Radial extracorporeal shock wave therapy (r-ESWT) is accepted as one of the most effective treatment modalities for plantar fasciitis (PF). Also kinesio taping (KT) applicationis effective for the treatment of PF. However, there is not enough evidence about the effectiveness of the combination of these two modalities in the treatment of PF. This prospective randomized clinical trial was planned to investigate the acute effects of KT application in addition to r-ESWT application on pain, foot function and flexibility. The study was performed on 42 patients with unilateral PF, that were randomly assigned into two groups receiving four sessions of either r-ESWT or r-ESWT+KT treatment once per week. All patients performed home exercises. Patients' pain levels were evaluated via the Visual Analogue Scale (VAS), and foot function via the Foot Function Index (FFI). Flexibility was evaluated through gastro-soleus and plantar fascia flexibility tests. The evaluations were done before and one week after the final treatment. Two Way Analysis of Variance with Repeated Measures and Generalized Estimating Equations (GEE) methods were used in statistical analyses. As a result, rest pain and activity pain decreased in both groups and there is no differences between the groups (respectively p: 0,831; p: 0.331). FFI pain and disability subscores decreased and were also similar between the groups (respectively p: 0.304; p: 0.978). FFI activity limitation subscore decreased in the r-ESWT group more than r-ESWT+KT group (p: 0.002). Night pain, gastro-soleus and plantar fascia flexibility did not change in both goups (respectively p: 0.713; p: 0.413; p: 0.475). Adding KT to r-ESWT application did not create an additional pain relieving effect, on the contrary, resulted in less improvement in activity limitation. This may be related to the fact that KT application to the sole and heel region creates a hard surface on the heel. r-ESWT application may be more beneficial in PF where activity limitation are prominent.

Purpose Plantar fasciitis is a frequent and painful condition with a lifetime incidence of 10%. Good results have been reported for operative treatment of plantar fasciitis refractory to non-surgical interventions in uncontrolled studies. The aim of this study was to compare the results of operative treatment (endoscopic debridement, removal of the heel spur and partial resection of the plantar fascia) with those of a controlled and supervised non-operative rehabilitation program. Methods Thirty consecutive patients with plantar fasciitis during more than 3 months were randomized to either (1) non-operative treatment with corticosteroid injections and a controlled strength training program or (2) an endoscopic 2-incision operation with partial fasciotomy and heel spur removal followed by the same strength training program. Patients were evaluated at entry and 3, 6, 12 and 24 months post-operatively with the foot function index (FFI) and pain score during activity on a 100 mm VAS scale (VAS activity). FFI at 6 and 12 months was defined a priori as primary endpoint. Results Both groups improved significantly over time. The FFI score was significantly better in the operated group compared to the non-surgically treated group 12 months post-operatively ( p  = 0.033), at 24 months this was, however, not significant ( p  = 0.06). VAS activity at 24 months was significantly ( p  = 0.001) in favor of the operative group. More patients returned to running and jumping in the operative group ( p  = 0.04). Conclusion This randomized controlled trial found significant and clinically relevant superior results for the operative treatment of plantar fasciitis as measured by Foot Function Index at 1 year and by VAS activity at 2-year follow-up when compared to the results of a supervised rehabilitation program. Level of evidence I.

Pes planus (flatfoot) is a common deformity characterized by the midfoot arch collapses during walking. As the midfoot is responsible for shock absorption, persons with flatfoot experience increased risk of injuries such as thumb valgus, tendinitis, plantar fasciitis, metatarsal pain, knee pain, lower-back pain with prolonged uphill, downhill, and level walking, depriving them of the physical and mental health benefits of walking as an exercise. Fifteen female college students with flatfoot were recruited. A wireless plantar-pressure system was used to measure the stance time, cadence, plantar pressure, and contact area. Parameters were compared between wearing flat and arch-support insoles using a two-way repeated measures ANOVA with on an incline, decline, and level surface, respectively. The significance level [alpha] was set to 0.05. The effect size (ES) was calculated as a measure of the practical relevance of the significance using Cohen's d. On the level surface, the stance time in the arch-support insole was significantly shorter than in the flat insole (p<0.05; ES = 0.48). The peak pressure of the big toe in the arch-support insole was significantly greater than in the flat insole on the uphill (p<0.05; ES = 0.53) and level surfaces (p<0.05; ES = 0.71). The peak pressure of the metatarsals 2-4 and the contact area of the midfoot in the arch-support insole were significantly greater than in the flat insole on all surfaces (all p< 0.05). These results imply that wearing an arch-support insole provides benefits in the shortened stance time and generation of propulsion force to the big toe while walking on uphill and level surfaces and to the metatarsals 2-4 while walking on the level surface. More evenly distributed contact areas across the midfoot may help absorb shock during uphill, downhill and level walking.

