Torque Development

The present study aimed to investigate the effect of isometric training on the elasticity of human tendon structures. Eight subjects completed 12 wk (4 days/wk) of isometric training that consisted of unilateral knee extension at 70% of maximal voluntary contraction (MVC) for 20 s per set (4 sets/day). Before and after training, the elongation of the tendon structures in the vastus lateralis muscle was directly measured using ultrasonography while the subjects performed ramp isometric knee extension up to MVC. The relationship between the estimated muscle force and tendon elongation ( L) was fitted to a linear regression, the slope of which was defined as stiffness of the tendon structures. The training increased significantly the volume (7.6±4.3%) and MVC torque (33.9±14.4%) of quadriceps femoris muscle. The L values at force production levels beyond 550 N were significantly shorter after training. The stiffness increased significantly from 67.5±21.3 to 106.2±33.4 N/mm. Furthermore, the training significantly increased the rate of torque development (35.8 ± 20.4%) and decreased electromechanical delay (−18.4±3.8%). Thus the present results indicate that isometric training increases the stiffness and Young's modulus of human tendon structures as well as muscle strength and size. This change in the tendon structures would be assumed to be an advantage for increasing the rate of torque development and shortening the electromechanical delay.

Ayurvedic Treatment

Myositis ossificansis characterized by heterotopic ossification (calcification) of muscle of various etiologies. It is most commonly affected in the quadriceps of the thighs. There are many tools available for diagnosis of Myositis ossificans, but lack of satisfactory treatment. So the development of a treatment protocol for Myositis ossificans is the need of today`s era. In Ayurveda, the same can be understood as Urusthamba. The present paper discusses a case of Myositis ossificans of right vastus lateralis muscle and its Ayurvedic treatment.

Palate Repair

A 6-year-old girl presented with a large recalcitrant oronasal fistula after bilateral cleft lip and palate repair and numerous secondary attempts at fistula closure. Incomplete palmar arches precluded a free radial forearm flap. A free vastus lateralis muscle flap was successfully transferred. No fistula recurrence was observed at 18 months. There was no perceived thigh weakness. The surgical scar healed inconspicuously. Free flaps should no longer be considered the last resort for treatment of recalcitrant fistulas after cleft palate repair. A free vastus lateralis muscle flap is an excellent alternative, and possibly a superior option, to other previously described free flaps.
