Effects of plantar fascia stiffness on the biomechanical responses of the ankle–foot complex

Objective. The aim of this study was to investigate the effects of surface stiffness on multisegment foot kinematics and temporal parameters during running. Methods. Eighteen male subjects ran on three different surfaces (i.e., concrete, artificial grass, and rubber) in both heeled running shoes (HS) and minimal running shoes (MS). Both these shoes had dissimilar sole profiles. The heeled shoes had a higher sole at the heel, a thick base, and arch support, whereas the minimal shoes had a flat base sole. Indeed, the studied biomechanical parameters responded differently in the different footwear during running. Subjects ran in recreational mode speed while 3D foot kinematics (i.e., joint rotation and peak medial longitudinal arch (MLA) angle) were determined using a motion capture system (Qualysis, Gothenburg, Sweden). Information on stance time and plantar fascia strain (PFS) was also collected. Results. Running on different surface stiffness was found to significantly affect the peak MLA angles and stance times for both HS and MS conditions. However, the results showed that the joint rotation angles were not sensitive to surface stiffness. Also, PFS showed no relationship with surface stiffness, as the results were varied as the surface stiffness was changed. Conclusion. The surface stiffness significantly contributed towards the effects of peak MLA angle and stance time. These findings may enhance the understanding of biomechanical responses on various running surfaces stiffness in different shoe conditions.

Intrinsic Foot Muscles

The human foot is a flexible structure characterized by a pronounced medial longitudinal arch (MLA) that compresses and recoils during running. That process is actively driven by the intrinsic foot muscles and requires a proper stability of the MLA. This introduces the concept of foot core stability. Because the intrinsic foot muscles are often neglected by clinicians and researchers, the purpose of this article is to provide some guidelines for incorporating foot core training in prevention or rehabilitation programmes for runners. The intrinsic foot muscles play a key role in postural control and maintain balance during single leg stance by controlling the height of the MLA and the foot pronation. During running, these muscles lengthen eccentrically during the absorption phase and subsequently shorten as the arch recoils during the propulsive phase, functioning in parallel to the plantar fascia. As a consequence, the dysfunction or weakness of the MLA active support may lead to injuries (e.g. plantar fasciopathy, Achilles or Tibialis posterior tendinopathy, metatarsalgia or medial tibial stress syndrome), due to numerous biomechanical cascades and mechanisms. In order to counteract or prevent these impairments, there are two ways for enhancing the foot core stability. Firstly in terms of volitional control of the intrinsic foot muscles, the “short foot exercise” must be practiced. Secondly strengthening sessions using neuromuscular electrical stimulation of these muscles seem to be a promising strategy in order to support the MLA and control the pronation during running. Practically, the foot core strengthening protocol may beneficiate not only the runners affected by excessive pronation related injuries but also those who sustained a long term lower limb injury and may be affected by a detraining process. In addition we warmly recommend integrating this protocol in any lower limb injury prevention programme or strength and conditioning plan for runners.

Background:Enthesitis is the clinical hallmark of spondylarthritis. It refers to the inflammation of joint attach in the bone. Several sites enthesitis may be affected, and a wide variety of scoring systems were available.Objectives:We aimed to determine the prevalence of axial enthesitis in the anterior chest wall (ACW), and its correlation with peripheral sites especially, the Achilles tendon (AT).Methods:We conducted a prospective study including patients with SpA according to the ASAS criteria. Sociodemographic data, as well as disease characteristics, were recorded. The Maastricht Ankylosing Spondylitis Enthesitis Score (MASES) was used to assess clinical entheses (first and seventh costochondral joints, posterior superior iliac spine, anterior superior iliac spine, iliac crest, and Achilles tendon insertion). The presence of enthesitis on the US was then assessed in the right and left sternoclavicular (SCJ), manubriosternal (MSJ) joints, as well as in the AT, using Esaote My Lab 50.Results:The study included 47 patients with SpA: axial (n=26), axial and peripheral (n=21). There was a female predominance (sex ratio: 0.2). The mean age was 42.2 years ± 12.6 [11-70]. The age of onset of the disease was <40 years in 59.6% of cases. Tenderness in entheseal sites was found in 63.8% of patients, especially in the plantar fascia and AT (32.7%, 6%, respectively). The mean MASES score was 2.9 [0-13]. Clinical ACW involvement (29.1%) was at follows: 1st right chondro-sternal joint (CSJ) (19.1%), 1st left CSJ (25.5%), 7th right CSJ (27.7%) and 7th left CSJ (31.9%).US involvement of the ACW was 14.3%. Enthesitis of the AT was found in 70% of cases on US examination. ACW US involvement was correlated neither to the BMI nor to MASES score (p=0.16, p=0.6 respectively). Similarly, there was no correlation between the presence of US ACW enthesitis and clinical nor the US AT enthesitis (p=0.09, p=0.209, respectively).Conclusion:Our study showed that ACW enthesitis is frequent in SpA, especially by US screening. This axial enthesitis, don’t necessarily reflect a simultaneous clinical or US involvement of the peripheral entheses. Further studies are needed to characterize this subtype of SpA.References:[1]Verhoeven F, Guillot X, Godfrin-Valnet M, Prati C, Wendling D.

