Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study involves an exoskeleton which is believed to increase quadriceps muscle strength in the rehabilitation phase after TKA and reduce the discharge the such patients in Extended care facility (ECF) . The purpose of this study is to access efficacy of the robotic exoskeleton device wrapped around the operated knee on patients

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

robotic exoskeleton device

Patients who are scheduled to be discharged to a ECF will be asked if they would want to use the exoskeleton device ( for which safety and comfort has been established) instead of going for ECF.

Group Type EXPERIMENTAL

Robotic exoskeleton device
