Dr Hans-Rudolf Weiss – Developing Innovative and Effective Non-surgical Therapies for Scoliosis

Apr 27, 2022 | Medical & Health Sciences

Scoliosis, the curving of the spine, is a relatively common condition that develops in early adolescence. Whilst there are surgical options to neutralise the curve, there is no solid evidence for its long-term impact. Dr Hans-Rudolf Weiss is an expert in scoliosis treatments and has dedicated his research to improving the care of scoliosis patients. Through his back brace innovations and novel exercise therapies, he has developed ground-breaking new standards of care for patients. Additionally, through his Schroth Best Practice program, he is educating a new generation of doctors and physiotherapists on his non-surgical methods.

Scoliosis: Symptoms and Treatments

Scoliosis is a curving of the spine that usually appears in young adolescence and can become more severe as a child grows. As the spine curve becomes more prominent, the space within the chest is reduced, and this can impact the function of the lungs and create breathing difficulties in a small proportion of patients. Other scoliosis symptoms include uneven shoulders and waist, one shoulder blade or hip appearing more prominent than the other and one side of the rib cage being obviously pushed forward. This is because the condition usually causes rotation of the spine in addition to the curve.

The exact causes of scoliosis are unclear but as it sometimes runs in families, it may be a hereditary disease. However, some types form as a result of birth defects, injuries and neuromuscular conditions like cerebral palsy. X-ray or magnetic resonance imaging scans can be used to definitively diagnose scoliosis and to determine the severity of the spinal curve. For some children, the condition may be mild enough to not require treatment but others will need help to straighten their spine in order to prevent severe back pain and other complications in the future.

Some children are provided with a back brace, which, according to current standards and qualities, usually does not reverse the curve but can stop it from getting worse and is worn until they stop growing. For severe scoliosis, surgery may be performed. Spinal fusion surgery involves connecting some of the spinal bones (vertebrae) and using a metal rod to keep the pieces still to allow them to fuse. Alternatively, in a procedure called vertebral body tethering, screws and a flexible cord is attached to the spine which can be tightened to straighten the spine.

Investigating What We (Think We) Know

Although these treatments are frequently used for scoliosis patients, the long-term effectiveness of surgery is not well-evidenced and more research is needed to improve care. Dr Hans-Rudolf Weiss is an orthopaedic surgeon, physical medicine practitioner and chiropractor in addition to serving as Senior Consultant at Koob Scolitech GmbH in Neu Bamberg, Germany. In his research, he leads an innovative team to build upon our understanding of scoliosis treatments and to develop exciting new treatment methods.

Dr Weiss is the grandson of Katharina Schroth, who developed the ‘three-dimensional scoliosis treatment according to Schroth’ which utilises patient-customised exercises to de-rotate, elongate and stabilise the spine. Through this method, the spine is eased into a more neutral position in its three-dimensional plane. This renowned family background inspired Dr Weiss to build upon existing knowledge and push forward the field of scoliosis care.

Along with Professor Tugba Kuru Colak, Dr Weiss put together a special issue of the South African Journal of Physiotherapy, which covers their broad and in-depth range of scoliosis research. It includes topics such as assessing the reliability of established deformity classification methods and looking into the effect of specific styles of back braces. The issue also has an explorative study into using vision-based augmented reality to educate physiotherapy students on the spine and its possible deformities. It was shown to be a great success, with students demonstrating a significantly higher understanding of spinal anatomy, function and pathologies than control groups.

Another important paper in this issue is the critical appraisal conducted by Dr Weiss into what evidence is available to demonstrate the long-term effectiveness of scoliosis surgery. He carried out a comprehensive review of the available scientific literature surrounding spinal surgery and discovered that there is no evidence to support the claim that surgery is the best treatment option. This means that long-term variables and possible complications are unknown and therefore, doctors recommending surgery should carefully consider each patient’s case and risks. In addition, though, Dr Weiss says that a wider systematic review of spinal surgery patients is necessary to be able to confidently recommend it as a safe and effective treatment.

Even methods that are considered ‘conservative’ and less invasive (like back braces) are not fully backed by evidence. Back braces can be physically uncomfortable and even painful, which may lead to psychological discomfort and distress. Additionally, methods of brace application and selection are not standardised so patients may not be receiving equitable care. This is in part due to an incomplete consolidation of the scientific literature that could provide a more solid grounding for patient care. According to Dr Weiss, ‘too many contemporaries advertise their own methods without any scientific proof and ultimately cause their patients more disappointment than the joy of a successful treatment.’

As a result, in a narrative review of the literature for the special issue of the South African Journal of Physiotherapy, Dr Weiss found a wide range of success rates for the wide range of different brace applications. Nonetheless, he concluded there is sufficient evidence that back braces can stop curvature progression, improve spine and trunk appearance, and reduce the number of patients needing surgery. He subsequently provided recommendations for proper brace application and maintenance using appropriate information from each individual patient and a standardised computer-aided design. If implemented correctly, this should result in a less stressful and more safe treatment experience, with the best possible patient outcomes. Results should reflect a considerable proportion of patients demonstrating improved curves and significantly improved clinical results (cosmetics).

