Biomechanical analysis of step-up and step-down tasks in knee osteoarthritis: Insights from leading and trailing limbs.

Background: Stair climbing tests are pivotal when assessing physical performance in knee osteoarthritis patients, yet the biomechanical strategies that underpin poor stair climbing ability are heterogeneously reported. Single step tasks emulate a step-by-step gait pattern, an approach associated with knee pain when stair climbing. The objective of this study is to analyse the biomechanics and electromyography activity of both the leading and trailing limbs during single Step-up and Down tasks in knee osteoarthritis patients.

Background: Most cases of spinal muscular atrophy (SMA) can be diagnosed by copy number analysis of survival motor neuron (SMN) 1. However, a small number of cases of SMA can only be diagnosed by sequencing analysis. We present a case of SMA diagnosed 7 years after the onset of symptoms.

Objective: Electromyographic (EMG) signals show large variabilities over time due to factors such as electrode shifting, user behaviour variations, etc., substantially degrading the performance of myoelectric control models in long-term use. Previously one-time model calibration was usually required each time before usage.

Department of Rehabilitation Sciences, the Hong Kong Polytechnic University, Hong Kong Special Administrative Region of China. Electronic address:
Electromyography (EMG) is increasingly used in stroke assessment research, with studies showing that EMG co-contraction (EMG-CC) of upper limb muscles can differentiate stroke patients from healthy individuals and correlates with clinical scales assessing motor function. This suggests that EMG-CC has potential for both assessing motor impairments and monitoring recovery in stroke patients. However, systematic reviews on EMG-CC's effectiveness in stroke assessment are lacking.

Foam rolling is widespread and deeply rooted in exercise practice. The optimal duration and role of this treatment still lack scientific consensus. A relatively novel foam rolling treatment that combines vibration during application targets different muscle characteristics that are not well understood.
