Futu (ST32) Acupoint — Exact Location and Acupressure Technique Guide for Knee Pain Relief

What is the Futu Acupoint?

Futu (ST32) is the 32nd acupoint on the Stomach Meridian (足陽明胃經), which has 44 acupoints total. In traditional Chinese medicine, it has been used for over 5,000 years as a major acupoint for treating lower body pain.

The name “Futu” refers to the knee area, and as the name suggests, it directly affects knee and surrounding pain. The Stomach Meridian is a long channel that runs from the toes to the face, so stimulating Futu also affects whole-body circulation.

Exact Location of Futu — 3 Methods to Find It

Futu’s effectiveness depends on locating it precisely. It may be difficult at first, but you can find it by following one of these 3 methods.

Method 1: Measuring by Finger Width (Easiest)

1. Find the upper edge of the kneecap.
2. From that point, move upward by the width of 3-4 fingers (approximately 5-6 cm).
3. Futu is located in the center of the front of the thigh, on the rectus femoris muscle, where you’ll find a slight depression.

Method 2: Traditional Chinese Medicine Measurement (18 cm)

1. Start from the outer edge of the kneecap.
2. Move upward vertically exactly 18 cm (6 cun).
3. It is located in the muscle layer at the front of the thigh.

Method 3: Identifying by Depression (Most Accurate)

Slowly press and move your fingers across the front of the thigh about 5-6 cm above the knee. Futu is where you feel a slight depression compared to surrounding areas. When you press this point, a cool, refreshing sensation spreads down to the calf.

Futu Acupressure Technique — 4-Step Execution Guide

Proper technique is essential for Futu. Press gradually, as pressing too hard can cause muscle damage.

Step 1: Preparation Posture

Sit comfortably with your legs extended or lie down. The most comfortable position for acupressure is with your knee slightly bent.

Step 2: Hand Position Setup

Place the pad of your thumb (the textured area at the tip) perpendicular to Futu. Support the area around Futu with your other fingers for stability.

Step 3: Gradual Pressure Increase

For the first 10 seconds, apply light pressure; for the next 10 seconds, apply medium pressure; and for the final 10 seconds, gradually increase to a level of “soreness that is tolerable” (酸脹感). Do not apply heavy pressure all at once.

Step 4: Acupressure Technique

You can apply acupressure using two methods:

• Vertical Pressing: Repeatedly press your finger up and down, pressing every 1 second.
• Circular Pressing: Move your finger in small circles, clockwise and counterclockwise.

Continue for 1-3 minutes per session. After acupressure, within 5 minutes you’ll feel warmth spreading, indicating improved blood circulation.

Optimal Timing and Frequency of Acupressure

To maximize effectiveness, consistent timing and frequency are important. Here are the recommended methods.

Recommended Frequency: 2-3 Times Daily

• Morning (7-8 AM): Once after waking, either before getting out of bed or while sitting
• Evening (6-8 PM): 1-2 times; applying acupressure in the evening increases recovery during sleep
• After Exercise: An additional session is possible when fatigued

Duration and Changes

• 3-7 days: You’ll feel warmth and cooling sensations immediately after acupressure. Knee stiffness is relieved on the same day.
• 1-2 weeks: Knee pain gradually decreases. Discomfort when descending stairs diminishes.
• 3-4 weeks: You’ll feel little to no pain during daily activities. Consistent maintenance is important.

You won’t notice significant effects unless you practice consistently for at least 3 weeks. Daily practice for the first 2 weeks is recommended.

Important Precautions to Check Before Acupressure

Situations to Avoid

• After Meals: Wait at least 30 minutes before acupressure. Stimulation during digestion can cause abdominal discomfort.
• On an Empty Stomach: Avoid when very hungry. Low blood sugar can cause dizziness.
• During Fever: Avoid when feverish due to cold or inflammation.
• Extreme Fatigue: Proceed only after adequate rest.
• After Acute Injury: Avoid if you’ve had a knee injury within the last 24 hours.

Skin Condition Check

Avoid acupressure if the Futu area has wounds, rashes, or severe inflammation. Wait until your skin is completely healed.

Contraindications for Special Populations

Precautions After Acupressure

• Avoid Cold Air: Avoid air conditioning or cold wind exposure for 30 minutes after acupressure.
• Avoid Strenuous Exercise: Avoid vigorous exercise within 1 hour after acupressure.
• If Symptoms Worsen: Stop immediately and consult a healthcare professional if pain intensifies or new symptoms develop after acupressure.

When Futu Alone Is Not Enough — Combining Other Acupoints

While Futu is effective, it cannot resolve all causes of knee pain. In the following cases, combining other acupoints will be more effective.

Pain Around the Knee: Additional Acupoint Combinations

Combining Futu (above the knee) with other acupoints around the knee joint can produce faster results. If you suspect knee arthritis, consult a TCM practitioner to identify additional acupoints.

Full Leg Numbness: Adding Calf Acupoints

If you experience severe leg numbness, stimulating calf acupoints together with Futu is effective. Since the Stomach Meridian runs through the entire leg, stimulating multiple points is more beneficial.

When Both Back and Legs Hurt: Understanding the Entire Stomach Meridian

If you experience chronic pain in both the back and legs, you need to understand the entire Stomach Meridian, not just Futu. Learning about the major acupoints on the Stomach Meridian enables more systematic self-care.
