Abstract
Biomechanical dysfunction of the foot is most common cause of plantar fascia disorder and obesity and increasing age are well-known risk factors. Due to being inexpensive and quick, ultrasound imaging techniques are considered the modality of choice to assess plantar fascia. The aim of this study was to investigate the effect of age and body mass index (BMI) on sonographic findings of plantar fascia in normal population. Ultrasonography was used to measure the plantar fascia thickness of 148 healthy adults (54 males, 36.5% and 94 females, 63.5%) during a period of one year. The age, BMI, and walking distance of each participant were recorded and statistically analyzed. The mean plantar fascia thicknesses at 0.5, 1.0, and 2.0 cm distal to the insertion of the plantar fascia were 1.76 ± 0.32 mm, 2.50 ± 0.50 mm and 2.11 ± 0.41 mm respectively. The mean plantar fascia thickness for individuals ≥45 years and BMI ≥25 were significantly higher (p < .001) compared to individuals <45 years and BMI <25. In a normal population, the thickness of the plantar fascia determined by ultrasound measurement was less than 3 mm. We recommend using the position 1.0 cm distal to the calcaneal insertion of the plantar fascia as the reference point for diagnosing plantar fasciitis. The thickness of plantar fascia was significantly increased with age and BMI whereas gender, walking activity, exercise and running did not seem to affect the plantar fascia thickness.

Abstract
The plantar fascia is an important structure in the foot that acts as a major stabilizer of the longitudinal arch, along with the midfoot ligaments and intrinsic and extrinsic muscles. It is composed predominantly of longitudinally oriented collagen fibers that vary in thickness and are organized into bundles closely associated with the interstitial tissues of the foot. This composition enables the plantar fascia to withstand the weight-bearing forces concentrated on the foot while standing, jumping, walking, or running. This article discusses the normal anatomy and the various pathologies that affect the plantar fascia with an emphasis on presurgical and postoperative appearances on magnetic resonance and ultrasonography imaging.

Abstract
OBJECTIVE The aim of the study was to compare the efficacy of ultrasound-guided injection of botulinum toxin type A with corticosteroid in patients with chronic plantar fasciitis (PF). DESIGN This randomized controlled trial was conducted on 35 patients with chronic plantar fasciitis. Participants were randomly allocated into two groups: one group received methylprednisolone in to the plantar fascia ( n = 18) and the other group received botulinum toxin type A injection into the flexor digitorum brevis and quadratus plantae ( n = 17). All injections were performed under ultrasound guidance. Patients were evaluated using the Visual Analog Scale, Foot and Ankle Ability Measures, and plantar fascia thickness before the intervention, 3 wks, 12 wks, and 6 mos after the treatment. RESULTS In both groups, patients' pain and function improved significantly up to 3 wks after injection. In the botulinum toxin type A group, morning Visual Analog Scale improved significantly at 12 wks after intervention and the improvement was sustained for another 3 mos. In the botulinum toxin type A group, Foot and Ankle Ability Measures-sports subscale improved in all evaluated points, whereas in the corticosteroid group, the improvement was significant only when comparing follow-ups values to baseline. CONCLUSIONS Both ultrasound-guided botulinum toxin type A and corticosteroid injection were effective in the treatment of plantar fasciitis. Our study showed that the effects of botulinum toxin type A injection last longer than those of steroid injection.

Abstract
Background Medical imaging can be used to assist with the diagnosis of plantar heel pain. The aim of this study was to synthesise medical imaging features associated with plantar heel pain. Methods This systematic review and meta-analysis conducted searches in MEDLINE, CINAHL, SPORTDiscus, Embase and the Cochrane Library from inception to 12th February 2021. Peer-reviewed articles of cross-sectional observational studies written in English that compared medical imaging findings in adult participants with plantar heel pain to control participants without plantar heel pain were included. Study quality and risk of bias was assessed using the National Institutes of Health quality assessment tool for observational cohort and cross-sectional studies. Sensitivity analyses were conducted where appropriate to account for studies that used unblinded assessors. Results Forty-two studies (2928 participants) were identified and included in analyses. Only 21% of studies were rated ‘good’ on quality assessment. Imaging features associated with plantar heel pain included a thickened plantar fascia (on ultrasound and MRI), abnormalities of the plantar fascia (on ultrasound and MRI), abnormalities of adjacent tissue such as a thickened loaded plantar heel fat pad (on ultrasound), and a plantar calcaneal spur (on x-ray). In addition, there is some evidence from more than one study that there is increased hyperaemia within the fascia (on power Doppler ultrasound) and abnormalities of bone in the calcaneus (increased uptake on technetium-99 m bone scan and bone marrow oedema on MRI). Conclusions People with plantar heel pain are more likely to have a thickened plantar fascia, abnormal plantar fascia tissue, a thicker loaded plantar heel fat pad, and a plantar calcaneal spur. In addition, there is some evidence of hyperaemia within the plantar fascia and abnormalities of the calcaneus. Whilst these medical imaging features may aid with diagnosis, additional high-quality studies investigating medical imaging findings for some of these imaging features would be worthwhile to improve the precision of these findings and determine their clinical relevance.

Abstract
CONTEXT Plantar fasciitis (PF) is a common and devastating disease. Despite different treatments, there is no clear evidence for the effect of these treatments on PF. One of the therapy methods used in physiotherapy is dry needling (DN). So the purpose of this study is to investigate the effect of DN on the pain and range of motion of the ankle joint and plantar fascia thickness in subjects with PF who are suffering from the trigger points of the gastrocnemius and soleus muscles. METHODS In this study, 20 volunteer females with PF were randomly assigned into DN treatment and control groups. Measurements were range of motion in dorsiflexion and plantar flexion, plantar fascia thickness, and visual analog scale measured before, immediately, and 1 month after the end of the intervention in both groups. RESULTS There were significant differences in the plantar fascia thickness and visual analog scale between the 2 groups. Plantar fascia thickness (P = .016) and visual analog scale (P = .03) significantly decreased in the treatment group. However, there was no significant difference in plantar flexion (P = .582) and dorsiflexion range of motion (P = .173) between groups. CONCLUSION The result of this study showed that DN can reduce pain and plantar fascia thickness in women with PF who are suffering from trigger points of the gastrocnemius and soleus muscles. LEVEL OF EVIDENCE Level 1, randomized controlled trial.

