“…Some studies report body mass as the strongest correlate with muscle strength in children, [8][9][10][11] while others demonstrate as we did that height showed the strongest relationship and was the most significant predictor of strength. 23,24 In adults, a decline in strength was most strongly associated with aging in 5 muscle groups (hand grip, ankle dorsiflexors, shoulder external rotators, knee flexors, and extensors), while in older adulthood all muscle groups demonstrated a significant decline in strength associated with aging. These results suggest a musclespecific response to aging during adulthood and that generalized weakness does not occur until older adulthood.…”

Objective: To establish reference values for isometric strength of 12 muscle groups and flexibility of 13 joint movements in 1,000 children and adults and investigate the influence of demographic and anthropometric factors.Methods: A standardized reliable protocol of hand-held and fixed dynamometry for isometric strength of ankle, knee, hip, elbow, and shoulder musculature as well as goniometry for flexibility of the ankle, knee, hip, elbow, shoulder, and cervical spine was performed in an observational study investigating 1,000 healthy male and female participants aged 3-101 years. Correlation and multiple regression analyses were performed to identify factors independently associated with strength and flexibility of children, adolescents, adults, and older adults. Results:Normative reference values of 25 strength and flexibility measures were generated.Strong linear correlations between age and strength were identified in the first 2 decades of life. Muscle strength significantly decreased with age in older adults. Regression modeling identified increasing height as the most significant predictor of strength in children, higher body mass in adolescents, and male sex in adults and older adults. Joint flexibility gradually decreased with age, with little sex difference. Waist circumference was a significant predictor of variability in joint flexibility in adolescents, adults, and older adults. Conclusions:Reference values and associated age-and sex-stratified z scores generated from this study can be used to determine the presence and extent of impairments associated with neuromuscular and other neurologic disorders, monitor disease progression over time in natural history studies, and evaluate the effect of new treatments in clinical trials. Neurology ® 2017;88:36-43Meaningful, reliable, and sensitive outcome measures are required to monitor treatment and progression of neuromuscular and other neurologic disorders. While there have been substantial advances in the understanding of the pathogenesis and natural history of many neuromuscular disorders, the identification and development of new outcome measures that best reflect the efficacy of specific treatments have not advanced at the same rate. 1 Establishing valid and responsive outcome measures is a priority for the field. 2 To assist in the development of new outcome measures, normative reference values generated from large populations across the lifespan using standardized methods are required. Normative reference values can be utilized to generate z scores, which can be used in multicenter studies to improve outcome measure precision and responsiveness.Muscle weakness and joint contractures predispose to numerous pathologies requiring intervention. Reference data play an important role in identifying and quantifying these impairments and evaluating the effectiveness of interventions. Currently, few comprehensive datasets detail the normal variation of active range of motion in healthy individuals and are limited by the number of joints assessed, 3...

“…The association between height and strength in children, which we also observed in our samples, is an important phenomenon and one that is thought to explain much of the differences in strength between similarly aged children. 32 As we had no measure of maturity, we are unable to speculate as to how it contributes to between-country differences in strength per se, or its potential mediating effect via greater height.…”

“…One method to minimize the confounding factors of growth and maturation would be to express strength values as a percentage of predicted values based on normative data. Stature is a major predictive factor of muscle strength, 29 but methods for an accurate estimate of stature may be Figure 2 Correlations between grip strength and nuclear magnetic resonance variables…”

Objective: To explore the value of nuclear magnetic resonance (NMR) and functional assessments for follow-up of ambulatory and nonambulatory patients with Duchenne muscular dystrophy (DMD).Methods: Twenty-five 53-skippable patients with DMD were included in this study; 15 were nonambulatory at baseline. All patients underwent clinical and functional assessments every 6 months using the Motor Function Measure (MFM), hand grip and key pinch strength, MoviPlate, and NMR spectroscopy and imaging studies.Results: Upper limb distal strength decreased in nonambulatory patients over the period of 1 year; ambulatory patients showed improvement during the same period. The same applied for several NMRS indices, such as phosphocreatine/adenosine triphosphate, which decreased in older patients but increased in younger ambulatory patients. Fat infiltration in the upper limbs increased linearly with age. Almost all NMR and functional assessment results correlated. Conclusions:Our results underscore complementarity of functional and NMR assessments in patients with DMD. Sensitivity to change of various indices may differ according to disease stage. MFM 5 Motor Function Measure; NMR 5 nuclear magnetic resonance; NMRI 5 nuclear magnetic resonance imaging; NMRS 5 nuclear magnetic resonance spectroscopy; PCr 5 phosphocreatine; Pi 5 inorganic phosphate; Pia 5 cytosolic inorganic phosphate; Pib 5 anomalous alkaline pool present in dystrophic muscle; PDE 5 phosphodiester; PME 5 phosphomonoester; TR 5 repetition time.