Hallux valgus is a foot pathological condition showing a lateral deviation of the first phalange and medial deviation of the first metatarsal. The purpose of the current study was to evaluate a longitudinal effect of minimalist footwear running protocol for a mild/moderate hallux valgus patient. The computer tomography (CT) images from a male hallux valgus (HV) patient were respectively scanned pre and post 12-week minimalist footwear running intervention. The pre and post -intervention foot finite element (FE) models were developed from the foot three-dimensional geometries manually segmented via the MIMICS 21.0. The post-process with SolidWorks 2019 was conducted for model assembly, consisting of 24 bones, 22 cartilages, five plantar fascia, and lumped encapsulated soft tissue. The foot FE models were solved in ANSYS Workbench 2020 R1 package. The FE models were validated against the plantar pressure (pre: 0.146 MPa vs 0.155 MPa, and post: 0.156 MPa vs 0.17 MPa) and vertical displacements (pre: 2.6 mm vs 2.4 ± 0.4 mm, and post 1.1 mm vs 1.3 ± 0.4 mm) of navicular measured from experiments. The first metatarsophalangeal joint showed varus realignment and the von Mises stress in the first metatarsal and the second metatarsal decreased 72.1% and 51.2% compared with pre-intervention (M1: 4.41 MPa and M2: 4.18 MPa). This framework investigated the shape adjustment and functional recovery in the mild/moderate HV deformity, which may provide references and implications for future studies with a larger cohort.

Foot abnormality has become a public health concern. Early detection of pathological soft tissue is therefore an important preventive measure, especially in older people who generally have a higher risk of foot pathology. However, the interpretation of plantar tissue stiffness data – whether to normalize the data or to separate the data on the basis of sex– remains questionable. The objective of this study was to assess the influence of sex and physical attributes such as body mass (BM) and body mass index (BMI) on plantar soft-tissue stiffness, and to evaluate whether it is necessary to isolate the differences in sex, BM and BMI in the data analysis. One hundred healthy subjects in their 60s were recruited for the experiment. Localized force response was obtained underneath the second metatarsal head (MTH) pad at three different dorsiflexion angles of 0°, 20°, 40° and the hallux and heel at 0°. No significant relationship was found between the independent variables and plantar stiffness. From the experimental results, it can be deduced that BM and BMI are weakly associated with plantar tissue stiffness, and that there is no significant difference in stiffness between male and female participants. No difference was found between left and right foot measurements. This suggests that normalizing of plantar tissue stiffness by BM and BMI is not necessary in healthy people in their 60s. The data can be pooled and treated equally regardless of sex.

The number of systematic review and meta-analyses on plantar fasciitis is expanding. The purpose of this review was to provide a comprehensive summary of reviews on the topic pertaining to plantar fasciitis, identify any conflicting and inconsistent results, and propose future research direction. A qualitative review of all systematic reviews and meta-analyses related to plantar fasciitis up to February 2021 was performed using PubMed, Embase, Web of Science, and the Cochrane Database. A total of 1052 articles were initially identified and 96 met the inclusion criteria. Included articles were summarized and divided into the following topics: epidemiology, diagnosis, and treatment. While the majority of reviews had high level of heterogeneity and included a small number of studies, there was general consensus on certain topics, such as BMI as a risk factor for plantar fasciitis and extracorporeal shockwave therapy as an effective mode of therapy. A qualitative summary of systematic reviews and meta-analyses published on plantar fasciitis provides a single source of updated information for clinicians. Evidence on topics such as the epidemiology, exercise therapy, or cost-effectiveness of treatment options for plantar fasciitis are lacking and warrant future research.

This pilot study primarily aimed to detect the adherence as well as the effect size required to estimate the actual sample size needed for a larger scale study to compare and evaluate the effectiveness of two extracorporeal shock wave therapy (ESWT) protocols along, with a physical therapy program in reducing pain and improving function among patients suffering from plantar fasciitis. The study also aimed to report the effects of the ESWT protocols used on pain and function. A total of 26 participants took part in the study, including 17 females and 9 males. The average age of the participants was 34 years with a body mass index (BMI) of 23 kg/m2. Participants were divided into three equal groups; Group A received ESWT at a frequency of 15 Hz and intensity of 3, Group B received ESWT at a frequency of 10 Hz and intensity of 4, while Group C underwent the selected physical therapy program along with sham shock wave therapy as a control. Pain levels were assessed using the Visual Analog Scale (VAS) while functional improvements were evaluated using the Foot Function Index (FFI). Data was collected prior to treatment, after three sessions and at the end of six weeks (after six sessions). The three groups were well matched, and the results revealed high adherence rates (90%, 90% and 80% respectively). Results also indicated reductions in pain levels and improvements in function for both intervention groups when compared to the control group. Group A demonstrated better outcomes compared to Group B while Group C showed relatively less improvement. The study concluded a high adherence rate for the three groups as well as a small effect size detected of 0.282 that would suggest a total of 123 participants to be required to replicate the study on a larger scale. With regards to the findings of this pilot, the combination of ESWT and a targeted physical therapy program revealed a possible effective therapeutic approach for plantar fasciitis, with a higher frequency potentially yielding more favourable results.

