Abstract
BACKGROUND People with cancer usually report physical deconditioning, which can limit daily activities. AIMS Our aim was to analyze associations between daily physical activities and handgrip strength with cancer diagnoses among European older adults. METHODS We used data from SHARE (a representative survey of individuals aged 50 years or older) wave 7, residing in 27 European countries and Israel. Participants self-reported difficulties in daily physical activities and cancer diagnoses, and handgrip strength was objectively assessed using a handheld dynamometer. Data were analyzed using binary logistic regression. RESULTS Overall, 65,980 participants (average age 67.6 years (SD = 9.4)) were analyzed. Having difficulties in any daily physical activity was significantly associated with higher odds of cancer diagnoses. Lower handgrip strength was significantly associated with cancer diagnoses among participants included in the first (adjusted odds ratio (AOR) = 1.27 [95%CI = 1.11-1.45]) and the second third (AOR = 1.15 [95%CI = 1.03-1.28]) when compared with participants from the last third in the final adjusted model. DISCUSSION Having difficulties in daily physical activities as well as lower levels of handgrip strength is positively associated with cancer diagnoses. CONCLUSION Adults with difficulties lifting or carrying weights over 5 kilos or having difficulties in two or more activities showed critical associations with cancer diagnosis.

Abstract
OBJECTIVE Manual muscle strength testing is the primary method for testing muscle strength in clinical settings but is highly subjective. An objective measure of muscle strength can be obtained using a handheld dynamometer, but its cost inhibits its widespread usage. We hypothesized that a spring tensiometer (ST) could be an objective tool that can be used as a viable alternative to a dynamometer. METHODS Twenty-six outpatients were included, and the strengths of several muscle groups were measured using tensiometers and dynamometers. A paired t-test and Pearson's correlation coefficient and Bland-Altman plot analyses were used to estimate the reliability and measurement accuracy of both tools. Multiple regression analysis was performed to identify the factors contributing to the measurement gap between the two instruments. RESULTS A total of 260 muscle force values were evaluated. Pearson's correlation coefficient and Bland-Altman analyses indicated that the measurements of the two instruments were strongly correlated and highly accurate. In the multiple regression analysis, the gap between the two instruments was significantly related to the original muscle strength and muscle part but was not significantly related to sex, age, body mass index, or laterality. For biceps and triceps muscle groups, the correlations were particularly strong and accurate, indicating that a tensiometer could be well substituted for a dynamometer. CONCLUSIONS Our data show that a ST is similar to a dynamometer in terms of precision. A ST is an inexpensive alternative to a dynamometer and more accessible for clinical use than a dynamometer.

Abstract
BACKGROUND Evaluating trunk strength is an important aspect of the physical examination of people with low back pain (LBP). Thus, reliable, valid, and easily applied measurement tools are needed to quantify trunk muscle strength and monitor changes in response to interventions. OBJECTIVES To determine within-day and between-day test re-test reliability and criterion validity of a handheld dynamometer (HHD) to evaluate maximum isometric trunk strength in people with chronic LBP and asymptomatic individuals. DESIGN Reliability and criterion validity study. METHODS Twenty adult participants with chronic, non-specific LBP and 35 asymptomatic individuals participated. Isometric trunk flexion, extension, and rotation strength were evaluated with the HHD (Active force 2) and the within-day and between-day reliability were determined with intraclass correlation coefficients (ICC2,1) and the standard error of the measurements (SEM), minimal detectable change (MDC), and the limits of agreement (LOA) using Bland-Altman plots. Criterion validity was evaluated using Pearson correlation coefficients to compare HHD measurements to isokinetic dynamometry for both isometric trunk flexion and extension strength. RESULTS Good to excellent within-day and between-day reliability was observed for people with LBP and asymptomatic individuals with (ICC2,1) of 0.73-0.93 and 0.62-0.92 respectively. A moderate to strong correlation was found between measurements with the HHD and the isokinetic dynamometer with a correlation of r = 0.68-0.78 and r = 0.56-0.59 for people with LBP and asymptomatic participants respectively. CONCLUSION A HHD is a reliable, valid, and clinically applicable tool for the measurement of trunk strength in adults with and without chronic LBP.

