Section I. Notice of Funding Opportunity Description

Background

Mobility dysfunction affects >25% of the population over 65 years of age, and thus constitutes a major public health problem. Older adults walk more slowly and with elevated metabolic cost (mass-specific energy cost per unit distance traveled), factors that severely limit their independence, activities of daily living, and quality of life. A higher energy cost of walking is proposed as a risk factor for developing slowed gait speed and reduced mobility in old age. However, the mechanisms for this association between gait speed and energy cost are not yet understood, nor consequently have versatile and effective interventions to mitigate this problem been fully developed. The significant societal, economic, and personal burdens associated with mobility limitations highlight the importance of understanding the mechanisms for increased metabolic cost of walking and slowed walking speed with aging.

Changes in old age that contribute to the complex issue of an increased metabolic cost of walking in older adults appear to center at least in part on changes in gait biomechanics. Neuromuscular system changes, including altered muscle strength/power, bioenergetics, balance, and joint mobility, are thought to contribute to a reduction in mobility by impacting gait biomechanics. While the precise mechanisms for neuromuscular system changes and decreased mobility remain unclear, it is hypothesized that gait impairments or changes in gait associated with the aging neuromuscular system play an important role in the functional limitations affecting older adults. 

A prevailing concept in the field of gait biomechanics is that there is a “distal-to-proximal shift” in muscle workloads with advancing age such that older adults move away from an “ankle strategy” toward a “hip strategy” for producing propulsion and support during walking. The greater reliance on hip muscles for walking in older adults is a compensatory mechanism that prevents or delays the functional consequences of age-related physiological abnormalities. However, this strategy of compensation was found to be a significant predictor of the greater metabolic cost of walking in older as compared to younger adults. Moreover, the mechanisms behind the walking strategies that compensate for the redistribution in hip and ankle joint movements, peak ankle moments, and power generation with aging remain unclear. In addition, there are limited data for how activation patterns of specific muscle and muscle groups change with age and contribute to gait changes.

While muscle strength (i.e., maximal voluntary torque) is likely to play some role in the alteration of gait with age, looking beyond muscle strength alone to evaluate the impact of changes in structure, composition, and morphology of muscle and tendon; contraction velocity and power; neural drive to muscle; and interactions among these systems may yield more insight about the mechanisms of age-related changes in gait mechanics. Tendons work in concert with muscles; therefore, the entire muscle-tendon complex should be considered when exploring the mechanisms for changes in gait biomechanics with aging, and their consequences on the metabolic cost of walking. In addition to the tendon itself, the extracellular matrix (ECM) is an important, although understudied, component of skeletal muscle. The ECM plays a role in force transmission, passive force development, muscle shape changes, gearing, and mechanotransduction. Therefore, a better understanding of how ECM changes in aging constitutes a significant opportunity for improving gait and reducing its energy cost in the older population.

A critical barrier to effective targeting of prevention and rehabilitation strategies is the lack of understanding at multiple levels of the impact of age-related changes in the neuromuscular system combined with molecular mechanisms in skeletal muscle to directly impact mobility function and fatigue in older individuals. Skeletal muscle energetics are particularly important in this regard. Abnormalities of gait and changes in posture during walking raise the metabolic costs of walking, which is associated with alterations in muscle bioenergetics at the cellular level. Many compensatory strategies aimed at maintaining mobility and physical function in general lead to a reduction in physiologic reserve that may play a significant role in the pathogenesis of fatigue. Therefore, a combination of neuromuscular impairments, muscle bioenergetic abnormalities, and compensatory gait and posture strategies all contribute to slower walking speed, increased metabolic cost of walking, and increased fatigability that are observed with aging. However, the mechanisms by which these factors affect gait speed, metabolic cost of walking, and fatigability are not well understood.

To this end, the Division of Geriatrics and Clinical Gerontology convened a workshop titled “Causes & Consequences of Age-Related Changes in Gait Biomechanics: The Metabolic Cost of Walking” on September 20-21, 2021. The goal of this  workshop was to identify promising ways to move the field forward toward improving gait performance, decreasing energy cost, and enhancing mobility for older adults. Key gaps in the literature that warrant targeted research are identified and discussed in t he  workshop report.

