New evidence summary: Selective Percutaneous Myofascial Lengthening

Our newest 'What's The Evidence' summary looks at the evidence for Selective Percutaneous Myofascial Lengthening for children with cerebral palsy. 

Key findings:

  • Selective Percutaneous Myofascial Lengthening (SPML) is a surgical procedure that aims to lengthen certain muscles, or to reduce tone in the muscles.
  • The procedure involves making small cuts through the skin to reach and divide the connective tissue around muscles.
  • Advocates claim that SPML will improve the ability of children with cerebral palsy to sit, stand or walk.
  • Only one published, peer-reviewed study was identified that looked specifically at the effectiveness of Selective Percutaneous Myofascial Lengthening.
  • There is currently no high quality evidence for the effectiveness and safety of this surgery for children with cerebral palsy.
