Efficacies of extracorporeal shockwave therapy and low-level laser therapy in patients with plantar fasciitis

BackgroundVarious conservative treatment methods can be administered in the early stages of plantar fasciitis (PF). The aim of the treatment is to enable the patient to return to the physical activity as soon as possible.AimIn this study it was aimed to compare efficacies of Extracorporeal Shockwave Therapy (ESWT) and Low-Level Laser Therapy (LLLT) on patients with PF.DesignA local prospective cross-sectional studySettingDepartment of Physical Medicine and Rehabilitation Outpatient Clinic of Sakarya University, Faculty of MedicinePopulationPatients aged 18–70 years, having ongoing heel pain for at least 3 months, and not using oral and/or parenteral corticosteroids in the last 6 months.MethodsA total of 40 patients with PF included in the current study. Visual Analog Scale (VAS), Roles and Maudsley Score (RMS), American Orthopedic Foot and Ankle Association Score (AOFAS) and Foot Function Index (FFI) questionnaire were performed for all patients. ESWT and LLLT groups comprised of 22 (55%) and 18 (45%) patients, respectively.ResultsWe found significant improvements in scores based on the VAS, RMS, AOFAS, FFI in patients with PF and it was sustained for 3 months (p = 0.001, for all scores). While decrease in scores based on the VAS and FFI in LLLT group was statistically more significant compared to ESWT group (p = 0.014, p = 0.013), there was statistically less significant decrease in scores on the AOFAS in LLLT group than that of ESWT group (p = 0.032).ConclusionsThe results of this study indicated significant improvements in terms of pain, functional status and daily life activities following the administration of either of the treatments. Furthermore, LLLT was found to be significantly more effective for alleviating pain than ESWT in the treatment of PF.     

Ultrasonographic evaluation at 6-month follow-up of plantar fasciitis after extracorporeal shock wave therapy

Introduction The aim of this study was to investigate the effect of extracorporeal shock wave therapy (ESWT) on the ultrasonographic appearance of chronically painful, proximal plantar fasciitis.Materials and methods Twenty-two patients with a unilateral proximal plantar fasciitis were prospectively enrolled after unsuccessful conservative treatment lasting 6 months. The contralateral plantar fascia was used as the control. ESWT (3×3000 shock waves/session of 0.2 mJ/mm²) was performed at weekly intervals. The thickness of the plantar fascia was measured ultrasonographically about 2 cm distal of the medial calcaneal tuberosity. Pain estimation on a visual analogue scale (VAS) and the comfortable walking time were recorded. No local anaesthesia was applied. Follow-up was done at 6, 12 and 24 weeks.Results Before ESWT, the plantar fasciitis side was ultrasonographically significantly thicker than the control side (p<0.05), whereas 6 months after ESWT, the thickness of the fascia was no longer significantly different. The decrease in thickness of the plantar fasciitis side was significant (p<0.05). Pain during activities of daily living decreased by 79% according to the VAS, and the comfortable walking time increased, both significantly (p<0.01). In patients with little pain (VAS<30), the thickness of the plantar fasciitis side was significantly less (p<0.01) compared with patients who still suffered more pain (VAS>30).Conclusion After ESWT, the thickness of the plantar fascia in patients with plantar fasciitis decreased, pain and walking time improved (all significantly).     

Dextrose prolotherapy versus radial extracorporeal shock wave therapy in the treatment of chronic plantar fasciitis: A randomized,controlled clinical trial

In the recent years, prolotherapy is increasingly being used in the field of musculoskeletal medicine. However, few studies have investigated its effectiveness in plantar fasciitis (PF). The purpose of this study was to compare the effectiveness of ultrasound-guided dextrose prolotherapy with radial extracorporeal shock wave therapy (ESWT) in the treatment of chronic PF. This randomized controlled trial was conducted on 59 patients with chronic PF. Patients were randomly assigned into two groups receiving three sessions of radial ESWT (29 patients) vs. two sessions of ultrasound-guided intrafascial 2 cc dextrose 20% injection (30 patients). The following outcome measures were assessed before and then six weeks and 12 weeks after the treatments: pain intensity by visual analog scale (VAS), daily life and exercise activities by Foot and Ankle Ability Measure (FAAM), and the plantar fascia thickness by ultrasonographic imaging. The VAS and FAAM scales showed significant improvements of pain and function in both study groups 6 weeks and 12 weeks after the treatments. A significant reduction was noted for plantar fascia thickness at these intervals (all p < .05). The inter-group comparison revealed that except for the FAAM-sport subscale which favored ESWT, the interaction effects of group and time were not significant for other outcome measures. Dextrose prolotherapy has comparable efficacy to radial ESWT in reducing pain, daily-life functional limitation, and plantar fascia thickness in patients with PF. No serious adverse effects were observed in either group.Level of evidenceLevel I, randomized controlled trial.     

