BACKGROUND Identifying highly sensitive and reliable neurological exam components are crucial in recognizing clinical deficiencies. This study aimed to investigate finger tapping performance differences between patients with CNS demyelinating lesions and healthy control subjects. METHODS Twenty-three patients with multiple sclerosis or clinically isolated syndrome with infratentorial and/or c...

Finger-thumb coordination is crucial to manual dexterity but remains incompletely understood, particularly following neurological injury such as stroke. While being controlled independently, the index finger and thumb especially must work in concert to perform a variety of tasks requiring lateral or palmar pinch. The impact of stroke on this functionally critical sensorimotor control during dyn...

We consider the problem of impedance control for the physical interaction between the soft tip of a robot finger, where the nonlinear characteristics of the reproducing force and the finger dynamic parameters are unknown, and a rigid object or environment under kinematic uncertainties arising from both uncertain contact point location and uncertain rigid object geometry. An adaptive controller ...

severity of RP and improvement in scleroderma health assessment questionnaire (SSc HAQ). Endothelial function was assessed by measuring the flow mediated dilatation and soluble markers of endothelial function. Results: Twenty four of 25 recruited patients completed the study. There were 20 females. The mean age was 36.71 8.43 years and mean disease duration was 6.7 4.3 years. All the patients w...

Several studies in the past have demonstrated a strong correlation of finger lengths ratio and human personality. This current prospective study attempts to correlate the finger length ratio of the 4 to 5 finger in males and females with the human personality traits --Psychoticism, Neuroticism & Extraversion using EPQ (Eysenck Personality Questionnaire). The hypothesis in this study is that mal...

Nowadays, with increasing the injuries to hand, specially fingers, because of saving in time and money, wearable robots are so practical use order rehabilitate injured part body. This exoskeleton is designed thumb do opposition movement, which one DOF (degree freedom) a passive type cable mechanism. These cables placed by two drums, on other tip assistive finger, have adjusting screw that can b...

There are different biometric modalities used to identify person which includes palmprint, face, fingerprint, iris and hand geometry. Apart from these biometric modalities, finger knuckle print also used as one of the cost effective biometric identifier. Finger knuckle print is defined by the back side of fingers. On the back side of fingers there are three joints named as Metacarpophalangeal (...

We analyzed the adaptability of human thumb and index finger movement kinematics and dynamics to variations of precision grip aperture and movement velocity. Six subjects performed precision grip opening and closing movements under different conditions of movement velocity and movement aperture (thumb and index finger tip-to-tip distance). Angular motion of the thumb and index finger joints was...

Hand gesture recognition system can be used for human-computer interaction (HCI). Proper hand segmentation from the background and other body parts of the video is the primary requirement for the design of a hand-gesture based application. These video frames can be captured from a low cost webcam (camera) for use in a vision based gesture recognition technique. This paper discusses about the co...
