Plantar Fascia Thickness and Stiffness in Healthy Individuals vs Patients With Plantar Fasciitis.

Plantar fasciitis is a major cause of heel pain, resulting from repetitive trauma to the plantar fascia and leading to structural changes within the fascia. It has been observed that plantar fascia thickness in plantar fasciitis patients exceeds that of normal individuals. However, the biomechanical properties of the plantar fascia in patients with plantar fasciitis remain unclear. Therefore, this study aimed to compare plantar fascia stiffness between healthy individuals and patients with plantar fasciitis across different areas. Fifty-eight participants were divided into 2 groups: 29 healthy individuals and 29 individuals with plantar fasciitis. B-mode ultrasonography was used to assess plantar fascia thickness, whereas shear wave elastography was employed to measure plantar fascia stiffness. The study focused on 3 distinct areas: calcaneal insertion, 1-cm distal area, and 2-cm distal area. Additionally, the most painful area reported by patients was marked in the plantar fasciitis group. The findings showed that the plantar fasciitis group exhibited significantly greater plantar fascia stiffness in almost all areas compared to the healthy group (P < .05). Moreover, the stiffness of the plantar fascia in the most painful area demonstrated the highest value compared with other areas within the plantar fasciitis group (P < .05). This study suggests structural and mechanical changes in the plantar fascia in patients with plantar fasciitis.

Effectiveness of neurokinetic therapy on pain and plantar fascia thickness among patients with plantar fasciitis

Objectives: Identify the effectiveness of neurokinetic therapy on pain and plantar fascia thickness in patients with plantar fasciitis. Method: An experimental study was performed on 80 patients with plantar fasciitis after screening based on selection criteria. The patients were randomly allocated into two groups: the neurokinetic therapy group (n = 40) and the foot core exercises group (n = 40). In both groups, the treatments were given for two weeks, five days each week. The pre-and post-test results were assessed. A statistical analysis was performed on the gathered data. Result: A significant statistical difference was observed between the groups; the post-test mean value of the Foot Function Index scale in the neurokinetic therapy group was 129.12, while in the foot core exercises group was 141.42. Additionally, the post-test mean value of the therapeutic ultrasound in the neurokinetic therapy group was 3, whereas in the foot core exercises group was 3.38. These values yielded a p-value of less than 0.001. Conclusion: This study demonstrated an improvement in both groups. However, the neurokinetic therapy group showed a significant improvement in pain, functionality, and plantar fascia thickness compared to the foot core exercises group. Level of evidence IV; Experimental study.

Treating Plantar Fasciitis: Platelet-Rich Plasma or Corticosteroids? A Single-Center Clinical Trial

Background: Plantar fasciitis (PF) is one of the leading causes of heel discomfort worldwide. There is no definitive treatment available for PF; however, two primary therapies are under investigation: Local injection of either corticosteroids or platelet-rich plasma (PRP). There are disagreements regarding the precise and effective dosage of these therapeutic approaches and their superiority over each other. Objectives: This study was conducted to compare the effects of corticosteroids and PRP in the treatment of PF. Methods: In this single-center clinical trial, 30 patients were divided into two groups (PRP vs. corticosteroids), with 15 patients in each group. In addition to receiving medication treatment, participants were given daily exercise regimens. The PRP group had a mean age of 44.07 ± 8.21 years, while the corticosteroid group had a mean age of 44 ± 9.85 years. The efficacy of these interventions was assessed primarily using the Numeric Pain Rating Scale (NPRS), the Roles and Maudsley score (RM), and the Foot and Ankle Disability Index (FADI). Results: Over a 3-month period, the NPRS decreased in the corticosteroid group from 7.07 ± 0.95 to 3.69 ± 1.43, and in the PRP group from 7.76 ± 0.92 to 3 ± 1.68 (P &lt; 0.001). The FADI improved in the corticosteroid group from 54.84 ± 8.33 to 75.76 ± 11.96, and in the PRP group from 49.3 ± 10.11 to 78.15 ± 16.76 (P &lt; 0.001). Plantar fascia thickness decreased in the corticosteroid group from 5.03 ± 0.62 to 4.51 ± 0.59, and in the PRP group from 5.43 ± 0.91 to 4.38 ± 1.04 (P &lt; 0.001). The results indicated that both groups demonstrated significant improvement in the first three months. Although the PRP group showed greater improvement than the corticosteroid group after three months, the differences between the two groups were not statistically significant. Conclusions: Our results showed that the effects of corticosteroid injections subside after one month, whereas PRP has more stable effects over time.

