The purpose of this study is to compare acupuncture plus a prescribed home exercise program versus a prescribed home exercise program alone to determine which has better outcomes at improving pain relief and physical function in adult patients with insertional Achilles tendinopathy.

The investigators want to compare a combination of two standard of care treatments (acupuncture plus a prescribed home exercise program) versus a single standard of care treatment (a prescribed home exercise program) to determine which has better outcomes with improving pain relief and physical function in patients with insertional Achilles tendinopathy. The investigators hypothesize that there will be a significant improvement in pain and functional outcomes, both acutely and over time, in the acupuncture plus a prescribed home exercise program group versus the group performing a prescribed home exercise program alone. The investigators will measure Achilles pain relief and physical function immediately prior to treatment (baseline), immediately after the initial treatment at day 1, 2 weeks, 4 weeks, 6 weeks, and 12 weeks using the Victorian Institute of Sports Assessment - Achilles Questionnaire (VISA-A). After 3 months, patients with continuing pain in the non-acupuncture arm will be given the option to crossover to the acupuncture arm of the study for an additional 12 weeks of treatment with the subject's concurrence.

Screening Visit (research-related):

• Obtain and document signed Informed Consent document and HIPAA Authorization.
• Review past medical history in Armed Forces Health Longitudinal Technology Application (AHLTA) to verify the inclusion/exclusion criteria including previous encounter, vital signs review, co-morbidities, demographics, and problems list.
• Record: Date of birth, age, gender, race, ethnicity, DoD ID number, name of standard of care medications (over-the-counter and prescription), current email address (to be used for scheduling), height (in inches), weight (in pounds),history of prior injury to the injured leg, and note any prior acupuncture received for Achilles tendinopathy.
• If the subject is an active duty member, the investigators will ask: Have you or are you currently on a fitness restriction for Achilles tendinopathy.

If so, what are/were the dates of the restriction?

• There are several standard of care treatments for Achilles tendinopathy which include physical therapy as well as a prescribed home exercise program. The investigators will standardize what patients in this study are receiving by having all subjects follow a standard home exercise program defined as the Insertional Achilles Tendinopathy Eccentric Training Protocol and have them discontinue any formal physical therapy or other therapies when entering this study. Regular physical activity such as exercise is allowed.

Randomization: Subjects will be randomized into 1 of 2 research treatment groups using block randomization with repeated measures:

• Group 1: Acupuncture (needles will be placed at BL 60, BL 61, KI 3, KI 4 with needles directed into the Achilles tendon. Needles inserted until a firm catch of the needle entering the tendon was appreciated. Energy (a small electrical current) is placed from KI 3(-) KI 4(+) and BL 61 (-) BL 60(+) at 30 Hz for 15min) plus the prescribed home exercise program
• Group 2: The prescribed home exercise program alone.

Visit 1-Day 1 (may be same day as screening visit) (research-related)::

• Subjects will be given a study diary to document the number of times they performed the Insertional Achilles Tendinopathy Eccentric Training Protocol.
• Subjects will be advised to complete exercises twice a day for three sets of 15 repetitions for 12 weeks.4
• Administer the Victorian Institute of Sports Assessment - Achilles Questionnaire (VISA-A)
• Document Morphine Equivalent Units (MEU) and over-the-counter and prescription medications used in the last 2 weeks.
• Self-reported pain severity pre-intervention (0 for no pain to 10 being the worst pain)
• Research treatment intervention according to their randomization group:

Group 1:

Subjects will be asked what their expectations are regarding acupuncture's effectiveness for Achilles tendinopathy.

The prescribed home exercise program will be reviewed. Acupuncture will be performed. Research coordinator will record the name of the investigator performing the acupuncture

Group 2:

The prescribed home exercise program will be reviewed. Self-reported pain severity post-intervention (0 for no pain to 10 being the worst pain)

Visit 2-Week 2 (research-related)::

• Subjects' study diaries will be reviewed and the number of times the Insertional Achilles Tendinopathy Eccentric Training Protocol was performed will be documented.

• Document Morphine Equivalent Units (MEU) and over-the-counter and prescription medications used since the last visit.
• Self-reported pain severity pre-intervention (0 for no pain to 10 being the worst pain)
• Research treatment intervention according to their randomization group:

Group 1:

The prescribed home exercise program will be reviewed. Acupuncture will be performed. Research coordinator will record the name of the investigator performing the acupuncture

Group 2:

The prescribed home exercise program will be reviewed. Self-reported pain severity post-intervention (0 for no pain to 10 being the worst pain)

Visit 3-Week 4 (research-related):

• Subjects' study diaries will be reviewed and the number of times the Insertional Achilles Tendinopathy Eccentric Training Protocol was performed will be documented.
