How effective is acupuncture for reducing pain due to plantar fasciitis?

Plantar fasciitis is a very common condition that affects millions of people annually, characterized by intense heel pain that typically worsens in the morning upon taking the first steps. This condition occurs when there is inflammation or microtears in the plantar fascia, a fibrous structure that connects the heel to the toes and provides support to the arch of the foot. Although various conventional treatments are available, such as physical therapy, orthotics, anti-inflammatory medications, and even surgery in severe cases, many patients seek complementary alternatives due to the persistent nature of the pain. Acupuncture has gained increasing interest as a therapeutic option, especially considering that local studies show that a significant proportion of patients with chronic pain use this ancient Chinese practice.

This scientific study aimed to systematically evaluate the efficacy of acupuncture in relieving pain caused by plantar fasciitis. To this end, the researchers conducted a systematic review of the scientific literature, specifically searching for randomized controlled trials comparing acupuncture with standard treatments or testing true acupuncture versus sham procedures. The search was conducted in the main medical databases, including PubMed and the Cochrane Library, using specific terms related to acupuncture and plantar fasciitis. The inclusion criteria were rigorous, selecting only studies that used traditional dry-needle acupuncture or electroacupuncture, excluding other modalities such as laser acupuncture.

The methodological quality of each study was assessed using the Delphi list, an instrument that analyzes nine important criteria to determine the reliability of results.

The analysis identified four relevant studies that met the established criteria, involving a total of 144 patients with plantar fasciitis. Three studies compared acupuncture with conventional treatments, while one compared true acupuncture with sham acupuncture at different body points. The results were consistently positive, showing that acupuncture provided significant pain reduction measured through standardized scales such as the visual analog scale and the plantar fasciitis-specific pain and disability scale. The benefits were observed primarily between four and eight weeks of treatment, demonstrating that acupuncture can offer faster relief compared with conventional treatment alone.

It is important to note that side effects were minimal, mostly limited to small bruises or local swelling at the needle insertion site, and some patients reported mild pain after the procedure.

The clinical implications of these findings are promising for both patients and healthcare professionals. For people suffering from plantar fasciitis, acupuncture represents a safe and potentially effective therapeutic option, especially when conventional treatments do not provide adequate relief or when avoiding long-term anti-inflammatory medications is desired. Acupuncture can be particularly valuable as part of an integrated treatment plan, combining it with physical therapy, stretching exercises, and other conservative measures. For healthcare professionals, these results suggest that acupuncture should be considered a legitimate therapeutic option, especially given its favorable safety profile.

The fact that benefits appear relatively quickly, between one and two months of treatment, is also clinically relevant, as it offers hope of relief within a reasonable time frame for patients who often live with debilitating chronic pain.

However, it is essential to recognize the important limitations of this research. The number of available studies is still small, and each involved relatively few participants, ranging from 23 to 53 people. The methods of applying acupuncture varied considerably between studies, some using simple needles and others electroacupuncture, with differences in the specific points treated and session duration. Only one study followed patients for a longer six-month period, and it showed that the benefits of acupuncture did not remain superior to standard treatment in the long term.

This suggests that, although acupuncture may be effective for initial symptom relief, maintenance treatment or combination with other therapies may be necessary for lasting benefits. In addition, most studies could not implement adequate blinding of participants, which may have influenced the results due to positive expectations regarding acupuncture treatment. Therefore, although the results are encouraging, more studies with larger samples, more standardized methodology, and longer follow-up are needed to definitively establish the role of acupuncture in the treatment of plantar fasciitis and better guide patients and professionals on their realistic expectations regarding this complementary therapy.