Design Chronic plantar fasciitis (PF) is a common cause of chronic heel pain, with different conventional treatment options. In this randomized clinical trial, the effect of ultrasound-guided injection of dextrose versus corticosteroid in chronic PF was evaluated and compared. Methods A total of 44 patients suffering from chronic PF who visited the physical medicine and rehabilitation clinic were enrolled in the study. Two table-randomized groups were formed. They received an ultrasonography-guided, single injection of either 40 mg methylprednisolone or 20% dextrose. Numeric Rating Scale (NRS), Foot and Ankle Ability Measure questionnaire with 2 subscales, Activities of Daily Living (FAAM-A) and Sports (FAAM-S), along with ultrasonographic parameters were evaluated before and at 2 and 12 weeks after the injection. Results. A total of 40 participants completed the study. Both interventions significantly improved pain and function at 2 and 12 weeks postinjection. After 2 weeks, compared with the dextrose prolotherapy, the corticosteroid group had significantly lower daytime and morning NRS scores (2.55 vs 4.1, P = .012, and 2.75 vs 4.65, P = .004), higher FAAM-S (66.84 vs 54.19; P = .047), and lower plantar fascia thickness at insertion and 1 cm distal to the insertion zone (3.89 vs 4.29 mm, P = .004, and 3.13 vs 3.48 mm, P = .002), whereas FAAM-A was similar in both groups ( P = .219). After 12 weeks, all study variables were statistically similar between corticosteroid and dextrose prolotherapy groups. No injection-related side effects were recorded in either group. Conclusion Both methods are effective. Compared with dextrose prolotherapy, our results show that corticosteroid injection may have superior therapeutic effects early after injection, accompanied by a similar outcome at 12 weeks postinjection.

Background:Entheseal involvement is a frequent and distinctive feature of psoriatic arthritis (PsA), often under diagnosed. It is especially associated with nail involvement. Because clinical examination is not sensitive enough for the detection of early signs of this involvement, US may be considered as an alternative imaging technique in the diagnosis of enthesopathy.Objectives:The aim of the present study is to evaluate US entheses abnormalities in PsA and their correlation with clinical characteristicsMethods:The study included patients diagnosed with PsA according to the CASPAR criteria. They underwent a thorough clinical examination with special regard to the presence of enthesitis using the Spondyloarthritis Research Consortium of Canada (SPARCC) Enthesitis Index.The US study bilaterally explored entheses at six sites: proximal plantar fascia, distal Achilles tendon, distal and proximal patellar tendon insertion, distal quadriceps tendon and distal brachial triceps tendon. We evaluated the following elemental lesions of enthesis at each site: thickness and structure of the tendon, calcifications, bursae, erosions, power Doppler signal in bursa or enthesis full tendon.Results:Of the 33 patients, 39.4 % were male. The mean age was 51.2±12.5 years. The mean disease duration was 13.5±10.2 years.The mean DAPSA was 22.8± 19.7 [0.1-84.5]: remission(n=9), low activity (n=5),moderate activity (n=11),high activity(n=8).At inclusion, 11 patients (33.4%) patients presented with psoriatic onychopathy (45 fingernails) with a mean mNAPSI of 14.1±16. Out of the 528 entheseal sites, 92 were tender at the palpation (17,4%) with a mean SPARCC at 2.87.A total of 396 entheseal sites were examined by US. In 140 of them (35.35%), US found at least 1 sign indicative of enthesopathy. The most affected tendon was the distal Achilles tendon (42/396), followed by proximal plantar fascia (32/396), distal patellar tendon (20/396), quadriceps tendon (20/396), distal brachial triceps tendon(14/396) and finally proximal patellar tendon (12/396).The most common elemental lesions were enthsophytes (176), erosions (114) and calcifications (50).We found a positive correlation between age and both calcification (r=0,4, p=0.021) and enthesophytes (r=0.479, p=0.005).We found a positive correlation between enthesophyte and the tender and swollen joints count (r= 0.352, p=0.045, r=0.378, p=0.03) and the SPARCC score (r=0.397, p=0.022).Patients with higher BASDAI had thicker tendons (r=0.355, p=0.05).Patients with nail dystrophy had more bursitis and erosions.US scores did not correlate with sexe, disease duration and disease activity measures (ASDAS, DAPSA, DAS28 and PASI). Patients with subclinical entheseal involvement didn’t have higher inflammatory biomarkers (ESR, CRP).Conclusion:US subclinical enthesopthy are not rare in psoriatic arthritis, in particular in patients with active disease.Clinical nail involvement was associated with bursitis and erosions. New studies including larger study groups are required to verify the findings of the present studyDisclosure of Interests:None declared
