Concurrent Validity of the Foot Health Status Questionnaire and Study Short Form 36 for Measuring the Health-Related Quality of Life in Patients with Foot Problems

Portuguese validation of the foot health status Questionnaire in patients with diabetic foot disease

PURPOSE

This study aims to adapt and validate the Foot Health Status Questionnaire, developed by Bennett et al., in Portuguese patients with diabetic foot.

MATERIALS AND METHODS

A cross-sectional study was conducted with 143 patients with diabetic foot. A principal component analysis with oblique rotation and a confirmatory factor analysis using structural equation modeling were performed.

RESULTS

The Portuguese version of the FHSQ (FHSQ-PT) in patients with diabetic foot remains equal to the original version, although with all factors correlated with each other. All scales presented high internal consistency values (pain: ω = 0.884; function: ω = 0.890; general foot health: ω = 0.910; and footwear: ω = 0.702), except for the footwear scale, although with a minimum acceptable coefficient. The FHSQ-PT scales showed good convergent validity and good discriminant validity. The FHSQ-PT scales were also able to discriminate between male and female patients as well as between patients with an active diabetic foot ulcer from those who did not.

CONCLUSIONS

The results of the validated FHSQ-PT for Portuguese patients with diabetic foot showed good psychometric properties, being a useful, objective, and small instrument that may be used in clinical practice by health professionals without consuming too much time.

＜Editors' Choice＞ The relationship between preoperative foot alignment and postoperative outcomes in patients who underwent initial total knee arthroplasty

We compared the relationship between foot alignments and quality of life in patients who underwent initial total knee arthroplasty (TKA). Among the patients with knee osteoarthritis (KOA) who underwent TKA from May 2015 to May 2017 at our hospital, we focused on those in whom weight-bearing foot radiographs had been evaluated preoperatively. The hallux valgus angle and Meary angle were measured by preoperative radiography, and those with hallux valgus angles of 20 degrees or more were classified into the hallux valgus (HV) group, and those with Meary angles of 4 degrees or more into the high arch (HA) group. Also knee and ankle range of motion, knee pain Visual Analog Scale, and the 36-item short-form health survey (SF-36) were measured preoperatively and at discharge, and the amount of these changes was compared in the presence/absence of HV and HA. Regarding HV, there were no significant differences in any of these items between the HV and non-HV groups. However, the SF-physical function was significantly lower in the HA group than in the normal group. In addition, ankle dorsiflexion was lower in the HA group than that in the normal group, although this difference was not statistically significant. There was little improvement of the ankle dorsiflexion, and it was associated with deterioration of the physical function items of SF-36. In total knee arthroplasty patients with HA, physical therapy of the ankles and feet, as well as of the knees, was considered to enhance the improvement of physical function.

Assessment and indicators of hallux limitus related with quality of life and foot health in school children

Background

Functional Hallux Limitus (FHL) is a dynamic foot dysfunction characterized by a limitation of hallux dorsiflexion when the first metatarsal head is under load. FHL plays a role in the development of osteoarthrosis in the first metatarsophalangeal joint (IMTPJ). Forefoot disorders can significantly impact an individual's quality of life, leading to dysfunction and pain. The aim of this project was to evaluate the quality of life of school-aged individuals with and without FHL using the Foot Health Status Questionnaire (FHSQ).

Methods

A case-control study was conducted to evaluate the outcomes in paediatric age. A total sample of 116 children between 6 and 12 years old was used to conduct this research. The sample was divided into two groups: (i) the healthy group (n = 58) and the FHL group (n = 58). The FHSQ was completed and the FHL test was performed in a seated position to classify the patients into the selected group.

Results

Non-significant changes were observed when the mean values of the FHSQ domains were compared between the groups with and without FHL, except for the "general foot health" domain (p = 0,024) associated with the specific foot health section (section 1) of the Questionnaire. For the domains linked with the general well-being section (section 2), there was not a statistically difference in the mean of the scores obtained between the two school-aged groups with and without FHL, being slightly lower in the group with the presence of FHL for the overall health and physical function domains. Both the healthy and case groups obtained and identical range of scores (10-100) for the "foot pain" domain. Nevertheless, the mean of the score was lower for the participants with FHL.

Conclusions

The perception of the quality of general foot health was poorer in the school-aged group with FHL. Variables such as foot pain and footwear are likely contributors influencing the perception of foot health quality. The school-aged population with FHL faces a decline in the quality of foot life. Ensuring adequate foot control in children and implementing future foot programs for this population are imperative for enhancing school children's perception of foot health and managing the development of pain and footwear-related issues.

