[Purpose] This study proposed a new neck support tying (NST) method using Thera-Band for
the prevention of neck and shoulder pain in workers doing overhead work. The purpose of
this study was to investigate the effect of the new NST method using Thera-Band on
cervical ROM and shoulder pain after overhead work. [Subjects] Fourteen male subjects were
recruited. [Methods] This study measured the cervical ROM and pressure pain threshold
(PPT) of the upper and middle trapezius (UT and MT) muscles after the control and NST
groups had performed overhead work. [Results] The cervical flexion, extension, and lateral
flexion angles of the NST group were significantly larger than those of the control group.
The PPTs of UT and MT of the NST group were significantly higher than those of the control
group [Conclusion] The NST prevented ROM reduction and pain in the cervical and shoulder
regions.Key words: Neck supporter, Overhead work, Thera-Band 相似文献

[Purpose] The purpose of this study was to verify the efficacy of a pelvic floor muscle
exercise program by comparing subjects’ muscle thickness with changes in vaginal pressure.
[Subjects] Two groups of female participants without a medical history of pelvic floor
muscle dysfunction were evaluated. The mean age of Group I was 33.5 years and that of
Group II was 49.69 years. [Methods] The participants were instructed to perform a pelvic
floor muscle contraction. While measuring the vaginal pressure of the pelvic floor muscle,
biofeedback was given on five levels, and the thicknesses of the transversus abdominis,
external oblique, and internal oblique muscles were measured with ultrasound. [Results]
The thickness of the transversus abdominis muscle was significantly increased at 30
cmH2O in Group I, and at 20 cmH2O in Group II. The thickness of
the internal oblique abdominal muscle significantly increased at maximum contraction in
Group II. [Conclusion] Different abdominal muscles contracted depending on vaginal
pressure. The result may be used to create and implement an exercise program that
effectively strengthens the pelvic floor muscles.Key words: Pelvic floor muscle contraction, Vaginal pressure, Abdominis muscle 相似文献

The purpose of the present study was to compare the contraction ability at maximum
expiration of the transversus abdominis (TrA) in patients with chronic low-back pain
(CLBP) with that of healthy individuals. [Subjects] We studied 15 patients with CLBP and
15 healthy subjects. The subjects were informed of the study''s aim and methods, and the
experiment was performed after obtaining the consent of the subjects. [Methods] The
thickness of the abdominal muscles was measured using a LOGIQ Book XP (GE, USA). The main
outcome variable was the ratio of TrA thickness at maximum expiration versus in the
relaxed position (TrA activation ratio). [Results] There was a difference between the
healthy subjects and the back pain subjects with regard to the thickness of the TrA at
rest and the thickness of the muscle during contraction. However, there was no difference
in the rate of change in the muscle activity. [Conclusion] In conclusion, CLBP patients
exhibited atrophy of the TrA muscle, but voluntary TrA muscle activation was similar to
that of the normal subjects.Key words: Low back pain, Transversus abdominis, Maximum expiration 相似文献

[Purpose] This study examined differences in neck muscle activity in two different head
positions during tackles with the aim of contributing to the prevention of sports
injuries. [Subjects] The subjects were 28 male high-school rugby players. [Methods] Two
tackle positions were considered: a head-up position and a head-down position. Muscle
activities of the sternocleidomastoid muscles and the upper, middle, and lower parts of
the trapezius muscles were measured. [Results] Muscle activities of the
sternocleidomastoid muscles and the right upper trapezius muscle were significantly
increased in the head-up position, and the activity of the lower trapezius was
significantly increased in the head-down position. [Conclusion] Tackling with the head-up
position increases neck muscle activity and stability of the head and the neck.Key words: Sternocleidomastoid muscle, Trapezius muscle, Rugby 相似文献