‘Confronted again and again with frightened, disappointed and misinformed children, adolescents and their parents, I felt the desire to change something. These experiences became the driving force behind my efforts to significantly improve non-surgical treatment measures and to make evidence-based information available to patients.’

The Schroth Best Practice Program

Dr Weiss sought to find additional solutions to what he felt were insufficient treatment options, and describes how ‘confronted again and again with frightened, disappointed and misinformed children, adolescents and their parents, I felt the desire to change something’. So, he improved upon existing guidance and built a guidebook for patients and family members to help them help themselves, explaining that ‘these experiences became the driving force behind my efforts to significantly improve non-surgical treatment measures and to make evidence-based information available to patients.’ The guidelines include a therapy for patients to learn postural awareness, thus helping them avoid behaviour that exacerbates the curving of their spines.

In addition to this therapy, Dr Weiss innovated a new back brace concept to overcome the issues that he had experienced as a doctor. This brace adopts a Chêneau style, which is asymmetric to accommodate the curved spine. It also utilises computer-aided design, which removes the need for traditional plaster casting and provides a highly patient-specific brace design. A patient’s trunk is scanned in 3D and their clinical measurements are input to the computer to create a brace model that is a perfect fit. Dr Weiss named this the Gensingen brace after the place in which it was designed and it has proven to be a success. Patients have described it as comfortable to wear, spine corrections have been achieved and they have contributed to a wider-spread improvement in treatment standards, especially for kyphosis and chronic back pain.

Collating his substantial research and progressive ideas, Dr Weiss created the Schroth Best Practice Program in 2010. This brings together his guidelines for scoliosis patients, his modernised exercise treatment and his novel brace designs to form a state-of-the-art teaching program through the Schroth Best Practice Academy. Dr Weiss is a Senior Instructor and Consultant at the Academy, founded in 2010 from small beginnings as a non-profit organisation to become the basis for the training of thousands of international therapists working in the treatment of patients with spinal deformities and making modern treatment techniques available worldwide.

The impact of this original approach can be seen in another paper included in the special issue of the South African Journal of Physiotherapy. In this case report, a young girl had developed severe scoliosis and was at high risk for her condition to significantly progress. Normally, she may have been referred for surgery, but in this case, her parental figures declined. Instead, she received a Genisngen brace and intensive treatment according to the Schroth Best Practice program. After 18 months, her treatment had prevented the curve of her spine from worsening and she maintained an improved cosmetic result. By turning down surgery, the patient also avoided the risk of a stiff spinal deformity that can happen as a result.

Although Dr Weiss says more long-term research is needed to corroborate these promising results, he believes this type of high-impact, conservative treatment should be implemented before surgery is considered. In this way, both known and unknown future complications may be avoided.

Dr Weiss’s extensive experience and research have led to ground-breaking new methods including the introduction of extracorporeal shockwave therapy to the treatment of scoliosis, and a new exercise programme aiming at the mobilisation of the spinal cord which might be tethered in certain forms of scoliosis. With positive results and an ongoing, thriving education program, his work has and will continue to change the landscape for what is the best practice for scoliosis patients and their care. This is sure to make a demonstrably positive impact in the lives of those developing and living with spinal irregularities, and their families, all around the world.

Professor Toni Miles | Why Understanding Bereavement Matters

Professor Toni Miles has dedicated her research efforts to measuring bereavement and its impact on population health. Individual experience with bereavement is commonplace, but we know little about its impact on society when there is an instantaneous experience by a large number of individuals, i.e., mass bereavement. To measure its occurrence, her research with colleagues first confirmed that bereavement can be effectively measured in population surveys. Professor Miles argues that we should use such approaches to deliver interventions aiming to reduce the negative consequences of bereavement on individuals. By measuring bereavement in communities, these data become a cost-effective way to increase resilience, reduce demands on healthcare systems, and enhance public safety.

Dr Omar Islam | Portable Magnetic Resonance Imaging: An Important Innovation

Imaging technologies are vital in modern medicine and have revolutionised how clinicians make diagnoses and monitor disease progression. However, the necessary equipment – such as a scanner for magnetic resonance imaging (MRI) – is very large and expensive, requiring patients to go to the scanner rather than receiving scans as bedside care. This takes up valuable staff time and resources, and can present further risks to patients. Dr Omar Islam from Queen’s University and Drs Aditya Bharatha and Amy Lin from the University of Toronto are showing how portable MRI scanners may offer a viable alternative that benefits patients and healthcare systems.

Professor Danny Reinberg – Dr Gary LeRoy | Confronting a Rare and Deadly Cancer in Children

A diagnosis of cancer is never welcome but is particularly devastating when a child is found to have diffuse intrinsic pontine gliomas – a rare but particularly aggressive and treatment-resistant malignancy in the brain. In this article, we focus on the contributions of Professor Danny Reinberg and Dr Gary LeRoy at the University of Miami-Miller School of Medicine to understanding what makes these tumours so dangerous and, importantly, to developing much-needed approaches to improve the outcomes for these children.
