Upper trapezius stretch

Movement

The position studies describe

In one study’s stretch positions, the head bent to the side, away from the muscles being measured¹. That study, in healthy men, concluded that bending the neck forward, then to the side away, could lengthen the upper trapezius well¹. The same study said this of the splenius capitis, a muscle at the back of the neck¹. Bending forward is flexion, and bending to the side is lateral flexion (bending the spine to the side)¹.

The versions studies have used

The studies on this page used several related stretches, done alone or by another person^5,6:

• A self-stretching routine of seven exercises, starting with neck lateral flexion, with its static stretches held for 20 seconds for five sets⁵.
• A manual stretch of the upper trapezius, given by another person⁶.
• Passive stretching, in volunteers with a latent trigger point (a tender knot) in the muscle⁷.
• A levator scapulae (a muscle running from the neck to the top of the shoulder blade) stretch, sitting or on hands and knees⁸.

What it loads

The upper trapezius

The trapezius (the large muscle across the upper back and neck that moves the shoulder blade) has upper, middle and lower groups of fibres^9,10. Its upper fibres can raise and upwardly rotate the shoulder blade and extend the neck⁹. In dissection studies, fibres from the back of the skull and the neck’s ligament ran mainly across to the collarbone¹¹.

One dissection study disagreed that the upper fibres lift the shoulder blade directly, because they run mostly across¹¹. It argued they draw the shoulder blade and collarbone back instead, or raise the shoulder blade by turning the collarbone¹¹.

What elastography showed

One study measured neck muscles in 15 healthy men using shear wave elastography, an ultrasound method that estimates how stiff a tissue is¹. The authors read a stiffer muscle in a held position as a more lengthened one¹:

Muscle	Stiffer than at rest in
Upper trapezius	Positions combining forward bending with bending away1
Splenius capitis	Positions combining forward bending with bending away1
Levator scapulae	Each position that included bending away, compared with rest or forward bending alone1

The levator scapulae

A second study looked at the levator scapulae alone⁸. In 24 university students with a shortened levator scapulae, stretching it while sitting increased its measured length more than stretching on hands and knees⁸. Neck range of motion, how far a joint moves during a movement, also rose more with the sitting stretch⁸.

The median nerve, in one arm position

A study in cadavers (bodies donated for study) looked at a nerve rather than a muscle¹². The arm was placed in a set test position for the nerves of the arm¹². The median nerve is a main nerve of the forearm and hand. Bending the neck away from that arm pulled it at the wrist toward the neck and raised its strain¹². The strain changes were significant at three of four elbow angles tested, and a nearby finger-flexing muscle did not change¹².

Blood pressure and neck arteries

In healthy adults in their 20s and 40s, systolic (upper-number) and mean blood pressure fell after a session of trapezius self-stretching⁵. Heart rate did not change significantly⁵.

Two studies of other neck stretches measured the neck’s arteries^13,14. In 30 men without symptoms, the head was held turned fully to the opposite side for 60 seconds¹³. The vertebral artery runs up through the neck bones to the brain. Its peak systolic blood speed fell by 39.1 percent, compared with the head held straight¹³.

In 17 healthy young adults, 15 minutes of ten neck stretches raised carotid artery compliance (how readily the artery wall gives)¹⁴. Each stretch was held 30 seconds, and sitting at rest did not raise it¹⁴. Of the two artery studies, one tested a rotation stretch and the other a mixed session, not this stretch alone^13,14.

How the body adapts

Stiffness and pain sensitivity after one session

In 22 healthy young adults, upper trapezius stiffness fell after a session of trapezius self-stretching². Their own rating of shoulder stiffness fell too². In a second study, stiffness fell in 18 people in their 20s but not significantly in 8 people in their 40s⁵. Both studies used strain elastography, another ultrasound measure of stiffness^2,5.

One randomised trial, a study that assigns people to groups by chance, took 102 healthy people with no significant neck pain history⁶. A manual upper trapezius stretch was compared with a control group⁶. A third group was given a thrust manipulation⁶. Pressure pain threshold, the pressure at which pressing on a spot starts to hurt, changed differently over time across the three groups⁶. Changes in neck extension and side bending favoured the stretch group over the controls⁶.

In dental professionals, pressure pain thresholds rose at 15 upper-body points after 30 minutes of stretching following work¹⁵. The points included the upper trapezius and the levator scapulae¹⁵.

Trials in people with sore spots in the muscle

Trapezius myalgia is a common complaint of pain, stiffness and tightness in the upper trapezius, often linked to static, repetitive work¹⁶. In a systematic review of neck and shoulder disorders, five of seven studies put the upper trapezius among the muscles with the most trigger points¹⁷. The same review called the evidence for a high trigger-point rate limited; all seven studies were small¹⁷.

Several trials studied stretching in people with trigger points or myofascial (muscle and connective tissue) pain^7,18:

Who was studied	What was found
117 volunteers with a latent trigger point from computer work	Passive stretching had large immediate effects on side bending away, turning toward the same side, and pain threshold7
The same 117 volunteers, a day and a week later	The stretching effects were not maintained; the ischaemic compression (sustained pressure) group alone kept its effect size7
Women aged 30 to 59 with myofascial pain, 30 per group	Pain threshold at the upper trapezius rose after self-stretching, with or without mindful breathing19
43 people with myofascial pain syndrome and trigger points	Self neck-stretching alone improved pain, pain threshold and side bending away less than stretching plus either of two needle methods20
60 physiotherapy students with neck pain and active trigger points	After four weeks, the stretching-only group showed no significant change in any measure except pain rating18
19 people with myofascial neck pain	Acupuncture plus stretching raised pain threshold 11 percent just after the session; the methods no longer differed at 15 and 30 minutes21

A systematic review of single exercise sessions in long-term, non-specific neck pain found that active stretching had contradictory effects on pain sensitivity²².

