Plantar fasciitis is a common foot complication. It is a disorder of the connective tissue which supports the arch of the foot. It causes pain in the heel and bottom of the foot that is usually most severe with the first steps of the day or following a period of rest. The present study deals with purposively selected 50 patients with plantar fasciitis aged 25-45 years from Physiotherapy Center of Guru Nanak Dev University, Amritsar, Punjab, India. The subjects were randomly allocated into two groups, calf stretching and Achilles tendon stretching for 4 weeks interventions. To evaluate the pain and foot function disability of the patients, visual analogue scale (VAS) and foot function index (FFI) were assessed from all the subjects in pre- and post-intervention stages. The results indicated significant reduction (p<0.001) in VAS and FFI in patients with Plantar fasciitis after 4-week interventions using both calf stretching and Achilles tendon stretching. The patients treated with Achilles tendon stretching had more significant (p<0.001) reduction both in VSA and FFI than the patients treated with calf stretching. In conclusion it could be stated that Patients who reported significant relief from symptoms at the end of 4-week interventions with Achilles tendon stretching were double that of the calf stretching.
