Treatment of Sever’s disease by Podiatech


Sever’s disease is a form of osteochondrosis that occurs in the heel of some children.

It is a benign pathology typically found in physically active children. It causes progressive pain in the heel, which increases when exercising or walking.

The pain can be quite sharp and is felt primarily on palpation of the calcaneal tendon at the posteroinferior edge and on the lateral faces of the calcaneus, as well as during dorsiflexion of the ankle.

Children affected by the disease may limp and have a tendency to walk on tiptoes.

The effects of thermoformed plantar orthotics on the gait

 

This study was designed to determine the effects of wearing thermoformed orthotics incorporating lateral reinforcements on the spatial, temporal and kinematic parameters of the lower limbs whilst walking. The study comprised 14 healthy adults (10 men and 4 women). The effects of lateral reinforcements are thought to include limiting the pronosupination movements of the rear foot. These results may be due to the increase in tactile inputs caused by wearing thermoformed orthotics.

Evaluation of plantar orthotics for sport; in running

 
Plantar orthotics enable users to maintain the best possible balance in both static and dynamic situations. They have the potential to majorly influence pronation and supination of the rear foot whilst running or walking. Running is considered a fundamental precursor to a wide variety of sports - despite comprising a heterogeneous population; runners are generally inclined to consult a podiatrist.

Etude meta 1.jpg

Metatarsalgia

 

Metatarsalgia is the name given to a range of frequently occurring and potentially painful foot pathologies resulting from injury, vascular problems, osteoarthritic or bone patologies, neuralgia, bunions and ill-fitting footwear. Over the last 4 years these pathologies have accounted for 15% of patient consultations in referring sports orthopaedic centres. >> see article

Etude Thomas stieff.jpg

Influence of CUSTOM-MOULDED Footorthoses (NFO) with neuromuscular operating elements on muscle activity during treadmill walking

 

NFO has controversially been discussed but not evaluated. In contrast with recent studies we are interested in muscular activation. On the basics of the effects detected, a better understanding and treatment for NFO should result in increased patient benefits.

The effects of thermoformed plantar orthotics incorporating lateral reinforcements on gait parameters

 

Orthotics ensure that the static and dynamic functionality of feet are as close as possible to the ideal. They have a major influence on rear foot pronation and supination during running or walking and in addition insertion of these orthotics alters plantar pressure and the proprioceptive and tactile inputs of the foot.

The objective of this study was to determine the effect of wearing thermoformed orthotics with lateral reinforcements on the spatial, temporal and kinematic parameters of the lower limbs during walking. >> see article
