[Purpose] The aim of this study was to reveal the effect of expiratory muscle fatigue
(EMF) on respiratory response under two different exercise conditions: exercise (EX) with
EMF (EMF-EX) and control EX without EMF (CON-EX). [Methods] Nine healthy adult men
performed cycle exercise with a ramp load, and a spirometer was used to measure forced
vital capacity (FVC), forced expiratory volume in one second, percent of forced expiratory
volume, maximal expiratory mouth pressure, and maximal inspiratory mouth pressure
(PImax) to evaluate respiratory functions immediately and at 15 and 30 min
after exercise. To assess the respiratory response during exercise, an exhaled gas
analyzer was used to measure minute ventilation (VE), respiratory frequency
(f), tidal volume (VT), oxygen uptake, and carbon dioxide output. In addition,
the Borg Scale was used to evaluate dyspnea, while electrocardiography was used to measure
heart rate. [Results] The results showed that compared with the CON-EX condition, no
change in VE, an increase in f, or a decrease in VT was observed
under the medium-intensity EMF-EX condition, while high-intensity exercise reduced
VE and f without changing VT. [Conclusion] These results suggest
that during medium-intensity exercise, EMF modulates the respiratory response by inducing
shallow and fast breathing to increase ventilation volume.Key words: Expiratory muscle fatigue, Maximal mouth pressure, Respiratory response 相似文献

[Purpose] Smartphone use reportedly changes posture. However, how neck posture is altered
in smartphone users with neck pain is unknown. This study examined changes in the posture
of young adults with and without mild neck pain (MNP) when using a smartphone. [Subjects]
Thirteen control subjects and 14 subjects with MNP who used smartphones were recruited.
[Methods] The upper cervical (UC) and lower cervical (LC) angles in the sagittal plane
were measured using an ultrasound-based motion analysis system while the seated subjects
used a smartphone for 5 min. [Results] During smartphone use, the MNP group exhibited
greater UC and LC flexion angles than the control group. [Conclusion] These findings
suggest that young adults with MNP are more careful and more frequently utilize a neutral
neck posture than young adults without MNP when using a smartphone while sitting.Key words: Smartphone, Cervical flexion, Young adult 相似文献

[Purpose] This study measured %isolation and investigated whether it shows a difference
between the presence and absence of wrist joint restriction, as well as changes in muscle
activity patterns. [Methods] Twenty subjects performed upper extremity functional movement
in the Manual Function Test (MFT) with and without wrist restriction, and the muscle
activities of the trapezius, middle deltoid, biceps brachii, triceps brachii, extensor
carpi radialis, and flexor carpi radialis were recorded. When there were differences in
muscle activation, %isolation was implemented and the changes in the muscle activity
patterns were noted. [Results] In the grasping and pinching tasks, there was a significant
increase in %isolation of the upper trapezius and a significant decrease in %isolation of
the extensor carpi radialis. Carrying a cube task, %isolation of the upper trapezius and
middle deltoid significantly increased, whereas %isolation of the triceps brachii and
extensor carpi radialis significantly decreased. In the pegboard task, the %isolation
values of the extensor carpi radialis and flexor carpi radialis significantly decreased.
[Conclusion] The data of this study should be useful for therapists, who can employ the
information as material for the education and treatment of patients with wrist joint
restriction. Therapists may thus look for ways to improve the quality of mobility by
predicting the complement mobility depending on the activity performed and then determine
whether to facilitate or restrict mobility.Key words: Functional upper extremity activity, %isolation, Wrist joint restriction 相似文献

[Purpose] The purpose of our study was to clarify temporal effects on restrictions to
range of motion and the histopathological changes of joint components after joint
immobilization in a rat knee-contracture model. [Subjects] Fifty-four male Wistar rats
were randomly divided into two groups: a fixation group, and a control group. [Methods] In
the fixation group, unilateral knee joints were immobilized at full flexion using a
plaster cast for 4 weeks. At four weeks the animals were randomly divided into six
subgroups, corresponding to the time of examination after cast removal: 0, 4, 8, 16, 24,
and 32 weeks. For comparison, control group animals of corresponding age were also
examined. [Results] Although movement restrictions of the knee joint had completely
recovered 6 weeks after the cast removal, cartilage and synovial membrane structures did
not completely recover. [Conclusion] These findings have not previously been reported, and
as they form an addition to the fundamental scientific foundations of physical therapy,
further research must examine these findings from a variety of perspectives.Key words: Contracture, Articular cartilage, Synovial membrane 相似文献