Abstract
Purpose The aim of this study was to assess the efficacy of high-resolution ultrasonography in the assessment of plantar fascia in individuals with heel pain, before and after treatment. Material and methods This study was conducted from 2016 to 2019, during which time 44 clinically diagnosed patients of plantar fasciitis were compared to 50 normal volunteers. There were 25 males and 25 females in the control group and 42 females and two males in the study group. Thirty-eight patients had unilateral disease, and six patients had bilateral disease. The thickness of the plantar fascia was measured just anterior to its calcaneal attachment using ultrasonography. Body mass index (BMI) was also calculated in both groups. Results The plantar fascia was 2-4 mm thick in the control group whereas it was > 4 mm thick in 48 heels in the study group. With cut-off of > 4 mm as diagnostic of plantar fasciitis, this study had a sensitivity of 96%, specificity of 100%, and accuracy of 98%. BMI was increased in 60% of female patients. All patients were treated with local infiltration of corticosteroid. In 37/42 patients (43 heels) who had improved clinically, the thickness of plantar fascia was reduced to < 4 mm when assessed after six weeks of corticosteroid injection. Conclusions Diagnosis of plantar fasciitis can be easily verified by ultrasonography with plantar fascia thickness > 4 mm being suggestive of plantar fasciitis. Ultrasound can also be used to evaluate treatment response. Ultrasono-graphy helps the clinician in confirming the diagnosis of plantar fasciitis and also in assessing the response to treatment.

Abstract
OBJECTIVE Hyperglycemia leads to increase advanced glycation end products (AGEs) in patients with type 1 and type 2 diabetes. Subsequently, formation of AGEs can cause increased plantar fascial thickness (PFT), an imaging feature of plantar fasciitis (PF). This study evaluates the prevalence of PF in a contemporary cohort of type 1 diabetes and type 2 diabetes patients managed according to current standards, compared to patients without diabetes. RESEARCH DESIGN AND METHODS This is a five-year prevalence study in a large tertiary health system (approximately 535,000 patients/visits/year) with a single electronic medical record (EMR), applying a cohort discovery tool and database screen (Data Direct) with use of ICD-9 and ICD-10 codes. All patients with a PF diagnosis between 01/01/2011 and 01/01/2016 were included and divided into 3 groups: type 1 diabetes (7148 patients), type 2 diabetes (61,632 patients), and no diabetes (653,659 patients). Prevalence rates were calculated, accounting for other risk factors including BMI and gender using Fisher's exact test. RESULTS The overall prevalence of PF in the entire study population was 0.85%. Prevalence rates were higher in patients with diabetes, particularly with type 2 diabetes (42% and 64% higher compared with patients with type 1 diabetes and no diabetes respectively). Individually, PF rates were 0.92% in type 1 diabetes and 1.31% in type 2 diabetes compared with 0.80% in patients with no diabetes (Type 1 vs. no diabetes p = 0.26; Type 2 vs. no diabetes p ≪ 0.0001; Type 1 vs. Type 2 diabetes p = 0.0054). Females in all groups had higher prevalence of PF than males (p ≪ 0.0001 for all), with those patients with diabetes having higher prevalence rates than those without diabetes. Patients with higher BMI levels (BMI ≥ 30 kg/m2) were also more likely to have PF in all categories except males with type 1 diabetes (p = 0.40). CONCLUSIONS In this large contemporary population managed in a tertiary health system, prevalence rates of PF were substantially higher in patients with diabetes compared with no diabetes, particularly in type 2 diabetes. Female gender and higher BMI were also associated with higher prevalence of PF in this cohort.

Abstract
BACKGROUND: Ultrasound is a widely used diagnostic tool for patients with plantar fasciitis. However, the lack of standardization during the measurement for plantar fascia thickness has made it challenging to understand the etiology of plantar fasciitis, as well as identify risk factors, such as gender. The purpose of this study was to investigate gender differences regarding plantar fascia thickness while controlling for metatarsophalangeal (MTP) joint position in the healthy and those with unilateral plantar fasciitis. METHODS: Forty participants (20 with unilateral plantar fasciitis and 20 controls) with plantar fascia thickness (mean age, 44.8 ± 12.2 years) participated in this study. The majority were females (n = 26, 65%). Plantar fascia thickness was measured via ultrasound 3 times at 3 different MTP joint positions: (1) at rest, (2) at 30 degrees of extension, and (3) at maximal extension. RESULTS: When comparing gender differences, the males in the plantar fasciitis group had a significantly thicker plantar fascia than the females ( P = .048, η2 = 2.35). However, no significant differences were observed between healthy males and females. The males with unilateral plantar fasciitis also had significantly thicker asymptomatic plantar fasciae collectively compared with controls ( P < .05), whereas females with unilateral plantar fasciitis had a similar but not significant change. CONCLUSION: It appears that healthy males and females have similar plantar fascia thickness. However, as plantar fasciitis develops, males tend to develop thicker plantar fasciae than their female counterparts, which could have future treatment implications. LEVEL OF EVIDENCE: Level III, case-control comparative study.

Abstract
Background Ultrasound is an inexpensive method for quantifying plantar fascia thickness, especially in those with plantar fasciitis. Ultrasound has also been used to assess the effectiveness of various treatments for plantar fasciitis by comparing plantar fascia thickness before and after an intervention period. While a plantar fascia thickness over 4 mm via ultrasound has been proposed to be consistent with plantar fasciitis, some researchers believe the 4 mm plantar fascia thickness level to be a dubious guideline for diagnosing plantar fasciitis due to the lack of standardization of the measurement process for plantar fascia thickness. In particular, no universal guidelines exist on the positioning of the metatarsophalangeal (MTP) joints during the procedure and the literature also has inconsistent protocols. The purpose of this study is to investigate and compare the influence of MTP joint extension on plantar fascia thickness in healthy participants and those with unilateral plantar fasciitis. Methods The plantar fascia thickness of forty participants (20 with unilateral plantar fasciitis and 20 control) was measured via ultrasound three times at three different MTP joint positions: 1) at rest, 2) 30° of extension from the plantar surface, and 3) maximal extension possible. Results The plantar fascia became significantly thinner as MTP joint extension increased in both the plantar fasciitis group (p < 0.001) and the control group (p < 0.001). In the plantar fasciitis group, the involved plantar fascia was 1.2 to 1.3 mm thicker (p < 0.001) than the uninvolved side depending on the MTP joint position. In the control group, the difference in plantar fascia thickness between the two sides was less than 0.1 mm (p < 0.92) at any MTP joint position. Conclusions MTP joint position can influence the ultrasound measurement of plantar fascia thickness. It is recommended that plantar fascia thickness measurements be performed with the toes at rest. If MTP joints must be extended, then the toes should be extended maximally and then noted to ensure subsequent ultrasound procedures are repeated. Standardizing the position of the MTP joints is not only important for attaining the most accurate thickness measurement of the plantar fascia, but is also important to researchers who use plantar fascia thickness to determine the effectiveness of various plantar fasciitis interventions.

