- 1. Managing calf injuries and RTP considerations Seth O’Neill @seth0neill so59@leicester.ac.uk
- 2. Epidemiology of Calf injuries • 4th most common injury • 4% of all injuries • 14%-16% of all muscle injuries (FC Barcelona 2009) • 14.7 days lost – 13% are >28days • 13% re-injure • Older players more frequently injured • Last 15 minutes of game key period
- 3. Older players more frequently injured Age
- 4. Why does the Calf get injured? @seth0neill so59@leicester.ac.uk
- 6. Soleus contributes 50% of total vertical support force
- 7. Soleus 52% Med Gas 32% Lat Gas 16% Albracht et al 2008
- 9. MTJ RTP earlier than MTC
- 10. Which muscle? • 66% are solitary muscles • Isolated tears = Gastroc : Soleus 49% : 46% • 34% are combination injuries • Soleus not normally reported • Plantaris and Deep muscles occasionally involved @seth0neill so59@leicester.ac.uk
- 11. What else can Soleus do? • Control knee flexion • Control tibial translation Therefore may link with ACL and Meniscal injuries and be important pre/post injury • Control Achilles loads and is implicated in tendinopathy Sherbody et al 2003, Mokhtarzadeh 2013, Fleming 2001 @seth0neill so59@leicester.ac.uk
- 12. What we can learn from other muscles • Strength seems important • Monitoring of strength may be predictive • Strength may inform RTP • Fascicle length and pennation angle may be key • Injured players may respond differently to strength changing @seth0neill so59@leicester.ac.uk
- 13. Preliminary data (caution N=9 in each group) 96% 206% P .00001Rehab needs to be heavy @seth0neill so59@leicester.ac.uk
- 14. Rehab, RTP and prevention • Identify which muscle and which location • Strength >BW • Endurance • Rate of force development • Velocity @seth0neill so59@leicester.ac.uk
- 15. Summary • Calf injuries are frequent, produce loss of play, and may link to other pathologies – e.g. ACL and AT • Consider intramuscular tendon injuries specifically Soleus. • Beware older (senior+expensive) player • Late game situations • Rehab heavy @seth0neill so59@leicester.ac.uk
Editor's Notes
- A quick examination of Physiorooms.com data for current injured premiership players suggests an 8% prevelance as of today. Carles pedrets timeloss is mean of 29 days. Think senior expensive/key players UNDER –REPORTING OF SOLEUS.
- 3.5 to 9meteres per second.
- 59 subjects
- Mostly comes from Adductors and Hamstring data.
- P .00001 No pain during testing. ICC of 0.82 or 0.74 dependent on dominent leg and MDC of approx 7%
