The purpose of the study was to describe and analyze the dance movements of the Philippine folk dance Itik-itik. The researchers adopted the movement analysis method similar to that of Mackenzie that involves the (1) description of the actual movements which occur at the joints involved; (2) the plane in which the movement occurs; and (3) the muscles producing the movement (agonist & antagonist). In addition, similar to the study of Martin and Miller, the researchers also had done a mechanical analysis on the lever type involved in the execution of the dance movement in terms of force, axis, and resistance. Results revealed that the prominent dance steps in the Philippine local dance Itik-itik are the (1) running, (2) cross step, slide close, slide close step, (3) heel, close-ball, close arm, (4) step, slide-close, slide, (5) arms extension/flexion, and (6) flapping of the arms. The joints involved are the shoulder and hip muscle which are ball and socket type of joints; and elbow, knee and ankle which are hinge joints. The major muscles involved in the dance for the lower body include the quadriceps, hamstring muscle group, adductor muscle group, calves and gluts. While for the upper body muscles involved are the pectoralis major, latissimus dorsi, deltoid, trapezius, biceps, and triceps muscles. The type of lever used in performing the dance comprise majority of 1st class and 3rd class levers. By knowing the muscles involved in the dance the dance teacher may be able to devise activities to gradually prepare the prime mover muscles before the actual execution for injury prevention. Thus, the movements in the dance may improve the health and skill related fitness of the performers.

Objective: The objective of this study was to determine the elasticity of sternocleidomastoid muscle (SCM) in patients with congenital muscular torticollis (CMT). Methods: In all, 41 patients and 22 controls were included in the study, and the elasticity of the patients’ SCM was measured. Echogenicity, thickness, and strain values of the SCM were also obtained. Results: The thickness and strain values of the SCM were higher in the patient group than in the control group ( P = .02 and P = .15). For median values, there was no difference in echogenicity and strain. In the strain elastography evaluation of the receiver operating curve (ROC) for muscle echogenicity in the isoechoic muscle group, the specificity and sensitivity were determined to be 100% and 22%, respectively, for the area under the curve (AOC) value of 0.558 (95% confidence interval [CI], 0.424–0.6686), and the cutoff value was <1.4. In the hyperechoic muscle group, the ROC for AUC values was found to be 0.542 (95% CI, 0.411–0.6686), and the cutoff value was >1.4 with 100% sensitivity and 20.75 specificity. Conclusions: The strain elastography technique can be used in the diagnosis of CMT.
