RESUMO

The Italian Selfcare diabetic foot questionnaire, (SDFQ-IT) is considered a diabetic foot self-care evaluation tool with 16 questions for assessing diabetic foot health disorders. To date, SDFQ has been validated in different languages, but an Italian version was lacking. Consequently, the purpose of this study was to translate and validate the Italian version of the SDFQ-IT (SDFQ-IT). A suitable method was developed for the translation protocol and cross-cultural validation from Spanish to Italian. Regarding the total marks from each sub-scale, agreement degrees, and confidence were analysed using the Cronbach's α and intraclass correlation coefficient (ICC), respectively. In addition, the mean ± SD differences between pre and post-tests were calculated and completed using the Bland and Altman distribution plots. Excellent agreement between the two versions based on Cronbach's α was demonstrated. Three sub-scales consisting of knowledge of foot hygiene, the appropriate use of footwear and socks, and podiatric self-care were added together to obtain the total score. Excellent retest reliability was shown for the total score. Test/retest reliability was excellent for the self-care domain, and shock and shoe sub-scales. There were no significant differences among any domain (P > .05). There were no statistically significant differences (P = .000) for the mean ± SDs differences between pre-and post-tests (92.9200 ± 12.914) [89.25-96.59] and 92.9200 ± 13.012 [89.22-96.62] points, respectively). Bland and Altman plots or clinically pertinent variations were not statistically significantly different. The SDFQ-IT is considered a strong and valid questionnaire with adequate repeatability in the Italian community.

RESUMO

BACKGROUND: Kinesiophobia can be an obstacle to physical and motor activity in patients with Parkinson's disease (PD). PD affects patients' independence in carrying out daily activities. It also impacts a patient's biopsychosocial well-being. The objective of this study was to analyze the levels and scores of kinesiophobia in PD patients and compare them with healthy volunteers. METHODS: We deployed a case-control study and recruited 124 subjects (mean age 69.18 ± 9.12). PD patients were recruited from a center of excellence for Parkinson's disease (cases n = 62). Control subjects were recruited from the same hospital (control n = 62). Kinesiophobia total scores and categories were self-reported using the Spanish version of the Tampa Scale of Kinesiophobia (TSK-11). RESULTS: Differences between cases and control groups were analyzed using the Mann-Whitney U test. Statistically significant differences (p < 0.05) were shown between groups when comparing kinesiophobia categories (or levels) and total scores, revealing higher kinesiophobia symptoms and levels in PD patients. All of the PD patients reported some degree of kinesiophobia (TSK-11 ≥ 18), while the majority of PD patients (77.3%) had kinesiophobia scores rated as moderate to severe (TSK-11 ≥ 25). On the other hand, ~45.1% of controls reported no or slight kinesiophobia and 53.2% reported moderate kinesiophobia. CONCLUSIONS: Total kinesiophobia scores were significantly higher in PD patients compared with healthy controls, with moderate to severe kinesiophobia levels prevailing in PD patients. Therefore, individuals living with PD should be evaluated and controlled in order to detect initial kinesiophobia symptoms.

RESUMO

Parkinson's disease is a common neurodegenerative disease and it is known to cause motor disturbances associated with musculoskeletal problems of the locomotor apparatus, and non-motor symptoms, that are believed to have a harmful effect on health, social functioning and mobility. The aim of this study was to evaluate depression in patients with Parkinson's Disease (PD) compared to subjects who do not have it. The sample consisted of 124 participants (mean age 69.18 ± 9.12). Patients with PD were recruited from a center of excellence for Parkinson's disease (cases n = 62) and healthy subjects without PD from their relatives and caregivers (control n = 62). The Spanish version of Beck's Depression Inventory (BDI) scores and categories were collected. A clear statistically significant difference (p < 0.05) was evident in the BDI scores between both groups. Parkinson's patients presented worse results on the BDI = 15.48 ± 7.24 points compared to healthy subjects with BDI = 7.03 ± 6.99 points. Regarding BDI categories, there were statistically significant differences (p < 0.001) for the greater BDI categories in the Parkinson's group compared with healthy subjects. The depression represents an important potential risk for increased symptoms and negative impact among patients with PD compared with healthy subjects.