Abstract
BACKGROUND Normative values for hand grip and pinch strength among children in Saudi Arabia has not been well established. Therefore, the main aim of this study is to establish normative values for hand grip and pinch strength in children aged 6 to 18 years in Saudi Arabia. METHODS A cross-sectional study was conducted from different 5 regions in Saudi Arabia. Participants between the age of 6 years and 18 years old were recruited through different primary and secondary schools in Saudi Arabia. Data for age, gender, Body Mass Index, and preferred hand were collected. Hand grip strength was measured using digital hand dynamometer and the tip pinch, palmar pinch, and key pinch strength were measured using the hydraulic pinch gauge. RESULTS A total of 616 participants included in this study (318 boys and 298 girls). Participants were stratified into 5 chronological age groups of 6-7 years, 8-9, 10-11, 12-13, 14-15, 16-17, and 18 years. The results showed an overall trend of increasing hand grip strength and pinch strength with age regardless of hand preference. Boys had significantly higher grip strength than girls in all age groups (P < 0.05). CONCLUSION This study established normative values for hand grip and pinch strength in the healthy Saudi pediatric and adolescent population, using boys and girls aged 6 to 18. The outcomes of this study also demonstrated that gender, age, and hand preference can all have an impact on how strong a handgrip develops.

Abstract
OBJECTIVES Comparative assessment of bilateral (KangaTech) and unilateral (HHD) testing modalities through concurrent validity and test-retest reliability. Methodological considerations explored include minimum repetitions and comparison of average and maximum values. DESIGN Experimental, observational. SETTING Biomechanics laboratory. PARTICIPANTS Thirty-three participants. MAIN OUTCOME MEASURES Concurrent validity using peak force. Test-retest reliability used Abduction and Adduction using 2 trials, randomised between devices. Maximum peak force and average of both trials were used. RESULTS HHD and KT360 are concurrently valid (r = 0.996); with no significant difference (z = -0.681). Excellent HHD reliability (ICC:0.92-0.96) and KT360 (ICC:0.89-0.97). Significant difference between max peak force and average peak force but within the calculated MDC(%). No significant differences between max peak force between trials. Spearman-Brown prophecy predicted excellent reliability for one trial (ICC:0.81-0.95). Bilateral facilitation was demonstrated using the KT360 with 94.6-101.2% increase in force compared to HHD. CONCLUSIONS With no significant difference between first and second max effort, and excellent prophesised reliability, one rep max effort should be acceptable to use. Body positioning within the KT360 seems to elicit bilateral facilitation rather than deficit, therefore unilateral and bilateral force values are not interchangeable.

Abstract
Groin/hip injuries are prevalent in rugby union (RU). Assessment of hip muscle strength is important when designing bespoke injury prevention and rehabilitation programmes. OBJECTIVE The primary aim of this study was to determine normative values of hip muscle strength in elite-level RU players. A secondary aim of this study was to compare the Copenhagen Hip and Groin Outcome Score (HAGOS) between players with and without a history of groin/hip injury. DESIGN Cross-sectional cohort study. SETTING Professional RU club. PARTICIPANTS 58 male professional RU players competing in the PRO14 league elite club level competition. MAIN OUTCOME MEASURES Handheld dynamometry eccentric strength values of hip abduction (ABD), adduction (ADD), internal rotation (IR) and external rotation (ER), HAGOS. RESULTS Players' dominant (DOM) and non-dominant (NDOM) hip strength values were, 2.38 and 2.34 N m/kg for ABD, 2.79 and 2.71 N m/kg for ADD, 2.69 and 2.55 N m/kg for IR, and 2.65 and 2.54 N m/kg for ER. ADD:ABD strength ratio was 1.17 ± 0.26 for the DOM limb and 1.16 ± 0.24 for the NDOM limb. There was no clinically significant difference in strength between players' DOM and NDOM limbs. Players with a history of groin/hip injury scored lower on four of the HAGOS subscales (pain; symptoms; sport; quality of life) compared to those without a history of groin/hip injury. CONCLUSIONS This study may help establish normative hip strength and HAGOS values for elite-level RU players. The results presented have important implications for the assessment of hip muscle strength and could provide clinical markers for return-to-play following injury.

