Weighted stair climbing in mobility-limited older people

Posted: 2017-12-16 10:43

                                            For people in wheelchairs or those who use walkers, the ability to move freely between rooms is important.

                                            Widening hallways or doorways can help lower the risk of falls when maneuvering with a walker or a

                                            wheelchair. Adding ramps where there are steps can also improve access to a room. Make Life Easier -

                                            Whether it's hauling a 100-pound cabinet up five flights of stairs or bringing home the groceries, the Dragon

                                            makes transport and storage easy, painless, and hassle free.

                                            Innovative Design - The Upcart wasn't a Kickstarter Staff Pick for nothing. In addition to being an accomplished

                                            climber, this stair climber chair has the versatility and durability of something twice its size but folds to a depth

                                            of only 4 inches. Did we mention it's lightweight too? Adjustable, Collapsible, and Easily Stored - Our self-locking,

                                            spring-assisted handcart collapses in a second, and the adjustable handle allows you to select optimum heights

                                            for both level and unlevel surfaces. Built To Last - The UpCart's modular frame is made from precision cast

                                            aluminum alloy parts, which are stronger than plastic, and features non-marking rubber tires, shielded ball bearings,

                                            and powder-coating to protect it from wear and tear.

                                            Generalized joint hypermobility (GJH) is a frequent entity in rheumatology with higher prevalence among women. It

                                             is associated with chronic widespread pain, joint dislocations, arthralgia, fibromyalgia and early osteoarthritis. Stair

                                            climbing is an important functional task and can induce symptoms in hypermobile persons. The aim of this study was

                                            to compare ground reaction forces (GRF) and muscle activity during stair climbing in women with and without GJH. A

                                            cross-sectional study of 67 women with normal mobility and 128 hypermobile women was performed. The hypermobile

                                            women were further divided into 56 symptomatic and 47 asymptomatic. GRFs were measured by force plates embedded

                                            in a six step staircase, as well as surface electromyography (EMG) of six leg muscles. Parameters derived from GRF and

                                            EMG were compared between groups using t-test and ANOVA. For GRF no significant differences were found. EMG

                                            showed lower activity for the quadriceps during ascent and lower activity for hamstrings and quadriceps during descent

                                            in hypermobile women. For symptomatic hypermobile women these differences were even more accentuated. The

                                            differences in EMG may point towards an altered movement pattern during stair climbing, aimed at avoiding high muscle

                                            activation. However, differences were small, since stair climbing seems to be not demanding.
