Effects of hip brace on coxa valga in nonambulatory children with cerebral palsy: A randomized controlled trial.

BACKGROUND: Coxa valga, measured as the neck-shaft angle (NSA) or head-shaft angle (HSA), is regarded as a potential risk factor for hip dislocation in patients with cerebral palsy. We investigated the effects of a novel hip brace on coxa valga. METHODS: A prospective, multicenter, assessor-blinded, randomized controlled trial was conducted from July 2019 to November 2021. Children with cerebral palsy aged 1 to 10 years with Gross Motor Function Classification System levels IV and V were recruited. The study group wore a hip brace for at least 12 hour a day. A lower strap of the hip brace was designed to prevent coxa valga biomechanically. The effectiveness of the hip brace on coxa valga was assessed by measurement of the NSA and head-shaft angle at enrollment and 6 and 12 months after enrollment. RESULTS: Sixty-six participants were enrolled, and 33 patients were assigned to each group. Changes in the mean NSA of both sides and the NSA of left side showed significant differences between the 2 groups over 12 months (mean NSA of both sides, -1.12 ± 3.64 in the study group and 1.43 ± 3.75 in the control group, P = .023; NSA of the left side, -1.72 ± 5.38 in the study group and 2.01 ± 5.22 in the control group, P = .008). CONCLUSIONS: The hip brace was effective in preventing the progression of coxa valga and hip displacement, suggesting that the prevention of coxa valga using hip brace is a contributing factor in prevention of hip displacement.

Korean Version of the Longer-Term Unmet Needs After Stroke Questionnaire.

OBJECTIVE: : To translate the 22-item Longer-term Unmet Needs after Stroke (LUNS) questionnaire, validate it in the Korean stroke population, and assess the reliability of face-to-face and telephone surveys. METHODS: : Sixty-six adult patients with stroke from Seoul National University Bundang Hospital and Kangwon National University Hospital were involved in the validation. Participants were interviewed twice using the LUNS Korean version: first, a face-to-face survey for validation, and second, a telephone survey for test-retest reliability. Participants completed the Frenchay Activities Index (FAI) and Short Form 12 (SF-12) Mental and Physical Component Summary (MCS and PCS) scores at the first interview. For concurrent validity, the differences in health status (FAI, SF-12 MCS and PCS) between the groups that reported unmet needs and those that did not were analyzed for each item. Cohen's kappa and percentage of agreement between the first and second administrations were calculated for each item to determine the test-retest reliability. RESULTS: : The average age of the participants was 61.2±12.8 years and 74.2% were male. Fifty-seven patients were involved in the second interview. Depending on the unmet needs, SF-12 MCS, PCS, and FAI were significantly different in 12 of 22 items. In the test-retest reliability test, 12 items had a kappa of 0.6 or higher, and two had a kappa of <0.4. CONCLUSION: : The LUNS instrument into Korean (LUNS-K) is a reliable and valid instrument for assessing unmet health needs in patients with stroke. In addition, telephone surveys can be considered reliable.

Efficacy of a Hip Brace for Hip Displacement in Children With Cerebral Palsy: A Randomized Clinical Trial.

Importance: There is no consensus on interventions to slow the progress of hip displacement in patients with cerebral palsy. Objective: To investigate the efficacy of a novel hip brace in preventing progressive hip displacement in patients with cerebral palsy. Design, Setting, and Participants: This 2-group randomized clinical trial was conducted at 4 tertiary hospitals in South Korea from July 2019 to November 2021. Participants included children aged 1 to 10 years with nonambulatory cerebral palsy (Gross Motor Function Classification System level IV or V). Block randomization was used to assign an equal number of patients to the study and control groups via computerized random allocation sequences. Data were analyzed from November to December 2021. Interventions: The intervention group wore the hip brace for at least 12 hours a day for the study duration (ie, 12 months). Follow-up evaluations were performed after 6 and 12 months of wearing the brace. Both groups proceeded with conventional rehabilitation therapy during the trial. Main Outcomes and Measures: The primary outcome was the Reimers migration index (MI) on radiography, as assessed by 3 blinded investigators. Primary outcome variables were analyzed using linear mixed models. Secondary outcomes include change in the Caregiver Priorities & Child Health Index of Life with Disabilities, on which lower scores indicate better quality of life. Results: A total of 66 patients were included, with 33 patients (mean [SD] age, 68.7 [31.6] months; 25 [75.8%] boys) randomized to the intervention group and 33 patients (mean [SD] age, 60.7 [24.9] months; 20 [60.6%] boys) randomized to the control group. The baseline mean (SD) MI was 37.4% (19.3%) in the intervention group and 30.6% (16.3%) in the control group. The mean difference of the MI between the intervention group and control group was -8.7 (95% CI, -10.2 to -7.1) percentage points at 6 months and -12.7 (95% CI, -14.7 to -10.7) percentage points at 12 months. The changes in the Caregiver Priorities & Child Health Index of Life with Disabilities were favorable in the study group and reached statistical significance at the 6-month follow-up compared with the control group (difference, -14.2; 95% CI, -25.2 to -3.3). Conclusions and Relevance: In this randomized clinical trial, the novel hip brace was significantly effective in preventing the progression of hip displacement, compared with the control group. It effectively improved quality of life in patients with nonambulatory cerebral palsy. Therefore, hip brace use could be a promising treatment method to delay hip surgery and improve the quality of life of patients with nonambulatory cerebral palsy.

