[Purpose] The purpose of this study was to identify the effects of performing squat
exercises with visual feedback on the activation of the vastus medialis oblique (VMO) and
vastus lateralis (VL) muscles in young adults with an increased quadriceps angle
(Q-angle). [Subjects] This study used a motion analysis program (Dartfish, Switzerland) to
select 20 young adults with an increased Q-angle, who were then divided into a squat group
that received visual feedback (VSG, n=10) and a squat group that received no visual
feedback (SG, n=10). [Methods] The intensity of exercises was increased every two weeks
over a six-week exercise period in both groups. A visual marker was attached to the
patella of the subjects in the VSG, and they then performed squat exercises with a maximum
of 90° of knee flexion within a route marked on a mirror. The SG performed squat exercises
with a maximum 90° of knee flexion without attaching a visual feedback device. [Results]
Analysis of the muscle activation due to 90° squat exercises indicated that both groups
had statistically significant increases in activation of the VL. The VSG exhibited
statistically significant increases in activation of the VMO. [Conclusion] This study
confirmed that squat exercises with visual feedback are effective in activation of the VMO
and VL muscles. The findings are meaningful in terms of preventing the occurrence of
patellofemoral pain.Key words: Q-angle, Visual feedback squat exercise, VMO 相似文献

[Purpose] The objective of this study was to examine the effects of a training program
using the Nintendo Wii Fit Plus on the ankle muscle strengths of subjects with functional
ankle instability. [Subjects and Methods] This study was conducted using subjects in their
20s who had functional ankle instability. They were randomized to a strengthening training
group and a balance training group with 10 subjects in each, and they performed an
exercise using Nintendo Wii Fit Plus for 20 minutes. In addition, every participant
completed preparation and finishing exercises for 5 minutes, respectively. [Results] The
muscle strengths after conducting plantar flexion and dorsiflexion significantly increased
at the angular velocities of 60° and 120° in the strengthening training group.
Furthermore, the muscle strengths after conducting plantar flexion, dorsiflexion,
eversion, and inversion significantly increased at the angular velocities of 60° and 120°
in the balance training group. [Conclusion] The balance training group using Nintendo Wii
Fit Plus showed better results than the strengthening training group. Consequently, it is
recommended to add the balance training program of the Nintendo Wii Fit Plus to
conventional exercise programs to improve ankle muscle strength in functional ankle
instability at a low cost.Key words: Nintendo Wii Fit Plus, Functional ankle instability, Strength 相似文献

[Purpose] The purpose of this study was to investigate the effects of a Nintendo Wii
exercise program on chronic work-related LBP compared with stability exercise. [Methods]
Twenty-four workers participated in this study. All of the participants were diagnosed
with chronic LBP by a physician. Participants were randomly assigned to three groups: a
control group (CG), lumbar stabilization exercise group (LSE), and Nintendo Wii exercise
group (NWE). Participants were treated 3 times a week for 8 weeks. Each session lasted 30
minutes. [Results] The results demonstrated that exercise programs improved significantly
physical functions related to LBP. In health-related QOL, the Nintendo Wii exercise
program significantly improved both the mental and physical health composites, but other
groups had significant improvement only in the physical health composite. [Conclusion] The
Nintendo Wii exercise program could be a biopsychosocial intervention for work-related LBP
in factory workers.Key words: Low back pain, Exercise, Nintendo Wii 相似文献

[Purpose] The purpose of this research was to determine the effects of a virtual
reality-based yoga program on middle-aged female low back pain patients. [Subjects and
Methods] Thirty middle-aged female patients who suffered from low back pain were assigned
to either a physical therapy program or a virtual reality-based yoga program for a period
of four weeks. Participants could check their posture and weight bearing on a monitor as
they shifted their weight or changed their postures on a Wii balance board. There were a
total of seven exercise programs. A 30-minute, three times per week, virtual reality-based
Wii Fit yoga program or trunk stabilizing exercise was performed, respectively. [Results]
Repeated-measures analysis of covariance revealed significant differences in between pre-
and post-training VAS, algometer, Oswestry low-back pain disability index (ODI), Roland
Morris disability questionnaire (RMDQ), and fear avoidance beliefs questionnaire (FBQ)
scores. The VAS, algometer, ODI, RMDQ, and FBQ scores showed significant differences in
groups. Regarding the effect of time-by-group interaction, there were significant
differences in VAS, ODI, ODI, and FBQ scores. [Conclusion] In conclusion, for middle-aged
female patients who have low back pain, a virtual reality-based yoga program was shown to
have positive effects on physical improvements, and this program can be employed as a
therapeutic medium for prevention and cure of low back pain.Key words: Low back pain, Virtual reality, Yoga 相似文献

