Before a stroke patient is discharged, many family members see themselves as a plain "helper", doing their best to support and to do everything. From the angle of evidence-based medicine, the more accurate position is that the carer is a member of the rehabilitation team. The American Heart Association guideline on adult stroke rehabilitation states clearly that rehabilitation needs team coordination, which necessarily covers the patient's support system (that is, family members and carers), and recommends regular assessment of the patient's fall risk, mobility, daily living and mood (Winstein et al., 2016).
To really protect a family, blind endurance is often not the answer. What counts is preparedness, a safe home and suitable equipment. A one-year study following 222 stroke patient and carer pairs found that when carers had higher "caregiver preparedness", it significantly buffered the negative effect of depression on quality of lifeand protected both patient and carer (Pucciarelli et al., 2022). With this at its core, this article goes from home modification to prevent falls, through the choice and use of assistive devices and holding and transfer techniques, to the carer's own physical and mental adjustment and support, and sets out an evidence-based home care guide. It also says honestly which practices have strong scientific evidence and which are "reasonable but unproven".
Part 1: Home modification to prevent falls
The aim of this part is to create a living environment for the patient that both prevents falls and has no barriers. Among the accidental injuries common in stroke patients, falls are not only the most frequent but also the best evidenced as preventable, and this is the part of the whole guide with the most solid medical evidence. According to high-certainty Cochrane evidence (22 studies and 8,463 community-dwelling older people), a home hazard assessment and modification for people at high risk of fallingreduces fall incidents by about 38% (about 26% overall). However, when rolled out to an unselected low-risk population, no significant benefit was found (Clemson et al., 2023). In other words, for high-risk cases such as those who are "unsteady after a stroke", investing time and resources in home modification is definitely well worth the effort.
Fall prevention in the bathroom and toilet
The bathroom is the place in the home with the highest fall risk and needs special care.
Why do accidents happen most easily in the bathroom? Because the bathroom floor is easily wet and slippery, the space is narrow, one has to sit down and stand up when going to the toilet or showering, and the lighting is often not bright enough. Together these make the bathroom a high-risk place for falls in the home.
Non-slip measures
- Keep the floor dry: wipe the floor dry straight after bathing
- Use non-slip mats: lay non-slip mats in the bath and on the bathroom floor
- Anti-slip treatment: a professional anti-slip treatment for the floor tiles can be considered
Fitting grab bars
- Beside the toilet: L-shaped or vertical grab bars, to help with sitting and standing
- In the shower area: horizontal and vertical grab bars to support standing
- Fixed into the wall: they must be drilled into the wall and not just the suction type
Bathing equipment
- Shower chair: lets the patient sit while washing and lowers the risk of slipping
- Handheld shower: convenient to use when seated
- Bath transfer board: a transfer board can be added if a bathtub has to be used
Bedroom and living room
Make sure the spaces used every day are safe and unobstructed.
Clear clutter from walkways and keep routes open
- Remove rugs: the edges of rugs are easy to trip on
- Tidy clutter: clear everything from the floor
- Fix cables: run cables along the wall or hide them in trunking
- Width of walkways: at least enough for a walking aid or wheelchair to pass (at least 90 cm is suggested)
Adjust the height of the bed so the patient can sit down and stand up easily
- Ideal height: the knees at 90 degrees when sitting
- How to measure: the bed surface height equals the knee height
- How to adjust: use a mattress raiser or change the bed frame
- Stability: make sure the bed does not slide (too low is hard to get up from, too high is unsafe)
Suggestions for home lighting: make sure the route to the toilet at night is bright enough. Motion-sensor night lights that come on when someone walks past can be fitted. There should be a light switch at the bedside within easy reach, and the light should be soft and not too glaring.
The doorway and corridor
These are the key places for getting in and out of the front door and moving around inside.
Dealing with thresholds
- Remove the threshold or change to a lower one
- Add a ramp plate to help cross the difference in height
- Make sure the wheelchair can go in and out smoothly
- Stick a bright coloured sticker on the threshold
Corridor handrails
- Handrails are advised for longer corridors
- The handrail should be at about the same height as the hip joint
- The ends of the handrail should curve into the wall, to avoid catching a sleeve
- Make sure the handrail is fitted firmly and does not wobble
Home fall prevention modification needs professional assessment and follow-up, and cannot be done by buying everything on a checklist alone: the study by Clemson et al. (2023) shows that effective fall prevention is not a matter of going through a checklist and fitting handrails and non-slip mats yourself. An occupational therapist or physiotherapist must first assess the individual patient's risk, then design a plan around the patient's activity habits, and give follow-up guidance on installation and in actual use. If a generic checklist alone is used to modify the home, the effect is greatly reduced. It is therefore advisable to arrange a professional home assessment before the patient is discharged.
