“…These results are slightly higher than the correlation values (r=.76 -.78) previously reported between the MF2 and isokinetic machines. 17,18,20 Such strong correlations strengthen the external validity and clinical utility of this new AF and are in line with recent claims in the literature that HHD muscle force testing should be considered a valid and an acceptable, clinically meaningful alternative to other externally fixed and expensive isokinetic dynamometers. 28 This study is strengthened by both its observational design and methodological approach.…”

“…12 In this study, the criterion-standard device was the MF2, which has been strongly validated against an isokinetic device for testing shoulder isometric strength in healthy adults. 17,18,20 This study's results confirmed that the AF strongly correlates (r =.89 -.93) with its counterpart MF2 HHD in testing shoulder ER, IR, and FE muscle force. These results are slightly higher than the correlation values (r=.76 -.78) previously reported between the MF2 and isokinetic machines.…”

“…3,13,14 Similarly, the MF2 has been found to be highly reliable among healthy adults. 15 Its moderate-to-high (r ≥.50) concurrent validity has also been established against isokinetic testing [16][17][18][19][20] among injury populations 16,21 that include the shoulder 17,18,20 as well as in healthy adults. 19 Thus, it can be considered a criterion-standard for assessing muscle force production.…”

Background Currently available hand-held dynamometers (HHD) offer a more objective and reliable assessment of muscle force production as compared to a manual muscle test (MMT). Yet, their clinical utility is limited due to high cost. The ActivForce (AF) digital dynamometer is a new low-cost HHD with unknown psychometric properties, and its utilization may benefit clinical practice. Hypothesis/Purpose This study aimed to determine the AF intra- and inter-tester reliabilities, standard error of measurement (SEM), minimal detectable change (MDC), and criterion validity for assessing shoulder isometric force as compared to the microFET2 (MF2) across testers with different experiences. Design Descriptive observational study. Methods A convenience sample of 29 healthy adults were assessed twice by each of three testers (two experienced clinicians and a novice PT student) on shoulder external rotation (ER), internal rotation (IR), and forward elevation (FE) using both the AF and MF2 devices. Tester, HHD, and shoulder motion assignment orders were randomized. All testing was performed in a standardized seated position. ER and IR were tested with the shoulder fully adducted. FE was tested at 45° at the scapular plane. All testing and rest periods between testers and tested motions were standardized and monitored via a stopwatch. Results Both devices had high intra- [ ER (.95-.98), IR (.97 - .99), FE (.96 - .99)] and inter-tester [ ER (.85-.96), IR (.95 - .97), FE (.88 - .95)] intraclass correlation coefficient (ICC) with comparable intra- (1.68-1.80) and inter-tester (2.36-2.98) SEM, and intra- (4.64-4.97) and inter-tester (6.50-8.24) MDC values across all motions. Tester experience did not affect these values. High (.89-.93) statistically significant Pearson correlations were found between HHDs for all shoulder motions. Conclusion Both the AF and MF2 HHDs were found to have high reliability levels across all shoulder motions regardless of tester clinical experience. The AF was also found to be valid for measuring shoulder isometric force production compared to the criterion standard device, the MF2. Its low-cost and electronic accessibility features may promote better compliance for clinicians using dynamometry to objectively assess and store muscle force data in a cost-effective manner.

“…The difference between the measurement protocols is restricted to the fact that the study by Magnusson et al 25 the measurement of HHD was performed in a seated position, while in the present study all measurements were performed in the supine position. Karabay et al 13 in a study with 25 healthy individuals found concurrent validation of 0.76 for eccentric isotonic abduction of the shoulder with an angular velocity of 30°/s. Such value was lower than the validation found in the present study.…”

“…Hand-held dynamometer (HHD) is a portable, low-cost, reliable and objective way to obtain strength measurements of several appendicular and axial muscles in our body. Its usefulness is very promising in patients unable to access ID, such as hospitalized, home care and skilled nursing facilities patients and less developed cities without a reference physical rehabilitation center [10][11][12][13] .…”

Background: The shoulder complex has a high prevalence of injuries. It is fundamental to quantify the muscle strength and identify muscular imbalances that predispose to lesions. The aim was to test concurrent validation of the muscle strength assessment with a hand held dynamometer (HHD) for shoulder joint muscles, and measure the accuracy and diagnostic agreement between instruments for assessing the strength of this joint with the hand held dynamometer and isokinetic dynamometer (ID) in a population of healthy individuals Methods: healthy individuals aged between 18 and 40 years were included. The HHD was used to test the isometric contraction of the main shoulder movements. Isometric contraction was performed for 3 seconds. Assessments with HHD and DI were performed on the same day, with a minimum interval of 90 minutes between tests. The study was approved by the Ethics Committee by report No.1537948. Concurrent validation was calculated with Pearson’s correlation, the accuracy obtained by the ROC curve and agreement by Kappa test. Results: The HHD showed concurrent validation between 0.51 – 0.83, with sensitivity between 0.90 and 0.98 and specificity between 0.64 and 0.89 for shoulder movements. The HHD demonstrated moderately-strong to excellent concurrent validity. Conclusion: These results are encouraging for the routine use of this portable and lower cost instrument in quantification of the pique torque of the shoulder muscles. Moreover, this instrument showed good accuracy and moderate to high agreement in comparison with diagnosis of the gold standard instrument.