Abstract
BACKGROUND The use of predictive equation of muscular torque can reduce physical effort and time spent during evaluation. OBJECTIVES To establish, validate, and test the accuracy of a prediction equation to estimate the hip external rotators (HER) torque in adults and older adults by means of hip extensors (HEX) torque measurement. METHODS Eighty-three healthy adults (development set) were assessed to test the association of HEX and HER torques and to establish the prediction equation. A separate 36 adults and 15 older adults (validation sets) were assessed to test the ability of the equation to estimate HER torque. Hip isometric strength was assessed by a handheld dynamometer. RESULTS Simple linear regression analysis revealed that HEX torque was associated with HER torque (r=0.80; p<0.0001), resulting in the following prediction equation: HERtorque=-0.02+(0.58 * HEXtorque). Paired t-test revealed no difference between directly measured and predicted values of HER torque in adults (mean difference=0.02; 95% CI=-0.115, 0.072) and older adults (mean difference=0.05; 95% CI=-0.02, 0.12). CONCLUSION The HEX and HER torques were strongly correlated. The prediction equation was valid, accurate, and can be used to estimate HER muscle strength in healthy adults and older adults, requiring only the direct measurement of HEX torque.

Abstract
[Purpose] It is important to accurately measure one-repetition maximum to determine the
training load and number of repetitions. However, huge and expensive equipment, such as a
torque machine and/or dynamometer, is needed to measure one-repetition maximum. Therefore,
a more accessible and affordable method has been developed to predict one-repetition
maximum. In this study, we aimed to investigate whether one-repetition maximum of the knee
extensor could be predicted more accurately with a combination of muscle strength,
measured using a handheld dynamometer, muscle thickness, and thigh circumference.
[Participants and Methods] Participants were sixty-four non-athletic healthy adult
volunteers (33 males and 31 females). Muscle strength of the knee extensor measured using
one-repetition maximum, maximal voluntary isometric contraction measured using a handheld
dynamometer, muscle thickness of the quadriceps and/or thigh circumference measured on
ultrasonography. [Results] The stepwise regression analysis revealed that body mass,
gender, muscle thickness at 15 cm above the patella, and maximal voluntary isometric
contraction were the significant and independent determinants (R2=0.813).
[Conclusion] One-repetition maximum could be predicted more accurately with a combination
of maximal voluntary isometric contraction measured using a handheld dynamometer and
muscle thickness.

Abstract
The purpose of this study was to assess the relative and absolute reliability of a handheld dynamometer when used for examining elbow flexion power in patients with brachial plexus palsy. The assessment of the intra-rater and inter-rater reliability coefficients for the handheld dynamometer was done using the stationary Kin-Com® dynamometer as the reference standard. We determined the measurement errors and checked the systematic biases of the handheld dynamometer. The inter-rater and intra-rater reliabilities of the handheld dynamometer had a very high intraclass correlation coefficient. The values of handheld dynamometer readings had a high correlation to Kin-Com® readings. The Medical Research Council grading was a comparatively inaccurate method for quantitative assessment of motor power. We conclude that a handheld dynamometer measurement is more precise and reliable than the Medical Research Council grading for measuring recovery of elbow flexion in patients with brachial plexus palsy. Level of evidence: III.

Abstract
OBJECTIVE Isometric muscle strength measured by Handheld dynamometer indicates physical ability. There is no normative data for the Brazilian population. This study aims (a) to describe the development of isometric muscle strength in healthy children and adolescents 5-15 years of age; (b) to evaluate Handheld dynamometer inter and intra-rater reliability. METHODS Isometric muscle strength was obtained for shoulder abduction, elbow and knee flexion and extension, dorsiflexion and plantar flexion in 55 boys and 55 girls, aged between 5 and 15 years. Inter-rater reliability was determined based on the evaluation of 2 raters, with a 20-min interval between them. Intra-rater reliability was based on 2 evaluations from the same rater, one week apart. Interclass correlation coefficient (ICC2,1; 3,1), Bland Altman plots and linear regression models with mixed effects were used to quantify inter and intra-rater reliability, agreement and associations with physical activity level and maturational factors. RESULTS A linear development of isometric muscular strength was observed for ages between 5 and 10. After age 10, boys showed a larger isometric muscular strength, when compared to girls. Both inter and intra-rater measurements of the Handheld dynamometer are reliable (ICC>0.63). CONCLUSIONS This study shows increase in isometric muscle strength starting at 10 years of age for boys, when compared to girls and inter and intra-rater reliability for the assessment of isometric strength, using the Handheld dynamometer for the muscle groups tested on the dominant and non-dominant side, for children between 5 and 15 years of age.