Purpose and Objectives

This NOFO invites R01 applications that propose new clinical research studies to better understand the mechanisms underlying compensatory gait, posture, and molecular changes that contribute to slower walking speed and increased metabolic cost of walking. This NOFO encourages interdisciplinary collaborations to design integrative approaches that explore interactions among multiple systems (e.g., skeletal, muscle, tendon, somatosensory, and central nervous). This NOFO also encourages innovative approaches such as computational modeling, imaging, sensor technologies, machine learning, and artificial intelligence to disentangle compensatory gait alterations with aging that contribute to increased metabolic cost of walking and fatigue. Areas of interest include: 

  1. Mechanisms and effects of central nervous system changes 
  2. Mechanisms and effects of neuromuscular changes 
  3. Skeletal muscle bioenergetics
  4. Computational modeling and simulation
  5. Changes in tissue structure and function (e.g., muscle-tendon complex)

To optimally target and ameliorate age-related changes in gait biomechanics and their effects on the metabolic cost of walking, the specific mechanisms underlying these changes need to be understood. The aging human neuromuscular system undergoes normative changes beyond loss of muscle mass and strength that may also contribute to reduced mobility. Therefore, the complexity of the problem requires looking beyond muscle strength alone to the changes in structure, composition, and morphology of muscle, tendon, and the ECM; alterations in neural drive to muscle; biomechanics kinetics and kinematics; and skeletal muscle bioenergetics. Moreover, exploring the interactions of these factors may yield insights into the mechanisms for age related changes in gait mechanics and increased metabolic cost of walking. Therefore,  questions to be addressed through this NOFO include, but are not limited to, the following:

  • How do neuromuscular changes (e.g., cortical excitability, motor unit firing rates, sensory function [neural feedback], rate of force production) alter gait biomechanics and metabolic cost of walking in older adults?
  • How do neuromuscular changes impact skeletal muscle function and bioenergetics to increase metabolic cost of walking in older adults?
  • How do physical activity/sedentariness, sex, medication use, and comorbid conditions moderate the effects of aging on bioenergetic capacity and neural pathway function/drive in skeletal muscle?
  • How do prolonged muscle activation (e.g., more co-contraction) or different patterns of muscle activation affect efficiency of power generation by muscle-tendon units and impair underlying cellular metabolic processes to alter muscle mechanics, gait, and metabolic cost of walking?
  • How can computer simulation modeling be used to identify which age-related changes in the neuromusculoskeletal system (e.g., reduced contraction speed) are most responsible for changes in gait performance (e.g., reduced gait speed) and biological changes in muscle?
  • How do muscle weakness and fat accumulation and distribution play a role in altered gait mechanics and the cost of walking in old age?
  • How do reduced muscle mass, altered bioenergetics, or an inability to optimally activate muscle play a role in altered gait mechanics and the cost of walking in old age?
  • How does degradation of the sensory system that leads to deficits in proprioception, vestibular sensing, and cutaneous sensing play a role in altered gait mechanics and the cost of walking in old age?
  • How do changes in tissue structure and function (e.g., muscle-tendon complex, extracellular matrix) play a role in altered gait mechanics and the cost of walking in old age?

Section V. Application Review Information

1. Criteria

Only the review criteria described below will be considered in the review process.  Applications submitted to the NIH in support of the NIH mission are evaluated for scientific and technical merit through the NIH peer review system.

A proposed Clinical Trial application may include study design, methods, and intervention that are not by themselves innovative but address important questions or unmet needs. Additionally, the results of the clinical trial may indicate that further clinical development of the intervention is unwarranted or lead to new avenues of scientific investigation.

Overall Impact

Reviewers will provide an overall impact score to reflect their assessment of the likelihood for the project to exert a sustained, powerful influence on the research field(s) involved, in consideration of the following review criteria and additional review criteria (as applicable for the project proposed).

Scored Review Criteria

Reviewers will consider each of the review criteria below in the determination of scientific merit and give a separate score for each. An application does not need to be strong in all categories to be judged likely to have major scientific impact. For example, a project that by its nature is not innovative may be essential to advance a field.

 

Does the project address an important problem or a critical barrier to progress in the field? Is the prior research that serves as the key support for the proposed project rigorous? If the aims of the project are achieved, how will scientific knowledge, technical capability, and/or clinical practice be improved?