Effect of foot health-related quality of life in rural population: A case-control study

BACKGROUND

Foot health problems can affect quality of life and general health producing a source of discomfort and pain. Low levels of foot health-related quality of life (HRQoL) are present in patients with foot disabilities, such as hallux valgus, plantar fasciitis, or minor toe deformities.

OBJECTIVE

The objective was to analyze the foot health status in patients with and without foot problems in a rural population and its relationship with quality of life.

MATERIAL AND METHODS

A prospective case-control study was developed with a sample of 152 patients, 76 subjects with podiatric pathologies and 76 without, in a rural population. HRQoL was measured through the SF-36 Health Questionnaire in the Spanish version.

RESULTS

The case group had a mean age of 49.18 ± 14.96 and the control group 44.16 ± 11.79. Regarding the score of the lowest levels of quality of life related to foot problems, the case group compared to the controls showed: for physical function (79.86 ± 26.38 vs. 92.63 ± 11 0.17, p < 0.001); for the physical role (73.68 ± 41.00 vs. 88.48 ± 27.51, p < 0.0022); for body pain (45.81 ± 27.18 vs. 73.68 ± 41.00, p < 0.035); and for general health (60.36 ± 30.58 vs. 68.71 ± 18.52, p < 0.047). The differences between groups were analyzed using the Mann-Whitney U test, which showed statistical significance (P < 0.05).

CONCLUSIONS

In the rural population, people with foot pathologies present a worse quality of life compared to those who do not present foot pathology, especially for the health domains: physical function, physical role, body pain and health general.

Foot health and quality of life among adults in Riyadh, Saudi Arabia: a cross-sectional study

BACKGROUND

Foot conditions are frequent among the Saudi population. However, little is known regarding the effects of foot health on quality of life among the general Saudi population. This study aimed to assess foot health status, general health, and quality of life among the population of Riyadh using the Foot Health Status Questionnaire (FHSQ).

METHODS

In this cross-sectional study, out of the total number of participants approached, using a preset questionnaire, by trained medical students to participate in this study, 398 met the inclusion criteria. The questionnaire started with an informed consent followed by a set of questions regarding the sociodemographic and past medical characteristics of the participants. Foot health and overall health were assessed using a FHSQ.

RESULTS

A statistically significant positive correlation was observed between all the FHSQ domains, except for footwear. The strongest correlation was observed between foot pain and foot function, foot pain and general foot health, and foot function and general foot health. A statistically significant positive correlation was observed between general foot health and general health, vitality, social function. Our results also showed that foot pain, general foot health, vitality, and social function scores were significantly lower in women as compared to men.

CONCLUSION

Significant positive correlation was observed between poor foot health and declining quality of life; thus, it is crucial to increase society's awareness of the importance of medical foot care and continuous follow-up and consequences if left unrecognized and untreated. This is a major domain that can improve the well-being and quality of life of a population.

The effect of exercise on the quality of life in an academic environment

Regular physical activity has a direct association with an improvement in perceived health-related quality of life (HRQL). Because many Saudis are reportedly inactive, Imam Abdulrahman bin Faisal University established a walking challenge for all university employees to encourage a better lifestyle and to promote health awareness. This study aims to measure the differences in the participants' HRQL scores before and after the challenge. A before and after study was conducted using HRQL survey that was sent to all university employees before the implementation of a pedometer-based walking challenge at the study setting, and after the challenge ended. A randomized snowball sample method was used to recruit participants. The differences in the overall HRQL before and after the challenge were calculated. A RAND SF20-items scale was used to measure the participants' HRQL scores, along with other information such as academic qualifications. Most of the participants were between 31 and 50 years old, and 40% were males. There was a statistically significant difference in the overall HRQL scores before and after the walking challenge intervention. The HRQL score increased from 50.77 before the challenge to 55.53 after the challenge (paired t-test = - 4.322, P < 0.0001). An odds ratio (OR) showed that the odds of having higher HRQL scores increased by 88% after the walking challenge, compared to before the walking challenge (OR = 1.88; 95% CI = 1.269-2.809; P = 0.002). Physical activity by itself can improve a community's overall health and quality of life. Similar interventions are encouraged in all public and private sectors in the country.