Trials of neck-stretching programmes

The trials below tested stretching programmes; the office-worker trial, for example, used neck and shoulder stretching³.

The Cochrane review looked at stretching alone and stretching combined with strengthening separately⁴. In adults with long-term neck pain, it found low-quality evidence that stretching alone may not change pain or function in the short term⁴. Its authors concluded that no benefit may be expected when stretching is used alone⁴. The same review found moderate-quality evidence that combined neck, shoulder and shoulder-blade strengthening and stretching had a small to large benefit for pain⁴. A systematic review in office workers with neck pain found one stretching trial, which reported less neck pain²³. The authors said its effect needs further study²³.

Single trials found these results^3,24:

• In 96 office workers with neck pain for three months or more, one group added neck and shoulder stretching to an ergonomics brochure³. After four weeks, that group improved more in pain than the brochure-only group³.
• That group was asked to stretch twice a day, five days a week³. Within that group, people who stretched three or more times a week improved more in neck function than those stretching less³.
• In a trial of 142 office workers with neck, shoulder and lower back pain that included a stretching group, neck pain scores differed significantly between groups²⁵.
• In 125 women with non-specific neck pain, pain fell over four weeks with stretching or manual therapy, with no significant difference²⁶.
• In those women, stretching was five times a week and manual therapy twice²⁶. A disability index and neck stiffness fell more after manual therapy than after stretching²⁶. In a report of 125 women randomised to manual therapy then stretching, or stretching then manual therapy, neck mobility and strength improved similarly in both groups²⁷.
• In 101 people with long-term neck pain, pain and disability fell over a year of home stretching, with or without strength training²⁸. The two groups did not differ significantly²⁸.
• In 180 female office workers with long-term neck pain, all groups were advised to stretch and do aerobic exercise²⁹. The authors found those alone much less effective than strength training²⁹.
• In 57 women with long-term neck pain, a year of home strength training or stretching did not differ in the trial’s two main outcomes²⁴. The authors said this may reflect low statistical power²⁴.
• In 38 people with non-specific neck pain, stretching was added to mobilisation and rotation exercises³⁰. The authors suggested it may improve extension, right rotation and side bending more, but not pain or disability³⁰.

In women aged 35 to 60 with chronic neck pain, one trial found less pain and more range after static stretching plus manual therapy³¹. It did not differ significantly from muscle-chain stretching³¹. These gains were slightly reduced at a follow-up six weeks later³¹.

A meta-analysis pools the results of several earlier studies to get one combined answer. One such analysis, of nine trials with 1026 people after thyroid surgery, linked neck stretching with better pain scores at one week and one month³². The pooled results varied between trials³².

Progressive overload

A 2026 position stand on resistance training describes progressive overload as the need to increase the stimulus placed on the muscle throughout a training programme³³. One trial lengthened the hold over the weeks³⁴. Other studies report the hold, repeats or sessions a week they used^35,36.

Longer holds over six weeks

In a trial of 39 office employees with non-specific long-term neck pain, the stretching group did static stretches three times a week for six weeks³⁴. The stretches included the upper trapezius and the levator scapulae³⁴. The paper’s text reports the hold rising from 15 seconds in the first week to 30 seconds in the last³⁴. Pain fell significantly after six weeks, both with stretching and with a tissue release programme³⁴.

Holds and repeats in other studies

• In 47 female university students, the stretch was held 10 seconds, three times a set, for three sets³⁵.
• In a trial of 33 women aged 35 to 60 with long-term neck pain, one group held each stretch twice for 30 seconds³¹. They had two 1-hour sessions a week for six weeks³¹.
• In 30 patients with neck pain from upper trapezitis (a sore upper trapezius), a stretch was held 10 to 60 seconds³⁷. It followed a muscle energy technique (a hands-on method in which a person tightens a muscle against another person’s resistance, then the muscle is stretched) known as reciprocal inhibition, five sessions a week for two weeks³⁷. Comparing the one group before and after, pain, neck range and a disability score improved³⁷.

How often, and for how long

These trials set how often people stretched, and for how many weeks^36,38:

Who was studied	What was found
43 taxi drivers with non-specific long-term neck pain	Self-stretching three times a day for 4 weeks was added to kinesio tape (stretchy tape on the skin)36. It gave benefits over tape alone in pain, pressure pain threshold, disability and neck range36
131 adults with persistent or recurring neck pain	Home stretching was set at daily for the 2-week trial39; all who returned a diary stretched on at least 10 of 14 days39
125 women with long-term neck pain	After stretching five times a week for 4 weeks, the authors found neck strength changes minor27
60 participants	Cryotherapy (cold) with mobilisation reduced neck pain and disability more than the same plus home stretching five times a week for 5 weeks40
48 community-dwelling women aged about 75	Supervised upper-body stretching twice a week for 12 weeks did not change neck range of motion38

Connections

The muscles it stretches

In one study of healthy men, the upper trapezius was stiffer with the neck bent forward and away, read as more lengthened¹. The same study found the splenius capitis stiffer with the neck bent forward and away¹. It found the levator scapulae stiffer in each position that bent the neck away¹.

The nerve it can strain in one arm position

In cadavers with the arm in a nerve-test position, bending the neck away strained the median nerve¹².

An exercise for the same fibres

In 30 healthy people across ten exercises, the one-arm shrug produced the most upper trapezius activity⁴¹.
