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...

The ability to negotiate stairs is important for community access and independent mobility but requires more effort and strength than level walking. For this reason, previous attempts to utilize functional neuromuscular stimulation (FNS) to restore stair navigation after spinal cord injury (SCI) have had limited success and are not readily generalizable. Stair descent is particularly challengin...

Functional testing is particularly useful in the clinic and for making research translatable; however, finding measures relevant across ages and different conditions can be difficult. A systematic review was conducted to investigate timed stair tests as an objective measure of functional abilities and musculoskeletal integrity. Data were analyzed for their ability to differentiate between contr...

This paper presents a stair-climbing mobile platform built on the Rocker–Bogie mechanism which enables to effectively climb up/down various sizes of stairs in indoor environments without violating its mobile stability. First, the link parameters of Rocker–Bogie mechanism are optimally chosen via the Taguchi method in order to make the trajectory of its center of mass (CM) as smooth as possible,...

In a vertical evacuation, there are two types of route that could be chosen namely ramp and stair. A is usually used to help disabled person with wheelchair reach the top shelter stair for normal persons. However, in an speed very important. Therefore, comparison between use stairs terms evacuation should evaluated. This paper presents evaluation using ramps by The study found evacuating slight...

Based on the molecular findings that many bitter taste receptors (T2Rs) are expressed within the same receptor cells, it has been proposed that bitter taste is encoded by the activation of discrete neural elements. Here we examined how a variety of bitter stimuli are represented by neural activity in central gustatory neurons. Taste responses (spikes/s) evoked by bathing the tongue and palate w...

The ability to taste bitterness evolved to safeguard most animals, including humans, against potentially toxic substances, thereby leading to food rejection. Nonetheless, bitter perception is subject to individual variations due to the presence of genetic functional polymorphisms in bitter taste receptor (TAS2R) genes, such as the long-known association between genetic polymorphisms in TAS2R38 ...

Background. Patellofemoral osteoarthritis (PF OA) is a leading cause of significant pain and disability of the knee joint. Stair climbing dysfunction is commonly reported in this cohort. Objectives. To compare the temporal muscle activation between females with PF OA and healthy controls during stair ascent and decide whether there is a link between altered core activity and Patellofemoral oste...
