[Purpose] We examined the inter-rater reliability of the Wright respirometer between therapists who assessed the vital capacity of patients with neuromuscular disorders. [Participants and Methods] We examined 18 patients with neuromuscular disorders. We performed a test-retest method after measuring their vital capacities. Two physical therapists experienced in the use of the Wright respirometer, specifically, therapist A with six years of clinical experience and therapist B with one, each took one measurement of the vital capacity of the same patients. The measurements between the therapists were taken at intervals of 3–7 days. We made a manual to standardize the measurements between the therapists. [Results] The vital capacities were 905 ± 490 mL for therapist A and 897 ± 483 mL for therapist B. The inter-rater reliability of ICC2,1 was 0.96 (95% CI: 0.89–0.98). Bland-Altman analyses revealed neither a fixed nor proportional bias. [Conclusion] These results demonstrated good to excellent inter-rater reliability of the Wright respirometer for patients with neuromuscular disorders using a manual and instructions. 相似文献

[Purpose] The purpose of this study was to investigate the concurrent validity and
test-retest reliability of the recently introduced OPTOGait Photoelectric Cell System for
the assessment of spatio-temporal parameters of gait. [Subjects] Twenty healthy young
adults (mean age = 27.35, SD = 7.4) were asked to walk 3 times on walkway at a comfortable
speed. [Methods] Concurrent validity was assessed by comparing data obtained using the
OPTOGait and GAITRite systems, and reliability was assessed by comparing data from the
first and third OPTOGait sessions. [Results] Concurrent validity, as identified by
intra-class correlation coefficients (ICC (2, 1) = 0.929–0.998), coefficients of variation
(CVME = 0.32–11.30%), and 95% limits of agreement, showed high levels of
correlation. In addition, the test-retest reliability of the OPTOGait Photoelectric Cell
System was demonstrated as showing a high level of correlation with all spatio-temporal
parameters by intra-class correlation coefficients (ICC (3, 1) = 0.785–0.952),
coefficients of variation (CVME = 1.66–4.06%), 95% limits of agreement,
standard error of measurement (SEM = 2.17–5.96%), and minimum detectable change
(MDC95% = 6.01–16.52%). [Conclusion] The OPTOGait Photoelectric Cell System
has strong concurrent validity along with relative and absolute test-retest reliabilities.
This portable system with easy-to-use features can be used for clinical assessments or
research purposes as an objective means of assessing gait.Key words: Locomotion, Measurement, Analysis 相似文献

[Purpose] Physical therapists, osteopathic practitioners, and chiropractors often perform
manual tests to evaluate sacroiliac joint (SIJ) mobility. However, the available evidence
demonstrates an absence of reliability in these tests and in investigations with kinematic
analysis. The aim of this study was to verify the three-dimensional kinematic reliability
in SIJ movement measurements. [Subjects] This cross-sectional study analyzed 24 healthy
males, aged between 18 and 35 years. [Methods] Three-dimensional kinematic analysis was
performed for measurements of posterior superior iliac displacement and greater trochanter
(femur) displacement during hip flexion movement in an orthostatic position. The distance
variations were measured from a reference point in 3 blocks. The intra-observer
reliability was compared with the mean of three 3 blocks using the interclass correlation
coefficient (ICC) and a 99% significance level. [Results] The measurements indicated a
strong correlation among blocks: ICC = 0.94 for right side SIJ and ICC = 0.91 for left
side SIJ. The mean displacement between the reference points was 7.7 mm on the right side
and 8.5 mm on the left side. [Conclusion] Our results indicate that three-dimensional
kinematic analysis can be used for SIJ mobility analyses. New studies should be performed
for subjects with SIJ dysfunction to verify the effectiveness of this method.Key words: Sacroiliac joint, Reliability, Three-dimensional kinematic 相似文献