Radial shock wave therapy (RSWT) has been recommended as an appropriate, safe and effective method in the treatment of chronic plantar fasciitis (PF). The main purpose of this study was to examine how RSWT affects gait parameters. This study included 23 patients with unilateral, chronic PF. RSWT were administered in 5 interventions, during a consecutive 3-week period. Objective kinetic (force distribution under the forefoot, midfoot, rearfoot) and spatiotemporal parameters (cadence, step length, stance phase duration) during treadmill walking at, preferred” speed were evaluated on. 4 sessions: before therapy, immediately after (primary endpoint), 3 and 6 weeks after therapy. The mean reduction in the reported pain when taking first steps in the morning from baseline to the primary endpoint, 3- and 6-weeks post procedure was 42.7%, 50.1% and 66.9% respectively. Similar reduction was seen in the reported pain during walking. After the therapy during gait at the preferred speed patients had a significantly higher force beneath the rearfoot and forefoot of both limbs. Force beneath the midfoot was not significantly affected by treatment. The step length in both limbs increased by 3.3–3.6 cm after RSWT. After the therapy stance phase duration in symptomatic foot was longer by 7% and it slightly decreased until POST-6wk. Similar changes were seen in an asymptomatic limb. The spatiotemporal and kinetic results indicate that RSWT therapy induces changes in patient’s gait structure and alter regional loading in the affected foot.

Objectives Clarity regarding accuracy and effectiveness for interventional procedures around the foot and ankle is lacking. Consequently, a board of 53 members of the Ultrasound and Interventional Subcommittees of the European Society of Musculoskeletal Radiology (ESSR) reviewed the published literature to evaluate the evidence on image-guided musculoskeletal interventional procedures around this anatomical region. Methods We report the results of a Delphi-based consensus of 53 experts from the European Society of Musculoskeletal Radiology who reviewed the published literature for evidence on image-guided interventional procedures offered around foot and ankle in order to derive their clinical indications. Experts drafted a list of statements and graded them according to the Oxford Centre for evidence-based medicine levels of evidence. Consensus was considered strong when > 95% of experts agreed with the statement or broad when > 80% but < 95% agreed. The results of the Delphi-based consensus were used to write the paper that was shared with all panel members for final approval. Results A list of 16 evidence-based statements on clinical indications for image-guided musculoskeletal interventional procedures in the foot and ankle were drafted after a literature review. The highest level of evidence was reported for four statements, all receiving 100% agreement. Conclusion According to this consensus, image-guided interventions should not be considered a first-level approach for treating Achilles tendinopathy, while ultrasonography guidance is strongly recommended to improve the efficacy of interventional procedures for plantar fasciitis and Morton’s neuroma, particularly using platelet-rich plasma and corticosteroids, respectively. Key Points • The expert panel of the ESSR listed 16 evidence-based statements on clinical indications of image-guided musculoskeletal interventional procedures in the foot and ankle. • Strong consensus was obtained for all statements. • The highest level of evidence was reached by four statements concerning the effectiveness of US-guided injections of corticosteroid for Morton’s neuroma and PRP for plantar fasciitis.

Although peloidotherapy and ESWT are effective treatments for plantar fasciitis, there is no comprehensive research that directly compares their effectiveness. Our study aimed to compare the effectiveness of ESWT and peloidotherapy on pain, quality of life and functional status in individuals diagnosed with plantar fasciitis (PF). A total of 78 patients, aged between 18 and 65 years, diagnosed with PF after a thorough anamnesis and physical examination and experiencing heel pain for at least 3 months or longer and who presented to the Clinic between January 2021 and January 2023, were included in the study. Patients were randomly allocated to two groups. The peloidotherapy group received 15 sessions of peloid therapy five days a week for three weeks, while the ESWT group received three sessions of radial-type ESWT once a week for three weeks. Additionally, all patients were given a home exercise program. All patients were evaluated three times for treatment efficacy. Pain levels were assessed using the Visual Analog Scale (VAS) and Heel Tenderness Index (HTI), functional status and quality of life were assessed using the Foot Ankle Outcome Score (FAOS) and Short Form 36 (SF-36), respectively. In both treatment groups, there was a statistically significant improvement in VAS, HTI, FAOS and SF-36 scores at the end of treatment and during the one-month follow-up, compared to the initial baseline values. A statistically significant difference in favor of peloidotherapy was observed in post-treatment symptom and pain scores ( p  = 0.046). However, this difference did not persist at the one-month follow-up. Both active treatment methods were similarly effective and no superiority was observed between them ( p  > 0.05). Peloidotherapy and ESWT treatments, along with a home exercise program, were found to be effective for patients with plantar fasciitis. In the conservative treatment of PF, both peloidotherapy and ESWT can be recommended as effective and reliable options.
