[Purpose] To investigate the relationship between isokinetic knee muscle strength and
kinematic, kinetic and spatiotemporal gait parameters of patients with multiple sclerosis
(MS). [Subjects and Methods] Twenty-nine MS patients (mean age 31.5±6.5) were investigated
in this study. The isokinetic knee muscle strength and gait parameters of MS patients with
moderate and severe disability, as determined by the expanded disability status scale
(EDSS): EDSS=1–4.5 (n=22, moderate disability) and EDSS>4.5 (n=7, severe disability)
were measured. [Results] Isokinetic knee muscle strength, kinematic, kinetic and
spatiotemporal gait parameters differed between moderate (EDSS=1–4.5, n=22) and severe
disability (EDSS>4.5, n=7). The correlation between each of gait speed, stride length,
total range of knee joint movement and the four strength parameters (minimum and maximum
quadriceps and hamstring muscle strengths) were significant for the MS group as a whole.
Within subgroups, the correlation between minimum hamstring strength and total range of
knee movement was significant only in group EDSS>4.5; minimum hamstring correlated with
peak knee extensor moment in group EDSS=1–4.5, but at a reduced level of significance.
[Conclusion] The present study revealed significant correlations between gait
characteristics and isokinetic strength parameters of the quadriceps and hamstring
muscles. Our study suggests that rehabilitation protocols for MS patients should include a
critical strength training programme particularly for the hamstring and quadriceps
muscles.Key words: Multiple sclerosis, Gait analysis, Muscle strength 相似文献

[Purpose] We evaluated the relationship between knee alignment and the electromyographic
(EMG) activity of the vastus medialis (VM) to the vastus lateralis (VL) muscles in
patients with knee osteoarthritis (OA) in a cross-sectional study. [Subjects and Methods]
Forty subjects with knee OA were assessed by anatomic radiographic knee alignment and the
VM/VL ratio was calculated. Surface EMG from both the VM and VL muscles were evaluated
during maximal isometric contraction at 60° knee flexion. Simultaneously, peak quadriceps
torque was assessed using an isokinetic dynamometer. Subjects were categorized into low,
moderate, and high varus groups according to knee malalignment. The peak quadriceps torque
and VM/VL ratio across groups, and their relationships with varus malalignment were
analyzed. [Results] All subjects had medial compartment OA and the VM/VL ratio of all
subjects was 1.31 ± 0.28 (mean ± SD). There were no significant differences in the peak
quadriceps torque or VM/VL ratios across the groups nor were there any significant
relationships with varus malalignment. [Conclusion] The VM/VL ratio and peak quadriceps
torque were not associated with the severity of knee varus malalignment.Key words: Malalignment, Knee, Quadriceps 相似文献

[Purpose] To assess the effect of hamstring and quadriceps strengthening exercises on
pain intensity, gait velocity, maximum isometric strength, and activities of daily living
of patients with knee osteoarthritis (OA). [Subjects and Methods] A total of 20 patients
with knee OA, 50 to 65 years of age (57.65 ± 4.78 years), received hot packs,
strengthening exercises for the quadriceps and the hamstring muscles and stretching
exercises for hamstring muscles. Outcome measures included: the Western Ontario and
McMaster Universities OA index questionnaire (WOMAC) scores for assessing health status
and health outcomes of knee OA; self-reported pain intensity scores, measured using a
visual analogue scale; the 50 ft walk test (a measure of gait velocity and function); and
handheld dynamometry (a tool used to measure maximum isometric strength of knee extension
and flexion). [Results] There was a significant difference between pre- and
post-intervention measures of pain intensity, 50 ft walk times, hamstring strength, and
quadriceps strength. Significant differences in WOMAC measures were also observed in the
subscales of pain, stiffness and physical function, as well as WOMAC total scores.
[Conclusion] Strengthening the hamstring muscles in addition to strengthening the
quadriceps muscles proved to be beneficial for perceived knee pain, range of motion, and
decreasing the limitation of functional performance of patients with knee OA.Key words: Hamstring/quadriceps ratio, Knee pain, Osteoarthritis 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] This study attempted to identify how genu varum or valgum affects the
electromyographic activities of the vastus medialis, vastus lateralis, and rectus femoris
during knee isometric contraction. [Subjects] Fifty-two healthy young adults were enrolled
in this study. They were enrolled and classified into three groups by knee alignment
conditions: the genu varum, genu valgum, and control groups. [Methods] The
electromyographic activity ratio of the vastus medialis to the vastus lateralis and rectus
femoris were calculated using the percentage of maximum voluntary contraction. The
participants contracted their quadriceps during isometric contraction at 30 and 60° of
knee flexion. [Results] The genu varum group had more activity in the vastus medialis than
in the vastus lateralis and rectus femoris, whereas the genu valgum group had more
activity in the vastus lateralis and rectus femoris than in the vastus medialis. There was
a significant difference in the muscle activity ratio between the vastus medialis and
vastus lateralis by angle of knee flexion degree only in the genu valgum. There were no
significant differences in any of the three groups in terms of the muscle activity ratio
of the vastus medialis to the rectus femoris by angle of knee flexion. [Conclusion] The
quadriceps femoris was used for different strategies according to knee alignment during
isometric contraction at 30 and 60°. This study suggests that rehabilitation training
programs used to strengthen the quadriceps should consider the knee alignment conditions
of the target subjects.Key words: Electromyography, Quadriceps muscle, Isometric contraction 相似文献