The Role of Bone Edema in Plantar Fasciitis Treated with Temperature-Controlled High-Energy Adjustable Multi-Mode Emission Laser (THEAL) and Exercise: A Prospective Randomized Clinical Trial.

Plantar fasciitis is one of the most common causes of foot pain; in 35% of cases, it is also associated with bone edema of the heel. The aim of this study was to investigate the relationship between bone edema and the outcomes of temperature-controlled high-energy adjustable multi-mode emission laser (THEAL) and/or exercises in patients with plantar fasciitis. A prospective randomized clinical trial was designed, in which 48 patients suffering from plantar fasciitis, with or without bone edema, were treated with temperature-controlled high-energy adjustable multi-mode emission laser and exercises (the laser group) or with exercises only (the control group). The patients were evaluated at recruitment (T0) and at 2 (T1) and 6 months (T2), monitoring pain (with the Visual Analogue Scale), functionality (with the Foot Function Index), perception of improvement (with the Roles and Maudsley Score), and fascia thickness (with ultrasound examination). In both groups, there was a significant improvement in pain, functional recovery, perception of remission, and a reduction in plantar fascia thickness at T1 and T2. The laser group presented statistically better values at T2 for the Roles and Maudsley Score (z: 2.21; 0.027). The regression analysis showed that a greater reduction in fascia thickness occurred in the laser group (p-value: 0.047). In conclusion, the two conservative treatments were effective in patients suffering from plantar fasciitis, even in the presence of bone edema, but with lesser results.

EVALUATION OF PLANTAR FASCIA THICKNESS ACCORDING TO THE MORPHOMETRIC OF THE FOOT

OBJECTIVE: In our study, it was aimed to examine the relationship among plantar fascia thickness, foot morphometric values, and Achilles tendon thickness. MATERIAL AND METHODS: The study was carried out on young volunteers who did not engage in any active regular sports. In total, morphometric measurements were performed on 64 feet (17 men, 15 women). The thickness of the plantar fascia on the ultrasound image was measured. Foot length, foot width, heel width, and ankle circumference were used as foot morphometric variables. RESULTS: It was determined that the plantar fascia thickness was greater than 4 mm in 14.7% of young healthy male individuals. The plantar fascia thickness was found to be less than 3.6 mm in all young female individuals. In men, plantar fascia thickness was found to be moderately positively correlated with foot length and ankle circumference (p&amp;lt;0.05). However, it was interesting that there was no correlation between plantar fascia thickness and foot width. When all the participants were evaluated together, a moderate positive correlation was found between plantar fascia thickness and foot length, ankle circumference, and Achilles tendon thickness, while a weak correlation was found with foot width and heel diameter (p&amp;lt;0.001). CONCLUSIONS: The addition of foot morphometry and plantar fascia data to the literature, depending on different racial and geographical conditions, allows anatomists and anthropologists to make necessary comparisons. To support the diagnosis of plantar fasciitis, the accepted “plantar fascia thickness greater than 4 mm” should be reviewed and discussed separately for both men and women.

Effect of extracorporeal shockwave therapy on plantar fascia thickness in plantar fasciitis: a systematic review and meta-analysis of randomized controlled trials.