Asymmetrical activation and asymmetrical weakness as two different mechanisms of adolescent idiopathic scoliosis.

There have been many studies on adolescent idiopathic scoliosis related abnormal muscle contractions of the spine. However, previous studies using surface electromyography to investigate paraspinal muscle asymmetry are controversial, lacking in clarity of results, and hindered by methodological limitations. The purpose of this study was to investigate the relationship between imbalance factors including surface electromyography activity according to the scoliosis curve type and leg length discrepancy and adolescent idiopathic scoliosis curve types. Seventy-nine patients with scoliosis were prospectively enrolled and were divided into five types: single thoracic, thoracolumbar, lumbar, double thoracic, and double major. Cobb angle and structural variables were measured. Surface electromyography examinations were conducted at the 7th, 12th thoracic erector spinae, 3rd lumbar erector spinae, and multifidus muscles during the superman position keeping prone spinal extension to lift the arms and legs off the floor. Whole spine radiographs were obtained to measure the Cobb angle, coronal imbalance, pelvic height and angle, and femoral head height. In the double major, thoracolumbar, and lumbar types, the mean root mean squared (RMS) EMG amplitudes were significantly higher on the convex side than the concave side (P < 0.005). In the DM type, the mean RMS EMG amplitudes of EST7 and ESL3 where the apex was located were significantly higher at the convex side than those of the concave side (P < 0.005, effect size (Cohen's d) for EST7/ESL3: 0.517/0.573). The TL and L types showed a similar pattern. The mean RMS EMG amplitudes of the EST12 concave side and MuL3 and ESL3 concave sides were significantly lower than those of the convex side in the TL and L types, respectively (P < 0.008, effect size (Cohen's d) for EST12/MuL3/ESL3: 0.960/0.264/0.448). Conversely, there were no significant differences in the single thoracic and double thoracic types. All structural variables (coronal imbalance, pelvic height and angle, and femur head height) were higher in the lumbar type, but only coronal imbalance was significantly different (P < 0.05). Different patterns of asymmetry of paraspinal muscles and structural variables were described based on the curvature of the spine. L type showed that EMG activity was asymmetric in the paraspinalis muscles where the apex was located and that structural asymmetry, such as coronal imbalance was significantly greater than other types. DM type showed similar paraspinalis asymmetry pattern to the ST type but there was no structural asymmetry in DM and ST types. TL type has the features of both thoracic and lumbar origins. Understanding these could contribute to the management in correcting scoliosis.

The effect of a flexible thoracolumbar brace on neuromuscular scoliosis: A prospective observational study.

ABSTRACT: Neuromuscular scoliosis is a common deformity seen in patients with neuromuscular diseases. Although rigid thoracolumbosacral orthosis is the most frequently used brace, it has low compliance rates and can lead to complications including skin ulcers. Thus, alternative methods for treating neuromuscular scoliosis are needed. The purpose of this study is to evaluate the clinical effects of a novel flexible brace to prevent the progression of neuromuscular scoliosis.This study is a prospective observational study. Twenty-three patients with neuromuscular scoliosis were enrolled in the study. Among patients diagnosed with neuromuscular disease, spine radiographs were checked for a neuromuscular scoliosis diagnosis. The participants were treated with a novel flexible brace for 6 months. The control group (n = 46) was selected using propensity score matching method from a clinical data warehouse. The Cobb angle was measured and compared between the study and control groups.In the study group, the average Cobb's angle significantly decreased from 47.22 ±â€Š18.9° to 31.8 ±â€Š20.0 when wearing the flexible brace (P < .001). Thus, the correction rate was 36.9%. The annual progression rate was significantly lower in the study group than in the control group (P  < .05).The flexible brace showed a significant correction rate of scoliosis in patients with severe neuromuscular diseases. The flexible brace is an alternative treatment modality for patients with neuromuscular scoliosis. Daily application of the flexible brace during the growing period can reduce the degree of fixed deformity in the long term.

