Limitations and future scope
proprioceptive and vestibular training
This study has a few methodological limitations that should be disclosed. First, the findings from this study are specific to 15–18-year-old deaf male adolescents. More research is needed to identify whether our findings can be generalized to deaf female adolescents, in this age range. Second, the effects of PT can be compared with vestibular exercises; because both proprioceptive and vestibular training programs are sensory systems training programs, therefore, the comparison of these two types of training can be done to determine which training is more effective on gait parameters of deaf adolescents. Third, there was no blinding in the evaluation of the variables and blinding of evaluators; so, it is suggested that future researches consider this limitation. Fours, due to the lack of assessment of the vestibular function of the deaf adolescents, the results presented study do not allow us to conclude anything regarding the vestibular function of deaf adolescents. Finally, determining different times for retention after the completion of both training interventions could enhance our understanding of the effectiveness of training on gait parameters.
