Sensibilidade dolorosa à palpação em pacientes con disfunção temporomandibularr crônica

The cephalalgias are frequently associated with the temporomandibular disorders being common to find an increase of pain sensitivity in these patients. Thus, the objective of present study was to assess the sensitivity to palpation in patients presenting with chronic temporomandibular disorders comparing two groups one with headache and other without it, respectively. The temporomandibular disorders and the primary cephalalgias were diagnosed according the Diagnostic Criteria for the Research of Temporomandibular Disorders and by a questionnaire based on the International Classification of the Cephalalgias (2004). Location, assessment and grouping of muscular and articular areas for palpation were carried out according to the Diagnostic Criteria for above mentioned disorders, considering bilaterally the masseter muscle, the temporalis muscle, the cervical region and the temporomandibular joint. Sample included 213 (88.0 %) of women and 29 (12.0 %) men with a mean age of 37.41 years. The mean of number of zones positive to palpation in the groups without headaches, tension headache, migraine and daily chronic headache were: 12.43, 14.38, 15.21 and 15.62 (p= 0.107) (min 2 max 22). The areas of temporalis muscle showed significant differences among groups (p= 0.007). The number of painful points was not statistically different among groups and only in the temporalis muscle there were differences with statistical significant to palpation.

Fatigue and rapid hamstring/quadriceps force capacity in professional soccer players

The aim of this study was to investigate the effect of fatigue induced by an exhaustive laboratory-based soccer-specific exercise on different hamstrings/quadriceps (H:Q) ratios of soccer players. Twenty-two male professional soccer players (23·1 ± 3·4 year) performed maximal eccentric (ecc) and concentric (con) contractions for knee extensors (KE) and flexors (KF) at 60° s-1 and 180° s-1 to assess conventional (Hcon:Qcon) and functional (Hecc:Qcon) ratios. Additionally, they performed maximal voluntary isometric contraction for KE and KF, from which the maximal muscle strength, rate of force development (RFD) and RFD H:Q strength ratio (RFDH:Q) were extracted. Thereafter, subjects were performed an exhaustive laboratory-based soccer-specific exercise and a posttest similar to the pretest. There was significant reduction in Hcon:Qcon (0·60 ± 0·06 versus 0·58 ± 0·06, P<0·05) and in Hecc:Qcon (1·29 ± 0·2 versus 1·16 ± 0·2, P<0·01) after the soccer-specific exercise. However, no significant difference between Pre and Post exercise conditions was found for RFDH:Q at 0-50 (0·53 ± 0·23 versus 0·57 ± 0·24, P>0·05) and 0-100 ms (0·53 ± 0·17 versus 0·55 ± 0·17, P>0·05). In conclusion, H:Q strength ratios based on peak force values are more affected by fatigue than RFDH:Q obtained during early contraction phase. Thus, fatigue induced by soccer-specific intermittent protocol seems not reduce the potential for knee joint stabilization during the initial phase of voluntary muscle contraction. copy; 2012 Scandinavian Society of Clinical Physiology and Nuclear Medicine.
