Study Procedure: Subjects will be selected according to the inclusion and exclusion criteria. The subjects will be divided into two groups: Group A and Group B. The ankle goniometry, VAS, FFI and FAAM scores will be recorded at baseline and after the last treatment. Treatment will consist of a 3-week program. For the initial 2 weeks, session will be administered 5 days a week. In a final week, treatment will be provided in 2 sessions.

Intervention:

Group A
Participants in Group A will receive Muscle Energy Technique (MET) and Ultrasound Therapy, followed by a exercise program.

·       Muscle Energy Technique (MET):

For gastrocnemius muscle, the subject will lie in a supine position with the knee fully extended, and the therapist will stand on the affected side. The therapist will dorsiflex the subject’s ankle joint until resistance is felt. The subject will be asked to hold this position and exert 20% of their force towards plantar flexion for 5-7 seconds. Then, the resistance will be released, and the subject will relax for 5 seconds. The therapist will passively dorsiflex the ankle joint to a new barrier. A set of 5 repetitions will be given.

For soleus muscle, the subject will be in a supine position, keeping the knee slightly flexed, and the therapist will stand on the affected side in a walking position. The subject’s ankle joint will be dorsiflexed until resistance is felt, and they will be asked to hold this position and exert 20% of their force towards plantar flexion for a period of 5 to 7 seconds. Then, the resistance will be released, and relaxation for a period of 5 seconds will be given, during which the ankle will be passively dorsiflexed to a new barrier. A set of 5 repetitions will be performed.

·        Ultrasound Therapy: US therapy will be applied using the following parameters: continuous mode, base frequency of 1 MHz to produce a deeper penetration, power of 2 W/cm2 into the areas of the painful heel, insertion of the plantar fascia on the medial calcaneal area, and the myofascial junction at the dorsum of the heel for 5 minutes using an ultrasound gel.

·        Exercises: 1. Stretching of the hamstrings and ankle plantar flexors (straight leg raise in the supine position).

2.Stretching of Calf muscles: The patient leaned forward in the standing position with the affected foot farther away from the wall, while keeping the heel on the floor; the soleus muscle was emphasized with the knee flexed and the gastrocnemius muscle with the knee extended.

3.Stretching of the plantar fascia: in the sitting position, the patient crossed the affected foot over the contralateral thigh and performed passive extension of the metatarsophalangeal joints.

Group B
Participants in Group B will receive Positional Release Technique (PRT) and Ultrasound Therapy. followed by a exercise program.

• Positional Release Technique (PRT): Group PRT will receive positional release technique. The subjects will be made to lie in a supine position with the affected limb out of the plinth, and then slight mechanical pressure will be put on the tender point with one fingertip to determine the tenderness. The foot will then be positioned into complete plantar flexion and gently fine-tuned by rotation until there is a reduction in tender point by at least 70%, and this position will be held for 90 seconds with 3 repetitions.
