Background: The prognosis of surgically treated subjects with early onset scoliosis (EOS) into adulthood has been lacking. We aimed to investigate the patients' perspectives on satisfaction with surgical treatment.

Methodology: We included all surgical candidates with EOS who had undergone index spinal surgery for scoliosis correction between 2009 and 2013.

Background: Although back pain may be present in subjects with adolescent idiopathic scoliosis (AIS), its natural history is unknown. Therefore, this study evaluated the incidence of back pain in scoliotic adolescents longitudinally.

Methods: This retrospective analysis examined prospectively collected pain subscale data of the Scoliosis Research Society questionnaire between the initial presentation and up to 3 years of follow-up.

Background: Back pain occurs commonly in adults and is multifactorial in nature. This study aimed to assess the prevalence and intensity of back pain during young adulthood in subjects with adolescent idiopathic scoliosis (AIS), as well as factors that may be associated with its prognosis.

Methods: Subjects with AIS aged 20-39 treated conservatively were included in this study.

Since idiopathic scoliosis is a multifactorial disorder, the proprioceptive defect is considered one of its etiological factors. Genetic studies have separately revealed this relationship, yet it remains indeterminate which specific genes that related to proprioception contributed to the initiation, progression, pathology, and treatment outcomes of the curvature. A systematic search was conducted on four online databases, including PubMed, Web of Science, Embase, and Academic search complete.

Purpose: This review aimed to identify effective physical performance tests (PPT) as clinical outcome indicators for detecting and monitoring degenerative cervical myelopathy (DCM).

Methods: A comprehensive literature search was performed on seven electronic databases on the effectiveness in detection and monitoring of DCM by PPT. All included studies were reviewed and undergone quality assessments on the risk-of-bias by Newcastle-Ottawa Scale and were pooled by random-effect analysis with level of significance at 0.

Purpose: Although it is evident that some patients with adolescent idiopathic scoliosis (AIS) have proprioceptive deficit in peripheral joints, knowledge on the proprioceptive function of the deformed spine is limited. Nonetheless, spinal proprioception in AIS may be affected three-dimensionally, prior studies only focussed on evaluating peripheral proprioception in single plane. Therefore, this study aimed to develop a novel spinal proprioception assessment using three-dimensional motion analysis in patients with AIS.

Study Design: Systematic review and meta-analysis.

Objectives: The present review aimed to summarize the evidence regarding differences in proprioception between children with and without adolescent idiopathic scoliosis (AIS).

Methods: Seven electronic databases were searched from their inception to April 10, 2021.

Purpose: Oswestry Disability Index (ODI) was established by Fairbank in 1989 to assess functional disabilities in low back pain (LBP). It was last updated in 2019 as ODI version 2.1b (ODI AU_2.

Background: Cervical collars are used after laminoplasty to protect the hinge opening, reduce risks of hinge fractures, and avoid spring-back phenomena. However, their use may lead to reduced range of motion and worse neck pain.

Objective: To investigate the clinical, radiological, and functional outcomes of patients undergoing single-door laminoplasty with or without collar immobilization.

Purpose: To examine the effectiveness of a multidisciplinary rehabilitation programme for patients with chronic low back pain in Hong Kong, and to identify factors associated with work resumption.

Methods: 57 men and 8 women aged 20 to 56 (mean, 39) years who had a more than 3-month history of low back pain and were unresponsive to more than 6 months of conventional treatment participated in a 14-week multidisciplinary rehabilitation programme involving physical conditioning, work conditioning, and work readiness. Training protocols entailed flexibility and endurance training, hydrotherapy, weight lifting, and work stimulation.

Article Synopsis
  • A study was conducted with 30 cerebral palsy patients to evaluate the relationship between upper limb deformity, spasticity, motor control, sensation, and hand function.
  • Results showed that increased deformity and spasticity led to greater functional deficits in hand use, with tetraplegic patients being the most affected.
  • The Melbourne Assessment of the Unilateral Upper Limb Function Test (MAULF) and Functional Hand Grip Test (FHGT) were more effective than the Functional Independence Measure (WeeFIM) in assessing hand function in these patients.

Limb lengthening aims to reduce limb length discrepancy, improve cosmesis, and permit more functional mobility. Scarring, however, is a major concern of patients. In this study 25 patients (27 lengthening sites) were assessed; 6 sites were lengthened with Orthofix and 21 sites with Ilizarov.
