purpose: the purpose of this study was to investigate the effect of kinesio-taping on the range of motion of cervical lateral flexion point in subjects with trigger point in upper trapezius muscle. methods: a total of 32 subjects with myofascial trigger point in upper trapezius participated in this randomized controlled trial (rct). the subjects were randomly assigned to two groups: kinesio-tap...

A characteristic of scapulothoracic dysfunction is the tendency for the upper regions of the trapezius to hypertrophy in relation to its middle and lower portions. This creates a muscular imbalance that can alter scapular position and subsequently the length-tension relationship of the shoulder muscles. Tape was applied over the right upper trapezius to inhibit electrical activity in the muscle...

[Purpose] In this study, we compared upper cervical flexion and cervical flexion angle of computer workers with upper trapezius and levator scapular pain. [Subject] Eight male computer workers with upper trapezius muscle pain and eight others with levator scapular muscle pain participated. [Methods] Each subject was assessed in terms of upper cervical flexion angle and total cervical flexion an...

[Purpose] To measure the activities of the upper, middle, and lower trapezius and serratus anterior muscles during shoulder abduction at two angles and compare their relative isolation. [Subjects and Methods] Ten men were enrolled. The tester measured the isolation ratios of upper, middle, and lower trapezius and serratus anterior muscles during shoulder abduction exercises at 60° and 120°. [Re...

[Purpose] This study investigated upper-extremity muscle activities in natural, ideal, and corrected head positions. [Subjects and Methods] Forty subjects with a forward head posture and rounded shoulder were recruited and randomly assigned to the natural head position group (n = 13), ideal head position group (n = 14), or corrected head position group (n = 13). Muscle activities were measured ...

[Purpose] The purpose of this study was to examine the effects of the cervical flexion angle on muscle fatigue and pain in the cervical erector spinae and upper trapezius in normal adults in their 20s. [Subjects and Methods] The study's subjects were 14 normal adults. After sitting on a chair with their back against the wall, they held a smartphone with both hands for 10 minutes and fatigue and...

OBJECTIVES To describe and compare the activation levels of the upper and lower trapezius muscle and study the influence of trunk and lower extremity position or movement during eight variations of a scapular retraction exercise. DESIGN Descriptive study. Exercise performance was standardized and individualized based on height, age and body weight. METHODS Individual muscle activation was c...

Pain and tenderness of the upper trapezius are the major complaints among people with chronic neck and shoulder disorders. Hyper-activation and increased muscle tension of the upper trapezius during arm elevation will cause imbalance of the scapular muscle force and contribute to neck and shoulder disorders. Assessing the elasticity of the upper trapezius in different arm positions is therefore...
