TL;DR: In this article, a micro-miniature overturning stair-climbing robot with a swinging arm component and an overturn driving component is presented. But the robot cannot realize large overturning movement on the basis of travelling on a flat ground.
Abstract: The invention discloses a micro-miniature overturning stair-climbing robot, based on the small overall size of the robot, a swinging arm component and an overturn driving component are added based on the robot in the prior art, the initial power transmission manner is changed, a corresponding mode is selected under the control of an external instruction, the robot disclosed by the invention can realize large overturning movement on the basis of travelling on a flat ground, with the overturning movement, the stair-climbing function is realized.

TL;DR: K4b2 is a highly reliable device for VO2 and VCO2 measurement during self-paced walking in free living environment during test-retest reliability tests.
Abstract: Introduction: K4b 2 (COSMED Srl Italy) is a portable device that is considered valid and reliable for measuring oxygen uptake (VO 2 ) and carbon dioxide production (VCO 2 ) under laboratory conditions. Objectives: Evaluate the test-retest reliability of K4b 2 during walking, stair climbing and descending stairs under free living conditions. Methods: Twelve participants completed two self-selected comfortable paced walking tests and 20 participants completed two self-selected comfortable paced stair climbing and descending tests. VO 2 and VCO 2 were measured during the tests using K4b 2 . Results: ICCs for VO 2 (ICC & 95% CI: 0.91, 0.72-0.97) and VCO 2 (0.91, 0.72-0.97) of walking demonstrated high reliability whereas reliability was moderate for stair climbing (VO 2 : 0.82, 0.6-0.93; VCO 2 : 0.73, 0.440.88) and low for descending stairs (VO 2 : 0.67, 0.33-0.85; VCO 2 : 0.51, 0.1-0.77). Conclusion: K4b 2 is a highly reliable device for VO 2 and VCO 2 measurement during self-paced walking in

TL;DR: The safe stair handrails are simple in structure, are easy to operate, and can protect a man climbing stairs during a process of stair climbing as discussed by the authors, and can be used to prevent a man from falling while climbing stairs.
Abstract: The invention discloses safe stair handrails Each stair handrail is internally provided with a chain transmission chamber; the chain transmission chamber is internally provided with a rotatable chain; the rotatable chain includes 4-6 T-shaped connection hooks; each stair handrail internally includes a T-shaped sliding block sliding groove communicating with the chain transmission chamber; two ends of each stair handrail are provided with a clamping groove communicating with the sliding block sliding groove respectively; the sliding block sliding groove includes a safe sliding block and a cargo sliding block which slide in the sliding block sliding groove and are connected to the connection hooks of the chain; the safe sliding block is provided with a semi-circular safe support rod; a handrail joint is internally provided with a joint inner chamber corresponding to the sliding block sliding groove; and the joint inner chamber includes two lines of rolling wheels for allowing the safe sliding block and the cargo sliding block to pass The safe stair handrails are simple in structure, are easy to operate, and can protect a man climbing stairs during a process of stair climbing

TL;DR: A symptom-limited stair climbing test is a safe, simple and low-cost method to evaluate the cardiopulmonary function preoperatively and can predict the occurrence of postoperative cardiopULmonary complications in non-small cell lung cancer patients.
Abstract: Objective To evaluate and compare the value of stair climbing tests and conventional pulmonary function tests in the prediction of postoperative cardiopulmonary complications in non-small cell lung cancer patients underwent surgery.Methods From April 1,2010 to Jan.30,2012,a total of 162 patients with thoracic carcinoma underwent stair climbing test (SCT) and conventional pulmonary function tests (PFT) preoperatively.The correlation of postoperative cardiopulmonary complications with the SCT and PFT parameters were analyzed retrospectively using chi-square test,independent sample t test and binary logistic regression analysis.Results Of the 162 patients,19 without operation were excluded,due to an advanced stage (9 cases),poor cardiopulmonary function (5 cases),rejecting operation (4 cases) and exploration alone (1 case).143 cases were eligible and evaluated eventually.Forty-one of the 143 patients (28.7%) had postoperative cardiopulmonary complications,but no death occurred.The patients were stratified into groups based on the time of stair climbing 5 stories (18.36 m,t,<92 s,≥92 s).Exercise oxygen desaturation(EOD) during the stair climbing test (< 5%,≥5%) and the difference between the pulse at resting state and the pulse at end of stair climbing test (AP,< 55 beats/min,≥55 beats/min),respectively.The rate of postoperative cardiopulmonary complications was significantly higher in the group with t ≥92 s,EOD≥5% and AP <55 beats/min (38.5%,42.0% and 35.1%,respectively) than that in the group with t <92 s,EOD <5% and AP≥55 beats/min (16.9%,21.5% and 18.2%,respectively).Binary logistic regression analysis showed that postoperative cardiopulmonary complications were independently correlated with EOD and lung function which did not meet the requirement of the lung resection operation mode.Conclusions A symptom-limited stair climbing test is a safe,simple and lowcost method to evaluate the cardiopulmonary function preoperatively.It can predict the occurrence of postoperative cardiopulmonary complications in non-small cell lung cancer patients.Conventional pulmonary function tests and stair-climbing test can be recommended to be routinely performed in all patients with nonsmall cell lung cancer before thoracic surgery.

TL;DR: The findings suggest that online peripheral visual information is more relevant when negotiating the first two steps, rather than the end of a staircase and that the steps subsequent the first few ones may require different information likely based on proprioception or working memory of the step height.
