“…Direct comparison of the HHD results from this study with others can be seen in Table 3. Both Weng et al [3] (Nm/Kg) and Katoh et al [4] (N) reported isometric strength differently to us (Nm/m). Whilst both used healthy subjects Katoh et al [15] did not report the participants as athletic and this could explain the higher scores in this study.…”

“…Both Weng et al [3] and Katoh et al [4] found higher scores in the isokinetic method and speculated that this may because of the increased stabilisation that an isokinetic chair provides but also concluded that the HHD isometric method showed moderate to high correlations and could be considered a valid measure of strength. This is supported in a literature review of hip and knee muscle function testing by Maffiuletti [20] who concluded that it may even be preferable because of its relative simplicity and reliability.…”

“…It has been demonstrated that the HHD is a reliable test of strength, with a moderate-high correlation to a Cybex isokinetic dynamometer in healthy male and female participants (knee extension r = 0.71, r 2 = 0.504 [3], p = 0.001; hip abduction r = 0.49-0.65, p < 0.05, knee extension r = 0.48, p = <0.01 [4]; knee extension r = 0.91 [5]). However, anecdotal clinician feedback from Selfe et al [2] suggested that the use of a HHD muscle strength test, although acceptable for research purposes, is regarded as expensive and impractical in routine clinical practice.…”

Objectives:To test the construct validity of the modified Star Excursion Balance Test (SEBT) in predicting the strength of knee extensors and hip abductors and to compare performance between dominant and non-dominant legs.Strength, as measured using hand held dynamometry, has been used as one of a variety of measures in order to subgroup patients with patellofemoral pain. This method is not well received in clinical practice due to time constraints and cost. In contrast, the SEBT is a quick and simple functional measure of dynamic stability. This study examined the validity of the SEBT as an alternate strength measure.Design: Within subject correlation. Each participant recorded maximum isometric contractions for hip abduction and knee extension using a HHD and performed the modified SEBT, on both legs, within one test period. Paired t tests were used to compare dominant and non-dominant legs and Pearson's correlation analyses were used to explore for associations. Setting: Non-clinical environment,Participants: Eighteen healthy male amateur runner's between 18 and 39 years old (mean age 36.1 years). Main outcome measures:Knee and hip moments normalised for leg length (Nm/m) for the HHD and percent of leg length reach score for each SEBT reach as well as a composite of all three.Results: There was no significant difference between dominant and non-dominant legs for all the tests (knee extension p = 0.72, hip abduction p = 0.90, SEBT composite p = 0.86) therefore data was combined into one set. There was no significant relationship between either hip abduction strength (r = 0.28, p = 0.11), or knee extension strength (r= 0.16, p = 0.17), with any combination of the SEBT. A moderate relationship (r = 0.52, p = 0.38) between hip abduction and SEBT posterolateral reach was seen, however, this was not statistically significant. Conclusion:There was no statistically significant association between either knee extension or hip abduction strength with the modified SEBT. This suggests that strength is unlikely to be a primary construct of the test and the SEBT is not a useful replacement for the HHD when testing strength.

[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.

“…The isokinetic dynamometer is the gold standard for muscle strength assessment, but it is extremely expensive [1]. The hand held dynamometer (HHD) is a portable option with validity and reliability comparable to isokinetic dynamometry when assessing isometric muscle strength in several joint movements [1,13,14]. It is important to note the equipment's anchoring method when the strength test is performed using an HHD in order to maintain the validity and reliability [15].…”

Purpose. To determine the validity, intra-rater reliability, and inter-rater reliability of an anchored sphygmomanometer for assessing shoulder strength during scaption, lateral rotation, and medial rotation. The hand-held dynamometer (HHD) was used as the standard measurement tool for this purpose. Methods. Fifty subjects (23 years old ±3 years) were included in the validity study. shoulder strength was assessed using an HHD and a sphygmomanometer, both anchored to a fixed ladder by an inextensible belt. Twenty-three subjects (25 years old ±3 years) were included in the reliability study. Two raters assessed strength, each taking two measurements one week apart, using the fixed sphygmomanometer. Results. Validity results showed high to very high magnitude correlations, and no differences were found between the sphygmomanometer and the HHD measurements or among trials. Intra-class coefficient of correlation (Icc) showed high reliability between measurement tools and among trials. Intra-rater results showed very high Icc, very high correlation, low coefficient of variation (cV) with adequate standard error of measurement (sEM), and minimal detectable change (MDc). Inter-rater results showed moderate to high Icc, high to very high correlation, acceptable sEM and cV, but not adequate MDc. The anchored sphygmomanometer is a low-cost tool that provides objective measurements. The results obtained from the anchored sphygmomanometer were found to be similar to those obtained from an HHD, which has a valid predictive model. Conclusions. The sphygmomanometer is suitable for monitoring shoulder strength during scaption, internal rotation, and external rotation. The anchored sphygmomanometer enables coaches and physical therapists to establish the maximal voluntary isometric contraction and monitor exercise program outcomes at a low cost. However, caution is recommended when interpreting results between raters.