Abstract
Contrast-enhanced ultrasound (CEUS) is used to visualize the microvascularization in various tissues. The purpose of this study was to investigate whether CEUS could be used to visualize the microvascular volume (MV) in the plantar fascia, and to compare the method to clinical symptoms and B-mode ultrasound (US) in patients with plantar fasciitis (PF). Twenty patients with unilateral PF were included and were divided by US in insertional thickening (10), midsubstance thickening (5), and no US changes (5). The MV was measured simultaneously in both heels. Four areas in the plantar fascia and plantar fat pad were measured independently by two observers. Inter- and intra-observer correlation analyses were performed. The asymptomatic heels showed a constantly low MV, and for the whole group of patients, a significantly higher MV was found in the symptomatic plantar fascia and plantar fat pad. Inter-observer correlation as well as intra-observer agreement was excellent. The MV in the plantar fascia and plantar fat pad can be measured reliably using CEUS, suggesting that it is a reproducible method to examine patients with plantar fasciitis.

Abstract
Ultrasound (US) imaging offers significant potential in diagnosis of plantar fascia (PF) injury and monitoring treatment. In particular US imaging has been shown to be reliable in foot and ankle assessment and offers a real-time effective imaging technique that is able to reliably confirm structural changes, such as thickening, and identify changes in the internal echo structure associated with diseased or damaged tissue. Despite the advantages of US imaging, images are difficult to interpret during medical assessment. This is partly due to the size and position of the PF in relation to the adjacent tissues. It is therefore a requirement to devise a system that allows better and easier interpretation of PF ultrasound images during diagnosis. This study proposes an automatic segmentation approach which for the first time extracts ultrasound data to estimate size across three sections of the PF (rearfoot, midfoot and forefoot). This segmentation method uses artificial neural network module (ANN) in order to classify small overlapping patches as belonging or not-belonging to the region of interest (ROI) of the PF tissue. Features ranking and selection techniques were performed as a post-processing step for features extraction to reduce the dimension and number of the extracted features. The trained ANN classifies the image overlapping patches into PF and non-PF tissue, and then it is used to segment the desired PF region. The PF thickness was calculated using two different methods: distance transformation and area-length calculation algorithms. This new approach is capable of accurately segmenting the PF region, differentiating it from surrounding tissues and estimating its thickness.

Abstract
Plantar fasciitis is a very common cause of inferior heel pain that can be triggered and aggravated by prolonged standing, walking, running and obesity, among other factors. Treatments are largely noninvasive and efficacious. Supportive treatments, including the plantar fascia-specific stretch, calf stretching, appropriate orthotics and night dorsiflexion splinting, can alleviate plantar fascia pain. While local injections of corticosteroids can help with pain relief, the effects are short-lived and must be weighed against the risk of fat pad atrophy and plantar fascia rupture. Ultrasonography-guided focal extracorporeal shock wave therapy is useful for patients with chronic plantar fasciitis and referrals for this treatment can be made in recalcitrant cases. Activity modification to decrease cyclical repetitive loading of the plantar fascia should be advised during the treatment phase regardless of the chosen treatment modality.

Abstract
Plantar fascia (PF) disorders commonly cause heel pain and disability in the general population. Imaging is often required to confirm diagnosis. This review article aims to provide simple and systematic guidelines for imaging assessment of PF disease, focussing on key findings detectable on plain radiography, ultrasound and magnetic resonance imaging (MRI). Sonographic characteristics of plantar fasciitis include PF thickening, loss of fibrillar structure, perifascial collections, calcifications and hyperaemia on Doppler imaging. Thickening and signal changes in the PF as well as oedema of adjacent soft tissues and bone marrow can be assessed on MRI. Radiographic findings of plantar fasciitis include PF thickening, cortical irregularities and abnormalities in the fat pad located deep below the PF. Plantar fibromatosis appears as well-demarcated, nodular thickenings that are iso-hypoechoic on ultrasound and show low-signal intensity on MRI. PF tears present with partial or complete fibre interruption on both ultrasound and MRI. Imaging description of further PF disorders, including xanthoma, diabetic fascial disease, foreign-body reactions and plantar infections, is detailed in the main text. Ultrasound and MRI should be considered as first- and second-line modalities for assessment of PF disorders, respectively. Indirect findings of PF disease can be ruled out on plain radiography. Teaching Points • PF disorders commonly cause heel pain and disability in the general population. • Imaging is often required to confirm diagnosis or reveal concomitant injuries. • Ultrasound and MRI respectively represent the first- and second-line modalities for diagnosis. • Indirect findings of PF disease can be ruled out on plain radiography.

Abstract
BACKGROUND Musculoskeletal ultrasound is a non-invasive and low-cost modality for real-time visualisation of the plantar fascia. Ultrasound examination for plantar fasciitis is generally performed with the patient in a prone position, although the rational for using a prone position has not been validated. The aim of the study was to investigate if ultrasound examination in a supine position, which is more comfortable than the prone position, is valid. METHODS We conducted a prospective study of 30 participants with plantar fasciitis, 8 men (27 %) and 22 women (73 %), with a mean age of 53.9 ± 12.6 (range, 32 to 77) years, and an equal distribution of left and right feet. The plantar heel was divided into three portions for ultrasound examination: medial, central and lateral. Two measurements of plantar fascia thickness were obtained for each portion, with participants in 2 positions (supine and prone) and for 2 ankle postures (neutral and 15° of plantarflexion). Mean measurements of plantar fascia thickness were compared between the two positions (Wilcoxon signed rank tests for non-normally distributed data and paired t-tests for normally distributed data). Participants were asked to report their preferred position for examination, supine or prone. RESULTS The measured thickness was comparable for both supine and prone positions, for both ankle postures, neutral and 15° of plantarflexion (p > 0.05). A specific self-reported preferred position was not identified. CONCLUSIONS Ultrasound examination of plantar fasciitis can be performed in the supine position without any significant difference in measurement compared to examination in the conventional prone position. TRIAL REGISTRATION The Catholic Medical Center Office of Human Research Protection Program (CMC-OHRP)/Institutional Review Board approved the current study (Approval No. KC12DISI0338), and all participants provided their written informed consent for participation and publication.