Part 2: Choosing and using assistive devices
The aim of this part is "a workman must sharpen his tools first". Choosing suitable assistive devices not only raises the patient's independence but is also the key to truly easing the physical load on carers, backed by evidence. This point must be stressed: research shows that lowering the risk of carers straining their backs depends not on using more strength or a more "correct" posture to lift and hold, but on actually using assistive devices such as transfer belts and hoists (see Part 3 for the detailed evidence).
Mobility aids
Choose suitable walking aids according to the patient's mobility.
How to choose a wheelchair
- Large rear wheels (self-propelled): the patient can push it alone
- Small wheels (attendant-propelled): needs someone else to push
- High-back wheelchair: suits people with poorer head and neck control
- Lightweight folding: easy to carry when going out
- Buying advice: the model should be chosen after assessment by a therapist
How to choose a walking aid
- Quad cane: gives more support, suits people with poorer balance
- Single-point stick: suits people with better balance who need light support
- Walking frame (walker): gives the most support, suits early practice
- Wheeled walker: easy to move, but less stable
- Note: the height of the stick should be adjusted to wrist height
Daily living aids
Essential tools that make daily personal care easier.
Hospital bed
- Adjustable height: makes transfers easier and reduces bending for the carer
- Raising the head of the bed: raising it during meals helps prevent aspiration pneumonia
- Bed rails: prevent falling out when turning over
Commode chair
- Used at the bedside: reduces the fall risk of going to the toilet at night
- Wheeled commode: can be pushed straight into the bathroom
- Armrest design: helps with sitting down, standing up and keeping balance
Transfer belt
- The key to saving effort: fastened around the patient's waist to give a place to hold
- Safer: steadier and safer than pulling on clothes
- Protects the back: lowers the risk of back injury to the carer
How to use a transfer belt:first fasten the transfer belt firmly around the patient's waist (about navel height), and then the carer holds the handles on both sides of the belt with both hands. This lets the carer guide and support the patient more steadily when moving the patient from bed to chair or changing position, and greatly reduces the risk of hurting the patient by pulling on clothes or arms.
Making good use of assistive devices protects the back better than lifting technique alone: a Cochrane systematic review covering 9 randomised controlled trials (RCTs) and more than 20,000 workers found no evidence that teaching manual lifting technique alone can prevent back pain. What really reduces the load on the back is actually using transfer or lifting equipment (Verbeek et al., 2012). A transfer belt should therefore be prepared at home first, and if the patient cannot bear weight at all, a hoist should be considered, and never lift by strength alone.
Part 3: The carer's holding techniques and physical and mental adjustment
The aim of this part is clear: before caring for the patient, the carer must first protect themselves, especially the lower back, which is the easiest to strain.
Correct posture for holding and transfers (body mechanics)
The body mechanics principles below are reasonable and worthwhile everyday habits, but it must also be said plainly that current medical evidence shows that knowing the "correct technique" alone has not been shown to prevent back injury(Verbeek et al., 2012). The real key to protecting the back is, as above, using a transfer belt, using a hoist when needed, and arranging for two people to help together when caring for a patient with severe paralysis. Please treat the following rules as good habits that go with using equipment, and not as an absolute guarantee that "you will never strain your back once you have learned them".
Four points to protect the back: first, stay close to the patient, keeping the body as near as possible to the patient, so that lifting takes less effort. Second, keep the feet apart, with one foot in front of the other or side by side, for a steadier base. Third, bend the knees and not the waist, bending the knees when squatting and keeping the back straight. Fourth, use the strength of the legs, standing up by the force of the thighs and never pulling hard with the lower back.
Demonstration of safe transfer steps
- Before starting, explain clearly to the patient what movement is about to be done
- Make sure both of the patient's feet are flat and firmly on the floor
- Fasten the transfer belt on the patient and hold the handles firmly with both hands
- The carer slightly bends both knees and keeps the back straight
- Count "1, 2, 3" and use effort together
- Use the strength of the thighs to carry the body through the transfer
Common mistakes in lifting and holding
- Bending over and pulling hard: puts great pressure on the lumbar spine
- Standing too far away: increases the lever arm and takes more effort
- Pulling on the arm: may injure the patient's shoulder
- Standing on one leg: an unstable base that easily loses balance
- Sudden effort: there should be a warning and movements should be in step
- Doing it alone: patients with severe disability need two people to help
Steps for transferring from bed to wheelchair
- 1PreparationPush the wheelchair close to the bed, lock the brakes and fold up the footplates.
- 2Sitting upHelp the patient to sit at the edge of the bed, making sure both feet are firmly on the floor.
- 3Standing upHold the transfer belt firmly and, after counting 1-2-3, stand up together.