Extracorporeal shockwave therapy (ESWT) has been used as a therapeutic option for plantar fasciitis. The objective was to investigate the effect of ESWT over the plantar fascia thickness. MEDLINE, Embase, Web of Science, and SCOPUS databases were searched for randomized controlled trials evaluating the effect of ESWT in patients with plantar fasciitis, comparing ESWT with another treatment. Meta-analysis was conducted using a random-effects model and the generic inverse variance method. Meta-regression and subgroup analyses were also carried out. A total of 14 studies (867 participants) were included. ESWT significantly decreased plantar fascia thickness (weighted mean difference [WMD], -0.21mm [95% CI -0.39, -0.02]; p = 0.03). No significant improvement in pain was observed (WMD, -0.51cm [95% CI -1.04, 0.01]; p = 0.06) compared with non-surgical interventions. Our results suggest that plantar fascia thickness is significantly decreased after ESWT intervention in patients with plantar fasciitis. However, pain relief was not significantly improved compared to other non-surgical interventions.

The Importance of Preconditioning for the Sonographic Assessment of Plantar Fascia Thickness and Shear Wave Velocity.

Plantar fasciopathy is a very common musculoskeletal complaint that leads to reduced physical activity and undermines the quality of life of patients. It is associated with changes in plantar fascia structure and biomechanics which are most often observed between the tissue's middle portion and the calcaneal insertion. Sonographic measurements of thickness and shear wave (SW) elastography are useful tools for detecting such changes and guide clinical decision making. However, their accuracy can be compromised by variability in the tissue's loading history. This study investigates the effect of loading history on plantar fascia measurements to conclude whether mitigation measures are needed for more accurate diagnosis. The plantar fasciae of 29 healthy participants were imaged at baseline and after different clinically relevant loading scenarios. The average (±standard deviation) SW velocity was 6.5 m/s (±1.5 m/s) and it significantly increased with loading. Indicatively, five minutes walking increased SW velocity by 14% (95% CI: -1.192, -0.298, t(27), p = 0.005). Thickness between the calcaneal insertion and the middle of the plantar fascia did not change with the tissues' loading history. These findings suggest that preconditioning protocols are crucial for accurate SW elastography assessments of plantar fasciae and have wider implications for the diagnosis and management of plantar fasciopathy.

A Novel Combination Strategy of Ultrasound-Guided Percutaneous Radiofrequency Ablation and Corticosteroid Injection for Treating Recalcitrant Plantar Fasciitis: A Retrospective Comparison Study.

The best treatment yielding clinical benefits was still equivocal and controversial for the treatment of recalcitrant plantar fasciitis (PF). This study aimed to propose a novel combination strategy of ultrasound-guided percutaneous radiofrequency ablation (RFA) and corticosteroid injection (CI) for recalcitrant PF, and to compare its therapeutic effects with CI alone and continued conservative management. We retrospectively reviewed consecutive patients with recalcitrant PF who underwent combined strategy (RFA + CI), CI alone, and continue conservative treatment at our institution between October 2021 and February 2023. The technical pearls were described elaborately. A comparison of demographic data and clinical outcomes, including visual analog scale (VAS), Ankle-Hindfoot Scale (AOFAS-AHS), and plantar fascia thickness, were conducted among the three groups. Seventy-one eligible patients were enrolled in this study, with 17 in the combined strategy group, 25 in the CI group, and 29 in the continued conservative treatment group. Both the combined strategy group and the CI group showed significant improvements in VAS scores, AOFAS-AHS scores, and significant reductions in plantar fascia thickness during the 12-month follow-up period compared to those preoperatively (P < 0.05). The combined strategy group achieved comparable immediate pain relief to the CI group after the intervention ([25.7 ± 15.7] vs. [20.6 ± 17.6], P = 0.850). However, the combined strategy group demonstrated superior improvement in symptom and function compared to the CI group at the 3-month (VAS: [21.9 ± 13.5] vs. [39.6 ± 20.4]; AOFAS-AHS: [77.9 ± 12.4] vs. [60.5 ± 17.4], P < 0.05) and 12-month follow-up (VAS: [15.7 ± 12.0] vs. [56.8 ± 17.5]; AOFAS-AHS: [84.5 ± 10.7] vs. [53.8 ± 12.4], P < 0.05). Obvious adverse effects or complications were not identified in either group, while two cases (11.8%) in the combined strategy group and five cases (20.0%) in the CI group experienced unsatisfactory symptom remission. We introduced and detailed a novel combination strategy involving ultrasound-guided percutaneous RFA and CI for treating recalcitrant PF. The strategy is both effective and safe in alleviating pain and enhancing function throughout the entire treatment course.

