Trunk Muscle EMG During Intermediate Pilates Mat Exercises in Beginner Healthy and Chronic Low Back Pain Individuals.

Objective: The purpose of this study was to compare the electromyographic pattern of core muscles during intermediate Pilates mat exercises between healthy people and those with low back pain.

Methods: We evaluated healthy participants (n = 19; mean ± standard deviation [SD]: age 28 ± 8 years, body mass 65 ± 10 kg, height 160.0 ± 9.

The effect of pillow height on muscle activity of the neck and mid-upper back and patient perception of comfort.

Objective: The purpose of this study was to evaluate the comfort and the electromyographic (EMG) activity of the neck and mid-upper back of asymptomatic adults using foam pillows of 3 different heights.

Methods: Twenty-one asymptomatic adults used foam pillows of 3 different heights (1: 5 cm, 2: 10 cm, and 3: 14 cm). Comfort was assessed using a 100-mm visual analog scale.

Biomechanical variables and perception of comfort in running shoes with different cushioning technologies.

Objectives: To investigate the relationships between the perception of comfort and biomechanical parameters (plantar pressure and ground reaction force) during running with four different types of cushioning technology in running shoes.

Design: Randomized repeated measures.

Methods: Twenty-two men, recreational runners (18-45 years) ran 12km/h with running shoes with four different cushioning systems.