Abstract
[Purpose] To study the effect that limbering up of the muscles attached to the pelvis has
on muscle strength of the trunk and upper and lower extremities, which are not being
exercised, and to investigate the possibilities for clinical application. [Subjects and
Methods] A total of 152 healthy adult men. Sthenometry was conducted using a handheld
dynamometer to assess the effect of limbering up of the upper gluteus maximus, hamstrings,
and internal abdominal oblique muscles attached to thoracolumbar fascia on the trunk and
upper and lower extremities. The exercises were slowly performed 20 repetitions. Subjects
were divided into AB group (n=49) measuring abdominal and back muscle strength, K group
(n=42) measuring knee flexor and extensor strength, and S group (n=61) measuring shoulder
flexor and external rotator strength and compared to non-exercising controls. [Results] In
the exercise groups, exercising either gluteus maximus or hamstrings significantly
increased the strength of abdominal and back muscles; exercising gluteus maximus increased
knee extensor strength, and exercising the abdominal internal oblique muscle significantly
increased knee flexor strength; and shoulder flexor strength significantly increased after
exercising gluteus maximus versus controls. [Conclusion] This may be useful in
rehabilitation of injuries to the trunk and upper and lower extremities.

Abstract
BACKGROUND The shoulder complex is highly loaded during swimming. No studies were found analyzing the changes in shoulder girdle strength in young swimmers, through the years. OBJECTIVE To analyze the changes in strength of internal rotators and external rotators of the arm, lower trapezius and supraspinatus and in the external rotators/internal rotators ratio in young elite swimmers through 3 years. METHODS 31 adolescent elite swimmers (14-18 years, of both sexes) participated in the study. Isometric strength of the shoulder girdle muscles was performed using a handheld dynamometer during 3 years. RESULTS For boys absolute data, internal rotators increased from the first to the second (p=0.0001; mean difference 45.6N; 95%CI 26.7-65.0) and third years (p=0.01; mean difference: 32.4; 95%CI: 9.3-55.5). Considering the weight-normalized data, internal rotators increased from the first to the second year (p<0.0001; mean difference: 0.52; 95%CI: 0.26-0.78), external rotators decreased from the first to the third year (p=0.003; mean difference: -0.33; 95%CI: -0.53 to -0.13) and from the second to the third year (p=0.0004; mean difference: -0.29; 95%CI: -0.46 to -0.12) and supraspinatus decreased from the second to the third year (p=0.006; mean difference: -0.17; 95%CI: -0.28 to -0.06). For girls, there were no significant differences in the absolute strength. Considering the weight-normalized data, lower trapezius decreased from the first to the third year (p=0.02; mean difference: -0.15; 95%CI: -0.27 to 0.03). Considering both sexes, the external rotators/internal rotators ratio decreased from the first to the second (p<0.0001; mean difference -0.12N; 95%CI -0.13 to -0.11) and third years (p<0.0001; mean difference -0.15N; 95%CI -0.16 to -0.14). CONCLUSION Muscle imbalance can occur in the shoulder girdle in young swimmers in 3 years, with increased internal rotators and decreased external rotators and supraspinatus strength in boys, and decreased strength of the lower trapezius in girls. Attention should be given in young swimmers' shoulder girdle muscle balance.

