Eligibility

Inclusion criteria

Inclusion criteria: • Traumatic Complete Paraplegia with less than two years of post injury • Lower limb joint passive range of motion should be within normal limits • Age group : 18 years and above • Lower limb muscle spasticity less than Grade 2 in MAS • Optimistic and motivated attitude and acceptance of technology

Exclusion criteria

Exclusion criteria: • Chronic infective disease • Previous history of transient ischemic attacks. • Chronic kidney, heart or lung disease • History of acute Deep Vein Thrombosis • History of active Heterotopic Ossification in hip or knee joints • Poor skin condition in electrode areas • Allergy to adhesive materials • Pregnancy • Contractures limiting joint movement • Subjects with Pacemakers and metal implants in the lower limbs

Design outcomes

Primary

MeasureTime frame
â?¢ To observe the torque generated by the muscle groups when stimulated supramaximal. It is hypothesized that the joint torques generated due to artificial stimulation would be approximately 25% of the required torque for a given task. â?¢ Map the torque generated to joint angles and stimulation intensity Timepoint: Forces would be recorded during the intervention and post analyzed. Trials would be repeated on two alternate days to asscertain repeatibility.

Secondary

MeasureTime frame
Map the torque generated to joint angles and stimulation intensity Timepoint: data would be analyzed after all the recordings are complete
