Evaluation of mandibular condylar movement exercise for patients with internal derangement of the temporomandibular joint on initial presentation.
Summary of "Evaluation of mandibular condylar movement exercise for patients with internal derangement of the temporomandibular joint on initial presentation."
The aim of the present study was to evaluate mandibular condylar movement in a group of Japanese women who presented with closed lock of the temporomandibular joint. A total of 148 women aged between 19 and 75 years were included in the study. We examined mouth-opening, protrusion, and lateral excursive movements, and divided the patients into two groups (74 experimental cases and 74 controls). The experimental group was treated with exercises of the mandibular condyle, and the median (range) maximum mouth-opening increased from 27 (range 11-34)mm to 38 (24-47)mm. In control cases, it increased from 29 (range 20-35)mm to 30 (20-39)mm without exercise. In the experimental group, the median (range) maximum lateral movement on the opposite (unaffected) side increased from 8 (3-12)mm to 9 (5-13)mm. In the control group it remained similar at 7 (3-12)mm and 7 (3-12)mm. In the experimental group, the median (range) lateral movement on the affected side increased from 6 (2-13)mm to 8 (3-13)mm. In controls it remained similar at 6 (2-12)mm and 6 (2-12)mm. In the experimental group, the median (range) maximum protrusion increased from 6 (3-12)mm to 7 (4-12)mm, and in the control group from 6 (2-10)mm to 7 (2-10)mm. There was a significant difference between the experimental (50/74, 68%) and control groups (3/74, 4%) in the degree of increased mouth-opening. Exercise of the first mandibular condylar seems to be useful in the treatment of closed lock on initial treatment.

Medical and Biotech [MESH] Definitions
Mandibular Condyle
The posterior process on the ramus of the mandible composed of two parts: a superior part, the articular portion, and an inferior part, the condylar neck.
Echocardiography, Stress
A method of recording heart motion and internal structures by combining ultrasonic imaging with exercise testing (EXERCISE TEST) or pharmacologic stress.
Exercise Tolerance
The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an EXERCISE TEST.
Cytoplasmic Streaming
The movement of CYTOPLASM within a CELL. It serves as an internal transport system for moving essential substances throughout the cell, and in single-celled organisms, such as the AMOEBA, it is responsible for the movement (CELL MOVEMENT) of the entire cell.
Exercise Test
Controlled physical activity, more strenuous than at rest, which is performed in order to allow assessment of physiological functions, particularly cardiovascular and pulmonary, but also aerobic capacity. Maximal (most intense) exercise is usually required but submaximal exercise is also used. The intensity of exercise is often graded, using criteria such as rate of work done, oxygen consumption, and heart rate.
