“…A subgroup of 25 healthy individuals from the 1000 Norms Project aged between 15 and 74 years volunteered for plantarflexion strength testing using both the HHD alone and HHD with the fixation device. The 1000 Norms Project has collected a wide range of performance outcome measures throughout the lifespan from 1,000 individuals to identify the range of “normal” variation in the healthy population.…”

“…Data were collected as part of the 1,000 Norms Project, an observational study investigating physical function and self-reported health in 1,000 people across the lifespan (see full protocol 20 ). One thousand people aged between 3 and 101 years from the Greater Sydney metropolitan area in Australia participated in the project.…”

“…20 The dominant limb was assessed and determined as the hand used to write with and the foot used to kick a ball. The strength of 12 muscle groups-hand grip, ankle dorsiflexors and plantarflexors, knee flexors and extensors, hip abductors, internal and external rotators, elbow flexors and extensors, and shoulder internal and external rotators-were assessed by maximal voluntary isometric contraction using a portable hand-held dynamometer (Citec dynamometer CT 3001; CIT Technics, Groningen, Netherlands).…”

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...

“…This effort can be seen in studies such as the 1000 Norms Project, which aims to establish for physiotherapists what a "normal" range is in "healthy" humans in the areas of dexterity, balance, ambulation, joint range of motion, strength, endurance and motor planning (McKay et al, 2016). Looking at power from a Foucauldian perspective, considering who constructs what constitutes "normal" is very important, as these people have the power to decide who/what needs intervention (disciplining) to become more "normal".…”
