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.

Answer
The amount of information current-day BMI systems transfer varies depending on the type of BMI and the specific task being performed. Here's a breakdown:
Information transfer rate (bits/second):
  • EEG-based BMIs (non-invasive): These BMIs measure electrical activity from the scalp and generally have lower information transfer rates, ranging from 0.25 to 0.5 bits/second. This is enough for basic control tasks like cursor movement or simple word selection, but not for complex actions.
  • Invasive BMIs: These BMIs use electrodes implanted directly in the brain, providing access to more detailed neural signals. Information transfer rates can be higher, reaching up to 40 bits/second for simple tasks like motor control. However, this is still significantly slower than natural human communication rates, which can reach 40-100 bits/second for speech and even higher for complex forms of communication like writing.
Factors affecting information transfer rate:
  • Type of brain activity: Different brain areas and signals carry different amounts of information. Motor cortex activity used for cursor control is easier to decode than complex cognitive processes like thoughts or emotions.
  • Electrode technology: The number and placement of electrodes influence how much neural activity is captured. More electrodes and better placement can lead to higher information transfer rates.
  • Signal processing algorithms: Algorithms used to interpret and decode brain signals play a crucial role in extracting information. Advancements in machine learning and artificial intelligence are improving decoding accuracy and information transfer rates.
Current limitations:
  • Low information transfer rates: Compared to natural communication, current BMIs are still relatively slow and limited in the complexity of information they can transfer.
  • Accuracy and reliability: Decoding brain signals can be challenging, leading to errors and inconsistencies in control.
  • Ethical considerations: Invasive BMIs raise ethical concerns about privacy, security, and potential misuse of brain data.
Despite these challenges, BMI research is rapidly advancing, and information transfer rates are expected to improve significantly in the future. This could revolutionize various fields, including healthcare, rehabilitation, and human-computer interaction.

Answer
At what point after traumatic brain injury, stroke, etc. will the rehabilitation begin?  Improvements in cognitive functioning may occur for quite some time after an event, but these may be related to various factors other than a specific rehabilitation approach.  Also, what is your definition of "cognitive rehabilitation?"  How will you know that you have succeeded in reaching your goal?  The goal may be different depending on the type of neurological event that occurred, its severity, and how long it has been since the occurrence.

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.

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.
Relevant answer
Answer
I don't believe there is a standardized cut off score for GHQ-28.  Goldberg, Oldehinkel & Ormel (1998) had recommend that each researcher derive a cut off score based on the mean of their respective sample (Goldberg DP, Oldehinkel T, Ormel J (1998) Why GHQ threshold varies from one place to another. Psychol Med 28:915-921).  However, that is an old citation and there might be newer information.  The general cut off range reported from different cultures and countries seems to be similar, about 3/4 out of 28 items in most cases.
Also, I agree with comments from other colleagues - GHQ does not screen for psychiatric disorders.  In most of literature from UK you will read the term "psychiatric morbidity" associated with it, while in most literature in the US, it is used as a measure of "psychological distress".  The former term suggests propensity for mental illness, while the latter term suggests a more "normative" distress state.  Looking at the individual items, you can see that it more likely taps on current signs of stress, anxiety or depressed mood which may or may not be clinically significant. 
Hope this is helpful.

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.

You can gather useful information in the international FES society website (http://www.ifess.org). There's an education section that might prove useful for those not familiar with FES concepts. And there's also an open access repository of the IFESS conference proceedings.

Question

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?
Relevant answer
Answer
I agree with Catherine on the need to work on acceptance in many cases. The problem [and this is my main point] is that acceptance is not as simple as it sounds. On the contrary it is an emotionally dynamic process, highly complex, for the patient [his family] and the therapists as well. I believe that more training [and the development of models] on this matter is needed. So professionals can facilitate this process and avoid interventions that are iatrogenic.

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?
