This paper focuses on step length estimation using inertial measurement sensors. Accurate has a number of useful health applications, including its use in characterizing the postural instability Parkinson’s disease patients. Three different sensor configurations are studied sensors shank and/or thigh human subject. The problem several challenges due to unknown bias, misalignment body and desire...

recently the stepped spillways have been used as an appropriate solution for energy dissipation. in the present study, siahbisheh dam spillway is simulated by using computational fluid dynamic (cfd), in which the mixture method and reynolds stresses model (rsm) turbulence model is used. in the first modeling series the over all steppes slope is constant. the number of the steps is increased to ...

Freezing of gait (FOG) has been identified as one of the main contributors to gait disturbances in Parkinson's disease. While the pathophysiology remains enigmatic, several factors such as step length and the sequence effect (step to step reduction in amplitude) may lead to the occurrence of FOG. It was hypothesized that by reducing step length, FOG episodes would present more frequently if a s...

BACKGROUND Stepping is a common technique for balance recovery. Previous studies have shown that elderly adults are less able than young adults to recover balance by stepping, apparently due to reductions in step length and step speed. We sought to clarify these relations by testing the hypothesis that step length and step speed affect the ability of young and elderly women to recover balance. ...

OBJECTIVES To compare gait patterns in older women with and without peripheral neuropathy (PN) in standard (smooth surface, normal lighting) and challenging environments (CE) (irregular surface, low lighting). DESIGN Observational, controlled study of 24 subjects. SETTING Biomechanical research laboratory. PARTICIPANTS Twenty-four older women, 12 with PN and 12 without PN (mean age +/- st...
