Remote monitoring of Parkinson's Disease (PD) patients with inertia sensors is a relevant method for a better assessment of symptoms. We present a new approach for symptom quantification based on motion data: the automatic Unified Parkinson Disease Rating Scale (UPDRS) classification in combination with an animated 3D avatar giving the neurologist the impression of having the patient live in fr...

BACKGROUND AND PURPOSE There is no consensus on the difference in effects of internal fixation (IF) and external fixation (EF) on outcomes for the treatment of distal radius fractures. We performed a meta-analysis of randomized clinical studies. METHODS We searched the literature and included studies that compared the effects of IF and EF on the treatment of distal radius fractures. Statistic...

BACKGROUND Terrible triad (TT) is one of the severe injuries of the elbow that generally requires surgery. Nonsurgical treatment has recently been applied in selected cases of TT injury. Evaluation of the results of this treatment was the main aim of this study. METHODS In a prospective cohort study, 10 patients with a mean follow-up of 30.6 months were evaluated. The inclusion criteria inclu...

This paper describes the development and evaluation of a musculoskeletal model that represents human elbow flexion-extension and forearm pronation-supination. The length, velocity, and moment arm for each of the eight musculotendon actuators were based on skeletal anatomy and joint position. Musculotendon parameters were determined for each actuator and verified by comparing analytical moment-a...

From 1990 to 1994 we undertook arthroscopy of the ankle on 34 consecutive patients with residual complaints following fracture. Two groups were compared prospectively. Group I comprised 18 patients with complaints which could be attributed clinically to anterior bony or soft-tissue impingement. In group II the complaints of the 16 patients were more diffuse and despite extensive investigation t...

The aim of this review was to examine the literature on the effects of surgery of the spastic hand in children with cerebral palsy on functional outcome and muscle coordination. We performed a search of the relevant literature in Medline, Embase, and Biological Abstracts from 1966 to June 2006. The search resulted in eight studies on the effect of surgery on functional outcome and three studies...

We present a practical system for controlling the prehension of a transradial prosthesis. The system is mounted on the artificial hand and comprises simple hardware and software that are convenient for real-time implementation. The hardware consists of a standard web camera and an ultrasound distance sensor. The control algorithm mimics biological mechanisms for the control of grasping and uses...

The effect of involvement of the distal radio-ulnar joint on subsequent function was studied in 170 patients with Colles' fractures, reviewed for one year after cast removal. Patients with involvement of this joint had significantly weaker grips and a significantly greater incidence of pain and tenderness over the joint at all stages of follow-up. They also had a poorer range of supination at s...

Background For decades, tuberculosis (TB) has posed a great threat to people worldwide. Bone and joint TB is one of the most common types of extrapulmonary TB, with elbow TB comprising a small proportion of these cases. The treatment for elbow stiffness associated with TB has been rarely reported. Patients and methods We retrospectively analyzed six patients (four females and two males) with ...

BACKGROUND An estimated 30-50% of essential tremor (ET) diagnoses are incorrect, and the true diagnosis in those patients is often Parkinson's disease (PD) or other tremor disorders. There are general statements about the tremor in these ET and PD, but published data on the more subtle characteristics of tremor are surprisingly limited. Postural tremor may occur in both disorders, adding to the...