[Purpose] The aim of this study was to determine the inter-rater and intra-rater
reliability of the mandibular range of motion (ROM) considering the neutral craniocervical
position when performing the measurements. [Subjects and Methods] The sample consisted of
50 asymptomatic subjects. Two raters measured four mandibular ROMs (maximal mouth opening
(MMO), laterals, and protrusion) using the craniomandibular scale. Subjects alternated
between raters, receiving two complete trials per day, two days apart. Intra- and
inter-rater reliability was determined using intra-class correlation coefficients (ICCs).
Bland-Altman analysis was used to assess reliability, bias, and variability. Finally, the
standard error of measurement (SEM) and minimal detectable change (MDC) were analyzed to
measure responsiveness. [Results] Reliability was good for MMO (inter-rater, ICC=
0.95−0.96; intra-rater, ICC= 0.95−0.96) and for protrusion (inter-rater, ICC= 0.92−0.94;
intra-rater, ICC= 0.93−0.96). Reliability was moderate for lateral excursions. The MMO and
protrusion SEM ranged from 0.74 to 0.82 mm and from 0.29 to 0.49 mm, while the MDCs ranged
from 1.73 to 1.91 mm and from 0.69 to 0.14 mm respectively. The analysis showed no random
or systematic error, suggesting that effect learning did not affect reliability.
[Conclusion] A standardized protocol for assessment of mandibular ROM in a neutral
craniocervical position obtained good inter- and intra-rater reliability for MMO and
protrusion and moderate inter- and intra-rater reliability for lateral excursions.Key words: Reliability, Range of motion, Temporomandibular joint 相似文献

[Purpose] The purpose of this study was to examine test-retest reliability of the Good
Balance system® for measurement of postural sway in poststroke
patients. [Subjects] Sixty chronic stroke patients (40 men and 20 women; age 63.08 years;
stroke duration 16.45 months) participated in this study. [Methods] Postural sway was
evaluated using a force platform system (Good Balance system, Metitur Oy, Jyvaskyla,
Finland). Two examiners measured postural sway for all participants during two separate
testing sessions. The second measurement was performed one week after the first
measurement. Intraclass correlation coefficients [ICC(2,1)] were used for
estimation of reliability. [Results] The ICC (95% CI) for intra-examiner reliability was
good to very good, ranging from 0.69 to 0.93 (0.53–0.96), and the ICC for inter-examiner
reliability was good to very good, ranging from 0.85 to 0.98 (0.77–0.99). [Conclusion] The
results of the current study indicated that the intra- and inter-examiner reliability of
the Good Balance system® for measurement of postural sway was good
to very good. Therefore, we suggest that measurement of postural sway using the Good
Balance system® would be useful for clinical assessment in
poststroke patients.Key words: Postural sway, Reliability, Stroke 相似文献

[Purpose] The purpose of this study was to examine the reliability of three isometric
knee extension strength measurements (IKE) made with a hand-held dynamometer (HHD) and a
belt of healthy elderly living in the community as subjects. [Subjects] The subject cohort
consisted of 186 healthy elderly people, aged 65 to 79 years, living in local communities.
[Methods] IKE of the leg subjects used to kick a ball was measured. IKE of each subject
was measured three times using an HHD-belt at intervals of 30 seconds. The reliability of
the larger of the first two measurements (LV2) as well as the third measurement (3V) was
investigated. [Results] The intraclass correlation coefficients [ICC (1, 1)] for LV2 and
3V were 0.955. Bland-Altman analysis showed a fixed bias, and the limits of agreement
ranged from −5.6 to 4.6. [Conclusion] The ICC results show that the test-retest
reproducibility of IKE measurements of healthy elderly subjects using an HHD-belt is high.
However, Bland-Altman analysis showed a fixed bias, suggesting the need for three
measurements.Key words: Hand-held dynamometer, Healthy elderly subjects, Knee extension muscle strength 相似文献

[Purpose] Postural problems of adolescents needs to be evaluated accurately because they
may lead to greater problems in the musculoskeletal system as they develop. Although
photographic posture analysis has been frequently used, more simple and accessible methods
are still needed. The purpose of this study was to investigate the inter- and intra-rater
reliability of photographic posture analysis using MB-ruler software. [Subjects and
Methods] Subjects were 30 adolescents (15 girls and 15 boys, mean age: 16.4±0.4 years,
mean height 166.3±6.7 cm, mean weight 63.8±15.1 kg) and photographs of their habitual
standing posture photographs were taken in the sagittal plane. For the evaluation of
postural angles, reflective markers were placed on anatomical landmarks. For angular
measurements, MB-ruler (Markus Bader- MB Software Solutions, triangular screen ruler) was
used. Photographic evaluations were performed by two observers with a repetition after a
week. Test-retest and inter-rater reliability evaluations were calculated using
intra-class correlation coefficients (ICC). [Results] Inter-rater (ICC>0.972) and
test-retest (ICC>0.774) reliability were found to be in the range of acceptable to
excellent. [Conclusion] Reference angles for postural evaluation were found to be reliable
and repeatable. The present method was found to be an easy and non-invasive method and it
may be utilized by researchers who are in search of an alternative method for photographic
postural assessments.Key words: Adolescents, Posture assessment, Reliability 相似文献