[Purpose] The aim of this study was to investigate muscle thickness changes in the
external oblique (EO), internal oblique (IO), and transversus abdominis (TrA) muscles
between the neutral position and trunk rotation, under a state of rest without voluntary
contractions, and isometric contractions to both sides with resistance of 50% of the
maximum trunk rotation strength. [Subjects] The subjects of this study were 21 healthy
young men. [Methods] Muscle thickness changes in the EO, IO, and TrA in each position and
state were evaluated by ultrasound. The range of motion at maximum trunk rotation and the
maximum strength of trunk rotation were measured using a hand-held dynamometer. [Results]
In the neutral position and at 50% trunk rotation to the right side, the thicknesses of
the IO and TrA significantly increased with resistance. In both states, the thicknesses of
the IO and TrA significantly increased at 50% trunk rotation to the right side.
[Conclusion] The muscular contractions of the IO and TrA were stronger during ipsilateral
rotation than in the neutral position and with resistance than at rest. Moreover, the
muscular contraction was strongest in the resistive state during ipsilateral rotation.Key words: Trunk rotation, Low back pain, Functional evaluation 相似文献

Older adults who require nursing care have joint contractures characterized by limited range of motion (ROM). The present study investigated age-related muscle changes using ultrasonography and the relationship between ROM and muscle changes in older adults. Twenty-two healthy young adults (mean age: 23.3 y) and 60 hospitalized older adults (mean age: 86.1 y) participated. ROM of hip abduction was measured using a goniometer. Echo intensity (EI), reflecting interstitial fibrous tissue or fat within adductor longus (ADDl) was measured using B-mode ultrasonography, and strain ratio (SR), reflecting ADDl stiffness, was measured by strain elastography. The Mann–Whitney U-test and Spearman's correlation test were used for analysis. The ROM and SR of older adults were significantly lower than those of young adults (both p values <0.001). The EI was significantly higher in older adults than in young adults (p < 0.001). In older adults, the SR was moderately correlated with ROM (ρ = 0.49, p < 0.001). In conclusion, limited ROM and increase in interstitial fibrous tissue or fat and stiffness occur with aging, and the SR measured by strain elastography is useful for investigating the effect of muscle stiffness on the ROM of hospitalized older adults. 相似文献

Muscle thickness is one of the most widely used parameters for quantifying muscle function. Ultrasonography is frequently used to estimate changes in muscle thickness in both static and dynamic contractions. Conventionally, most such measurements are conducted by manual analysis of ultrasound images. This manual approach is time consuming, subjective, susceptible to error and not suitable for measuring dynamic change. In this study, we developed an automated tracking method based on an optical flow algorithm using an affine motion model. The goal of the study was to evaluate the performance of the proposed method by comparing it with the manual approach and by determining its repeatability. Real-time B-mode ultrasound was used to examine the rectus femoris during voluntary contraction. The coefficient of multiple correlation (CMC) was used to quantify the level of agreement between the two methods and the repeatability of the proposed method. The two methods were also compared by linear regression and Bland-Altman analysis. The findings indicated that the results obtained using the proposed method were in good agreement with those obtained using the manual approach (CMC = 0.97 ± 0.02, difference = −0.06 ± 0.22 mm) and were highly repeatable (CMC = 0.91 ± 0.07). In conclusion, the automated method proposed here provides an accurate, highly repeatable and efficient approach to the estimation of muscle thickness during muscle contraction. 相似文献

Objective. The purpose of this study was to construct nomograms of placental volumes according to gestational age and estimated fetal weight. Methods. From March to November 2007, placental volumes were prospectively measured by ultrasonography in 295 normal pregnancies from 12 to 40 weeks' gestation and correlated with gestational age and estimated fetal weight. Inclusion criteria were healthy women, singleton pregnancies with normal fetal morphologic characteristics on ultrasonography, and confirmed gestational age by first‐trimester ultrasonography. Results. The mean placental volume ranged from 83 cm3 at 12 weeks to 427.7 cm3 at 40 weeks. Linear regression yielded the following formula for the expected placental volumes (ePV) according to gestational age (GA): ePV (cm3) = ?64.68 + 12.31 × GA (r = 0.572; P < .001). Placental volumes also varied according to estimated fetal weight (EFW), and the following mathematical equation was also obtained by linear regression: ePV = 94.19 + 0.09 × EFW (r = 0.505; P < 0.001). Conclusions. Nomograms of placental volumes according to gestational age and estimated fetal weight were constructed, generating reference values. 相似文献

