Knowledge on joint impedance during walking in various conditions is relevant for clinical
decision-making and the development of robotic gait trainers, leg prostheses, leg orthotics and …

In vivo joint stiffness estimation during time-varying conditions remains an open challenge.
Multiple communities, eg system identification and biomechanics, have tackled the problem …

Joint stiffness estimation under dynamic conditions still remains a challenge. Current stiffness
estimation methods often rely on the external perturbation of the joint. In this study, a novel '…

An important goal in the design of next-generation exoskeletons and limb prostheses is to
replicate human limb dynamics. Joint impedance determines the dynamic relation between …

Motorized assessment of the stretch reflex is instrumental to gain understanding of the
stretch reflex, its physiological origin and to differentiate effects of neurological disorders, like …

Background Spasticity, ie stretch hyperreflexia, increases joint resistance similar to symptoms
like hypertonia and contractures. Botulinum neurotoxin-A (BoNT-A) injections are a widely …

Background People with brain or neural injuries, such as cerebral palsy or spinal cord injury,
commonly have joint hyper-resistance. Diagnosis and treatment of joint hyper-resistance is …

Ahstract- Biofeedback of online system identification estimates of intrinsic and reflexive joint
impedance can be used by able-bodied subjects to voluntarily modulate their reflexive …

People with spasticity, ie, stretch hyperreflexia, have a limited functional independence and
mobility. While a broad range of spasticity treatments is available, many treatments are …

BEFoRE the 1990s, the design of almost all flight control laws for aircraft was based on
classical control techniques. 1, 2 However, in recent years the use of advanced, multivariable …
