychological, physiological, or anatomical structure or function—for example, joint pain, breathlessness, muscle weakness, visual impairment, deafness.

    Disability—any restriction or lack of ability to perform a task or activity—for example, walking, dressing, going up and down stairs, hearing.

    Handicap—the disadvantages for a particular individual resulting from an impairment or disability that limits or prevents fulfilment of a role which is normal for someone of that age, sex or culture—for example, reading a newspaper, going to shops or the pub, gardening, attending a football match, playing the piano.

    Doctors tend to be most familiar with uncovering pathologies and impairments (“the diagnosis”), but patients with chronic disease are often more concerned with the consequences of their disease (disability and handicap). Many common aspects of disability can be systematically detected by using the Barthel index (box). Handicap, the particular consequence of the impairments and disabilities to the individual, is best detected by asking open questions such as: “What would you like to be able to do that you cannot do now?” or “What is stopping you going outside?” (fear of falls, too many steps, etc) or “What do you find most frustrating?”

    The Barthel index is now widely used in care of older people and rehabilitation departments. It assesses the level of independence or dependence for 10 activities of daily living with a score range of 0 (dependent) to 20 (independent). It is quick and easy to use, has been carefully researched, and aids systematic assessment of disability; when repeated at intervals it can indicate the progress of rehabilitation. The main disadvantages of the Barthel index are that it can be insensitive to change (patients may improve or deteriorate without a change in score) and that it has a low “ceiIing” (patients may have a maximum score but still be restricted by inability to go out, cook, clean house, use the bus, etc). Despite these limitations, the Barthel index should be more widely used.

    Strengths and weaknesses

    Creating opportunities and maintaining a positive attitude is essential in rehabilitation. One simple technique is to consider a disability situation in terms of strengths and weaknesses. Consider a 77 year old man who has just suffered a hemiplegic stroke and lives with his wife. His strengths and weaknesses can be listed:

    View this table:

    When they are set out in this way, it is surprising how often the strengths predominate. They can then be used to address the weaknesses. For example, for this man, occupational therapy input for training in dressing (using the strengths of unsupported sitting balance and wife) and physiotherapy input to teach assisted transfers (using the strength of the wife as caregiver) would be a positive beginning to the rehabilitation process.

    Goal setting

    Explicit goal setting is a central task in the management of disabled elderly people. Goal setting should be informed by careful assessment of the patient and preceed all rehabilitation interventions. Successful goals are recognised as being:

    • Meaningful—appropriate to the problems and circumstances of the patient

    • Agreed—consult and negotiate with patient, caregivers, and rehabilitation team

    • Clearly communicated—write them down

    • Realistic—challenging but achievable: not everyone can do everything.

    A rehabilitation goal is not a vague statement (for example, “we will improve mobility”) or a vague action (“we will refer to a physiotherapy department”). A rehabilitation goal is a precise statement and should be constructed so that its achievement is unambiguous.

    Barriers to rehabilitation progress

    Some patients may not make the amount of progress that was anticipated. Common reasons which should be considered are:

    • Unidentified medical problems, such as anaemia, heart failure (fatigue syndrome), undiagnosed Parkinson's disease, undiagnosed hypothyroidism, or the side effects of drugs (especially postural hypotension)

    • Occult depression—depression is commonly associated with physical disease in older people but is easily overlooked, and can have important consequences for the patient, who may benefit considerably from treatment with antidepressants

    • Occult dementia—some patients will have well preserved social skills which mask loss of intellectual function; impairment of memory, concentration, perceptual skills, and apraxia are common in Alzheimer's disease and prevent full cooperation with rehabilitation techniques, many of which are complex learning tasks

    • Communication problems—check vision (and spectacles); check hearing (and hearing aid).

    Remember the caregivers

    Caregivers have been addressed in an article earlier in this series.2 Their contribution needs to be positively acknowledged by purposefully allocating time to understand their perspective and needs. “Knowledge is power”—information giving and contact with support groups are particularly valued. The caregiver may be depressed or anxious and need treatment, and routine discussion of respite care (day or night sitters, rotational care) is recommended.

