[0115] method

[0116] Subject:

[0117] Ten adult stroke patients were recruited in the rehabilitation clinic of the Sainte-Anne Hospital in Paris. All patients had a single ischemic or hemorrhagic stroke and were enrolled in the study for at least 2 weeks after the stroke. Includes patients with varying degrees of hemiplegia affecting the upper limbs and hands. Exclusion criteria included severe loss of sensation in the affected limb, other neurological conditions that would interfere with the interpretation of the experiment, and other cognitive impairments such as visual impairment or severe neglect. Ten age-matched healthy control subjects were also recruited. Table 1 lists demographic and clinical details. The study procedures complied with the Declaration of Helsinki and informed consent was provided to the subjects.

Abstract

The present invention relates to a new method for quantifying key components of manual dexterity. The present invention also provides methods for diagnosing impaired upper limb and / or hand function inpatients based on how these components are affected.

Description

Background technique [0001] High manual dexterity is a central feature of the human upper limb. The rich interplay of sensory and motor components in the hand and fingers allows independent control of the fingers in terms of timing, kinematics, and force. [0002] Manual dexterity enables fine control in grasping and manipulating small objects. Among species, manual dexterity has evolved most in humans [1]. This high degree of manual dexterity is made possible by specialization in hand morphology (bones, muscles) and neural control (corticospinal tracts) [2]. Together, these specializations allow for purposeful goal-oriented and object-oriented manual control. However, there is no consensus on how to operationally define and quantify flexibility. Although an "index of dexterity" has been developed historically (mainly for phylogenetic considerations [3]), it has become clear that behavioral flexibility cannot be defined by a single variable. Therefore, several studies hav...