Abstract
BACKGROUND although plantar fascia thickening is well documented as a sonographic criterion for the diagnosis of plantar fasciitis (PF), however it was less evaluated as an objective measure of response to treatment. It is unknown to what extent if any different responses to different treatments are related to the ultrasound (US) morphology changes. We aimed to evaluate changes in US findings in correlation to pain reported. METHODS this prospective observational trial included 21 plantar fasciitis patients (26 feet), resistant to conservative treatment for at least 2 months. Plantar fascia thickness and echogenicity were evaluated, compared to asymptomatic feet and correlated with visual analogue scale (VAS) and Heel Tenderness Index (HTI), before and after dexam-ethasone (DXM) iontophoresis in group I, and DXM injection in group II. RESULTS increased thickness and reduced echogenicity were constant in symptomatic feet, with high statistical significant difference compared to asymptomatic side. Correlation between plantar fascia thickness with VAS and HTI before and after treatment showed statistically significant positive correlation (p<0.05). ROC curve test showed that reduction of plantar fascia thickness by US in response to DXM had 100% sensitivity, 65.2% specificity and 69% accuracy, with higher specificity and accuracy than VAS. CONCLUSION US changes showed concurrent validity correlated with self-reported clinical improvement. Accordingly, ultrasound can be considered an objective useful tool for monitoring response to corticosteroid in patients with plantar fasciitis.

Abstract
OBJECTIVES The primary objective of this study was to determine whether the sonographic appearance of the plantar fascia is predictive of the treatment (ie, pain) response in patients receiving supportive therapy for proximal plantar fasciitis. This study was a secondary analysis of data obtained from a randomized controlled trial of ambulatory adults, which examined the efficacy of 3 different foot supports for plantar fasciitis. METHODS Participants underwent diagnostic sonographic examinations of their heel at baseline and again at 3 months by a single experienced foot and ankle surgeon. Quantitative (eg, thickness) and qualitative (eg, biconvexity) characteristics of the fascia were recorded according to a standard protocol. Logistic regression models were used to identify predictors of the pain response. RESULTS Seventy patients completed a baseline evaluation, and 63 patients completed a 3-month follow-up assessment. The pain response was not associated with the type of foot support (P> .05). The only significant indicator of an unfavorable response in the univariate and multivariate analyses was biconvexity of the plantar fascia on sonography at presentation (multivariate odds ratio, 4.76 [95% confidence interval, 1.16-19.5; P= .030). Furthermore, changes in self-reported pain over the 3-month study period were not accompanied by alterations in plantar fascia thickness over this time (r = .056; P = .671). CONCLUSIONS We conclude that patients who present with biconvexity of the plantar fascia may be less responsive to tier 1 treatment regimens that center around mechanical support of the plantar fascia. Furthermore, follow-up measurements of the fascia in this population should not weigh heavily in decisions such as return to play.

Abstract
OBJECTIVES The primary purpose of this investigation was to determine the prevalence and spectrum of asymptomatic sonographically determined structural changes in the plantar fascia and plantar heel pad among experienced runners without a history of heel pain. METHODS Thirty-nine asymptomatic runners without a history of plantar heel pain were recruited. The following sonographic measures were recorded: power Doppler sonography in the plantar heel pad and plantar fascia, echo texture of the plantar heel pad, uncompressed heel pad thickness, compressed heel pad thickness, heel pad compressibility index, plantar fascia thickness, and plantar fascia echo texture. RESULTS Doppler flow was shown in the plantar heel pads of 88% (68 of 77) of heels and 92% (36 of 39) of runners. Heel pad echo texture abnormalities were found in 86% (66 of 77) of heels and 97% (38 of 39) of runners. Mean values for right and left uncompressed heel pad thickness were 13.8 and 13.7 mm, respectively. The mean heel pad compressibility indices were 0.51 for the right heel and 0.53 for the left heel. Eight percent (6 of 77) of fat pads in 10% (4 of 39) of runners had abnormal compressibility indices. Doppler flow was present in the plantar fascia in 31% (24 of 77) of heels and 44% (17 of 39) of runners. The mean plantar fascia thicknesses were 3.78 mm for the right and 3.87 mm for the left. Forty-eight percent (37 of 77) of heels had an abnormal plantar fascia echo texture. CONCLUSIONS At least 1 potentially abnormal sonographic finding was present in each heel of all asymptomatic runners in this study. Consequently, sonographic abnormalities in the plantar heel should be interpreted within the clinical context when evaluating runners.

Abstract
Aim/Hypothesis The etiology of plantar fasciitis (PF) has been related to several risk factors, but the magnitude of the plantar load is the most commonly described factor. Although PF is the third most-common injury in runners, only two studies have investigated this factor in runners, and their results are still inconclusive regarding the injury stage. Objective Analyze and compare the plantar loads and vertical loading rate during running of runners in the acute stage of PF to those in the chronic stage of the injury in relation to healthy runners. Methods Forty-five runners with unilateral PF (30 acute and 15 chronic) and 30 healthy control runners were evaluated while running at 12 km/h for 40 meters wearing standardized running shoes and Pedar-X insoles. The contact area and time, maximum force, and force-time integral over the rearfoot, midfoot, and forefoot were recorded and the loading rate (20–80% of the first vertical peak) was calculated. Groups were compared by ANOVAs (p<0.05). Results Maximum force and force-time integral over the rearfoot and the loading rate was higher in runners with PF (acute and chronic) compared with controls (p<0.01). Runners with PF in the acute stage showed lower loading rate and maximum force over the rearfoot compared to runners in the chronic stage (p<0.01). Conclusion Runners with PF showed different dynamic patterns of plantar loads during running over the rearfoot area depending on the injury stage (acute or chronic). In the acute stage of PF, runners presented lower loading rate and forces over the rearfoot, possibly due to dynamic mechanisms related to pain protection of the calcaneal area.