A study to compare the efficacy of corticosteroid therapy with platelet-rich plasma therapy in recalcitrant plantar fasciitis: A preliminary report

BackgroundPlantar fasciitis is one of the commonest, and most frustrating, foot ailments seen in a regular orthopaedic clinic. There are a number of modalities available to treat this condition, of which corticosteroid injection is, perhaps, the most popular. However, recent years have seen an increased interest in the use of platelet-rich plasma (PRP) injections in various clinical situations such as plantar fasciitis.MethodsWe undertook a prospective non-randomized study to compare the efficacy of traditional corticosteroid injection (Steroid group) to PRP injection (PRP group), in a cohort of patients.ResultsWe studied both groups of patients before and after the injections using Visual Analogue Score (VAS), the Foot & Ankle Disability Index (FADI) and American Foot and Ankle Score (AFAS). Our study confirms that there is significant clinical improvement in PRP group at three months after the injection.ConclusionThe use of PRP injection can be an attractive alternative in the treatment of disabling, recalcitrant plantar fasciitis.Study designCohort study.Level of clinical evidenceLevel 3.     

The role of corticosteroid injections in treating plantar fasciitis: A systematic review and meta-analysis

BackgroundPlantar fasciitis is a recurrent cause of heel pain and is often treated by corticosteroid infections (CSI). The current study reviewed and analysed the role of CSI with platelet rich plasma (PRP), and CSI with extracorporeal shock wave therapy (EWST) for plantar fasciitis treatment.MethodsPubMed, Medline, Web of Science, Embase, Cochrane, and Google Scholar databases were searched for relevant studies. Preferred Reporting in Systematic Review & Meta-Analysis (PRISMA) guidelines were used to search relevant studies published from infinity to April 2021. The risk of bias was performed using Cochrane Collaboration’s tool. GRADE assessment was used for quality of evidence. Data analysis was performed with the use of R software and P < 0.05 was considered statistically significant. CSI was compared with PRP and EWST.ResultsEighteen studies comprising 1180 patients were included in this meta-analysis. When compared to PRP, CSI with lignocaine/lidocaine had significantly higher mean difference on visual analogue scale (VAS) pain scores at 3 months (0.62 [0.13; 1.12], P = 0.01) and 6 months (MD = 1.49 [0.22; 2.76], P = 0.02). At 6 months, VAS scores were higher in the CSI group than the ESWT group (MD = 0.8 [0.38; 1.22], P = 0.1). At 6 months, a significant reduction in the American Orthopaedic Foot and Ankle Score (AOFAS) was observed in the CSI group compared to PRP (MD = − 11.53 [− 16.62; − 6.43], P < 0.0001).ConclusionPatients suffering from plantar fasciitis, PRP achieved better VAS scores compared to CSI at 3 and 6-month follow-up. In addition, ESWT had better VAS score outcomes at 6 months compared to CSI. Regarding AOFAS score, PRP was more efficacious than CSI at 6 months of follow-up. Only through the development of high-quality, large-scale longitudinal studies, will the findings and conclusions of this meta-analysis be strengthened and influence our clinical practice in the treatment of plantar fasciitis.Level of clinical evidenceII.     

