Palmaris Longus Muscle 



Median Nerve Stretch


Pain from Palmaris Longus Trigger Points is typically experienced as a needle-like sensation

The Palmaris Longus decelerates extension of the hand at the wrist while decelerating supination of the hand against gravity and extension of the forearm at the elbow.

A focal point of pain from the palmaris longus is experienced as a needle-like sensation, rather than the deep aching pain of myofascial trigger points in many other muscles.

Pain can extend to the base of the thumb and the distal crease of the palm. A residue of this pain can travel to the distal volar forearm.

Part of the superficial layer, which also includes the pronator teres, flexor carpi radialis, and flexor carpi ulnaris.

The palmaris longus muscle is absent in 13% of the population.


Palmaris Longus Trigger Points

Palmaris Longus - Common Trigger Point Site



Common flexor origin on anterior aspect of medial epicondyle of humerus.


Superficial (front) surface of flexor retinaculum and apex of palmar aponeurosis.


Flexes wrist. Tenses palmar fascia.

Antagonists: extensor carpi radialis brevis, extensor carpi radialis longus, extensor carpi ulnaris.


Median nerve, C(6), 7, 8, T1. 

Basic Functional Movement

Examples: grasping a small ball; cupping palm to drink from hand.


Palmaris Longus Trigger Points Pain Map

Palmaris Longus Trigger Points - Typical Referred Pain Pattern


Trigger Point Referred Pain Patterns

Diffuse pain in anterior forearm; intense pain zone 2–3 cm in palm of hand, surrounded by a superficial zone of prickling and needle-like sensations.


Pain and “soreness” in palm of hand, tenderness in hand/palm, functional loss of power in grip, tennis elbow.


Direct trauma (e.g. fall on outstretched arm), occupational, racquet sports, digging in palm.

Differential Diagnosis

Neurogenic pain. Dupuytren’s contracture. Carpal tunnel syndrome. Complex regional pain syndrome (reflex-sympathetic dystrophy). Scleroderma. Dermatomyositis.


Flexor carpi radialis, brachialis, pronator teres, wrist joints (carpals), often associated with middle head of triceps brachii.

Self Help

Self-massage techniques can be helpful, especially using balls.


Avoid prolonged “gripping,” especially of power tools. Stretching and heat. Regular breaks.

Scraping, a manual, ancient practice where pain points are worked with a gua sha (smooth-edged tool), reportedly increases blood flow by up to 400 per cent more than foam rolling and massage guns. By breaking up old, damaged blood vessels to promote new growth and healing, these tools are useful for getting into the nooks and crannies of a pain point, especially in delicate areas like along the shin muscles and under the foot.

Tim Tian has taken the scraper idea and supercharged it, creating a manual, triangular tool that blends heat and vibration therapy. “Cold blades stiffen muscles, blocking a deep release,” he says.

The heated scraper device takes just three seconds to reach 50ºC. This helps muscles soften, making it easier to massage away tension, increase blood flow and promote healing. The scraper is specially great for alleviating delayed onset muscle soreness (DOMS) in the quads, and provides a relaxing switch-up from the foam roller slog.
