Single-leg horizontal jump is more suitable for assessing lower limb function compared to single-leg vertical jump in patellofemoral pain patients.

Background: The single-leg vertical jump (SLVJ) and single-leg horizontal jump (SLHJ) are commonly used assessments for individuals with lower limb injuries. Despite previous studies comparing these tasks across various individuals, their comparative effectiveness in evaluating lower limb function in individuals with patellofemoral pain (PFP) and any potential sex differences in these functional tests remain uncertain.

Research Question: The purpose of this study was to determine which jump task is more suitable for functional assessment in PFP patients by comparing the differences in jump performance and biomechanical variables between PFP patients and healthy individuals during the SLVJ and SLHJ.

Gait strategies for individuals with knee osteoarthritis when transitioning between floor and stair walking.

Individuals with knee osteoarthritis are at higher risk for falls during transitions between floor and stair walking due to their reduced lower extremity function. However, the adjust gait characteristics of knee osteoarthritis subjects for dealing with stair transitions have not been explored. We aimed to investigate gait strategies in individuals with knee osteoarthritis compared to age-matched individuals without knee OA during the transition between walking on floor and stairs.

Postural Balance in Individuals With Knee Osteoarthritis During Stand-to-Sit Task.

Stand-to-sit task is an important daily function, but there is a lack of research evidence on whether knee osteoarthritis (knee OA) affects the postural balance during the task. This study aimed to compare individuals with knee OA and asymptomatic controls in postural balance and identify kinematic and lower extremity muscle activity characteristics in individuals with knee OA during the stand-to-sit task. In total, 30 individuals with knee OA and 30 age-matched asymptomatic controls performed the 30-s Chair Stand Test (30sCST) at self-selected speeds.

The Effect of Electroacupuncture on Dynamic Balance during Stair Climbing for Elderly Patients with Knee Osteoarthritis.

Background: Poor balance is one of the risk factors for falls in patients with knee osteoarthritis (KOA), which is related to the symptoms. Electroacupuncture (EA) is one of the traditional Chinese conservative methods commonly used to improve the symptoms in patients with KOA.

Objective: To assess whether EA increases the dynamic balance during stair negotiation among patients with KOA.

Effects of tai chi on postural control during dual-task stair negotiation in knee osteoarthritis: a randomised controlled trial protocol.

Introduction: Stair ascent and descent require complex integration between sensory and motor systems; individuals with knee osteoarthritis (KOA) have an elevated risk for falls and fall injuries, which may be in part due to poor dynamic postural control during locomotion. Tai chi exercise has been shown to reduce fall risks in the ageing population and is recommended as one of the non-pharmocological therapies for people with KOA. However, neuromuscular mechanisms underlying the benefits of tai chi for persons with KOA are not clearly understood.
