In the randomized Conservative Treatment for Adolescent Idiopathic Scoliosis (CONTRAIS) trial, researchers, led by Anastasios Charalampidis, MD, PhD, with the Department of Clinical Science, Intervention and Technology at Karolinska Institutet in Stockholm, Sweden, tested whether a group using self-managed physical activity combined with either nighttime bracing for 8 hours or scoliosis-specific exercise achieved better results than a control group doing self-managed physical activity alone for 1 hour per day in preventing Cobb angle progression in moderate-grade AIS.
Findings of the trial, conducted in 6 public hospitals across Sweden, were published online in JAMA Network Open.
Night Bracing More Effective Than Comparison Arms
In the trial of 135 patients, aged 9-17 years, who were skeletally immature with moderate AIS, researchers found that night bracing plus self-managed physical activity prevented curve progression of more than 6 degrees (treatment success) to a significantly greater extent than did either self-managed physical activity alone or scoliosis-specific exercise.
A secondary outcome of curve progression was the number of patients who had surgery up until 2 years after the primary outcome.
The average age of patients was 12.7 years and most (82%) were female. Patients with treatment failure (curve progression of more than 6 degrees) had the option to transition to a full-time brace until skeletal maturity. That option resulted in similar frequency of surgery independent of initial treatment, according to the paper.
AIS is a structural deformity of the spinal column, affecting otherwise healthy children and adolescents during their growth spurt.
Previous studies have suggested that full-time bracing is effective in treating moderate-grade AIS. But the physical distress and psychological side effects that some experience can cause low adherence or rejection of the treatment.
The authors wrote that, “To our knowledge, there have been no randomized clinical trials investigating night bracing versus a control group.”
In this trial, treatment success was seen in 34 of 45 patients (76%) in the nighttime-bracing group and in 24 of 45 patients (53%) in the physical activity–alone group (odds ratio [OR], 2.7; 95% CI, 1.1-6.6). Success occurred in 26 of 45 patients (58%) in the scoliosis-specific exercise group (OR for scoliosis-specific exercise vs physical activity alone, 1.2; 95% CI, 0.5-2.8).
Adverse Events
Patients and clinicians could respond to an open-ended question regarding adverse events at each 6-month follow-up. Nineteen adverse events were reported in 15 patients between the start of the study up until the primary outcome was reached.
In the night-bracing group, there were 16 adverse events reported among 12 patients. They were: trunk pressure and skin problems (n = 10); sleeping problems (n = 2); emotional problems (n = 1); shoulder/neck pain (n = 2); and unspecified AEs (n = 1). In the scoliosis-specific exercise group, 3 adverse events were reported in 3 patients (pain during treatment (n = 1), muscle strain (n = 1), and low back pain (n = 1). No adverse events were reported in the physical activity alone group.
In an invited commentary, Kosei Nagata, MD, PhD, with the Department of Orthopaedic Surgery and Spinal Surgery at The University of Tokyo Hospital in Tokyo, Japan, said the study makes two important points.
“First, it was reaffirmed that the basis of scoliosis treatment is bracing and not a specific exercise therapy,” he wrote. “Second, nighttime bracing can be an effective alternative intervention for patients rejecting full-time bracing.”
He emphasized, however, that nighttime bracing alone is not enough to achieve success. In this study, bracing was combined with exercise. And the number of hours worn is important.
“Physicians should explain to patients with AIS and to their guardians the significant association between hours of brace wear and treatment success,” Dr. Nagata wrote. He pointed out that, in a previous randomized clinical trial in 2013 by Weinstein et al., patients were instructed to wear a brace for at least 18 hours a day. The treatment success rates of brace-wearing patients were 40% for less than 6 hours each day; 70% for 6-12 hours each day, and 90% for more than 13 hours each day, which suggests that full-time bracing is optimal.
However, he added that physicians should keep in mind the sensitivities of youth and effect on their self-esteem when prescribing bracing, as many adolescents will have a fear of ridicule.
“The goals of bracing treatment for AIS are manifold: avoiding surgical treatment, preventing future back pain, maintaining respiratory function, and reducing the psychological impact of the deformity,” Dr. Nagata wrote. “Physicians should understand these aspects and take a balanced view of patients who refuse full-time bracing.”
He added that future improvements in design of the braces and less rigid alternatives will be important.
The trial was funded by the Swedish Research Council and by the Stockholm County Council, the Swedish Society of Spinal Surgeons, the Karolinska Institutet and the Crown Princess Lovisas Foundation. Study coauthor Paul Gerdhem, MD, PhD, reports grants from the Karolinska Institutet beyond his usual salary during the study and personal fees for lectures from DePuy Synthes and grants from Philips Healthcare paid to the institution outside the submitted work. No other disclosures were reported. Dr. Nagata reported no relevant financial relationships.
