Joint hypermobility is a clinical entity that has been little studied in Southeast Asia in contrast to the many studies that have been conducted in the West. A pioneer study was conducted in Singapore involving 306 subjects from the three major races i.e. Chinese, Malays and Indians. Their ages ranged from 15 to 39 years. The objective was to ascertain the joint mobility profile in a study samp...

Even when the muscles surrounding a joint are inactive, they still exert a damping effect on joint mobility, because of the passive elastic tension exerted by the stretched muscle fibres and their connective tissue (Clemmesen, 1951). For example, if the forearm muscles are allowed to relax and the forearm is then shaken violently, the hand will swing loosely at the wrist; however, if the experi...

Markov distributions describe multivariate data with conditional independence structures. Dawid and Lauritzen (1993) extended this idea to hyper Markov laws for prior distributions. A hyper Markov law is a distribution over Markov distributions whose marginals satisfy the same conditional independence constraints. These laws have been used for Gaussian mixtures (Escobar, 1994; Escobar and West,...

BACKGROUND Joint pain is extremely common in older people, but its natural history has been little described in the UK literature. METHODS A UK general practice population was followed for 1 yr in 1998. There were 4804 subjects aged 75 yr and over who accepted the offer of health screening. Assessments by postal questionnaire using the Elderly At Risk Rating Scale, which includes one question...

The DNA structure of a fragment containing the SV40 termination sequences was examined using gel mobility assays. The region is shown to contain a DNA bend as evidenced by an abnormal mobility that is progressively accentuated as the temperature is lowered. This represents the strongest example of DNA bending among the collection of SV40 fragments studied. The same fragment was shown previously...

The aim of this paper is the study of some laws of random probability distributions, called hyper Dirichlet processes, charging the product of three sample spaces, with the property that the first and the third components are independent conditional to the second one. The law of the marginals on the first two and on the last two components are specified to be Dirichlet processes with the same m...

Foot pain is highly prevalent in older people and has a significant detrimental impact on mobility and quality of life. In recent years, there has been increased interest in exploring the biomechanical factors that may contribute to the development of foot disorders and the associated impairment of mobility in this age group. Studies have shown that with advancing age, there is a general tenden...

Three hundred and fifty seven subjects (178 males and 179 females) with insulin dependent diabetes mellitus were evaluated for the presence of limited joint mobility of the interphalangeal joints. Sixty six subjects (19%) had stage 1 and 26 subjects (7%) had stage 2 involvement of their interphalangeal joints. The presence of contractures was significantly related to mean longitudinal glycated ...

Recent studies have presented range of motion (ROM) data in degrees for dinosaur forelimb joints, usually via physical manipulation of one individual. Using these data, researchers have inferred limb orientations, postures, gaits, ecological functions and even phylogenetic trends within clades. However, important areas of concern remain unaddressed; for example, how does ROM at a forelimb joint...
