BACKGROUND: Subjects with Spinal Cord Injury (SCI) should use various assistive devices to stand and walk. Unfortunately they suffer from slow walking speed, high energy consumption, and too much force applied on upper limb while walking. The aim of this study was to determine the gap between the gait performance of SCI and normal subjects to conclude how the performance of SCI can be improved. METHOD: Three groups of SCI walked with orthosis, SCI walked without orthosis, and normal subjects were recruited in this study...

Scar contracture deformity, which can lead to dysfunction of hand and low quality of life, is one of the common complication after hand burns. The prevention measures of scar contracture after hand burns include large skin grafting, prevention of infection, insistence on wearing pressure gloves, use of silicone sheets, wearing orthosis, accepting proper physical therapy, and early functional exercise. The primary treatments of postburn contractures of the hand are surgery, drugs, laser treatment, and rehabilitation therapy...

: Non-union of forearm bone shaft fractures remains, in some cases, a major clinical problem. The aim of this study was to assess the biomechanical causes of non-union in a patient with diaphyseal forearm fractures fixated with LCP plates. The paper describes the case of a 35-year-old male who developed a non-union as a result of destabilisation of the fixation. The case was analysed with an in silico analysis of the removed fixation device. CONCLUSION: To sum up, we believe that the case described in this paper confirms the limitations to the use of LCP reconstruction plates in patients with well-developed musculature, even in the case of repeat fixation, when good adjustment of the plate well to the axis of the bone appears necessary...

INTRODUCTION: Ruptures of the Achilles tendon are the most common tendon injuries of the lower extremities. Besides the initial operative or non-operative treatment, rehabilitation of patients plays a crucial role for tendon healing and long-term outcome. As only limited evidence is available for optimized rehabilitation regimen and guidelines for the initial (e.g., first 6 weeks) rehabilitation are limited, this study investigated the current rehabilitation concepts after Achilles tendon rupture...

Osteogenesis imperfecta is an inherited disorder of the connective tissue characterized primarily by fractures with no or small causal antecedents and extremely variable clinical presentation. The disorder requires a global and, therefore, multidisciplinary therapeutic approach that should aim, among other aspects, at the prevention and treatment of deformities resulting from osteogenesis imperfecta. Due to limitations related to bony deformities, it can be difficult to place these infants in a variety of positions that would help remediate skull deformities, so a cranial orthosis becomes the therapy of choice...

Cerebral Palsy (CP) is the leading cause of childhood motor disability, with a global incidence of 1.6 to 2.5/1,000 live births. Approximately 23% of children with CP are dependent upon assistive technologies. Some children with developmental disabilities have self-injurious behaviors such as finger biting but also have therapeutic needs. The purpose of this technical note is to describe design considerations for a protective glove and finger covering that maintains finger dexterity for children who exhibit finger and hand chewing (dermatophagia) and require therapeutic range of motion and may benefit from sensory stimulation resulting from constant contact between glove and skin...

PURPOSE: Among patients who undergo surgical treatment of terrible triad elbow injuries (TTEI), we hypothesized that those who received perioperative glucocorticoid (GC) therapy would have improved postoperative pain and range of motion (ROM) and a similar complication rate compared with patients who did not receive GC therapy. METHODS: We retrospectively identified 26 patients who underwent surgical treatment of TTEI from 2009 to 2015. Thirteen patients received a single intraoperative dose of 10 mg intravenous dexamethasone followed with a 6-day oral methylprednisolone taper course (GC group), and 13 did not (control group)...

We present the case of two patients aged 12 years and 7 years who were referred to our hospital for factor VII deficiency inherited in an autosomal recessive pattern, who had suffered from previous multiple joint haemarthroses. They presented with fine motor symptoms and difficulty in walking. During physical examination we observed neurological symptoms (general hypotonia, muscular hypotrophy, exaggerated tendon reflexes, pes cavus, and spastic gait). Given that the symptoms were not justified by the deficiency of coagulation factor VII and on suspicion of hereditary spastic paraplegia (HSP), tests were carried out...

BACKGROUND: In the development of efficacious driven gait orthoses (DGO), it is an added value to consider patients' and therapists' perspectives concerning robot-assisted gait training (RAGT). A better understanding of these issues may improve the process of care and outcome. OBJECTIVES: This study aimed to examine stroke patients' motivation and expectations of RAGT, and therapists' expectations and perspectives on the usability of RAGT. Additionally, the differences in expectations between stroke patients and their therapists were analyzed...

INTRODUCTION: Neurologic paralysis of the foot due to damage to the central nervous system is primarily caused by a cerebral insult. The ankle-foot orthosis (AFO), which is the classical conservative treatment option, is associated with drawbacks, e.g., increased contractures, limited mobilization from the sitting position, and cosmetic aspects. METHODS: Functional external electrostimulation (FES) is an suitable treatment method for patients with a central lesion and intact peroneal nerve...

BACKGROUND: Wearing lumbosacral orthosis (LSO) is one of the most common treatments prescribed for conservative management of low back pain. While the results of randomized controlled trials suggest effectiveness of LSO in reducing pain and disability in these patients, there is a concern that prolonged use of LSO may lead to trunk muscle weakness and atrophy. PURPOSE: The present review aimed to evaluate available evidence in literature to determine whether LSO result in trunk muscle weakness and/or atrophy...

Musculoskeletal modeling and simulation techniques have been used to gain insights into movement disabilities for many populations, such as ambulatory children with cerebral palsy (CP). The individuals who can benefit from these techniques are often limited to those who can walk without assistive devices, due to challenges in accurately modeling these devices. Specifically, many children with CP require the use of ankle-foot orthoses (AFOs) to improve their walking ability, and modeling these devices is important to understand their role in walking mechanics...

The femoral head in subjects with leg calve perthes disease (LCPD) is generally considerably deformed. It is debatable whether this deformation is due to an increase in applied loads, a decrease in bone mineral density or a change in containment of articular surfaces. The aim of this study was to determine the influence of these factors on deformation of the femoral head. Two subjects with LCPD participated in this study. Subject motion and the forces applied on the affected leg were recorded using a motion analysis system (Qualsis(TM)) and a Kistler force plate...

BACKGROUND: Unlike in healthy controls, sensorimotor β-desynchronization (β-ERD) is compromised in stroke patients, i.e., the more severe the patient's motor impairment, the less β-ERD. This, in turn, provides a target substrate for therapeutic brain self-regulation and neurofeedback. OBJECTIVE: Transcranial alternating current stimulation (tACS) has been shown to modulate brain oscillations during and after stimulation, and may thus facilitate brain self-regulation during neurofeedback interventions...

[Purpose] Standing and walking are impaired in stroke patients. Therefore, assisted devices are required to restore their walking abilities. The ankle foot orthosis with an external powered source is a new type of orthosis. The aim of this study was to evaluate the performance of a powered ankle foot orthosis compared with unpowered orthoses in a stroke patient. [Subjects and Methods] A single stroke subject participated in this study. The subject was fitted with three types of ankle foot orthosis (powered, posterior leg spring, and carbon ankle foot orthoses)...