Abstract
The effects of gender and various anthropometric variables were previously reported as significant predictors of plantar fascia thickness. Although a strong correlation between either the body weight or body mass index (BMI) and plantar fascia thickness were not demonstrated, a moderate relation was stated. We retrospectively investigated the role of gender, height, weight, and body mass index on plantar fascia thickness at the calcaneal origin (PFCO) and 1 cm distal from the calcaneal origin (PF1cm) and the coronal length of the plantar fascia at the calcaneal origin (CLPF) in healthy subjects. The PFCO, PF1cm, and CLPF were retrospectively measured from magnetic resonance images of 100 healthy subjects. The gender, height, weight, and body mass index of the participants were also noted. Gender was a predictive factor for the length of the CLPF. The subjects with a BMI >25 kg/m(2) had a significantly greater PFCO, PF1cm, and CLPF. Height was mildly and BMI and weight were moderately related to the PFCO. However the CLPF showed a better correlation with height, BMI, and weight than that of plantar fascia thickness. CLPF better reflected the role of weight, BMI, and height than its thickness. It is a new parameter that could be valuable in the evaluation of plantar fascia disorders.

Abstract
Objective To investigate the long-term effect of low-energy extracorporeal shock wave therapy (ESWT) for plantar fasciitis (PF) according to ultrasonography (US) findings. Methods Thirty feet of 25 patients with clinical diagnosis of PF were enrolled and divided into two groups (Apparent-US and Uncertain-US) according to US findings, such as plantar fascia thickening or hypoechogenicity. Inclusion criteria were symptom duration >6 months and a fair or poor grade in Roles-Maudsley score (RMS). ESWT (0.10 mJ/mm2, 600 shocks) was given once a week for 6 weeks. Numeric rating scale (NRS) and RMS were evaluated prior to each ESWT session, at short-term follow-up (one week after all ESWT sessions) and long-term follow-up telephone interview (mean 24 months after ESWT). Good and excellent grade in RMS were considered as treatment success. Results Repeated measure ANOVA demonstrated that NRS significantly decreased with time after ESWT up to the long-term follow-up (time effect, p<0.001) without group-time interaction (p=0.641), indicating that ESWT equally decreased pain in both groups. Overall success rate was 63.3% (short-term follow-up) and 80.0% (long-term follow-up). In comparative analysis between groups, success rate of Apparent-US and Uncertain-US at short-term follow-up was 61.9% and 66.7%, respectively, and 85.7% and 66.7%, respectively, at long-term follow-up. Conclusion If other causes of heel pain are ruled out through meticulous physical examination and ultrasonography, low-energy ESWT in PF seems to be beneficial regardless of US findings. In terms of success rate, however, long-term outcome of Apparent-US appears to be superior to Uncertain-US.

Abstract
Plantar fasciitis (PFS) is one of the most common causes of heel pain, estimated to affect 10% of the general population during their lifetime. Ultrasound (US) imaging technique is increasingly being used to assess plantar fascia (PF) thickness, monitor the effect of different interventions and guide therapeutic interventions in patients with PFS. The purpose of the present study was to systematically review previously published studies concerning the application of US in the assessment of PF in patients with PFS. A literature search was performed for the period 2000-2012 using the Science Direct, Scopus, PubMed, CINAHL, Medline, Embase and Springer databases. The key words used were: ultrasound, sonography, imaging techniques, ultrasonography, interventional ultrasonography, plantar fascia and plantar fasciitis. The literature search yielded 34 relevant studies. Sixteen studies evaluated the effect of different interventions on PF thickness in patients with PFS using US; 12 studies compared PF thickness between patients with and without PFS using US; 6 studies investigated the application of US as a guide for therapeutic intervention in patients with PFS. There were variations among studies in terms of methodology used. The results indicated that US can be considered a reliable imaging technique for assessing PF thickness, monitoring the effect of different interventions and guiding therapeutic interventions in patients with PFS.

Abstract
BACKGROUND Chronic plantar heel pain is a common and potentially debilitating condition, often caused by plantar fasciitis. Plantar calcaneal spurs were originally considered the cause of plantar fasciitis but are now regarded as an incidental finding by most authors. We aimed to test this hypothesis and to investigate predisposing factors for the development of spurs. METHODS We reviewed all lateral ankle X rays taken in our institution over a 6-month period and identified all X rays demonstrating calcaneal spurs. Then, we identified a similar number of age- and sex-matched controls without spurs. We contacted both groups by telephone and compared symptoms of heel pain, plantar fasciitis, associated comorbidities, and foot and ankle outcome scores (FAOSs). RESULTS We reviewed the X rays of 1103 consecutive patients and found a spur prevalence of 12.4%, more common in women and older patients. Questioning of the spur group and control group found a higher body mass index in the spur group. Patients with spurs were 4 times more likely to have diabetes mellitus and 10 times more likely to have lower-limb osteoarthritis. Patients with spurs had more foot pain and poorer FAOS than the control group, even when patients with plantar fasciitis were excluded. CONCLUSION Our results demonstrate that the presence of a plantar calcaneal spur may be an indicator of foot pain independent of plantar fasciitis. Although spurs may not cause foot pain themselves, they may be an indication of other associated conditions. CLINICAL RELEVANCE We have demonstrated the relevance of a radiographic finding once considered irrelevant.

