Abstract
Background
While leg stiffness during running has been shown to be lower in children with cerebral palsy compared to their typically developing peers, no studies have examined leg stiffness during running in adults with traumatic brain injury. The aim of this study was to compare leg stiffness during running in adults with traumatic brain injury to healthy controls.
Methods
Sixty-one adults with traumatic brain injury and 20 healthy controls were included. Participants ran overground while three-dimensional kinematic and kinetic data were recorded. Leg stiffness was calculated during the stance phase of running. Statistical analyses to compare leg stiffness between limbs and between groups were conducted using t-tests.
Findings
There was a large range of leg stiffness in adults with traumatic brain injury during running (affected leg median = 21.56 [range 11.07 to 57.44] kN/m; less affected leg =20.87 [9.38 to 54.72] kN/m) compared to healthy controls (20.94 [13.40 to 31.50] kN/m). However, there were no statistically significant differences in leg stiffness during running between the affected and less affected limbs (p = 0.59, effect size [ES] =0.08) nor between both traumatic brain injury limbs and healthy controls (affected limb; p = 0.44, ES =0.12; less affected limb; p = 0.47, ES =0.11).
Interpretation
Although no statistical significance was found on a group level, the results demonstrated high variability in leg stiffness in traumatic brain injury compared to healthy controls. Further research is needed to determine which factors influence leg stiffness during running and how this measure relates to clinical outcomes in traumatic brain injury.
期刊介绍：
Clinical Biomechanics is an international multidisciplinary journal of biomechanics with a focus on medical and clinical applications of new knowledge in the field.
The science of biomechanics helps explain the causes of cell, tissue, organ and body system disorders, and supports clinicians in the diagnosis, prognosis and evaluation of treatment methods and technologies. Clinical Biomechanics aims to strengthen the links between laboratory and clinic by publishing cutting-edge biomechanics research which helps to explain the causes of injury and disease, and which provides evidence contributing to improved clinical management.
A rigorous peer review system is employed and every attempt is made to process and publish top-quality papers promptly.
Clinical Biomechanics explores all facets of body system, organ, tissue and cell biomechanics, with an emphasis on medical and clinical applications of the basic science aspects. The role of basic science is therefore recognized in a medical or clinical context. The readership of the journal closely reflects its multi-disciplinary contents, being a balance of scientists, engineers and clinicians.
The contents are in the form of research papers, brief reports, review papers and correspondence, whilst special interest issues and supplements are published from time to time.
Disciplines covered include biomechanics and mechanobiology at all scales, bioengineering and use of tissue engineering and biomaterials for clinical applications, biophysics, as well as biomechanical aspects of medical robotics, ergonomics, physical and occupational therapeutics and rehabilitation.