Extracorporeal shock wave therapy versus other therapeutic methods for chronic plantar fasciitis

BackgroundTo conduct a meta-analysis comparing the efficacy of general ESWT with that of other therapies and to assess its effectiveness in chronic plantar fasciitis.MethodsA literature search was performed in PubMed, Embase, Web of Science and the Cochrane Library for information from the earliest date of data collection to March 2018. Studies comparing the benefits and risks of extracorporeal shock wave therapy with those of other therapies for chronic plantar fasciitis were included. Statistical heterogeneity was quantitatively evaluated by a X² test with the significance set as P < 0.10 or I² > 50%.ResultsThirteen trials consisting of 1,185 patients were included (637 patients were treated with ESWT; 548 patients, with OT). The results showed that patients treated with ESWT had increased success or improvement rates, an increased modified Roles & Maudsley (RM) score, a reduction of pain scales, reduced return to work time, and fewer complications than patients treated with other therapy methods (P < 0.1).ConclusionsCompared with patients who received other therapies for chronic plantar fasciitis, patients treated with ESWT responded better, had less complications and showed a clear difference in efficacy between ESWT and other therapy in chronic plantar fasciitis.Level of Evidence: Level IV, therapeutic study.     

Magnetic resonance imaging findings of chronic plantar fasciitis before and after extracorporeal shock wave therapy

IntroductionThe objective of this study is to examine the relationships between treatment outcome and changes in magnetic resonance (MR) imaging findings after extracorporeal shock wave therapy (ESWT) for chronic plantar fasciitis.MethodsThe subjects were 23 feet of 23 patients of refractory plantar fasciitis. The mean age was 53.7 years. The thickness of the plantar fascia (PF) and findings of a high-signal intensity area (HSIA) inside the PF, edema around the PF, and bone marrow edema (BME) of the calcaneus were investigated on MR images. The Japanese Society for Surgery of the Foot (JSSF) ankle-hindfoot scale and a visual analogue scale (VAS) were used. Correlations between an improvement in symptoms and one in the MRI findings were analyzed.ResultsThe mean thickness of the PF was 4.4 ± 1.6 mm before ESWT and 4.6 ± 1.8 mm six months after ESWT. After ESWT, there was a decrease in the numbers of feet showing HSIA inside the PF from 15 to 6, in edema around the PF from 16 to 2, and in BME of the calcaneus from 11 to 4. Clinical outcomes improved with ESWT from 70.3 ± 5.5 to 88.6 ± 9.1 points (JSSF), 74.1 ± 25.3 to 28.5 ± 24.4 points (VAS), respectively. Improvements in symptoms according to the JSSF and VAS scores and improvement in edema around the PF on MR images showed a significant correlation.ConclusionsEdema around the PF improved significantly in association with an improvement in symptoms after ESWT.     

Similar effect of ultrasound-guided platelet-rich plasma versus platelet-poor plasma injections for chronic plantar fasciitis

BackgroundThere are conflicting reports regarding the therapeutic effect of platelet-rich plasma (PRP) versus autologous whole-blood (platelet poor plasma, PPP) injections for plantar fasciitis. Therefore, this study was conducted to compare the effectiveness of a single ultrasound (US)-guided PRP versus PPP injection in patients with chronic plantar fasciitis.Materials and methods36 patients were recruited with clinical and sonographic evidence of chronic (>6 months) plantar fasciitis, refractory to analgesics and physical therapy in a double-blinded, randomized, prospective study. The patients were randomly allocated into two groups with a sealed envelope method. Group A included 18 patients who underwent a single US-guided PRP injection and group B included another 18 patients who underwent PPP injection with the same technique. Follow-up was set at 3 and 6 months; no patient was lost to follow-up. Pain, function and satisfaction were assessed using visual analogue scales, and occurrence of complications.ResultsAll scores statistically significantly improved for both groups from baseline at the 3- and 6-month follow-up evaluation, without, however, any statistically significant differences between the two groups with respect to pain, function and satisfaction scores. Complications were not observed.ConclusionsA single US-guided PRP injection yields similar results with PPP injection in patients with chronic plantar fasciitis. Both treatments provide significant improvement at 3 and 6-month follow-up after the injection.     

Plantar fasciitis

INTRODUCTION

In this article we look at the aetiology of plantar fasciitis, the other common differentials for heel pain and the evidence available to support each of the major management options. We also review the literature and discuss the condition.

METHODS

A literature search was performed using PubMed and MEDLINE®. The following keywords were used, singly or in combination: ‘plantar fasciitis’, ‘plantar heel pain’, ‘heel spur’. To maximise the search, backward chaining of reference lists from retrieved papers was also undertaken.

