Artificial Intelligence: A Revolution in Rehabilitation?

Artificial Intelligence (AI) is transforming how medical professionals approach rehabilitation, offering innovative tools that enhance the quality of treatment. At ISICO, we are increasingly committed to exploring how AI can support daily clinical work and contribute to highly personalised therapeutic decisions.

We discussed this with Francesco Negrini, a specialist physiatrist at ISICO and the author of a groundbreaking 2023 study on AI and rehabilitation. This study, “Developing a new tool for scoliosis screening in a tertiary specialist setting using artificial intelligence: a retrospective study on 10,813 patients,” won the prestigious SOSORT Award in 2023.

Dr Negrini recently presented another paper exploring the use of AI in rehabilitation projects, particularly in stroke recovery.

What Are the Key Areas Where AI Can Be Used in Rehabilitation?
Artificial Intelligence (AI) is incredibly versatile and can be applied at various stages of the medical process. It can range from diagnosis, using automated analysis of X-ray or MRI images to identify pathologies with greater precision, to prognosis, with predictions on treatment outcomes, and on to the personalisation of treatments, determining the most effective therapeutic pathway based on patient data. AI also enables continuous monitoring, allowing real-time patient progress evaluation to adapt the treatment accordingly.
At ISICO, we are exploring, for example, how AI can support personalised treatment approaches. This technology could analyse a patient’s natural history and the likelihood of success when using one type of brace over another, providing physicians with more accurate decision-making tools.

Can you give a concrete example of how ISICO is using AI?
A significant example is the research that won the SOSORT Award 2023, recently published (link). The study demonstrated how analysing clinical data using advanced techniques can enhance our understanding of scoliosis and its treatments.

Another potential application involves the diagnosis of low back pain, where AI can analyse radiographic images to identify aetiologies that the human eye might otherwise miss. This approach takes advantage of today’s enhanced computational power, enabling the rapid and accurate processing of large volumes of data.

How Could AI Transform the Management of Spinal Disorders in the Future?
There are three key areas where we see tremendous potential. The first is screening and early diagnosis, which involves early detection of scoliosis or other conditions to improve treatment outcomes. The second area is the customisation of braces, using data collected from clinical centres to predict which type of brace will be most effective for a specific patient. Lastly, monitoring outcomes plays a crucial role, as it allows for tracking the progress of therapy and adapting it based on observed improvements, thereby enhancing the overall effectiveness of treatment.

What Makes AI Such a Valuable Ally for Clinicians?
AI amplifies a clinician’s capabilities, providing more detailed information and helping them make data-driven decisions. However, as we always emphasise at ISICO, the doctor-patient relationship remains central. AI does not replace a clinician’s experience and empathy; instead, it offers tools that enhance human expertise.

What is the Future of AI in Rehabilitation Medicine?
I believe we will see an increasingly close integration of AI in clinical practice. At ISICO, we are moving in this direction, exploring how AI can improve therapeutic outcomes and make rehabilitation more targeted. We are just at the beginning, but the possibilities are immense, especially if we can combine the best of technology with the invaluable expertise of healthcare professionals.

SOSORT Award: Isico is back on the podium!

And once again, the winner is… Isico! For the fifth consecutive year, our institute has been awarded the prestigious SOSORT Award, recognising our innovative and cutting-edge research focused on Artificial Intelligence in the rehabilitation treatment of the spine. The winning research, titled “Developing a new tool for scoliosis screening in a tertiary specialist setting using artificial intelligence: a retrospective study on 10,813 patients,” was one of the eight Isico studies presented at the Sosort conference held in Melbourne, Australia, a few weeks ago.

This prize shows the quality of research conducted at Isico, combining scientific evidence with daily clinical practise to enhance rehabilitation treatment for patients worldwide. Dr. Francesco Negrini, a physiatrist and author of the study, explains the motivation behind the research: “We sought to explore ways to reduce the need for radiographs while ensuring accurate and timely scoliosis screening. Through collaboration with engineers in Zurich, we employed advanced analysis methods using artificial intelligence to develop a model that accurately identifies cases warranting X-rays.”

This international collaboration enabled Isico to harness innovative technologies and present research able to achieve this prestigious recognition. Dr. Negrini further emphasises the significance of the prize, stating, “I am immensely satisfied with this achievement. It reaffirms the validity and excellence of Isico’s scientific dedication, paving the way for a reduction in the number of X-rays prescribed to patients while maintaining optimal care.”

