About the Lab

Professor Dongwook Na's research lab specializes in pediatric rehabilitation and neuromuscular disorders, with a primary focus on improving motor function and quality of life in children with cerebral palsy. The lab investigates innovative, non-invasive interventions such as hippotherapy, botulinum toxin A (BTX-A) injections, and orthotic devices like ankle-foot orthoses (AFOs), often combining them with serial casting or ultrasound-guided assessments. A key emphasis is placed on objective measurement of muscle architecture, postural control, and functional outcomes using advanced imaging and biomechanical tools. The lab also develops and validates culturally adapted patient-reported outcome measures, such as the Quality of Communication Life Scale, to support individualized therapy and rehabilitation planning.

http://kmbase.medric.or.kr/Main.aspx?d=KMBASE&m=VIEW&i=0311120100510040579

Purpose: The purpose of this paper is to test the hypothesis that combination therapy of serial cast and botulinum toxin type A (BTX-A) injection can further enhance the effects of a BTX-A injection in ambulant children with cerebral palsy (CP)who have an equinus foot. Materials and Methods: Children in group A (30 legs of 21 children) received a serial casting application after an injection of BTX-A,and children in group B (25 legs of 17 children) received only a BTX-A injection. Assessments we

‘ASHA 의사소통 삶의 질 척도’의 한국어판 번안: 청소년용
최혜윤, 김용욱, 나동욱, 김향희

배경 및 목적: 의사소통능력은 심리사회적 적응 및 타인과의 상호작용에 필수적이다. 본 연구에서는 의사소통 삶의 질 척도(Quality of Communication Life Scale: QCL, 이하 QCL)를 우리말로 번안하고 신뢰도와 타당도를 검증하고자 청각장애 및 정상청력 청소년에게 시행하였다. 방법: 대상자로는 언어치료를 받고 있거나 농학교에 재학 중인 만 13~18세의 청각장애 청소년 90명, 그리고 이들과 성별 및 연령을 일치시킨 정상청력 청소년 180명을 포함하였다. QCL과 PedsQL을 실시한 후 비교하고, 문항 내적일관성과 검사-재검사 신뢰도, 내용타당도, 대면타당도, 공인타당도 및 내적 구성타당도를 산출하였다. 결과: 두 집단 사이에 의사소통 관련 삶의 질의 유의한 차이가 있었다. 또한 QCL은 높은 문항 내적일관성 신뢰도를 지니고 있으며, 의사소통 관련 삶의 질을 측정하는데 높은 타당도를 보여 의사소통 관련 삶의 질 평가도구로서 매우 유용한 도구임을 알 수 있었

Purpose: This study used ultrasonography (US) to investigate the architectural changes in gastrocnemius muscles (GCM) after botulinum toxin injection (BoNT-A) in children with cerebral palsy (CP). Materials and Methods: Thirteen childrenwith CP who received a BoNT-A injection into their GCM to treat equinus were recruited (9 males and 4 females). Architectural changes in both the medial and lateral heads of the GCM from a total of 20 legs were assessed using B-mode, real-time US. Muscle thicknes

Comparison of the Ratio of Upper to Lower Chest Wall in Children with Spastic Quadriplegic Cerebral Palsy and Normally Developed Children
박은숙, 박정현, 나동욱, 박창일, 박찬우
http://kmbase.medric.or.kr/Main.aspx?d=KMBASE&m=VIEW&i=0311120060470020237

The upper chest wall does not grow properly in children with spinal muscular atrophy (SMA) with paradoxical breathing. This suggests that long-term inability to take a deep breath in developing children may result in underdevelopment of the upper chest wall. In addition, a rapid and paradoxical breathing pattern is frequently observed in children with severe cerebral palsy (CP), which often corresponds to the underdevelopment of the upper chest wall. The present study is designed to evaluate the

Purpose: This study aimed to investigate useful parameters for estimating gastrocnemius(GCM) muscle volume (MV) using ultrasonography (US) and anthropometryin children with spastic cerebral palsy (CP). Materials and Methods: Eighteenlegs from nine children with spastic CP aged 2 to 6 years were investigated in this study. Tibial length (TL) of each leg was measured and muscle thickness (MT) and anatomical cross-sectional area (aCSA) of GCM muscles were assessed using US. The volume of the GCM wa

박창일, 박은숙, 김현우, 나동욱
http://kmbase.medric.or.kr/Main.aspx?d=KMBASE&m=VIEW&i=0311120060470050657

The purpose of this study was to evaluate how soft tissue surgery for correcting equinus deformity affects the kinematic and kinetic parameters of the ankle and proximal joints. Sixteen children with spastic hemiplegic cerebral palsy and equinus deformities (age range 3-16 years) were included. Soft tissue surgeries were performed exclusively on the ankle joint area in all subjects. Using computerized gait analysis (Vicon 370 Motion Analysis System), the kinematic and kinetic parameters during b

The Effect of Obturator Nerve Block on Hip Lateralization in Low Functioning Children with Spastic Cerebral Palsy
박은숙, 심은결, 나동욱, 이원철

Purpose: Hip adductor spasticity has a great impact on developing hip displacement in children with cerebral palsy (CP). Obturator nerve (ON) block is less invasive intervention rather than soft tissue surgery for reduction of hip adductor spasticity. The aim of this study is to investigate the effect of ON block on hip lateralization in low functioning children with spastic CP. Materials and Methods: The study was performed by retrospective investigation of the clinical and radiographic follow-