Effects of technological running shoes versus barefoot running on the intrinsic foot muscles, ankle mobility, and dynamic control: a novel cross-sectional research

BackgroundTechnological running shoes have become increasingly popular, leading to improvements in performance. However, their long-term effects on foot musculature and joint mobility have not been thoroughly studied. ObjectiveTo compare the activation of the intrinsic foot muscles between runners wearing technological footwear and barefoot runners. Secondary objectives included assessing ankle dorsiflexion (DF) range of motion (ROM) and dynamic postural control in both groups. MethodsA cross-sectional study was conducted involving 22 technological footwear runners and 22 barefoot runners. Ultrasonography was used to measure the thickness of the plantar fascia (PF) and the quadratus plantae (QP), abductor digiti minimus (ADM), abductor hallucis (AH), and flexor hallucis longus (FHL) muscles. Ankle mobility and dynamic postural control were also recorded. ResultsUltrasonography measurements showed statistically significant differences for PF thickness (mean difference [MD]: -0.10 cm; 95% CI: -0.13, -0.05 cm), QP cross-sectional area (CSA) (MD: -0.45 cm2; 95% CI: -0.77, -0.12 cm2), ADM CSA (MD: -0.49 cm2; 95% CI: -0.70, -0.17 cm2), and FHL thickness (MD: 0.82 cm; 95% CI: 0.53, 1.09 cm), with all measurements being lower in the group wearing technological footwear compared to the barefoot runners. Ankle DF ROM was also significantly greater for the barefoot runners (MD: -5.1°; 95% CI: -8.6, -1.7°). ConclusionsThese findings suggest potential implications for the foot musculature and ankle mobility in runners using technological footwear.

Efficacy of extracorporeal shockwave therapy, compared to corticosteroid injections, on pain, plantar fascia thickness and foot function in patients with plantar fasciitis: A systematic review and meta-analysis

Objective To compare the efficacy of extracorporeal shock waves versus corticosteroids injections on pain, thickness of plantar fascia and foot function in patients with plantar fasciitis. Secondarily, to assess the efficacy of radial and focused extracorporeal shock waves and the most appropriated intensity (high, medium or low). Data sources PubMed, SCOPUS, CINAHL and PEDro, until April 2024, according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Review methods Randomized controlled trials comparing the efficacy of extracorporeal shock waves versus corticosteroids injections on pain intensity and sensitivity, thickness of plantar fascia and foot function in patients with plantar fasciitis. Methodological quality and risk of bias were assessed using PEDro Scale and Cochrane Risk of Bias Tool. Pooled effect was calculated using the standardized mean difference (SMD) and its 95% confidence interval (95%CI). Results Sixteen studies involving 1121 patients, showing a mean of 6 points in PEDro scale, were included. At three months, extracorporeal shock waves were better than corticosteroids injections in reducing pain (SMD −0.6; 95%CI −1.1 to −0.11) and thickness of the plantar fascia (SMD −0.4; 95%CI −0.8 to −0.01) and increasing foot function (SMD 0.27; 95%CI 0.12–0.44). At six months, extracorporeal shock waves are more effective in reducing pain (SMD −0.81; 95%CI −1.6 to −0.06) and increasing foot function (SMD 0.67; 95%CI 0.45–0.89). Local pain and slight erythema were the most frequent adverse events. Conclusions Extracorporeal shock waves are a safe therapy, presenting more efficacy than corticosteroids injections in improving pain, thickness of plantar fascia and foot function at mid-term.

