“…7 From a clinical perspective, the LC and SCM could be strengthened with craniocervical-flexion exercise (using a pressure cuff to apply downward pressure to a bowed head in a supine position for 10 seconds for 10 repetitions) and cervicalflexion exercise (lifting or flexing the head through the full range of motion for 3 sets of 15 repetitions), respectively, for 10 weeks. 17 The authors 17 reported increases in LC CSA of 0.167 cm 2 and SCM thickness of 0.733 cm in individuals with chronic NP. Based on the current MDC values (Table 3), the change in LC CSA of 0.293 cm 2 and in SCM thickness of 0.176 cm after interventions would be clinically meaningful.…”

“…For the cervical-flexor muscles, the CSA of the LC and thickness of the SCM were measured on the same image. 17 Participants were supine on an examination table with a folded towel under the neck to position it in slight extension. They were asked to relax as much as possible and close their eyes if they preferred.…”

“…This imaging was also used to assess the effects of 2 types of interventions (craniocervical-flexion exercises and standard cervical-flexion exercises) in individuals with NP. 17 However, justification for the use of US-based imaging in young and athletic individuals is scarce. As the first step, it is critical to establish the reliability and normative values of US-based imaging of the cervical muscles in young, athletic men and women.…”

Context Neck pain (NP), neck injuries, and concussions are more prevalent in female athletes than in their male counterparts. Females exhibit less neck girth, strength, and stiffness against a perturbation. As part of the clinical examination for individuals with NP, ultrasound (US)–based imaging of the cervical muscles has become common. Muscle size or thickness and stiffness can be measured with US-based B-mode and shear-wave elastography (SWE), respectively. Information on reliability, normative values, and sex differences based on US-based muscle size or thickness and stiffness in young and athletic individuals is limited. Objective To evaluate sex differences in US-based muscle size or thickness and biomechanical properties of the cervical-flexor and -extensor muscles. Design Cross-sectional study. Setting Laboratory. Patients or Other Participants A total of 13 women (age = 23.7 ± 1.9 years, height = 167.1 ± 6.1 cm, mass = 63.8 ± 5.6 kg) and 11 men (age = 25.6 ± 4.9 years, height = 178.7 ± 8.3 cm, mass = 78.9 ± 12.0 kg). Main Outcome Measure(s) The same examiner collected all measures, using US B-mode to scan the cross-sectional area and thickness of the longus colli (LC), sternocleidomastoid (SCM), cervical-extensor muscles, and upper trapezius (UT) muscle. The US SWE-mode was used to measure the stiffness of the SCM and UT. Independent t tests or Mann-Whitney U tests were calculated to determine sex differences. The intraclass correlation coefficient (ICC) measured intrarater test-retest reliability. Results Men had thicker SCMs than women (P = .01). No sex differences were present for longus colli cross-sectional area, cervical-extensor muscle thickness, or UT thickness (P > .05). In addition, no sex differences were evident for SCM (P = .302) or UT (P = .703) SWE stiffness. Reliability was good to excellent (ICC = 0.715–0.890) except for SCM SWE stiffness (ICC = 0.554). Conclusions The only sex difference was in SCM thickness. However, smaller SCMs in women did not result in less SCM SWE stiffness. We provided normative values for US-based imaging of the cervical-flexor and -extensor muscles in young and athletic men and women.

“…With respect to the temporomandibular region, the function of the masseter, temporalis, and sternocleidomastoid muscles has been linked with temporomandibular joint disorders [8]. Javanshir et al [9,10] showed that monitoring deep cervical flexor muscles with ultrasonography may be carried out during training programs for patients with chronic neck pain. In the trunk region, multifidus and abdominal wall muscles have been related to lumbopelvic pain (LPP) [11,12].…”

The aim of the present study was to evaluate and compare with rehabilitative ultrasound imaging (RUSI) abdominal wall muscle thickness and interrecti distance (IRD) between elite and amateur basketball players. A sample of 32 basketball players (age: 23.0 ± 8.5; height: 1.89 ± 14.25 m; weight: 86.6 ± 15.5 kg; body mass index: 22.8 ± 2.6 kg/m 2 ) was divided in two groups: professional elite and amateur players. A diagnostic ultrasound tool with a 7-14 MHz range linear transducer was used for B mode ultrasound imaging. Ultrasound images of the external oblique (EO), internal oblique (IO), transversus abdominis (TrAb), and rectus anterior (RA) muscles as well as IRD were measured and analyzed by ImageJ software. Statistically significant differences (p < 0.05) with greater height, weight, and Nijmegen scores were shown in favor of the elite basketball players compared to the amateur basketball players. Ultrasound measurements of the abdominal wall muscles showed statistically significant differences (p < 0.05) for increased IRD and left TrAb thickness and decreased right and left EO thickness in favor of the elite versus amateur basketball players. The rest of the measurements did not show any statistically significant differences (p > 0.05). Increased IRD and TrAb thickness and reduced EO thickness may be shown in elite versus amateur basketball players.

“…11 Furthermore, CSA of intrinsic hand muscles can be evaluate with RUSI and could be reliable to predict muscle strength in subjects with nerve injury. 12 With respect to cervical muscles, Javanshir et al 13 observed that deep cervical flexor muscles may be evaluated during programs for individuals with neck pain. Temporomandibular joint disorders have showed an altered function of the masseter, temporalis and sternocleidomastoid muscles.…”

SUMMARY 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.
