Gluteus maximus Gait, Lordotic Gait, lurching gait; when gluteus maximus muscle is weak

Gait Patterns: Gluteus Maximus, Lordotic, and Lurching These three gait types are linked to muscle weakness or compensatory mechanisms in walking. Let’s break them down clearly: 1. Gluteus Maximus Gait (aka “Lurching Gait”) Cause: Weakness or paralysis of the gluteus maximus (primary hip extensor). Pattern: The person thrusts their trunk backward at heel strike to maintain hip extension. This backward “lurch” reduces the need for gluteus maximus activity. Appearance: Noticeable backward lean of the trunk during stance phase. Clinical Note: Often seen in neuromuscular disorders or after hip surgery. 2. Lordotic Gait Cause: Weakness of hip flexors (e.g., iliopsoas) or compensatory posture. Pattern: The person exaggerates lumbar lordosis (arching of the lower back). This helps bring the leg forward when hip flexion is weak. Appearance: Excessive sway of the lower back, pelvis tilted forward. Clinical Note: Common in muscular dystrophy or hip flexor weakness. 3. Lurching Gait Cause: Often synonymous with gluteus maximus gait, but sometimes used more broadly to describe compensatory trunk movements. Pattern: Trunk shifts or “lurches” to maintain balance and propulsion. Can be backward (gluteus maximus weakness) or sideways (Trendelenburg-type compensation). Appearance: Sudden, noticeable trunk movements during walking. Clinical Note: The term “lurching gait” is sometimes used interchangeably with gluteus maximus gait, but context matters. ✅ In short: Gluteus maximus gait = backward trunk lurch at heel strike. Lordotic gait = exaggerated lumbar lordosis to compensate for hip flexor weakness. Lurching gait = general term for trunk shifts, often overlapping with gluteus maximus gait #Gait
