BACKGROUND: Arthrodesis of the first metatarsophalangeal (MTP1) joint is an intervention often used in patients with severe MTP1 joint osteoarthritis and relieves pain in approximately 80% of these patients. The kinematic effects and compensatory mechanism of the foot for restoring a more normal gait pattern after this intervention are unknown. The aim of this study was to clarify this compensatory mechanism, in which it was hypothesized that the hindfoot and forefoot would be responsible for compensation after an arthrodesis of the MTP1 joint...

The human ankle joint plays a critical role during walking and understanding the biomechanical factors that govern ankle behavior and provides fundamental insight into normal and pathologically altered gait. Previous researchers have comprehensively studied ankle joint kinetics and kinematics during many biomechanical tasks, including locomotion; however, only recently have researchers been able to quantify how the mechanical impedance of the ankle varies during walking. The mechanical impedance describes the dynamic relationship between the joint position and the joint torque during perturbation, and is often represented in terms of stiffness, damping, and inertia...

PURPOSE OF REVIEW: Spinocerebellar ataxia type 12 (SCA12) is a rare autosomal dominant neurodegenerative disease characterized by tremor, gait abnormalities, and neuropsychiatric syndromes. The location of the causative CAG/CTG expansion mutation in PPP2R2B, a gene encoding regulatory units of the protein phosphatase 2A, may provide unique insights into the pathogenesis of neurodegeneration. RECENT FINDINGS: The first neuropathological examination of a brain from an SCA12 patient revealed both cerebellar and cerebral cortical atrophy, with a noted loss of Purkinje cells and no evidence of polyglutamine aggregates...

Spinocerebellar ataxia type-3 (SCA-3) is a rare disease but it is the most frequent type within the autosomal dominant inherited ataxias. The disease lacks an effective treatment to alleviate major symptoms and to modify disease progression. Our recent findings that endocannabinoid receptors and enzymes are significantly altered in the post-mortem cerebellum of patients affected by autosomal-dominant hereditary ataxias suggest that targeting the endocannabinoid signaling system may be a promising therapeutic option...

OBJECTIVE: Peripheral arterial disease (PAD) is a significant age-related medical condition with limited pharmacologic options. Severe PAD, termed critical limb ischemia, can lead to amputation. Skeletal muscle is the end organ most affected by PAD, leading to ischemic myopathy and debility of the patient. Currently, there are not any therapeutics to treat ischemic myopathy, and proposed biologic agents have not been optimized owing to a lack of preclinical models of PAD. Because a large animal model of ischemic myopathy may be useful in defining the optimal dosing and delivery regimens, the objective was to create and to characterize a swine model of ischemic myopathy that mimics patients with severe PAD...

OBJECTIVE: To determine if persons with chronic stroke and decreased hip and knee flexion during swing can walk with improved swing-phase kinematics when the task demands constrained gait to the sagittal plane. DESIGN: A one-day, within-subject design comparing gait kinematics under two conditions: Unconstrained treadmill walking and a constrained condition in which the treadmill walking space is reduced to limit limb advancement to occur in the sagittal plane. SETTING: Outpatient physical therapy clinic...

A 17-year-old male with no medical history noticed weakness of his limbs with imbalance and subsequent finger tremors. Physical examination revealed features of polyneuropathy, including diffuse weakness, distal symmetrical numbness with impaired deep sensation and areflexia in all limbs. Postural tremor was present in fingers. Ataxia was apparent in both lower limbs, causing a wide-based gait with a positive Romberg sign. Cerebrospinal fluid contained elevated total protein without pleocytosis. A nerve conduction study disclosed demyelinating features with prolonged terminal latencies, slow velocities with delayed F-wave latencies, and prominent temporal dispersion...

Impaired postural control is a cardinal symptom following concussion. Planned gait termination (GT) is a non-novel, dynamic task that challenges postural control in individuals with neurological deficits, and it could be an impactful measure for identifying dynamic postural control impairments following concussion. Therefore, the purpose of this study was to assess acute post-concussion dynamic postural control utilizing a planned GT task. The concussion participants (n=19, age: 19.0±0.8years, height: 177...

BACKGROUND: Leg length discrepancy greater than 1cm increases odds of progressive knee osteoarthritis in the shorter limb. METHODS: Biomechanical data of 15 knee osteoarthritis participants were collected while they walked under two conditions: (1) control - wearing thick sandals; (2) short limb - wearing a thin sandal on the osteoarthritic limb and a thick sandal on the contralateral limb. The thick and thin sandals had 1.45cm of thickness difference. The knee osteoarthritis limb was analyzed for both conditions...

Camurati-Engelmann disease (CED; MIM 131300), or progressive diaphyseal dysplasia, is a rare autosomal dominant bone disease, which is caused by mutations in the transforming growth factor‑β1 (TGFβ1) gene on chromosome 19q13.1‑13.3. Extremely variable penetrance has been reported to be associated with CED, the most common features of which are limb pain, waddling gait and muscle weakness. The present study reported on a consanguineous Chinese family with one affected individual that initially presented with exophthalmos, which has not previously been reported as an initial manifestation of CED...

In populations where walking and/or stopping can be difficult, such as in children with cerebral palsy, the ability to quickly stop walking may be beyond the child's capabilities. Gait termination may be improved with physical therapy. However, without a greater understanding of the mechanical requirements of this skill, treatment planning is difficult. The purpose of this study was to understand how healthy children successfully terminate gait in one step when walking quickly, which can be challenging even for healthy children...

PURPOSE: Patient recovery after a surgical procedure depends, among other factors, on the amount of the body weight with which patient loads lower limb. Research studies report different results of the degree of body weight with which lower limb is loaded during three-point crutch gait. The aim of this study was to evaluate the level of the ground reaction forces (GRF) during crutch gait used by patients after total hip arthroplasty (THA) in the first week after discharge from the orthopaedic units...