RESUMO

BACKGROUND: The analysis of the center of pressure (COP) is a method used to assess the foot function, but its reliability and repeatability have not been evaluated. COP can be altered by diverse conditions, like an excessive foot pronation. Low-Dye taping is commonly used for the treatment of symptoms related to an excessive pronation. To date, no study has evaluated the effects of the Low-Dye taping on COP and the duration of its effects. Thus, the main purpose of this manuscript was to assess the reliability and repeatability of the percentage of center of pressure locus area (%CLA) in feet with an excessive pronation, and secondarily, to assess that the Low-Dye taping modifies the %CLA during the immediate 48 h. METHODS: An observational study of the reliability and repeatability of the %CLA variable with the Low-Dye taping in feet with excessive pronation was carried out. We used the EPS-Platform to evaluate the results of the variable in 6 conditions in a first session to evaluate the reliability of the results. We compared the results of the first session with the results in a second session to evaluate the repeatability of the results. We also carried out an ANOVA test to evaluate the changes that the taping produced in the variable between without taping with the rest of the 6 conditions. RESULTS: For the %CLA, we observed a reliability greater than 0.80, measured by the interclass ratio index, both in the first session before taping, and in the second session before taping, thus being a repeatability variable. In the following times, with taping, at 10 min with tape, at 20 min with tape, at 24 h with tape and at 48 h with tape; an interclass ratio coefficient (ICC) higher than 0.80 was again obtained, thus being a reliable variable in all measurements made. The Low-Dye taping did not change %CLA from the time the tape was put in until 48 h (p-value = 1.000). CONCLUSIONS: The %CLA variable, in feet with excessive pronation, proved to be a reliable variable in all the measurements obtained before putting on the tape and during the following 48 h with the tape, and a repeatable variable. The Low-Dye taping did not change the %CLA from the time the tape was put in until 48 h.

RESUMO

AIMS: To determine the fit factor and compliance with American Industrial Hygiene Association (AIHA) and Occupational Safety and Health Administration (OSHA) requirements of surgical masks and filtering respirators in male versus female nurses. DESIGN: A case-control gender study performed from 2016 to 2019. METHODS: A gender and age matched-paired sample of 74 nurses was recruited and divided into men (n = 37) and women (n = 37). FFP3 filtering respirators and surgical masks fit factors were compared between male and female nurses by Mann-Whitney U tests. These measurements were tested to pass or fail according to the OSHA (≥100) and AIHA (≥50) criteria by Fisher exact tests for a 95% confidence interval. RESULTS: Global fit factor mean (standard deviation) was 2.86 (2.73) and 3.55 (6.34) for male and female nurses wearing surgical masks (p = .180), respectively, and nobody passed neither OSHA nor AIHA criteria (p = 1.00). Nevertheless, global fit factor were 30.82 (28.42) and 49.65 (43.04) for male and female nurses wearing FFP3 respirators, respectively, being significantly lower and worse in male nurses (p = .037). According to OSHA criteria, only 2.70% and 13.51% of male and females nurses, respectively, passed with non-significant difference (p = .199), meanwhile 21.62% and 48.64% of male and female nurses, respectively, passed AIHA criteria showing significant differences (p = .027) wearing FFP3 respirators. CONCLUSIONS: All male and female nurses wearing surgical masks failed to pass OSHA and AIHA criteria. Global fit factor of the proposed FFP3 filtering respirators was decreased and worse in male than female nurses. IMPACT: Our recommendation is to avoid surgical masks use for protective purposes and use the proposed FFP3 filtering respirators among nurses. Each nurse should be fit tested for its own respirator with special caution in male nurses due to their lower fit factor achieved and most of them failed to pass OSHA and AIHA criteria, especially during COVID-19 pandemic.

RESUMO

While numerous studies and patient experiences have demonstrated the efficacy of spinal cord stimulation as a treatment for chronic neuropathic pain, the exact mechanism underlying this therapy is still uncertain. Recent studies highlighting the importance of microglial cells in chronic pain and characterizing microglial activation transcriptomes have created a focus on microglia in pain research. Our group has investigated the modulation of gene expression in neurons and glial cells after spinal cord stimulation (SCS), specifically focusing on transcriptomic changes induced by varying SCS stimulation parameters. Previous work showed that, in rodents subjected to the spared nerve injury (SNI) model of neuropathic pain, a differential target multiplexed programming (DTMP) approach provided significantly better relief of pain-like behavior compared to high rate (HRP) and low rate programming (LRP). While these studies demonstrated the importance of transcriptomic changes in SCS mechanism of action, they did not specifically address the role of SCS in microglial activation. The data presented herein utilizes microglia-specific activation transcriptomes to further understand how an SNI model of chronic pain and subsequent continuous SCS treatment with either DTMP, HRP, or LRP affects microglial activation. Genes for each activation transcriptome were identified within our dataset and gene expression levels were compared with that of healthy animals, naïve to injury and interventional procedures. Pearson correlations indicated that DTMP yields the highest significant correlations to expression levels found in the healthy animals across all microglial activation transcriptomes. In contrast, HRP or LRP yielded weak or very weak correlations for these transcriptomes. This work demonstrates that chronic pain and subsequent SCS treatments can modulate microglial activation transcriptomes, supporting previous research on microglia in chronic pain. Furthermore, this study provides evidence that DTMP is more effective than HRP and LRP at modulating microglial transcriptomes, offering potential insight into the therapeutic efficacy of DTMP.