Abstract
BACKGROUND Understanding the relationship between the lower leg muscles, foot structures and function is essential to explain how disease or injury may relate to changes in foot function and clinical pathology. The aim of this study was to investigate the inter-operator reliability of an ultrasound protocol to quantify features of: rear, mid and forefoot sections of the plantar fascia (PF); flexor hallucis brevis (FHB); flexor digitorum brevis (FDB); abductor hallucis (AbH); flexor digitorum longus (FDL); flexor hallucis longus (FHL); tibialis anterior (TA); and peroneus longus and brevis (PER). METHODS A sample of 6 females and 4 males (mean age 29.1 ± 7.2 years, mean BMI 25.5 ± 4.8) was recruited from a university student and staff population. Scans were obtained using a portable Venue 40 musculoskeletal ultrasound system (GE Healthcare UK) with a 5-13 MHz wideband linear array probe with a 12.7 mm × 47.1mm footprint by two operators in the same scanning session. RESULTS Intraclass Correlation Coefficients (ICC) values for muscle thickness (ICC range 0.90-0.97), plantar fascia thickness (ICC range 0.94-0.98) and cross sectional muscle measurements (ICC range 0.91-0.98) revealed excellent inter-operator reliability. The limits of agreement, relative to structure size, ranged from 9.0% to 17.5% for muscle thickness, 11.0-18.0% for plantar fascia, and 11.0-26.0% for cross sectional area measurements. CONCLUSIONS The ultrasound protocol implemented in this work has been shown to be reliable. It therefore offers the opportunity to quantify the structures concerned and better understand their contributions to foot function.

Abstract
STUDY DESIGN Single-cohort laboratory-based study. OBJECTIVES To identify whether plantar fascia vascularity and thickness are associated with foot pain and dysfunction in individuals with chronic plantar fasciitis. Background Altered plantar fascia vascularity and thickening of the fascia have been identified in individuals with chronic plantar fasciitis. METHODS Thirty-eight patients with chronic unilateral plantar fasciitis and 21 controls participated in this study. Proximal plantar fascia vascularization and thickness were assessed using ultrasound imaging, and pain and foot dysfunction were quantified with a visual analog scale and the Chinese version of the Foot Function Index, respectively. Paired t tests were used to assess the side-to-side differences in fascia thickness and vascularity index (VI) in the control and patient groups, and an unpaired t test was used to make comparisons with the patient group. Multiple regression analysis was performed to identify whether the VI and fascia thickness were associated with pain and foot dysfunction. RESULTS There were significantly higher VI (mean ± SD, 2.4% ± 1.4%) and fascia thickness (5.0 ± 1.3 mm) values in the affected feet when compared with the unaffected feet in the patient group (VI, 1.4% ± 0.5%; fascia thickness, 3.3 ± 0.7 mm) and with the dominant side of the controls (VI, 1.6% ± 0.4%; fascia thickness, 2.9 ± 0.6 mm). After accounting for age, gender, body mass index, and duration of symptoms, the VI explained 13% and 33% of the variance in pain scores measured with a visual analog scale and the pain subscale of the Foot Function Index, respectively; the VI and fascia thickness explained 42% of the variance in the Foot Function Index. CONCLUSIONS Individuals with unilateral chronic plantar fasciitis demonstrated significantly greater vascularity and thickened fascia on the affected side compared to the unaffected side and also to healthy controls. Fascia vascularity was associated independently with self-perceived pain, and both fascia vascularity and thickness were associated with foot dysfunction in patients with chronic plantar fasciitis.

Abstract
OBJECTIVE The treatment of recalcitrant plantar fasciopathy is often empirical. Imaging is usually in the form of radiographs, if undertaken at all. The aim of this study is to characterise the disease pattern in recalcitrant cases of plantar fasciopathy. This allows classification of the pathology, which in turn allows meaningful evaluation of current and future treatments. MATERIALS AND METHODS One hundred and twenty-five consecutive feet with symptoms of 'plantar fasciitis' lasting longer than 6 months (all of which had failed to improve with a stepwise conservative management protocol) had confirmed plantar fasciopathy on ultrasound scanning. The disease characteristics were evaluated based on the scan findings. RESULTS Of the patients evaluated, 66 % had typical insertional disease. The remaining 34 % had atypical distal fascia disease; 22 % had mixed insertional and distal disease, and 12 % had pure distal disease. Patients with pure distal disease were found to have either distal thickening or discrete fibromata. CONCLUSION In this cohort of recalcitrant cases, ultrasound scans detected a high proportion of atypical non-insertional plantar fascia disease. This would not be detected without imaging studies, and therefore we recommend the use of ultrasound scanning in cases of recalcitrant plantar heel pain that have failed proper first-line management, in order to confirm the clinical diagnosis and to classify the disease as either insertional or non-insertional plantar fasciopathy (or mixed disease). Only in this way can treatments for this group of patients be systematically evaluated against different disease patterns to determine their effectiveness.

Abstract
PURPOSE To evaluate the use of axial-strain real-time sonoelastography in patients with plantar fasciitis compared with that in healthy control subjects. MATERIALS AND METHODS Institutional review board approval and patients' consent were obtained. Eighty feet of 80 patients (43 men, 37 women; mean age ± standard deviation, 46.3 years ± 8.7) with plantar fasciitis and 50 feet of 50 asymptomatic volunteers (27 men, 23 women; mean age, 44.3 years ± 8.0) were prospectively evaluated. Individuals graded heel pain with a visual analogue scale and underwent B-mode ultrasonography (US) and real-time sonoelastography. Maximum fascial thickness was measured, and two longitudinal images were recorded with both modalities. Two radiologists who were blinded to clinical symptoms independently reviewed images for hypoechoic echotexture and fascial-border blurring at B-mode US and semiquantitative elasticity score at real-time sonoelastography (blue, 1; green, 2; red, 3), with the fascia divided into proximal, intermediate, and distal sections. RESULTS No differences were found for sex (P = .999) or age distribution (P = .144) between groups. Fascial thickening, hypoechoic echotexture, and fascial-border blurring at B-mode US were increased in patients versus control subjects (P < .001), and fascial thickening and hypoechoic echotexture correlated with heel pain score (r > .475, P < .001). Plantar fasciae of patients (median score, 11; interquartile interval, 10-12) were less elastic than those of control subjects (median score, 7; interquartile interval, 6-7.25) (P < .001). Image interpretation yielded high interobserver reproducibility (κ ≥ .80). Pain and real-time sonoelastographic scores correlated significantly (r = 0.851, P < .001). Pain was associated with older age (t = 3.7, P < .001), fascial thickening (t = 7.3 [multiple stepwise regression model], P < .001), and total real-time sonoelastographic score (t = 10.2, P < .001) but not with sex, fascial-border blurring, or hypoechoic echotexture. Accuracy increased from 90.0% with B-mode US to 95.4% with real-time sonoelastography (P = .016). CONCLUSION Real-time sonoelastography can show plantar fasciitis, increase diagnostic performance of B-mode US, and assist in cases of inconclusive B-mode US findings.

