“…Therefore, the effect of device deformation was driven by the strongest participants in the study. In clinical studies using the LSMD [ 30 , 31 , 62 ], participants were not likely strong enough to deform the LSMD. Nevertheless, the need for a correction at all remains a design concern.…”

“…This study only included the upper-extremity LSMD for the elbow joint. Although it is likely that the LSMD knee device (discussed in [ 30 ]) behaves similar to the elbow device, since it is essentially a scaled-up version of the arm model, future studies will need to apply the testing protocol to evaluate reliability and validity of the LSMD for lower-extremity assessment.…”

“…All tests were conducted at the Andrew and Marjorie McCain Human Performance Lab at the University of New Brunswick. Standard protocols for HHD [ 40 ], IKD [ 41 ] and LSMD [ 30 , 31 ] were employed for isometric strength testing. Briefly, the elbow was palpated to locate the lateral epicondyle which was designated as the axis of rotation of the elbow joint.…”

Muscle strength is an important clinical outcome in rehabilitation and sport medicine, but options are limited to expensive but accurate isokinetic dynamometry (IKD) or inexpensive but less accurate hand-held dynamometers (HHD). A wearable, self-stabilizing, limb strength measurement device (LSMD) was developed to fill the current gap in portable strength measurement devices. The purpose of this study was to evaluate the reliability and validity of the LSMD in healthy adults. Twenty healthy adults were recruited to attend two strength testing sessions where elbow flexor and extensor strength was measured with the LSMD, with HHD and with IKD in random order, by two raters. Outcomes were intra-rater repeatability, inter-rater reproducibility and inter-session reproducibility using intra-class correlation coefficients (ICC). Limits of agreement and weighted least products regression were used to test the validity of the LSMD relative to the criterion standard (IKD), and calibration formulas derived to improve measurement fidelity. ICC values for the LSMD were >0.90 for all measures of reliability and for both muscle groups, but over-predicted extensor strength and under-predicted flexor strength. Validity was established by transforming the data with the criterion standard-based calibration. These data indicate that the LSMD is reliable and conditionally valid for quantifying strength of elbow flexors and extensors in a healthy adult population.

“…36 Ada et al 5 followed individuals with stroke up to one year and concluded that spasticity can cause contracture. However, the work by McGibbon et al 37 in traumatic brain injury, spinal cord injury and cerebral palsy suggests that there is not a clear association between spasticity and contracture.…”

Prevalence of unmet needs for spasticity management in care home residents in the East Midlands, United Kingdom: a cross-sectional observational study

Objective: To establish the prevalence of unmet need for spasticity management in care home residents in two counties of the United Kingdom. Design: Cross-sectional observational study with a six-month follow-up arm for participants with identified unmet needs. Setting: 22 care homes in Derbyshire and Nottinghamshire. Subjects: 60 care home residents with upper motor neuron syndrome–related spasticity. Interventions: No intervention. When unmet needs around spasticity management were identified, the participant’s general practitioner was advised of these in writing. Main measures: Resistance to Passive Movement Scale to assess spasticity; recording of (a) the presence of factors which may aggravate spasticity, (b) potential complications of spasticity, (c) spasticity-related needs and (d) current interventions to manage spasticity. Two assessors judged the presence or absence of needs for spasticity management and whether these needs were met by current care. Results: Out of 60 participants, 14 had no spasticity-related needs; 46 had spasticity-related needs; 11 had needs which were being met by current care and 35 participants had spasticity-related needs at baseline which were not being met by their current care. These were most frequently related to the risk of contracture development or problems with skin hygiene or integrity in the upper limb. In total, 6 participants had one or more pressure sores and 35 participants had one or more established joint contractures. A total of 31 participants were available for follow-up. Informing general practitioners of unmet needs resulted in no change to spasticity management in 23/31 cases. Conclusion: Care home residents in this study had high levels of unmet need for spasticity management.

Evaluation of a toolkit for standardizing clinical measures of muscle tone

Abstract: The BioTone toolkit provided comprehensive objective measures for assessing muscle tone in patients with UMNS. The toolkit could be useful for standardizing outcomes measures in clinical trials and for routine practice.