RESUMO

Exercise intolerance may be considered a hallmark in patients who suffer from heart failure (HF) syndrome. Currently, there is enough scientific evidence regarding functional and structural deterioration of skeletal musculature in these patients. It is worth noting that muscle weakness appears first in the respiratory muscles and then in the musculature of the limbs, which may be considered one of the main causes of exercise intolerance. Functional deterioration and associated atrophy of these respiratory muscles are related to an increased muscle metaboreflex leading to sympathetic-adrenal system hyperactivity and increased pulmonary ventilation. This issue contributes to increased dyspnea and/or fatigue and decreased aerobic function. Consequently, respiratory muscle weakness produces exercise limitations in these patients. In the present review, the key role that respiratory muscle metaboloreceptors play in exercise intolerance is accurately addressed in patients who suffer from HF. In conclusion, currently available scientific evidence seems to affirm that excessive metaboreflex activity of respiratory musculature under HF is the main cause of exercise intolerance and sympathetic-adrenal system hyperactivity. Inspiratory muscle training seems to be a useful personalized medicine intervention to reduce respiratory muscle metaboreflex in order to increase patients' exercise tolerance under HF condition.

RESUMO

PURPOSE: The objective of this study is examine Quality of Life in subjects with chronic kidney disease utilizing Foot Health Status Questionnaire (FHSQ). MATERIAL AND METHODS: 101 subjects with chronic kidney disease (CKD) was studied in specialized clinics, in Extremadura (Spain). An observational descriptive study. The FHSQ was utilized to assess specific foot health (first section) and overall health (second division). The differences between clumps they were assessed using a t-test to independent samples. RESULTS: 59.40% (n = 60) were men and 40.59% (n = 41) women. The mean age was 68.77 ± 14.07. In first division of the FHSQ, a less score was registered in footwear domain (39.25) and in general foot health domain (46.37). In second division, less scores were resulted in general health domain (72) and vigour domain (60.43). CKD women got less scores in every domain. Women with CKD obtained significantly less scores in dimensions of foot pain, foot function, footwear, general foot health, general health and physical activity and there was no difference contrasted with men in the dimensions of social capacity and vigour. CONCLUSIONS: The studied CKD population has problems their feet. Quality of life of CKD subjects is negatively impacted by health of their feet, difficulties with footwear, their overall health, and lack of vitality. Women with CKD show lower values of quality of life contrasted to male patients, associated with inability to perform physical activity, lack of energy and tiredness.

RESUMO

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.

RESUMO

Purpose The association between voice alterations, health-related quality of life (HRQL), and chronic respiratory diseases, such as asthma and chronic obstructive pulmonary disease (COPD), has previously been reported. The aim of this study was to test the hypothesis that HRQL and dysphonia-associated handicap of patients diagnosed with asthma or COPD are worse than healthy controls. Method A case-control study in which participants were recruited by a consecutive sampling method from a single institution was conducted. Three groups were created: (a) asthma (51 patients), (b) COPD (52 patients), and (c) 50 healthy controls. Self-reported handicap associated with dysphonia was assessed using the 30-item Voice Handicap Index (VHI-30); meanwhile, HRQL was tested via the European Quality of Life (EQ) Questionnaire and the EQ-visual analog scale. Also, aerodynamic assessment applied to phonation was assessed, and maximum phonation time and s/e index were registered. Results VHI scores were higher for asthma and COPD (7.19 ± 8.31 and 11.80 ± 15.18, respectively) than in the control group (3.72 ± 6.78). The EQ index was lower in asthma and COPD patients than in controls. The EQ-visual analog scale showed lower scores in asthma and COPD than in the controls. Conclusions HRQL was worse in COPD patients than in asthma patients. Even though the patient groups showed worse VHI and HRQL scores than the healthy controls, the scores fell within the normal variation range. No significant variations in the maximum phonation time index between groups were noted.

