Variations in the Thickness of the Plantar Fascia After Training Based in Training Race. A Pilot Study

Plantar fascia (PF) is a connective tissue made up of mostly type 1 collagen that is subjected to constant loads. This study evaluated the effect of continuous running on tissue stress in the PF by measuring changes in the thickness of the PF using ultrasound scans. It was a cross-sectional study involving 24 runners from the University of Valencia, recruited as volunteers between December 2018 and February 2019. A variety of data was recorded: (age, body mass index, type of footwear, number of workouts per week, KM run per week, sports injuries in the last year, pre and postrace ultrasound PF measurements). There were significant differences in the 3 postrace measurements of the left foot (<0.001). PF thicknesses were measured before and after running, with a minimal average difference of 0.4 mm in the medial and central fascicles, and 0.3 mm in the lateral fascicle. We observed PF thicknesses above 4mm in asymptomatic patients with no signs of vascularisation, proving that increased PF thickness is not the only criterion for diagnosis of plantar fasciitis.

How susceptible are our Achilles Tendons? Sonoanatomical assessment. A cross-sectional study

OBJECTIVE

the aim of this study is to observe whether there are ultrasound changes between men and women in the Achilles tendon at rest, at maximum passive force is applied and during walking.

MATERIAL AND METHODS

it was a cross-sectional study involving 27 healthy young participants recruited as volunteers between April to July 2022. A variety of data was recorded: (age, Body Mass Index, sex, smoking, current injury status, allergies, medications, previous surgeries, type of sport, and number of weekly workouts) and ultrasound measurements at rest and at passive force (Cross Sectional Area Achilles Tendon length, tendon thickness, Cross Sectional Area and pennation angle of the soleus muscle to the Achilles Tendon).

RESULTS

women demonstrated a statistically significant lower proximal and median thickness both at rest (4.5 vs 5.1 mm with p < 0.001 for proximal thickness; 4.4 vs 5.3 mm with p < 0.001 for median thickness) as well as during maximum eccentric contraction (4.3 vs 4.8 mm with p=<0.001 for proximal thickness; 4.1 vs 4.8 mm with p < 0.001 for median thickness).

CONCLUSION

there are significant sonoanatomical differences in vivo Achilles tendon between men and women.

Effects of Low-Dye Tape on Arch Height and Its Impact on the Medial Gastrocnemius Electromyographic Activity in Structurally Differentiable Foot Types: A Cross-Sectional Observational Study

BACKGROUND

Low-Dye tape (LDT) is a short-term treatment for plantar fasciitis, where external stabilization by means of the tape improves kinetics, kinematics, pain level, and electromyography (EMG).

PURPOSE

The purpose of this study was to compare the EMG of the medial gastrocnemius (MG) and changes in arch height (AH) based on the type of foot.

METHODS

A total of 30 subjects participated in this study; they walked on a treadmill barefoot and when taped, where the average activity and changes in AH were measured over a 30 s period. The statistical intraclass correlation coefficient (ICC) to test for reliability was calculated, and the Wilcoxon test was determined for measures of EMG and AH.

RESULTS

The reliability of the values of EMG was almost perfect. The data show that there was an increase in height in the comparison of the moment pre-baseline walking and post-taped walking on neutral feet (5.61 ± 0.46 vs. 5.77 ± 0.39 cm, p < 0.05), on pronated feet (5.67 ± 0.57 vs. 6.01 ± 0.53 cm, p < 0.001) and on supinated feet (5.97 ± 0.36 vs. 6.28 ± 0.27 cm, p < 0.05). In the MG, EMG activity decreased significantly in the taped condition compared to the baseline condition in neutral subjects (0.0081 ± 0.016 vs. 0.076 ± 0.016 mV, p < 0.05) and in pronated subjects (0.081 ± 0.022 vs. 0.068 ± 0.025 mV, p < 0.05).

CONCLUSIONS

It was demonstrated that with the use of LDT, there was an improvement in the average activity in the MG in pronated and neutral feet. All foot types improved in arch height with the use of tape.

Validation of Fixed Ultrasonography for Achilles Tendon Assessment: A Reliability Study

Background: It is important to highlight the advantages of ultrasound in assessing muscular and tendinous behavior due to its non-invasive nature and capacity for dynamic studies. However, evaluating tendons via ultrasound can be challenging given the complexity of anisotropic phenomena related to collagen fiber arrangement. This study aims to validate the reliability of fixed ultrasound compared to manual acquisition in measuring Achilles tendon thickness. Method: Twenty participants, six men and fourteen women, were recruited. Ultrasound was used to measure the Achilles tendon's thickness at two specific points (4 and 6 cm from the calcaneal insertion of the Achilles tendon). The measurements were conducted by two examiners, one with previous experience and another without. Results: The measurements at 6 cm from the calcaneal insertion showed α = 0.996, α = 0.998 for measurements at 4 cm using manual acquisition, and α = 0.997 for measurements with fixed ultrasound at rest. For the weight-bearing and ankle dorsiflexion measurements, the reliability was excellent (α = 0.999 and α = 1.000). Conclusions: The findings demonstrated excellent reliability in the ultrasound measurements of the Achilles tendon's thickness, even when performed by different evaluators and under load-bearing conditions. This study suggests the clinical utility of assessing anatomical structures under load, enhancing ultrasound's applicability beyond the examination table. It is concluded that fixed ultrasound acquisition exhibits excellent reliability in measuring the Achilles tendon's thickness, offering potential benefits for precise diagnosis of pathologies, planning surgical interventions, and reducing possible errors related to operator variability.