Abstract
BACKGROUND The purpose of this study was to determine whether changes in plantar fascia thickness are a reliable gauge of efficacy of treatment protocols for plantar fasciitis. METHODS Thirty-nine feet (30 patients) with plantar fasciitis received an ultrasound examination to measure the thickness of the medial band of the plantar fascia. Each patient assessed his or her pain using the visual analogue scale. Following various treatments, a second ultrasound examination was performed and the thickness of the plantar fascia was again measured and subjective pain level assessed. RESULTS Twenty-nine feet (74.4%) showed a decrease in plantar fascia thickness and a decrease in pain. One foot (2.6%) experienced an increase in fascia thickness and reported an increase in pain. Four feet (10.3%) had an increase in thickness of the plantar fascia and reported no change in pain level. Three feet had minor increases in fascia thickness but reported a decrease in pain (7.7%). One foot (2.6%) had no change in fascia thickness but a decrease in pain and one foot (2.6%) had a decrease in the plantar fascia but no change in pain level. The average reduction in fascia thickness was 0.82 mm ± 1.04 mm, correlating with an average improvement in pain of 3.64 ± 2.7 (P < 0.005). CONCLUSIONS This study provides evidence that changing thickness of the plantar fascia is a valid objective measurement to assess effectiveness of new or existing treatment protocols.

Abstract
BACKGROUND To evaluate the intra- and interrater reliability of ultrasonographic measurements of the thickness and echogenicity of the plantar fascia. METHODS Eleven patients (20 feet), who complained of inferior heel pain, and 26 volunteers (52 feet) were enrolled. Two sonographers independently imaged the plantar fascia in both longitudinal and transverse planes. Volunteers were assessed twice to evaluate intrarater reliability. Quantitative evaluation of the echogenicity of the plantar fascia was performed by measuring the mean gray level of the region of interest using Digital Imaging and Communications in Medicine viewer software. RESULTS Sonographic evaluation of the thickness of the plantar fascia showed high reliability. Sonographic evaluations of the presence or absence of hypoechoic change in the plantar fascia showed surprisingly low agreement. The reliability of gray-scale evaluations appears to be much better than subjective judgments in the evaluation of echogenicity. Transverse scanning did not show any advantage in sonographic evaluation of the plantar fascia. CONCLUSIONS The reliability of sonographic examination of the thickness of the plantar fascia is high. Mean gray-level analysis of quantitative sonography can be used for the evaluation of echogenicity, which could reduce discrepancies in the interpretation of echogenicity by different sonographers. Longitudinal instead of transverse scanning is recommended for imaging the plantar fascia.

Abstract
The plantar fascia is a multilayered band of fibrous tissue that support and maintain the longitudinal arch of the foot. We report a 34-old obese woman with heel pain for the past 3 years. On physical examination, she presented painful plantar fascia throughout extension of the foot. In addition, a soft painful, mobile nodule was also palpated in the medial aspect of her left heel. An US examination of her left foot showed an increased thickness of her plantar fascia with reduced echogenity, the presence of an effusion and a positive power Doppler signal. Positive US Doppler signal may be helpful in evaluating patients with plantar fasciitis and is suggestive of the presence of active microcirculation.

Abstract
Ultrasound, well recognized as an effective diagnostic tool, reveals a thickening of the plantar fascia in patients with plantar fasciitis/fasciosis disease. The authors hypothesized that ultrasound would also reveal a decrease in the plantar fascia thickness for patients undergoing treatment for the disease, a hypothesis that, heretofore, had been only tested on a limited number of subjects. They conducted a more statistically significant study that found that clinical treatment with injection and biomechanical correction does indeed diminish plantar fascia thickness as shown on ultrasound. The study also revealed that patients experience the most heightened plantar fascia tenderness toward the end of the day, and improvement in their symptomatic complaints were associated with a reduction in plantar fascia thickness. As a result, the authors conclude that office-based ultrasound can help diagnose and confirm plantar fasciitis/fasciosis through the measurement of the plantar fascia thickness. Because of the advantages of ultrasound--that it is non-invasive with greater patient acceptance, cost effective and radiation-free--the imaging tool should be considered and implemented early in the diagnosis and treatment of plantar fasciitis/fasciosis.

Abstract
PURPOSE To determine intra- and interobserver reliability and measurement precision of sonographic assessment of plantar fascia thickness when using one, the mean of two, or the mean of three measurements. METHODS Two experienced observers scanned 20 healthy subjects twice with 60 minutes between test and retest. A GE LOGIQe ultrasound scanner was used in the study. The built-in software in the scanner was used to measure the thickness of the plantar fascia (PF). Reliability was calculated using intraclass correlation coefficient (ICC) and limits of agreement (LOA). RESULTS Intraobserver reliability (ICC) using one measurement was 0.50 for one observer and 0.52 for the other, and using the mean of three measurements intraobserver reliability increased up to 0.77 and 0.67, respectively. Interobserver reliability (ICC) when using one measurement was 0.62 and increased to 0.82 when using the average of three measurements. LOA showed that when using the average of three measurements, LOA decreased to 0.6 mm, corresponding to 17.5% of the mean thickness of the PF. CONCLUSIONS The results showed that reliability increases when using the mean of three measurements compared with one. Limits of agreement based on intratester reliability shows that changes in thickness that are larger than 0.6 mm can be considered actual changes in thickness and not a result of measurement error.