PROSPECTIVE STUDY ON THE EFFECTIVENESS OF PLATELET-RICH PLASMA IN MANAGING CHRONIC PLANTAR FASCIITIS

Objectives: The objectives of this study were as follows: (1) Assess the impact of a single dose of platelet-rich plasma (PRP) injection on visual analog scale (VAS) scores for heel pain. (2) Evaluate the functional outcome scores following PRP treatment for chronic plantar fasciitis. (3) Measure and confirm the restoration of plantar fascia thickness through ultrasound (USG) assessments. (4) Determine the safety and viability of local PRP injection as a treatment option for individuals with chronic plantar fasciitis. Methods: This hospital-based prospective case series, spanning January 2019 to January 2020, enrolled 40 participants aged 25–65 with unilateral, persistent plantar fasciitis resistant to conservative treatment. Exclusion criteria included BMI ≥30, various pathologies, and recent injections. Ethical clearance was obtained, and participants received autologous PRP injections, with ultrasound measuring plantar fascia thickness. Post-injection, patients were monitored for adverse reactions, initiated stretching exercises, and progressed to weight-bearing activities after 6 weeks. Results: The study cohort, averaging 45 years (standard deviation [SD] 7.7), primarily comprised females with the right-foot prevalence. Symptom duration averaged 20 weeks (SD 4.5). Pre-injection VAS scores (6.7±1.2) significantly improved at 6 weeks (2.9±0.6) and 12 weeks (2.0±0.9) post-PRP injection (p&lt;0.001). Plantar fascia thickness reduced from 5.1 mm (SD 0.6) to 4.1 mm (SD 0.5) at 12 weeks (p&lt;0.001) and regular foot thickness: 3.7 mm (SD 0.5). Conclusion: The study reveals that a singular PRP injection brings about substantial and clinically meaningful enhancements in heel pain, functional outcomes, and the restoration of plantar fascia thickness, supported by ultrasound measurements. This underscores local PRP injection as a viable and safe therapeutic choice for those grappling with chronic plantar fasciitis.

Utility of Shear Wave Elastography for the Diagnosis of Plantar Fasciitis: Comparison Between Symptomatic and Asymptomatic Sides in Unilaterally Affected Patients.

Plantar fasciitis (PF) can cause pain in the heel, which can affect everyday activities. While it often resolves on its own, diagnosing PF to rule out other hind foot conditions by imaging modality in cases of recurrence can be difficult. Methods such as MRI and ultrasonography are helpful, but the use of elastography, specifically shear wave elastography (SWE), as a tool for diagnosing PF is being studied. This comparative observational studyincluded patients over 18 years presenting with unilateral hind foot pain who were investigated using SWE. Exclusions comprised those who were bilaterally affected and with foot deformities, trauma history, or prior injection therapy. Patients' AOFAS Ankle-Hindfoot Scores were assessed along with visual analog scale (VAS) scores, followed by SWE examination of both heels. The study found no significant difference in the plantar fascia thickness between affected and unaffected sides, with a mean thicknessof 4.3±0.8mm and 5.1±0.6mm, respectively. Shear wave velocity (SWV) was lower on the affected side, indicating reduced stiffness compared to the unaffected side. The Spearman rank test revealed strong direct correlations between SWV and both the VASand HF-AOFAS scores on the affected side. The study observed that SWEenhances B-mode ultrasonography in detecting early PFeven with normal plantar fascia thickness, offering a user-independent and reliable tool for treatment monitoring and correlation with functional and pain scores. Further research with larger populations can aid in developing a clinico-radiological classification system for PF, improving prognostication and treatment guidance.

Functional Morphologic Changes of the Heel Fat Pad and Plantar Fascia in Patients With Heel Pain During Weightbearing and Nonweightbearing.

This study aimed to investigate the thickness changes of the heel fat pad and the plantar fascia associated with loading and unloading in healthy individuals and patients with heel pain and reveal the differences between them. The study included adult male participants with (n = 9) and without (n = 26) heel pain. The participants placed their right foot on an evaluation apparatus with a polymethylpentene resin board (PMP), while their left foot was positioned on a weighing scale used to adjust the loading weight. The heel fat pad was differentiated into superficial Microchamber and deep Macrochamber layers. These layers and plantar fascia thickness were measured using an ultrasonographic imaging device at loading phase ranging from 0% to 100% of their body weight and unloading phase from 100% to 0%. Additionally, the study examined the thickness change ratios of the superficial and deep heel fat pad layers when the load increased from 0% (unload) to 100% (full load). In healthy individuals and patients with heel pain, no significant thickness changes were observed in the Microchamber layer of the heel fat pad or the plantar fascia during loading and unloading evaluations. However, significant thickness changes were observed in the Macrochamber layer of the heel fat pad, and the pattern of change differed between the loading and unloading phases. Additionally, patients with heel pain showed differences in the thickness change and thickness change ratios of the microchamber and macrochamber layers of the heel fat pad during both loading and unloading phases. The thickness of the plantar fascia did not show significant differences between both groups. Compared with healthy individuals, in our relatively small study, patients with heel pain had greater deep fat pad compression in loading and less recovery after load removal. This finding suggests that these patients have different intrinsic fat pad function and related morphology than those without heel pain. Level III, retrospective cohort study.