Effectiveness of hyaluronic acid in post-surgical cures following partial matricectomies with the phenol/alcohol technique: A randomized clinical trial

BACKGROUND

Post-operative cures with hyaluronic acid (HA) could potentially shorten the period recovery involved in the phenol technique for ingrown toenail. The aim of this study was therefore to compare a standard healing protocol with the experimental one based on hyaluronic acid cream.

MATERIAL AND METHODS

70 patients who had undergone phenol technique surgery for ingrown toenail were divided into two groups - control (n = 35) who received post-operative cures following the standard protocol with povidone iodine gel, and experimental (n = 35) who received cures with HA in the first 3 visits. Bleeding, total healing time, and perceived pain were assessed.

RESULTS

Patients in the control group recovered from the intervention in a total of 26.17 ± 7.75 days, while those in the HA group recovered in a significantly shorter time - 22.42 ± 2.41 days (p = 0.007, effect size 0.653). However, there were no between-group statistical differences in bleeding or perceived pain over the course of the post-surgery visits.

CONCLUSIONS

The use of low molecular weight hyaluronic acid is effective in reducing the phenol-technique healing time by 4 days compared with the standard cure. However, no extra effects such as reductions in bleeding or perceived pain can be expected in choosing this healing protocol.

Long COVID and Physical Therapy: A Systematic Review

Prolonged COVID is a persistent condition following the initial COVID-19 infection, which is characterized by a variety of symptoms that may include fatigue, muscle pain, sleep disturbances, "brain fog", respiratory, cardiovascular, digestive, neurological and dermatological symptoms. Physical therapy has been identified as a crucial aspect of the management of patients with long COVID, as it can help improve symptoms and overall physical function. The investigation of long COVID poses significant challenges due to the diversity and variability of symptoms, lack of clear diagnostic criteria, and limited understanding of the underlying mechanisms. The aim of this study is to conduct a systematic review of studies conducted in patients with long COVID in conjunction with interventions targeting respiratory function, particularly involving physical activity. To this end, we conducted a systematic review to analyze studies conducted on treatment programs for long COVID based on some form of physical activity. The protocol of the review was registered in the PROSPERO website, and the databases PubMed, Scopus, CINAHL and WOS were searched. Of the 62 initial articles, six were included in the review. The results obtained have positive implications for the advancement of physical activity as a therapeutic intervention for individuals with long COVID-19 and the conceptualization of evidence-based treatment protocols. Statistically significant results have been observed in studies of at least 6 weeks duration, in which inspiratory muscle training exercises are proposed. Further research is needed to better understand long COVID and develop effective treatment strategies.

Factors Influencing Adherence to Phototherapy in Patients With Psoriasis: A Cross-Sectional Study

AIMS

Assess the level of adherence to phototherapy and determine what factors influence it.

DESIGN

Cross-sectional.

METHODS

This study included a convenience sampling of 72 patients with psoriasis undergoing phototherapy. Data were collected through a self-reported questionnaire with sociodemographic variables, the Goldberg Anxiety and Depression Scale, the Short Form Health Survey and the Dermatology Life Quality Index. Adherence to the treatment and its ending was measured through a session record.

RESULTS

A small percentage of the participants demonstrated adequate adherence, and nearly half of them had low adherence. The factors statistically significant and with a negative impact on adherence were as follows: having a partner, experiencing anxiety or depression or using public transportation to get to the hospital. The probability of not adhering to the treatment increased when: patients found it difficult to attend therapy; perceiving their mental and physical health as being worse; experiencing anxiety or depression; having a diagnosed mental illness; being a man; or having had the sickness for an extended period of time.

CONCLUSION

This study determined the level of adherence to phototherapy and advanced our understanding of this variable. Women exhibited higher levels of adherence compared to men, although they reported worse perceived mental and physical health, and the disease had a higher impact on their life.

IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE

Informing phototherapy nurses on the factors that impact treatment adherence may help to increase the treatment compliance, which may improve psoriasis patients' clinical symptoms.

IMPACT

Increase the body of knowledge about the treatment that phototherapy nurses administer.

REPORTING METHOD

STORBE guidelines.

Follow-up of health-related quality of life and pain in a cohort of patients with rheumatoid arthritis before and after COVID-19

BACKGROUND

The foot is one of the anatomical structures of the body most affected in rheumatoid arthritis (RA), associated with the disability of patients, even more during COVID-19. The aim of this study was to analyse whether the period of physical inactivity during COVID-19 is an influential factor on health-related quality of life and foot pain in patients with RA.

METHODS

162 patients with foot pain and RA, recruited from the Hospital Virgen de las Nieves, Granada (Spain) were included. Data was collected during two different periods: January - December 2018 in person and June - September 2021 by phone. Patients were asked to complete the Spanish adapted version of the 12-Item Short Form Survey (SF-12) and the Visual Analogue Scale (VAS).

RESULTS

The results from the SF-12 questionnaires were divided between its two subscales (i.e., mental, and physical component). The physical component shows an improvement between 2018 and 2021, from 32.05 in 2018-35.18 in 2021 (p < 0.05). The opposite happened with the mental component, showing a deterioration, from 39.69 in 2018-34.48 in 2021 (p < 0.05). Regarding pain, VAS shows higher levels of pain with statistically significant differences, both in general pain (from 6 in 2018-7 in 2012) and in foot pain (from 5 to 7), (p < 0.05).

CONCLUSION

Mental quality of life and pain, both general and foot pain, are influenced by the period of physical inactivity during COVID-19.
