Strategies for unplanned gait termination at comfortable and fast walking speeds in children with cerebral palsy.

Collision avoidance while walking is necessary for safe living, and faster walking speeds tend to increase collision risk. However, gait termination strategies for patients with cerebral palsy (CP), from comfortable to faster speed, remain unexplored. This study aimed to analyze these strategies in children with CP compared to typically developing (TD) children at two different speeds.

Gait velocity control using projection mapping for children with spastic diplegia cerebral palsy.

Background: Gait characteristics in children with cerebral palsy vary according to their individual walking speed. As such, establishing methods to maintain a consistent gait velocity are necessary to evaluate specific intervention effects in this clinical population. Our study aim was to validate the accuracy of projection mapping for guiding gait velocity to a control gait velocity.

Identification of small-sized intrachromosomal segments at the ends of INV-DUP-DEL patterns.

The mechanism of chromosomal rearrangement associated with inverted-duplication-deletion (INV-DUP-DEL) pattern formation has been investigated by many researchers, and several possible mechanisms have been proposed. Currently, fold-back and subsequent dicentric chromosome formation has been established as non-recurrent INV-DUP-DEL pattern formation mechanisms. In the present study, we analyzed the breakpoint junctions of INV-DUP-DEL patterns in five patients using long-read whole-genome sequencing and detected 2.

Earlier appearance of Risser sign on ultrasound versus radiograph in adolescent idiopathic scoliosis.

Objective: The usefulness of ultrasound in the detailed assessment of the Risser sign is still unclear. The purpose of this study was to analyze the usefulness of ultrasound for determining the Risser sign compared with that determined by conventional radiography by each Risser grade.

Materials And Methods: Eighty-eight iliac crests from 44 adolescent patients who visited the scoliosis clinic with Risser grades 0-4 were evaluated.

Degenerative Lumbar Spondylolisthesis Patients With Movement-related Low Back Pain Have Less Postoperative Satisfaction After Decompression Alone.

Study Design: Retrospective analysis of prospectively collected multicenter observational data.

Objective: The aim was to examine the preoperative factors affecting postoperative satisfaction following posterior lumbar interbody fusion (PLIF) and microendoscopic muscle-preserving interlaminar decompression (ME-MILD) in patients with degenerative lumbar spondylolisthesis (DLS).

Summary Of Background Data: The technique involved in DLS surgery may either be decompression alone or decompression-fixation.

Chronic atlantoaxial rotatory fixation with neurofibromatosis type I: A case report.

Background: Atlantoaxial rotatory fixation (AARF) can be caused by infection, rheumatoid arthritis, surgery of head and neck, and congenital diseases. Type 1 neurofibromatosis (NF-1) is often associated with various musculoskeletal diseases, but few reports have described AARF with NF-1. Here, we report the success of a closed reduction and halo fixation utilized to treat chronic AARF with NF-1 in a 7-year-old female.

Analysis of center of mass and center of pressure displacement in the transverse plane during gait termination in children with cerebral palsy.

Background: While gait termination is challenging for children with spastic cerebral palsy (CCP), few studies have quantitatively assessed this issue.

Research Question: What are the characteristics of center of mass (COM) and center of pressure (COP) displacement during gait termination in CCP, and how do they compare with those in children with typical development (CTD)?

Methods: This cross-sectional study included 13 adults with typical development (19.85 ± 0.

Pediatric spinal infection with epidural abscess: A report of two cases.

Background: Pediatric spinal infections are rare and often accompanied by abscesses. Delayed diagnosis commonly leads to a poor neurological prognosis, emphasizing the need for early diagnosis and treatment.

Case Description: We report on two cases of spinal infection; one in a 5-year-old boy with a T8-11 epidural abscess and one in a 10-year-old boy with an L5-S1 epidural abscess.

Growing Rod Surgery for Early-Onset Scoliosis in an Osteogenesis Imperfecta Patient.

Background: Osteogenesis imperfecta (OI) is characterized by bone fragility and is often accompanied by spinal deformity. Surgical treatment for early-onset scoliosis in patients with OI is hazardous and difficult due to the bone fragility and rigidity of the deformity. A case of early-onset scoliosis with OI that was treated using growing-rod surgery is presented.

Alignment of the rearfoot and foot pressure patterns of individuals with medial tibial stress syndrome: A cross-sectional study.

Objective: To compare the rearfoot alignment (leg-heel angle, LHA) during standing and walking, and foot pressure during walking between individuals with medial tibial stress syndrome (MTSS) and asymptomatic individuals participating in daily sports.

Design: A cross-sectional study.

Setting: Research laboratory.

Relationship between walking efficiency and muscular strength of the lower limbs in children with cerebral palsy.

[Purpose] In children with cerebral palsy, despite increases in muscle strength after strengthening, improvements in walking efficiency are inconsistent in previous studies. The purpose of this study was to analyze the relationship between walking efficiency and muscle strength in children with cerebral palsy. [Participants and Methods] Twenty-six children with cerebral palsy participated in this study.

Surgical Treatment for Severe Scoliosis in Patients with Reduced Cardiorespiratory Function after Surgery for Congenital Heart Disease: A Report of Two Cases.

Purpose: Congenital heart disease (CHD) is associated with an increased risk of scoliosis. The prognosis of scoliosis patients with CHD has improved because of advances in cardiac care. As a result, the frequency of surgery for scoliosis in this population has increased, although the risk of perioperative complications remains high.