[Purpose] This study assessed the exercise capacity of healthy adults while performing the inline lunge exercise by using Functional Movement Screen (FMS). Compared the difference in muscle activity of the quadriceps according to the exercise capacity. [Participants and Methods] Thirty two healthy participants (12 males, 20 females) participated in this study. The surface electromyography (sEMG) was used to measure the electrical activities for the vastus medialis (VM), rectus femoris (RF), vastus lateralis (VL) of quadriceps. [Results] Both groups had significant difference when sitting up and getting up during the inline lunge. In scores 3 group, vastus medialis showed higher muscle activity than vastus lateralis. On contrary, in scores 2 group, vastus lateralis had higher muscle activity than vastus medialis. [Conclusion] Therefore, this study suggests that inline lunge can help to strengthen the quadriceps effectively by showing the difference of quadriceps activity according to exercise capacity.Key words: Inline lunge, Muscle activity, Functional movement screen 相似文献

Some fMRI studies in humans have located the frontal eye field (FEF) in two distinct regions along the precentral sulcus (PCS): one localized more medically, in the superior precentral sulcus (supPCR) at the junction with the superior frontal sulcus, and the other localized more laterally, along the medial part of the inferior precentral sulcus (infPCR). However, there has been no evidence of any different task activations between the regions. In the present study using fMRI, we have compared activation patterns in the regions near the PCS during saccade, fixation, and eyeblink tasks. We found that only the supPCR was activated specifically by the saccade task, while the infPCR was activated by both the saccade and eyeblink tasks. This result provides evidence that the supPCR is the human FEF homologous to the monkey FEF and that the infPCR may be homologous to the monkey premotor area. 相似文献

Purpose: To investigate the effects of visual and tactile intra-oral sensor-position feedback for target selection tasks with the tip of the tongue. Method: Target selection tasks were performed using an inductive tongue-computer interface (ITCI). Visual feedback was established by highlighting the area on a visual display corresponding to the activated intra-oral target. Tactile feedback was established using a sensor-border matrix over the sensor plates of the ITCI, which provided sensor-position tactile queues via the user’s tongue. Target selection tasks using an on-screen keyboard by controlling the mouse pointer with the ITCI’s was also evaluated. Results: Mean target selection rates of 23, 5 and 15 activations per minute were obtained using visual, tactile and “none” feedback techniques in the 3rd training session. On-screen keyboard target selection tasks averaged 10 activations per minute in the 3rd training session. Involuntary activations while speaking or drinking were significantly reduced either through a sensor-matrix or dwell time for sensor activation. Conclusions: These results provide key design considerations to further increase the typing efficiency of tongue-computer interfaces for individuals with upper-limb mobility impairments. 相似文献
Intra-oral computer interfaces could provide individuals with severe upper-limb mobility impairments the opportunity to control computers and automatic equipment.
A fast and efficient sensory feedback is vital for a good performance of an intra-oral computer interface.
Reduction of involuntary activations due to talking and drinking will improve the acceptability of intra-oral interfaces.

Lumbopelvic joint manipulation has been shown to increase quadriceps force output and activation, but the duration of effect is unknown. It is also unknown whether lower grade joint mobilisations may have a similar effect. Forty-two healthy volunteers (x+/-SD; age=28.3+/-7.3 yr; ht=172.8+/-9.8 cm; mass=76.6+/-21.7 kg) were randomly assigned to one of three groups (lumbopelvic joint manipulation, 1 min lumbar passive range of motion (PROM), or prone extension on elbows for 3 min). Quadriceps force and activation were measured using the burst-superimposition technique during a seated isometric knee extension task before and at 0, 20, 40, and 60 min following intervention. Collectively, all groups demonstrated a significant decrease (p<0.001) in quadriceps force output without changes in activation (p>0.05) at all time intervals following intervention. The group that received a lumbopelvic joint manipulation demonstrated a significant increase in quadriceps force (3%) and activation (5%) (p<0.05) immediately following intervention, but this effect was not present after the 20 min interval. Since participants in this study were free of knee joint pathology, it is possible that they did not have the capacity to allow for large changes in quadriceps muscle activation to occur. 相似文献