Effect of Assistive Device for Neck Retraction (ANR) on Neck Muscles during
Neck Retraction Exercise
[Purpose] The purpose of present study was to develop an exercise device for assisting
neck retraction exercise and to investigate its effectiveness. [Subjects] Fifteen male
subjects were recruited. [Methods] The subjects performed the neck retraction exercises
with and without assistive device for neck retraction (ANR). EMG activities of the lower
cervical erector spinae (LCE), and sternocleidomatoid (SCM) muscles were recorded.
[Results] The ANR condition significantly increased LCE activation compared to the control
condition. The ANR condition significantly decreased SCM activation compared to the
control condition. [Conclusion] We suggest that the ANR condition will help the efficacy
of the neck retraction exercise.Key words: Electromyography, Forward head posture, Neck retraction exercise 相似文献

[Purpose] The aim of this study was to investigate the effect of kinesio taping (KT) on
the kinematics of the lumbo-pelvic-hip complex during forward bending by individuals with
reduced hamstring extensibility. [Subjects] Eighteen males with reduced hamstring
extensibility were randomly assigned to one of two groups:, the hamstring KT group (n=9),
or the sham KT group (n=9). [Methods] The kinematics of the lumbopelvic-hip complex during
lumbar forward bending was measured using a motion capture system before and after
applying KT. [Results] The angle of lumbar flexion during late lumbar forward bending
increased significantly post-KT compared to pre-KT measurements in the hamstring KT group.
[Conclusion] These findings suggest that KT does not directly affect an individual’s
movement during lumbar forward bending.Key words: Kinematics, Kinesio taping, Lumbar forward bending 相似文献

[Purpose] This study investigated the optimal thickness of the wheelchair backrest for
lumbar load and increased comfort. [Subjects] Fifteen healthy people participated.
[Methods] The study examined three randomized backrest conditions: no pad; a 3-cm-thick
lumbar pad; and a 6-cm-thick lumbar pad. The location of the lumbar pad was standardized
at the mid-lumbar level (L3). Participants were instructed to propel the wheelchair using
only the handrims. [Results] Activation of the anterior deltoid, upper trapezius, and
biceps brachii muscles was significantly reduced when the participants used the 3-cm pad
compared to no pad, while it was significantly increased in the anterior deltoid, upper
trapezius, posterior deltoid, and biceps brachii when the participants used the 6-cm pad
compared to the 3-cm pad. Muscle activation did not differ significantly between the no
pad and the 6-cm lumbar pad conditions. [Conclusion] A lumbar pad decreased the activation
of the upper extremity muscles. We believe that padding of the appropriate thickness will
lead to effective muscle activation while propelling a wheelchair and decrease the risk of
musculoskeletal disease.Key words: Electromyography, Lumbar pad, Wheelchair 相似文献

[Purpose] This study was performed to investigate the histological changes that occur in
the periphery of the sciatic nerve in rats undergoing knee immobilization. [Subjects and
Methods] 29 male 9-week-old Wistar rats were divided randomly into a control group (C
group, n = 7) and an immobilized group (I group, n = 22). The animals in the I group had
the left knee joint immobilized in maximal flexion with plaster casts for two weeks. After
the experimental period, we obtained cross-sections of tissues from the center of the left
thigh, and the periphery of the sciatic nerve was observed under an optical microscope
after hematoxylin-eosin staining. [Results] In contrast to the rats of C group, the rats
in I group showed adherence between the bundle of nerve fibers and perineurium, as well as
thickening of the perineurium. These histological changes were statistically significant.
[Conclusions] Immobilization of the knee joints of rats resulted in characteristic
histological changes in the connective tissue around the sciatic nerve.Key words: Contracture, Sciatic nerve, Perineurium 相似文献

[Purpose] The purpose of this study was to determine the effects of lumbar joint
mobilization on the joint position sense (JPS) of normal adults. [Subjects] A total of 30
normal adults were divided into an experimental group (n = 15) and a control group (n =
15). [Methods] The experimental group received lumbar joint mobilization and massage, and
the control group received massage only. Both the experimental and control groups were
evaluated for joint position error (JPE) by using a digital dual inclinometer before and
after the experiment. [Results] In the before and after comparison for the experimental
group, statistically significant differences were found in flexion, extension, left
lateral flexion, and right lateral flexion. There was no statistically significant
difference in the before and after comparison for the control group. [Conclusion] Because
lumbar joint mobilization can reduce JPE and improve JPS, its use in the treatment of
patients with lumbar problems is recommended.Key words: Gong’s mobilization, Joint position sense, Joint position error 相似文献