[Purpose] The purpose of this study was to investigate the relationship between age and
the maximum pelvic anteversion and retroversion angles, as well as the associated pelvic
range of motion, measured in a sitting position with free knee movement. [Subjects] A
total of 132 healthy volunteers (74 women, 58 men; age range, 20–79 years) were divided
into six groups based on age (20–29, 30–39, 40–49, 50–59, 60–69, and 70–79 years).
[Methods] The maximum pelvic anteversion and retroversion angles were measured manually
five times by a goniometer in a sitting position that allowed free movement of the knee
joints. [Results] There was a significant effect of age group on the maximum pelvic
anteversion and retroversion angles and pelvic range of motion (the difference between
these angles). There was a significant correlation between age and the maximum pelvic
anteversion angle, maximum pelvic retroversion angle, and pelvic range of motion.
[Conclusion] The maximum pelvic anteversion and retroversion angles and pelvic range of
motion were significantly correlated with age. The maximum pelvic anteversion angle and
pelvic range of motion were most affected by age.Key words: Aging, Mobility limitation, Pelvis 相似文献

[Purpose] This study aimed to identify the effects of cervical deep muscle strengthening
(CDS) on neck pain in a patient with Klippel-Feil syndrome (KFS). [Subjects and Methods]
The subjects was a 39 year-old woman with neck pain and KFS that included incomplete block
vertebrae in the C2–3 segments and block vertebrae in the C6–7 segments. The subject
performed an exercise program including cervical strengthening exercise (level 1) and CDS
exercise (level 2) for 6 weeks. Neck pain intensity was measured using the visual analogue
scale (VAS) and the pressure pain threshold (PPT). All measurements were obtained before
and after the CDS exercise program. [Results] The VAS and PPT measurements decreased;
range of motion in the cervical joint increased. [Conclusion] CDS exercises were effective
interventions for reducing neck pain in a patient with Klippel-Feil syndrome.Key words: Cervical deep muscle strengthening, Neck pain, Klippel-Feil syndrome 相似文献

[Purpose] The purpose of this study is to examine the effects on respiratory function
and oxygen saturation of intermittent life in the uplands at an altitude above sea level
of approximately 850 m. [Subjects and Methods] The study subjects were on 100 female
student subjects attending a university located in the uplands. The subjects’ oxygen
saturation, heart rates and respiratory functions were measured at the university, which
has campuses both in the uplands and the lowlands. [Results] Freshmen showed differences
in oxygen saturation, heart rate, and most respiratory function items between the
different altitudes; however, seniors did not exhibit any differences. There were no
differences in oxygen saturation and heart rate between the uplands and the lowlands
either group. In the uplands, peak forced expiratory flow was shown to be high in the
seniors, who also had better cardiopulmonary function. [Conclusion] Senior students, who
had been exposed to the upland environment for a longer period of time, generally showed
better respiratory function. Therefore, alternating living between the uplands and the
lowlands can be said to improve an individual’s respiratory function.Key words: Altitude above sea level, Oxygen saturation, Respiratory function 相似文献

Acoustic cavitation-mediated wounding (i.e., sonoporation) has great potential to improve medical and laboratory applications requiring intracellular uptake of exogenous molecules; however, the field lacks detailed understanding of cavitation-induced morphologic changes in cells and their relative importance. Here, we present an in-depth study of the effects of acoustic cavitation on cells using electron and confocal microscopy coupled with quantitative flow cytometry. High resolution images of treated cells show that morphologically different types of blebs can occur after wounding conditions caused by ultrasound exposure as well as by mechanical shear and strong laser ablation. In addition, these treatments caused wound-induced nonlytic necrotic death resulting in cell bodies we call wound-derived perikarya (WD-P). However, only cells exposed to acoustic cavitation experienced ejection of intact nuclei and nearly instant lytic necrosis. Quantitative analysis by flow cytometry indicates that wound-derived perikarya are the dominant morphology of nonviable cells, except at the strongest wounding conditions, where nuclear ejection accounts for a significant portion of cell death after ultrasound exposure.

