In this study, we investigate in children the neural underpinnings of finger representation and finger movement involved in single-digit arithmetic problems. Evidence suggests that finger representation and finger-based strategies play an important role in learning and understanding arithmetic. Because different operations rely on different networks, we compared activation for subtraction and m...

Finger rehabilitation robots are developed to assist therapists in performing processes on patients. The repetitive flexion and extension have shown positive outcome improving functionality of fingers among post-stroke However, these made rigid structures actuators such as pulleys motors which pose danger the delicate human fingers. This paper proposes a bidirectional bending fibre-reinforced s...

Finger-vein recognition has received increased attention recently. However, the finger-vein images are always captured in poor quality. This certainly makes finger-vein feature representation unreliable, and further impairs the accuracy of finger-vein recognition. In this paper, we first give an analysis of the intrinsic factors causing finger-vein image degradation, and then propose a simple b...

In this paper, we propose a new finger multi-biometric cryptosystem using feature-level fusion to simultaneously protect multiple templates of fingerprint, finger vein, finger knuckle print and finger shape traits as a single secure sketch. We theoretically analyze the featurelevel fusion for finger multi-biometric cryptosystem with respect to their impact on security and recognition accuracy. ...

The Bogus Finger is a remote-controllable tool for simulating vertical pressing forces of various magnitude as exerted by human finger. Its main application the characterization haptic devices under realistic active touch conditions. device released an open-source hardware and software DIY project that can be easily built using off-the-shelf components. We report quasi-static properties device,...

Most trigger digit (TD) patients complain that they have problems using their hand in daily or occupational tasks due to single or multiple digits being affected. Unfortunately, clinicians do not know much about how this disease affects the subtle force coordination among digits during manipulation. Thus, this study examined the differences in force patterns during cylindrical grasp between TD ...

The measurement of volume pulse waves may be easily affected based on the measured position (different fingers or toes), body posture, as well as other factors. Therefore, interferences during measurement need to be removed. For this study, relevant parameters of volume pulse wave were obtained by changing the affecting factors. The data were analyzed in order to indicate the differences in vol...

PURPOSE Test-retest reliability of the Functional Reach Test was examined in children with typical development by comparing standard and alternate methods. METHODS Eighty subjects ages seven to 16 years were tested and 69 retested for four methods of Functional Reach Test (ie, one-arm finger-to-finger, two-arm finger-to-finger, one-arm toe-to-finger, and two-arm toe-to-finger). Intraclass cor...

OBJECTIVE To quantify the relationship between the index to ring finger length ratio second digit:fourth digit(2D:4D) and radiographic osteoarthritis (OA) of the knee. METHODS Data from the Clearwater Osteoarthritis Study (COS) were analyzed. We selected a random sample of 236 subjects with knee OA (Kellgren-Lawrence scores >or=2) and compared their finger length ratio pattern with a random s...

Hand metastasis accounts for approximately 0.1 percent of all metastatic osseous malignancies. The lung, breast and kidney are the most common primary sources of these metastatic lesions.A rare case of retroperitoneal alveolar soft part sarcoma metastasizing to the distal phalanx of the second finger of the right hand is presented here. The patient underwent complete DIP amputation of the affec...