[Purpose] It is well known that visual feedback is an important factor contributing to
balance and postural control. Nevertheless, there has been little discussion about the
effects of visual feedback on pulmonary function. This study was conducted to investigate
the role of visual feedback on respiratory muscle activation and pulmonary function.
[Subjects and Methods] The subjects were 37 healthy adults who consented to participate in
this study. The study measured the muscular activation of the trunk and pulmonary function
according to the absence or presence of visual feedback. [Results] The results revealed
significant changes in muscular activation and pulmonary function with the use of visual
feedback. [Conclusion] These findings suggest that visual feedback may play a role in
increasing respiratory muscle activity and pulmonary function.Key words: Visual feedback, Respiratory muscles, Pulmonary function 相似文献

Scanner noise during functional magnetic resonance imaging (fMRI) may interfere with brain function and change blood oxygenation level dependent (BOLD) signals, a problem that generally worsens at the higher field strengths. Therefore, we studied the effect of increased acoustic noise on fMRI during verbal working memory (WM) processing. The sound pressure level of scanner noise was increased by 12 dBA from "Quiet" to "Loud" echo planar imaging (EPI) scans by utilizing resonant vibration modes of the gradient coil. A WM paradigm with graded levels of task difficulty was used to further access WM load. Increased scanner noise produced increased BOLD responses (percent signal change) bilaterally in the cerebellum, inferior (IFG), medial (medFG), and superior (SFG) frontal, fusiform (FusG), and the lingual (LG) gyri, and decreased BOLD responses bilaterally in the anterior cingulate gyrus (ACG) and the putamen. This finding suggests greater recruitment of attention resources in these brain regions, probably to compensate for interference due to louder scanner noise. Increased working memory load increased the BOLD signals in IFG and the cerebellum, but decreased the BOLD signals in the putamen and the LG. These findings also support the idea that brain function requires additional attention resources under noisier conditions. Load- and acoustic-noise-related changes in BOLD responses correlated negatively in the WM network. This study demonstrates that MR noise affects brain activation pattern. Future comparisons between studies performed under different acoustic conditions (due to differing magnetic field strengths, pulse sequences, or scanner manufacturers) might require knowledge of the sound pressure level of acoustic noise during fMRI. 相似文献

[Purpose] The purpose of this study was to determine the effects of activation of the
foot on the trunk mobility of patients with hemiplegia. [Subjects] Sixteen subjects with
hemiplegia took part in the immediate group (IG), and 14 subjects with hemiplegia
participated in the 2-month group (2MG). [Methods] The subjects in IG were given one leg
stance training through activation of the foot only once, and 2MG received the same
intervention for 30 minutes 3 times a week for, 8 weeks. The Spinal Mouse was used to
collect spinal alignment data. Also, the trunk Impairment Scale (TIS) and Sensory test
were used as functional tests. [Results] Sacral hip (SH), lumbar spine (LS) and thoracic
spine (TS) angles in IG improved significantly, but not inclination (I), and 2MG showed
increased angles of SH, LS and I, but not TS. Also, TIS Dynamic, TIS Coordination and
Sensory test results of 2MG increased significantly. [Conclusion] One leg stance training
through activation of the foot was effective at improving sensory input and alignment of
the spine, therefore trunk mobility was improved.Key words: Alignment, Stroke, Trunk 相似文献

