Custom-Made Foot Orthoses Reduce Pain and Fatigue in Patients with Ehlers-Danlos Syndrome. A Pilot Study

Effect of Foot Orthoses and Footwear in People with Rheumatoid Arthritis: An Updated Systematic Review

BACKGROUND/OBJECTIVES

Rheumatoid arthritis is a chronic, systemic, inflammatory disease of an autoimmune nature that causes pain and disability in affected patients. Foot pain has become a challenge due to its negative impact on physical function. The objective of this updated systematic review is to describe the effect of foot orthoses and/or footwear in patients with rheumatoid arthritis and foot problems.

METHODS

Scopus, PubMed, CINALH, WOS, and Dialnet were searched for all articles published from January 2013 to September 2024. Inclusion criteria included randomised clinical trials and crossover trials (level of evidence I), published within the last 10 years, involving adults with a diagnosis of rheumatoid arthritis, with no restrictions on gender, race, or ethnicity. All studies that addressed the use of foot orthoses and/or shoe therapy in any type of comparison between these interventions were considered relevant. Review Manager was used to carry out the bias analysis of the selected studies. The reporting was based on the new PRISMA guidelines.

RESULTS

A total of 9 relevant articles were selected from an initial sample of 438. These articles analyse and compare the effectiveness of various types of foot orthoses in reducing pain, functional limitation, and disability, as well as improving balance and kinetic and kinematic parameters affected by rheumatoid arthritis.

CONCLUSIONS

Foot orthoses reduce pain and disability in rheumatoid arthritis, improving balance and kinematic parameters. However, no significant improvements in the patients' functionality and walking ability have been demonstrated. Customised ones with good arch control, heel reinforcement, and metatarsal pad are more effective. No results on the impact of footwear on patients with rheumatoid arthritis have been found in the last 10 years. This systematic review was registered in PROSPERO (CRD42023405645).

Foot Pain and Disability in Women with Rheumatoid Arthritis, Ehlers-Danlos Syndrome and Systemic Lupus Erythematosus: Relationship with Quality of Life

The aim of this work was to investigate the relationship foot pain and foot disability have with HRQoL in groups of women with RA, SLE and EDS, in comparison with a control group. A cross-sectional study was carried out with females with one of these conditions and a control group. The SF-12 questionnaire was used to collect data about quality of life. The type of foot was classified according to the footprint and the foot posture index. A total of 156 patients and 47 controls participated in the study (N = 203). Neither pain nor foot posture were different between groups. The physical and mental components of SF-12 were worse in rheumatoid arthritis and Ehlers-Danlos syndrome patients, and the physical component was worse in systemic lupus erythematosus patients, compared to controls. A significant difference was also observed in the mental component between systemic lupus erythematosus and Ehlers-Danlos syndrome patients, the latter having the lowest values among the groups. We can conclude that women with rheumatoid arthritis, Ehlers-Danlos syndrome, systemic lupus erythematosus and foot pain perceive a worse quality of life. There are no significant changes in foot posture. Pain and health-related quality of life are independent of foot posture.

The Impact of Podiatric Intervention on the Quality of Life and Pain in Children and Adolescents with Hypermobility

The purpose of this study was to evaluate the effect of custom-made orthotics on pain, health-related quality of life (HRQoL), function and fatigue in children and adolescents with generalised joint hypermobility (GJH) and lower limb pain. Fifty-three children aged 5-18 years were fitted with custom-made polypropylene orthotics. Visual analogue scale (VAS) assessed lower limb pain severity, Paediatric Quality of Life Inventory assessed HRQoL and fatigue and six-minute walk test (6 MWT) measured functional endurance at baseline, at 1 month and 3 months post-intervention. A mixed model including a random intercept for participant and a fixed effect for time was used to assess differences in outcomes over time. Fifty-two children completed the study (mean age 10.6-years). Children reported significantly reduced pain (mean VAS reduction -27/100, 95%CI: -33, -21), improved HRQoL (mean total improvement 11/100, 95%CI: 7, -15), functional capacity (mean 6MWT improvement 27 m, 95%CI: 18, -36) and fatigue (mean total improvement 13/100, 95%CI: 9, -17) after 1 month of wearing the custom-made orthotics. From 1 month to 3 months there was further statistically but not clinically significant reduction in pain while benefit on other outcomes was maintained. In this study, children with GJH reported reduced lower limb pain, improved HRQoL, functional endurance and fatigue after a month post-fitting of custom-made orthotics which was maintained over a 3 month period. Orthotics were well-tolerated with no serious adverse events reported.