Ultrasound-guided injection of corticosteroid versus placebo in management of plantar fasciitis

: Plantar Fasciitis (PF) is a prevalent musculoskeletal condition causing heel pain, with approximately 1 million annual U.S. physician visits. It is more common in women, aged 45-64, and obese individuals. Diagnosis relies on clinical history and examination, and various treatments target pain relief, though consensus on the most effective modality is lacking. Corticosteroid injections are commonly used but pose risks. This six-month prospective randomized controlled trial with 50 individuals assessed the efficacy of corticosteroid versus placebo injections for resistant PF. Ultrasound-guided injections were administered, and outcomes were measured at 3 weeks and 3 months.: Results indicated significant improvement in pain scores, Ankle and Hindfoot scores, and plantar fascia thickness with corticosteroid injections compared to placebo. No serious adverse events were observed. Corticosteroids aim to reduce inflammation, and studies link decreased plantar fascia thickness to pain relief. Ultrasound guidance enhances precision in delivery. While some protocol limitations exist, this trial contributes valuable insights into the pharmacological effects of corticosteroids in PF treatment, aiding in evidence-based recommendations.

Comparison of Plantar Pressure Distribution and Ultrasonographic and Clinical Features After Application of Different Energy Levels of Extracorporeal Shockwave Therapy in Patients with Plantar Fasciitis: A Randomized, Prospective, Double-Blind Clinical Trial.

The effectiveness of different energy levels used in extracorporeal shockwave therapy (ESWT) has been investigated in previous studies, but controversy remains regarding which energy levels should be used in the treatment of plantar fasciitis. We compared the efficacy of different energy levels used in ESWT in the treatment of plantar fasciitis using plantar fascia thickness and pressure distribution. Between July 2021 and September 2021, a total of 51 patients (71 feet) with plantar fasciitis were randomized into three treatment groups using the sealed envelope method. Group 1 (n = 25) received low energy density (0.09 mJ/mm2), group 2 (n = 25) received medium energy density (0.18 mJ/mm2), and group 3 (n = 21) received high energy density (0.38 mJ/mm2). Each group received three sessions of ESWT at a frequency of 2,000 shocks per minute at 1-week intervals. Patients were evaluated before and after treatment using a visual analog scale (VAS) for pain, the Foot Function Index (FFI), plantar fascia thickness measured by ultrasonography, and plantar pressure distribution. Posttreatment VAS and FFI scores were determined to be significantly lower than the values before treatment in the three groups (P < .001). There were no significant differences among groups in pretreatment and posttreatment values of VAS, FFI, plantar fascia thickness, and pressure distribution (P > .05). No significant differences were found among groups in percentage changes in all of the outcome parameters (P > .05). There was no superiority among low, medium, or high levels of ESWT in terms of pain, foot functions, fascia thickness, and pressure distribution in the treatment of plantar fasciitis.

