Nat Padhiar was a member of the Medical Service Team, the Clinical Lead and Team Leader for Podiatric Sports Medicine at The London 2012 Games and was based in the Polyclinic, Olympic Village in Stratford for the entire period of Olympic & Paralympic Games 2012. 
 
Nat holds membership in various surgical and SEM institutions. Nat is on the Editorial Board of the Sports Medicine section of Grand Rounds, the online medical journal, and the review panel for SEM and Foot Surgery journals. 
 
Clinical interests: (1) Foot Surgery, (2) Foot and ankle problems in Sport, (3) Exercise Induced Leg Pain in Sport, (4) Image-guided lower limb injections, (5) Sports Medicine and injury of the Lower Limb, (6) Dynamic intra-compartment pressure investigation for Chronic Exertional Compartment Syndrome; with a special interest in Exercise Induced Leg Pain and Achilles tendinopathy.
 
Nat Padhiar is a keen sportsman who continues to play cricket and tennis and participates in endurance sports (37 marathons, 2 Ultra-marathons and over 200 half marathons). He has represented Uganda School boys in cricket. In his professional capacity he has been part of the medical team and has attended World Student Games (1991), Commonwealth Games (2002), Island Games (2003), Everest Marathon (1993,1995), Mongolian Sunrise to Sunset Marathon (2001-2003), Daily Telegraph/British Brain & Spine Foundation London Marathon Team (1999-2007), London Triathlon (2005) and London 2012 Olympic & Paralympic Games (2012). 
 
He is not formally attached to professional football, rugby, or athletic clubs, but many clubs refer their sportsmen to him at his private clinics at London Independent Hospital.

Summary

A particular focus of my research has been exercise-induced leg pain (EILP) which is typically poorly managed, disabling and career ending for athletes if not optimally managed. Innovation has included novel diagnostic, measurement, and management approaches through award-winning contributions (e.g., BASEM Gold Medal) and papers in top-ranked journals (e.g., BJSM, BMJ, CJSM). In combination with my clinical work, my research has made me world-leading in this field.

The area of research is focused on Achilles Tendinopathy with innovating high volume image guided injection (HVIG) for the treatment of mid-portion Achilles tendinopathy (AT) which is now widely accepted as first line treatment of AT (JDR 2008, JSMS 2009, JMT 2010).

Teaching

Nat Padhiar is the module lead for (1) Sports Injuries and Podiatric Assessment, and (2) Advanced Clinical Practice.

His main pedagogic aim for the students is to further their vocational and liberal education (Sanderson, 1993) through professional socialisation, engaging in dialogue with a Socratic approach, to stimulate critical thinking. The aim is to achieve a qualification in SEM & PSM but more importantly, it is the knowledge and skills acquired that students could use with confidence in their clinical speciality.

He has expertise in Foot & Ankle problems in sport with a keen interest in Achilles tendinopathy, Exercise Induced Leg Pain in Sports with a keen interest in Chronic Exertional Compartment Syndrome of the foot and leg, and Image-guided injections.