Impact of Multiple Sclerosis on Foot Health and Quality of Life: A Prospective Case-Control Investigation

Objectives: To assess quality of life or factors related to the foot and general health and to determine the impact taking into account foot health status in people with multiple sclerosis (MS). Methods: 50 subjects with MS and 50 healthy subjects were studied using the Foot Health Status Questionnaire, that is a validated and is reliable tool was used to assess foot health and quality of life. This instrument comprise four domains for evaluate the foot health (foot function, foot pain, footwear and general foot health) in the first section and for measure the general health comprise four domains (general health, physical activity, social capacity and vigor) for second section and was use for all participants. Results: In both groups of the sample, 50% (n = 15) were men and 50% (n = 35) women, and the mean age in the case group was 48.04 ± 10.49 and the control group was 48.04 ± 10.45 were recruited. A statistically significant difference (p < 0.05) was shown for foot function, general foot health, general health, physical activity and vigor domains, stating that people with MS have a lower related to foot health (lower FHSQ scores) compared to healthy subjects who have higher FHSQ scores. There were no statistically significant differences (p > 0.05) for the scores of the other domains of the FHSQ (foot pain, footwear and social capacity). Conclusion: Patients with MS suffer a negative impact on the quality of life related to foot health, which appears to be associated with the chronic disease.

Impact of foot health behavior among ethnic minority populations: A cross-sectional population-based study

OBJECTIVE

To analyze the impact of the foot health and health behavior and the characteristics of outdoor footwear among minority ethnic groups.

DESIGN AND MEASURES

A cross-sectional study design using the Foot Health Status Questionnaire: foot pain, foot function, shoe, general foot health, general health, physical activity, social capacity, and vigor. Outcomes included the self-reported type of outdoor footwear and clinical characteristics by sex were collected in 2019-2020.

SAMPLE

A total of 78 Roma participants self-identified as members of this ethnic minority and 72 participants non-Roma were assessed (n = 150).

RESULTS

The lower score values was recorded in the footwear and general foot health domains in Roma population. General population obtained higher scores in general health domains. The most common outdoor footwear types were running shoes and walking shoes in non-Roma population, versus flip flops and slippers in Roma population. Clinical characteristics did not show any statistically significant differences (p < .05).

CONCLUSION

Roma people wear flip flops and slippers and non-Roma people running shoes and walking shoes. These findings reveal cultural differences that make it easier for the Roma population to experience a greater burden of foot health problems. General foot health and foot pain dimensions show statistically significant differences among ethnicity.

Impact of quality of life related to foot problems: a case-control study

Foot problems are highly prevalent conditions, being a frequent reason for medical and podiatric consultation. The aim of this study was to compare the differences of quality of life (QoL) related to foot health in people with and without the presence of foot problems. A case–control study was carried out in an outpatient centre, where a clinician recorded data related to sociodemographic and clinical characteristics. In addition, self-reported data on foot health-related quality of life were recorded using the Spanish version of the Foot Health Status Questionnaire. The sample consisted of 498 participants (249 cases and 249 controls), with a median age of 30 years and an interquartile range of 23 years. The differences between the groups were statistically significant for gender, age, footwear, general health, foot health, and physical activity. Cases showed lower scores for the domain of footwear, physical activity and vitality compared to controls. Foot pathologies have a negative impact on quality of life related to foot health, and the domains of footwear, general health and physical activity seem to be the factors that are associated with the presence of alterations and foot deformities.

Manual Therapy Informed by the Fascial Distortion Model for Plantar Heel Pain: Results of a Single-Arm Prospective Effectiveness Study

Objectives: Plantar heel pain (PHP) is the most common cause of heel pain and can be debilitating; 20% of patients are refractory to standard of care. The Fascial Distortion Model (FDM), a novel manual diagnostic and treatment strategy, is purported to be effective for chronic pain; however, no rigorous studies document its effectiveness. We assessed the FDM for care of PHP. Design: Single arm prospective effectiveness study. Settings/Location: Outpatient primary care clinic; Fort Gordon, GA. Subjects: Outpatient adults. Interventions: Participants received an FDM-informed diagnostic and treatment strategy to identify fascial "distortions" at the foot based on patient-reported pain patterns and palpatory examination and then to provide distortion-specific manual therapy at baseline and 1 week. Outcome Measures: Primary outcome measure (0, 1, and 16 weeks): the Foot Pain subscale on the validated Foot Health Status Questionnaire (FHSQ; 0-100 points on each of eight separate subscales); secondary outcome measures (0, 1, and 16 weeks): the seven remaining subscales on the FHSQ, visual analog pain scale (VAS, 0-100 points), and plantar fascia thickness of the most effected foot assessed by ultrasound (0 and 16 weeks). Analysis was performed per protocol using repeated-measures analysis of variance. Results: One hundred and ninety-seven participants were screened; 33 were enrolled. Twenty-eight participants received two FDM procedures. Compared with baseline, improvement on the FHSQ Foot Pain (33.8-23.6 points) and Foot Function (23.9-19.8 points) subscales and VAS (44.7-27.7 points) at 16 weeks was statistically significant (all p's < 0.001) and clinically important representing large effect sizes. Relative to baseline, 16-week ultrasound demonstrated reduced average plantar fascia thickness (0.6-0.9 mm [p = 0.001]). Demographic characteristics were unrelated to response. Satisfaction was high. There were no serious adverse events; side effects included consistent mild-to-moderate self-limited pain. Conclusions: Participants with PHP who received FDM-informed care reported significant and sustained improvement on validated foot pain and foot function measures; additional findings included decreased plantar fascial thickness. These results require corroboration in a larger randomized controlled study. Clinical Trial Registration No: DDEAMC17005.