One of the fundamental adaptations observed with resistance training (RT) is muscle hypertrophy. Conventional and isokinetic machines provide different forms of mechanical stress, and it is possible that these two training modes could promote differing degrees of hypertrophic adaptations. There is a lack of data comparing the selective hypertrophy of the quadriceps musculature after training with a conventional knee extension machine versus an isokinetic machine. The purpose of this study was to evaluate the selective hypertrophy of the quadriceps musculature and knee extension maximal isometric torque after 14 weeks of conventional versus isokinetic RT. Thirty-five men were assigned to three groups: control group and training groups (conventional and isokinetic) performed three sets of unilateral knee extensions per session with a progressive loading scheme twice a week. Prior to and following the intervention, maximal isometric knee extensor torque was measured using an isokinetic dynamometer, and muscle thickness (MT) of quadriceps femoris muscles was assessed via ultrasound. The results indicated non-uniform changes in MT between the muscles that comprise the quadriceps femoris group. For the conventional group, significantly greater increases in rectus femoris thickness were evident versus all other quadriceps muscles (14%). For the isokinetic group, increases in RF thickness (11%) were significantly greater in comparison with the vastus intermedius only. Although the muscle thickness did not increase for all the quadriceps femoris muscles, the relative rectus femoris adaptation suggested a selective hypertrophy favouring this portion. 相似文献

[Purpose] The aim of present study was to investigate the effects of isometric
quadriceps exercise on muscle strength, pain, and function in knee osteoarthritis.
[Subjects and Methods] Outpatients (N=42, 21 per group; age range 40–65
years; 13 men and 29 women) with osteoarthritis of the knee participated in the study. The
experimental group performed isometric exercises including isometric quadriceps, straight
leg raising, and isometric hip adduction exercise 5 days a week for 5 weeks, whereas the
control group did not performed any exercise program. The outcome measures or dependent
variables selected for this study were pain intensity, isometric quadriceps strength, and
knee function. These variables were measured using the Numerical Rating Scale (NRS),
strength gauge device, and reduced WOMAC index, respectively. All the measurements were
taken at baseline (week 0) and at the end of the trial at week 5. [Results] In
between-group comparisons, the maximum isometric quadriceps strength, reduction in pain
intensity, and improvement in function in the isometric exercise group at the end of the
5th week were significantly greater than those of the control group (p<0.05).
[Conclusion] The 5-week isometric quadriceps exercise program showed beneficial effects on
quadriceps muscle strength, pain, and functional disability in patients with
osteoarthritis of the knee.Key words: Isometric exercise, Osteoarthritis, Rehabilitation 相似文献