[Purpose] The aim of this study was to determine the effect of resistance training on
atrophied skeletal muscle in rats based on evidence derived from physical therapy.
[Subjects and Methods] Rats were forced to undergo squats as resistance training for 3
weeks after atrophying the rectus femoris muscle by hindlimb suspension for 2 weeks. The
intensity of resistance training was adjusted to 50% and 70% of the maximum lifted weight,
i.e., 50% of the one-repetition maximum and 70% of the one-repetition maximum,
respectively. [Results] Three weeks of training did not alter the one-repetition maximum,
and muscle fibers were injured while measuring the one-repetition maximum and reloading.
The decrease in cross-sectional area in the rectus femoris muscle induced by unloading for
2 weeks was significantly recovered after training at 70% of the one-repetition maximum.
The levels of muscle RING-finger protein-1 mRNA expression were significantly lower in
muscles trained at 70% of the one-repetition maximum than in untrained muscles.
[Conclusion] These results suggest that high-intensity resistance training can promote
atrophic muscle recovery, which provides a scientific basis for therapeutic exercise
methods for treatment of atrophic muscle in physical therapy.Key words: Muscle atrophy, Quadriceps muscle, Resistance training 相似文献

Background and Purpose . To assess if lifting performance can be modified and spine stresses reduced in workers who perform repetitive material‐handling jobs in a warehouse environment via a novel real‐time, movement‐based feedback training protocol. Method . A pre‐test/post‐test group study design was used with a control group. Data were collected in a warehouse setting and analysed in a university setting. A convenience sample of 22 male warehouse employees was divided equally, based on height and weight, and assigned to either an experimental group or a control group. The experimental group received real‐time, performance‐based auditory feedback from their calculated moments during lifting or lowering using an electromagnetic tracking system. The electromagnetic tracking system was used to measure the side‐bending, flexion and rotation moments during six lifts under four different conditions. A series of repeated‐measures analyses of variance (ANOVA) (one between (Group); one within (Time)) was performed on the average maximum moments from six lifting or lowering cycles for all three directions: side‐bending, flexion and rotation. Results . There were significant group X time interactions for the side‐bending moment (p < 0.05) and the flexion moment (p < 0.05) but not the rotation moment (p > 0.05). Lower moments were found in the experimental group, which received the training and feedback, compared to the control group. Conclusions . Real‐time, auditory feedback combined with coaching during lifting or lowering tasks may be effective in the short term (six weeks) in reducing the average maximum side‐bending and flexion moments in warehouse workers. Further research is needed to determine the long‐term effects of this training protocol on low back injury rates. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

[Purpose] The aim of this study was to investigate the effects of combined application of
progressive resistance training and Russian electrical stimulation on quadriceps femoris
muscle strength in elderly women with osteoarthritis of the knee. [Subjects] Thirty women
over 65 years of age diagnosed with knee osteoarthritis participated in the present study.
The subjects were randomly assigned to a control group (n=10), a progressive resistance
training group (n=10), or a Russian electrical stimulation group (n=10). [Methods] Each
group was treated 3 times weekly for 8 weeks, and each session lasted 45 minutes. Muscle
strength was assessed by measuring the peak torque of the quadriceps femoris muscle.
Outcome measurements were performed at baseline and at the fourth and eighth weeks of the
treatment period. [Results] All groups showed significant intragroup differences in the
quadriceps femoris muscle peak torque after the treatment intervention. There were
significant intergroup differences between the Russian electrical stimulation group and
the other groups. [Conclusion] The results of this study suggest that combined application
of progressive resistance training and Russian electrical stimulation can be effective in
strengthening the quadriceps femoris muscle in elderly women with knee osteoarthritis.Key words: Knee osteoarthritis, Progressive resistance training, Russian electrical stimulation 相似文献

[Purpose] The purpose of this study was to clarify the effects of directional change on
postural adjustments during the sit-to-walk (STW) task. [Subjects] Fifteen healthy young
men participated in this study. [Methods] Subjects were required to stand up from a chair
and walk toward a target. The first step was limited to the right limb only. Three
conditions of target direction (straight, ipsilateral and contralateral) were set. For the
ipsilateral and contralateral conditions, the target was placed at an angle 45° clockwise
and 45° counterclockwise from straight ahead, respectively. Trials were recorded by a
motion capture system and force plates. The forward momentum of the body, time of events,
center of pressure (COP) and center of gravity (COG) displacement were measured and
compared between conditions. [Results] In the contralateral condition, the fluidity index
was significantly lower than that in the straight condition. In the contralateral
condition, COP displacement toward the swing limb was larger than in the other conditions.
[Conclusion] The present results indicate that a directional change during the STW task
affects fluidity and postural adjustments. When the STW direction was changed to diagonal,
the lateral component of postural control became more important.Key words: Sit-to-walk, Fluidity, Postural control 相似文献

