Modeling the walking patterns of Reciprocating Gait Orthosis users with a novel Lower Limb Paralysis Simulator

Area of Science:

• Biomechanics
• Rehabilitation Engineering

Background:

• Reciprocating Gait Orthosis (RGO) use requires specific gait adaptations.
• Modeling RGO-assisted gait in able-bodied individuals can aid research and training.

Purpose of the Study:

• To evaluate if a novel mechanical Lower Limb Paralysis Simulator (LLPS) can replicate RGO user gait characteristics.
• To assess the validity of the LLPS as a tool for studying RGO-assisted ambulation.

Main Methods:

• Development of a mechanical Lower Limb Paralysis Simulator (LLPS).
• Training five able-bodied participants to ambulate using the LLPS.
• Conducting motion gait analysis on participants using the LLPS.

Main Results:

• Able-bodied subjects using the LLPS exhibited gait patterns consistent with those of RGO users.
• The LLPS successfully simulated key characteristics of RGO-assisted gait.

Conclusions:

• The mechanical Lower Limb Paralysis Simulator (LLPS) is a viable tool for modeling Reciprocating Gait Orthosis (RGO) user gait.
• This simulator can facilitate research and understanding of gait impairments and assistive device use.
