Ultrasonography Comparison of Pelvic Floor and Abdominal Wall Muscles in Women with and without Dyspareunia: A Cross-Sectional Study

[Abstract] Pelvic floor hypertonicity and narrowing of the levator ani hiatus is traditionally assumed in women with dyspareunia and considered a therapeutical target by physical therapists. However, accurate pre-treatment assessment of pelvic floor muscles is difficult to perform in clinical sites. In addition, the abdominal musculature has not been evaluated in this population, despite its relationship with pelvic floor disfunctions. The purpose of this study was to determine the existence of differences in the length of the anteroposterior diameter of the levator ani hiatus (APDH), the thickness of the abdominal wall musculature and the interrecti distance (IRD) in subjects with dyspareunia compared to a control group. A cross-sectional observational study was designed using ultrasound imaging to measure the APH, the thickness of the abdominal musculature—rectus abdominis (RA), transverse abdominis (TrAb), internal oblique (IO), external oblique (EO)—and IRD at rest and during contraction. Thirty-two women were recruited through advertising and social webs and divided into two groups: dyspareunia (n = 16) and no dyspareunia (n = 16). There were no statistically significant differences (p < 0.05) in RA, TrAb, OI and OE muscle thickness. No differences in APH or in supraumbilical and infraumbilical IRD were found. The findings of this study suggest that the relationship between the abdominal structure/levator ani hypertonia and dyspareunia remains uncertain

Ultrasound-Guided Percutaneous Neuromodulation in Patients with Chronic Lateral Epicondylalgia : A Pilot Randomized Clinical Trial

Objective: The aim was to analyze effects of a percutaneous neuromodulation (PNM) treatment on the radial nerve, regarding pain, functionality, electrophysiologic excitability, and morphology, in patients with chronic lateral epicondylalgia (LE). Methods: Twenty-four patients with chronic unilateral elbow pain were recruited for this preliminary study and were divided into two groups: control (n = 12) and PNM group (n = 12). The subjects in the PNM group received percutaneous peripheral neurostimulation with an acupuncture needle that was located next to the nerve with ultrasound guidance. Pain using a numerical rating scale (NRS), functional ability using patient-rated tennis elbow evaluation (PRTEE), radial nerve cross-sectional area measured by ultrasound, and chronaxie and accommodation index (AI) measured by the strength-duration curve were evaluated. Results: Both groups showed no differences in the baseline measurements (all p = 0.001). However, at the end of the treatment, there were significant differences between groups since only the PNM group significantly improved their values compared to their baseline values: level of pain and cross-sectional area (CSA) values showed a significant decrease while the PRTEE scores showed a significant improvement. Then, regarding AI, the PNM group showed significant improvement for the electrophysiologic nerve excitability pattern, reporting normal function in all radial nerves after treatment (p = 0.001). However, chronaxie values always reported similar values with no differences between groups (p >0.05); Conclusion: Ultrasound-PNM technique may be an interesting therapeutic tool for the treatment of chronic LE due to the improvement in the level of pain, functionality, nerve morphology, and excitability in this population

Comparison of the Abdominal Wall Muscle Thickness in Female Rugby Players Versus Non-Athletic Women: A Cross-Sectional Study

Background and Objectives: Rugby players engage in demanding, high loading muscular activity in the spine. Study of the abdominal wall architecture in female rugby athletes is relevant to the possible muscular asymmetry secondary to sport practice and the relationship between the abdominal wall and the pelvic floor muscles. Activation of the transversus abdominis (TrAb) generates an increase in the bladder neck muscle. Moreover, an increased interrecti distance (IRD) is related to urinary incontinence and has a higher prevalence in athletic women. The aim of the present study was to compare and quantify, with ultrasound imaging (USI), the thickness of the transversus abdominis (TrAb), external oblique (EO), internal oblique (IO), rectus abdominis (RA), and interrecti distance (IRD) in female rugby players versus non-athletic women in order to improve upon existing knowledge about abdominal wall configuration in female athletes. Materials and Methods: A sample of 32 women was recruited at the Universidad Europea Research Lab and divided in two groups: a rugby group (n = 16) and a non-athletic women group (n = 16). The thickness of the TrAb, EO, IO, RA, and IRD were assessed by USI in both groups. Results: There were statistically significant differences for the ultrasound evaluation thickness of the right TrAb (p = 0.011; d = 0.10), EO (p = 0.045; d = 0.74), IO (p = 0.003; d = 1.32), and RA (p = 0.001; d = 1.38) showing a thickness increase for the rugby group with respect to the control group. For the IRD thickness, there were no significant differences (p > 0.05) between groups. Conclusions: An increased TrAb, IO, EO, and RA thickness may be shown in female rugby players versus non-athletic women. Nevertheless, statistically relevant differences were not found for the IRD between both groups