[Purpose] This study aimed to clarify the required number of measurements to calculate trunk muscle thickness at each position. [Participants and Methods] The participants were 30 elderly males aged >65 years. The right lumbar multifidus (L2), lumbar multifidus (L5), erector spinae, transversus abdominis, internal oblique, and external oblique muscle thicknesses were measured on longitudinal images obtained using ultrasonography in the lying, sitting, and standing positions. Two measurement values for each muscle thickness was used to calculate the intraclass correlation coefficient (1.1–1.5). [Results] The intraclass correlation coefficients of the abdominal muscle thickness measurements with “great reliabilities” were as follows: 1.3–1.5 for the external oblique muscle and 1.2–1.5 for the internal oblique and transversus abdominis muscles in the lying position; 1.3–1.5 for the external oblique and transversus abdominis muscles and 1.2–1.5 for the internal oblique muscle in the sitting position; the intraclass correlation coefficient in the standing position was 1.5 for the external oblique muscle 1.1–1.5 for the internal oblique muscle and 1.3–1.5 for the transversus abdominis muscle. In all the positions, the intraclass correlation coefficient of the measurements of the back-muscle thicknesses ranged from 1.1 to 1.5 for the right lumbar multifidus (L2), lumbar multifidus (L5), and erector spinae. [Conclusion] Depending on the posture, the abdominal muscles require multiple measurements, whereas the back muscles only require a single measurement.Key words: Intraclass correlation coefficient, Trunk muscle thicknesses, Ultrasonography 相似文献

[Purpose] The thickness of the perimuscular connective tissue (PMCT) reflects muscular atrophy and decreased flexibility that may cause low back pain. However, few studies have used ultrasound imaging to measure PMCT thickness. We aimed to examine and confirm the reliability of ultrasound in measuring the thickness of the PMCT of the abdominal wall muscle. [Participants and Methods] The participants were 38 healthy adult males without chronic back pain. The images were acquired in B mode with the participants in the supine position and the PMCT thickness of the abdominal wall muscle was measured on the images. The intraclass correlation coefficient (ICC) was used to confirm reliability. [Results] The ICC for both within-day and between-day PMCT measurements by ultrasound were 0.7–0.9. The 95% confidence interval ranged from 0.5–0.9. The standard error of measurement (SEM) was 0.02–0.1 mm in the abdominal wall muscle and 0.5 mm in the interrecti distance (IRD). The 95% confidence interval (95% CI) of the minimum detectable change (MDC95) was 0.1–0.3 mm in the abdominal wall muscle and 1.3–1.4 mm in the IRD. [Conclusion] We conducted a study to confirm the reliability of ultrasound-based measurement of PMCT thickness of the abdominal wall muscle, and the ICC results established reliability. However, since the values measured were small (0.02–1.4 mm) and there is a limit to visual observation, it was necessary to measure using computer software.Key words: Ultrasound measurement, Perimuscular connective tissue, Reliability 相似文献

[Purpose] The aim of this study was to examine the test-retest reliability of pinch
strength testing in elderly subjects with thumb CMC OA. [Subjects and Methods] A total of
27 patients with unilateral right-thumb CMC OA (mean ± SD age: 81.3 ± 4.7 years) were
recruited. Each patient performed three pain-free maximal isometric contractions on each
hand on two occasions, one week apart. Three different measurements were taken: tip,
tripod, and key pinch strength. Intraclass correlation coefficient (ICC), standard error
of measurement (SEM), and 95% limits of agreement (LOA) calculations were performed.
[Results] Test-retest reliability of measurements of tip, tripod, and key pinch strength
was excellent for the affected side (ICC=0.93, 0.96, and 0.99) and the contralateral thumb
(ICC=0.91, 0.92, and 0.94). [Conclusions] The present results indicate that maximum pinch
strength can be measured reliably using the Pinch Gauge Dynamometer, in patients with
thumb CMC OA, which enables its use in research and in the clinic to determine the effect
of interventions on improving pinch strength.Key words: Test-retest, Reliability, Pinch strength 相似文献