Compensatory Effects of Sequential 4-Channel Neuromuscular Electrical Stimulation for the Treatment of Acute, Subacute, and Chronic Dysphagia in a Prospective, Double-Blinded Randomized Clinical Trial.

Background. The precise mechanism of 2-channel neuromuscular electrical stimulation (NMES) treatment is unknown, and controversy remains over its efficacy. The sequential 4-channel NMES was newly developed based on normal contractile sequences of swallowing-related muscles. Objective. To assess the clinical efficacy of sequential 4-channel NMES during swallowing. Methods. In this prospective RCT, 52 inpatients with dysphagia (acute, subacute, and chronic state) after stroke, brain tumor, or encephalitis were enrolled. Participants who underwent a videofluoroscopic swallowing study (VFSS) and clinical evaluation were enrolled and were randomly assigned to the 4-channel NMES or sham group. The 4-channel NMES and sham groups swallowed thin and honey-like fluids under NMES (sequential stimulation on suprahyoid and infrahyoid) and sham stimulation, respectively. The procedures were evaluated with the VFSS. Pre- and post-treatment evaluations were performed with the videofluoroscopic dysphagia scale (VDS), penetration-aspiration scale (PAS), Likert scale, and kinematic analysis. Results. The 4-channel NMES group showed significantly greater improvements than the sham group with respect to oral VDS, pharyngeal VDS, total VDS, and PAS (P < .05). Furthermore, the Likert scale for satisfaction, easiness, and discomfort for swallowing showed favorable results for the 4-channel NMES group (P < .05). In the kinematic analysis, the peak speed point, distance, and velocity of hyoid movement were significantly greater in the 4-channel NMES group (P < .05). Conclusions. Sequential 4-channel NMES activating the suprahyoid, thyrohyoid, and other infrahyoid muscles during swallowing showed significant clinical improvement with respect to VDS, PAS, and kinematic analysis. Therefore, sequential 4-channel NMES is a potential new functional electrical stimulation system for the treatment of dysphagia.

Clinical effectiveness of the sequential 4-channel NMES compared with that of the conventional 2-channel NMES for the treatment of dysphagia in a prospective double-blind randomized controlled study.

BACKGROUND: To date, conventional swallowing therapies and 2-channel neuromuscular electrical stimulation (NMES) are standard treatments for dysphagia. The precise mechanism of 2-channel NMES treatment has not been determined, and there are controversies regarding the efficacy of this therapy. The sequential 4-channel NMES was recently developed and its action is based on the normal contractile sequence of swallowing-related muscles. OBJECTIVE: To evaluate and compare the rehabilitative effectiveness of the sequential 4-channel NMES with that of conventional 2-channel NMES. METHODS: In this prospective randomized case-control study, 26 subjects with dysphagia were enrolled. All participants received 2- or 4-channel NMES for 2-3 weeks (minimal session: 7 times, treatment duration: 300-800 min). Twelve subjects in the 4-channel NMES group and eleven subjects in the 2-channel NMES group completed the intervention. Initial and follow-up evaluations were performed using the videofluoroscopic dysphagia scale (VDS), the penetration-aspiration scale (PAS), the MD Anderson dysphagia inventory (MDADI), the functional oral intake scale (FOIS), and the Likert scale. RESULTS: The sequential 4-channel NMES group experienced significant improvement in their VDS (oral, pharyngeal, and total), PAS, FOIS, and MDADI (emotional, functional, and physical subsets) scores, based on their pretreatment data. VDS (oral, pharyngeal, and total) and MDADI (emotional and physical subsets) scores, but not PAS and FOIS scores, significantly improved in the 2-channel NMES group posttreatment. When the two groups were directly compared, the 4-channel NMES group showed significant improvement in oral and total VDS scores. CONCLUSIONS: The sequential 4-channel NMES, through its activation of the suprahyoid and thyrohyoid muscles, and other infrahyoid muscles mimicking physiological activation, may be a new effective treatment for dysphagia.

