“…In our assessment of the content validity, or relevance, of the FAOS from the patient's perspective, we found that the FAOS was deemed relevant in all subscales with the exception of ADLs. Though the ADL subscale showed a trend toward relevance with a preoperative and postoperative average of 1.9, this finding is consistent with those found in recent FAOS validation studies for hallux valgus and flatfoot deformity [5,11]. Though it is, however, important to note that in the validation of Roos et al of the FAOS for ankle ligament reconstruction all subscales were deemed relevant [18].…”

“…This broad range does carry a concern regarding the ability of the FAOS to provide consistent assessment in both the immediate and long term. However, this concern is tempered by our reliability findings being consistent with those proven for the FAOS validation for both hallux valgus and flatfoot deformity with each also found the FAOS reliable on all subscales [5,11].…”

Background: There is a clear call for improved patient-centered outcomes. The Foot and Ankle Outcome Score (FAOS) is a region-specific patient-reported measure that has been validated for a number of foot and ankle diagnoses, but not hallux rigidus. Questions/Purposes: The aim of this study was to validate the FAOS in patients with hallux rigidus. Methods: From 2007 to 2013, 211 patients with hallux rigidus (HR) were included in the study. For the construct validity portion of the study, 125 patients completed a Short-Form 12 (SF-12) and FAOS survey. Forty additional HR patients were prospectively given questionnaires to assess the relevance of each FAOS question as it pertained to their HR. Reliability was assessed in 36 HR patients via administration of a second FAOS an average 1 month following the first. In 55 patients, preoperative and postoperative FAOS scores were compared to determine responsiveness.Results: All FAOS subscales demonstrated moderate correlation coefficients with the physical functioning, role physical, bodily pain, and physical health component scores of the SF-12, with all subscales demonstrating poor correlation with the SF-12 mental health-related domains. Content validity was high for all FAOS scores, with the exception of the daily activities subscale. All subscales achieved acceptable testretest reliability with correlation coefficients of ≥0.72. Furthermore, all subscales were rated as responsive to change in postoperative patients (p<0.001). Conclusion: This study demonstrates the acceptable construct and content validity, reliability, and responsiveness of the FAOS for hallux rigidus. Due to its broad applicability and proven validation across multiple foot and ankle pathologies, the FAOS represents a patient-centered outcome measure that can be reliably used for the assessment of patients with hallux rigidus.

“…Another thing to consider is improving the frequency of reporting sport-specific subscales of already validated questionnaires. The AOFAS[35], FAOS[59,153,154] and Thermann[43] scores include sports and activity sub-scales but these subscales are infrequently reported. Finally, though all terms implying sports participation of activity were included in this systematic review, it was noted that a number of different terms were used in the literature.…”

Return to play post-Achilles tendon rupture: a systematic review and meta-analysis of rate and measures of return to play

2016

Aim This systematic review and meta-analysis sought to identify return to play (RTP) rates following Achilles tendon rupture and evaluate what measures are used to determine RTP. Design Systematic review and meta-analysis. Studies were assessed for risk of bias and grouped based on repeatability of their measure of RTP determination. Data Sources PubMed, CINAHL, Web of Science, and Scopus databases were searched to identify potentially relevant articles. Eligibility criteria for selecting studies Studies reporting return to play/sport/sport activity in acute, closed Achilles tendon rupture were included. Results A total of 108 studies encompassing 6,506 patients were included for review. Eighty-five studies included a measure for determining RTP. The rate of RTP in all studies was 80% (CI95%: 75 – 85%). Studies with measures describing determination of RTP reported lower rates than studies without metrics described, with rates being significantly different between groups (p < 0.001). Conclusions Eighty percent of patients returned to play following Achilles tendon rupture, however, the return to play rates are dependent on the quality of the method used to measure RTP. To further understand RTP after Achilles tendon rupture, a standardised, reliable, and valid method is required.

“…However, the sports and recreation subscale of the FAOS showed little responsiveness to hallux valgus surgery. Ceiling effects were present for the ADL and sports subscale [45]. Data on MCID could not be traced [ Table 1].…”

“…It has been validated in the original manuscript, on patients after ankle ligament reconstruction. Recently it has been validated for patients with hallux valgus, showing acceptable reliability and responsiveness [45,46]. However, the sports and recreation subscale of the FAOS showed little responsiveness to hallux valgus surgery.…”