[Purpose] Little is known about the outcome differences between men and women after
anterior cruciate ligament (ACL) reconstruction. Therefore, the present study aimed to
compare knee muscle strength between men and women 1 year after ACL reconstruction.
[Subjects and Methods] Retrospective and outcome study. Between 2012 and 2015, 35 males
(mean age, 29.7 ± 010.7 years) and 35 females (mean age, 28.2 ± 11.3 years) who had
undergone primary ACL reconstruction were recruited from Samsung medical centers. We
assessed the strength deficit in the quadriceps (extensor) and hamstrings (flexor) at
60°/sec and 180°/sec with isokinetic testing equipment. Statistical analysis was conducted
with a t-test to determine if sex differences existed in knee strength
deficit. [Results] Significant differences were noted between men and women with respect
to extensor muscle strength deficit. Women reported less extensor muscle strength than men
did, at the angular velocities 60°/sec and 180°/sec. However, no significant sex
differences were found at either velocity with respect to the strength deficit of the knee
flexor muscles. [Conclusion] Compared to male patients, female patients reported
significantly less extensor muscle strength and less improvement 1 year after
reconstruction.Key words: Anterior cruciate ligament, Sex, Female 相似文献

[Purpose] To observe the effect of daily standing, as indicated by gross motor function, on the quantity and quality of the thigh muscles in adults with severe cerebral palsy and to obtain data to determine an appropriate intervention that will improve their quality of life. [Participants and Methods] Thirty-three adults with severe cerebral palsy participated in the study. We assessed the gross motor function using the GMFM-66-IS. We then evaluated the quadriceps muscle thickness and the rectus femoris muscle echo intensity using ultrasonography. We divided the participants into the standing and non-standing groups and then examined the correlations of the GMFM-66-IS score to muscle thickness and echo intensity. We calculated the difference in mean muscle thickness and echo intensity between the two groups using an independent t-test. [Results] Significant positive correlations were found between the GMFM-66-IS score and muscle thickness and echo intensity. In the group-specific analysis, no significant correlation was found between echo intensity and the GMFM-66-IS score in either group. Muscle thickness and echo intensity were greater in the participants of the standing group. [Conclusion] Daily standing, as indicated by gross motor function, affected muscle thickness and echo intensity. Quantitative and qualitative data might need to be evaluated when assessing the muscles of adults with severe cerebral palsy using ultrasonography.Key words: Severe cerebral palsy, Standing in daily activities, Changing muscle quality 相似文献

[Purpose] To examine changes in the knee joint’s isokinetic muscle functions following
systematic and gradual rehabilitation exercises lasting for 12 weeks for male and female
patients who underwent anterior cruciate ligament (ACL) reconstruction. Differences in
muscle functions between the uninvolved side (US) and the involved side (IS) before
surgery, differences in muscle functions between US and IS after rehabilitation exercises
lasting for 12 weeks, and changes in muscle functions on US and IS between before and
after surgery were analyzed to examine the effects of accelerated rehabilitation exercises
after ACL reconstruction. [Subjects] The study subjects were 10 patients, five females and
five males, who underwent ACL reconstruction performed by the same surgeon. [Methods] As a
measuring tool, a Biodex Multi-joint system 3pro (USA), which is an isokinetic measuring
device, was used to examine the flexion and extension forces of the knee joint. During
isokinetic muscle strength evaluation, the ROM of US was set to be the same as that of IS
for consistency of measurement. [Results] At 60°/s, the isokinetic muscle functions of the
females did not show any significant change between before and after surgery in any of the
variables on both US and IS. At 60°/s, the isokinetic muscle functions of the males did
not show any significant change between before and after surgery in the peak torque,
average power, and entire work done on US. In extension, peak torque on IS did not show
any significant change.Key words: Anterior cruciate ligament, Isokinetic, Rehabilitation 相似文献

[Purpose] The purpose of this study was to conduct a scientific analysis of the
effectiveness of Kinesio taping at preventing injury and improving horse racing jockey''
performance, by studying the effects on isokinetic muscular function of Kinesio taping
applied to the knee joint muscle. [Subjects] Eight horse racing jockeys were selected for
this study. [Methods] Measurement of isokinetic muscular function of both flexor and
extensor muscles was performed at the angular velocities of 60°/sec and 180°/sec using a
Biodex system 3, before and after application of Kinesio taping to the rectus femoris,
vastus medialis, vastus lateralis, and hamstring. [Result] At the angular velocities of
60°/sec and 180°/sec, significant differences were observed in both flexor and extensor
peak torque, average power, and total work of the knee joint after application of Kinesio
taping. [Conclusion] The application of Kinesio taping has a positive effect on the
function of both knee flexors and extensors, and also kinetic ability. Therefore, its use
would lead to a significant increase in the muscle function of horse racing jockeys.Key words: Horse racing jockeys, Isokinetic, Kinesio taping 相似文献