RESUMO

BACKGROUND: The effects of the dry needling technique and pain reduction have been demonstrated in numerous quality studies. However, the mechanical effects of dry needling are largely unknown. METHODS: A total of 18 subjects with flexor digitorum brevis muscle myofascial trigger point were evaluated pre- and post-deep dry needling. We measured static footprint variables in a pre-post study. MAIN FINDINGS: We found differences in rearfoot maximum pressure (119.22-111.63 KPa; p = 0.025), midfoot maximum pressure (13.68-17.26 KPa; p = 0.077), midfoot medium pressure (4.75-6.24 KPa; p = 0.035) and forefoot surface (86.58-81.75 cm2; p = 0.020). All variables with significant differences decrease, with the exception of forefoot surface which showed an increase. CONCLUSIONS: After flexor digitorum brevis muscle dry needling, midfoot plantar pressures (maximum and medium) and forefoot surface were increased, and rearfoot maximum pressure was decreased.

RESUMO

Background: Parkinson's disease (PD) is a common and complex neurological problem. Gait abnormalities are frequent in PD patients, and this increases the risk of falls. However, little is known about foot deformities and footwear in this vulnerable population. Here we investigate whether patients with PD use an appropriate shoe size and know if they have foot deformities or alterations. Methodology: A study of a series of observational descriptive cases in a convenience sample (n = 53 patients) diagnosed with Parkinson's disease. One trained investigator evaluated foot and ankle health. The footwear and foot measurements were obtained using a Brannock device. Results: The podiatric examination and footwear examination detected a high presence of podiatric pathologies and inappropriate footwear. This has a negative impact on the quality of life of these patients. Conclusions: This research detected an elevated number of people with foot deformities or alterations. Moreover, a high proportion of participants with PD wear inadequate footwear (in length, width, or both).

RESUMO

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.

RESUMO

BACKGROUND: A literature review did not reveal any studies concerning the intramedullary transfer of the flexor digitorum brevis tendons (FDB) technique with a single longitudinal incision through the proximal phalanx of the toes. The main goal of this investigation was to demonstrate whether the FDB tendons of the toes are long enough to enable intramedullary transfer to the dorsal area of the proximal phalanx. METHODS: We examined whether the technique would allow the surgeon to transfer the FDB tendons through the proximal phalanx of the toes. The technique transfers the FDB tendons through the proximal phalanx dorsal area of the toes using an intramedullary transfer of the FDB tendons. The intramedullary transfer of the FDB tendons was performed through a single dorsal incision. RESULTS: The FDB tendons for the second, third, and fourth toes were performed in 100% of the feet. No ruptures in any toe in which the surgical technique was performed was noted, and no proximal phalanges of the second, third, and fourth toes were fractured. CONCLUSIONS: Transfer of FDB tendons via the intramedullary approach of the proximal phalanx of the second, third, and fourth toes is possible. The FDB tendons have sufficient length for transfer via an intramedullary transfer and were carried out in 100% of the second toes. For a successful transfer, it is essential to perform a thorough resection of the extensor digitorum longus aponeurosis since it has expansions intimately attached to the plantar base of the proximal phalanx of the toe.

RESUMO

Background: Usually, physicians use filtering respirators in clinical settings to a lesser extent than other simpler surgical masks. The study aim was to determine the fit factor of surgical and other types masks commonly used in clinical settings compared with FFP3 filtering respirators. Materials and Methods: A cross-sectional study was carried out recruiting a total sample of 78 physicians. Fit factor was measured to determine particles count into masks compared to particles count outside of the masks meanwhile physicians carried out a protocol composed by 8 exercises as well as the global fit factor total scores. First, fit factor was analyzed with the usual surgical masks used by physicians in clinical settings. Second, fit factor was determined with the proposed FFP3 filtering respirators. Results: Most participants (97%) used surgical masks. Statistically significant differences (P<0.001) with an effect size from moderate to large (d=0.61-1.00) were shown for fit factors in the different exercises and total scores between surgical and other masks (3.2±5.0) and FFP3 filtering respirators (40.7±37.8). Generally, FFP3 filtering respirators showed a higher fit factor in the different exercises and total scores compared to the commonly used surgical and other types masks in clinical settings. Conclusions: Despite most physicians used surgical masks in clinical settings, filtering FFP3 masks showed a higher fit factor in the different exercises and total scores compared with the used surgical masks and filtering respirators such as FFP1, FFP2 and other types in clinical settings.

