Inclusion criteria
Inclusion criteria: 1. Participants admitted to the study will range between the ages of 50 and 75. 2. Participants must have a formal diagnosis of intermittent claudication of at least 3 months confirmed by a consultant vascular surgeon. This diagnosis will be derived using colour-flow duplex scan, medical history and examination, and absence or reduction in foot pulses, an ankle brachial pressure index (ABPI) of less than 0.8. 3. Participants must be able to walk a minimum of 100 m or perform 2 minutes of continuous walking unaided. 4. Healthy participants must be aged 50 or over.
Exclusion criteria
Exclusion criteria: 1. Active or a prior history of foot ulcers 2. Significant foot deformities necessitating use of foot orthoses 3. Self-reported complete neuropathy in their feet (a reported lack of diabetes will be verified through a foot sensation test) 4. Surgery in the previous 6 months 5. Pain in their lower limbs or back with a cause unrelated to PAD/IC 6. Painful knee, ankle or hip osteoarthritis 7. Total reliance on walking aids 8. Prior lower limb joint replacement 9. Morbidly obese (BMI>35). Marker placement relies on identification of joint centres and bony landmarks and these must be easily palpated by hand. 10. Healthy participants must not have any of the following: significant pain in the legs when walking, prior injury to the legs or spine, diabetes, foot deformities, prior joint replacement or major orthopaedic surgery.
