Post-stroke motor recovery suggests the existence of a period of heightened plasticity in which the survivors seem to be more responsive to treatment. This is the so-called ‘critical time-window’ for recovery. In short, a systematic review in 2002 found that on average, recovery reaches a plateau at 15 weeks for patients with severe hemiparesis and at 6.5 weeks for patients with mild hemiparesis.
This is one of the reasons that you may well have already heard from a number of sources that 3 months to 6 months to recover function is your limit, and after that, improvement is probably going to range from very difficult to impossible. The field of neurorehabilitation has generally accepted this time-window in the past and the hypothesis has also justified the general cessation of physical therapy at chronic stages.
But you must also appreciate that a gradient of significant possible responsiveness to treatment (and also responsiveness to neglect of rehab/retraining) that extends after 12 months post-stroke has been uncovered, which is VERY relevant for the majority of stroke patients.
Pay attention to the way the red line shows the possibility of improvement in body functions and activity after six months, as well as the possibility of decline.
The chart above, published in the Lancet in 2011 by experts in stroke (Professors Peter Langhorne in the UK, Julie Bernhardt in Australia and Gert Kwakkel in Holland), clearly shows this.
All research professionals in stroke want to locate optimal routes/combinations of interventions & therapies for you to improve. But as it stands right now, the optimal timing for rehabilitation and intensity of treatment remains unclear. Research scientists are currently trying to determine the best time after stroke for intensive motor training and others are investigating the effect of early and intensive therapy on upper extremity motor recovery.
The evidence is starting to show that physical therapy and self-training can have a significant impact on body structure and the function of the upper extremity at all periods post-stroke. So, if you can, please try to pay as little attention as you can to anyone making the point that your ‘time window’ has either fully closed or is about to fully close from now on and let’s crack straight on with working very hard (and with know-how of what to do/what not to do) at your recovery. Who knows what will happen? Make efforts – and locate someone to help. Even coaches need a coach. I do! I have a strength training partner who works in the neurorehabilitation field, who acts in that way for me and has done for around 20 years now.
Even if you’re unlucky and can’t find a therapist or trainer who is able to assist you, it’s about using self-help guides (like Had a Stroke, How What, from which this article is taken) to steer your recovery through the stroke maze. This is the reality. You just need to start. Plasticity will be kicked into high gear when your brain perceives new information as particularly important and when your training is frequently repeated. After a significant period of honest effort of pure ‘rehabby’ efforts, you’ll be transformed both physically and mentally.
To help with task-training, strength training and developing physical coping (not compensation) strategies, there are also so many adjuncts to community stroke rehab retraining these days – low tech to high tech – from AFO’s that can phase you on from rigid plastic orthotics, to upper limb de-weighting devices, simple and cost-effective devices like the Neurogripper (shown right, and available from ARNI), dynamic orthoses, upper and lower limb robots, virtual reality, FES, EMG biofeedback, telerehab and apps etc and there a number of well-evidenced clinical interventions too to target limitations from stroke, from targeted intensive therapies like CIMT, to pharmacological and even to surgical.
But here’s the thing. The day will come when you’ve found a combination of external adjuncts and retraining elements that works for you. If you haven’t or can’t, PLEASE consult a physiotherapist. And ‘phone up ARNI – we can and we will help to guide you.
I make my view about stroke rehab very clear, which is that if it’s ‘by rote’ and too ‘samey’ and doesn’t challenge you to work on the edges of your ability during your days, then the best way forward, to accompany retraining efforts is to consciously accompany your active recovery efforts with a physio or trainer with an into an actual hobby that is enjoyable and very productive. Or a couple of hobbies with different emphases. If you need to work this through with a health professional or family member or friend, then that’s just great – do is as part of on-going goal-setting/accomplishing…
The best results I’ve seen are when people start to do new hobbies which creatively challenge their own functional limitations. Producing artwork, music making, swimming, cooking, indoor shooting, model railway or Airfix kit constructing and photography are all examples which can be made to be highly rehabilitative if used to directly/knowingly/progressively to tackle motor limitations.
Many more examples of these are revealed in ‘Had a Stroke? Now What?‘, including the combination of ‘hobbies’ that I used to support my very successful upper limb rehabilitation
So, it will be time to get out there and do all sorts of things that are open to you as you seek to create (and get healthy) in the 21st century. And this will open up a whole new tranche of innovative new recovery possibilities. You’ll see. I can promise you that the ‘doing’ of a creative hobby or two which repetitively involves your more-affected limbs is the most efficient way to keep recovery and self-management efforts going over the long term. It’s the ‘no-rehab optimal rehab style’!

This platform includes a smartwatch app with tailored coaching to help people own their rehabilitation journey and inform their clinicians on their progress. The smartwatch app works like a step counter, it tracks minutes of arm activity through an algorithm developed for stroke survivors.
This will involve wearing wrist-based sensors and motion trackers during a 2 hour session at Imperial’s White City Campus to carry out tasks of daily activities such as using a knife and fork, reading a book and more.

Rehabilitation after stroke is a partnership between you and your ARNI instructor or therapist. You’ll know that regular practice of techniques and exercises is necessary to optimise progress after stroke, but during the times that your Instructor isn’t present, these may or may not be difficult to perform.
Currently there is no stroke specific measurement tool available to do this. This study aims to address this gap in stroke rehabilitation.

Tiredness is something we all experience in our everyday lives. But how about the sort of tiredness which seems to be unrelated to physical or mental exertion, and does not seem to be alleviated by rest? This is a real problem for many stroke survivors on top of the many other problems they may face – and is called ‘fatigue’.
The Effort Lab, led by
It takes no more than 45 minutes on an online combined quiz and questionnaire:
Strong evidence exists that physiotherapy improves the ability of people to move and be independent after suffering a stroke. But at six months after stroke, we know that many people remain unable to produce the movement needed for every-day activities such as answering a telephone. So, what can be done?
2. Second, to optimise a physiotherapist’s chances to advise/work on an optimal combination of rehab interventions for each individual after stroke, it would be ideal to find out what kinds of sleep patterns are most beneficial for them.
Ideally, more portable equipment should also be able to be accessed by therapists, which would cost less and is designed for use in small spaces. But such equipment would have to also be sensitive enough to provide meaningful feedback for therapists in a similar way to those used by the specialist labs. Such feedback could then be very useful for therapists and survivors to create optimal rehab plans together which would really enable the survivor to work on his/her edges of current ability.

A few lifestyle changes could reduce your risk.
In order to bring about functional change, neural pathways for desired activities need to strengthened. At a very basic level, this can be optimally achieved through repetitions (facilitated by ‘smart’ use of use of some augmentations and principles which one can ‘add’ to movements to optimise their performance over time, always trying to work ‘on the edge of your current ability. How do do this is explained in my ‘stroke rehab possibilities wheel diagram’ in
