The Authors of “Medical-Grade Physical Activity Monitoring
for Measuring Step Count and Moderate-to-Vigorous Physical
Activity: Validity and Reliability Study” (JMIR Mhealth Uhealth
2018;6(9):e10706) mistakenly represented the Yamax
Digiwalker in the Discussion section. Unlike some of Yamax’s
newer devices (ie, Yamax EX-510), the Yamax Digiwalker is
a spring-levered pedometer and not a piezoelectric pedometer.
Thus, the following sentence has been removed from the
Discussion:
Similar to the PiezoRx, the Yamax also uses a
piezoelectric sensor, which is consistent with this
study.
The correction will appear in the online version of the paper
on the JMIR website on January 3, 2019, together with the
publication of this correction notice. Because this was made
after submission to PubMed, PubMed Central, and other full-text
repositories, the corrected article also has been resubmitted to
those repositories.

Assessing Physical Activity After ACL Injury: Moving Beyond Return to Sport
Article
  • Jun 2021
Context: Return to sport is widely utilized by sports medicine researchers and clinicians as a primary outcome of interest for successful recovery when working with young patients who have undergone anterior cruciate ligament (ACL) reconstruction (ACLR). While return-to-sport outcomes are effective at tracking progress post-ACLR, they are limited because they do not necessarily capture physical activity (PA) engagement, which is important to maintain knee joint health and reduce the risk of noncommunicable diseases. Therefore, there is a critical need (1) to describe current PA participation and measurement recommendations; (2) to appraise common PA measurement approaches, including patient-reported outcomes and device-based methodologies; and (3) to provide clinical recommendations for future evaluation. Evidence acquisition: Reports of patient-reported or device-based PA in patients with ACL injury were acquired and summarized based on a PubMed search (2000 through July 2020). Search terms included physical activity OR activity AND anterior cruciate ligament OR ACL. Study design: Clinical review. Level of evidence: Level 5. Results: We highlight that (1) individuals with ACLR are 2.36 times less likely to meet the US Department of Health and Human Services PA recommendations even when reporting successful return to sport, (2) common patient-reported PA assessments have significant limitations in the data that can be derived, and (3) alternative patient-reported and device-based assessments may provide improved assessment of PA in this patient population. Conclusion: Clinicians and researchers have relied on return to sport status or self-reported PA participation via surveys. These approaches are not consistent with current recommendations for PA assessment and do not allow for comparison with contemporary PA recommendations or guidelines. Return to sport, patient-reported outcome measures, and device-based assessment approaches should be used in complementary manners to comprehensively assess PA participation after ACLR. However, appropriate techniques should be used when assessing PA in adult and adolescent populations.