Dr. Sabrina Donzelli, the next president, tells us about the SOSORT conference

Once again, the international SOSORT conference was one of the most important appointments for our institute (eight abstracts were presented), and with a cherry on top, the fifth SOSORT Award was won!
We asked Dr Sabrina Donzelli, physiatrist and president of SOSORT in 2024, the first woman to hold this position, to tell us something more about the event, given that she was one of the three Isico specialists present in Melbourne (the others were Dr Fabio Zaina and our director of physiotherapy, Michele Romano).

1) What did participating in this event mean to you?
For the first time, SOSORT participated in Spineweek. Spineweek is an event that occurs every four years and brings together many societies dedicated to various aspects of the spine. This event allows participants to follow different companies by participating in a single event. It provides the other companies involved greater visibility or the possibility of being known and attracting new members.
The event was a success for SOSORT thanks to the number of participants and presentations. SOSORT is growing, and this experience was another opportunity for growth for the company, which is preparing to organize its first annual congress with total autonomy.

2) What were the major scientific innovations?
Dr Angelo Aulisa presented a remarkable study on the efficacy of braces in patients with Scheuermann with a 10-year follow-up. It is the first study to explore this area with such an extended follow-up.
Comparison studies are starting to emerge, for example, between braces at different dosages or nighttime bracing compared with exercises only; unfortunately, the quality of these studies is limited, and the results still need to be evaluated with caution.
We are also witnessing an increasing collaboration between surgery and rehabilitation treatment in a great communication effort to learn how to manage better patients who have surgical indications and those who would like a surgical approach but could benefit from conservative treatment. The president of the SRS (Scoliosis Research Society), Dr Serena Hu, showed the innovations in the surgical field; indeed, there are still many challenges to reducing invasiveness with the same effectiveness.

3) The SRS also has a female president for the first time, and your successor in the SOSORT presidency is the Croatian doctor Suncica Bulat Wuerching. There are more and more women, so how are you experiencing this moment of transition to your presidency?
We women play a fundamental role in the scientific world, like our colleagues, and this can only fill me with satisfaction for the work we carry out with great determination and professionalism. In terms of my position, it will be a great responsibility to lead the company through this transition. Still, I am delighted to work with a fantastic team of professionals, starting with the current president, James Wynne.

Scoliosis screening: the ISICO study on artificial intelligence in the running for the SOSORT Award

Developing a new tool for scoliosis screening in a tertiary specialist setting using artificial intelligence: a retrospective study on 10,813 patients is one of the ISICO studies due to be presented at the next SOSORT conference, which will take place in Melbourne, Australia. The fact that the study is also a candidate for the SOSORT Award consolidates the standing of ISICO, which in recent years has not only participated with its research but also been awarded this prestigious prize on several occasions. 

In recent years, we have seen an increasing body of evidence supporting the efficacy of conservative treatment (e.g., exercises, soft and rigid braces) for adolescent idiopathic scoliosis (AIS), because treating a skeletally immature spine conservatively is certainly more effective and gives better results. The use of the conservative approach, however, has to be based on accurate and sensitive early screening for the condition, which often involves the use of X-rays.

What can be done to continue screening patients while at the same time making less use of X-rays? “Although technological improvements have, in recent years, made it possible to reduce the radiation dose in radiographic examinations, it is not possible to completely eliminate the long-term risk of cancer due to the stochastic effect of even low doses of radiation,” explains Dr Francesco Negrini, ISICO physiatrist and author of the research. “This is why we set out to analyse whether adding other rapid and reliable clinical parameters to the angle of trunk rotation (ATR°) might improve scoliosis screening in terms of sensitivity and specificity, making it possible to limit the use of X-rays to cases in which it is indispensable.”

How was the research conducted? The researchers looked at 10,813 patients between the ages of 4 and 18 who underwent clinical and radiological evaluation for scoliosis at a tertiary clinic specialising in spinal deformities. After excluding patients who wore a brace, had secondary scoliosis, or had no hump, 7,378 cases remained and were included in the analysis. In these cases, the following information was collected: ATR°, hump (mm), visible asymmetry of the waist, scapulae and shoulders, family history, sex, BMI, age, menarche (yes/no), and location of the curve. “At this point, we applied advanced analysis methods involving the use of artificial intelligence to try and create a model that would allow us to accurately select the cases needing to be X-rayed,” Dr Negrini goes on, “and we identified ATR°, hump (mm) and visible waist asymmetry as the clinical parameters best able to accurately classify Cobb angle measurements.”

On the basis of this conclusion, the researchers were able to affirm that classification models obtained through artificial intelligence may effectively improve non-invasive screening for AIS, thereby making it possible to reduce the X-ray exposure of healthy young individuals. “On the basis of the positive results obtained in the study, we may, in the near future, be able to develop a very flexible and user-friendly tool” says Dr Negrini. “This would allow doctors working in this specialised field to decide to prescribe radiographic imaging only when it is strictly necessary.”