    Arranging rehabilitation for older people

    The rehabilitation services are characterised nationally by wide variation in availability, type, scope, and content. Several agencies and several departments within these agencies are usually involved, so general practitioners and hospital doctors need to become familiar with their local arrangements. However, selection of patients for referral—and selection of an appropriate rehabilitation service—are practical issues for which guidance in general terms is important.

    SELECTION OF PATIENTS

    Older people with the following should be considered for referral:

    • Disability but cause uncertain

    • New impairment, disability, or handicap

    • Deterioration in existing impairment, disability, or handicap

    • Strain on caregiver identified

    • Barely coping: residential or nursing home care being considered

    • New referral to home care service.

    Considerations for inpatient and outpatient rehabilitation

    Inpatient rehabilitation

    • High dependency/high care needs (especially night time care)

    • Complex or multiple disability

    • Rapid response needed

    • Poor housing or unsuitable domestic circumstances

    • No community rehabilitation available Outpatient rehabilitation

    • Low or modest dependency

    • Less complex disability

    • Slower response acceptable

    • Appropriate housing and domestic circumstances

    SELECTION OF A REHABILITATION SERVICE

    Many older patients become disabled by an acute illness such as a major stroke, fractured neck of femur, or pneumonia and require emergency hospital admission for medical and rehabilitation care. For other patients, however, it may be less clear whether inpatient or outpatient rehabilitation is most appropriate. Discussion with a general physician or geriatrician, or a prior domiciliary assessment visit, may be helpful in such uncertain circumstances. Key aspects of the decision process are given in the box.

    Outpatient rehabilitation can be organised by referral to an outpatient therapy department, a geriatric day hospital, or a home or community rehabilitation team. In general, clearly defined single problems (difficulty walking, difficulty bathing, etc) can be attended to in outpatient therapy departments but more complex or poorly defined problems, such as “not coping” or falls, are often best managed in a geriatric day hospital. However, care is needed in the referral process as some aspects of impairment and disability are clearly visible (such as knee pain and restricted mobility) but other aspects (such as being unable to do kitchen work) may be hidden. A full disclosure of all important aspects of disability in older people is often best undertaken by a rehabilitation team. This is most usually available via the day hospital.

    Equipment and services commonly required by older people disabled by osteoarthritis

    View this table:

    It has been increasingly recognised that assessment and treatment of older people in their own home has advantages over departmental based assessments. Real daily life problems are more apparent; there is greater opportunity to involve the family; and there is greater opportunity to involve home care and community nursing staff. Some districts now provide separate home rehabilitation teams to achieve this, while in other districts the therapy team is based in the day hospital but much of the assessment and treatment takes place in the patient's home.

    COORDINATION OF REHABILITATION

    Coordination of effort between the members of a multidisciplinary rehabilitation team and between rehabilitation services is important but can be difficult to achieve. It should be easier in hospitals: elderly care wards, rehabilitation wards, stroke, and orthogeriatric units are structures which greatly facilitate team working and coordination between disciplines and agencies. It can be considerably more difficult outside the hospital as natural teams do not usually exist but need to be purposefully formed around individual patients. Consider the common situation of an elderly housebound woman disabled by osteoarthritis who wishes to remain in her terraced council house. A range of services and equipment is required, the access to which may defeat all but the most tenacious of rehabilitation staff. The box on the previous page provides an example.

    Rehabilitation research

    Although the research base for rehabilitation has expanded considerably, evidence for effectiveness remains patchy. There is evidence to support the general concepts of the rehabilitation process for older people, for stroke units and some evidence to support orthogeriatric units. Several randomised trials of domiciliary rehabilitation have been undertaken with encouragingly positive results.

    Findings of studies of rehabilitation in the home

    View this table:

    Perhaps the most surprising finding from the domiciliary rehabilitation studies is how little therapy input is required. Several of the studies used only two or three visits, yet the health gain for the patient was considerable, especially for interventions consisting of occupational therapy.