Developmental Foot Deformities in Patients with Connective Tissue Disorders

»

Foot deformities make up a large percentage of all orthopaedic complaints in patients with Down syndrome, Marfan syndrome, Ehlers-Danlos syndrome, Larsen syndrome, and osteogenesis imperfecta.

»

Some common causes of foot deformities in these conditions include increased ligament laxity, hypotonia, and hypermobility of the joints.

»

Treatment options for syndromic foot deformities include the use of foot orthoses, physical therapy, bracing, and various surgical procedures.

»

There is limited evidence supporting the use of surgical intervention to correct foot deformities associated with Down syndrome, Marfan syndrome, Ehlers-Danlos syndrome, Larsen syndrome, and osteogenesis imperfecta. Therefore, further research is needed to determine the short-term and long-term outcomes of these procedures.

Multidisciplinary chronic pain management strategies in patients with Ehlers-Danlos syndromes

Ehlers-Danlos syndromes (EDS) are a group of disorders characterized by abnormal connective tissue affecting several organ systems. Patients with the hypermobile type of EDS (hEDS) commonly experience chronic pain which can present as musculoskeletal pain, fibromyalgia, neuropathic pain or abdominal pain. The effective management of chronic pain in hEDS patients is a challenge. This study reviews two cases of chronic pain in hEDS patients and the multimodal treatment regimen used along with peripheral nerve stimulation for shoulder and knee pains, never before reported in hEDS patients. Since hEDS associated chronic pain is multifactorial in origin, treatment requires a multidisciplinary approach which includes physical therapy, psychotherapy, pharmacotherapy and interventional pain procedures such as trigger point injections, peripheral nerve block, radiofrequency ablation and peripheral nerve stimulation.

A Comprehensive Review: Chronic Pain Sequelae in the Presence of Ehlers-Danlos Syndrome

PURPOSE OF REVIEW

Patients diagnosed with Ehlers-Danlos syndromes (EDS), and especially those with the hypermobility subtype, often experience a diverse range of acute and chronic pain conditions throughout their lifetime. These can present in a variety of different phenotypes and comorbidities, making it difficult to develop structured treatment protocols. This review seeks to summarize the current literature to address old and novel treatments for EDS.

RECENT FINDINGS

Historically, medications and surgery have been used to treat patients with EDS but with low efficacy. Newer therapies that have shown promising effects for both decreasing pain and increasing quality of life include physical/occupational therapy, transcutaneous electrical nerve stimulation units, trigger point injections, low-dose naltrexone, and laser therapy. In addition, addressing the psychosocial aspects of pain with EDS through methods like cognitive behavioral therapy and patient education has shown to be vital in minimizing pain. Most research also emphasizes that pain management should not only focus on pain reduction, but on helping reduce symptoms of hypermobility, central sensitization, and fatigue to make an impactful difference. Research on pain in EDS is still limited with good clinical practice guidelines often limited by poor sample size and lack of clinical studies. Treatment options should be structured based on the specific type of pain pathology and presenting symptoms of each patient and their comorbidities. Future research should attempt to prioritize larger sample sizes, clear definitions of EDS subtypes, randomized trials for treatment efficacy, and more studies dedicated to non-musculoskeletal forms of pain.

Semi-automatic measurements of foot morphological parameters from 3D plantar foot scans

Background

Foot healthcare research is focusing increasingly on personalized orthotic and prosthetic devices to address patient-specific morphology and ailments. Customization requires advanced 3D image processing tools to assess foot and leg geometrical parameters and alterations. The aim of this study is to present a new software for the measurement of the foot shape from 3D scans of the foot plantar surface.

Methods

A Kinect-based scanning device was used to acquire the 3D foot shape of 44 healthy subjects. A software was developed in Matlab to measure the foot main morphological parameters from foot scans. Principal Component Analysis was used to orientate the foot scans with respect to the same reference system. Accuracy, via percentage errors and Bland-Altman plots, and correlation of the software-based foot parameters were assessed against manual measurements. A normalized Arch Volume Index (nAVI) was proposed and correlated to the traditional Arch Index. Test-retest Intraclass Correlation Coefficient was used to assess the inter-session repeatability of foot measurements.

Results

The average percentage error between software and manual measurements was 1.2 ± 0.8% for foot length, 9.1 ± 3.7% for foot width, 22.3 ± 13.5% for arch height and 23.1 ± 12.7% for arch depth. Very strong correlations were observed for foot length (R = 0.97) and foot width (R = 0.83), and strong correlations for arch height (R = 0.62) and arch depth (R = 0.74). nAVI was negatively correlated to the Arch Index (R = -0.54). A small difference was found between software and manual measurements of foot length (Δ = 0.92 mm), a software overestimation of foot width (Δ = 8.6 mm) and underestimation of arch height (Δ = -1.4%) and arch depth (Δ = -11%). Moderate to excellent repeatability was observed for all measurements (0.67–0.99).

