“…Quantifying the magnitude of strength is useful for rehabilitation programs, providing helpful information on setting target values, for setting up appropriate exercise loads, and the effectiveness and progress of treatment [ 1 ]. The evaluation of strength is one of the usual practices by health professionals to assess healthy individuals [ 2 , 3 , 4 ] and in the management patients with different lower limb or upper limb pathologies [ 5 ], such as knee osteoarthritis [ 6 ], rotator cuff injuries [ 7 ], and neurogenic thoracic outlet syndrome [ 8 ]. Among the tools to measure strength in clinical sitting, the most used is hand held dynamometers (HHDs) [ 9 ], since it has advantages such as portability, cost, and ease of use compared to other more expensive and less versatile methods (i.e., isokinetic dynamometer) [ 10 ].…”

Hand held dynamometers (HHDs) are the most used method to measure strength in clinical sitting. There are two methods to realize the assessment: pull and push. The purpose of the present study was to evaluate the intra- and inter-rater reliability of a new measurement modality for pull HHD and to compare the inter-rater reliability and agreement of the measurements. Forty healthy subjects were evaluated by two assessors with different body composition and manual strength. Fifteen isometric tests were performed in two sessions with a one-week interval between them. Reliability was examined using the intra-class correlation (ICC) and the standard error of measurement (SEM). Agreement between raters was examined using paired t-tests. Intra- and inter-rater reliability for the tests performed with the pull HHD showed excellent values, with ICCs ranging from 0.991 to 0.998. For tests with values higher than 200 N, push HHD showed greater differences between raters than pull HHD. Pull HHD attached to the examiner’s body is a method with excellent reliability to measure isometric strength and showed better agreement between examiners, especially for those tests that showed high levels of strength. Pull HHD is a new alternative to perform isometric tests with less rater dependence.

“…Isokinetic machine despite being the gold standard, is highly expensive and time consuming equipment which is why it is not readily accessible for most practitioners. 7 On the other hand, HHD can be used as an alternative tool to isokinetic machine as they are time sufficient, portable and relatively low-cost method of measuring strength. 8 Another advantages of HHD include a quick tool of providing objective values in clinic and experimental settings.…”

Objectives: To determine the inter-rater and intra-rater reliability of the hand-held dynamometer in measuring isometric gluteus medius muscle strength in asymptomatic healthy population. Methods: It was a cross sectional study conducted at the department of physiotherapy, Sindh Institute of Physical Medicine and Rehabilitation from March 2021 to April 2021. Thirty healthy subjects aged 18 to 25 years of both sexes and no previous or current complaints of hip or knee pain were included through non-probability purposive sampling technique. The strength of the unilateral isometric gluteus medius muscle was measured using a hand-held dynamometer by two raters at the same day and a week later. Pearson Correlation coefficient was calculated to see the relationship of muscle strength measured by each rater within and between day’s sessions. Intra–class correlation was calculated with 95% confidence interval and Standard error of measurements using reliability analysis. Results: In the present study there were thirty participants studied by two raters, the mean age of participants was 21.53 (SD=±1.40) years, the mean BMI was 24.05 (SD=±1.12) kg/m2 and 70% participants were female and 30% were males. This study showed the mean muscle measurement of participants within days was 12.92 (SD=±0.94), with intra-class correlation ICC (2,2) 0.94 and SEM 0.12 and mean muscle measurement of patients between days was 12.99 (SD=±0.91), with intra-class correlation ICC (2,2) 0.90 and SEM 0.12. Conclusion: Hand-held dynamometer has shown excellent inter-rater and intra-rater reliability in measuring isometric strength of Gluteus Medius muscle among healthy population. It is convenient to be used in clinical settings and can be a useful outcome tool to assess strength in interventional studies. doi: https://doi.org/10.12669/pjms.38.5.5207 How to cite this:Soomro RR, Karimi H, Gillani SA.

“…In clinical practice, a dynamometer is a kind of popular quantifiable appliance for sports and rehabilitation training as it is simple to use, portable, and cost-effective. However, it can only be used to measure the strength of certain synergistic muscle groups ( Ashall et al, 2021 ; Tanveer et al, 2021 ), and it cannot be utilized to establish biomechanical studies on individual muscles in vivo .…”

Purpose: Monitoring the contractility of muscles assists the clinician in understanding how muscle functions as part of the kinetic system. This study investigated the effect of knee joint angles under different resistance on the stiffness of the medial gastrocnemius (MG), lateral gastrocnemius (LG), and soleus (SOL) muscles using the shear wave elastography (SWE) technique.Methods: A total of 22 females were recruited. During isometric plantar flexion, at knee 0-degree (fully extended) and knee 90-degree (flexed 90°), the shear modulus on the MG, LG, and SOL was measured by shear wave elastography at no contraction and two intensities (40% and 80%) of maximal voluntary contraction (MVC). Shear modulus is a mechanical parameter to describe stiffness, and stiffness is a proxy for muscle contractility.Results: There were moderate-to high-positive correlations between the active stiffness of triceps surae muscles and isometric contraction intensity (r: 0.57–0.91, p＜0.001). The active stiffness in MG and LG with extended knees was higher than that with flexed knees (p＜0.001). The active stiffness in SOL with flexed knee was higher than that with extended knee (p＜0.001).Conclusion: Active stiffness can be considered a quantitative indicator generated by the force output of the triceps surae. Different knee joint angles cause three triceps surae muscles to exhibit non-uniform mechanical properties, which may explain part of the mechanism of soft tissue injury during physical exercise.
