Previous research on the biomechanics of stair negotiation has ignored the effect of the approaching speed. We examined if initiating stair ascent with a comfortable self-selected speed can affect the lower-extremity joint moments and powers as compared to initiating stair ascent directly in front of the stairs. Healthy young adults ascended a custom-built staircase instrumented with force plat...

BACKGROUND People with low back pain (LBP) alter their motion patterns during level walking and stair climbing due to pain or fear. However, the alternations of load sharing during the two activities are largely unknown. The objective of this study was to investigate the effect of LBP caused by lumbar disc herniation (LDH) on the muscle activities of 17 main trunk muscle groups and the intradis...

Joint biomechanics during stair walking may contain important information on functional deficits in patients with orthopaedic conditions but depend on the stair dimension. The goal of this study was to compare knee kinematics and kinetics between patients with good outcome 2 years after total knee arthroplasty (TKA) and age-matched controls during stair ascent and descent at two different stair...

[Purpose] The aim of this study was to determine the effect of stair task training on gait abilities by conducting stair task training. In this training, step training is applied in various directions with hemiplegia patients. [Subjects and Methods] Thirty-six patients with stroke were selected on the basis of inclusion and exclusion criteria, and they were randomly divided into eighteen patien...

<b><i>Hintergrund:</i></b> Aktuelle Leitlinien empfehlen phasenbasierte Behandlungsansätze wie das Skills-Training zur Affektiven und Interpersonellen Regulation mit Narrativer Therapie (STAIR/NT) Behandlung der Posttraumatischen Belastungsstörung nach komplexer Traumatisierung. Bislang ist jedoch keine systematische Übersicht Wirksamkeit ersten Therapiephase STAIR von S...

An adaptive slicing procedure for improving the geometric accuracy of layered manufacturing techniques is presented. Unlike previous procedures, the present method uses layers with sloping boundary surfaces that closely match the shape of the required surface. This greatly reduces the stair case effect which is characteristic of layered components with square edges. Two measures of error are co...

OBJECTIVE To examine using surface electromyography whether stair climbing with abdominal hollowing (AH) is better at facilitating local trunk muscle activity than stair climbing without AH. METHODS Twenty healthy men with no history of low back pain participated in the study. Surface electrodes were attached to the multifidus (MF), lumbar erector spinae, thoracic erector spinae, transverse a...

Enterprise storage clusters increasingly adopt erasure coding to protect stored data against transient and permanent failures. Existing erasure code designs not only introduce extra parity information in a storage-inefficient manner, but also consume substantial cross-rack recovery bandwidth. To relieve both storage and recovery burdens of erasure coding, we adapt our previously proposed STAIR ...
