Emotional stimuli receive prioritized attentional and motoric processing in the brain. Recent data have indicated that emotional stimuli enhance activity in the cervical spinal cord as well. In the present study, we used fMRI to investigate the specificity of this emotion-dependent spinal cord activity. We examined whether the limb depicted in a passively viewed image (upper vs. lower) differen...

Ambulatory accelerometry is a technique that allows objective measurement of aspects of everyday human behavior. The aim of our research has been to develop, validate, and apply this technique, which recently resulted in an upper limb activity monitor (ULAM). The ULAM consists of body-mounted acceleration sensors connected to a waist-worn data recorder and allows valid and objective assessment ...

INTRODUCTION Angio-osteohypotrophic syndrome is also known as Servelle-Martorell angiodysplasia. It is characterized by venous or, rarely, arterial malformations, which may result in limb hypertrophy and bony hypoplasia. Extensive involvement of the upper limb is a rare feature of Servelle-Martorell syndrome. Cases with minimal upper limb involvement have been described in the literature. CAS...

The authors investigated whether force control is similar between the upper and lower limbs and between contractions that involve 1 or 2 joints. Six volunteers (27.5 +/- 11.2 years of age) attempted to produce consistent discrete rapid force responses of 30, 60, and 90 N by using 6 different body postures, 3 with the upper and 3 with the lower limb. One of the postures for each limb involved 2 ...

INTRODUCTION Functional impairment of [parts of] the upper limb has many different expressions. Sound biomechanical analysis is at the basis of the management of the physical challenges involved. An outline of the basics of a mechanical systems approach is presented below. Orthoses are among the many treatment options for upper limb impairments. An orthosis can be defined as a mechanical constr...

OBJECTIVES A systematic review and meta-analysis using the Grades of Recommendation, Assessment, Development and Evaluation (GRADE) approach; evaluating Botulinum Toxin type A efficacy on improving ease of care in the upper/lower limb. DATA SOURCES Pubmed, Cinahl, Amed, Embase and Cochrane databases. English Language. Search to July 2014. REVIEW METHODS All randomized, placebo controlled tr...

OBJECTIVE To assess and compare the oral hygiene and periodontal status among children with Poliomyelitis having upper limb disability, lower limb disability and both upper and lower disability at Udaipur city, Rajasthan, India. STUDY DESIGN Total sample comprised of 344 Poliomyelitis children (upper limb disability: 33.4%; lower limb disability: 33.7%; both upper and lower limb disability: 3...

OBJECTIVES Patients without voluntary finger extension early post-stroke are suggested to have a poor prognosis for regaining upper limb capacity at 6 months. Despite this poor prognosis, a number of patients do regain upper limb capacity. We aimed to determine the time window for return of voluntary finger extension during motor recovery and identify clinical characteristics of patients who, d...

Abstract An upper limb motion assist robot to elderly and disabled people is proposed in this paper. The robot can be mounted on a wheelchair to actuate an elderly person’s upper limb three dimensionally by his will. A wrist of an arm is suspended, and actuated by a wire driven control system. A vibration reduction system is also developed to decrease the vibration occurred in the wire driven s...

Only few artificial limbs for total upper arm replacement includes other active joints than those of hand and elbow. The main cause is the difficulty to the set up the limb command system. Some components of artificial upper arm have been recently designed and built by the our research group. The full arm consists of a two active axes shoulder and a single axis elbow, plus a commercial hand. Th...
