Rationales and Treatment Approaches Underpinning the Use of Acupuncture and Related Techniques for Plantar Heel Pain: A Critical Interpretive Synthesis

Background

Acupuncture shows promise as a treatment for plantar heel pain (PHP) or plantar fasciitis (PF), but data heterogeneity has undermined demonstration of efficacy. Recognising that acupuncture is a diverse field of practice, the aim of this study was to gain a broader, global perspective on the different approaches and rationales used in the application of acupuncture in PHP.

Methods

We built upon an earlier systematic review (which was limited by the necessity of a methodological focus on efficacy) using the critical interpretive synthesis (CIS) method to draw upon a wider international sample of 25 clinical sources, including case reports and case series. Multiple tracks of analysis led to an emergent synthesis.

Results

Findings are presented at three levels: primary (summarised data); secondary (patterns observed); and tertiary (emergent synthesis). Multiple treatments and rationales were documented but no single approach dominated. Notable contradictions emerged such as the application of moxibustion by some authors and ice by others. Synthesis of findings revealed a ‘patchwork’ of factors influencing the approaches taken.

Conclusions

The complexity of the field of acupuncture was illustrated through the ‘lens’ of PHP. The ‘patchwork’ metaphor provides a unifying framework for a previously divergent community of practice and research. Several directions for future research were identified, such as: importance of prior duration; existence of diagnostic subgroups; and how practitioners make clinical decisions and report their findings. CIS was found to provide visibility for multiple viewpoints in developing theory and modelling the processes of ‘real world’ practice by acupuncturists addressing the problem of PHP.

The Effectiveness of Acupuncture for Plantar Heel Pain: A Systematic Review

Introduction

Plantar heel pain (PHP) is a common complaint, yet there are no definitive guidelines for its treatment. Acupuncture is increasingly used by podiatrists, and there is a need for evidence to validate this practice. It is acknowledged that PHP and acupuncture are both complex phenomena.

Method

A systematic review (PROSPERO no. CRD42012001881) of the effectiveness of acupuncture for PHP is presented. Quality of the studies was assessed by independent assessors with reference to Quality Index (QI), ‘STandards for Reporting Interventions in Controlled Trials of Acupuncture’ (STRICTA) and ‘CONsolidated Standards Of Reporting Trials’ (CONSORT) criteria. Pooling of data, or even close comparison of studies, was not performed.

Results

Five randomised controlled trials and three non-randomised comparative studies were included. High quality studies report significant benefits. In one, acupuncture was associated with significant improvement in pain and function when combined with standard treatment (including non-steroidal anti-inflammatory drugs). In another, acupuncture point PC7 improved pain and pressure pain threshold significantly more than LI4. Other papers were of lower quality but suggest benefits from other acupuncture approaches.

Conclusions

There is evidence supporting the effectiveness of acupuncture for PHP. This is comparable to the evidence available for conventionally used interventions, such as stretching, night splints or dexamethasone. Therefore acupuncture should be considered in recommendations for the management of patients with PHP. Future research should recognise the complexity of PHP, of acupuncture and of the relationship between them, to explore the optimum use and integration of this approach. There is a need for more uniformity in carrying out and reporting such work and the use of STRICTA is recommended.