Conclusions

The present software appears capable to estimate the foot main morphological parameters without the need for skin markers or for identification of anatomical landmarks. Moreover, measurements are not affected by the foot orientation on the scanning device. The good accuracy and repeatability of measurements make the software a potentially useful operator-independent tool for the assessment of foot morphological alterations and for orthotics customization. nAVI may be used for a more realistic classification of foot types when 3D foot images are available.

Practical management strategies for benign hypermobility syndromes

PURPOSE OF REVIEW

Patients with symptomatic hypermobility syndrome such as hypermobile Ehlers-Danlos syndromes (hEDS) and hypermobility spectrum disorders (HSD) commonly present to rheumatologists with joint pain and functional disability. Providers often have difficulty with diagnosis due to a lack of knowledge on the range of associated manifestations and the available therapeutic modalities. This review will discuss recent updates on diagnostic measures and treatment options for rheumatologists to help patients navigate hEDS/HSD.

RECENT FINDINGS

This article describes newer diagnostic measures and assessment of hEDS/HSD manifestations. Evidence supporting physical therapy and occupational therapy is provided, as well as recent updates on assistive devices, compressive garments, orthoses, and surgical interventions. Given patient heterogeneity specific guidance about the amount and type of therapies required to produce a beneficial effect is lacking. Treatment should be individualized, and many of the studies focus on regional joint complaints rather than a whole-body approach.

SUMMARY

Physical therapy and occupational therapy remain the cornerstone of treatment.

The reliability, validity, and sensitivity of the Edmonton Frail Scale (EFS) in older adults with foot disorders

The Edmonton Frail Scale (EFS) is an index employed to measure alterations related to frailty. The main objective in this research was to develop the EFS short-form (EFS-SF) and to evaluate its validity, reliability, and sensitivity to predict frailty disability outcomes in elderly patients with foot disabilities.

RESULTS

Exploratory factor analysis (EFA) of the EFS-SF revealed the presence of three components, as in the original EFA. There were significant differences (p < 0.05) in the study population for several of the EFS and 5-item FRAIL scale indicators. The highest correlation (Pearson R = 0.871; p < 0.001) was found for the first component of the EFS-SF. Finally, the Cronbach alpha was 0.864 which indicated a high level of internal consistency.

CONCLUSION

The EFS-SF is a reliable and valid instrument to measure frailty in patients with and without foot disabilities.

METHOD

A cross sectional descriptive study was carried out. The study population was aged over 60 years (n = 66) and comprised 29 men and 37 women. Frailty disorders were registered by using the EFS, 5-item FRAIL scale, and the Geriatricians' Clinical Impression of Frailty (GCIF) scale. EFA was employed to locate potential constituents of the EFS, with scores ranging from 0.596 to 0.946 for each of the sub scales: (1) cognitive and general health status; (2) medication and nutrition status; and (3) functional and physiological status, thus revealing that the EFS-SF comprised three components, a reduction compared to the nine in the original EFS.

Psychosocial Influence of Ehlers-Danlos Syndrome in Daily Life of Patients: A Qualitative Study

(1) Background: Ehlers–Danlos syndrome is a heterogeneous group of connective tissue disorders causing pain, fatigue, and disabilities; it has several implications for patients who suffer from this disease. The major clinical manifestations of EDS include joint hypermobility, skin hyperextensibility, and generalized connective tissue fragility. This research aims to explore their perceptions and experiences about the phycological and social spheres. (2) Methods: Semistructured interviews were carried out. Participants were encouraged to talk about issues related to their disease by asking open-ended questions in one to one interview. The interview guide included questions to identify the syndrome’s influence on the social and psychological life of patients All interviews were audio recorded, fully transcribed, and analyzed using the phenomenological theoretical framework. The method of analysis was the thematic interpreting of perspectives and approaches. (3) Results: 31 individuals were proposed to participate in this study. Five patients refused to participate, so a total of 26 interviews were performed. Six themes ((1) Pain and its consequences on a daily basis; (2) The need to name the problem: the diagnosis; (3) Restructuring leisure and social relationships; (4) Limitations due to economic conditions; (5) Psychological impact of the disease situation; (6) Professional limitations) and four subthemes ((1) The value of partner support; (2) The weather influence on social plans; (3) Physical exercise and illness; (4) Support groups) emerged from the data. (4) Conclusions: This study revealed the impact of the syndrome on the social and daily life of patients, and not only in a physical level, but also in a psychological and social approach. These findings allow healthcare providers to know more about this disease in order to support and give advice to patients about the changes they will have to make.