SOSORT Melbourne: 8 Isico abstracts

There are 8 abstracts, which will be presented by Isico at the annual Sosort international conference, held from May 1–5 in Melbourne, Australia.

Once again, Isico will be in the front row at the International SOSORT meeting, and one of the abstracts, entitled “Developing a new tool for scoliosis screening in a tertiary specialist setting using artificial intelligence: a retrospective study on 10,813 patients,” is also competing for this edition of the Sosort Award, which, as we recall, Isico won for several consecutive years. 
The other abstracts that will be presented by our expert physiatrists, Dr Sabrina Donzelli, and Dr Fabio Zaina, and by Michele Romano, Director of Physiotherapy at Isico, are:
Adherence to physiotherapeutic scoliosis-specific exercises during adolescence: voices from patients and their families: a qualitative content analysis;
Bracing interventions can help adolescents with idiopathic scoliosis with surgical indications:
A systematic review; SOSORT Guidelines for scoliosis conservative treatment: an update
It is worth treating an adolescent with idiopathic scoliosis when bone maturity has passed US Risser 2: Bracing can improve curves and aesthetics
– Outcome measures in scoliosis treatment: Is the Cobb angle enough?
– The apex vertebrae of the scoliotic curves; a study of their frequency in 11758 cases
– Evaluation of thoracic flexibility in the sagittal plane with the Thoracic Stiffness Test: intra- and inter-operator reliability


Therefore, a reconfirmation for Isico with full marks among the best researchers in the world in the rehabilitation treatment of spinal pathologies.

SOSORT 2022: a feedback by dr Sabrina Donzelli, the next president of SOSORT

We asked physiatrist Dr Sabrina Donzelli, one of our doctors at ISICO, to tell us about the highlights and significance of SOSORT, the international conference held at the start of May in San Sabastian.
We knew that the event would be an important occasion for the specialists in attendance, as they had not been able to meet in person for two years. Little did we imagine, though, when we approached Dr Donzelli, that we were asking the very person who, in the course of the event, would be named as the next President of SOSORT. The presidency of this association is a highly prestigious role. This is the fourth time an ISICO member has been chosen for the position, and Dr Donzelli is the first woman to have the honour.

We therefore begin this interview by extending our congratulations to Dr Donzelli.

1) Wow! Well, this was great news on two levels: first, because the position will once again be held by an ISICO member, and second, because this is the first time a woman has been chosen. The International Society has grown considerably over the years and now has a large membership with a good balance of men and women, even though this is not so true of the single professions. There aren’t many doctors in SOSORT; most of its members are physiotherapists. If you aspire to be President of SOSORT, you have to serve the organisation, putting in years of voluntary work. For some years now, I have been committed to doing all I can for SOSORT because I share its vision and its mission: to ensure that patients with scoliosis always receive the best treatment based on the scientific evidence. It is therefore important to be committed to research and to spreading knowledge. In other words, the mission is also to educate. My commitment and willingness have helped me become widely appreciated within the society, allowing me to join the executive board in 2019, and to be made President Elect this year. 

2) What did it mean, after three years, to finally be meeting in person, with colleagues all in one place rather than scattered around the world?

SOSORT, which dates back to as long ago as 2004, was created to bring together the world’s leading experts in the field of rehabilitation treatment for spinal disorders, to allow them to “compare notes” and increase the level of scientific evidence in the field, as well as improve the treatments available to patients. Over time, its missions and aims have been and continue to be updated, because medicine is a constantly evolving science. The last proper congress was held in San Francisco in 2019, after which the event moved online for a couple of years. It was therefore fantastic finally being able to get together in person again. We were able to talk face to face and really share, all together, our passion for what we do and our everyday challenges. All this is reflected in the slogan that was used to announce and promote the event: SOSORT 2022 – More than a congress: an experience in San Sebastian. You will never forget it! 

3) What are the main scientific developments you were able to take away with you? 

Epigenetics appears to be the future when it comes to improving understanding of scoliosis and trying to identify individuals at risk of developing it. Obviously, there is still a huge amount of work to be done, but at present this seems to be the way to go. 

Second, ultrasound is the future of radiation-free diagnostics, albeit perhaps not so much when applied to the spine as when used to estimate residual growth. In this regard, I should mention an interesting study by  Sanders based on ultrasound of the hand, Bracing outcomes in end-of-growth patients. Evidence to support the use of braces even towards the end of growth: it’s not too late to wear a brace.
Indeed, other studies similar to ours have shown that good results can be obtained even at the end of growth. There is also promising scientific evidence in patients who have finished growing: we at ISICO were the first to present these findings, and now other groups, too, are showing that good results are possible even in individuals with advanced bone growth. 

