ABSTRACT We have compared the finger hyperextensometer (Jobbins et al., 1978) and the scoring system of Carter and Wilkinson (1964), modified by Beighton et al. (1973), in the quantification of joint laxity in a population selected to demonstrate a wide range of joint movement. Both systems correlated well (P less than 0.001) with a 'global index' of joint laxity derived by adding the arcs of movement recorded at most joints in the body by the method of the American Academy of Orthopaedic Surgeons (1965). The Carter and Wilkinson system produced better correlations and is the method of choice for assessing generalized joint laxity.

    ABSTRACT: Ergonomically, the flute is especially complex among wind instruments, and flautists may therefore be at particular risk of performance-related musculoskeletal disorders. Yet little is known about injury prevalence among flute players, and even less in those flautists who are also hypermobile. Recent research has found hand and wrist pain to be common complaints among flautists. Understanding of the predictors of injury and pain is therefore crucial as the presence of pain decreases performance quality and causes unnecessary time loss. There is a strong relationship between hypermobility and impaired proprioception, although many musicians may acquire greater proprioception than the average population. We have compared flexibility and proprioception of the hand in a study of flautists.

    ABSTRACT: General joint hypermobility is estimated to affect about 10% of the population and is a prerequisite of heritable connective tissue disorders where fragile connective tissue is a prominent feature. Pregnancy induced back pain is common whereas about 10% of women still have disabling pain several years after childbirth. The pathogenesis of the pain condition is uncertain, although several risk factors are suggested including general joint hypermobility. In the present study, the possible association of peripheral joint mobility in early pregnancy on the incidence of back pain with onset during pregnancy and persisting after childbirth was explored. A cohort of 200 pregnant women recruited from antenatal health care clinics was assessed by questionnaire and clinical examination, including measurement of passive abduction of the left fourth finger, throughout pregnancy and at 13 weeks postpartum. Comparisons were made between women with and without back pain. Statistical tests used were chi2-test, t-test, Spearman correlation and multiple logistic regression. In the cohort, the mean passive abduction angle of the left fourth finger increased from 40.1[degree sign] in early pregnancy to 41.8[degree sign] at the postpartum appointment. At the postpartum appointment, women in the back pain group had a significantly larger mean passive abduction angle of the left fourth finger of 4.4[degree sign], twice as many previous pregnancies and deliveries, and more than twice as frequent back pain in previous pregnancy, as compared with women with no persistent back pain. A similar pattern was displayed in late pregnancy. In a multiple regression analysis, the passive abduction angle of the left fourth finger in early pregnancy and the number of previous pregnancies were positively, significantly and independently associated to the incidence of back pain in late pregnancy and postpartum. Finger joint laxity as a reflection of constitutional weakness of connective tissue and number of previous pregnancies were associated with the development of back pain induced in pregnancy and persisting after childbirth. These factors may provide a foundation for development of targeted prevention strategies, but this have to be confirmed in future research including measurement of general joint laxity.

    ABSTRACT: Mandibular jaw opening was related with general joint mobility in a non-patient adolescent group. The angular rotation of the mandible at maximum jaw opening was slightly larger in females than in males and significantly larger in hypermobile individuals. No significant relationship between linear measuring of maximal mandibular opening capacity and peripheral joint mobility was found either at active (AROM) or at passive range of mandibular opening (PROM). PROM was strongly correlated to the mandibular length. Clinical signs in the great jaw closer muscles could not be associated to decreased AROM. The mean value of the difference between PROM-AROM (DPA) was 1.2 mm. Frequent clenching and/or grinding was correlated to increased DPA only in hypermobile adolescents (r = 0.49***). Those with DPA exceeding 5mm had all reciprocal clicking.
