Clinical, gait and balance parameters after diagnostic obturator nerve block in patients with spasticity - a pre-post interventional study

This study expects to find out the functional improvement in hip adductor spasticity and the change in gait and balance parameters after obturator nerve block. Patients above 18 years of age will be enrolled for the study as per inclusion and exclusion criteria. All the patients will receive anti spasticity medications at stable doses throughout the study duration. Modified Ashworth Scale (MAS), Spasm Frequency Scale, R1 of Modified Tardieu Scale (knee flexed and extended) , Gait parameters and Balance parameters will be assessed immediately before the procedure. Clinical data for primary evaluation will be obtained by examination for Modified Ashworth Scale (MAS) of adductor group of muscles, Spasm Frequency Scale and R1 of Modified Tardieu Scale (both in knee flexed and extended condition). Spatiotemporal gait parameters will be collected by using the inertial motion sensor G-WALK (G-SENSOR II) of BTS gait analysis system which uses G-STUDIO software. Balance data will be collected by using the platform BALANCE SD which uses Balance System SD Software Update v4.0.18. USG guided Obturator nerve block will be done on the affected side using 1% lidocaine. 30 minutes after the procedure, the outcome variables will be assessed again.