To examine the effect of gender on regional brain activity, we utilized functional magnetic resonance imaging (fMRI) during a motor task and three cognitive tasks; a word generation task, a spatial attention task, and a working memory task in healthy male (n = 23) and female (n = 10) volunteers. Functional data were examined for group differences both in the number of pixels activated, and the blood-oxygen-level-dependent (BOLD) magnitude during each task. Males had a significantly greater mean activation than females in the working memory task with a greater number of pixels being activated in the right superior parietal gyrus and right inferior occipital gyrus, and a greater BOLD magnitude occurring in the left inferior parietal lobe. However, despite these fMRI changes, there were no significant differences between males and females on cognitive performance of the task. In contrast, in the spatial attention task, men performed better at this task than women, but there were no significant functional differences between the two groups. In the word generation task, there were no external measures of performance, but in the functional measurements, males had a significantly greater mean activation than females, where males had a significantly greater BOLD signal magnitude in the left and right dorsolateral prefrontal cortex, the right inferior parietal lobe, and the cingulate. In neither of the motor tasks (right or left hand) did males and females perform differently. Our fMRI findings during the motor tasks were a greater mean BOLD signal magnitude in males in the right hand motor task, compared to females where males had an increased BOLD signal magnitude in the right inferior parietal gyrus and in the left inferior frontal gyrus. In conclusion, these results demonstrate differential patterns of activation in males and females during a variety of cognitive tasks, even though performance in these tasks may not vary, and also that variability in performance may not be reflected in differences in brain activation. These results suggest that in functional imaging studies in clinical populations it may be sensible to examine each sex independently until this effect is more fully understood. 相似文献

[Purpose] The purpose of this study was to measure the cervical flexion-relaxation ratio
(FRR) and intensity of neck pain and identify the differences according to postures
adopted while using smartphones. [Subjects] Fifteen healthy adults with no neck pain,
spinal trauma, or history cervical surgery participated in this study. [Methods] The
activity of the cervical erector spinae muscle was recorded while performing a
standardized cervical flexion-extension movement in three phases (flexion, sustained full
flexion, extension). And neck pain intensity was recorded using a visual analog scale
(VAS) with values between 0 and 10. Postures held while using a smartphone are
distinguished between desk postures and lap postures. The FRR was calculated by dividing
the maximal muscle activation during the extension phase by average activation during the
complete flexion phase. [Results] No significant differences were found in the FRR between
desk posture, lap posture, and baseline, though the intensity of the neck pain increased
in the lap posture. [Conclusion] The FRR could be a significant criterion of neuromuscular
impairment in chronic neck pain or lumbar pain patients, but it is impossible to
distinguish neck pain that is caused by performing task for a short time. Prolonged lap
posture might cause neck pain, so the use of smartphones for a long time in this posture
should be avoided.Key words: Smartphone, Cervical flexion-relaxation ratio, Electromyography 相似文献

[Purpose] The purpose of this study was to determine the concurrent validity of Wii Fit center-of-pressure parameters with Clinical Test of Sensory Integration for Balance and to evaluate the discriminant validity of the Wii Fit center-of-pressure parameters for adults and the elderly for the assessment of postural sway. [Participants and Methods] This study used an observational cross-sectional correlational design. All 70 participants were required to complete a questionnaire for eligibility screening, followed by a center-of-pressure assessment using three Wii Fit balance activities (snowboard slalom, ski slalom, and balance bubble) and Clinical Test of Sensory Integration for Balance using a force platform. [Results] For center-of-pressure assessment, our results showed there was concurrent validity of Wii Fit ski slalom and balance bubble with Clinical Test of Sensory Integration for Balance conditions 6 and 4, respectively. Our results also demonstrated that the three Wii Fit balance activities selected in this study could be used to discriminate between adults and the elderly. [Conclusion] Our results suggest that Wii Fit is a viable and affordable alternative method for center-of-pressure assessment.Key words: Wii Fit, Centre of pressure, Validity 相似文献