Efficacy of Modified Cervical and Shoulder Retraction Exercise in Patients With Loss of Cervical Lordosis and Neck Pain.

OBJECTIVE: To explore if the modified cervical and shoulder retraction exercise program restores cervical lordosis and reduces neck pain in patients with loss of cervical lordosis. METHODS: This study was a retrospective analysis of prospectively collected data. Eighty-three patients with loss of cervical lordosis were eligible. The eligible patients were trained to perform the modified cervical and shoulder retraction exercise program by a physiatrist, and were scheduled for a follow-up 6 to 8 weeks later to check the post-exercise pain intensity and lateral radiograph of the cervical spine in a comfortable position. The parameters of cervical alignment (4-line Cobb's angle, posterior tangent method, and sagittal vertical axis) were measured from the lateral radiograph. RESULTS: Forty-seven patients were included. The mean age was 48.29±14.47 years. Cervical alignment and neck pain significantly improved after undergoing the modified cervical and shoulder retraction exercise program (p≤0.001). The upper cervical lordotic angle also significantly improved (p=0.001). In a subgroup analysis, which involved dividing the patients into two age groups (<50 years and ≥50 years), the change of the sagittal vertical axis was significantly greater in the <50 years group (p=0.021). CONCLUSION: The modified cervical and shoulder retraction exercise program tends to improve cervical lordosis and neck pain in patients with loss of cervical lordosis.

Biomechanical influences of gait patterns on knee joint: Kinematic & EMG analysis.

BACKGROUND: As lumbar spinal stenosis commonly occurs between the L2 and L5 segments, hip abductors are easily affected. However, studies regarding the gait pattern in these patients from the coronal plane have not yet been conducted. PURPOSE: To determine the effects of lumbar spinal stenosis on the gait pattern (stride width and femorotibial angle) and hip abductor surface electromyography in varied stride widths compared with healthy individuals. STUDY DESIGN: Prospective case-control study. METHODS: Seventeen patients and 20 healthy individuals were enrolled. Each participant completed three gait assessments in their normal gait, adducted gait and abducted gait. The femorotibial angle and surface electromyography signals were measured. Pain scores was used to quantify the degree of discomfort in the gluteal area and medial side of the knee. RESULTS: When the hip abductors' surface electromyography signals were normalized by quadriceps femoris, patients group showed significantly higher activation ratios throughout all gait patterns. Generally, surface electromyography signals and ratios were significantly higher during abducted gait compared with a normal gait. Femorotibial angle became significantly closer to the varus in healthy individuals during abducted gait. When femorotibial angle during normal gait was compared between the two groups, patients group exhibited slightly wider stride width and FTA significantly closer to the varus. Pain scores were significantly higher in the patient group and during abducted gait. CONCLUSION: Wider stride widths indicated increased relative activation of the hip abductors, closer proximity between femorotibial angle and varus, and increased pain scores for discomfort. The same tendency was observed in patients group when compared with healthy individuals. Widening of stride width in patients group despite abductor weakness suggests that additional muscle recruitment may be needed to maintain balance. Furthermore, such a distinctive gait pattern exerts increased loading on the medial knee, relating to the escalated risk of degenerative knee osteoarthritis.

Application of Automatic Kinematic Analysis Program for the Evaluation of Dysphagia in ALS patients.

Dysphagia in amyotrophic lateral sclerosis (ALS) increases the risk of malnutrition, dehydration, and aspiration pneumonia. Kinematic analysis of videofluoroscopic swallowing study (VFSS) can provide detailed movement of the hyoid bone, revealing abnormalities of swallowing in ALS patients. We developed an automated kinematic analysis program (AKAP) that analyzes the trajectory of the hyoid bone via a visual tracking method. The aim of this study was to investigate the hyoid movement in ALS patients using AKAP and compare it with non-dysphagic subjects. Thirty ALS patients who underwent VFSS in Seoul National University Bundang Hospital between 2015 and 2017 were recruited. For comparison, 30 age-matched control subjects were also enrolled; the same swallowing study was conducted using thin fluid and yogurt. The hyoid bone movement was analyzed by evaluating the vertical and horizontal distances with four peak points (A, B, C, D), and the time of each point were also calculated. With respect to distance parameters, only vertical peak distance (distance between B, D points) during thin fluid swallowing was significantly decreased in ALS patients. (p = 0.038) With respect to temporal parameters, Time ABC, Time ABCD, and Duration C were significantly increased in ALS patients when swallowing both thin fluid and yogurt. (Time ABC p = 0.019, p = 0.002; Time ABCD p = 0.001, p = 0.004; Duration C p = 0.004, p = 0.025 respectively). This result revealed that dysphagia in ALS patient is caused by decreased velocity of hyoid bone movement due to the development of weakness in swallowing-related muscles. The parameters of kinematic analysis could be used to quantitatively evaluate dysphagia in motor neuron disease.