RESUMO

Aim: It is argued that chronic pain patients who reduce/eliminate their opioids may have compromised pain relief. This study therefore aimed to analyze if reduced opioid consumption associated with 10-kHz spinal cord stimulation adversely affected pain relief. Methods: Post hoc analysis was performed on data from two prospective studies in subjects with upper limbs and neck pain conducted in USA. Results & conclusion: A 10-kHz spinal cord stimulation treatment was associated with reduction in mean visual analog scale scores for upper limbs and neck pain and mean daily opioid consumption. Pain scores decreased in subjects who decreased opioid use and in those who maintained/increased use. Opioid reduction and pain relief was also achieved in subjects taking >90 mg morphine equivalents of opioids at baseline.

RESUMO

Background: The triceps surae muscle has been identified with propulsion during running gait, and typical heel-lift orthotics (THOs) have been used to treat some sports injuries of this structural-biomechanical unit. The effects of a novel propulsion heel-lift orthotic (PHO) on surface electromyography (EMG) activity of the gastrocnemius during a full cycle of running have yet to be tested. Purpose/Hypothesis: We aimed to assess EMG changes in gastrocnemius medialis and lateralis muscle activity when wearing THOs, PHOs, or neutral sports shoes only (SO) during running. We hypothesized that EMG activity of the triceps surae muscle would be lower for PHOs than THOs or SO during running. Study Design: Controlled laboratory study. Methods: A total of 26 healthy, regular recreational runners of both sexes (mean age, 33.58 ± 6.02 years) with a neutral Foot Posture Index and rearfoot strike pattern were recruited to run on a treadmill at 9 km/h using aleatory THOs of 6 and 9 mm, PHOs, and SO while EMG activity of the gastrocnemius medialis and lateralis muscles was recorded over a 30-second period. Intraclass correlation coefficients were calculated to assess reliability. Results: The intraclass correlation coefficient values indicated near perfect reliability, ranging from 0.801 for 6-mm THOs to 0.959 for SO in the gastrocnemius lateralis muscle. EMG activity of the gastrocnemius lateralis muscle was greater for PHOs (25.516 ± 4.780 mV) than for SO (23.140 ± 4.150 mV) (P < .05), but EMG activity of the gastrocnemius medialis muscle did not show any statistically significant difference between conditions (23.130 ± 2.980 mV vs 26.315 ± 2.930 mV, respectively) (P = .3). Conclusion: A novel PHO may increase muscle activity of the gastrocnemius lateralis during a full cycle of running gait; consequently, its prescription to treat triceps surae muscle injuries is cautioned. Clinical Relevance: The prescription of novel PHOs could increase EMG activity, which has not been previously described.

RESUMO

San-Antolín, M, Rodríguez-Sanz, D, Becerro-de-Bengoa-Vallejo, R, Losa-Iglesias, ME, Martínez-Jiménez, EM, López-López, D, and Calvo-Lobo, C. Neuroticism traits and anxiety symptoms are exhibited in athletes with chronic gastrocnemius myofascial pain syndrome. J Strength Cond Res 34(12): 3377-3385, 2020-Common psychological factors, such as anxiety or neurotic personality traits, seem to be associated with pain suffered by athletes. Gastrocnemius muscles present a high prevalence for injury in athletes. These muscles are a region in which myofascial pain syndrome (MPS) frequently develops. Myofascial pain syndrome is characterized by the presence of active myofascial trigger points (MTrPs). This study compared different personality and anxiety symptoms between athletes with and without active MTrPs in the gastrocnemius. A case-control study was conducted in an outpatient clinic. Athletes who performed moderate or vigorous physical activity according to the International Physical Activity Questionnaire were included. Fifty paired-matched athletes with and without active MTrPs in their gastrocnemius muscles (n = 25 in each group) were recruited. Different personality traits (neuroticism, extraversion, psychoticism, and sincerity) and anxiety (state and trait) were evaluated by the Eysenck Personality Questionnaire and State-Trait Anxiety Inventory, respectively. Statistically significant differences (p < 0.01) with an effect size from moderate to large (d = 0.75-1.29) were found for greater neuroticism and sincerity traits in addition to state and trait anxiety in athletes with gastrocnemius MPS compared with healthy controls. In conclusion, athletes with gastrocnemius active MTrPs exhibited higher neuroticism and anxiety symptoms compared with healthy athletes. Mental health may play a key role in athletes with myofascial pain, and future studies should be performed to determine whether neuroticism-related and anxiety-related psychological care could be a key intervention in athletes with gastrocnemius active MTrPs to improve athletic performance and rehabilitation or prevent injuries.