Platelet-Rich Plasma vs Extracorporeal Shock Wave Therapy in the Treatment of Plantar Fasciitis at 3-6 Months: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Plantar fasciitis (PF) is a common foot disorder with variability in treatment strategy. Two effective management techniques include platelet-rich plasma (PRP) injections and extracorporeal shock wave therapy (ESWT). The purpose of this meta-analysis is to compare the effectiveness of PRP vs ESWT in the management of PF. A systematic search was performed of PubMed, Cochrane, and Google Scholar for randomized controlled trials comparing PRP to ESWT. Studies met inclusion criteria if mean and SDs for visual analog scale (VAS) pain scores and plantar fascia thickness (PFT) were reported. Mean differences were used to compare VAS pain score and PFT between PRP and ESWT. Six randomized controlled trials, comparing a total of 214 subjects in the PRP group and 218 subjects in the ESWT group, were analyzed. A significantly greater statistical improvement was seen in the PRP group in VAS pain (mean difference = -0.67 [95% CI -1.16, -0.18], P = .007) and plantar fascia thickness (PFT) (mean difference = -0.56 [95% CI -0.77, -0.35], P < .001). PRP had a statistically higher pain reduction than ESWT, but the difference does not reach clinical significance in this meta-analysis.

Efficacy and Safety of Platelet-Rich Plasma Injection for Chronic Plantar Fasciitis: A Prospective Study on Functional Restoration and Pain Relief.

Background Heel discomfort and functional impairment are frequently caused by plantar fasciitis, and treating it can be extremely difficult for clinicians and occasionally have unfavorable clinical consequences. Recently, platelet-rich plasma (PRP) has been used as an alternative therapy for plantar fasciitis (PF) to reduce heel pain and improve functional restoration. We evaluated the current evidence concerning the efficacy and safety of PRP as a treatment for PF. Methodology This was a hospital-based prospective study on patients with plantar fasciitis with a symptom duration of six months or more with failed conservative therapy. All patients included in the study were assessed clinically and by a visual analog score (VAS) for heel pain, the Ankle-Hindfoot Scale (AHS) component of the American Orthopedic Foot and Ankle Society (AOFAS) and Foot and Ankle Ability Measure (FAAM) scores before injection, and at three weeks, three and six-months post-PRP treatment follow-up. Ultrasonography (USG) measurement of plantar fascia thickness was done pre-injection and at the six-month follow-up for clinical outcomes and any complications. Results The study included 25 patients with plantar fasciitis, with the majority (48%) in the age group of 21-30 years. Females accounted for 64% of the patientswhile males accounted for 36%. Most patients (56%) had a moderately active daily activity level. The study found that 16 patients had bilateral plantar fasciitiswhile nine had unilateral plantar fasciitis. Among the patients with bilateral plantar fasciitis, a total of 32 heels were affectedwhile the 9 patients with unilateral plantar fasciitis had 9 affected heels. Most female patients (75%) had bilateral plantar fasciitiswhile most male patients (56%) had unilateral plantar fasciitis. Before PRP therapy, both male and female patients reported high pain scores on theVASfor both heels. However, after PRP infiltration, the VAS scores significantly decreased at three weeks, three months, and six months post-injection, indicating pain relief. The AOFAS hindfoot and ankle scores and FAAM scores showed improvement over the follow-up period. Both male and female patients experienced significant improvements in functional outcomes, with increases in AOFAS (p-value 0.45) and FAAM scores (p-value 0.31) at three weeks, three months, and six months post-injection compared to baseline. Statistical analysis revealed a significant decrease in pain scores (73% pain relief), as well as significant improvements in AOFAS scores with an average of 22.33 from baseline (mean = 67.75±9.7) to final follow-up (mean = 90.08±7.9) and FAAM scores with an average of 23.72 from baseline (mean = 49.38±5.2) to final follow-up (mean = 73.10±5.2) after PRP infiltration. Conclusion The outcomes of a single dosage of PRP injections demonstrate clinically and statistically substantial improvements in functional outcome scores, plantar fascia thickness evaluated by USG, and VAS scores for heel pain. According to the results of this study, local PRP injection is an effective treatment for chronic plantar fasciitis.

