Ultrasonography features of abdominal perimuscular connective tissue in elite and amateur basketball players: an observational study.

The purpose of this study was to assess and compare with rehabilitative ultrasound imaging (RUSI) the perimuscular connective tissue (PMCT) and interrecti distance (IRD) between elite and amateur basketball players. A sample of 22 healthy basketball players was included and divided into two groups: elite basketball players from Spanish 1st division (n = 11) and amateur basketball players from an entertainment Spanish division (n = 11). Ultrasound images of the external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), rectus anterior (RA) and IRD PMCT were measured and analysed by the ImageJ software. Measurements of abdominal wall muscles PMCT present statistically differences (P < .05) for an increase of perimuscular connective tissue of external oblique (PMCTEO), perimuscular connective tissue of transversus abdominis (PMCTTA) of the left side and an increase of PMCTEO on the right side in favor of the elite group. Rather, the study showed statistically differences (P < .05) for a decrease of perimuscular connective tissue between the internal oblique and transversus abdominis (PMCTIO-TA), and a decrease in PMCT total summation of the left side with elite group in respect to amateur group. This study reported an increase of left PMCTEO, left PMCTTAA, right PMCTEO as well as a decrease of left PMCTIO-TA and in PMCT total summation on the left side.

Effectiveness of surgical hand antisepsis using chlorhexidine digluconate and parachlorometaxylenol hand scrub: Cross-over trial.

BACKGROUND: Chlorhexidine and parachlorometaxylenol (PCMX) are antiseptics recommended for surgical hand antisepsis. To our knowledge, PCMX has not been evaluated for bactericidal efficacy "in vivo. METHODS: We conducted a randomized, double-blind, controlled crossover trial to compare the bacterial loads on fingertips and fingernails under laboratory conditions after use of antiseptic test products, including chlorhexidine digluconate 4%, PCMX 3%, and a reference solution of propan-1-ol 60% (P-1). We assessed bacterial load after a prewash with soft soap, immediately after application of an antiseptic, and 3 hours after application and wearing of sterile, powder-free gloves. Our procedures followed those specified by European Norm (EN) 12791 for evaluating surgical hand antiseptics and using cotton swab for fingertips and fingernails. RESULTS: Chlorhexidine digluconate 4% and PCMX 3% did not decrease bacterial load on the hands. The bactericidal performances of chlorhexidine digluconate 4% and PCMX 3% did not differ significantly. Chlorhexidine digluconate 4% and PCMX 3% increased bacterial load on the fingertips after participants had worn gloves for 3 hours. Fingernails had greater bacterial loads than skin on the fingertips. CONCLUSIONS: Chlorhexidine digluconate 4% and PCMX 3% had similar bactericidal efficacy, but they failed to meet the EN 12791 efficacy standard. Fingernails should be a particular focus of antisepsis in preparation for surgery.The trial was registered at ClinicalTrials.gov (ID: NCT02500758).

Effectiveness of median nerve neural mobilization versus oral ibuprofen treatment in subjects who suffer from cervicobrachial pain: a randomized clinical trial.

INTRODUCTION: Oral ibuprofen (OI) and median nerve neural mobilization (MNNM) are first line treatments for patients who suffer cervicobrachial pain (CP). OI may produce side effects which are not tolerated by all subjects who suffer CP, whereas MNNM has no known side effects. Therefore, the aim of this study was to assess the effectiveness of both treatments (OI vs. MNNM) in CP. MATERIAL AND METHODS: This investigation was a blinded parallel randomized clinical trial (NCT02593721). Sixty-two participants diagnosed with CP were recruited and randomly assigned to 2 groups (n = 31), which received MNNM or 1200 mg/day OI treatment for 6 weeks. The numeric rating scale for pain intensity was the primary outcome. The cervical rotation range of motion (CROM) and the upper limb function were the secondary outcomes. RESULTS: The results showed that OI treatment (η2 = 0.612-0.755) was clearly superior to MNNM (η2 = 0.816-0.821) in all assessments (p < 0.05) except for the CROM device results, which were equivalent to those of the MNNM group (p > 0.05). Three subjects were discharged because of OI side effects. CONCLUSIONS: Oral ibuprofen may be superior to MNNM for pain reduction and upper limb function increase of subjects with CP. Nevertheless, both treatments were effective. Median nerve neural mobilization may be considered an effective non-pharmaceutical treatment option in subjects with CP. Regarding OI adverse effects, our findings challenge the role of pharmacologic versus manual therapy as possible treatments that may improve pain intensity and upper limb functionality in subjects with CP.

Ultrasound evaluation of intrinsic plantar muscles and fascia in hallux valgus: A case-control study.

