STUDY DESIGN A within-subjects repeated measures design. OBJECTIVES To determine differences in the amount of vertical opening of the mandible among 3 different head positions. BACKGROUND Results from several studies have suggested that the position of the head and neck may affect temporomandibular joint function. Presently no standardized position of(More)
In this study we assessed the short-term effect of correcting leg length discrepancy on a vigorously performed task of resisted full body extension in 10 men, 18 to 35 years old, who had estimated leg length discrepancies of 10-15 mm. Using a cable ergometer we examined work performed, initial peak tension exerted on the ergometer, second peak tension, time(More)
A noninvasive kinematic recording technique involving geometric modeling of the knee joint was employed to determine anteroposterior displacements of the knee during walking. The model estimated how much the femoral condyles slid and rolled on the tibial plateau. Movement not due to sliding or rolling was attributed to horizontal translation of the tibia(More)
Orthotic prescription for forefoot posting is commonly based upon measures of the forefoot performed on a non-weightbearing foot. However, the relationship of measures of the unloaded foot to determine orthotic prescription for compensatory forefoot function during gait is still in question. Another approach to determine orthotic prescription is to measure(More)
Experimental evidence supports the general conclusion that 6 or more weeks of immobilization will cause joint contractures due to changes in the capsules of animals whose limbs have been traumatized. There is controversy whether contractures will form in 6 weeks in limbs which are free of trauma. The purpose of this study was to determine if range of motion(More)
The purpose of this study was to determine the ankle position at which the greatest peak torque occurs during isokinetic testing of inversion and eversion force. Testing of right foot invertors and evertors was performed at 10 degrees dorsiflexion, neutral dorsiflexion and plantarflexion, and 10 degrees plantarflexion on 25 untrained subjects with the MERAC(More)
This investigation was conducted to test the accuracy of unassisted pain maps drawn by patients with chronic pain. Three aspects of accuracy were investigated, the accuracy of the area of pain reported, whether all existing pains were reported, and whether related symptoms were reported. Thirty-six successive new admissions to a chronic pain rehabilitation(More)
Nine middle-aged women were examined to determine whether extension of the elbow in normal adults is limited primarily by muscle, or by ligaments and capsule. Terminal range of elbow extension was measured when the subject was normally relaxed and in the same subjects under conditions of paralysis induced by a myoneuro blocking agent. Relaxation of the(More)
