10.1 Point Selection Strategies: Local, Adjacent, Distal, Theory-Based, and Mirroring
Key Takeaways
Combine local or adjacent points at the problem site with distal points on the channel that passes through it ('where the channel passes, its indications reach').
Theory-based selection draws on channel, Five Element (mother-son), Zang-Fu (Yuan, Back-Shu, Front-Mu), and Eight Principles logic, plus specific point categories.
Classic combinations include the Four Gates (LI 4 + LR 3), Yuan-Luo host-guest pairs, Front-Mu with Back-Shu, upper-lower, and front-back pairs.
Ashi points are tender points chosen by palpation, used especially for pain and Channel Sinew disorders.
Mirroring treats the opposite or corresponding area, such as right for left, elbow for knee, wrist for ankle, and front for back.
10.1 Point Selection Strategies: Local, Adjacent, Distal, Theory-Based, and Mirroring
Quick Answer: Point selection is 15% of the 2026 ACPL exam and underlies the 25% on treatment methods. Build a prescription in layers: local and adjacent points at the problem site, distal points on the channels that pass through it, and pattern points chosen by theory (channel, Five Element, Zang-Fu, Eight Principles) and by point category. Add combinations such as the Four Gates, Ashi (tender) points, and, when the area cannot be needled, mirroring (right for left, elbow for knee, front for back). The best answer on the exam is usually the one that addresses both the location and the pattern.
Local, Adjacent, and Distal Selection
The principle "where the channel passes, there its indications reach" (Jing Mai Suo Guo, Zhu Zhi Suo Ji) explains why a hand point treats the face.
| Type | Definition | Example: frontal headache from Stomach Heat |
|---|---|---|
| Local | At the site of the problem | Yintang, ST 8 |
| Adjacent | Near the site, on surrounding channels | GB 14, BL 2 |
| Distal | Far from the site, on the channel or a connected channel | LI 4 (Yangming above), ST 44 (Yangming below, clears Stomach Heat) |
Distal points are usually below the elbows and knees. In acute pain, a strong distal point stimulated while the patient gently moves the painful area often relieves pain quickly (for example, Yao Tong Dian for acute lumbar sprain or Luo Zhen for torticollis). In chronic conditions, local points address tissue changes while distal and pattern points address the root.
Selection by Theory
The 2026 outline lists the theories you may be asked to apply:
- Channel (Jing Luo): treat the affected channel, its paired interior-exterior channel (LI 4 for Lung problems), or the "same-name" channel of the other limb (Hand and Foot Yangming: LI 4 with ST 44).
- Five Element: tonify the mother point in deficiency and sedate the child point in excess (Section 9.1). Five Element style also addresses imbalances between elements, such as Wood overacting on Earth.
- Zang-Fu (organ): Yuan-Source points for the organ (KI 3 for the Kidney), Back-Shu and Front-Mu points (BL 18 and LR 14 for the Liver), and lower He-Sea points for the Fu organs (ST 37 for the Large Intestine).
- Eight Principles: the technique follows the principle. Excess is reduced, deficiency reinforced, Cold warmed with moxa, and Heat cleared, often by bleeding Jing-Well points, without moxa.
- Point categories: Five Transporting, Extra points, Hui (Influential), Confluent, Four Seas, Front-Mu, Back-Shu, Yuan, Luo, tonification and sedation, Five Element, and Xi-Cleft points (Chapter 9).
- Myofascial trigger points and motor points: Section 10.4.