Impact of eSports semiprofessional practice on the trunk stabilizer muscle complex. A cross-sectional study

Introduction: ESports have emerged in the sporting paradigm achieving a great deal of importance both in terms of audience and economics. Professional players have to improve their performance through training, which leads to an increase in the risk of injuries derived from long periods of time spent a sitting position, sedentarism and repetitive movements. The most prevalent injury is low back pain (LBP), probably due to the professionals’ lifestyles, similar to the day-to-day activity of office workers but acquired at a younger age. Objective: The aim of this study was to assess the morphology of the trunk stabilizing muscles in semiprofessional eSport players in comparison with healthy subjects, using ultrasonography. Methods: A total of 20 participants were recruited (10 players from a semiprofessional eSports team and 10 age-matched healthy controls). Ultrasound measurements of the thickness of the transversus abdomini (TrAb), internal oblique (IO), external oblique (EO), rectus abdomini (RA) and lumbar multifidus (LMult) muscles, and interrecti distance (IRD) were recorded. Results: Statistically significant differences were found with decreased thickness in the eSports group bilaterally in TrAb (p < 0.01) and IO (p < 0.05), right EO (p < 0.05) and right RA (p < 0.01); and decreased IRD (p < 0.01). Conclusions: Statistically significant differences were found between young semiprofessional eSports players and healthy adults in this study, with morphologic characteristics similar to those found in older adults with chronic LB

Heart Rate Variability monitoring during Interferential Current application in the lower back area : a cross-sectional study

[Abstract] Vasovagal reactions may occur occasionally during electrical stimulation using interferential current (IFC). The purpose of this study was to examine variations in autonomic activity during the application of IFC in asymptomatic participants by analysis of their heart rate variability (HRV). Seventy-three male volunteers were randomly assigned to a placebo group (n = 36; HRV was documented for 10 min, both at rest and during a placebo intervention) and an intervention group (n = 37; HRV was documented for 10 min in two conditions labelled as (1) rest and (2) application of IFC technique on the lumbar segment). The diameters of the Poincaré plot (SD1, SD2), stress score (SS), and the ratio between sympathetic and parasympathetic activity (S/PS) were measured. After interventions, differences amongst the placebo group and the IFC group were found in SD2 (p < 0.001), SS (p = 0.01) and S/PS ratio (p = 0.003). The IFC technique was associated with increased parasympathetic modulation, which could induce a vasovagal reaction. Monitorization of adverse reactions should be implemented during the application of IFC technique. HRV indicators might have a part in prevention of vasovagal reactions. Further studies in patients with lumbar pain are needed to explore possible differences in HRV responses due to the presence of chronic pai

Comparison of Lateral Abdominal Musculature Activation During Expiration With an Expiratory Flow Control Device Versus the Abdominal Drawing-in Maneuver in Healthy Women : A Cross-Sectional Observational Pilot Study

The purpose of the present study was to quantify and compare lateral abdominal musculature thickness, including the transverse abdominis (TrA), internal oblique (IO), and external oblique (EO) muscles, via rehabilitative ultrasound imaging (RUSI) during the use of the expiratory flow control device (EFCD) versus the classic abdominal drawing-in maneuver (ADIM). Materials and Methods: A cross-sectional observational pilot study. Twenty-one women were recruited and assessed the thickness of each muscle (TrA, IO, and EO) by ultrasound imaging at rest, during the ADIM, and during expiration with the EFCD. Waist circumference was also measured under the same circumstances. Results: Statistically significant differences were observed between ADIM, EFCD, and at rest condition for the thickness of the TrA (p = 0.001) and IO (p = 0.039). Moreover, statistically significant differences for TrAb at rest compared with the ADIM (p = 0.001, Cohen's d = 2.183) and at rest and with the EFCD (p = 0.001, Cohen's d = 2.843). In addition, between ADIM and EFCD were not statistically significant, although a moderate effect size was found (p = 0.055, Cohen's d = 0.694). For the IO muscle thickness, significant differences were reported between the EFCD and at rest (p = 0.038), Cohen's d = 0.081). Conclusions: Significant differences in the increase of the thickness of the TrA and IO muscles during the use of the EFCD and the ADIM with respect to rest. In addition, for the TrA, statistically significant differences were found during expiration with the EFCD with respect to the ADIM. Expiration with EFCD can be a useful method for the activation of the TrA

Current understanding of the diagnosis and management of the tendinopathy: An update from the lab to the clinical practice