A Rasch analysis of the self-administered Foot Health Assessment Instrument (S-FHAI)

Background

Reliable and valid measurement is the foundation of evidence-based practice. The self-administered Foot Health Assessment Instrument (S-FHAI) was recently developed to measure patients’ evaluations of their own foot health. Evidence regarding the psychometric properties of the S-FHAI is limited. The aim of this study was to investigate those properties by using a Rasch analysis.

Methods

This methodological study analysed secondary data that was collected from nurses (n = 411) in 2015. The psychometric properties of the S-FHAI were evaluated using the Rasch model. Unidimensionality was analysed first, followed by item functioning, person misfit and differential item functioning (DIF).

Results

The S-FHAI demonstrated evidence of unidimensionality, with an acceptable item fit according to the Rasch model. Person fit and person separation were low, however, indicating restricted separation among different respondents. Item separation was high, demonstrating clear discrimination between the items. No DIF was detected in relation to gender, but significant DIF was demonstrated in relation to age for 6 of the 25 items.

Conclusions

The S-FHAI has potential for use in investigating self-reported foot health. The Rasch analysis revealed that the psychometric properties of the instrument were acceptable, although some issues should be addressed to improve the scale. In future, it may be beneficial to analyse the sensitivity of the items and to test the S-FHAI in more diverse patient populations.

Degree of Impact of Tailor's Bunion on Quality of Life: A Case-Control Study

Tailor’s bunion (TB) disease should be considered one of the foot injuries that causes disability in feet as well as general health. This case–control descriptive study investigated and contrasted the effects of different TB types in a sociodemographic population using the Foot Health Status Questionnaire (FHSQ). A sample of 100 subjects with a mean age of 51.70 ± 17.78 years was recruited and requested to reply to a foot health survey. Results were self-reported. Subjects were scored. Participants with TB type III (TB3) registered lower scores for foot pain, foot function, footwear, and foot health. Physical activity and social capacity had higher scores, and vigor and general health were lower. A Kruskal–Wallis test was used for systematic differences between the FHSQ and different TB types. In all analyses, statistical significance was considered a p-value <0.05 with a 95% confidence interval. Statistically significant differences were found between all domains of the FHSQ and TB, except for the social capacity domain and vigor. The FHSQ is an important measurement tool in TB subjects, showing that factors such as sex, age, and footwear used throughout an individual’s life are significantly associated with the development of TB3 and its influence on foot pain and foot health.

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.

Foot health-related quality of life in hemophiliacs: A case-control study

Background: Haemophilia is considered as a chronic genetic disease related with alteration in coagulation mechanism which affects to health related quality of life (HQoL). Purpose: The goal compared marks of HQoL, in haemophiliacs with respect non haemophilic subjects. Methods: A population of 74 subjects, were recruited from association of haemophilic illness separated in haemophilic subjects (n = 37) and no haemophilic (n = 37). For subjects who suffered haemophilia were enlisted from the association of haemophilic illness after a seminar of 45 minutes to them and to their relatives about foot health. Control subjects, were recruited from their relatives who live with the patient. The marks of the Foot Health Status Questionnaire Spanish S_FHSQ sub-scales were recompiled. Results: All S_FHSQ domains as foot pain, foot function, tootwear, general foot health, general health, physical activity and social capacity showed lower scores in the haemophilic than non-haemophilic group (P <0.01) except for vigour (P = 0.173). Regarding the rest sub-scale marks of S_FHSQ, showed no significant difference P <0.01. Conclusion: Subjects with a haemophilia showed significant worse foot QoL in all S_FHSQ domains except vigour domain compared with non-haemophilic subjects.
