Study Design: Technical note. Objectives: To provide spine surgeons new to telemedicine with a structured physical examination technique based on manual motor testing principles. Methods: Expert experience describing a series of specific maneuvers for upper and lower extremity strength testing that can be performed using a telemedicine platform. In addition, we offer instruction on “setting up” for these visits and highlight special tests that can be used to diagnose specific cervical and lumbar spine conditions. Results: From our experiences in conducting telemedicine visits, we provide a means of testing and scoring upper and lower extremity strength for interpretation of weakness in the context of traditional manual motor testing. Also, we acknowledge the limitations of a remote examination and discuss maneuvers that cannot be performed remotely. Conclusions: COVID-19 has drastically altered the delivery of care for patients with spine-related complaints. The need for social distancing has led to the widespread adoption of telemedicine. This technical note provides an urgently needed framework for the standardization of the remote physical exam. Validation of the exam as a diagnostic tool will be a crucial next step in studying the impact of telemedicine.

The Impact

4615 Background: Although prolonged use ofADT is hypothesized to adversely affect physical function, only a few small studies have examined this relationship and it remains unclear if self-reported weakness represents a decline in actual physical performance or is related to fatigue. Loss of physical function may be particularly important to older men who already have limited functional reserves. Methods: Men age 50 or older with non-metastatic prostate cancer who were starting continuous ADT were enrolled in this prospective longitudinal study. Physical function was tested using a Jamar dynamometer (grip strength), the Timed Up and Go (TUG) test, and the six-minute walk test (6MWT), representing upper extremity strength, lower extremity strength, and endurance, respectively. Assessments were done at baseline (prior to ADT), 3 months, 6 months, and 12 months. Results: 42 patients on ADT have been enrolled to date (mean age 74.8 y). There was a gradual but steady decline in grip strength from baseline (39.2 kg) to 3 months (38.1 kg), 6 months (37.9 kg), and 12 months (35.3 kg) (p < 0.05 for all comparisons). On average, patients took 7.3 seconds to complete the TUG and walked 1507 feet during the 6MWT at baseline. TUG and 6MWT scores did not worsen over time (p > 0.05). Conclusions: Preliminary data suggest that 3–12 months of ADT is associated with worsening upper extremity strength but lower extremity strength and endurance are relatively unaffected. A larger sample size is needed to determine if all aspects of physical function or only upper extremity strength deteriorate with ADT use. Additionally, most patients in our study reported excellent health and functional status at baseline and our results may not adequately reflect the impact of ADT in more frail older men.

The Impact

This study evaluated the feasibility and effectiveness of translating the evidence-based program, Fit & Strong!, into a Spanish program, ¡En Forma y Fuerte!. A single-group, quasi-experimental design (n = 34, mean age = 58.8 [8.1], 87.2% female, 87.2% reported speaking mostly Spanish) was used to assess implementation feasibility and the impact of ¡En Forma y Fuerte! on arthritis-related outcomes in Hispanics with arthritis. Significant improvements in lower-extremity strength, perceived physical function, and pain were observed from baseline to 8 weeks (p < .05); these improvements were maintained at 6 months. Significant improvements in aerobic endurance and stiffness were observed from baseline to 6 months (p < .05). No major program adaptations (other than language) were observed or reported. However, the instructors provided several suggestions for program improvements, including adjusting the literacy level and length of the program. Findings suggest ¡En Forma y Fuerte! is feasible and effective, potentially providing a much-needed program for older Hispanics with arthritis.

Abstract Prior studies link specific sleep parameters to physical functioning in older adults. Recent work suggests the utility of examining sleep health from a multidimensional perspective, enabling consideration of an individual’s experience across multiple different sleep parameters (e.g., quality, duration, timing). We examined the associations of multidimensional sleep health with objective, performance-based measures of physical functioning in older adults. We conducted a secondary analysis of 158 adults (Mage=71.8 years; 51.9% female) who participated in the Midlife in the United States (MIDUS) 2 and MIDUS Refresher studies. We used data from daily diaries, wrist actigraphy, and self-report measures to derive a composite multidimensional sleep health score ranging from 0-6, with higher scores indicating better sleep health. Physical function was assessed using gait speed during a 50-foot timed walk, lower extremity strength as measured by a chair stand test, and grip strength assessed with dynamometers. We used hierarchical regression to examine the associations between sleep health and gait speed, lower extremity strength, and grip strength. Age, sex, race, education, depression symptoms, medical comorbidity, and body mass index were covariates in each model. In adjusted analyses, better multidimensional sleep health was significantly associated with faster gait speed (B=.03, p=.01). Multidimensional sleep health was not significantly associated with lower limb strength (B=-.12, p=.89) or grip strength (B=.45, p=.40). Gait speed is a key indicator of functional capacity as well as morbidity and mortality in older adults. Multidimensional sleep health may be a therapeutic target for improving physical functioning and health in older adults.

The Impact

Background: Occupational footwear and a prolonged duration of walking have been previously reported to play a role in maintaining postural stability. The purpose of this paper was to analyze the impact of three types of occupational footwear: the steel-toed work boot (ST), the tactical work boot (TB), and the low-top work shoe (LT) on previously unreported lower extremity muscle activity during postural stability tasks. Methods: Electromyography (EMG) muscle activity was measured from four lower extremity muscles (vastus medialis (VM), medial hamstrings (MH), tibialis anterior (TA), and medial gastrocnemius (MG) during maximal voluntary isometric contractions (MVIC) and during a sensory organization test (SOT) every 30 min over a 4 h simulated workload while wearing ST, TB, and LT footwear. The mean MVIC and the mean and percentage MVIC during each SOT condition from each muscle was analyzed individually using a repeated measures ANOVA at an alpha level of 0.05. Results: Significant differences (p < 0.05) were found for maximal exertions, but this was limited to only the time main effect. No significant differences existed for EMG measures during the SOT. Conclusion: The findings suggest that occupational footwear type does not influence lower extremity muscle activity during both MVIC and SOT. Significantly lower muscle activity during maximal exertions over the course of the 4 h workload was evident, which can be attributed to localized muscular fatigue, but this was not sufficient to impact muscle activity during postural stability tasks.

Lower Extremity Strength

The traditional method for normalizing quantitative strength data is to divide force or torque by body mass. We have previously shown that this method is not appropriate for able-bodied children and young adults and that normalization using allometric scaling is more effective. The purpose of the current study was to evaluate the effectiveness of applying existing normalization equations for lower extremity strength to children, adolescents, and young adults with cerebral palsy (CP) and, if appropriate, to develop CP-specific normalization equations using allometric scaling. We measured the maximum torque generated during hip abduction/adduction, knee extension/flexion, and ankle dorsiflexion/plantar flexion in 96 subjects with spastic diplegia CP ages 4–23 years. Traditional mass normalization (Torque/Mass1.0) and allometric scaling equations from children without disability (Torque/Mass1.6for hip and knee; Torque/Mass1.4for ankle) were not effective in eliminating the influence of body mass. Normalization using CP-specific allometric scaling equations was effective using both muscle-specific and common (Torque/Mass0.8for ankle plantar flexors; Torque/Mass1.4for all others) scaling relationships. For the first time, normalization equations have been presented with demonstrated effectiveness in adjusting strength measures for body size in a group of children, adolescents, and young adults with CP.
