Although 40 assessment tools are described in the literature, very few
of them have been correctly validated. The Standardized Index of Shoulder
Function (FI2S) encompasses pain, mobility, strength and function. The aim of
this work is to describe the FI2S and to study its construct validity,
reliability and responsiveness to change. PATIENTS: Fifty-nine patients with
non-surgical (rotator cuff lesions, frozen shoulders, osteoarthritis) or
post-surgical (acromioplasty, repairs of rotator cuff tears, arthroplasty)
shoulder disorders were included. METHODS: The FI2S was compared with the
Disabilities of the Arm, Shoulder and Hand questionnaire (DASH), with the
Constant-Murley Score (CMS), and with a visual analogue scale for pain. RESULTS:
Inter-test reliability and inter-rater reliability are excellent, with
intra-class correlation coefficient of 0.93 (0.88-0.96) and 0.94 (0.90-0.96),
respectively. Under a convergent hypothesis, the Spearman's correlation
coefficients with the CMS and DASH score are 0.91 (p < 0.0001) and -0.64 (p <
0.0001), respectively. Correlations between the FI2S and the CMS are excellent
for mobility and strength, but moderate for pain and functional capacities. Under
a divergent hypothesis, no correlation is observed between the FI2S total score
and age. Responsiveness to change is excellent. CONCLUSION:
The FI2S appears to
be a proper assessment tool for pain, mobility, strength and function in shoulder
disorders, easy to administer and of good metric value.
