The history of Cheneau bracing dates back to the work of Dr. E.G. Abbott of Portland, Maine in the early twentieth century (1907). Dr. Abbott used plaster jackets in an attempt to affect derotation in scoliosis patients (1). His work influenced Dr. Jacques Chêneau of France, who began the Cheneau concept of scoliosis bracing.
In his quest to advance and improve scoliosis bracing, Dr. Chêneau traveled to Sobernheim, Germany (now Bad Sobernheim) in the 1970s to visit the scoliosis clinic of Katharina Schroth and Christa Lehnert-Schroth, PT. Dr. Chêneau wanted to learn more about Schroth corrective breathing and Christa Lehnert-Schroth’s Classification System (2).
In 1979, Dr. Chêneau developed the first Cheneau orthosis, using bracing concepts that are wholly compatible with Schroth corrective exercises. Some notable features of Cheneau-style braces are openings positioned at the spinal concavities and corrective pressure points according to Schroth’s curve-pattern classifications.
Dr. Chêneau was the first brace developer to recognize that idiopathic scoliosis generally involves thoracic lordosis, which should be treated accordingly (2). Cheneau bracing and Schroth method exercises both focus on correction in the three planes of scoliosis: the coronal, transverse and sagittal planes.
In the 1990s, Dr. Hans-Rudolf Weiss (3rd generation Schroth family member) hosted courses at the Katharina Schroth clinic (named for his grandmother). At the time, Dr. Weiss was serving as the medical director and invited Dr. Chêneau to the clinic to demonstrate his bracing concepts to other European practitioners, including Dr. Manuel Rigo of Barcelona, Spain. Dr. Weiss went on to train and work with Dr. Rigo. The two eventually parted ways and Rigo adopted his own classification system. The Cheneau concept eventually spread throughout Europe (2). At the time, Cheneau braces were being fabricated from a mold of a patient’s torso created by casting.
Dr. Weiss went on to develop his ‘Cheneau Light®’ Brace. As medical director at the Katharina Schroth Clinic, Dr. Weiss oversaw the in-patient Schroth program and fit thousands of adolescents with the Cheneau-derived brace. The Cheneau Light®’ Brace has a record of improved patient satisfaction and favorable outcomes, reducing the need for scoliosis surgery (3). With the advent of CAD/CAM technology, Dr. Weiss has been able to advance the Cheneau concept even more, leading to the newest model – the Gensingen Brace (GBW).
Cheneau Bracing Evolves with the Gensingen Brace
Bracing design and manufacture evolved to a higher standard with the advent of CAD/CAM. Dr. Weiss was an early adapter of CAD/CAM design. Over his thirty-plus year career treating scoliosis, Dr. Weiss has amassed an extensive library of curve patterns, in accordance with the Christa Lehnert-Schroth Augmented Classification based approach (CBA) (4). Each Gensingen Brace is custom-designed from that extensive library, which is constantly updated for delivery of the best possible brace.
An important benefit of CAD is brace standardization. Standardization eliminates the opportunity for error and practitioner interpretation during the Cheneau brace-making process. Each brace is designed and fabricated to have a built-in correction effect according a patient’s individual curve pattern. The customized design allows for a more exacting fit, that is both effective and tolerable for the patient, contributing to improved corrections (5).
This asymmetric 3D brace is suitable for patients with mild, moderate and severe curves (6). The GBW aims to overcorrect the spine, positively influence vertebral rotation, and improve posture in scoliosis patients. The Gensingen Brace has been shown to offer excellent in-brace corrections (7), which has been deemed an important aspect for the success of scoliosis bracing (8).
Today, there are several Cheneau derivates but very few have documented their bracing advancements to the extent that Dr. Weiss has with respect to in-brace results, nor does any Cheneau concept brace have as widespread usage internationally.
