The primary objective within the current study is to compare the acute and chronic effects of eccentric training and IASTM on the dorsiflexion ROM. To reduce the risk of Achilles tendinopathy, stretching and eccentric (lengthening) exercises are postulated to improve ankle dorsiflexion. An eccentric exercise lengthens an active muscle while it is under load. Consequently, eccentric calf muscle exercises can also increase ankle dorsiflexion through an increase in calf muscle strength. For the above mentioned reasons, a combination of stretching exercises and eccentric (lengthening) exercises are suggested as preventive intervention to increase ankle dorsiflexion. The biggest goal of IASTM is to remove scar tissues and facilitate a return to normal function following soft tissue recovery. These Techniques, eccentric stretching and IASTM works towards bringing back the normal range of motion and strength, allowing individuals to regain mobility and return to their usual activities and we will find out the better option from these.

Ankle sprain is a traumatic injury that occurs to one or more of lateral ankle ligaments: anterior talofibular ligament, posterior talofibular ligament and calcaneofibular ligament. Ankle sprains are one of the most common musculoskeletal injuries. The ankle is the second most commonly injured body part during sports, with ankle sprains being the most common ankle injury. Instrument-Assisted Soft Tissue Mobilization (IASTM) is a type of soft tissue mobilization that uses rigid devices to increase the examination and treatment of soft tissues. According to recent studies, Instrument-Assisted Soft Tissue Mobilization (IASTM) is a new and highly trained myofascial technique that has gained favor in modern decades for treating soft-tissue ailments. To reduce the risk of Achilles tendinopathy, stretching and eccentric (lengthening) exercises are postulated to improve ankle dorsiflexion. An eccentric exercise lengthens an active muscle while it is under load.

Consequently, eccentric calf muscle exercises can also increase ankle dorsiflexion through an increase in calf muscle strength. For the above mentioned reasons, a combination of stretching exercises and eccentric (lengthening) exercises are suggested as preventive intervention to increase ankle dorsiflexion. Eccentric training is an alternative modality that also shows promise for inducing chronic improvement in ROM. In past years there has been different protocols to treat ankle sprain but this study will contribute to more effective method of treating ankle sprain, improving their recovery and also reducing the risk of re-injury. This study will potentially reduce healthcare costs associated with rehabilitation or the need of additional interventions. This study will have fast and more effective rehabilitation method which can boost the athlete performance, making it the treatment of choice for both athletes and sports teams.
