Effect of Ballistic Training on Pain, Range of Motion and Strength in Phase II Rehabilitation of ACL Reconstruction: A Research Protocol of a Randomised Controlled Trial

Introduction: An Anterior Cruciate Ligament (ACL) injury produces a 5-40% reduction in quadriceps strength over time. Neuromuscular electrical stimulation is used to help the quadriceps muscle weaken after ACL surgery. The ACL is the primary stabiliser for anterior tibial displacement and the secondary stabiliser for tibial rotation; an ACL-deficient knee can result in devastating consequences like articular cartilage injuries, meniscus tears, functional instability, and the risk of early-onset osteoarthritis. Following an ACL injury, the goal of ACL restoration is to restore functional knee stability. Journals have indicated an increased interest in combining ACL restoration with extra-articular augmentation in recent years. Several studies have demonstrated that the extra reconstruction not only protects the graft from high loads, but also enhances lateral rotational control. In patients with sore joints after ACL reconstruction, cryotherapy can help by releasing endogenous opiates and decreasing nerve conduction velocity. Exercise performance for the physical qualities of strength and power, like many other sports activities, has a short time element for successful performance. As a result, these workouts are performed at the highest possible speed in the least amount of time.

Need for the study: There are many evidences that theraband exercises are essential for the patients with ACL reconstruction. Even in athletes, there are literature that proves ballistic training is essential for the patients with ACL reconstruction, but there is no literature for the ballistic training in normal population undergoing ACL reconstruction surgery. There is a strong need to perform a study and evaluate them.

Aim: To find out effectiveness of ballistic training in phase II rehabilitation on the patients with ACL reconstruction.

Materials and Methods: This randomised control trial will be conducted from May 2022 to May 2023 in the Outpatient and the Inpatient Department of Physiotherapy, Acharya Vinoba Bhave Rural Hospital, Sawangi (Meghe), Wardha, India, during which 100 patients with ACL reconstruction will be divided into two groups, one group will receive conventional therapy along with theraband exercises and another group will receive conventional therapy exercises along with ballistic training. Treatment will be given for eight weeks, five days in a week. The assessment will be done on day one of the treatment and at the end of treatment that is 8th week. Student’s t-test and Chi-square tests will be applied for statistical comparison.
