BACKGROUND After severe brachial palsy involving the shoulder, many different muscle transfers have been advocated to restore movement and stability of the shoulder. Paralysis of the deltoid and supraspinatus muscles can be treated by transfer of the trapezius. METHODS We treated 10 patients, 8 males and 2 females, by transfer of the trapezius to the proximal humerus. In 6 patients the C5 and...

INTRODUCTION The utility of rehabilitative ultrasound imaging (RUSI) for assessing trapezius muscle contractile characteristics was investigated by examining whether muscle thickness changes during contraction (CT) differed between people with and without mild shoulder pain. METHODS In 18 subjects with mild shoulder pain (aged 28±8 years) and 18 matched controls, trapezius muscle thickness ch...

Near work is associated with increased activity in the neck and shoulder muscles, but the underlying mechanism is still unknown. This study was designed to determine whether a dynamic change in focus, alternating between a nearby and a more distant visual target, produces a direct parallel change in trapezius muscle activity. Fourteen healthy controls and 12 patients with a history of visual an...

We have reviewed 26 patients treated by trapezius transfer for deltoid paralysis due to brachial plexus injury or old poliomyelitis. We assessed the power of shoulder abduction and the tendency for subluxation. There were good results in 16 patients (60%); five were fair and five poor. Trapezius transfer appears to give reasonable results in the salvage of abductor paralysis of the shoulder.

introduction: an otogenic brain abscess is a common ent problem but an otogenic trapezius abscess can also be experienced in otolaryngological practice, particularly in patients with chronic suppurative otitis media.   case report: we report a rare case of a trapezius abscess in an eight-year-old girl who presented at the ent, head and neck surgery postgraduate medical institute, lady reading h...

BACKGROUND Repetitive and stressful work tasks have been linked to the development of pain in the trapezius muscle, although the underlying mechanisms still remain unclear. In earlier studies, it has been hypothesized that chronic muscle pain conditions are associated with imbalance in the autonomic nervous system, predominantly expressed as an increased sympathetic activity. This study investi...

BACKGROUND Work-site strength training sessions are shown effective to prevent and reduce neck-shoulder pain in computer workers, but difficult to integrate in normal working routines. A solution for avoiding neck-shoulder pain during computer work may be to implement high intensity voluntary contractions during the computer work. However, it is unknown how this may influence productivity, rate...

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...

The association of cytochrome c oxidase negative fibres (COX-negative) and ragged-red fibres (RR-fibres) with work related trapezius myalgia has been proposed. Hitherto studies have been small or without control groups. The aim of the present study was to investigate the prevalences of RR-fibres and COX-negative fibres in female cleaners with (n=25) and without (n=23) trapezius myalgia and in c...

The motor output of the medial pontomedullary reticular formation (mPMRF) was investigated using stimulus-triggered averaging (StimulusTA) of EMG responses from proximal arm and shoulder muscles in awake, behaving monkeys (M. fascicularis). Muscles studied on the side ipsilateral (i) to stimulation were biceps (iBic), triceps (iTri), anterior deltoid (iADlt), posterior deltoid (iPDlt), and lati...