Abstract
[Purpose] No literature has described a suitable method for measuring muscle strength in a supine position during acute phase after stroke. This study investigated the feasibility and reliability of using a commercial handheld dynamometer to measure the muscle strengths of the hip flexor, knee extensor, and dorsiflexor in the supine position with a modified method for patients at a stroke intensive care center within 7 days of stroke onset. [Subjects and Methods] Fifteen persons with acute stroke participated in this cross-sectional study. For each patient, the muscle strengths of the hip flexors, knee extensors, and dorsiflexors were measured twice by two testers on the same day. Each patient was re-tested at the same time of day one day later. Inter-rater and test-retest reliability were then determined by the intraclass correlation coefficients (ICCs). [Results] For the three muscle groups, the inter-rater reliability ICCs were all 0.99 and the test-retest reliability ICCs were greater than 0.85. The investigated method thus has good inter-rater reliability and high agreement between the test-retest measurements, with acceptable measurement errors. [Conclusion] The modified method using a handheld dynamometer to test the muscle strength of acute stroke patients is a feasible and reliable method for clinical use.

Abstract
[Purpose] This study aimed to investigate the effect of trunk stability on isometric knee
extension muscle strength measurement while sitting by performing simultaneous
measurements with a handheld dynamometer (HHD) and an isokinetic dynamometer (IKD) in the
same seated condition. [Subjects and Methods] The subjects were 30 healthy volunteers.
Isometric knee extension muscle strength was simultaneously measured with a HHD and an IKD
by using an IKD-specific chair. The measurement was performed twice. Measurement
instrument variables and the number of measurements were examined by using the analysis of
variance and correlation tests. [Results] The measurement instrument variables and the
number of measurements were not significantly different. The correlation coefficients
between the HHD and IKD measurements were ≥0.96. [Conclusion] Isometric knee extension
muscle strength measurement using the HHD in the sitting position resulted in a lower
value than that using the IKD, presumably because of the effect of trunk stability on the
measurement. In the same seated posture with trunk stability, no significant difference in
measurement values was observed between the HHD and IKD. The present findings suggest that
trunk stability while seated during isometric knee extension muscle strength measurement
influenced the HHD measurement.

Abstract
[Purpose] This study aimed to verify the appropriate number of measurements and the
intrarater reliabilities of shoulder joint horizontal adductor muscle strength
measurements using a handheld dynamometer (HHD) for geriatric and stroke patients.
[Subjects and Methods] The subjects were 40 inpatients, who were divided into two groups:
20 stroke patients in the stroke group (SG), and 20 geriatric patients in the no-stroke
group (N-SG). Measurements were performed three times using an HHD with a belt. The
reliability was verified using Bland-Altman analysis and the intraclass correlation
coefficient (ICC). [Results] ICC (1, 1) was >0.9. A systematic bias was not observed
between the first and second measurement values except for the right side in N-SG. A
systematic bias between the maximum value obtained during the first and second
measurements and third measurement value was observed on the left side in N-SG, and on the
non-paralyzed side in SG: the third measurement values were small in both cases.
[Conclusion] Intrarater reliabilities were high for shoulder horizontal adductor strength
measurements using an HHD with a belt for geriatric and stroke patients. Taking the
systematic bias into consideration, these findings suggest that the required number of
measurements is two.

Abstract
[Purpose] The purpose of this study was to assess the relationships between bilateral
knee extension strengths and gait performance in subjects with poststroke hemiparesis and
to predict gait performance by the paretic and nonparetic knee extension strength.
[Subjects and Methods] This was a correlational study in which 238 consecutive inpatients
with poststroke hemiparesis were enrolled. Knee extensor muscle strengths in paretic and
nonparetic lower limbs were measured with a handheld dynamometer, and the presence or
absence of impaired gait was also determined. [Results] The mean strength in the paretic
lower limb was 0.90 Nm/kg, and that in the nonparetic lower limb was 1.24 Nm/kg.
Discriminant analysis classified the difference between the possibility and impossibility
of gait by knee extensor muscle strength (standardized discriminant coefficient: paretic,
1.32; nonparetic, 0.55). Thus, paretic and nonparetic knee extension strengths were
integrated in the strength index. A threshold level of 2.0 provided the best balance
between positive and negative predictive values for the strength index. [Conclusion] The
results indicated that both paretic and nonparetic knee extension strengths were related
to gait performance. The strength index deduced from bilateral knee extension strengths
may serve as a clinically meaningful index for rehabilitation assessment and training.

