Overhead Squat Assessment:

Manual Muscle Testing (MMT) for an Active Population:

  • Gluteus Maximus MMT and Modifications:
    • A common result indicating dysfunction is strong with compensation (excessive lumbar extension, knee flexion, and/or adduction = synergistic dominance of erector spinae, biceps femoris and/or adductor magnus), or a “bounce” is noted. A “bounce” results in the individual giving way upon initial application of manual resistance followed by an active attempt to regain position. This may indicate an inability to quickly recruit this muscle resulting in latent firing during dynamic motion.
    • Provocative testing –
