What traumatic brain injury means
A traumatic brain injury (TBI) happens when an external force — a fall, a road traffic collision, or a blow to the head — disrupts normal brain function. Doctors classify severity using the Glasgow Coma Scale (GCS) together with how long a person was unconscious and how long their memory was affected afterwards (post-traumatic amnesia). Mild TBI, commonly known as concussion (GCS 14–15), typically involves loss of consciousness under 30 minutes and amnesia lasting less than 24 hours. Moderate (GCS 9–12) and severe TBI (GCS 3–8) involve longer periods of unconsciousness, amnesia of 24 hours or more, and often visible changes on brain imaging. This spectrum matters because recovery needs vary enormously — from a concussion that settles within weeks to a severe injury requiring years of coordinated, multidisciplinary rehabilitation.
TBI is far more common than many people realise. Globally in 2021, there were an estimated 20.84 million new cases and close to 38 million people living with the effects of a TBI, with falls as the leading cause, followed by road traffic injuries and interpersonal violence (Global Burden of Disease Study 2021). Low- and middle-income countries carry a disproportionate share of this global burden, with roughly three times more total TBI cases than high-income countries (NCBI Bookshelf).
Locally, the picture has shifted with an ageing population. In a Singapore hospital cohort, 58% of TBI patients were now aged over 60, up from 24.6% a decade earlier, and unwitnessed falls caused 70.7% of injuries in patients aged 65 and above, compared with motor vehicle accidents causing 41.8% of injuries in the 19–40 age group (Frontiers in Surgery). This means many families in Singapore are now navigating TBI recovery in an older relative rather than, as was once more typical, a younger adult after a road accident — and home-based rehabilitation is often a natural fit for this group.
Balance and mobility problems are among the most common and functionally limiting after-effects of TBI, affecting an estimated 39–62% of people who experience one (ScienceDirect). These difficulties — along with dizziness, weakness, fatigue, and reduced confidence — are exactly what a structured physiotherapy programme is designed to address.
How home physiotherapy helps
Physiotherapy is a core part of standard TBI rehabilitation, and the evidence base, while still developing, is encouraging. A systematic review of exercise-based interventions found generally positive effects on fitness, gait, and balance in adults living with the longer-term effects of TBI, although the authors noted that the underlying studies varied in quality (Brain Injury, PubMed). It's worth being upfront about the state of the science: a broad overview of six Cochrane reviews covering 42 studies and nearly 4,000 TBI participants found that certainty of evidence for specific rehabilitation interventions was generally low to very low, with only 3% of comparisons rated as high quality (Cochrane overview, PMC). This doesn't mean rehabilitation doesn't work — it remains standard of care worldwide — but it does mean claims should stay grounded, and progress is tracked individually rather than promised in advance.
Some specific approaches have stronger supporting data. A randomised controlled trial in adolescents with concussion found that those given a daily programme of sub-symptom-threshold aerobic exercise recovered significantly faster, with a 48% reduced risk of developing persistent post-concussive symptoms, compared with a stretching-only routine (Leddy et al., The Lancet Child & Adolescent Health). Separately, a randomised trial of high-intensity gait training after TBI found significant improvements in walking ability, supporting the use of structured, progressively challenging walking practice rather than passive or low-intensity approaches (Neurotrauma Reports).
For dizziness after mild TBI, a 2023 systematic review and meta-analysis found vestibular rehabilitation therapy produced meaningful short-term improvements in perceived dizziness and post-concussion symptoms, though these benefits had diminished by the two-month mark, objective balance measures didn't improve significantly, and overall evidence certainty was rated low (PubMed). This is a useful reminder that vestibular work is often most effective as one part of an individualised plan rather than a stand-alone fix. Interestingly, passive approaches don't fare as well: a Cochrane review of stretching in neurological conditions, including TBI, found no clinically meaningful effect on joint mobility, quality of life, pain, spasticity, or participation, which is why home programmes here emphasise active, task-specific exercise over passive stretching alone (Physiopedia summary).
Home-based delivery adds practical value on top of this evidence: therapy happens in the environment where balance, walking, and daily tasks actually need to work — around real furniture, real stairs, and real routines — which supports carryover into everyday life.
