SCS Rehabilitation & Return to Activity 2

Question 1

Which limb symmetry index (LSI) threshold on the single-leg hop test is most commonly cited as a minimum criterion before return to sport after ACL reconstruction?

Accepted Answer

90%

Answer

A limb symmetry index of ≥90% on hop testing is the most widely accepted minimum threshold before return to sport after ACL reconstruction.

Question 2

A baseball pitcher 6 weeks post-elbow UCL repair reports no pain at rest but pain with late-cocking phase throwing. Which rehabilitation principle is most violated if he is progressed to competitive throwing at this time?

Accepted Answer

Criteria-based progression

Answer

Criteria-based progression requires pain-free status and objective functional benchmarks to be met before advancing to higher-demand activities.

Question 3

During the late-stage rehabilitation of a soccer player with a hamstring strain, which test best assesses eccentric strength deficits that predict re-injury risk?

Accepted Answer

Nordic hamstring strength test

Answer

The Nordic hamstring strength test specifically evaluates eccentric hamstring strength, which is the most predictive factor of re-injury risk.

Question 4

A gymnast recovering from a Grade II lateral ankle sprain has regained full ROM and strength. Which rehabilitation component is most critical before return to full gymnastics training?

Accepted Answer

Proprioception and dynamic neuromuscular control

Answer

Proprioception and dynamic neuromuscular control are essential for ankle sprain rehabilitation because deficits in these areas drive recurrence rates.

Question 5

Which return-to-sport testing battery incorporates hop tests, quadriceps strength, and psychological readiness to form a composite RTS score?

Accepted Answer

Return to Sport after ACL reconstruction (ACL-RSI + LSI battery)

Answer

The ACL-RSI combined with limb symmetry index (LSI) hop and strength testing forms a multi-dimensional RTS battery addressing both physical and psychological readiness.