FINDINGS

Plantar fasciitis is a common and often disabling condition. Because the natural history of plantar fasciitis is not understood, it is difficult to distinguish between those patients who recover spontaneously and those who respond to formal treatment. Surgical release of the plantar fascia is effective in the small proportion of patients who do not respond to conservative measures. New techniques such as endoscopic plantar release and extracorporeal shockwave therapy may have a role but the limited availability of equipment and skills means that most patients will continue to be treated by more traditional techniques.     

Extracorporeal shock wave therapy for plantar fasciitis. A double blind randomised controlled trial.

BACKGROUND: Extracorporeal shock wave therapy (ESWT) is an increasingly popular therapeutic approach in the management of a number of tendinopathies. Benefit has been shown in calcific tendinitis of the rotator cuff, but evidence for its use in non-calcific disorders is limited. AIMS: To perform a double blind randomised controlled trial of moderate dose shock wave therapy in plantar fasciitis. METHODS: Adults with plantar fasciitis for at least 3 months were randomised to receive either active treatment (0.12 mJ/mm(2)) or sham therapy, monthly for 3 months. Pain in the day, nocturnal pain and morning start-up pain were assessed at baseline, before each treatment and 1 and 3 months after completion of therapy. RESULTS: Eighty-eight subjects participated and no differences existed between the groups at baseline. At 3 months, 37% of the subjects in the ESWT group and 24% in the sham group showed a positive response (50% improvement from baseline) with respect to pain. Positive responses in night pain occurred in 41% and 31% in the ESWT and sham groups, respectively. Positive responses in start-up pain occurred in 37% and 36% in the ESWT and sham groups, respectively. Both groups showed significant improvement over the course of the study, but no statistically significant difference existed between the groups with respect to the changes were seen in any of the outcome measures over the 6-month period. CONCLUSIONS: There appears to be no treatment effect of moderate dose ESWT in subjects with plantar fasciitis. Efficacy may be highly dependent upon machine types and treatment protocols. Further research is needed to develop evidence based recommendation for the use ESWT in musculoskeletal complaints.     

Comparison of ultrasound-, palpation-, and scintigraphy-guided steroid injections in the treatment of plantar fasciitis

Background  The aim of the study was to compare the efficacies of steroid injections guided by scintigraphy, ultrasonography, and palpation in plantar fasciitis. Methods  A total of 35 heels of 27 patients were randomly assigned to three steroid injection groups: palpation-guided (pg), ultrasound-guided (ug), and scintigraphy-guided (sg). Patients were evaluated for pain intensity before the injections and at the last follow-up of 25.3 months with a 100-mm visual analog scale (VAS). Results  There were significant improvements in plantar fascia thickness, fat pad thickness, and VAS. Among the three groups of ug–pg, ug–sg, and pg–sg there were no statistically significant differences after treatment (P = 0.017, MWU = 36.5; P = 0.023, MWU = 29.5; and P = 0.006, MWU = 13, respectively). Conclusions  The ug, pg, and sg injections were effective in the conservative treatment of plantar fasciitis. We are of the opinion that steroid injections should be performed, preferably with palpation or ultrasonographic guidance.     

Thickness of plantar fascia is not predictive of functional outcome in plantar fasciitis treatment

Objective

The aim of this study was to define a quantitative parameter to indicate which cases of plantar fasciitis will benefit from local corticosteroid injection or ESWT and to compare the efficacy of two different treatment modalities.

Extracorporeal shockwave therapy (ESWT) ameliorates healing of tibial fracture non-union unresponsive to conventional therapy

Tibial non-unions are common cause of demanding revision surgeries and are associated with a significant impact on patients’ quality of life and health care costs. Extracorporeal shockwave therapy (ESWT) has been shown to improve osseous healing in vitro and in vivo. The main objective of present study was to evaluate the efficacy of ESWT in healing of tibial non-unions unresponsive to previous surgical and non-surgical measures. A retrospective multivariant analysis of a prospective open, single-centre, clinical trial of tibia non-union was conducted. 56 patients with 58 eligible fractures who met the FDA criteria were included. All patients received 3000–4000 impulses of electrohydraulic shockwaves at an energy flux density of 0.4 mJ/mm² (−6 dB). On average patients underwent 1.9 times (±1.3 SD) surgical interventions prior to ESWT displaying the rather negatively selected cohort and its limited therapy responsiveness. In 88.5% of patients receiving ESWT complete bone healing was observed after six months irrespective of underlying pathology. The multivariant analysis showed that time of application is important for therapy success. Patients achieving healing received ESWT earlier: mean number of days between last surgical intervention and ESWT (healed – 355.1 days ± 167.4 SD vs. not healed – 836.7 days ± 383.0 SD; p < 0.0001). ESWT proved to be a safe, effective and non-invasive treatment modality in tibial non-unions recalcitrant to standard therapies. The procedure is well tolerated, time-saving, lacking side effects, with potential to significantly decrease health care costs. Thus, in our view, ESWT should be considered the treatment of first choice in established tibial non-unions.