What a home visit looks like
A first home visit typically starts with a conversation and a functional assessment: how the person is walking, transferring, balancing, and managing daily activities, alongside a review of medical history, hospital discharge notes, and any red-flag symptoms that need monitoring. From there, the physiotherapist sets realistic short- and longer-term goals together with the person and their family, taking into account the home layout, available support, and what matters most to daily life — whether that's climbing the stairs to a bedroom, walking to the kitchen safely, or regaining the confidence to be alone at home for short periods.
Each subsequent session builds on this with hands-on practice, progressively harder exercises, and practical safety advice for the home environment (footwear, lighting, clutter, rails). Families are usually shown how to support practice between visits, since consistency between sessions matters more than any single visit. Progress is reviewed regularly and the plan adjusted — TBI rehabilitation is rarely a straight line, and pacing is adjusted around fatigue, mood, and medical appointments as needed.
Typical recovery timeline
Recovery trajectories differ substantially by severity, and setting realistic expectations early helps families plan. For mild TBI (concussion), symptoms typically resolve within 10 days to 3 months for most people. It's worth knowing that a meaningful minority continue to report some symptoms a year after injury — estimates in the research literature vary widely, from roughly 10–15% up to 45%, depending on the population studied and how symptoms are measured — which is why ongoing monitoring matters even when an injury is labelled "mild."
Moderate-to-severe TBI follows a longer arc. The first 3 to 6 months after injury usually bring the fastest functional gains, a period of accelerated recovery generally continues from around 3 to 12 months, and meaningful improvement can continue for up to two years or longer with sustained rehabilitation. Among patients who were in a coma at hospital discharge, the majority go on to regain consciousness during inpatient rehabilitation, and a substantial proportion go on to regain full or semi-functional independence, with nearly half of people with severe TBI achieving independent function by 12 months post-injury. Recovery is rarely a straight line — plateaus and setbacks are a normal part of the process, not a sign that rehabilitation has stopped working.
Home-based physiotherapy is typically most valuable in the subacute-to-chronic phases, once medical stability has been confirmed by the treating medical team, and works best as a continuation of gains already made in hospital or outpatient rehabilitation rather than a replacement for acute medical care.
Exercises and approaches used at home
A home programme is individualised, but commonly draws on:
- Gait and locomotor training — progressive, task-specific walking practice, including higher-intensity treadmill or overground gait work, to rebuild walking speed, endurance, and safety.
- Balance and postural control retraining — graded exercises through sitting, standing, and step-stance positions to improve weight transfer and reduce fall risk.
- Vestibular rehabilitation — habituation, gaze-stabilization, and balance exercises for dizziness and disequilibrium after head injury.
- Strength and resistance training — individualised strengthening, including functional resistance work, adapted for weakness, spasticity, or postural control challenges.
- Cardiovascular/aerobic conditioning — graded aerobic exercise kept below the symptom threshold, to rebuild fitness and, in concussion, support faster symptom recovery.
- Functional and community-reintegration training — higher-level motor and safety-awareness tasks that support a return to daily home life and, over time, the wider community.
A note on safety
Home physiotherapy is appropriate only once a person is medically stable and has been cleared by their treating doctor or neurosurgical team. It is not appropriate for an acute or undiagnosed head injury, suspected bleeding in the brain, uncontrolled seizures, or any new or worsening neurological symptom — these need urgent medical evaluation first. Seek emergency care immediately if someone with a head injury develops a worsening or severe headache not relieved by painkillers, repeated vomiting, increasing confusion or unusual behaviour, loss of consciousness for more than 30 seconds, seizures, new weakness, numbness or tingling in an arm or leg, slurred speech or vision changes, or clear fluid or blood leaking from the ears or nose.
Taking the next step
Recovering from a traumatic brain injury takes time, patience, and consistent effort — and progress often shows up gradually rather than all at once. The encouraging part is that structured, active rehabilitation, delivered consistently and adapted to the person in front of us, is genuinely able to support meaningful gains in walking, balance, strength, and everyday independence. If someone in your family is at the stage where their medical team has confirmed they're ready for rehabilitation, a home visit can be a practical way to begin — in the surroundings where those skills will actually be used every day. Reach out to arrange an assessment or ask any questions about whether home physiotherapy is the right fit right now.