Background:
Hippotherapy uses horseback riding movements for therapeutic purposes. In addition to the horse''s movement, the choice of equipment and types of floor are also useful in the intervention. The quantification of dynamic parameters that define the interaction of the surface of contact between horse and rider provides insight into how the type of floor surface variations act upon the subject''s postural control.Objective:
To test whether different types of surfaces promote changes in the amplitude (ACOP) and velocity (VCOP) of the center of pressure (COP) displacement during the rider''s contact with the saddle on the horse''s back.Method:
Twenty two healthy adult male subjects with experience in riding were evaluated. The penetration resistances of asphalt, sand and grass surfaces were measured. The COP data were collected on the three surfaces using a pressure measurement mat.Results:
ACOP values were higher in sand, followed by grass and asphalt, with significant differences between sand and asphalt (anteroposterior, p=0.042; mediolateral, p=0.019). The ACOP and VCOP values were higher in the anteroposterior than in the mediolateral direction on all surfaces (ACOP, p=0.001; VCOP, p=0.006). The VCOP did not differ between the surfaces.Conclusion:
Postural control, measured by the COP displacement, undergoes variations in its amplitude as a result of the type of floor surface. Therefore, these results reinforce the importance of the choice of floor surface when defining the strategy to be used during hippotherapy intervention. 相似文献12.

[Purpose] To clarify how a novel dynamic cushion affects the leg edema evoked by
wheelchair sitting, we measured the changes in leg volume induced during wheelchair
sitting with the dynamic air cushion or a static cushion. [Subjects and Methods] Nine
healthy male subjects participated in this study. Leg edema during wheelchair sitting was
evaluated with strain gauge plethysmography (the gauge was placed around the middle
portion of the lower thigh). Following a period of rest, each subject was asked to sit on
a wheelchair containing the dynamic cushion for 15 min. Then, the protocol was repeated
with a static cushion. The angles of the knee and ankle joints were set to 90 degrees, and
no footrests were used. [Results] The change in leg volume observed during sitting on the
dynamic cushion (0.00 ± 0.03 mL/100 mL) was smaller than that observed during sitting on
the static cushion (0.02 ± 0.02 mL/100 mL). [Conclusion] These results suggested that the
dynamic cushion relieved leg edema during wheelchair sitting.Key words: Wheelchair cushion, Leg volume, Healthy human 相似文献

[Purpose] This study investigated the effects of accuracy constraints (targets) placed on
the stepping-limb heel-strike (HS) on the electromyogram (EMG) and ground reaction forces
(GRFs) during gait initiation. [Subjects and Methods] Twenty healthy subjects (29.2 ±
2.9 years) were asked to begin walking or stepping over a 10-cm-high obstacle at a fast
speed. A 3-cm-diameter target was placed on the ground to dictate the position and
accuracy of the stepping-limb HS. [Results] The results showed that the initiation
velocity increase in the no-target conditions was due to modulation of the stance- and
stepping-limb GRFs and a corresponding increase in the tibialis anterior (TA) activities
of both limbs before stepping-limb toe-off. This was achieved by significantly increasing
the stepping- and stance-limb TAEMG1 (determined between the onset of movement and time to
peak anteroposterior (A-P) GRF of the stepping- and stance- limb) for the no-target
conditions. It seems, therefore, that TAEMG1 and the slope to stepping-limb peak A-P GRF
contributed to the intended velocity of initiation. [Conclusion] These data indicate that
gait initiation and/or stepping over an obstacle may prove to be tasks by which motor
control can be measured. The present study provides insight into the working mechanisms of
the stepping and stance limbs and shows a clear need to further investigate whether the
intact or affected limb should be used to initiate gait during rehabilitation and
prosthetic training.Key words: Electromyogram, Gait initiation, Ground reaction forces 相似文献