[Purpose] To investigate the intra- and inter-rater reliability of the cross-sectional
area (CSA) and muscle thickness (MT) of the longus colli according to the inward pressure
of an ultrasonography (US) probe (0.5 and 1 kg). [Subjects] Thirteen subjects (11 males
and 2 females; age, 23.1 ± 2.9 years) were recruited via convenience sampling of
university students. [Methods] Real-time US measurements of the CSA and MT of the longus
colli were recorded. Repeated US measurements using a standard protocol were performed on
the same day 1 hour apart to assess intra- and inter-rater reliability. Intra-class
correlation coefficients (ICC; 2, 1) were used to determine the intra- and inter-rater
reliability of the CSA and MT measurements. [Results] This study demonstrated that the US
measurements (0.5 and 1 kg) of the CSA and MT of the longus colli give reliable and
consistent results. [Conclusion] Based on these results, a consistent inward pressure of
the probe is needed to ensure precise US measurement of the longus colli muscle.Key words: Inward pressure, Longus colli, Ultrasound 相似文献

BackgroundCurrent clinical screening tools assessing risky movements during cutting maneuvers do not adequately address sagittal plane foot and ankle evaluations. The Cutting Alignment Scoring Tool (CAST) is reliable in evaluating frontal plane trunk and lower extremity alignment during a 45-degree side-step cut. The Expanded Cutting Alignment Scoring Tool (E-CAST) includes two new sagittal plane variables, knee flexion and ankle plantarflexion angle.Hypothesis/PurposeTo assess the inter-and intra-rater reliability of the E-CAST to evaluate trunk and lower extremity alignment during a 45-degree side-step cut.Study DesignRepeated MeasuresMethodsParticipants included 25 healthy females (13.8 ± 1.4 years) regularly participating in cutting or pivoting sports. Participants were recorded performing a side-step cut in frontal and sagittal planes. One trial was randomly selected for analysis. Two physical therapists independently scored each video using the E-CAST on two separate occasions, with randomization and a two-week wash-out between rounds. Observed movement variables were awarded a score of “1”, with higher scores representing poorer technique. Intraclass correlation coefficients (ICC) and 95% confident intervals (95% CI) were calculated for the total score, and a kappa coefficient (k) was calculated for each variable.ResultsThe cumulative intra-rater reliability was good (ICC=0.78, 95% CI 0.59-0.96) and the cumulative inter-rater reliability was moderate (ICC=0.71, 95% CI 0.50-0.91). Intra-rater kappa coefficients ranged from moderate to excellent for all variables (k= 0.50-0.84) and inter-rater kappa coefficients ranged from slight to excellent for all variables (k=0.20-0.90).ConclusionThe addition of two sagittal plane variables resulted in lower inter-rater ICC compared to the CAST (ICC= 0.81, 95% CI 0.64-0.91). The E-CAST is a reliable tool to evaluate trunk and LE alignment during a 45-degree side-step cut, with good intra-rater and moderate inter-rater reliability.Level of EvidenceLevel 2, Diagnosis 相似文献

[Purpose] The aim of this study was to translate the Pregnancy Physical Activity
Questionnaire into Turkish and test its reliability and validity among Turkish pregnant
women. [Subjects and Methods] The subjects were 204 healthy, single pregnant women between
the ages 18 and 40 who volunteered to participate in this study. Reliability was evaluated
by measuring the one-week test-retest reliability with the intraclass correlation
coefficient and Pearson’s correlation analysis. Concurrent validity was examined by
comparing the Pregnancy Physical Activity Questionnaire with the long form of the
International Physical Activity Questionnaire and step counts with pedometer. [Results]
The mean age of the participants was 28.23±4.94 years, and the mean for BMI was
26.09±4.40. For test-retest reliability, r values were respectively 0.961, 0.934, 0.957
and 0.981 for self-reported sedentary, light, moderate, and vigorous activity,
respectively. Intraclass correlation coefficient scores ranged from 0.924 to 0.993. For
validity, the Pearson’s correlation coefficients between the Pregnancy Physical Activity
Questionnaire and long form of the International Physical Activity Questionnaire ranged
from moderate (r = 0.329) to high (r = 0.672). The correlation value between the total
score of the Pregnancy Physical Activity Questionnaire and the step counts was 0.70.
[Conclusion] The Turkish version of the Pregnancy Physical Activity Questionnaire is a
valid and reliable tool for measurement of the physical activity level of pregnant
women.Key words: Pregnancy, Physical activity questionnaire, Reliability 相似文献

