To test for an association between the LRRK2-G2019S mutation and gait, we studied 52 first-degree relatives of patients with Parkinson’s disease (PD) who carry this mutation. An accelerometer quantified gait during usualwalking, fast-walking, and dual-tasking. Noncarriers (n 1⁄4 27) and carriers (n1⁄4 25) were similar with respect to age, gender, height, and gait speed during all conditions. Du...

Limit cycle walkers are a class of bipeds that achieve stable locomotion without enforcing full controllability throughout the gait cycle. Although limit cycle walkers produce more natural-looking and efficient gaits than bipeds that are based on other control principles such as zero moment point walking, they cannot yet achieve the stability and versatility of human locomotion. One open questi...

Walking speed is one marker of health in adulthood. Although personality may contribute to gait speed, there is limited longitudinal data on this association. Thus, the present study examined whether personality traits are prospectively associated with walking speed among middle aged and older adults. Participants were adults aged from 25 to 100 years old (N > 15,000) drawn from the Wisconsin L...

BACKGROUND It is known that general gait training improves lower extremity muscle strength and endurance in Diabetes Neuropathy (DN). But, it is still unknown whether Task-Oriented (TO) gait training would change gait biomechanics and the risk of falling in DN. TO gait training focuses on promoting timing and coordination of lower extremity movements through goal-directed practices with suffici...

PURPOSE Evaluate the relationship between neighborhood crime and the amount of daily walking by minority adults. DESIGN This was a cross-sectional study of minority adult walking behavior and crime. Setting. Oakland, California was chosen as the study area because of the substantial spatial variation in levels of criminal activity combined with detailed information on walking trips. PARTICI...

We reviewed 24 feet in 15 patients who had undergone talectomy for recurrent equinovarus deformity; 21 were associated with arthrogryposis multiplex congenita, two with myelomeningocele and one with idiopathic congenital talipes equinovarus. The mean follow-up was 20 years. Good results were achieved in eight feet (33%) in which further surgery was not needed and walking was painless; a fair re...

OBJECTIVES To study self reported knee joint problems and the energy costs of level walking in soccer players. METHODS Seventeen soccer players and twelve control subjects between 18 and 27 years old participated in the study. A questionnaire was used to establish the amount of participation in soccer and the frequency and extent of knee injuries. The physiological cost index (PCI) was used a...