[Abstract] Tendinopathy is labeled by many authors as a troublesome, common pathology, present in up to 30% medical care con- sultations involving musculoskeletal conditions. Despite the lasting interest for addressing tendon pathology, current re- searchers agree that even the exact definition of the term tendinopathy is unclear. Tendinopathy is currently diagnosed as a clinical hypothesis based on the patient symptoms and physical context. One of the main goals of current clinical management is to personalize treatment approaches to adapt them to the many different needs of the population. Tendons are complex structures that unite muscles and bones with two main objectives: to transmit forces and stor- age and release energy. Regarding the tensile properties of the tendons, several authors argued that tendons have higher tensile strength compared with muscles, however, are con- sidered less flexible. Tendinopathy is an accepted term which is used to indicated a variety of tissue conditions that appear in injured tendons and describes a non-rupture damage in the tendon or para- tendon, which is intensified with mechanical loading Even when the pathoetiology of tendinopathy is unclear, there is a wide array of treatments available to treat and manage tendinopathy. Although tendinitis usually debuts with an in- flammatory response, the majority of chronic tendinopathies do not present inflammation and so the choosing of treat- ment should vary depending on severity, compliance, pain and duration of symptoms. The purpose of this article is to review and provide an overview about the currently research of the tendon diagno- sis, management and etiology

Does function determine the structure? Changes in flexor hallucis longus muscle and associated performance related to dance modality: A cross-sectional study

Background and Objectives: Flexor hallucis longus pathology is one of the most common conditions of the ankle and foot in dancers, due to the high demand of dance movements performed in an extreme plantar flexion and dorsiflexion range of motion. The objectives of this study were to determine the bilateral differences between the thickness and cross-sectional area of the flexor hallucis longus muscle in dancers, to establish possible differences between dance modalities, and to analyze whether there is a correlation between ultrasonographic parameters or performance variables and the dance modality. Material and Methods: A sample of 50 (29 classical and 21 contemporary) full-time pre-professional female dancers were included in the study. The thickness and cross-sectional area of the flexor hallucis longus muscle were evaluated for both limbs using ultrasound imaging. The range of movement of the first metatarsophalangeal joint was measured using functional extension with maximal ankle plantarflexion, balance was measured in a unilateral stance with the heel raised, endurance was evaluated through a modified heel rise fatigue test, and a counter movement jump to assess the vertical jump performance was measured bilaterally. Results: There were no significant differences recorded between the dominant and non-dominant limbs for each variable, within both groups. Contemporary dancers showed a greater thickness and cross-sectional area of the flexor hallucis longus muscle than classical dancers. However, classical dancers showed an increase of balance, endurance, range of movement of the first metatarsophalangeal joint, and counter movement jump with respect to contemporary dancers. Conclusion: Bilateral symmetry was identified in all variables for both groups. The size and performance of the flexor hallucis longus muscle may be influenced by the specific nature of dance modalit

Dinamic Balance Performance in ralation to the dependence in Activities of Daily Living: A cross sectional study in stroke

Aim: to determine if dynamic balance is related to activities of daily living (ADL) dependence in stroke patients. Methods: a cross-sectional study was carried out. The Barthel index (BI) was used to assess ADL dependence. The Timed Up and Go Test (TUG) and the Four Square Step Test (FSST) were used to evaluate dynamic balance. A Spearman correlation was used assuming a data abnormality in the performance of TUG and FSST and considering a significance of p<0.05. Results: 62 stroke patients were evaluated. The BI showed correlations with the performance of the TUG and the FSST. These correlations were also found between performance of both balance tests and ADLs, such as bathing, moving, and going up and down stairs. In contrast to TUG, correlations were estimated between the ADL related to dressing and the performance of the FSST. Conclusion: dynamic balance evaluated by the TUG and the FSST showed correlations with the ADL dependency in stroke patients.Sin financiaciónNo data 2020UE

The efficacy of physical therapy on the improvement of the motor components of visual attention in children with cerebral palsy: A case series study

This paper has attempted to compare the effects of Bobath’s concept with control’s session on the improvement of visual attention in children with cerebral palsy. A 10 children sample (7 girls and 3 boys) aged 6 to 16 years (median, 12 years) was collected. The group who had received Bobath-based treatment crossed-over to control treatment and the previous control group received Bobath-based treatment for once a week. Measures were assessed at pre- and posttreatment. Outcome measure included the visual attention, we used Conners’ Kiddie Continuous Performance Test (K-CPT). Bobath’s session targeted to crossed-over participants produced greater improvements in K-CPT(RT) (difference=33.1, P<0.05) at posttreatment compared to the control’s session group, whereas the improvement of K-CPT did not differ between groups. The results of this case series study showed a significant improvement on visual attention through the improvement of motor control functions after the Bobath’s session over the control’s session.Sin financiaciónNo data JCR 20190.422 SJR (2019) Q2, 96/207 Physical Therapy, Sports Therapy and Rehabilitation; Q3, 157/284 Orthopedics and Sports MedicineNo data IDR 2019UE
