Brief Summary:
It is unclear why humans typically swing their arms during gait To date the debate on how to arm swing comes about ie whether it is caused by accelerations of the shoulder girdle or muscular activity is still going on There needs to be consensus on whether the arm swing is actively controlled or merely passive and on why humans swing their arms during walking ie what the purpose of arm swing is if any Suggested reasons include minimising energy consumption optimising stability and optimising neural control Pathologies such as hemiplegia after stroke Parkinsons disease Cerebral Palsy Spinal Cord Injury and Multiple Sclerosis may directly affect arm swing during gait Emerging evidence indicates that including arm movements in gait rehabilitation may be beneficial in restoring interlimb coordination and decreasing energy expenditure
This project hypothesises that the arms swing at least at low and intermediate walking speeds reflects the bodys Center of Mass CoM accelerations Arm swing may thus depend mainly upon the systems intrinsic mechanical properties eg gravity and inertia In this perspective the CoM is seen as moving relative to the upper limbs rather than the other way around The contribution of major lower limb joints in terms of power injected into the body motion will be simultaneously explored
The study aims to investigate the mechanism and functions of arm swinging during walking on a force treadmill To simulate asymmetric walking healthy subjects will be asked to walk with a toes-up orthosis to induce claudication and asymmetry in ankle power In this way it will be possible to highlight the correlation among arm swinging ankle power and the acceleration of the CoM in a 3D framework In addition subjects affected by unilateral motor impairments will be asked to walk on the force treadmill to test the experimental model and highlight significant differences in the kinematic parameters of the upper limbs
The question of whether arm swing is actively controlled or merely passive and the relationship between arm swinging and the total mechanical energy of the CoM will be faced
Asymmetric oscillations of the upper limb will be related to dynamic asymmetries of the COM motion and of the motion of lower limbs In addition cause-effect relationships will be hypothesized Finally the dynamic correlates of upper limb oscillations will make the clinical observation an interpretable clinical sign applicable to rehabilitation medicine
Results from the present study will also foster the identification of practical rehabilitation exercises on gait asymmetries in many human nervous diseases
