The Effect of Integrated Neuromuscular Inhibition Technique on Functional Performance and Balance in Subjects with Plantar Fasciitis

The plantar fascia is considered a degenerative condition which develops due to repeated biomechanical stress and microtrauma over the fascia. Those suffering from plantar fasciitis experience an insidious onset of sharp pain over the inferomedial aspect of the heel which radiates into the arch of the foot. This pain is most intensified during the first step in the morning after the foot has been in a status of non-weight bearing for a long duration. Studies have also indicated that muscle trigger points within gastrocnemius muscle, abductor digiti minimi and flexor digitorum brevis can lead to the development of heel pain. Patients with plantar fasciitis employ compensatory mechanisms to reduce the discomfort from the plantar fascia. These strategies alter the joint position sense and muscle activation which make it difficult to maintain an upright posture within the base of support which can impair both static and dynamic balance.

There are several approaches in trigger point release which has been demonstrated; the combined comprehensive approach referred to as Integrated Neuromuscular Inhibition Technique (INIT) includes ischemic compression (IC), strain counter-strain (SCS) and muscle energy techniques (MET).

The ongoing evolution in research of conservative treatment methods of plantar fasciitis highlights the need to explore methods that offer long-term effectiveness. The study aims to address the gap in literature, examining the combined effect of INIT on plantar fasciitis and contributing valuable insights to the field.