It is worth considering that three of the six studies in the running for the SOSORT Award dealt with outcome prediction: they ranged from Dr Lori Dolan’s study with 10-year follow up after the end of bracing treatment to our research conducted in collaboration Dr Eric Parent of the University of Alberta, in Canada, in which we attempted, in patients observed over time, to predict future curves solely on the basis of X-rays performed before they started treatment with braces or exercises. 

4) SOSORT Award: were there any surprises?

Not at all. The winning study was the strongest methodologically. The paper, on which we collaborated with the University of Alberta, illustrated a prediction model developed on the whole sample: it has some limits related to the heterogeneity of the data, which reflects that of scoliosis itself. Each patient has their own clinical history and this makes it difficult to predict how the disease will evolve in relation to age, time since onset, and residual bone growth estimated using the Risser classification. 

The Bracing in Adolescent Idiopathic Scoliosis Trial (BrAIST), on the other hand, is a fundamentally important study: it has demonstrated the therapeutic effectiveness of braces and shown that follow up over time is essential in order to advance the study of scoliosis. The monitoring of the patients observed and treated by these researchers will continue to give us important information, while the methodological rigour of their study is a guarantee of very reliable scientific evidence.

Isico’s research wins the SOSORT Award

For the fourth consecutive year, Isico has obtained the most prestigious award for those involved in rehabilitative treatment of the spine, winning the SOSORT Award with the study Prediction of Future Curve Angle using Prior Visit Information in Previously Untreated Idiopathic Scoliosis: Natural History in Patients under 26 Years Old with Prior Radiographs.

The research, which involved 2317 patients with idiopathic scoliosis between 6 and 25 years old, was developed by our researchers (the Isico authors are Prof. Stefano Negrini, together with Dr Giulia Rebagliati, Dr Fabio Zaina, Dr Sabrina Donzelli and Dr Alberto Negrini) in collaboration with Dr Erik Parent of the University of Alberta, Canada. This project was funded by a Standard Research Grant from the Scoliosis Research Society.

“Understanding natural history helps inform the treatment selection for modifying the course of the disease or to avoid overtreatment – explains prof. Stefano Negrini, Isico Scientific Director- Previous models predicting curve progression lacked validation, did not include the full growth spectrum or included treated patients. Our aim was to develop and validate models to predict future curve angles using clinical data collected only at, or both at and prior to, an initial specialist consultation in idiopathic scoliosis”. 

Scoliosis-specific exercises are recommended in small curves in skeletally immature patients, exercises and progressively more aggressive brace treatments are recommended for moderate and severe curves in 10% of growing children and adolescents and invasive corrective surgery is recommended in severe curves at risk of continued progression in adulthood for 0.1-0.3% of cases. 

“Patients were previously untreated and provided at least one prior radiograph prospectively collected at first consult – continues prof. Negrini – We excluded those previously treated”.

 Radiographs were remeasured blinded to the predicted outcome: the maximum Cobb angle on the last radiograph while untreated. Linear mixed-effects models with random effects and maximum likelihood estimate were used to examine the effect of data from the oldest visit (age, sex, maximum Cobb angle, Risser, and curve type) and from other visits while untreated (Max Cobb angle), and time (from oldest radiograph to prediction) on the Cobb angle outcome.

“Predictions models were proposed which can help clinicians predict future curve severity expected in patients not receiving treatment –ends prof. Negrini – Predictions can inform treatment prescription or show families why no treatment is recommended. Our models offer the flexibility to predict at a future timepoints over the full growth period. These validated models predicted future Cobb angle with 80% of predictions within 100 in non-treated idiopathic scoliosis over the full growth spectrum. Improved prediction ability may help clinicians inform treatment prescription or show families why no treatment is recommended”.

SOSORT 2022: the AWARD winners and a fourth ISICO President

This year’s SOSORT meeting, held in San Sebastian, Spain in the wake of two editions forced online by the pandemic, was a double success for ISICO, which had two studies shortlisted for the SOSORT Award.
One of them, Prediction of Future Curve Angle using Prior Visit Information in Previously Untreated Idiopathic Scoliosis: Natural History in Patients under 26 Years Old with Prior Radiograph, conducted in collaboration with the University of Alberta in Canada, came first, making this the fourth consecutive year that ISICO has taken home the prestigious award. But this was not the only high point. Our Dr Sabrina Donzelli, physiatrist, was named as the next President of the International Society. This is the fourth time that ISICO has had this has honour since SOSORT was founded in 2004,  and it is the first time a woman has been appointed to the role.