[Purpose] The purpose of the present study was to investigate the reliability of
isometric knee extension muscle strength measurement of patients who underwent femoral
neck fracture surgery, as well as the relationship between independent mobility in the
ward and knee muscle strength. [Subjects] The subjects were 75 patients who underwent
femoral neck fracture surgery. [Methods] We used a hand-held dynamometer and a belt to
measure isometric knee extension muscle strength three times, and used intraclass
correlation coefficients (ICCs) to investigate the reliability of the measurements. We
used a receiver operating characteristic curve to investigate the cutoff values for
independent walking with walking sticks and non-independent mobility. [Results] ICCs (1,
1) were 0.9 or higher. The cutoff value for independent walking with walking sticks was
0.289 kgf/kg on the non-fractured side, 0.193 kgf/kg on the fractured side, and the
average of both limbs was 0.238 kgf/kg. [Conclusion] We consider that the test-retest
reliability of isometric knee extension muscle strength measurement of patients who have
undergone femoral neck fracture surgery is high. We also consider that isometric knee
extension muscle strength is useful for investigating means of independent mobility in the
ward.Key words: Muscle strength, Test-retest reliability, Independent walking 相似文献

[Purpose] This study investigated the changes in electromyographic (EMG) activities of
the infraspinatus and posterior deltoid muscles during shoulder external rotation under
open kinetic chain (OKC) and closed kinetic chain (CKC) exercise conditions. [Subjects] In
total, 15 healthy males participated in this study. [Methods] Subjects performed shoulder
external rotations under CKC and OKC conditions while standing with and without weight
support provided by a height-adjustable table. Pressure biofeedback was used to ensure a
constant amount of weight support. The activities of the infraspinatus and posterior
deltoid muscles during shoulder external rotation were measured using a wireless surface
EMG system. The paired t-test was used to compare the EMG activities of the infraspinatus
and the posterior deltoid muscles and the ratio of the infraspinatus to the posterior
deltoid during shoulder external rotation under OKC and CKC conditions. [Results] The EMG
activity of the infraspinatus and the ratio of the infraspinatus to the posterior deltoid
activities were significantly increased, whereas the posterior deltoid activity was
significantly decreased under the CKC condition compared to the OKC condition.
[Conclusion] Clinicians should consider the CKC shoulder external rotation exercise when
they wish to selectively strengthen the infraspinatus.Key words: Infraspinatus, Posterior deltoid, Selective muscle strengthening 相似文献

[Purpose] This study was conducted in order to investigate the importance of trunk
muscle strength in stroke patients. By comparing the thicknesses of the abdominal wall
muscles through ultrasonography, relative to the duration of illness, the results of the
objective data were applied. [Methods] Thirty stroke patients were divided into three
groups including an acute phase group participating in the study within 1 month after the
onset of a stroke (n=10), a subacute phase group participating less than 6 months (n=10)
after a stroke, and a chronic phase group participating more than 6 months (n=10) after
suffering a stroke. The thicknesses of the transversus abdominis muscles (TrA), internal
oblique muscle (IO), and the external oblique muscle (EO) were measured at rest and during
abdominal draw-in maneuver (ADIM) in a supine hook-lying position, and their differences
were compared. [Results] The results showed that, in comparison of the thicknesses of the
paretic and nonparetic sides, the TrA of the subacute phase and chronic phase groups
showed significant differences. In addition, the IO of the subacute phase group and the EO
of the chronic phase groups also showed significant differences. [Conclusion] According to
the duration of illness in stroke patients, the abdominal wall muscles become noticeably
infirm and asymmetric. By improving their symmetry, the functions of the trunk muscles can
be recovered.Key words: Stroke, Sonographic image, Abdominal wall muscles 相似文献

[Purpose] The purpose of the present study was to examine the amount of change in the
thicknesses of the deep cervical flexor (DCF) and sternocleidomastoid (SCM) muscles in
subjects with neck pain and subjects without neck pain during craniocervical flexion
exercise (CCFE). [Subjects] The total number of subjects was 40, comprising 20 in the
no-pain group (males 11, females 9) and 20 in the pain group (males 8, females 12).
[Methods] Muscle images were obtained using ultrasound, and the thicknesses of the
individual muscles were measured using the NIH ImageJ software. [Results] During CCFE, as
pressure increased, the no-pain group recruited the DCF more than the pain group, while
the pain group recruited the SCM more. [Conclusion] Selective DCF contraction exercises
are considered very useful in the treatment of patients with neck pain.Key words: Craniocervical flexion exercise, Deep cervical flexor, Sternocleidomastoid 相似文献