Two novel mutations in TTN of a patient with congenital myopathy: A case report.

BACKGROUND: Early-onset myopathies show a wide spectrum of phenotypes and are composed of various types of inherited neuromuscular diseases, making it difficult to diagnose. TTN mutation-related myopathy is a known cause of early-onset myopathy. Since a next-generation sequencing (NGS) has enabled sequencing of the vast amount of DNA, TTN, which is the longest coding sequence of any human gene, mutations can now be revealed. We report a 10-year-old female with severe congenital muscular weakness and delayed motor development since birth. METHODS: Next-generation sequencing as well as electromyography and muscle biopsy were performed. RESULTS: To date, she is incapable of walking alone. Her younger sister had similar but more severe symptoms with respiratory failure. In electromyography, short-duration, small-amplitude motor unit action potential, and early recruitment patterns were observed in the involved proximal muscles, suggesting myopathy. Muscle histopathology showed a specific atrophy of increased fiber size variability, frequent nuclear internalization, as well as degeneration and regeneration of fibers with type I fiber predominance, consistent with the findings of a previous report about congenital titinopathy. A NGS study revealed two different possible pathogenic variants in TTN: (a) canonical splicing mutation in the intron 105 (c. 29963-1G>C) and (b) frameshift and truncating mutation in the exon 339 (c.92812dup/p.Arg30938LysfsTer15). All variants were confirmed by conventional Sanger sequencing. CONCLUSION: We propose that unbiased genomic sequencing can be helpful in screening patients with early-onset myopathy.

The Mechanism of Hip Dislocation Related to the Use of Abduction Bar and Hip Compression Bandage in Patients With Spastic Cerebral Palsy.

OBJECTIVE: The aims of the study were to identify the differences of forces in the hip adductors between with or without the abduction bar and to evaluate the effect of hip compression bandage on the spasticity of the adductor muscles. DESIGN: Thirty-three patients with cerebral palsy (Gross Motor Functional Classification System IV and V) were prospectively included. Surface electromyography was taken by attaching electromyography on the adductor and abductor muscles. Theraband was used as hip compression bandage. Surface electromyography were taken when spasticity provoked with and without abduction bar, as well as with both abduction bar and hip compression bandage. Root mean square values were measured. RESULTS: Root mean square values were significantly increased with abduction bar in the adductor longus, adductor magnus, and tensor fascia lata muscles. Adductor Sum and Net Adduction Index showed significant increases after the use of abduction bar. After applying hip compression bandage, the Net Adduction Index was significantly decreased. CONCLUSIONS: Our results showed significant changes in the adductor muscles' amplitude, Adduction Sum, and Net Adduction Index. These results indicate that forces that worsen hip dislocation may develop, and therefore, abduction bar should either not be used for spastic cerebral palsy patients or should only be used with hip compression wrapping in place as well.

Rare Concurrence of Congenital Muscular Torticollis and a Malignant Tumor in the Same Sternocleidomastoid Muscle.

While congenital muscular torticollis (CMT) can occur along with other conditions, such as clavicle fracture or brachial plexus injury, these conditions exist outside the sternocleidomastoid muscle (SCM). We present a rare case with concurrence of CMT and a malignant tumor inside the same SCM, along with serial clinical and radiological findings of the atypical features of CMT. The malignant tumor was in fact a low-grade fibromyxoid sarcoma. To the best of our knowledge, the current case is the first of a concurrent condition of CMT inside the SCM. This case suggests that concurrent conditions could exist either inside or outside the SCM with CMT. Therefore, a thorough evaluation of SCM is required when subjects with CMT display atypical features, such as the increase of mass or poor response to conservative therapy. In that case, appropriate imaging modalities, such as ultrasonogram or magnetic resonance imaging, are useful for differential diagnosis.