[Purpose] The purpose of this study was to investigate the difference in onset timing
between the vastus medialis and lateralis among the different knee alignments, as well as
the best isokinetic angular velocity for an isokinetic concentric contraction. [Subjects]
Fifty-two adults (20 with genu varum, 12 genu valgum, and 20 controls) were enrolled in
this study. Subjects with > 4 cm between the medial epicondyles of the knee were placed
in the genu varum group, whereas subjects with > 4 cm between the medial malleolus of
the ankle were placed in the genu valgum group. [Methods] Surface electromyography was
used to measure the onset times of the vastus medialis and vastus lateralis during
concentric contractions at 30, 60, and 90°/sec. [Results] The vastus lateralis showed more
delayed firing than the vastus medialis in the genu varum group, whereas vastus medialis
firing was delayed more than that of the vastus lateralis in the genu valgum group. No
differences in onset timing were observed between the vastus medialis and lateralis
according the different angular velocities during concentric contractions in all three
groups. [Conclusion] Genu varum and valgum affect quadriceps firing. Therefore, selective
rehabilitation training of the quadriceps femoris should be considered to prevent pain or
knee malalignment deformities.Key words: Quadriceps muscle, Genu varum, Genu valgum 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

[Purpose] This investigation evaluated the effect of real-time feedback on electrical
activation of the quadriceps during 3 weight-bearing tasks of the Wii Fit
Plus®. [Subjects] Thirty male healthy volunteers were recruited. [Methods]
Activation of the vastus medialis, vastus lateralis, and rectus femoris muscles was
recorded during virtual lunge, single leg extension, and single leg reach exercises. Each
exercise was performed twice in 3 randomized experimental conditions (with visual
feedback, with auditory feedback, and with no feedback). The normalized electromyographic
data (using maximum voluntary isometric contraction) were analyzed using repeated measures
analysis of variance and Tukey’s test. [Results] No significant difference was found in
the muscles among the feedback conditions during the 3 exercises. However, the variation
in the muscle activity of the vastus medialis and vastus lateralis (18.23–29.20% of
maximum voluntary isometric contraction) was higher (47–62%) than that in the rectus
femoris (7.35–12.98% of maximum voluntary isometric contraction). [Conclusion] Real-time
feedback did not alter quadriceps activation during the Wii tasks. Additionally, these
games showed electromyographic activation levels similar to those for the same tasks
outside the virtual environment. The Wii weight-bearing tasks could therefore constitute a
physical activity program but without the additional benefit of feedback.Key words: Electromyography, Functional exercises, Exergames 相似文献

[Purpose] This study compared the electromyographic activity of the quadriceps in
hemiplegic patients during the downward, maintenance, and upward phases of squat exercises
performed with the feet parallel and with the non-paretic foot lifted. [Subjects] A total
of 17 hemiplegic patients (9 males and 8 females) volunteered for this study. [Methods]
All subjects performed squat exercises with the knees flexed to 30° and with the feet
parallel (shoulder-width apart) or with lifting of the non-paretic foot (normalized to 25%
of the knee height). [Results] The activity of the rectus femoris, vastus medialis
oblique, and vastus lateralis muscles was significantly higher during squat exercises
performed with the non-paretic foot lifted than with the feet parallel to each other. The
activity of all muscles during the maintenance phase of the exercises was greater than
that during the downward and upward phases. [Conclusion] Lifting the non-paretic foot
during squats may represent an effective exercise for motor function rehabilitation in
hemiplegic patients.Key words: EMG, Foot lifting, Squat exercise 相似文献

[Purpose] The purpose of this study was to clarify the influence of static stretching at
warm-up on the isokinetic muscle torque (at 60°/sec) and muscle power (at 180°/sec) of the
flexor muscle and extensor muscle of the knee joint. [Subjects and Methods] The subjects
of this study were 10 healthy students with no medically specific findings. The warm-up
group and warm-up with stretching group performed their respective warm-up prior to the
isokinetic muscle torque evaluation of the knee joint. One-way ANOVA was performed by
randomized block design for each variable. [Results] The results were as follows: First,
the flexor peak torque and extensor peak torque of the knee joint tended to decrease at
60°/sec in the warm-up with stretching group compared with the control group and warm-up
group, but without statistical significance. Second, extensor power at 180°/sec was also
not statistically significant. However, it was found that flexor power increased
significantly in the warm-up with stretching group at 180°/sec compared with the control
group and warm-up group in which stretching was not performed. [Conclusion] Therefore, it
is considered that in healthy adults, warm-up including two sets of stretching for 20
seconds per muscle group does not decrease muscle strength and muscle power.Key words: Stretching, Warm-up, Muscle power 相似文献

