Leg length discrepancy (LLD) is an orthopaedic condition that involves a difference in length between the lower extremities. This is a significant medical problem, and the causes may be various trauma, diseases, deformities of the locomotor system, surgery, growth disorders, neurological illness, and others. Statistics have shown that up to 90 per cent of the population has LLD.

Croatian start-up Cognitus has developed a solution to measure leg length discrepancy and created insoles that can help correct posture and improve the quality of life.

Alan Mutka, one of the founders and chief technology officer at Cognitus Limited, as well as  a senior lecturer and research associate at the Rochester Insitute of Technology Croatia, spoke with Andrew Wrobel about his solution, as well as the challenges his start-up has faced.
