“…The average score of Dimeglio et al [11] for the three groups was 12.8 (range, [10][11][12][13][14][15] for the feet treated with the Ponseti method, 12.9 (range, 10-17) for those treated with the French method, and 14.1 (range, 10-17) for those feet that had undergone a surgery. There was no difference (p [ 0.05) in initial severity of deformity as rated by the score of Dimeglio et al [11] between the nonsurgical feet treated with the French PT method versus the Ponseti method, however feet that eventually required surgery were initially more severe (p = 0.0002) than those that did not.…”

We conducted gait analysis following initial nonoperative clubfoot treatment to compare lower extremity kinematic (eg, ankle motion) and kinetic (eg, ankle power) characteristics between patients treated as infants with Ponseti casting or French physical therapy. This is a followup report of gait characteristics at age 5 years in patients who had previously been tested at age 2 years. One hundred-twenty five clubfeet in 90 patients (34 feet only Ponseti treatment, 40 only French PT, and 51 feet initial nonoperative treatment followed by surgery) were included. The gait characteristics were compared to those of age-matched normal control subjects. Ankle equinus during gait occurred in 5% of feet treated with the French method and none of those treated by the Ponseti method. Increased stance phase ankle dorsiflexion persisted in 24% of feet treated by the Ponseti method. Intoeing was seen in 1 . 3 of both the French and Ponseti methods. Ankle push-off power was decreased compared to normal in patients treated by both methods, and even more so in operated feet. The presence or absence of Achilles tenotomy did not affect ankle power. Gait characteristics of feet that did not have surgery and maintained correction were superior to those of operated feet.

-Gait analysis may offer information to choose the best exercise-based clinical intervention for the children with clubfoot. However, other motor abilities are not commonly investigated. The aim of this research was to analyze the biomechanics of countermovement vertical jumping in clubfooted children who had undergone surgery. Fourteen children with idiopathic clubfoot were selected and the control group consisted of 11 children. Clubfooted children showed less dorsiflexion in the jump preparation phase. In the impulse phase, this group showed more knee flexion and less plantarflexion associated with less magnitude of vertical reaction force and less muscular activity in the gastrocnemius medialis. In the landing phase, for clubfoot group, we found high loading rate for the first peak of vertical force, less plantarflexion and more knee flexion. Understanding the biomechanical changes of vertical jump landing should assist in better targeting of physical and sporting activities of this population.

The muscle reacts physiologically in neuromuscular disorders which do not affect muscle tissue directly (such as muscular dystrophies), and adapts to altered demands. For this reason, alterations in the muscle-tendon apparatus are grossly secondary. Changing load stimulates an increase in muscle fibres, whereas continuous pull results in an increase in collagen fibres (fibrosis). The length range in which a muscle produces force must be considered with respect to the range of motion of the joint in order to plan soft tissue corrections and to understand the postoperative result. An optimal correction of muscle length can increase muscle force whereas overlengthening will reduce it. The latter is desired in cases where spastic muscle force needs to be reduced. In contrast shortening the muscle-tendon apparatus may be indicated in order to correct overlength and to increase muscle force. The effect of intramuscular lengthening procedures, performed as an aponeurotomy or an intramuscular tenotomy, depends on the stretching program after surgery. Extramuscular tendon lengthening, on the other hand, results in an immediate length gain. The danger of overlengthening and consecutive muscle weakening, however, is greater with the tendinous procedures.
