Professor Miguel Nicolelis (2019) has published a free copy of his contributions to BMI (brain-machine interfaces) emphasizing his twenty years of work starting in 1999 and continuing through 2015.* Until 2003, Nicolelis had no competitors, but shortly thereafter Andersen et al. (2003), Schwartz et al. (2004) and Donoghue et al. (2006) joined the field, and tried to eclipse him and his associates [as described in Tehovnik, Waking up in Macaíba, 2017]; they, however, failed to achieve the eclipse, since the information transfer rate of their devices were typically below 1 bit per second at an average of about 0.2 bits/sec, much like what Nicolelis’ devices were transferring (Tehovnik and Chen 2015; Tehovnik et al. 2013). By comparison, the cochlear implant transfers 10 bits/sec (Tehovnik and Chen 2015) and therefore has been commercialized with over 700,000 registered implant recipients worldwide (NIH Statistics 2019).
BMI technology is still largely experimental. Willett, Shenoy et al. (2021) have developed a BMI for patients that transfers up to 5 bits/sec for spontaneously generated writing, but it is unclear whether this high rate is due to the residual movements (Tehovnik et al. 2013) of the hand contralateral to the BMI implant. To date, the most ambitious BMI utilizes a digital bridge between neocortex and the spinal cord below a partial transection to evoke a stepping response that still requires support of the body with crutches; but significantly the BMI portion of the implant in M1 enhances the information transfer rate by a mere 0.5 bits per second, since most of the walking (86% or 3.0 bits/sec of it) is induced by spinal cord stimulation in the absence of the cortical implant (Lorach et al. 2023). Accordingly, BMI falls short of the cochlear implant and thus BMI developers are years away from a marketable device. The pre-mature marketing by Nicolelis at the 2014 FEFA World Cup of his BMI technology (Tehovnik 2017b) should be a warning to Elon Musk (of Neuralink) that biology is not engineering, for if it were a BMI chip would now be in every brain on the planet. See figure that summarizes the information transfer rates for various devices including human language.
US health coverages exclude cognitive rehabilitation (CR) after stroke due to a lack of evidence of efficacy.
I am hoping to find a measure to track a patient's progress in treatment.
I'm looking for cognitive rehabilitation programs for free or pdf schedules. There is someone who could help me?
I am using COGNIPLUS program as a rehabilitation computerized tool but not sure how many session will be enough to expect cognitive enhancement. I set 24 1.5 h. sessions , twice a week. And I am not quite sure if I am going the right direction. Is anybody familiar with COGNIPLUS (SCHUHFRIED Co.)?
Hi everyone.
I try to find some simple method to measure body-posture. We know a lot of them, but they are either low objective (aspect-based methods) or very difficult and expensive (Formetric 4D). Some advice...?
I know about nice resarch from Australia (https://bmcmusculoskeletdisord.biomedcentral.com/articles/10.1186/1471-2474-9-113), but I miss some more informations and all my attempts to contact authors ended up failing.
Thanks in advance, Lenka
Microperimetry is an important diagnostic tool in patients with macular diseases and plays a role also in rehabilitation in relation to the PRL.
I am a psychomotor therapist and I am implementing cognitive remediation approaches in child psychiatry. I would like exchange with researchers and therapists about clinical practice and deep clinical know how in this area...
Is there someone interested in ?
Exoskeletons assist physical tasks by applying significant forces that actuate human joints. Users feel these forces as more or less comfortable depending on the design of the physical interfaces, e.g. wide contact surfaces and soft materials.
I would be happy to hear your experience on what factors affect user comfort the most, when going for larger and larger assistive forces.
My feeling is that at some point the discomfort caused by large forces overcomes the benefits of being physically assisted, resulting at best in users preferring not to wear the exoskeleton in the first place.
Maybe a comprehensive neuropsychological test battery like the NAB (Petermann, Jäncke & Waldmann, 2016) would be helpful in providing a broad cognitive profile!
Is there a validated german translation of the "vestibular disorder activities of daily living scale" (VADL)? Thank you
There is a social innovation model in India in the rehabilitation of the mentally ill through individual initiatives and community support. It is innovative due to the new relationship the community people involved in and the new ideas generated out of it. The researcher used grounded theory as methodology and if any international journals are interested in the original work please let me know.
A protocol for rehabilitation team.
I'm looking at putting together some training on this and am reviewing the literature before developing the content. I'm interested in how professionals approach boundaries between professional/personal, especially with consideration to individuals with cognitive impairments who may struggle to retain information about boundaries, and also when therapists take a role in social rehabilitation.
It would really help me!
AAT interventions are often used in mental health practice, yet there is little research on its use in improving social skills and memory in persons with ABI. I am looking to use this literature to build a strategy within traditional cognitive rehabilitation that would increase successful and long termpositive outcomes.
I am particularly interested in the standard of care for cognitive rehabilitiation in adults or children who have suffered a stroke.
I have the measure and the user manual but annot find the subscale or the total cut off scores for the measure. Does anyone have them? Or can you point me towards a paper that has published these? This is for research only, not for clinical screening.
I have read little about IADL performance observations in dementia (or other cognitive disorders) due to the limited evidence base, yet was wondering whether there is any more research done that I did not come across yet?
I am trying to understand the concept of FES. Since I'm not an expert in rehab research, is there any good link or maybe good review paper that I can read that clarifies the research direction of this FES? For those who are experts, is there any issue or gap that can be filled if I'm interested in getting involved in this area of research? Thanks.
In neuropsychological & neuro-rehabilitation there are times when we meet clients who profoundly disagree with our analysis (which I accept is only ever a hypothesis). Sometimes the nature of the disagreement might be about expected outcomes. For example "when will my hand start moving again?" might be met with a therapist's view - this is a profound paralysis explained by extent of lesion and it might not voluntarily move again - that contrasts with the patient's view "if I keep seeking opinions, keep striving, someone might be able to help restore the lost function"). There are times when it is very difficult to shift from this narrative that seems to head into persisting disagreement&disappointment, preventing adjustment & acceptance. Playing into this context is a marketplace of people with their latest gadget or therapy approach. IN my view, this can perpetuate distress. I think there are some interesting therapeutic implications but not aware of much literature on this (?). I'd be fascinated to know if this is of interest to others in this forum. What therapeutic strategies would you try?
Technical support of every day clinical practice in neurorehabilitation increases with each day. Rehabilitation robots, virtual environments, telerehabilitation, eye-trackers, brain computer interfaces, neuroprostheses, exoskeletons becomes useful and effective tools for members of multidisciplinary therapeutic teams (especially physiotherapists). Where is the place of engineers within it? Will be there possibility (or even necessity) to incorporate them into therapeutic teams in the future?
I am interested in assessment of social communication of children with autism, but I would like develop alternative assessment methods from questionnaires.
I´m looking for some new updates in the treatment of DOC in order to improve neurorehabilitation programms
