Corticosteroid injection for plantar heel pain: a systematic review and meta-analysis.

BACKGROUND: Corticosteroid injection is frequently used for plantar heel pain (plantar fasciitis), although there is limited high-quality evidence to support this treatment. Therefore, this study reviewed randomised trials to estimate the effectiveness of corticosteroid injection for plantar heel pain. METHODS: A systematic review and meta-analysis of randomised trials that compared corticosteroid injection to any comparator. Primary outcomes were pain and function, categorised as short (0 to 6 weeks), medium (7 to 12 weeks) or longer term (13 to 52 weeks). RESULTS: A total of 47 trials (2989 participants) were included. For reducing pain in the short term, corticosteroid injection was more effective than autologous blood injection (SMD -0.56; 95% CI, - 0.86 to - 0.26) and foot orthoses (SMD -0.91; 95% CI, - 1.69 to - 0.13). There were no significant findings in the medium term. In the longer term, corticosteroid injection was less effective than dry needling (SMD 1.45; 95% CI, 0.70 to 2.19) and platelet-rich plasma injection (SMD 0.61; 95% CI, 0.16 to 1.06). Notably, corticosteroid injection was found to have similar effectiveness to placebo injection for reducing pain in the short (SMD -0.98; 95% CI, - 2.06, 0.11) and medium terms (SMD -0.86; 95% CI, - 1.90 to 0.19). For improving function, corticosteroid injection was more effective than physical therapy in the short term (SMD -0.69; 95% CI, - 1.31 to - 0.07). When trials considered to have high risk of bias were excluded, there were no significant findings. CONCLUSIONS: Based on the findings of this review, corticosteroid injection is more effective than some comparators for the reduction of pain and the improvement of function in people with plantar heel pain. However, corticosteroid injection is not more effective than placebo injection for reducing pain or improving function. Further trials that are of low risk of bias will strengthen this evidence.

Effectiveness of trigger point dry needling for plantar heel pain: a randomized controlled trial.

BACKGROUND: Plantar heel pain can be managed with dry needling of myofascial trigger points; however, there is only poor-quality evidence supporting its use. OBJECTIVE: The purpose of this study was to evaluate the effectiveness of dry needling for plantar heel pain. DESIGN: The study was a parallel-group, participant-blinded, randomized controlled trial. SETTING: The study was conducted in a university health sciences clinic. PATIENTS: Study participants were 84 patients with plantar heel pain of at least 1 month's duration. INTERVENTION: Participants were randomly assigned to receive real or sham trigger point dry needling. The intervention consisted of 1 treatment per week for 6 weeks. Participants were followed for 12 weeks. MEASUREMENTS: Primary outcome measures included first-step pain, as measured with a visual analog scale (VAS), and foot pain, as measured with the pain subscale of the Foot Health Status Questionnaire (FHSQ). The primary end point for predicting the effectiveness of dry needling for plantar heel pain was 6 weeks. RESULTS: At the primary end point, significant effects favored real dry needling over sham dry needling for pain (adjusted mean difference: VAS first-step pain=-14.4 mm, 95% confidence interval [95% CI]=-23.5 to -5.2; FHSQ foot pain=10.0 points, 95% CI=1.0 to 19.1), although the between-group difference was lower than the minimal important difference. The number needed to treat at 6 weeks was 4 (95% CI=2 to 12). The frequency of minor transitory adverse events was significantly greater in the real dry needling group (70 real dry needling appointments [32%] compared with only 1 sham dry needling appointment [<1%]). LIMITATIONS: It was not possible to blind the therapist. CONCLUSION: Dry needling provided statistically significant reductions in plantar heel pain, but the magnitude of this effect should be considered against the frequency of minor transitory adverse events.

Consensus for dry needling for plantar heel pain (plantar fasciitis): a modified Delphi study.

HYPOTHESIS: Plantar heel pain (plantar fasciitis) is a common and disabling condition. A variety of treatment options are available to patients with plantar heel, however the evidence for these treatments is generally weak and the best way to manage plantar heel pain remains unclear. Trigger point dry needling is increasingly used as an adjunct therapy for musculoskeletal pain. In patients with plantar heel pain this technique is thought to improve muscle activation patterns, increase joint range of motion and alleviate pain. However, there have been no randomised controlled trials that have evaluated the effectiveness of dry needling for plantar heel pain. METHODS: In order to develop a treatment protocol to evaluate the effectiveness of dry needling for plantar heel pain we conducted a three stage modified Delphi process using a web-based survey technique. Over a series of three iterations, 30 experts (participants) worldwide indicated their level of agreement on specific issues relating to the use of dry needling for plantar heel pain including their treatment rationale, needling details and treatment regimen. Consensus for a dry needling protocol for plantar heel pain was achieved when >60% of participants (IQR ≤ 1.0 category on 5-point Likert scale) agreed the protocol was adequate. RESULTS: The response rate was 75% (n=30), 100% (n=30) and 93% (n=28) in the first, second and third rounds respectively. Round 1 helped generate a list of 10 items that were deemed important for developing a dry needling protocol for plantar heel pain. These 10 items were subsequently presented in Round 2. Of these, 5 of the 10 items met the criteria to be included in a dry needling protocol for plantar heel pain that was presented in the final round, Round 3. Items that did not meet the criteria were either removed or amended and then presented in Round 3. In the final round, 93% of participants (IQR range = 1) agreed the proposed dry needling protocol for plantar heel pain was adequate. The protocol can now be used in future research projects designed to evaluate the effectiveness of dry needling for plantar heel pain.

