Upper Limb Rotation Test: Validity and Reliability
ℹ️ℹ️
INTRO:
Several risk factors exist for throwing-related shoulder injuries, such as:
- Glenohumeral Internal Rotation Deficit (GIRD).
- Reduced total range of motion.
- Scapular dyskinesia.
- External/internal rotation strength ratio imbalances.
ℹ️
Physical performance tests (PPTs) provide a a functional status of the athlete’s upper extremity.
ℹ️
These PPTs are routinely used for:
- Injury prediction.
- Performance enhancement.
- Post-rehabilitation outcome measures.
ℹ️
Some PPTs have been developed for closed kinetic chain (CKC), such as:
Closed Kinetic Chain Upper Extremity Stability Test (CKCUEST). –
and –
Open kinetic chain (OKC), such as:
Seated medicine ball throw (SMBT).
ℹ️
Many PPTs currently used do not fully address specific requirements of overhead throwing, including:
A combination of OKC, CKC and a trunk rotation as well as 90°/90° shoulder position .
ℹ️
To comply with this need, the Upper Limb Rotation Test (ULRT), may be better, as it includes:
- Weight bearing.
- Shoulder motor control and stability.
- Involves the entire kinetic chain.
- Places the shoulder in 90°/90° position.
ℹ️
Decleve et al. (2020) test 91 healthy adults to determine the reliability of the ULRT and examined the correlations with two widely used PPTs:
CKCUEST
SMBT
–
and .
–
2 clinical measurements:
Shoulder isometric rotational strength.
Trunk rotational range of motion (SRT).
✅✅
MAIN FINDINGS:
High relative reliability values and clinically acceptable absolute reliability values were found.
✅
The ULRT showed moderate correlations with the CKCUEST and SMBT.
✅
The ULRT is a good physical performance test of:
- OKC
- CKC
- Trunk rotation
- 90°/90° shoulder position.
📊📊
CONCLUSIONS:
- Very high intra-session reliability.
- High reliability for test-retest.
- Clinically acceptable absolute reliability.
📊
Moderately correlated with:
CKCUEST and SMBT.
📊
Poorly correlated with:
Shoulder isometric rotational strength and SRT. .
