Outcome measures

• Manual muscle testing:

  • Dynamometer favoured over manual testing
  • Dynamometer shown to identify deficits > 20% strength in the adductor muscle groups
• Copenhagen hip and groin outcome score (HAGOS):

  • Valid and reliable for measuring the hip and groin pain
  • Free, simple to use
• • Patient specific function scale (PSFS)
  • Visual analogue scale for pain, e.g.4/10
