Do dancers score differently than other athletes on the Y Balance Test Lower Quarter?

Researchers found that Y Balance Test Lower Quarter performance in collegiate dancers was superior to other athletes, with dancers demonstrating a mean composite reach score of 105%. “This research supports the findings of previous studies by demonstrating dancers’ superior dynamic balance ability compared to other athletes, thus indicating the need for YBT-LQ normative values to be established for dancers.” (Cole et al)

Do modifiable risk factors for injury still remain at return to sport in those with ACL reconstructions?

Another group of researchers (see previous CSM research post for the other research) found that  deficits are present in athletes who return to sport post-ACLR. In particular, the star excursion balance test anterior reach asymmetry and prone heel height difference (a method to identify decreased knee extension ROM) were present at return to sport and clinicians “should consider using the SEBT to identify post-ACLR athletes who may be at increased risk for injury and decreased joint health.” (Stanley et al)

Does pain with clearing or movement tests predict injury in healthy active duty soldiers?

You bet it does!

In a cohort of 1455, “pain was present on 207 (14.2%) FMS movement tests, 176 (13.5%) FMS clearing tests, 56 (3.8%) YBT-LQ, 96 (6.6%) YBT-UQ, 93 (6.4%) 6-m hop tests, 80 (5.5%) triple crossover hop tests, and 13 (0.9%) ankle dorsiflexion. Pain at baseline movement testing was associated (P =.001) with future injury. The odds ratio of being injured in the upcoming year based on pain on movement tests was 2.0 (95% confidence interval: 1.6, 2.5). The odds ratio of being injured in the upcoming year based on prior history of injury was 2.1 (95% confidence interval: 1.7, 2.6).” (Teyhen et al)

CSM 2014

While there has been a lot of great information presented, here are a few pearls from the first day:

  • Not surprisingly, wrestlers perform better than baseball players on the Upper Quarter Y Balance Test.  Just like the Lower Quarter Y Balance Test, norms and risk cut points need to be gender, age, sport/activity specific. Want more info in need for population specific norms CLICK HERE


  • Shoulder flexion ROM limitation may be a risk factor for injury in professional baseball pitchers. This was not presented as formal research, but was briefly mentioned as an upcoming publication during the morning throwing athlete session. I am intrigued.


  • Asymmetrical Lower Quarter Y Balance Test at 12 weeks status post ACL reconstruction identifies those who won’t pass hop testing at time of return to sport. This is important as it can identify early those who may need different rehab strategies before higher level (e.g. plyometric) activity can be performed
