Acupuncture for Heel Pain Syndrome
Clinical Research on Acupuncture at the Heel Pain Point for the Treatment of Heel Pain Syndrome
The main goal of this study is to determine whether acupuncture at the Heel Pain Point, a distal acupuncture point located on the palm, is an effective and safe treatment for heel pain syndrome. This randomized controlled trial compares Heel Pain Point acupuncture with manual therapy and sham acupuncture to evaluate both clinical efficacy and functional recovery. Specifically, the researchers aim to:
Measure Pain Relief: Evaluate whether Heel Pain Point acupuncture provides greater pain reduction than manual therapy and sham acupuncture using the Visual Analog Scale (VAS).
Assess Walking Function: Determine whether the intervention improves gait performance and foot function through three-dimensional gait analysis and the Maryland Foot Score.
Evaluate Immediate and Long-term Effects: Examine both the immediate analgesic effect after each treatment session and the sustained clinical benefits after completion of treatment and during follow-up.
Ensure Safety: Monitor adverse events and treatment-related complications throughout the study to confirm the safety of the intervention.
Target Population
The study is recruiting participants who meet the following criteria:
Age: Adults between 40 and 70 years.
Diagnosis: Individuals diagnosed with heel pain syndrome (primarily plantar fasciitis) according to established diagnostic criteria.
Disease Duration: Symptoms lasting less than two months, with no previous related treatment.
Typical Symptoms: Participants experiencing characteristic medial plantar heel pain, especially during the first steps after rest, localized tenderness at the plantar fascia insertion, limited ankle dorsiflexion, and abnormal foot posture.
Exclusions: Individuals with heel trauma, gout, osteomyelitis, inflammatory disorders, severe neurological deficits, contraindications to acupuncture, pregnancy, or serious systemic diseases (such as severe cardiovascular disease or uncontrolled diabetes).
Primary Research Endpoint
The primary endpoint is designed to determine whether Heel Pain Point acupuncture provides superior clinical benefit compared with manual therapy and sham acupuncture.
Pain Response Rate: The primary efficacy endpoint is the proportion of participants achieving at least a 50% reduction in VAS pain score from baseline after one complete treatment course.
Pain Intensity: Changes in Visual Analog Scale (VAS) scores will also be assessed to quantify pain reduction.
Objective Functional Recovery: Three-dimensional gait analysis will be used to evaluate improvements in gait speed, single-leg stability, foot progression angle, initial contact angle, push-off angle, and ground clearance.
Evaluation Timing: Primary outcomes will be assessed at baseline, immediately after treatment sessions (5 and 10 minutes), throughout the treatment period, after completion of the seven-session treatment course, and at 2-month and 6-month follow-up visits. These assessments are designed to capture both immediate analgesic effects and sustained clinical outcomes.

Kokeellinen: Acupuncture Group
Acupoint Selection: Contralateral point selection (i.e., the left heel pain point is selected for right heel pain, and vice versa). Heel Pain Point: Located on the palm, 0.8 cun distal to the Daling acupoint (PC7, located on the anterior aspect of the wrist, in the depression of the distal wrist crease, between the tendons of palmaris longus and flexor carpi radialis), toward the thenar eminence. Primary Needles: Hwato brand (0.25 × 40 mm, Suzhou, China). Primary Patch: Spunlace non-woven hollow patch (with cotton) (5 × 5 cm, ring diameter 2.3 cm, cotton diameter 1.5 cm, Yingrui Pharmaceuticals). |
The patient is instructed to sit with both hands fully exposed.
The practitioner applies the non-woven hollow patch over the skin.
Using a 0.3 × 40 mm sterile filiform needle, the practitioner pierces the hollow patch and inserts the needle obliquely downward at a 30°-45° angle to the skin, reaching a depth of 10-15 mm at the heel pain point.
An even reinforcing and reducing manipulation (Ping Bu Ping Xie) is applied with small-amplitude, uniform lifting, thrusting, and twirling.
Needle insertion stops upon the arrival of Deqi (sensation of soreness, numbness, distension, or pain).
The patient is instructed to move, rotate, and stomp the affected heel for 1-2 minutes.
After stomping, manipulation ceases; once the numbness in the foot subsides, the patient may stand or walk slowly to assess pain relief.
During the procedure, the patient should concentrate on the heel pain, and the operator will periodically monitor for any discomfort.
Needles are retained for approximately 15 minutes,

Huijausvertailija: Sham Acupuncture Control Group
Acupoint Selection: Contralateral point selection (i.e., the left heel pain point is selected for right heel pain, and vice versa). Heel Pain Point: Located on the palm, 0.8 cun distal to the Daling acupoint (PC7, located on the anterior aspect of the wrist, in the depression of the distal wrist crease, between the tendons of palmaris longus and flexor carpi radialis), toward the thenar eminence. Primary Needles: Hwato brand (0.25 × 40 mm, Suzhou, China). Primary Patch: Spunlace non-woven hollow patch (with cotton) (5 × 5 cm, ring diameter 2.3 cm, cotton diameter 1.5 cm, Yingrui Pharmaceuticals). |
Preparation is identical to the acupuncture group.
The filiform needle is passed through the lower part of the hollow patch and placed obliquely downward against the skin at a 30°-45° angle without penetrating it.
A secondary patch is then applied, with its adhesive backing peeled off, and secured smoothly and flatly against the patient's skin surface.No manual needle manipulation is performed.
The patient is instructed to remain seated quietly and refrain from any movement to prevent the needle tip from penetrating the skin, thereby avoiding any inadvertent therapeutic acupuncture effects.Needles are retained for approximately 15 minutes, and upon withdrawal, the puncture site is pressed with a dry cotton ball.
Treatment is administered every other day, with seven sessions constituting one therapeutic course

Active Comparator: Manual Therapy Group
Participants lie supine with the affected lower limb relaxed.
Manual therapy consists of: (1) thumb kneading and pressure applied to the painful plantar region for 5-10 minutes according to patient tolerance; (2) horizontal stretching by stabilizing the heel while dorsiflexing the ankle to stretch the Achilles tendon and triceps surae (5-10 repetitions, 30 s each); (3) straight-leg raise stretching with ankle dorsiflexion until gastrocnemius tension is achieved; and (4) clockwise and counterclockwise ankle rotation (3 circles each), repeated 3-4 times for 30 s. Treatments are administered every other day for seven sessions.