Classic Point Combinations
| Combination | Example | Purpose |
|---|---|---|
| Four Gates (Si Guan) | LI 4 + LR 3 bilaterally | Move Qi and Blood, calm, relieve pain and spasm (avoid in pregnancy because of LI 4) |
| Yuan-Luo (host-guest) | LU 9 + LI 6 | Treat a primary organ and its paired channel |
| Front-Mu + Back-Shu | Ren 12 + BL 21 | Regulate an organ from front and back |
| Confluent pair | SP 4 + PC 6 | Open the Chong and Yin Wei vessels for the chest and epigastrium |
| Mother-son | LU 9 for Lung deficiency | Five Element tonification |
| Upper-lower | PC 6 + ST 36 | Harmonize the Stomach and calm nausea |
| Front-back | ST 25 + BL 25 | Regulate the Large Intestine |
| Entry-exit | LR 14 + LU 1 | Unblock the transfer between adjacent channels |
Worked Example
A patient has chronic right lateral knee pain that is worse in cold, damp weather, with loose stools and fatigue (Spleen Qi deficiency with Cold-Damp Bi).
- Local and adjacent: lateral Xiyan (ST 35), GB 34, and Ashi points around the knee.
- Distal on the affected channels: GB 41 (Shaoyang) and ST 41 (Yangming).
- Pattern points: ST 36 and SP 9 to strengthen the Spleen and resolve Dampness, and BL 20 at a later visit.
- Point category: GB 34 is also the Hui-Meeting point of the sinews.
- Method: even or reinforcing technique with moxibustion or a warm needle at ST 36 for Cold-Damp.
- Mirroring option: if the knee is too painful to needle, tender points around the left elbow (LI 11 and SJ 10 area).
Ashi Points
Ashi points, recorded by Sun Si-miao, are found by palpation: the patient says "Ah, yes!" when the tender spot is pressed. They have no fixed location. They are the main points for Channel Sinew disorders, acute sprains, and myofascial pain, and they often coincide with trigger points (Section 10.4). Palpate rather than guess: tenderness, nodules, taut bands, and temperature changes guide the needle.
Mirroring and Contralateral Needling
Mirroring selects a point in an area that corresponds to the affected area. It is useful when the painful site is injured, inflamed, casted, or too tender to needle.
| Mirror relationship | Example |
|---|---|
| Right for left (contralateral) | Left ankle sprain: needle the corresponding points on the right ankle |
| Upper for lower (elbow for knee, wrist for ankle) | Right knee pain: needle tender points around the left elbow |
| Front for back | Low back pain: points on the lower abdomen at the same level |
Classical texts describe contralateral needling as Ju Ci (needling the opposite primary channel) and Miu Ci (needling the opposite Luo vessel), discussed in Su Wen Chapter 63. Have the patient gently move the affected area while the mirror points are stimulated.
Putting a Prescription Together
A balanced prescription usually has 6-12 needles (fewer for children, older adults, and weak patients) and includes:
- One or two principal points that treat the main pattern.
- Supporting points that reinforce the principle or treat the root.
- Local or symptomatic points for the chief complaint.
- Bilateral needling for organ patterns; unilateral or contralateral needling for one-sided channel problems.
A patient has a frontal headache with a red face, thirst, foul breath, and constipation from Stomach Heat. Which combination best pairs a local point with distal points that address both the location and the pattern?
GB 20 with BL 60 and SI 3
Taiyang with SJ 5 and GB 41
Du 20 with LR 3 and KI 1
Yintang with LI 4 and ST 44
A patient's right ankle is too swollen and bruised to needle after a sprain. Which approach applies the mirroring concept?
Needle the corresponding points around the left ankle while the patient moves the right ankle
Needle only local points around the right knee above the injured ankle, with strong stimulation
Use the Four Gates alone, because they treat pain anywhere in the body
Wait until the swelling resolves completely before any treatment
How are Ashi points located?
By proportional cun measurement from fixed bony landmarks
By palpating for tender or reactive spots, which have no fixed location
Only at Jing-Well points at the nail corners of the affected channel
By choosing the Horary point of the affected channel at its peak time of day
A practitioner treats a patient's Large Intestine disorder with ST 25 (Tianshu) and BL 25 (Dachangshu). Which combination principle is being used?
Yuan-Luo host-guest pairing
Front-Mu and Back-Shu (front-back) pairing
Mother-son Five Element tonification
Four Gates
