TL;DR: In this article, a hanging-type stair climbing cart with a bearing system, a supporting system, one matter carrying system and one power device is described. But the design of the bearing system was not discussed.
Abstract: The hanging type stair climbing cart includes one bearing system, one supporting system, one matter carrying system and one power device. The bearing system consists of a cross beam over the stair railing and an inside column on inside of stair railing; the matter carrying system is one article carrier connected to the inside column; and the supporting system including an outer column, wheels, a chain and a support board can prevent the cart from sliding down and reduce cart moving resistance. The present invention has the advantages of simple structure, low cost, etc.

TL;DR: The test-retest reliability of the ST was very high for the patients with THA, and the SEM and MDC90 were adequate for clinical use, suggesting the ST is less time consuming and has very high reliability to measure the functional level after THA in the clinical setting.
Abstract: PurposeStair climbing is one of the important functional activities of daily living to maintain mobility and independence. Walking and stair climbing have been identified by clinicians and patients...

TL;DR: The TENS intervention may be an option for reducing the burden of early-stage knee OA and post-hoc correlation analyses revealed a non-significant but positive relationship between the pain relief effect and improved 11-step SCT time in the TENS group but not in the sham-TENS group.
Abstract: This study aimed to examine the effect of transcutaneous electrical nerve stimulation (TENS) on stair climbing capacity in individuals with pre-radiographic to mild knee osteoarthritis (OA). This is a secondary analysis of data from a single, participant-blinded, randomized controlled trial with a pre-post design. Participants with pre-radiographic to mild knee OA (mean age, 59.1 years; 72.9% women) were randomly assigned into two groups, a TENS (n = 30) and a sham-TENS groups (n = 29). TENS or sham-TENS treatments were applied to all participants by using the prototype TENS device with pre-specified parameters. The primary outcome measures included valid and reliable functional measures for stair climbing (stair-climb test [SCT]), visual analog scale for knee pain during the SCT, and quadriceps muscle strength. TENS improved SCT time by 0.41 s (95% confidence interval [CI]: 0.07, 0.75). The time reduction in the transition phase explains the TENS therapeutic effect. Post-hoc correlation analyses revealed a non-significant but positive relationship between the pain relief effect and improved 11-step SCT time in the TENS group but not in the sham-TENS group. These results indicate that the TENS intervention may be an option for reducing the burden of early-stage knee OA.

29 Jul 2010TL;DR: A statics model of the wheelchair for the starting stage of stair-climbing is developed and results prove that the wheelchair can climb stairs stably when it takes advantage of tension estimation algorithm.
Abstract: To meet the rapid increasing demand of the equipment assisting the disabled and the old, a novel style transmuting track wheelchair robot is developed. It has the characteristic that the track tension can be determined dynamically. Compared to traditional method that keeps track tension constantly, dynamically determining tension can reduce power consumption obviously. Based on the fact that modeling track tension is complex, a fuzzy logic decision making method is developed to estimate the proportion of various factors that have effect on track tension. Combining with least square method, we get track tension optimal estimation algorithm. Considering the low speed characteristic of the wheelchair as climbing stairs and the track tension got by estimation algorithm, the paper develops a statics model of the wheelchair for the starting stage of stair-climbing. Simulation results prove that the wheelchair can climb stairs stably when it takes advantage of tension estimation algorithm.
