Effective factors on brace compliance in idiopathic scoliosis: a literature review.

Objectives: Compliance plays a major role in the success of brace treatment and is influenced by factors such as the kind of brace, measurements method, regimen for brace wear, pattern wearing at night/day or full/part time and another factor is also psychological condition of the wearer. The objective of this review is to assess affecting factors on compliance of spinal braces in idiopathic scoliosis.Materials and methods: The guideline of the Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) was used for conducting review and assessing the quality of evidence. The search in Pubmed databases had 175 results of which 17 articles met the inclusion criteria. Effective factors on compliance were extracted and categorized into six groups based on type of brace, measurement method, age, day/night time pattern wearing, full/part time wearing and psychological aspect that can improve the result of spinal brace treatment in idiopathic scoliosis.Results: The results demonstrated that the type of braces determines structure and appearance and affects compliance. Psychological aspects, age, brace wear pattern (daytime or nighttime or part-time versus fulltime) and the assessment method (using temperature versus pressure sensors) can affect recorded compliance.Conclusions: Compliance can be augmented by considering factors in the design and delivery of the brace. Superior appearance and comfortable within the brace can improve psychological acceptance and improve the compliance. Lower age, involving the patient in treatment procedure, considering the child habits, and improved family awareness of the treatment plan of idiopathic scoliosis can also improve overall compliance of the brace.Implications for rehabilitationThis article reviews factors that affect compliance with orthotic treatment in idiopathic scoiliosis.

Sensory feedback add-on for upper-limb prostheses.

BACKGROUND AND AIM: Sensory feedback systems have been of great interest in upper-limb prosthetics. Despite tremendous research, there are no commercial modality-matched feedback systems. This article aims to introduce the first detachable and feedback add-on option that can be attached to in-use prostheses. TECHNIQUE: A sensory feedback system was tested on a below-elbow myoelectric prosthesis. The aim was to have the amputee grasp fragile objects without crushing while other accidental feedback sources were blocked. DISCUSSION: A total of 8 successful trials (out of 10) showed that sensory feedback system decreased the amputee's visual dependency by improving awareness of his prosthesis. Sensory feedback system can be used either as post-fabrication (prosthetic add-on option) or para-fabrication (incorporated into prosthetic design). The use of these direct feedback systems can be explored with a current prosthesis before ordering new high-tech prosthesis. Clinical relevance This technical note introduces the first attach/detach-able sensory feedback system that can simply be added to in-use (myo)electric prosthesis, with no obligation to change prosthesis design or components.

Patellar tendon bearing brace: combined effect of heel clearance and ankle status on foot plantar pressure.

BACKGROUND: Heel clearance and ankle status (free or locked) are of major determinants affecting peak plantar pressures and contact area in patellar tendon bearing brace and have been separately studied by many researchers. This study investigated the combined effect of ankle status and heel clearance on contact area and peak plantar pressure in different areas of foot (hindfoot, midfoot, and forefoot). STUDY DESIGN: Before-after repeated measurement trial. METHODS: Nine healthy male volunteers walked 8 m with normal shoe and four conditions of patellar tendon bearing brace wear. Repeated-measure analysis of variance test was used to compare contact area and plantar pressure changes in three areas of the foot. RESULTS: Application of patellar tendon bearing brace significantly reduced overall plantar pressure and contact area (p < 0.01). Although both contact area and plantar pressure significantly decreased in hindfoot and midfoot, plantar pressure increased in forefoot area (p < 0.05). CONCLUSIONS: Application of the patellar tendon bearing brace can reduce the overall peak plantar pressure in the foot but increases focal plantar pressure in forefoot. Excessive lifting of the heel seems to minimize the contact area, thus increase focal pressure in forefoot. Overall, plantar pressure seems to be more effectively off-loaded by combining maximum heel clearance and restriction of the ankle joint. CLINICAL RELEVANCE: Although effective parameters of patellar tendon bearing brace have been separately addressed in previous studies, no study was found that investigated the combined effect of ankle status and heel clearance. This study investigates the combined effect of these parameters and provides detailed information on clinical application of the patellar tendon bearing brace.
