Tissue expansion is an invaluable reconstructive strategy after surgical excision of a congenital naevus. However, reducing the number of operations is very important for patients with a giant congenital naevus. We used a large pedicle expanded flank flap to successfully treat a giant circumferential naevus that extended from the left upper arm to the wrist, which also provided excellent contour and colour match. We consider this an effective and convenient method to treat a circumferential naevus covering almost the entire upper limb of the paediatric patient.

The thumb-in-palm (TIP) pattern is one of the most common upper limb deformities in cerebral palsy (CP). This study was designed to investigate the effect of the dynamic TIP pattern on upper limb function in children with spastic CP. This prospective observational study included a total of 106 children with CP with dynamic TIP. The House TIP classification while grasping small or large objects, Melbourne Assessment of Unilateral Upper Limb Function (MUUL), Shriners Hospital Upper Extremity Evaluation (SHUEE), Zancolli classification for wrist–finger flexor deformity, and degree of swan neck deformity were assessed. Type I was the most common and highest functioning House TIP classification type. However, there were no significant differences in upper arm function between types II, III, and IV. The three components of the SHUEE showed stronger association with MUUL than House TIP and Zancolli classifications. After multivariable analysis, functional use of the wrist–finger and the thumb played a more significant role than the dynamic alignment of the thumb. In conclusion, the House TIP classification is useful to describe the TIP pattern. The SHUEE thumb assessment is a useful tool for reflecting upper arm function. The upper arm function was related more with the associated wrist flexor deformity than dynamic TIP.

The design of an upper limb rehabilitation robot for post-stroke patients is considered a benchmark problem regarding improving functionality and ensuring better human–robot interaction (HRI). Existing upper limb robots perform either joint-based exercises (exoskeleton-type functionality) or end-point exercises (end-effector-type functionality). Patients may need both kinds of exercises, depending on the type, level, and degree of impairments. This work focused on designing and developing a seven-degrees-of-freedom (DoFs) upper-limb rehabilitation exoskeleton called ‘u-Rob’ that functions as both exoskeleton and end-effector types device. Furthermore, HRI can be improved by monitoring the interaction forces between the robot and the wearer. Existing upper limb robots lack the ability to monitor interaction forces during passive rehabilitation exercises; measuring upper arm forces is also absent in the existing devices. This research work aimed to develop an innovative sensorized upper arm cuff to measure the wearer’s interaction forces in the upper arm. A PID control technique was implemented for both joint-based and end-point exercises. The experimental results validated both types of functionality of the developed robot.

The purposes of this study were to examine the consistency of wheelchair athletes’ upper-limb kinematics in consecutive propulsive cycles and to investigate the relationship between the maximum angular velocities of the upper arm and forearm and the consistency of the upper-limb kinematical pattern. Eleven elite international wheelchair racers propelled their own chairs on a roller while performing maximum speeds during wheelchair propulsion. A Qualisys motion analysis system was used to film the wheelchair propulsive cycles. Six reflective markers placed on the right shoulder, elbow, wrist joints, metacarpal, wheel axis, and wheel were automatically digitized. The deviations in cycle time, upper-arm and forearm angles, and angular velocities among these propulsive cycles were analyzed. The results demonstrated that in the consecutive cycles of wheelchair propulsion the increased maximum angular velocity may lead to increased variability in the upper-limb angular kinematics. It is speculated that this increased variability may be important for the distribution of load on different upper-extremity muscles to avoid the fatigue during wheelchair racing.

This research addresses attention to human upper limb experimental analysis during feeding process aiding disabled persons. The research core is focused on the experimental process of obtaining the angular amplitudes and trajectories developed by the human upper arm during feeding process. The research originality consists on the obtained results which can be used in further researches for command and control of robotic assisting devices.

Abstract Background  Parkes Weber syndrome (PWS) is a congenital disease characterized by vascular malformations, such as arteriovenous fistulas (AVFs). It frequently presents with overgrowth of a lower limb and high-output heart failure. The main treatment is to close vascular malformations. Surgical excision or endovascular coil insertion was performed in a few patients with AVFs. However, vascular covered stent implantation has not been used for treating PWS. Case summary  A 15-year-old male patient with PWS presented to our hospital because of dyspnoea and massive left upper limb swelling. After initial examination and left upper limb angiography, his symptoms and findings were attributed to the presence of high-flow large AVFs despite the presence of many coils previously inserted. We decided to implant a covered stent along the AVFs between the subclavian and axillary arteries. After stent implantation, the patient’s complaints and findings improved during the early term but they relapsed at the 6th month after percutaneous intervention. Discussion  Here, we report for the first time the use of covered stent implantation and its short and 6 months results in a patient with PWS. Although initial improvements were noted, the clinical outcome at 6 months after stent implantation was poor. This was probably associated with the presence of widespread subtle AVFs or collateral connections among the existing AVFs. Based on our result, we propose that closure of large AVFs is not useful and more definitive interventions, such as limb amputation may be required earlier.

In the high-velocity tennis serve, the contributions that the upper limb segments' anatomical rotations make to racket head speed at impact depend on both their angular velocity and the instantaneous position of the racket with respect to the segments' axes of rotation. Eleven high-performance tennis players were filmed at a nominal rate of 200 Hz by three Photosonics cameras while hitting a high-velocity serve. The three-dimensional (3-D) displacement histories of 11 selected landmarks were then calculated using the direct linear transformation approach, and 3-D individual segment rotations for the upper limb were calculated using vector equations (Sprigings, Marshall, Elliott, & Jennings, 1994). The major contributors to the mean linear velocity of the center of the racket head of 31.0 m · s-1 at impact were internal rotation of the upper arm (54.2%), flexion of the hand (31.0%), horizontal flexion and abduction of the upper arm (12.9%), and racket shoulder linear velocity (9.7%). Forearm extension at the elbow joint played a negative role (-14.4%) and reduced the forward velocity of the center of the racket at impact.

AbstractBronchogenic cysts are rare congenital benign lesions that are usually detected in the paediatric patient with symptoms of infection or compression on vital structures. They are rarely diagnosed in the adult population. We present a case of bronchogenic cyst presenting as a lump in the neck in an adult patient. Radiological imaging helped to diagnose this lesion accurately before any form of intervention. Complete surgical excision is the treatment of choice.