Repetitive low-energy shock wave application without local anesthesia is more efficient than repetitive low-energy shock wave application with local anesthesia in the treatment of chronic plantar fasciitis.

BACKGROUND: It remains unclear whether application of local anesthesia (LA) interferes with clinical efficacy of extracorporeal shock wave therapy (ESWT) for chronic plantar fasciitis. Aims: To evaluate the effect of local anesthesia on the clinical outcome after repetitive low-energy ESWT for chronic plantar fasciitis. METHODS: Eighty-six patients with chronic plantar fasciitis were randomly assigned to receive either low-energy ESWT without LA, given weekly for three weeks (Group I, n=45; 3 x 2000 pulses, total energy flux density per shock 0.09 mJ/mm2) or identical ESWT with LA (Group II, n=41). Primary outcome measure was: Reduction of pain from baseline to month 3 post-treatment in a pain numeric rating scale [0-10 points] during first steps in the morning, evaluated by an independent blinded observer. Calculations were based on intention-to-treat. RESULTS: No difference was found between the groups at baseline. At 3 months, the average pain score was 2.2+/-2.0 points for patients of Group I, and 4.1+/-1.5 points for patients of Group II. The mean between-group difference was 1.9 points (95% CI: [1.1-2.7 points]; P<.001). Significantly more patients of Group I achieved 50% reduction of pain compared to Group II (67% vs 29%, P<.001). CONCLUSION: ESWT as applied should be done without LA in patients suffering from chronic heel pain. LA applied prior treatment reduced the efficiency of low-energy ESWT.     

The effect of lengthening the gastrocnemius muscle in chronic therapy resistant plantar fasciitis

BackgroundThe aetiology of chronic therapy resistant plantar fasciitis (CTRPF) is multifactorial with more focus in recent times on the gastroc-soleus complex. This study evaluates the effect of lengthening the gastrocnemius muscle in CTRPF.MethodsAll patients with CRTPF complaints for at least one year underwent the same standard conservative treatment prior to surgery. 32 patients failed this treatment and underwent gastrocnemius recession. Silfverskiöld test, questionnaires and plantar pressure measurements were obtained at 5 visits.ResultsOne year follow up showed a significantly increase in dorsiflexion of the ankle (16 degrees), a decrease in VAS; 78 (SD: 19) to 20 (SD: 24) and significant improved functional scores. Plantar pressure measurements showed an increase of pressure under the medial proximal part of the midfoot and the 1 st metatarsal and a decrease under the hallux.ConclusionsA gastrocnemius recession results in a significant gain in dorsiflexion, altered loading of the foot and good clinical outcome in patients with CTRPF.Level of EvidenceLevel 2     

Comparing effectiveness of polydeoxyribonucleotide injection and corticosteroid injection in plantar fasciitis treatment: A prospective randomized clinical study

BackgroundThis study aimed to compare the efficacy and safety of polydeoxyribonucleotide (PDRN) injection and corticosteroid injection for plantar fasciitis.MethodsThis study included 44 patients with plantar fasciitis, randomly allocated to the PDRN and corticosteroid groups. Evaluation using the visual analogue scale (VAS) pain score and Manchester-Oxford foot questionnaire (MOXFQ) was conducted at baseline, 1, 2, 6 weeks and 6 months. The thickness and echogenicity of the plantar fascia in ultrasonography and complications were recorded.ResultsCorticosteroid injection elicited more pain relief than did PDRN injection at 2 (p = 0.010) and 6 weeks (p = 0.016); however, it showed no superiority at 6 months (p = 0.523). MOXFQ showed similar outcomes. The thickness and echogenicity did not differ between groups and no complications were reported in either group.ConclusionsWe demonstrated that PDRN injection could be an effective and safe option for plantar fasciitis and was comparable to corticosteroid injection after 6 months follow up.Level of evidenceII, comparative study.     

