Plantar fasciitis (PF)is a degenerative syndrome of the plantar fascia resulting from repeated trauma at its origin on the calcaneus. Pain is generally caused by collagen degeneration at the origin of the plantar fascia at the medial tubercle of the calcaneus. It affects up to 10% of the general population. Functional risk factors include tightness in Gastrocnemius, soleus and weakness of intrinsic foot muscles because limited dorsiflexion of tight Achilles tendon strains the plantar fascia. Plantar fasciitis (PF), the most common cause of heel pain, it accounts for approximately 11% to 15% of foot symptoms presenting to physicians. The term plantar fasciitis implies an inflammatory condition. However, various lines of evidence indicate that this disorder is better classified as 'fasciosis' or 'fasciopathy' Plantar fasciitis. Main roles of plantar fascia are supporting longitudinal arch of the foot and providing shock absorption.if the tension on the plantar fascia exceeds the limits of the tissue, small tears can develop in the fascia. Repetitive tension and subsequent tearing can cause the fascia to become inflamed and painful. Plantar fasciitis is particularly common in runners, but is also noted among workers who stand for long periods.Any factor which is responsible for mechanical overloading of plantar fascia can be addressed as risk factors obesity, foot arch, decrease dorsiflexion ROM and tightness in calf muscles. One of the most common cause for limited ankle dorsiflexion range of motion (ADF)is gastrocnemius muscle tightness. The classic presentation of plantar fasciitis is pain on the sole of the foot at the inferior region of the heel. Pain is particularly bad with the first few steps taken on rising in the morning or after an extended refrain from weight-bearing activity. Often the pain diminishes after a few steps and through the course of the day, but returns if intense or prolonged weight bearing activity is carried out. Initially the heel pain may be diffuse or migratory; however, with time it usually focuses around the area of the medial tuberosity of calcaneum. Plantar heel pain is associated with impaired health-related quality of life including social isolation, a poor perception of health status and reduced functional capabilities.myofascial trigger points (MTrPs) in the calf muscle increase the stiffness and may reduce the dorsiflexion range of ankle joint which is one of the risk factor of plantar fasciitis.

Myofascial trigger points have the potential to create pain, limit ROM and restrict functional activities and should therefore be addressed as part of a comprehensive physical therapy program. Currently, a large variety of both manual and non-manual interventions exist for the deactivation of trigger points (TrPs). Manual approaches may include muscle energy techniques (METs), strain-counterstrain (SCS), myofascial release, proprioceptive neuromuscular facilitation, and ischemic compression.Integrated neuromuscular inhibition technique (INIT) is a method that includes three maneuvers in one. The three techniques are ischemic compression (IC) or trigger point release, strain counterstrain technique, and muscle energy technique (MET). In trigger point release, compression is given at the trigger point region and maintained for 15 seconds, while in strain counterstrain technique, the superficial fascia is stretched. MET works on the principle of reciprocal inhibition.Instrument-Assisted Soft Tissue Mobilization (IASTM) is uses specifically designed instruments to identify and treat myofascial restrictions. It is based off the principles of deep transverse friction massage. It is also known as Graston Technique. There are 6 stainless steel instruments which are specific for different regions and types of muscles which need to be targeted. It is designed to reduce fatigue of the clinician's hands and to detect lesions by amplifying the resonance felt through the instrument.
