Intervention / Comparator Agent  
Type  Name  Details 
Intervention  combined plyometrics and, balance training And Conventional physiotherapy for 6 weeks  the training programs for the balance and plyometric in adjunct to conventional physiotherapy for three groups. three groups were trained for 3 days/week over 6 weeks. The total training time for each session was 20 minutes. To prevent injury and to prepare the participants promptly for the exercises, both groups performed the same warm-up and cool down. Each week contained 4 types of exercises, and the difficulty level of the exercises progressed over the weeks.  
Intervention  combined plyometrics and balance training with eccentric resistance training and conventional physiotherapy training for 6 weeks  in group b training program for combined plyometrics with balance and eccentric resistance training was given. The procedures were based on a 6-week resistance band protocol. Participants were instructed to use only the involved ankle joint and to maintain a consistent pace of approximately 3 to 5 seconds per repetition throughout the full range of motion. Each week, participants progressed by increasing the number of sets, band resistance.  
Comparator Agent  conventional physiotherapy training for 6 weeks  The routine rehabilitation training consisted of warm-up activities, resistance training exercises, and muscle stretching and relaxation. Training was performed once a day, and each training session was performed on alternate days. The warm-up activities lasted five minutes each and consisted of active joint movements. Resistance training was assisted by elastic bands, and under the guidance of the therapist, resistance training was performed in each direction of ankle plantarflexion, ankle dorsiflexion, ankle inversion, ankle eversion, etc., with 10 times in each direction as one group, making a total of three groups. Muscle stretching and relaxation was performed after each training session, in the form of passive stretching of ankle plantarflexion, ankle dorsiflexion, ankle inversion and ankle eversion muscle groups for 30 s each time, a total of three groups.

Brief Summary   1. Prevalence and Impact: Acute lateral ankle sprains are a commonly incurred injury by individuals who partake in field, court, sports. 10-61% of badminton injuries were ankle sprains. In the longer term, lateral ankle sprains lead to chronic ankle instability. The persistent recurrence highlights the need for more effective interventions, especially in populations of high-demand athletes. 

 2.Available solution plyometric training was an effective program for enhancing static and dynamic balance and increasing ankle joint stability among individuals with Functional ankle instability FAI. Restoring dynamic balance is also crucial for returning to regular activities after an ankle instability. Balance training could improve the dynamics of balance as demonstrated by the improved reach distances in the anterior, posteromedial, and posterolateral directions after 6 weeks of training. Dynamic support through eccentric muscle actions provided from both the peroneal and tibialis anterior muscles is one of the key components in the prevention of a lateral ankle sprain when the ankle is forced into plantar flexion/inversion. Therefore, eccentric strengthening exercises of the ankle evertors and even the dorsiflexors seem to be important to be able to resist an inversion sprain.

 3 Limitations: The researchers identified as knowledge gap In study about, combination between plyometric and balance training programs and other types of training such as power, strength, or endurance exercise were not included so it is a need to be explored. Another limitation in study was Strength-training and multicomponent rehabilitation studies should continue to use clinically applicable dependent variables to improve rehabilitation protocols and better serve the patient and clinician. The study aims to address a critical need in understanding the impact of plyometric training and balance training versus eccentric exercise training in adjunct to conventional physiotherapy for ankle instability in badminton athletes. The research is crucial for enhancing rehabilitation strategies, training protocols and ultimately improving performance and injury prevention strategies for badminton players who faces challenges related to ankle instability.
