The rising importance of movement analysis led to the development of more complex
biomechanical models to describe in detail the human motion patterns. The models scaled …

Spasticity, a common symptom in patients with upper motor neuron lesions, reduces the
ability of a person to freely move their limbs by generating unwanted reflexes. Spasticity can …

Background. There is no easy and reliable method to measure spasticity, although it is a
common and important symptom after a brain injury. Objective. The aim of this study was to …

Although rigidity is a cardinal motor sign in patients with Parkinson's disease (PD), the
instrumental measurement of this clinical phenomenon is largely lacking, and its …

This paper presents the framework for developing a robotic system to improve accuracy and
reliability of clinical assessment. Clinical assessment of spasticity tends to have poor …

Introduction: Differentiating between the components of wrist hyper-resistance post stroke,
ie, pathological neuromuscular activation (“spasticity”) and non-neural biomechanical …

Quantifying neural and non-neural contributions to increased joint resistance in spasticity is
essential for a better understanding of its pathophysiological mechanisms and evaluating …

Patients with poor upper limb motor recovery after stroke are likely to develop increased
resistance to passive wrist extension, ie, wrist hyper-resistance. Quantification of the …

We sought to determine the relative velocity sensitivity of stretch reflex threshold angle and
reflex stiffness during stretches of the paretic elbow joint in individuals with chronic …

Existing studies lack a clear understanding of the interaction of the joint capsule with
surrounding tissues and the local mechanical environment. Particularly, a finite element …
