Objectively Assessed Foot and Ankle Characteristics in Patients With Systemic Lupus Erythematosus: A Comparison With Age- and Sex-Matched Controls

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.

Effectiveness of custom-made functional foot orthoses versus flat cushioning insoles on pain in patients with systemic lupus erythematosus

OBJECTIVE

To determine the effect of foot orthoses on pain, disability and foot functionality in patients with Systemic Lupus Erythematosus.

DESIGN

Randomized clinical trial.

SETTING

University Podiatric Clinical Area.

SUBJECTS

Patients with systemic lupus erythematosus.

INTERVENTIONS

Patients were randomly assigned to either group A, which received custom-made functional foot orthoses, or group B, which received flat cushioning insoles, for three months.

MAIN MEASURES

The primary outcome was foot pain, measured by 11-point numeric pain rating scale. Foot functionality and foot-related disability were evaluated using the foot function index, the Manchester foot pain and disability, at the beginning and at days 90.

RESULTS

Sixty-six participants (age 47.3 ± 11.9 years) suffering from foot pain, received either the custom-made foot orthoses (N = 33) or the flat cushioning insoles (N = 33). For the analysis of the data, only participants who had finished the follow-up period (90 days) were included. None statistically significant difference between groups were found. In group A, all variables showed statistically significant differences when comparing the initial and final measurements. Pain showed 6.8 ± 1.6 and 4.2 ± 2.9 in group A, at baseline and at 90 days, respectively, group B showed 6.5 ± 1.5 and 4.7 ± 3.0 at baseline and at 90 days, respectively.

CONCLUSION

Both groups showed a reduction in foot pain. This study suggests that not only controlling the foot function, but providing cushioning to the foot, may have positive effects to manage foot pain in patients with systemic lupus erythematosus.

An evaluation of podiatry service use for people with inflammatory rheumatic diseases: a review of a rheumatology podiatry clinic in Aotearoa New Zealand

Background

Foot problems, including foot pain, structural deformities, skin and nail lesions, and footwear difficulties, are common in people with inflammatory rheumatic diseases. However, dedicated podiatry services are limited, including in Aotearoa New Zealand. This study aimed to evaluate the podiatry service use for people with inflammatory rheumatic diseases who attended a specialist podiatric rheumatology clinic in Aotearoa New Zealand.

Methods

This retrospective review included people with an inflammatory rheumatic disease who attended the Auckland University of Technology Podiatric Rheumatology Clinic between 2010 and 2021. Data were extracted manually from patients’ clinical records, including variables relating to patient characteristics, appointment details, presenting complaint, assessments performed, and treatments provided.

Results

From 2010 to 2021, 157 people with inflammatory rheumatic diseases attended 1570 appointments. The most common presenting concern was foot pain (reported by n = 121, 77.1% patients during at least one appointment), followed by skin/nail lesions (n = 98, 62.4%) and footwear/orthotic needs (n = 90, 57.3%). A range of podiatric interventions were provided to address foot-care needs, in which education (n = 151, 96.2%) and general skin/nail care (n = 107, 68.2%) were the most common treatments provided. The majority of patients also received footwear interventions at some point during their period of service provision (n = 96, 61.1%), followed by orthoses, other padding/offloading devices, wound care, exercise prescription and referrals to other health professionals.

Conclusions

This is the first study to review podiatric service provision for people with inflammatory rheumatic diseases attending a specialist podiatric rheumatology clinic in Aotearoa New Zealand. The results of this study have shown that a podiatry clinic dedicated to people with inflammatory rheumatic diseases addresses the wide range of foot problems through an extensive provision of treatment services.

Work participation, mobility and foot symptoms in people with systemic lupus erythematosus: findings of a UK national survey

Objective

The aim of this study was to investigate whether foot and lower limb related symptoms were associated with work participation and poor mobility in people with Systemic Lupus Erythematosus (SLE).

Method

A quantitative, cross-sectional, self-reported survey design was utilised. People with SLE from six United Kingdom (UK) treatment centres and a national register were invited to complete a survey about lower limb and foot health, work participation and mobility. Data collected included work status and the prevalence of foot symptoms. The focus of the analyses was to explore potential associations between poor foot health work non-participation.

Results

In total, 182 useable surveys were returned. Seventy-nine respondents reported themselves as employed and 32 reported work non-participation. The remaining were retired due to age or reported work non-participation for other reasons. Work non-participation due to foot symptoms was significantly associated with difficulty walking (p = 0.024), past episodes of foot swelling (p = 0.041), and past episodes of foot ulceration (p = 0.018). There was a significant increase in foot disability scores amongst those not working (mean 18.13, 95% CI: 14.85–21.41) compared to those employed (mean 10.16, 95% CI: 8.11–12.21).

Conclusions

Twenty-nine% of people with SLE reported work non-participation because of lower limb or foot problems. Our results suggest that foot health and mobility may be important contributors to a persons’ ability to remain in work and should be considered as part of a clinical assessment.
