Adults (18-60 years) who came as new pts to a hip clinic for young adults or who were participating in a follow-up after a hip-preserving treatment for diagnoses including, but not limited to: chondral defects, trauma, FAI, labral tears, early OA, instability, loose bodies, Perthes disease, AVN, SCFE, and dysplasia, were used to develop this new (shortened) outcome measure.
Determined using standardized effect size:
- Large responsiveness, 0.98 (95% CI, 0.67-1.28) for iHOT-12
- Large responsiveness, 1.03 (95% CI, 0.70-1.36) for iHOT-33
Jónasson et al (2014)
502 Swedish men and women age 15-75 (average age 37) with femoroacetabular impingement.
“The changes in the GPE score between baseline and the 4-month follow-up were in agreement with the SRM and ES results, indicating good responsiveness by the iHOT12-S.”
Hip arthroscopic surgery for intra-articular hip lesion:
Age 16-80 who underwent hip arthroscopic surgery for intra-articular hip lesion performed by one specific orthopedic surgeon in past 12-24 months.
Correlation with Global Rating of Change (GRC): r =0 .57; p < 0.001. Moderate responsiveness, effect Size = 0.22. Relationship considered if r > 0.40 and significance if p < .05.
A variety of symptomatic hip conditions:
Young, active patients (aged 18 to 60 years, Tegner activity level > 4) presenting with a variety of symptomatic hip conditions.
The mean change in score was 33 with a SD of 19.3. Responsiveness was determined using several different measures, including a comparison of baseline and 6-month data with a paired t test, standardized effect size, standardized response mean, and responsiveness ratio.
For the comparison of baseline and 6-month data, the paired t test showed highly significant differences, with p < .01. The standardized mean response was 1.7, standardized effect size is 2.0--Large responsiveness, responsiveness ratio was 6.7.