Morphological and mechanical characteristics of the intrinsic and extrinsic foot muscles under loading in individuals with flat feet

BackgroundThe intrinsic and extrinsic foot softtissue structures that apply force and support the medial longitudinal arch (MLA) have been implicated in the development of flat feet. However, the relationship between the changes in MLA height under increasing load and the morphological and mechanical properties of individual intrinsic and extrinsic foot soft tissue structures is not fully understood. Research questionTo examine the morphological and mechanical characteristics of the foot soft tissue structures in flat feet when subjected to loading. MethodsThis study consisted of two studies focusing on the extrinsic foot muscles (10 normal feet/11 flat feet) and intrinsic foot muscles (14 normal feet/13 flat feet). Images of the extrinsic and intrinsic foot muscles and plantar fascia (PF) under 10%, 50%, and 90% body weight conditions were obtained using ultrasound-based shear-wave elastography. ResultsThe cross-sectional area (CSA) of the peroneus brevis was larger in the flat-foot group than in the normal-foot group under all loading conditions. The CSAs of the intrinsic foot muscles (abductor hallucis, flexor digitorum brevis, and quadratus plantae) and thickness of the PF in the flat-foot group decreased significantly with increasing load. As for mechanical characteristics, the stiffness of the flexor digitorum longus and abductor hallucis was higher in the flat-foot group than in the normal group under high loading conditions. In addition, flat feet with greater flexibility tended to exhibit a greater decrease in PF thickness and smaller increase in stiffness. SignificanceExcessive stretching of the intrinsic foot muscles and PF occurs in flat feet, and excessive contraction of the flexor digitorum longus may counteract the excessive lowering of the foot arch. Therefore, it is necessary to promote the contraction of the intrinsic foot musculature in feet with greater flexibility of the MLA during loading.

Sonographic and clinical effects of manual physical therapy for plantar fasciitis: randomized prospective controlled trial.

This study aimed to evaluate the efficacy of manual physiotherapy on clinical outcomes, morphology of plantar fascia (PF), thicknesses of calcaneal fat pad (CFP) and Kager's fat pad (KFP) with ultrasound imaging in plantar fasciitis (PFS) patients. Also, to evaluate the PF thickness, pain and foot functional outcomes among PFS phases. A randomized controlled trial was conducted on 122 subjects divided into three groups: group A (40 patients with PFS) underwent manual physiotherapy, group B (42 patients with PFS) without any intervention and group C (40 healthy subjects) were matched by age, gender and BMI with each patient in group A and B. The following outcomes were evaluated at baseline and one-month of follow-ups: morphology of PF and thicknesses of CFP and KFP, pain, foot functional limitation. PF thickness was significantly thickened in group A and B compared to group C (P < 0.001). A significant decrease in incidence of PF echogenicity and CFP thickness were found in group A and B compared to group C. Moreover, significant improvement was observed in PF thickness (P < 0.001), PF echogenicity (P < 0.001) and CFP thickness (P = 0.002) in group A at one-month after the treatment. Furthermore, pain intensity and foot functional limitation was significantly improved within group A after receiving the treatment. Significant improvement was noted in PF thickness, pain intensity and foot functional limitation among patients with acute phase. The manual physiotherapy is effective in treatment of PF thickening, hypoechogenicity, pain intensity and activity limitations, particularly in patients associated with acute PFS.

Botulinum toxin A versus platelet rich plasma ultrasound-guided injection in the treatment of plantar fasciitis: A randomised controlled trial

BackgroundPlatelet-rich plasma (PRP) and botulinum toxin type A (BTX-A) injections have proven effective in clinical trials for plantar fasciitis treatment but have not been directly compared. We aimed to compare clinical outcomes in patients undergoing PRP or BTX-A injections. MethodsWe performed a randomised controlled trial (59 patients; 1-year follow-up) to assess efficacy, using pain and functional scales (VAS, AOFAS Hindfoot-scale and FAAM questionnaire) and fascia thickness reduction, in control and single ultrasound-guided BTX-A or PRP injection groups. ResultsThe BTX-A group showed better results at 1-month after treatment. Conversely, the PRP injection was more effective in the long-term, with significant pain reduction and functional improvement. Plantar fascia thickness significantly reduced from months 1 and 3 in the PRP and BTX-A groups, respectively. ConclusionPRP and BTX-A injections are effective in patients with plantar fasciitis with BTX-A achieving better short-term pain reduction and PRP better long-term results.