A cross-sectional area (CSA) and thickness reduction of the abductor hallucis (AbH) is shown in subjects with hallux valgus (HV). To date, other soft-tissue structures have not been researched in relation with HV. The aim of this study was to compare the CSA and thickness of the intrinsic plantar muscles and fascia (PF) between feet with and without HV. Therefore, a cross-sectional and case-control study was performed using B-mode with an iU22 Philips ultrasound system and a 5 to 17-MHz transducer. The CSA and thickness were measured for the AbH, flexor digitorum brevis (FDB) and flexor hallucis brevis (FHB), and also the thickness for the anterior, middle, and posterior PF portions. A convenience sample of 40 feet, 20 with HV and 20 without HV, was recruited from a clinical and research center. A multivariate regression analysis using linear regression was performed to evaluate the ultrasound imaging measurements (α = 0.05). Consequently, statistically significant differences were observed between the groups (P < 0.05) for the AbH and FHB thickness, and CSA reduction, and also the plantar fascia thickness increase in favor of the HV group. On the contrary, the FDB thickness and CSA did not show statistically significant differences (P ≥ 0.05). In conclusion, the CSA and thickness of the AbH and FHB intrinsic plantar muscles are reduced, whereas the thickness of the anterior, middle, and posterior PF portions are increased, in subjects with HV compared with those without HV.

Interrater Reliability in the Clinical Evaluation of Myofascial Trigger Points in Three Ankle Muscles.

OBJECTIVE: The purpose of this study was to evaluate interrater reliability in the diagnosis of myofascial trigger points (MTrPs) in the tibialis anterior, peroneus brevis, and extensor digitorum longus muscles. METHODS: A reliability research study was performed. Three physical therapists with clinical experience in myofascial pain functioned as raters and randomly and bilaterally evaluated the ankles of 40 subjects in the Madrid public health care system. The absence or presence of MTrPs, nodules in taut bands, patterns of referred pain, local twitch response (LTR), and jump-sign were evaluated. RESULTS: We calculated the pairwise interrater agreement and κ-value concordance of the presence or absence of trigger points (55%-85%; κ = 0.12-0.60), palpable nodules in taut bands (63%-90%; κ = 0.24-0.60), referred pain (63%-85%; κ = 0.20-0.54), and jump sign (62%-89%; κ = 0.15-0.72) in the 3 studied muscles. The LTR could only be evaluated in the tibialis anterior (43%-70%; κ = 0.05-0.21), and evaluation was not possible for the other muscles. CONCLUSIONS: Three blinded raters were able to reach acceptable pairwise interrater agreement (percentage of agreement value ≥70%) for the presence or absence of MTrPs and LTR in the tibialis anterior, as well as for nodules in taut bands, referred pain, and the jump sign for the extensor digitorum longus. The peroneus brevis showed a wide percentage of agreement value, ranging from 31% to 82%. The results of this study showed that expert raters can agree, with slight-to-moderate concordance, with regard to the clinical testing of muscle trigger points by direct palpation of the 3 muscles studied: the tibialis anterior, the extensor digitorum longus, and the peroneus brevis. Interrater reliability seems to be muscle dependent, especially with regard to the depth of the muscle.

Gift-Giving in the Podiatric Medical Student-Patient Relationship.

We sought to explore the relationship between the podiatric medical student and the patient as it relates to the act of gift-giving as a sign of gratefulness for the services provided. This article presents the clinical case of a man who visited a podiatric medical student because of pain in his feet and subsequently presented the student with several gifts. Philanthropy, empathy, a positive attitude, treatment instructions, and the time devoted to the patient are some of the reasons why patients offer gifts to podiatric medical students. The relationship between the podiatric medical student and the patient and the act of gift-giving by patients are of ethical concern.

Ultrasonography Comparison of Peroneus Muscle Cross-sectional Area in Subjects With or Without Lateral Ankle Sprains.