“This prestigious appointment is an acknowledgement of Dr Donzelli’s scientific standing, hard work and commitment, as well as a recognition of our institute, which now provides a benchmark for clinical and research activity worldwide” remarked Prof. Stefano Negrini, Scientific Director of ISICO as well as one of the ISICO authors — the others being De Giulia Rebagliati, Dr Fabio Zaina and Dr Alberto Negrini — who collaborated with Dr Eric  Parent, first author of the study that won the SOSORT AWARD. The congress was hugely stimulating and we can’t wait for 2023 and next year’s meeting in Melbourne, Australia”.

The winning study of the SOSORT Award 2020 has been published

Two years after winning the SOSORT AWARD, the study “Predicting final results of Brace Treatment of Adolescents with Idiopathic Scoliosis: First Out-of-Brace are Better than In-Brace-radiographs” has finally been published in the European Spine Journal.

 A total of 131 patients were included in the study, the researchers aimed to determine which of the two radiographs is the best predictor of the Cobb angle at the end of treatment (final radiograph). In fact, the in-brace radiograph of adolescents with idiopathic scoliosis (AIS) has been shown to reflect brace efficacy and the possibility of achieving curve correction. Conversely, the first out-of-brace radiograph could demonstrate the patient’s ability to maintain the correction.

The first out-of-brace radiograph predicts end results better than the in-brace radiograph.

“Our research has highlighted – explains Dr. Sabrina Donzelli, author of the research – how important the first x-ray taken without the brace is in predicting end-of-care results. The first out-of-brace radiograph should be considered an essential element of future predictive models and offers an excellent clinical reference for clinicians and patients. The collection of clinical data that occurs routinely during all visits to ISICO has allowed in recent years to be able to develop the so-called predictive models, i.e. we can use the characteristics of the patient to understand how the final results can be predicted or to understand if there are risk factors more important than others to consider when deciding what type of therapy to prescribe “.

eSosort2021: ISICO awarded for the third time in a row

And the winner is: Isico! For the third consecutive year, our Institute has been awarded the highest international recognition for those involved in the rehabilitation treatment of vertebral pathologies. On Saturday, May 1st, on the occasion of the annual SOSORT conference, this year in online mode due to the pandemic, our studio “Efficacy of bracing in infantile scoliosis. A 5.5 years prospective cohort shows that idiopathic respond better than secondary” was awarded the SOSORT Award. 

It is not the first time, because only in the last two years Isico has won the coveted international recognition for the best research by SOSORT, to which is added, in 2019, the award won as co-authors of a research study in collaboration with the University of Hong Kong. A truly unique continuity.
“An award that once again certifies the high quality achieved by the scientific research carried out in our Institute at an international level – explains Prof. Stefano Negrini, scientific director of Isico and first author of the awarded research (the other authors are Dr Sabrina Donzelli, Dr Greta Jurenaite, Dr Francesco Negrini and Dr Fabio Zaina) – through this research the main goal was we have set ourselves the goal to check the results in the medium term of bracing of infantile scoliosis, comparing the two groups: idiopathic and secondary scoliosis.”
According to Mehta results, casting is considered the gold standard conservative treatment for infantile scoliosis, still casting requires repeated general anaesthesia, and recently doubts have been raised that this could cause potential brain damages in the long term. 

“In our Institute, we have been using bracing for a long time to reduce invasivity for the patient – says Prof. Negrini – Moreover, the results of the Sforzesco brace have shown to be similar to casting in adolescents. Thanks to the clinical and research experience gained over the years, we have developed a retrospective study in a prospective cohort. We have been using braces since 2004 and have been able to present the largest case history on braces to date (34 patients), with an average follow-up of 5 years, documenting excellent results in idiopathic scoliosis (success in 50% of cases – only one failure), while in those secondary to other pathologies it is possible to delay surgery over time even in the face of more frequent failures (surgery inevitable in 20% of cases)”.
We remind you that infantile scoliosis is very rare, about 1 case in 10,000 children, and for this reason, it must be treated by very expert and dedicated specialized clinics with specialists who  have been managing spine deformity for long and have a rich clinical experience
“In this context, we are also the only Italian structure that is participating in an international multicentre study, which involves clinical centres in 40 countries around the world, to verify the effectiveness of braces compared to casts – concludes prof. Negrini – During the two-year duration of the project, we will bring about 5 cases treated at our Institute for research purposes. Isico has several years of experience in the use of braces, our participation will not include the application of casts, but our results in bracing will be compared with those of other centres that apply casts”.