[Purpose] This study investigated the intra-rater, inter-rater and test-retest
reliability of the sideways step test (SST), its correlation with other indicators of
stroke-specific impairment, and the cut-off count best discriminating subjects with stroke
from their healthy counterparts. [Subjects and Methods] Forty-three subjects with chronic
stroke and 41 healthy subjects older than 50 years participated in this study. The SST was
administered along with the Fugl-Meyer motor assessment for the lower extremities
(FMA-LE), the five-times sit to stand (5TSTS) test, the Berg Balance Scale (BBS), the
movement velocity (MVL) by the limits of stability (LOS) test, the ten-metre walk (10mW)
test, the timed “Up and Go” (TUG) test and the Activities-specific Balance Confidence
(ABC) scale. [Results] The SST showed good to excellent intra-rater, inter-rater and
test-retest reliability. The SST counts correlated with 5TSTS times, 10mW times, TUG
times, and the FMA-LE and BBS scores. SST counts of 11 for the paretic leg and 14 for the
non-paretic leg were found to distinguish the healthy adults from subjects with stroke.
[Conclusion] The sideways step test is a reliable clinical test, which correlates with the
functional strength, gait speed, and functional balance of people with chronic stroke.Key words: Balance, Stroke, Rehabilitation 相似文献

[Purpose] This study aimed to investigate the reliability of time constant measurements of oxygen intake at fast and comfortable speeds during a 6-min waling test. [Participants and Methods] The study included 10 healthy young males who walked at 4.5 km/h and 6.0 km/h twice for 6 min each in speed treadmill. Breath-by-breath gas exchange data were continuously measured and used to calculate the time constant of oxygen uptake. The reproducibility and variability of the variables were verified using the limit of agreement, inter-class correlation coefficient, coefficient of variation, and standard error of measurement. [Results] The limit of agreement was −8.5 to 2.3 s and −3.9 to 2.1 s for speeds 4.5 km/h and 6.0 km/h, respectively. The inter-class correlation coefficient, coefficient of variation, and standard error of measurement of the time constant for both speeds were 0.52 and 0.83, 11.2% and 6.4%, and 5.3 s and 1.8 s, respectively. [Conclusion] The results of this study suggested that the cardiopulmonary response, in terms of oxygen uptake, was more consistent during fast walking than during comfortable walking in a 6-min walking test with constant speed. 相似文献

[Purpose] The aim of this study was to examine the applicability of the Objective
Structured Clinical Examination (OSCE) to postgraduate education systems for novice and
mid-career therapists in workplaces. [Subjects] Physical and occupational therapists with
1 to 5 years of clinical experience took the OSCE to assess their learning, with a
physical or occupational therapy faculty member and a clinical supervisor as examiners.
Another clinical supervisor acted as a simulated patient. [Methods] A Wilcoxon signed-rank
test was performed to compare skills between before and after OSCE-based learning, and a
Mann-Whitney U test was used to compare them between therapists with 1 to 2 years (novice)
and 3 to 5 years (mid-career) of clinical experience. [Results] While no
experience-related differences were observed in behavioral aspects, mid-career therapists
exhibited markedly higher scores compared with novices in technical aspects, such as
skills to guide patients for standing up, transfer, and dressing. [Conclusion] The OSCE
may be sufficiently applicable to postgraduate education systems in workplaces.Key words: OSCE, Clinical skill, Physical and occupational therapists 相似文献

[Purpose] To assess the agreement between our custom Bluetooth IS system and the gold standard MOCAP system during gait. Bluetooth inertial movement sensors (IS) allow for real-time movement analysis with fewer restrictions than optoelectrical motion capture systems (MOCAP) and more accessibility than wireless IS systems. [Participants and Methods] We collected simultaneous Bluetooth IS and MOCAP data for 16 young participants walking at a self-selected speed. Sensors were placed on the right thigh and shank. Segment angles and stride length were calculated and compared between systems using Pearson’s correlation coefficients (R), intra-class correlation coefficients (ICC), root mean square errors (RMSE), limits of agreement (LOA), and Bland-Altman plots. [Results] R values ranged from 0.371–0.715; ICC values ranged from 0.263–0.770. RMSE was 0.369 m for stride length and ranged from 6.85–13.07° in segment angles. Limits of agreement were −0.01–0.66 m for stride length and ranged from −27.71–20.53° in segment angles. [Conclusion] The Bluetooth IS system showed moderate agreement with MOCAP. Bluetooth IS could be used for reliable gait analysis with fewer space requirements and more portability than wireless IS or MOCAP systems. Bluetooth IS could be used outside of the clinic for real-time monitoring of gait during daily life. 相似文献

