PRI Gait Analysis of the Accelerated “Asymmetrical” American
1. The left foot goes through a toe-out gait pattern at early push-off compared to the right. Secondary to poor abductor co-contraction of adductors and anterior gluteus medius.
2. The right lower extremity externally rotates more overall than the left. During swing because of overactive iliacus and during stance because of innominate orientation of legs and trunk to the right.
3. The right heel lifts early at mid-stance compared to the left and at push-off. Secondary to longer interval of right weight acceptance and trunk glide and longer shorter swing and ‘stride’ with left leg.
4. The femurs significantly internally rotate at push-off. At late mid stance and trunk glide phases innominates are forwardly rotated too much contributing to FA IR orientation or position. Especially seen in hyperextended individuals.
5. There appears to be a higher ‘active’ mid foot arch on the right at mid stance. Secondary to overactive, shortened strong right adductor influence on foot and ankle.
6. No sufficient resupination of the left foot occurs after midstance to stabilize or “lock” the tarsus in the sagittal plane and allow for efficient propulsion. Contributed by weak right acetabular femoral external rotational strength.
7. The right 1st metatarsal is not secure in plantar-flexion against the ground during forefoot loading. Contributed by C.O.G. over-distributed to the right and overactive left TFL during swing.
8. The right 1st MTP joint does not dorsiflex freely for forward gait progression without compensatory dorsiflexion from smaller toes and shifting of COG to the right. Secondary to forefoot and possibly rearfoot varus and overactive posterior gluteus medius and iliacus.
9. The right arm does not move forward upon right toe-off. Secondary to poor left lateral abdominal integration and overactive right thoracic abductors reinforcing right arm adduction.
10. The left shoulder does not drop upon left toe-off. Contributed by weak left gluteus medius and left lateral abdominals at late mid stance or trunk glide.
