The XIX th Century: the gait century<br />

Du Bois Reymond (1818-1922) and Duchene (1806-1875) – Laid the foundations of electromyography<br />

Refined the methods for measuring currents in 1841, and traced electricity in<br />

contracting muscle to its independent fibres<br />

Volkmann (1862) – Described the effects of pressure on bone growth<br />

In 1866 published Physiologie des Movements,<br />

which describe the function of every important<br />

superficial muscle<br />

Van Mayer (1867) – Described the relationship between the bone architecture and its function<br />
