Lower-limb, powered robotics systems such as exoskeletons and orthoses have emerged as novel robotic interventions to assist or rehabilitate people with walking disabilities. These devices are generally controlled by certain physical maneuvers, for example pressing buttons or shifting body weight. Although effective, these control schemes are not what humans naturally use. The usability and clinical relevance of these robotics systems could be further enhanced by brain-machine interfaces (BMIs). A number of preliminary studies have been published on this topic, but a systematic understanding of the experimental design, tasks, and performance of BMI-exoskeleton systems for restoration of gait is lacking...

PURPOSE: To investigate the levels and factors that influence the abandonment of assistive products by users of a local reference rehabilitation center. METHODS: This observational study involved users who received services and assistive products provided by our center of rehabilitation. Users were identified using the records of the center and their responses about the abandonment were collected through face-to-face interviews. RESULTS: The abandonment level of assistive products was 19...

INTRODUCTION: It has been widely postulated that structural and functional misalignments of the foot, such as flat foot, may cause mechanical deviations of the lower limb during walking. The aim of this study was to investigate the effect of foot orthoses on lower extremity joint moment asymmetry during the stance phase of walking in children with asymptomatic flexible flat feet. METHODS: Fourteen volunteer male children, clinically diagnosed with flexible flat feet, participated in this study...

INTRODUCTION: The most common surgical treatment of traumatic spine fractures is through a posterior approach using pedicle screws and rods. Postoperative treatment protocols including the use of postoperative orthoses however differ between hospitals and surgeons. A three-point hyperextension orthosis is designed to support proper posture and unload the anterior column. Some motion remains when wearing an orthosis, and its main value in postoperative treatment is therefore believed to be pain relief and patient confidence...

BACKGROUND: Customized foot orthoses (CFO) have been widely accepted to reduce the frequency of foot problems and postural disorders. The purpose of the research was to compare the influence of CFO utilization on the venous status among healthy females and males. METHODS: This was a quasi-experimental study (NCT03329430), which included 20 healthy subjects that completed all the stages of the process. The subjects showed an age mean of 20.00 ± 1.62 years and were recruited in a foot and ankle specialist center...

Understanding balance during human gait is complicated by the abundance of recovery options. Among all possible recovery options, three main strategies are often considered for human balance control, being the ankle, hip, and foot placement strategies. All can be addressed when balance is threatened during walking, but their relative importance remains uncertain. We have previously shown that healthy human subjects did not significantly adjust their foot placement relative to the body's center of mass (COM) in the first recovery step following anteroposterior pelvis perturbations, as compared to unperturbed walking...

BACKGROUND: Foot drop in people with multiple sclerosis (pwMS) often managed with assistive technologies, such as functional electrical stimulation and ankle foot orthoses. No evidence synthesis exists for the psychometric properties of outcomes used to evaluate the efficacy of these interventions. OBJECTIVE: This systematic review aimed to identify the outcome measures reported to assess the benefits of assistive technology for pwMS and then synthesize the psychometric evidence in pwMS for a subset of these measures...

STUDY DESIGN: Systematic review INTRODUCTION: Trigger finger (TF) is a common condition in the hand. The primary purpose of this systematic review was to evaluate the current evidence to determine the efficacy of orthotic management of TF. A secondary purpose was to identify the characteristics of the orthotic management. The tertiary purpose of this study was to ascertain if the studies used a patient-reported outcome to assess gains from the patient's perspective. METHODS: All studies including randomized controlled trials, prospective, and retrospective cohort studies were included in this review due to limited high-level evidence...

In the rehabilitation field, the use of additive manufacturing techniques to realize customized orthoses is increasingly widespread. Obtaining a 3D model for the 3D printing phase can be done following different methodologies. We consider the creation of personalized upper limb orthoses, also including fingers, starting from the acquisition of the hand geometry through accurate 3D scanning. However, hand scanning procedure presents differences between healthy subjects and patients affected by pathologies that compromise upper limb functionality...

BACKGROUND: The proposed association between osteofibrous dysplasia and adamantinoma has led some to advocate resection of the entire lesion, which can require major subsequent reconstruction. However, this link remains unproven and there is some support in more recent literature for a less aggressive approach. This study aims to describe our experience managing pediatric tibial osteofibrous dysplasia with such an approach and to report functional outcomes in children treated thus. METHODS: A total of 28 cases of osteofibrous dysplasia in 25 patients were managed at a referral center for pediatric bone tumors with observation in the first instance, then limited surgical intervention if required to address pain and deformity...

BACKGROUND Knee osteoarthritis (KOA) is a common disease that can change the load on lower limbs during walking. Plantar loads in patients with KOA may provide a basis for clinical decisions regarding footwear and foot orthoses. This study aimed to compare plantar loads in females with and without KOA during gait. MATERIAL AND METHODS Plantar pressure during walking was recorded in 23 females with KOA and 23 females without KOA. Maximum force (MF), contact area (CA), and peak pressure (PP) were measured at 7 different regions underneath the foot, named heel (M1), midfoot (M2), first metatarsophalangeal joint (MPJ) (M3), second MPJ (M4), third to fifth MPJ (M5), hallux (M6), and lesser toes (M7)...