Extracorporeal shock wave therapy (ESWT) in patients with chronic proximal plantar fasciitis: a 2-year follow-up

The aim of this study was to compare the effect of extracorporeal shock wave therapy (ESWT) in patients with chronically painful proximal plantar fasciitis with a further conventional conservative treatment. Forty-seven patients (49 feet) with a previously unsuccessful nonsurgical treatment of at least 6 months were randomized to two groups. Heel cups had to be worn throughout the study. Group 1 (25 heels) was treated immediately with three sessions of ESWT (3000 shock waves/session of 0.2 mJ/mm2) at weekly intervals. The patients of group 2 (24 heels) continued nonsurgical treatment (iontophoresis with diclofenac and an oral nonsteroidal anti-inflammatory drug) for 12 weeks. After this period they were treated using the protocol of group 1. No significant difference of pain and walking time after further nonsurgical treatment (3 months) was seen in group 2. At 12 weeks after ESWT, the pain estimation on the visual analogue scale (VAS) for activities of daily living diminished significantly by 62.9% in group 1 and by 63.0% in group 2. The comfortable walking time had increased significantly in both groups. Two years after ESWT, pain during activities of daily living decreased by 94% in group 1 and by 90% in group 2 on the VAS and the comfortable walking time had increased significantly in both groups.     

Investigation of the relationship between the thickness of the plantar calcaneonavicular ligament and plantar fascia in patients with plantar fasciitis

BackgroundAlthough patients with plantar fasciitis show spring ligament laxity, the thickness of the spring ligament in patients with plantar fasciitis remains unclear. This study aimed to elucidate the morphological characteristics of the spring ligament in patients with plantar fasciitis based on an ultrasound imaging system (US).MethodsThirty feet of 30 patients (painful group) diagnosed with plantar fasciitis at our hospital and thirty feet of 30 healthy volunteers (healthy group) without plantar pain were investigated. The thicknesses of both the spring ligament and plantar fascia were assessed via a US statistical comparison of the spring ligament and plantar fascia thickness between the painful and healthy groups. This was performed using Welch’s t-test, and the significance level was set at p < 0.01. In addition, Pearson’s correlation coefficient was calculated to assess the correlation between the spring ligament and plantar fascia thickness in the two groups, and the significance level was set at p < 0.01.ResultsThe spring ligament thickness in the painful group was significantly lower than that in the healthy group (p < 0.001). The thickness of the plantar fascia in the painful group was significantly greater than that in the healthy group (p = 0.03). In addition, the correlation between the spring ligament and plantar fascia thickness was moderately negative (r = −0.42, p = 0.001). The thicker the plantar fascia in the subjects, the thinner was the spring ligament.ConclusionsThe thickness of the spring ligament in patients with plantar fasciitis decreased. The thinning of the spring ligament was negatively correlated with the thickening of the plantar fascia as per the US evaluation. Based on the spring ligament thinning determined via US evaluation, interventions such as insoles from an early stage could prevent the onset of plantar fasciitis.     

The treatment of intractable plantar fasciitis with platelet-rich plasma injection

BackgroundWhilst most cases of plantar fasciitis can be settled with existing conservative treatment, a few intractable cases can be difficult to resolve. New biologic treatments have been proposed for a variety of soft tissue problems.ObjectiveEvaluate the effectiveness of platelet rich plasma (PRP) in chronic cases of plantar fasciitis.Patients and methodsPatients with plantar fasciitis not responded to a minimum of 1 year standard conservative management were offered PRP therapy. Injections were performed in theatre as a day case. Roles–Maudsley (RM) scores, Visual Analogue Scores (VAS), AOFAS scores and ‘would have injection again’ were collated pre-operatively, three and six months.ResultsProspective data was collected of 50 heels (44 patients). At six month review, RM score improved from mean 4 to 2 (p < 0.001), VAS improved from 7.7 to 4.2 (p < 0.001) and AOFAS improved from 60.6 to 81.9 (p < 0.001). 28 patients (64%) were very satisfied and would have the injection again.No complications were reported.ConclusionIn these chronic cases, PRP produce an efficacy rate, approaching 2 out of every 3. The procedure was safe with no reported complications. The authors feel PRP may have some role in treatment, and merits further study with a prospective randomised trial.
