Cerebral palsy (CP) is the most common childhood motor disability and often results in debilitating walking abnormalities, such as flexed-knee and stiff-knee gait. Current medical and surgical treatments are only partially effective in improving gait abnormalities and may cause significant muscle weakness. However, emerging artificial walking technologies, such as step-initiated, multichannel neuromuscular electrical stimulation (NMES), can substantially improve gait patterns and promote muscle strength in children with spastic CP...

BACKGROUND: Posterior tibial tendinopathy is a challenging foot condition resulting in pes planus, which is difficult to diagnose in the early stage. Prior to the deformity, abnormal internal load transfer and soft tissue attenuation are anticipated. The objective of this study was to investigate the internal load transfer and strain of the ligaments with posterior tibial tendinopathy, and the implications to pes planus and other deformities. METHODS: A three-dimensional finite element model of the foot and ankle was reconstructed from magnetic resonance images of a 28-year-old normal female...

BACKGROUND: Initial micromotion of a total hip replacement is associated with aseptic loosening. The use of bisphosphonates could be one way to reduce peri-implant bone resorption induced by micromotion. Bisphosphonates compounds are inhibitors of bone resorption. The aim of this study was to investigate whether local treatment with bisphosphonate would reduce bone resorption and fibrous tissue around an experimental implant subjected to micromotion. METHODS: One micromotion implant were inserted into each medial femoral condyle in ten sheep...

Inhibition is known to influence balance, step initiation and gait control. A specific subcomponent of inhibition, the perceptual inhibition process, has been suggested to be specifically involved in the integration of proprioceptive information that is necessary for efficient postural responses. This study aimed to investigate the inhibition requirements of planning and executing a choice step initiation task in young adults following experimental perturbation of proprioceptive information using Achilles tendon vibrations...

A 22-year-old man was referred for orthopedic follow-up after an ankle injury. Initial evaluation in urgent care included radiographs with negative findings. After a delayed presentation, a course of functional treatment was recommended. Subsequently, he developed a deep venous thrombosis and pulmonary emboli. He was found to be factor V Leiden deficient and was fully anticoagulated on warfarin. Later reevaluation revealed a steppage gait and foot drop. Electrodiagnostic studies (ie, electromyography and nerve conduction studies) revealed a severe peripheral polyneuropathy...

As recreational running continues to gain popularity, more individuals are seeking ways to improve running performance. RunSmart is a running intervention program designed to enhance a runner's form. In addition to correcting flaws in a runner's form, RunSmart offers the opportunity for runners to continue a regular regimen while slowly integrating changes in form. The purpose of this case series was twofold: to determine if the RunSmart program coincides with improvements in oxygen consumption (VO2), a variable often associated with better running performance times, and to evaluate the RunSmart program in regard to enhancing gait biomechanics...

We report the clinical and electrophysiological findings in seven patients with orthostatic myoclonus (OM) associated with gait initiation failure and falls. OM is one of the causes of unsteadiness of stance and gait, and it may develop as a symptom of neurodegenerative disorders. Both positive myoclonic bursts and negative myoclonus may be seen in electrophysiological recordings, and electrophysiological analysis suggests a subcortical origin for OM.

Plantar fasciopathy (PF) is the most common cause of heel pain. Extracorporeal shockwave therapy (ESWT) improves the gait pattern in patients with PF. However, the effects of ESWT on the biomechanics of the ankle in these patients remains unclear. Sixteen participants were included in the present study. Of the 16 participants, 8 patients with PF were assigned to receive extracorporeal shockwave therapy, and 8 healthy participants served as an external control group. ESWT was applied to the PF group for 1500 pulses at an energy flux of 0...

Dropped head syndrome (DHS) is a cervical kyphotic deformity caused by apparent weakness of the neck extensor muscles. We often encounter patients whose symptoms, including impaired forward vision and neck pain, deteriorate while walking. This is the first report of a case of dynamic spinal alignment change in a patient with DHS during walking using three-dimensional gait analysis. A 78-year-old Japanese woman complained of impaired forward vision and neck pain while walking. Her radiograph showed severe cervical kyphosis...

Hip implants subject to gait loading due to occupational activities are potentially prone to failures such as osteolysis and aseptic loosening, causing painful revision surgeries. Highly risky gait activities such as carrying a load, stairs up or down and ladder up or down may cause excessive loading at the hip joint, resulting in generation of wear and related debris. Estimation of wear under the above gait activities is thus crucial to design and develop a new and improved implant component. With this motivation, this paper presents an assessment of wear generation of PCD-on-PCD (poly crystalline diamond) hip implants using finite element (FE) analysis...

This study examined how gait bradykinesia is changed by the motor programming in Parkinson's disease. Thirty-five idiopathic Parkinson's disease patients and nine age-matched healthy subjects participated in this study. After the patients fixated on a visual-fixation target (conditioning-stimulus), the voluntary-gait was triggered by a visual on-stimulus. While the subject walked on a level floor, soleus, tibialis anterior EMG latencies, and the y-axis-vector of the sole-floor reaction force were examined. Three paradigms were used to distinguish between the off-/on-latencies...

We proposed a new ankle-foot orthosis using elastomer-embedded flexible joints (EEFJ), composed of C-shaped springs and 3D-printed circular elastomer. This orthosis was designed to reduce burden on the tibialis anterior muscle (TA) and to achieve clearance between the tip of the toe and the ground. Strength testing, and gait analysis were conducted for the orthosis. According to the results of strength testing, the combination of the C-spring with 0.3 mm and 0.5 mm thickness and the elastomer with 30% and 60% filling density performs a supporting torque of 0...
