Screening the lunge pattern

Deviations from normal lunge pattern

There are many common deviations from the normal lunge pattern.

Table 1 describes common deviations from a side view that have been observed in club and professional Rugby Union players.

Deviation from normal pattern - side view with hands on hips
Possible imbalances
Ankle
  • Lead leg: heel rises as player moves forward
  • Trail leg: foot rotates outwards
  • Lead leg: Tight gastrocnemius and/or soleus
  • Trail leg: Tight peroneals
Knee
  • Lead leg: knee moves forward beyond toes*
  • Trail leg 1: knee moves outwards (abducts)
  • Trail leg 2: excessive extension of trail leg accompanying hyper extension of lumbar spine
  • Lead leg: Poor activation of gluteal muscles, tight quadriceps, underactive vastusmedialis, limited hip and/or ankle mobility
  • Trail leg 1: Tight quadriceps, IT Band*
  • Trail leg 2: Excessive lumbar lordosis
Hip
  • Hips and knee do not reach a parallel to floor position
  • Hip internal/external rotation may be limited. Issues pertaining to the lumbar spine are also relevant here
Lumbar spine
  • Flexion (curve), hyper extension (excessive bending forward at lumbar spine)
  • Flexed lumbar spine: weak abdominals and poor activation of gluteals, tight hip flexors and/or quadriceps
  • Hyper extension: Tight hip flexors and/or quadriceps
Thoracic spine
  • Flexion of T-spine with appearance of rounded shoulders
  • Poor stability in T-spine, tight pectoral muscles
Cervical spine and head
  • Extension of cervical spine – a forward head is the result
  • Tightness and dominance of extensors (including sternocleidomastoid) over deep lying flexor muscles
Head
  • Gaze lowered and eye and centre of ear not horizontal to floor
  • As in cervical spine and head imbalances

*A knee movement beyond the toes is controversial. Please see below for more detailed explanation.

Table 1. Common deviations from the normal forward lunge pattern. *ITB = Iliotibial Band (band of tissue on outside of thigh from hip to knee).

The common deviations from a normal forward lunge pattern are summarised in Table 1. Note we also illustrate some of these deviations in Table 3 and 4. Please take the time to inspect these deviations.
