Introduction[edit | edit source]
Due to resource constraints, most clinical set-ups do not have access to equipment for instrumented gait analysis. Thus, the observational gait analysis (OGA) is a suitable alternative in most clinical applications.[1]
Method of use[edit | edit source]
The subject can be assessed through live observation or by videotaping the subject and analyzing the recorded footage. The latter might be beneficial in certain instances where repeated gait cycles may induce fatigue in the subject and impede the reliability of results.[2]
There are two methods to scoring the OGA:
- Graded
- 0 = Normal Gait
- + = Just noticeably abnormal gait
- ++= Very noticeably abnormal gait
- Binary
- Present
- Absent
