LI 15, also known as Shoulder Bone or Jianyu, is a major point on the Large Intestine meridian and plays a central role in acupressure protocols for shoulder health. Located at the front of the shoulder joint, this point is particularly useful for promoting mobility, reducing stiffness, and alleviating localized pain.
Primary uses of LI 15 include:
- Relieving shoulder stiffness and frozen shoulder
- Supporting range of motion and joint mobility
- Reducing local inflammation or muscular tightness
Alternate names: Jianyu (LI 15), Large Intestine 15.
Summary Table
| Attribute | Details |
|---|---|
| Pressure Point Name | Shoulder Bone – LI 15 (Jianyu) |
| Body Area | Shoulder |
| Exact Location | Lateral shoulder, in the depression anterior to the acromion |
| Common Uses | Frozen shoulder, shoulder pain, arm weakness |
| Stimulation Technique | Firm circular or static thumb pressure for 1–2 minutes |
| Contraindications | Avoid overuse in cases of acute bursitis or inflammation |
Clinical Significance & Associated Conditions
LI 15 is a cornerstone point in treatments targeting shoulder pain and dysfunction, including:
- Adhesive capsulitis (frozen shoulder)
- Deltoid and rotator cuff strain
- Restricted abduction and flexion of the arm
- Peripheral nerve entrapment affecting the upper limb
Energetically, this point helps release stagnant yang qi in the upper body, aiding in circulation and energy flow through the arm. It is often selected when the shoulder is “locked” from physical overuse or energetic stagnation.
Location
To locate LI 15:
- Raise the arm slightly (about 30–45 degrees from the body).
- Identify the acromion (bony tip of the shoulder).
- The point lies in the anterior depression just in front of the acromion, at the junction of the deltoid and the shoulder capsule.
Looking for an easier way to use this point in your wellness routine?
This pressure point is simple to locate and even easier to apply when guided step-by-step. It’s featured in over 70 evidence-based pressure point protocols inside our Pressure Points Guide app. Whether you’re looking to improve shoulder mobility, ease tension, or recover from stiffness, the app guides you through every session with visuals and audio.

How to Stimulate It
- Tool: Use your thumb, middle finger, or massage tool with a rounded edge.
- Pressure: Medium to firm—adjust based on pain sensitivity.
- Duration: Hold for 1–2 minutes; use slow circular motion if desired.
- Position: Best accessed with the arm relaxed or partially raised.
- Frequency: Daily or before/after shoulder exercise routines.
- Paired with: SI 11 and LI 4 to enhance upper limb circulation and tension release.
Benefits and Common Uses
The Shoulder Bone pressure point is particularly valuable for:
- Pain relief: Eases localized inflammation and muscle tightness
- Joint function: Improves movement in the glenohumeral (shoulder) joint
- Muscle tone regulation: Addresses spasm or weakness in the deltoid and supraspinatus
- Postural correction: Supports balance of anterior and posterior shoulder chain muscles
In TCM, it is also known to clear heat and dispel wind, which can contribute to upper limb dysfunction or stagnation.
Physiological Functions & Mechanisms
LI 15 lies within the deltoid region, overlapping the subdeltoid bursa and superficial fibers of the rotator cuff. Stimulation of this area can:
- Promote blood circulation and lymph drainage
- Modulate motor neuron excitability in the upper limb
- Activate proprioceptors responsible for shoulder joint awareness
This point also communicates with the Large Intestine meridian, which in TCM theory helps regulate skin, muscle, and defensive qi in the upper body.
Practitioner Insight
I often turn to LI 15 when working with clients experiencing early-stage frozen shoulder or repetitive strain from desk work. It can be slightly tender, but that’s usually a sign that it needs attention. When integrated into a routine with gentle stretching and breathwork, the results are often swift and restorative.
Safety & Contraindications
- Avoid excessive pressure if there is acute inflammation, bursitis, or joint infection.
- Exercise caution in elderly individuals with degenerative joint conditions.
- Do not apply to areas with recent surgical incisions or bruising.

As always, listen to your body and stop if discomfort arises.

Scientific Perspective
Functional studies support the role of LI 15 in improving range of motion and reducing shoulder pain through neuromodulation and improved regional circulation. In clinical acupuncture, it is a staple in treatment protocols for shoulder impingement syndrome, adhesive capsulitis, and rotator cuff dysfunction, with demonstrated improvements in pain scores and shoulder mechanics.