- 4Turn and sitTurn slowly in small steps, line up with the wheelchair and only then sit down slowly.
The carer's stress, burnout and support services
Only by looking after oneself first can a carer look after family in the long term. A carer's stress is not simply a personal emotional matter. A scientific statement from the American Heart Association notes that excessive stress on carers is one of the main reasons stroke survivors end up going into residential care (Bakas et al., 2014). In other words, giving carers support is itself a key part of helping the patient to keep recovering at home.
Preventing burnout: caring for a patient day after day can easily leave a person drained in body and mind. Taking a break from time to time is not selfish. Carers need enough room to rest to be able to go further and keep caring for their family.
Common sources of stress for carers
- Not enough sleep and feeling tired all the time
- Seeing friends much less and feeling isolated and unsupported
- Greater financial costs and burden at home
- Often worrying about the patient's rehabilitation progress and feeling anxious
- Disagreeing with other family members about care arrangements
- Having no rest or private time of one's own at all
Self-care suggestions
- Ask for help: let other family members share the load
- Respite services: use day care or short-stay respite services
- Keep up social contact: stay in touch with friends
- Exercise to relax: even if only for 15 minutes
- Join a mutual support group: talk with others in the same situation
- Professional support: seek counselling when needed
Preparing early helps ease the stress of caring:research shows that the better prepared a carer is for the caring work, and the earlier they build up confidence, the smaller the effect of depression on quality of life, which works for both the patient and the carer (Pucciarelli et al., 2022). So rather than waiting until the patient is home to take things as they come, it is better to learn transfer techniques, medicine feeding points, fall prevention measures and ways of adjusting emotionally before discharge. This is exactly what "the carer is also a member of the rehabilitation team" means.
Does carer training help? An honest look at the evidence
It is often said that "carer training helps ease the burden", but the related medical evidence is in fact mixed and should not be overstated. The earliest positive result came from a single-centre randomised controlled trial (covering 300 stroke patient and carer pairs). While patients were in rehabilitation, the study gave family members structured care skills training, and carers were found to have a lower burden score (32 against 41), less anxiety and depression, and lower overall care costs. The patients' mortality, rate of admission to residential care and degree of disability, however, were not affected (Kalra et al., 2004).
But when researchers tested the same training course again in a large pragmatic study, the positive effect could not be reproduced. In the TRACS cluster randomised controlled trial (covering 36 stroke units), neither the patients' physical function (Nottingham Extended Activities of Daily Living score 27.4 against 27.6) nor the carer burden (45.5 against 45.0) showed a significant difference between the two groups (Forster et al., 2013). Several pooled analyses since have likewise found the overall effect not significant (Jammal et al., 2024; Legg et al., 2011).
The honest conclusion: carer training is not a cure-all that has been "proven to ease burden", but nor is it worthless. Taking the current evidence together, the most promising approach is an educational intervention that is structured, delivered over several sessions (about 5–9), tailored to individual needs, and combines problem-solving skills, stress management and practical care operations, ideally starting before the patient is discharged (Bakas et al., 2014; Legg et al., 2011; Jammal et al., 2024). By contrast, one-off talks or handing out a generic leaflet alone have the most limited effect.
Support resources for carers in Hong Kong
Making use of formal community support means not having to go it alone on the caring road.
Carer resources in Hong Kong: you can contact the Social Welfare Department (for enquiries about day care for older people and respite services), ask a hospital medical social worker (MSW) for help (with applying for various community resources and financial assistance), browse the Hospital Authority's community resources page of 智友站 (Smart Patient) (for practical information on day care for older people and community rehabilitation), refer to the WE RISE (風起航) programme of the Sau Po Centre on Ageing at the University of Hong Kong (guidance for stroke families on discharge preparation, home modification, caring skills, respite arrangements and emotional support), and use the carer support services provided by the Hong Kong Society for Rehabilitation (復康會) and the Hong Kong Society for the Aged (耆康會).
Common warning signs of carer burnout
Watch in daily life for whether any of the following signs appear, and seek support early.
- Often feeling very tired, and not regaining energy even after sleep and rest
- Weakened resistance and falling ill easily
- Problems with sleep, such as insomnia or wanting to sleep all day
- Becoming short-tempered and losing temper easily over small things
- Often feeling hopeless, helpless or guilty
- Having no interest at all in things once enjoyed
- Ignoring one's own health needs
- Slowly drawing away from friends and family
- Relying on alcohol or medicines to relieve stress
Please remember: if you notice several of the above at the same time, ask for help at once. The carer's own physical and mental health is just as important, and the whole burden must not be carried alone. Try talking frankly with family at home, share the caring work, and make good use of the community's support services.