Abstract
Background Chronic plantar heel pain (CPHP) is a generalised term used to describe a range of undifferentiated conditions affecting the plantar heel. Plantar fasciitis is reported as the most common cause and the terms are frequently used interchangeably in the literature. Diagnostic imaging has been used by many researchers and practitioners to investigate the involvement of specific anatomical structures in CPHP. These observations help to explain the underlying pathology of the disorder, and are of benefit in forming an accurate diagnosis and targeted treatment plan. The purpose of this systematic review was to investigate the diagnostic imaging features associated with CPHP, and evaluate study findings by meta-analysis where appropriate. Methods Bibliographic databases including Medline, Embase, CINAHL, SportDiscus and The Cochrane Library were searched electronically on March 25, 2009. Eligible articles were required to report imaging findings in participants with CPHP unrelated to inflammatory arthritis, and to compare these findings with a control group. Methodological quality was evaluated by use of the Quality Index as described by Downs and Black. Meta-analysis of study data was conducted where appropriate. Results Plantar fascia thickness as measured by ultrasonography was the most widely reported imaging feature. Meta-analysis revealed that the plantar fascia of CPHP participants was 2.16 mm thicker than control participants (95% CI = 1.60 to 2.71 mm, P < 0.001) and that CPHP participants were more likely to have plantar fascia thickness values greater than 4.0 mm (OR = 105.11, 95% CI = 3.09 to 3577.28, P = 0.01). CPHP participants were also more likely to show radiographic evidence of subcalcaneal spur than control participants (OR = 8.52, 95% CI = 4.08 to 17.77, P < 0.001). Conclusion This systematic review has identified 23 studies investigating the diagnostic imaging appearance of the plantar fascia and inferior calcaneum in people with CPHP. Analysis of these studies found that people with CPHP are likely to have a thickened plantar fascia with associated fluid collection, and that thickness values >4.0 mm are diagnostic of plantar fasciitis. Additionally, subcalcaneal spur formation is strongly associated with pain beneath the heel.

Abstract
Introduction: The objective of the study is to compare the efficacy of flat insoles, bone spur pads, pre-fabricated orthotics and customised orthotics in reducing plantar contact pressure of subjects with plantar fasciitis.
Materials and Methods: This is a controlled non-blinded com- parative study conducted in a tertiary medical institute. Thirty subjects with unilateral plantar fasciitis between the ages of 20 and 65 years were recruited at the sports medicine clinic. The contact pressures and pressure distribution patterns in both feet for each subject were measured with sensor pressure mats while standing. Repeat measurements were made with the subjects wearing shoes, flat insoles, bone spur heel pads, pre-fabricated insoles and customised orthotics on both feet. The asymptomatic side was used as the control. Contact pressure measurements of the symptomatic and asymptomatic feet and power ratio of the pressure distribution pattern of the rearfoot were then compared.
Results: Contact pressure was higher on the asymptomatic side due to unequal distribution of weight. Bone spur heel pads were ineffective in reducing rearfoot pressure while formthotics and customised orthotics reduced peak rearfoot pressures significantly. The power ratio of the rearfoot region decreased with the use of formthotics and customised orthotics.
Conclusion: Pre-fabricated orthotics and customised orthotics reduced rearfoot peak forces on both sides while bone spurs heel pad increase rearfoot peak pressures. Pre-fabricated and customised orthotics are useful in distributing pressure uniformly over the rearfoot region.

Abstract
Plantar fasciitis is a common problem without known etiology. It responds well to multiple conservative modalities and no particular modality has been demonstrated to be clearly superior in the treatment of this condition. Over 90% of patients will be cured by non-operative treatment but this may require 6 to 12 months of treatment and encouragement by the physician. Extracorporeal shock wave therapy is a noninvasive treatment with a success rate comparable to surgery and a low complication rate. Surgery can be done endoscopically or open with similar long-term outcomes. Patients appear to recover from endoscopic treatment 4 to 5 weeks earlier than the open group. If there is a suggestion of FBLPN entrapment, then patients should have an open release.

Abstract
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.

Abstract
Plantar fasciitis is the most common cause of plantar heel pain. Its characteristic features are pain and tenderness, predominately on the medial aspect of the calcaneus near the sole of the heel. Considering a complete differential diagnosis of plantar heel pain is important; a comprehensive history and physical examination guide accurate diagnosis. Many nonsurgical treatment modalities have been used in managing the disorder, including rest, massage, nonsteroidal anti-inflammatory drugs, night splints, heel cups/pads, custom and off-the-shelf orthoses, injections, casts, and physical therapy measures such as shock wave therapy. Most reported treatment outcomes rely on anecdotal experience or combinations of multiple modalities. Nevertheless, nonsurgical management of plantar fasciitis is successful in approximately 90% of patients. Surgical treatment is considered in only a small subset of patients with persistent, severe symptoms refractory to nonsurgical intervention for at least 6 to 12 months.

Abstract
The heels of 23 patients who were diagnosed with unilateral/bilateral plantar fasciitis were evaluated via ultrasonography and compared with their asymptomatic feet and a control group of 23 people. Plantar fascial thickness, echogenity, and heel pad thickness were evaluated, and the results were statistically analyzed. For symptomatic feet, increased thickness of the fascia and reduced echogenity were constant ultrasonographic findings (mean, 4.79 mm for symptomatic feet; 2.17 mm for control group, P < .05). No significant difference was found between heel pads of the diseased and healthy feet (mean, 12.96 mm for symptomatic feet; 13.10 mm for control group; P > .05). Ultrasonography seems to be a valuable, noninvasive diagnostic tool for the evaluation of plantar fasciitis.

Abstract
PURPOSE The study was aimed to investigate plantar fascia thickness at different locations in healthy asymptomatic subjects and its relationship to the following variables: weight, height, sex and age. MATERIAL AND METHODS The study evaluates 96 feet of healthy asymptomatic volunteers. The plantar fascia thickness was measured at four different locations: 1cm proximal to the insertion of the plantar fascia, at the insertion of the plantar fascia on the calcaneus and separate out 1 cm + 2 cm distal to the insertion. A 10 MHz linear-array transducer was used. RESULTS There were statistically significant differences in plantar fascia thickness at the four different locations (p<0.001) although no differences in PF thickness were found between the two distal from insertion locations (1 and 2 cm). Multiple regression analysis showed sex as independent predictor of plantar fascia thickness at 1cm proximal to the insertion. At origin and 1cm distal to insertion weight was an independent predictor of plantar fascia thickness. CONCLUSIONS There are differences of thickness at different locations of plantar fascia measured by ultrasonography. Thickness at 1cm proximal to the insertion is influenced by sex and thickness at origin and at 1cm distal to the insertion has a direct relationship with body weight. This could be attributed to the overloading effect that weight has on plantar fascia in healthy symptomatic subjects at these two locations. Height and age did not seem to influence as independent variables in plantar fascia thickness among non-painful subjects.