[Purpose] VO2 is expressed as the product of cardiac output and O2
extraction by the Fick equation. During the incremental exercise test and constant
high-intensity exercise test, VO2 results in the attainment of maximal
O2 uptake at exhaustion. However, the differences in the physiological
components, cardiac output and muscle O2 extraction, have not been fully
elucidated. We tested the hypothesis that constant exercise would result in higher
O2 extraction than incremental exercise at exhaustion. [Subjects] Twenty-five
subjects performed incremental exercise and constant exercise at 80% of their peak work
rate. [Methods] Ventilatory, cardiovascular, and muscle oxygenation responses were
measured using a gas analyzer, Finapres, and near-infrared spectroscopy, respectively.
[Results] VO2 was not significantly different between the incremental exercise
and constant exercise. However, cardiac output and muscle O2 saturation were
significantly lower for the constant exercise than the incremental exercise at the end of
exercise. [Conclusion] These findings indicate that if both tests produce a similar
VO2 value, the VO2 in incremental exercise would have a higher
ratio of cardiac output than constant exercise, and VO2 in constant exercise
would have a higher ratio of O2 extraction than incremental exercise at the end
of exercise.Key words: Cardiopulmonary exercise test, Fick equation, Near-infrared spectroscopy 相似文献

[Purpose] The purpose of the present study was to examine the effects of squat exercises
performed on different surfaces on the activity of the quadriceps femoris muscle in order
to provide information on support surfaces for effective squat exercises. [Subjects and
Method] Fourteen healthy subjects performed squat exercises for five seconds each on three
different support surfaces: hard plates, foam, and rubber air discs. Their performance was
measured using electromyography. As the subjects performed the squat exercises on each
surface, data on the activity of the vastus medialis oblique and the vastus lateralis, and
the vastus medials oblique/vastus lateralis ratio, were collected. [Results] The activity
of the vastus medialis oblique and the vastus medialis oblique/vastus lateralis ratio were
found to be statistically significantly higher on rubber air discs than when the squats
were performed on hard plates or foam. [Conclusion] To activate the vastus medialis
obilique, and to enhance the vastus medialis oblique/vastus lateralis ratio, unstable
surfaces that are highly unstable should be selected.Key words: Support surfaces, Vastus medialis obilique, Vastus lateralis 相似文献

BackgroundOptimal antiplatelet inhibition is vital during cerebrovascular stenting procedures, yet no standardized recommendation exists for antithrombotic therapy in these scenarios. Cangrelor is an intravenous P2Y12 inhibitor with a favorable pharmacokinetic profile for use during neuroendovascular stenting.MethodsA retrospective review of all neuroendovascular patients who underwent stenting between 1 January 2019 and 22 March 2020 and were treated with cangrelor was conducted. Thirty-seven patients met inclusion criteria.ResultsAll patients were administered a bolus of 5 mcg/kg of cangrelor followed by a maintenance infusion. Antiplatelet effects of cangrelor were monitored using platelet reactivity units (PRU). Based on the initial PRU, seven patients’ doses were adjusted with subsequent PRUs in or near the goal range of 50–150. One patient experienced an acute intraprocedural occlusion likely related to a subtherapeutic PRU which subsequently resolved with cangrelor dose adjustment and intra-arterial tirofiban administration, and one patient experienced a post-procedure stent occlusion which required a thrombectomy and intra-arterial tirofiban administration. No hemorrhagic complications occurred.DiscussionCangrelor utilization during neuroendovascular stenting with maintenance doses of <2 mcg/kg/min with dose adjustments based on platelet function testing has not been previously described. Cangrelor presents many advantages compared to standard therapy in patients undergoing stent placement related to its pharmacokinetic profile, rapid onset of action, ease of transition to oral P2Y12 antiplatelet agents, and measurability.ConclusionCangrelor is a promising alternative to currently available therapies, especially in patients with a high hemorrhagic risk. 相似文献

[Purpose] Lateral knee instability is frequently observed in patients with knee injury or risk factors associated with knee osteoarthritis. Physical exercises can strengthen muscles that stabilize the knee joint. The purpose of this study was to define the contribution of the knee and hip muscles to lateral knee stability by comparing the muscle forces, as assessed by musculoskeletal simulation using one or two degrees-of-freedom (1-DOF and 2-DOF) knee models. [Participants and Methods] We evaluated the normal gait of 15 healthy subjects. We conducted a three-dimensional gait analysis using a motion analysis system and a force plate. We considered a muscle as a lateral knee stabilizer when the calculated muscle force was greater with the 2-DOF model than with the 1-DOF model. [Results] During early and late stance, the muscle forces of the lateral knee and hip joint increased in the 2-DOF model as opposed to in the 1-DOF model. In contrast, the forces of the medial knee muscles decreased. Furthermore, hip muscle forces increased during the late stance. [Conclusion] Our results show that the lateral knee and hip muscles contribute to lateral knee stability. Thus, exercises to strengthen these muscles could improve lateral knee stability.Key words: Lateral knee stability, Musculoskeletal model, Gait analysis 相似文献

