Gait analysis / Biomechanics

Podiatry Biomechanics London

At the London Podiatry Clinic we use the Video Gait Analysis Diagnostic Management System (VGADMS) to achieve the most accurate diagnosis of the way you move your whole body. This is done by walking, running but also by skipping, hopping, lunging or cycling. The gait analysis assessment enables to highlight biomechanical abnormalities.


Overpronation of the foot is not an injury itself but if you over pronate, then you may be more susceptible to a number of sports injuries. Excess pronation usually causes overuse type injuries, occurring most frequently in runners but it can occur either in fencers or any sport’s athlete. When a neutral foot pronates during walking or running, the lower leg, knee and thigh all rotate internally (medially). When an athlete over pronates, this inwards rotating movement is exaggerated. In turn, this increases the stresses on the muscles, tendons and ligaments of the foot, lower leg including shin and knee as the limb rotates in too far.

Common injuries with overpronation:

  • Shin splints
  • Anterior compartment syndrome
  • Patello-femoral pain syndrome
  • Plantar fasciitis
  • Tarsal tunnel syndrome
  • Bunions (Hallux valgus)
  • Achilles tendonitis


Oversupination also called hyper-supination is far more rare than overpronation and causes problems for runners and other athletes, as in this position the foot is less able to provide shock absorption. It therefore predisposes the athlete to:

  • Shin splints
  • Plantar fasciitis
  • Ankle sprains
  • Stress fractures of the tibia, calcaneus and metatarsals

Increased Q angle

The Q angle of the knee is a measurement of the angle between the quadriceps muscles and the patella tendon and provides useful information about the alignment of the knee joint.

  • Hip hiking (or hitching) – lifting the hip on one side
  • Ankle equinus – limited ankle dorsiflexion
  • Pelvic tilt – can be either anterior, posterior or lateral

These biomechanical problems are usually caused by muscular imbalances (tight muscles working against weak muscles), although they can sometimes be caused by structural problems, such as leg length discrepancies resulting in hip hiking.

We establish a comprehensive assessment of the structure, alignment and function of the whole body when standing and during walking.

A biomechanical assessment will help to determine if you will benefit from orthotic therapy, stretching or strengthening exercises, footwear changes, strapping, splinting, massage or other therapies. This individualised approach to assessment and treatment provides effective, targeted and prompt recovery from injury and relief of painful symptoms.
