“…15,16 We think that average strength scores showed a better correlation with motor performance than maximal strength scores. This was confirmed by Morris et al, 17 who reported that no more than 3 tests should be carried out. When evaluating the reliability between tests we discovered that they were very similar, especially for patients.…”

Context: Handheld dynamometry (HHD) is considered an objective method of measuring strength, but the reliability of the procedure can be compromised by inadequate tester strength and insufficient stabilization of the dynamometer especially, for the scapular muscles. Objective: Primarily, to determine the intrarater reliability of HHD when testing shoulder and scapular muscle strength, and secondarily, to report reliability when corrected for body-mass index (BMI). Design: Technical report. Setting: University physiotherapy department. Participants: 57 adults (17 men, 40 women; mean age = 35.05 ± 13.5 y), both healthy individuals and patients with shoulder impingement. Intervention: HHD. Main Outcome Variables: Muscle strength of the upper, middle, and lower trapezius; anterior deltoid; serratus anterior; supraspinatus; and latissimus dorsi determined by HHD. Each muscle was assessed 3 times, and the mean value was calculated. The subjects were divided into 3 groups according to BMI. Group 1: BMI ≤ 20 kg/m 2 (n = 22); Group 2: BMI ≤ 24.9 kg/ m 2 (n = 54); and Group 3: BMI ≤ 29.9 kg/m 2 (n = 38). Results: Correlations were calculated for each pair of strength scores. Intraclass correlation coefficients (ICCs) ranged from .77 to .99 in healthy subjects and from .75 to .99 in patients, for all muscle groups except the upper trapezius (P < .05). Reliability values ranged from good to high in healthy subjects but were less consistent for the upper trapezius (ICC .45-.65). The relationship with BMI and muscle strength illustrates that as BMI increases, there is a decrease in reliability values of the lower trapezius (ICC = .35-.65). Conclusion: The study demonstrates that evaluating the strength of scapular and shoulder muscles using HHD presents reliable results for both patients with impingement syndrome and healthy subjects. Reliability values were compressed when testing the trapezius in subjects with higher BMI. This is likely a result of the examiner's difficulty in overcoming the patients with this maneuver.

“…Measures of impairments of body structure and function (such as dynamometry to measure muscle strength [48]) or of the ability to perform routine activities (such as the functional independence measure [49]) can be used to evaluate control of one's body following TBI. Likewise, measures of mood exist that have been considered suitable for evaluation of the emotional consequences of TBI (such as the Beck Depression Inventory [50]), while tools for objectively measuring community integration could ostensibly be used to evaluate the degree of loss and reconstruction of one's place in the world [51].…”

“…The portable dynamometers, which record the maximal isometric force generated during an isometric contraction (22), have been used to assess the strength of the trunk (14,23), UL (24)(25)(26)(27), and handgrip (9, 12, 28) and pinch (29)(30)(31) muscles of subjects with stroke. They are practical devices that can be placed between the examiner's hand and the muscle group to be tested, similar to the MMT assessment (32) or used with the subject exerting force directly on the equipment, in the case of handgrip and pinch assessments (33)(34)(35)(36).…”

Assessment of the strength of the trunk and upper limb muscles in stroke subjects with portable dynamometry: a literature review

et al. 2015

Introduction Clinical measurements of strength in stroke subjects are usually performed and portable dynamometers are one of the most employed instruments. Objective To verify the standardization procedures of the methods used to assess the strength of the trunk and upper limb muscles with portable dynamometers in stroke subjects, as well as to assess the psychometric properties which were already investigated. Materials and methods An extensive search was performed on the MEDLINE, SciELO, LILACS, and PEDro databases, by combining specific key words, followed by active manual searches by two independent researchers. Results and discussion Fifty-eight studies were included: three related to the trunk and 55 to the upper limb muscles, including handgrip and pinch strength assessments. The most investigated muscular groups were handgrip, elbow flexors/extensors, wrist extensors, and lateral pinch. Nine studies reported adequate reliability levels and the seated position was employed in the majority of the studies which assessed trunk, handgrip, and pinch strength, while the supine position was used for the other muscular groups. The number of trials most used was three, while the reported contractions and rest times were variable. Final considerations Most studies reported the positioning and/or the data collection protocols; however, there was no consensus on the standardization procedures. The only investigated psychometric property was reliability. Few studies evaluated the trunk muscles and other psychometric properties.