[Purpose] This research investigated the effect of angular variation of flexion of the
elbow joint on the muscle activation of elbow flexor muscles. [Subjects] The research
subjects were 24 male college students with a dominant right hand who had no surgical or
neurological disorders and gave their prior written consent to participation with full
knowledge of the method and purpose of this study. [Methods] The subjects'' shoulder joints
stayed in the resting position, and the elbow joint was positioned at angles of 55°, 70°,
and 90°. The angle between the pulley with weights and forearm stayed at 90°. Surface
electromyography was used to measure muscle activities. Three measurements were made at
each elbow angle, and every time the angle changed, two minutes rest was given. [Result]
The muscle activities of the elbow flexors showed significant changes with change in the
elbow joint angle, except for the biceps brachii activities between the angles of 55° and
70° of elbow flexion. The muscle activities of the biceps brachii and brachioradialis
showed angle-related changes in the order of 55°, which showed the biggest value, followed
by 70° and 90°. [Conclusion] In order to improve muscle strength of the elbow flexor using
a pulley system, it seems more effective to have a 90° angle between the pulley with
weights and the forearm when the muscle is stretched to a length 20% greater than its
resting position.Key words: Pulley with weight exercise, Joint angle, Muscle activation 相似文献

[Purpose] The purpose of this study was to evaluate whether neuromuscular joint
facilitation (NJF) training is superior to NJF distal resistance training at improving the
ROM and proprioceptive acuity of the neck. [Subjects] 10 healthy subjects (8 males, 2
females) participated in this study. [Methods] The participants were allocated to three
groups: 10 in the control group, 10 in the NJF distal resistance training group, and 10 in
the NJF training group. A miniature wireless motion recorder was used to record the
maximum cervical range of motion and joint position error (JPE) before and after the
interventions. The three interventions were tested on different days. [Results] No
difference of ROM was observed among the three groups. A significant pre- to
post-intervention decrease in JPE in extension was identified in the NJF group. No other
significant differences were observed among the three groups. [Conclusion] The NJF
training conferred remarkable benefits on the cervical JPE of healthy people. This result
suggests that the best way to improve proprioceptive acuity is intervention together with
proximal resistance training, such as NJF training.Key words: Neck, Joint position sense, Neuromuscular joint facilitation (NJF) 相似文献

[Purpose] Lumbar fusion has been used for spinal disorders when conservative treatment
fails. The minimally invasive approach causes minimal damage to the back muscles and
shortens the postoperative recovery time. However, evidence regarding functional recovery
in patients after minimally invasive lumbar spinal fusion is limited. The purpose of this
study was to investigate how trunk control ability is affected after minimally invasive
lumbar fusion surgery during the early postoperative phase. [Subjects and Methods] Sixteen
patients and 16 age- and sex-matched healthy participants were recruited. Participants
were asked to perform a maximum forward reaching task and were evaluated 1 day before and
again 1 month after the lumbar fusion surgery. Center of pressure (COP) displacement, back
muscle strength, and scores for the Visual Analog Scale, and Chinese version of the
modified Oswestry Disability Index (ODI) were recorded. [Results] The healthy control
group exhibited more favorable outcomes than the patient group both before and after
surgery in back strength, reaching distance, reaching velocity, and COP displacement. The
patient group improved significantly after surgery in all clinical outcome measurements.
However, reaching distance decreased, and the reaching velocity as well as COP
displacement did not differ before and after surgery. [Conclusion] The LBP patients with
lumbar fusion surgery showed improvement in pain intensity 1 month after surgery but no
improvement in trunk control during forward reaching. The results provide evidence that
the back muscle strength was not fully recovered in patients 1 month after surgery and
limited their ability to move their trunk forward.Key words: Biomechanics, Postural balance, Low back pain 相似文献