[Purpose] This study aimed to examine the effects of muscle fatigue on skin sensation by
looking at changes in two-point discrimination (2PD) after inducing muscle fatigue.
[Subjects] Thirty-four young and healthy adults with no pathological symptoms (17 males;
17 females) participated in this study. [Methods] Continuous isometric contraction was
applied to the upper and lower extremities with an intensity of 50% of the maximal muscle
strength to trigger muscle fatigue, and then the 2PD test was conducted on the 3 cm medial
area of the elbow and 5 cm area of the knee bone. [Results] After muscle fatigue was
induced, the 2PD distance significantly increased in the upper and lower extremities of
both males and females. Before triggering muscle fatigue, the 2PD distance was longer in
males than females, but after causing muscle fatigue, there was no difference between
males and females. The increase in 2PD distance after the experiment was more significant
in females than males. [Conclusion] Muscle fatigue has an effect of reducing the skin’s
sensory faculty by increasing the 2PD distance in the skin. There is a difference in the
response of the skin according to body area and gender; therefore, caution is needed to
avoid triggering fatigue during exercise.Key words: Muscle fatigue, Skin sensation, Two-point discrimination 相似文献

[Purpose] The purpose of this study was to examine the effects of closed kinetic chain
exercises (CKCEs) and open kinetic chain exercises (OKCEs) with elastic bands on the
electromyographic activity of patients with degenerative gonarthritis. [Subjects] The
study subjects were 30 degenerative gonarthritis patients who were divided into a CKCE
group (CKCEG, n=10), an OKCE group (OKCEG, n=10), and a control group (CG, n=10).
[Methods] The CKCEG and the OKCEG performed exercises with elastic bands, and the CG took
part in a quadriceps strengthening exercise. All three groups performed the exercises
three times per week for four weeks. The electromyographic activities of the subjects’
vastus medialis (VM), rectus femoris (RF), vastus lateralis (VL), semitendinosus (ST), and
biceps femoris (BF) muscles were measured and compared. [Results] Within-group comparisons
revealed that the electromyographic activities of the VM, RF, VL, ST, and BF muscles
increased significantly in the CKCEG. The OKCEG displayed significant increases in the
electromyographic activity of the VM, RF, ST, and BF muscles, and the CG showed
significant increases in the electromyographic activities of the RF, VL, ST, and BF
muscles. In between-group comparisons after the intervention, the electromyographic
activities of the VM, RF, and VL muscles of the CKCEG were significantly higher than those
of the CG. The electromyographic activities of the VM, RF, and ST muscles of the OKCEG
were significantly higher than those of the CG. [Conclusion] We consider CKCEs with
elastic bands are an effective intervention for increasing the electromyographic
activities of the VM, RF, VL, ST, and BF muscles of degenerative gonarthritis patients,
and OKCEs with elastic bands are an effective intervention for increasing the
electromyographic activities of the VM, RF, ST, and BF muscles of degenerative
gonarthritis patients. 相似文献

[Purpose] This study investigated the change in hip muscle strength of younger persons
after neuromuscular joint facilitation (NJF) treatment. [Subjects] The subjects were 45
healthy young people, who were divided into two groups: a NJF group and a proprioceptive
neuromuscular facilitation (PNF) group. The NJF group consisted of 21 subjects (11 males,
10 females), and the PNF group consisted of 24 subjects (11 males, 13 females). [Methods]
Participants in the NJF group received NJF treatment. We measured the maximal flexor
strength and the maximal extensor strength during isokinetic movement of the hip joint
before and after intervention in both groups. The angular velocities used were 60°/sec and
180°/sec. [Results] The NJF group showed significant increases in the maximal flexor
strength and the maximal extensor strength after the intervention at each angular
velocity. In the PNF group, the maximal flexor strength of 60°/sec and the maximal
extensor strength of 180°/sec were significant increases. [Conclusion] These results
suggest that there is an immediate effect of NJF intervention on hip muscle strength.Key words: Neuromuscular joint facilitation, Hip muscle strength 相似文献