Abstract
[Purpose] The aim of this study was to verify the absolute reliability of shoulder joint horizontal adductor muscle strength measurements using a handheld dynamometer (HHD). [Subjects and Methods] The subjects were 33 healthy college students. The measurements were made three times with the HHD fixed using a belt (BFHHD) or with the examiner's hand (conventional method; HFHHD). The absolute reliability of measurements was verified using Bland-Altman analysis, both in the all subjects group and a group of subjects showing measurements less than a fixed limit of 30 kgf. [Results] In the <30 kgf group, a systematic bias was not observed, and BFHHD values were greater than HFHHD values. BFHHD values in the all subjects group showed a systematic bias; the 3rd measurement value was less than the maximum value obtained during the 1st and 2nd measurements. [Conclusion] For obtaining an acceptable value during clinical measurements of horizontal adductor muscle strength, single measurements obtained using an HFHHD in the case of a <30 kgf group and the maximum value of two measurements obtained using a BFHHD are reliable.

Abstract
[Purpose] To investigate whether an objective evaluation method for trunk function,
namely the “trunk righting test”, is reproducible and reliable by testing on different
observers (from experienced to beginners) and by confirming the test-retest reliability.
[Subjects] Five healthy subjects were evaluated in this correlation study. [Methods] A
handheld dynamometer was used in the assessments. The motor task was a trunk righting
motion by moving the part with the sensor pad 10 cm outward from the original position.
During measurement, the posture was held at maximum effort for 5 s. Measurement was
repeated three times. Interexaminer reproducibility was examined in two physical
therapists with 1 year experience and one physical therapist with 7 years of experience.
The measured values were evaluated for reliability by using intraclass correlation
coefficients (ICC 1.1) and interclass correlation coefficients (ICC 2.1). [Results] The
test-retest reliability ICC 1.1 and ICC 2.1 were all high. The ICC 1.1 was >0.90. The
ICC 2.1 was 0.93. [Conclusion] We developed the trunk righting test as a novel objective
evaluation method for trunk function. As the study included inexperienced therapists, the
results suggest that the trunk righting test could be used in the clinic, independent of
the experience of the therapists.

Abstract
[Purpose] The aim of this study was to develop a method of measuring isometric shoulder
joint muscle strength using a handheld dynamometer with a belt and investigate its
test-retest reliability. [Subjects] The subjects comprised 40 healthy adults. [Methods]
Six types of isometric shoulder muscle strength were measured twice, and reliability was
assessed. [Results] The intraclass correlation coefficient (1, 1) values ranged from 0.976
to 0.902. The result of a Bland-Altman analysis showed differences in the types of errors
between measurement items. [Conclusion] The relative reliability of isometric shoulder
muscle measurement using a handheld dynamometer with a belt was high. However, analysis of
absolute reliability revealed errors that may affect interpretation of values; therefore,
it was considered that adapting the greater of two measurement values is appropriate.

Abstract
[Purpose] The aim of this study was to verify the limit of isometric muscle strength of
shoulder joint horizontal adduction using handheld dynamometer (HHD) manipulated by hand
(referred to as the manipulative-fixed method). [Subjects and Methods] The subjects were
33 healthy college students. The examiner was a healthy college student. Shoulder joint
horizontal adductor muscle strength was measured using HHD with the subject in the supine
position. The belt-fixed and manipulative-fixed methods were used to secure the HHD sensor
unit. The limitations of the manipulative-fixed method were assessed by simple regression
analysis, in which the participants were divided into 2 groups according to a branch
point. The slope of the straight line of the graph was visualized. [Results] Single
regression analysis of the <30 kgf group revealed significant results. The results of
single regression of the >30 kgf group were not significant. [Conclusion] The
manipulative-fixed method is simple to perform. However, there exists the possibility that
the actual muscle strength is not measurable by this method. The measurement limit of the
shoulder horizontal adduction strength with the manipulative-fixed method was 30 kgf in
the case of the examiner in the present study. The fixed limit was also found to influence
in the muscle strength of the upper limbs.
