The Effect of Foot Orthosis on the Vertical Component of the Ground Reaction Force While Walking: A Review Study
Objective: Every person is required to walk and stand for long periods of time during daily activities, especially at work, as a result of which ground reaction force to the parts and joints is very high, and these forces sometimes reach several times the body weight in the foot and the ankle foot can have devastating effects. Various studies have suggested different methods and factors for red...
متن کاملForce treadmill for measuring vertical and horizontal ground reaction forces.
We constructed a force treadmill to measure the vertical, horizontal and lateral components of the ground-reaction forces (Fz, Fy, Fx, respectively) and the ground-reaction force moments (Mz, My, Mx), respectively exerted by walking and running humans. The chassis of a custom-built, lightweight (90 kg), mechanically stiff treadmill was supported along its length by a large commercial force plat...
متن کاملAgreement between vertical ground reaction force and ground reaction force vector in five common clinical tests.
Mechanography is an innovative method to evaluate lower-limb dynamic muscle function. This technique is generally performed on force platforms that measure only the vertical component of ground reaction force (GRF). The underlying assumption is that medio-lateral and antero-posterior forces do not contribute significantly to the GRF in jumping and rising tests. The goal of this study was to est...
متن کاملCorrelation between ground reaction force and tibial acceleration in vertical jumping.
Modern electronics allow for the unobtrusive measurement of accelerations outside the laboratory using wireless sensor nodes. The ability to accurately measure joint accelerations under unrestricted conditions, and to correlate them with jump height and landing force, could provide important data to better understand joint mechanics subject to real-life conditions. This study investigates the c...
متن کاملEvaluation of vertical ground reaction force during walking in patients with multiple sclerosis
Patients with Multiple Sclerosis (MS) suffer from inabilities such as weakness and muscle fatigue due to the demyelination. The inabilities may result in some disorders in walking. The present study is a clinical trial research conducted on 84 participants in two groups of experimental and control who were randomly selected. The results showed that people with MS apply more force on the ground ...