Effectiveness of trigger point dry needling for plantar heel pain: study protocol for a randomised controlled trial.

BACKGROUND: Plantar heel pain (plantar fasciitis) is a common and disabling condition, which has a detrimental impact on health-related quality of life. Despite the high prevalence of plantar heel pain, the optimal treatment for this disorder remains unclear. Consequently, an alternative therapy such as dry needling is increasingly being used as an adjunctive treatment by health practitioners. Only two trials have investigated the effectiveness of dry needling for plantar heel pain, however both trials were of a low methodological quality. This manuscript describes the design of a randomised controlled trial to evaluate the effectiveness of dry needling for plantar heel pain. METHODS: Eighty community-dwelling men and woman aged over 18 years with plantar heel pain (who satisfy the inclusion and exclusion criteria) will be recruited. Eligible participants with plantar heel pain will be randomised to receive either one of two interventions, (i) real dry needling or (ii) sham dry needling. The protocol (including needling details and treatment regimen) was formulated by general consensus (using the Delphi research method) using 30 experts worldwide that commonly use dry needling for plantar heel pain. Primary outcome measures will be the pain subscale of the Foot Health Status Questionnaire and "first step" pain as measured on a visual analogue scale. The secondary outcome measures will be health related quality of life (assessed using the Short Form-36 questionnaire - Version Two) and depression, anxiety and stress (assessed using the Depression, Anxiety and Stress Scale - short version). Primary outcome measures will be performed at baseline, 2, 4, 6 and 12 weeks and secondary outcome measures will be performed at baseline, 6 and 12 weeks. Data will be analysed using the intention to treat principle. CONCLUSION: This study is the first randomised controlled trial to evaluate the effectiveness of dry needling for plantar heel pain. The trial will be reported in accordance with the Consolidated Standards of Reporting Trials and the Standards for Reporting Interventions in Clinical Trials of Acupuncture guidelines. The findings from this trial will provide evidence for the effectiveness of trigger point dry needling for plantar heel pain. TRIAL REGISTRATION: Australian New Zealand 'Clinical Trials Registry'.

Effectiveness of dry needling and injections of myofascial trigger points associated with plantar heel pain: a systematic review.

BACKGROUND: Plantar heel pain (plantar fasciitis) is one of the most common musculoskeletal pathologies of the foot. Plantar heel pain can be managed with dry needling and/or injection of myofascial trigger points (MTrPs) however the evidence for its effectiveness is uncertain. Therefore, we aimed to systematically review the current evidence for the effectiveness of dry needling and/or injections of MTrPs associated with plantar heel pain. METHODS: We searched specific electronic databases (MEDLINE, EMBASE, AMED, CINAHL, SPORTDiscus and AMI) in April 2010 to identify randomised and non-randomised trials. We included trials where participants diagnosed with plantar heel pain were treated with dry needling and/or injections (local anaesthetics, steroids, Botulinum toxin A and saline) alone or in combination with acupuncture. Outcome measures that focussed on pain and function were extracted from the data. Trials were assessed for quality using the Quality Index tool. RESULTS: Three quasi-experimental trials matched the inclusion criteria: two trials found a reduction in pain for the use of trigger point dry needling when combined with acupuncture and the third found a reduction in pain using 1% lidocaine injections when combined with physical therapy. However, the methodological quality of the three trials was poor, with Quality Index scores ranging form 7 to 12 out of a possible score of 27. A meta-analysis was not conducted because substantial heterogeneity was present between trials. CONCLUSIONS: There is limited evidence for the effectiveness of dry needling and/or injections of MTrPs associated with plantar heel pain. However, the poor quality and heterogeneous nature of the included studies precludes definitive conclusions being made. Importantly, this review highlights the need for future trials to use rigorous randomised controlled methodology with measures such as blinding to reduce bias. We also recommend that such trials adhere to the Standards for Reporting Interventions in Controlled Trials of Acupuncture (STRICTA) to ensure transparency.