[Purpose] The purpose of this study was to examine the test-retest reliability and minimal detectable change (MDC) of reach distance and movement angle analyses using Image J. [Participants and Methods] Thirty-eight healthy young males performed the functional reach test (FRT) twice, and their reach movements were recorded using a digital video camera. Image J was used to combine the digital photographs taken at the start position and maximum reach and to measure each movement. The measurements recorded were the movement distance of the third metacarpal bone (reach distance), anterior-superior iliac spine, and trochanter major, and the angles recorded were the acromion-malleolus lateralis, acromion-trochanter major, and trochanter major-malleolus lateralis. The reliability of all the measurements was analyzed using intraclass correlation coefficients (ICCs), Bland-Altman plots, and MDCs. [Results] The ICCs (1, 1) were >0.80 for all the outcomes. The Bland-Altman analysis revealed no systematic bias in any outcome. The MDC of reach distance was 18.3 mm. [Conclusion] Measurement using Image J for reach distance and movement angles in the FRT showed acceptable high test-retest reliability. Measurement of the FRT and the MDC calculated in this study could be used as a reference for further research.Key words: Reliability, Image J, Functional reach test 相似文献

BackgroundThree-dimensional (3D) motion analysis is considered the gold standard for evaluating human movement. However, its clinical utility is limited due to cost, operating expertise, and lengthy data processing time. Numerous qualitative scoring systems have been introduced to assess trunk and lower extremity biomechanics during functional tasks. However, the reliability of qualitative scoring systems to evaluate cutting movements is understudied. Purpose/Hypotheses: To assess the inter-rater and intra-rater reliability of the Cutting Alignment Scoring Tool (CAST) among sports medicine providers and to evaluate rater agreement of each component of the CAST. The hypotheses were: 1) there would be good–to-excellent inter-rater and intra-rater reliability among sports medicine providers, 2) there would be good to almost perfect agreement for cut width and trunk lean variables and moderate to good agreement for valgus variables of the CAST.Study DesignRepeated MeasuresMethodsTen videos of a 45-degree side-step cut performed by adolescent athletes were independently rated on two occasions by six raters (2 medical doctors, 2 physical therapists, and 2 athletic trainers). The variables assessed include trunk lean to the opposite direction of the cut, increased cut width, knee valgus at initial load acceptance (static), and knee valgus throughout the task (dynamic). Variables were scored as either present, which were given a score of “1”, or not present, which were given a score of “0”. Video sequence was randomized in each rating session, and a two-week wash out period was given.ResultsThe cumulative inter-rater and intra-rater reliabilities were good (ICC: 0.808 and ICC: 0.753). Almost perfect kappa coefficients were recorded for cut width (k=0.949). Moderate kappa coefficients were found for trunk lean (k= 0.632) and fair kappa coefficients were noted for dynamic and static valgus (k=0.462 and k= 0.533 respectively).ConclusionThese findings suggest that the CAST is a reliable tool to evaluate trunk and LE alignment during a cutting task by sports medicine providers.Level of EvidenceLevel 2 Diagnosis 相似文献

[Purpose] This study aimed to investigate the test-retest reliability of isometric ankle plantar flexion strength measurements performed by a hand-held dynamometer (HHD) using two belts and a newly devised fixation plate. [Participants and Methods] The participants were 83 healthy individuals (female, n=31; male, n=52) with an average age of 20 years. An HHD (μTas F-1) sensor was fixed using two belts and a newly developed metal device to the measurement site on the dominant foot of a participant who was in a sitting position. Measurements were performed twice for each participant. [Results] The average value was 65.6 kgf (bodyweight ratio, 127.3%) for female and 88.0 kgf (136.9%) for male participants. The intraclass correlation coefficients of the two measurements were 0.915 for female and 0.938 for male participants. The minimum detectable change at 95% was 10.1 kgf (12.1% of the average value) for female and 12.1 kgf (15.4%) for male participants. [Conclusion] The test-retest reliability of measuring the ankle plantar flexion strength performed by an HHD using a belt and plate is high. Therefore, the increase or decrease in muscle strength should be judged based on the minimal detectable change with 95% confidence. 相似文献
