Commercial multi-degrees-of-freedom (multi-DOF) myoelectric hand prostheses can perform various gestures and grip motions using multiple DOFs. However, as most upper limb amputees have less than two electromyogram (EMG) signals generated at the amputation site, it is difficult to control multi-DOF prostheses. This paper proposes a multifunctional prosthesis system that uses only EMG sensors whi...

Single pulse transcranial magnetic stimulation (TMS) was used to test the assumption that kinesthetic imagery of action is more 'motor' than visual imagery of action. We assessed corticospinal excitability during motor imagery of a thumb-palm opposition movement by recording potentials evoked by TMS from two hand muscles that would (opponens pollicis, OP, target) or would not (abductor digiti m...

  Abstract   Background: Traumatic or congenital events can result in injury and functional   deficiency in the hand and we need to reconstruct the fingers at times. Studies are   available in the pediatric and adult age groups to assess the length of the thumb. But   to the best our knowledge no measurement of the relative clinical length of all fingers   has been reported in the literature. W...

When holding a tablet computer with two hands, the touch keyboard configuration imposes postural constraints on the user because of the need to simultaneously hold the device and type with the thumbs. Designers have provided users with several possible keyboard configurations (device orientation, keyboard layout and location). However, potential differences in performance, usability and posture...

This article was accepted fur publication September 26, 1991. Behavioral research has indicated that thumbsucking often covaries with hair pulling and that the elimination of thumb-sucking can result in the elimination of the hair pulling with which it was associated (e.g., Frlman & Hove, 1987; Knell & Moore, 1988). Treatments for persistent thumb-sucking, however, have shown minimal or transie...

This case report demonstrates the treatment effects of palatal crib combined with the myofunctional therapy in a child with anterior open bite (AOB) due to thumb sucking and habitual anterior and low tongue position. The patient, an 11-year-old boy, had an anterior open bite and flared and spaced upper and lower incisors. Palatal cribs in conjunction with myofunctional therapy were used to disc...
