TL;DR: The results identify the importance of the starting position in experiments dealing with biomechanics of stair negotiation and have important implications for studying stair ascent characteristics of other populations such as older adults.

TL;DR: In this first study on stairs, lateral wedge insoles consistently reduced the overall magnitude of medial compartment loading during stair ascent and descent.

TL;DR: A commercially available three-axis accelerometer was used to characterize the activities and body postures of individuals with transtibial amputation and the classifier achieved a mean +/- standard deviation accuracy of 96.6% +/- 3.0%.
Abstract: Knowledge of how persons with amputation use their prostheses and how this use changes over time may facilitate effective rehabilitation practices and enhance understanding of prosthesis functionality. Perpetual monitoring and classification of prosthesis use may also increase the health and quality of life for prosthetic users. Existing monitoring and classification systems are often limited in that they require the subject to manipulate the sensor (e.g., attach, remove, or reset a sensor), record data over relatively short time periods, and/or classify a limited number of activities and body postures of interest. In this study, a commercially available three-axis accelerometer (ActiLife ActiGraph GT3X+) was used to characterize the activities and body postures of individuals with transtibial amputation. Accelerometers were mounted on prosthetic pylons of 10 persons with transtibial amputation as they performed a preset routine of actions. Accelerometer data was postprocessed using a binary decision tree to identify when the prosthesis was being worn and to classify periods of use as movement (i.e., leg motion such as walking or stair climbing), standing (i.e., standing upright with limited leg motion), or sitting (i.e., seated with limited leg motion). Classifications were compared to visual observation by study researchers. The classifier achieved a mean +/- standard deviation accuracy of 96.6% +/- 3.0%.

TL;DR: Meta-analysis revealed that kinematic and kinetic alterations during stair climbing associated with knee OA were lower external knee flexion moment in conjunction with a larger trunk/hip flexion angles and smaller kneeflexion/ankle dorsiflexion angles.

TL;DR: In this article, a stair-type exercise apparatus is described in which two pedal members reciprocate and the pedal members can either be directly connected together by a cog drive belt which in turn operates through a transmission providing a resistive force to the pedals or the pedals can be individually connected to the transmission by a drive belt.
Abstract: A stair type exercise apparatus is disclosed in which two pedal members reciprocate. The pedal members can either be directly connected together by a cog drive belt which in turn operates through a transmission providing a resistive force to the pedals or the pedals can be individually connected to the transmission by a drive belt. The resistive force is supplied by an alternator which is controlled by a computer.