Reappraisal of Neonatal Greenstick Skull Fractures Caused by Birth Injuries: Comparison of 3-Dimensional Reconstructed Computed Tomography and Simple Skull Radiographs.

OBJECTIVE: The most common birth-associated head injuries during vaginal delivery are cephalhematomas and subgaleal hematomas. Cranial injuries are rarely encountered. The neonate cranium is soft and pliable, and greenstick skull fractures (GSFs) are expected to be more frequent than linear or depressed fractures, but they are extremely difficult to detect with simple skull radiography. As a result, no reports have been issued on this topic to date. Recent reports suggest that technological advances in 3-dimensional (3D) computed tomography (CT) have successfully enhanced the diagnostic accuracy for cranial fractures. The authors researched the types and characteristics of GSFs and the diagnostic accuracy of 3D CT for cranial fractures in neonates. METHODS: The simple skull radiographs and 3D CT images of 101 neonates were retrospectively evaluated and compared with respect to diagnosis of cranial fractures, and skull GSFs were classified on the basis of 3D CT findings into 5 types depending on multiplicity and location. RESULTS: 3D CT detected 88 cases of cranial fractures, that is, 89 GSFs, 4 combined GSFs and linear fractures, and 3 combined GSFs and depressed fractures. The diagnostic rate of 3DCT was 91% and this was significantly higher than the 13% rate of simple skull radiographs (P < 0.001). CONCLUSIONS: GSFs rather than linear fractures were found to account for most cranial injuries among neonates. The diagnostic accuracy of 3D CT was considerably superior than simple skull radiography, but the high radiation exposure levels of 3D CT warrant the need for development of a modality with lower radiation exposure.

A Case of Grisel Syndrome Showing No Underlying Laxity of the Atlanto-axial Joint.

Grisel syndrome is a rare, non-traumatic atlanto-axial subluxation associated with an inflammatory or infectious process in the upper neck. According to the two-hit hypothesis, which is widely accepted for the pathogenesis of Grisel syndrome, preexisting ligamentous laxity of the atlanto-axial joint is regarded as the first hit. An inflammatory or infectious process of the atlanto-axial joint acts as the second hit, resulting in non-traumatic atlanto-axial subluxation. We report on a 6-year-old girl with atlanto-axial subluxation following retropharyngeal and cervical lymphadenitis. She was diagnosed with Grisel syndrome, for which an initial computed tomography did not show any preexisting ligamentous laxity of the atlanto-axial joint. A literature review found only 4 case reports on Grisel syndrome with an initially normal atlanto-axial joint. The present case offers some evidence that a single hit, such as inflammatory changes in the atlanto-axial joint, might cause Grisel syndrome, even without underlying ligamentous laxity.

Effectiveness of Ear Splint Therapy for Ear Deformities.

OBJECTIVE: To present our experience with ear splint therapy for babies with ear deformities, and thereby demonstrate that this therapy is an effective and safe intervention without significant complications. METHODS: This was a retrospective study of 54 babies (35 boys and 19 girls; 80 ears; age ≤3 months) with ear deformities who had received ear splint therapy at the Center for Torticollis, Department of Physical Medicine and Rehabilitation, Ajou University Hospital between December 2014 and February 2016. Before the initiation of ear splint therapy, ear deformities were classified with reference to the standard terminology. We compared the severity of ear deformity before and after ear splint therapy by using the physician's ratings. We also compared the physician's ratings and the caregiver's ratings on completion of ear splint therapy. RESULTS: Among these 54 babies, 41 children (58 ears, 72.5%) completed the ear splint therapy. The mean age at initiation of therapy was 52.91±18.26 days and the treatment duration was 44.27±32.06 days. Satyr ear, forward-facing ear lobe, Darwinian notch, overfolded ear, and cupped ear were the five most common ear deformities. At the completion of therapy, the final physician's ratings of ear deformities were significantly improved compared to the initial ratings (8.28±1.44 vs. 2.51±0.92; p<0.001). There was no significant difference between the physician's ratings and the caregiver's ratings at the completion of ear splint therapy (8.28±1.44 vs. 8.0±1.61; p=0.297). CONCLUSION: We demonstrated that ear splint therapy significantly improved ear deformities in babies, as measured by quantitative rating scales. Ear splint therapy is an effective and safe intervention for babies with ear deformities.