OBJECTIVE: The purpose of this study was to quantify the cross-sectional area (CSA) of the peroneus brevis, the peroneus longus, and connective tissue; to compare these measures in participants with and without lateral ankle sprains (LAS); and to determine the intraexaminer reliability of the protocol used to acquire these measures. METHODS: A cross-sectional case-control study was undertaken. B-mode ultrasound imaging was performed to measure the resting CSA and circular perimeter of the muscles and connective tissue and the total area and ratio between the CSA of the peroneus longus and the peroneus brevis. The imaging was performed for 56 feet, 28 with LAS and 28 without LAS (the mean numbers ± SD of total LAS, grade-I LAS and grade-II LAS were 4.1 ± 3.6, 2.71 ± 3.2, and 1.39 ± 0.9, respectively). A univariate correlation analysis using Pearson (r) and the Kendall tau_b (τB) coefficients was performed to evaluate the ultrasound imaging measurements (α = 0.05). RESULTS: Statistically significant differences (P < .05) were observed between the 2 groups, with a moderate negative correlation for the circular perimeter of the peroneus longus (P = .001; r = -0.444) and a weak association for the CSA of the peroneus longus (P = .002; τB = - 0.349), the ratio between the CSA of the peroneus longus and the peroneus brevis (P = .008; τB = -0.293), and the circular perimeter of connective tissue (P = .013; τB = -0.277). CONCLUSIONS: The peroneus longus CSA is reduced in participants with LAS compared with that in participants without LAS. The intraexaminer reliability of the ultrasonography protocol was excellent when quantifying the peroneus brevis and the peroneus longus muscle tissues and acceptable when quantifying connective tissue.

Influence of depression in a sample of people with hallux valgus.

Hallux valgus (HV) is a highly-prevalent forefoot deformity associated with progressive subluxation and osteoarthritis of the first metatarsophalangeal joint; it is believed to be associated with depression. The aim of the present study was to determine the association of patients with varying degrees of HV involvement to depression using the Beck Depression Inventory (BDI). The sample consisted of 102 participants (mean age: 45.1 ± 1.6), who attended an outpatient centre where self-report data were recorded. The degree of HV deformity was determined in both feet, and the scores on the BDI were compared. A total of 38.24% of the sample had depression, with an average BDI score of 10.55 ± 12.36 points. There was a statistically-significant association between the degree and presence of HV in both feet (P = 0.0001). People with a greater degree of HV deformity in any foot also have a significant increase in depression based on BDI scores, regardless of sex.

Quality of Life Impact Related to Foot Health in a Sample of Older People with Hallux Valgus.

Hallux Valgus (HV) is a highly prevalent forefoot deformity in older people associated with progressive subluxation and osteoarthritis of the first metatarsophalangeal (MTP) joint and it is believed to be associated with varying degrees of HV effect on the quality of life related to foot health. The aim of this study is to compare the impact of varying degrees of HV on foot health in a sample of older people. The sample consisted of 115 participants, mean age 76.7 ± 9.1, who attended an outpatient center where self-report data were recorded. The degree of HV deformity was determined in both feet using the Manchester Scale (MS) from stage 1 (mild) to 4 (very severe). Scores obtained on the Foot Health Status Questionnaire (FHSQ) were compared. This has 13 questions that assess 4 health domains of the feet, namely pain, function, general health and footwear. The stage 4 of HV shown lower scores for the footwear domain (11.23 ± 15.6); general foot health (27.62 ± 19.1); foot pain (44.65 ± 24.5); foot function (53.04 ± 27.2); vigour (42.19 ± 16.8); social capacity (44.46 ± 28.1); and general health (41.15 ± 25.5) compared with stage 1 of HV (P<0.05) and there were no differences of physical activity (62.81 ± 24.6). Often, quality of life decreases in the elderly population based in large part on their foot health. There is a progressive reduction in health in general and foot health with increasing severity of hallux valgus deformity which appears to be associated with the presence of greater degree of HV, regardless of gender.

Effects of digital tourniquet ischemia: a single center study.

BACKGROUND: There is little information regarding the detrimental effects of tourniquet ischemia, although it is a widely used technique in extremity surgery. We endeavored to study some of the physiologic changes involved in the finger during the ischemic phase and throughout the recovery phase after tourniquet release. MATERIALS AND METHODS: This was a single-center, prospective observational study involving healthy adults designed to assess the appropriate application time of a digital T-ring tourniquet without a pH or acidosis <7.0 to avoid any potential risk to local tissues. RESULTS: There was no pH difference before tourniquet application between men and women, but after tourniquet application, the women's fingers became more acidotic at 10 and 20 minutes than the mens', but after 30 minutes the acidosis of the two groups was similar. Participants who weighed less had a more acidotic pH level than heavier participants. LIMITATIONS: This study was performed in a laboratory setting on healthy people rather than on those with existing medical conditions, so clinical recommendations cannot be explicitly made. CONCLUSION: Tourniquet application time is precious. While operating under tourniquet control, the extremity becomes increasingly acidotic. Tourniquet ischemia longer than 20 minutes causes local acidosis and muscle fatigue. Women and persons who weighed less could reach acidotic pH values faster than men or heavier patients. If applications longer than 20 minute are expected, the tourniquet should be released at 20 minutes, allowing the finger to reperfuse for 3-5 minutes to clear the acidosis before reapplication of tourniquet.
