RECRUITMENT
Our patient recruitment and retention were negatively affected by the COVID-19 pandemic. We considered using telehealth methods; however, we ultimately decided against these to maintain equal patient–personnel contact among both groups. MoveTrain may be performed using video and webcast software; however, JtMob requires the patient to be with the physical therapist.Recent consensus statements recommend the iHOT-33 or the Copenhagen Hip and Groin Outcome Score (HAGOS) for use as patient-reported outcomes measures in patients with HRGP.Given the paucity of evidence related to the HEP that should be recommended to complement joint mobilization, we developed the HEP based on clinical expertise, which may limit the internal and external validity of the study. It is unlikely 1 single mechanism will explain a patient’s response to joint mobilization. The proposed mechanisms underlying the therapeutic effects of manual therapy and the interactions of these mechanisms are complex,We developed this pilot RCT to assess the feasibility of completing a larger RCT to assess the effects of JtMob and MoveTrain. The COVID-19 pandemic limited our patient recruitment, patient retention, and treatment session attendance. Nevertheless, our enrollment rate prior to the pandemic and our overall retention rate suggests that a larger trial may be feasible, barring future pandemics. We established high treatment fidelity among treatment providers and patients. Based on our preliminary findings, 12 weeks of rehabilitation, either JtMob or MoveTrain, is safe and may result in improvements in patient-reported pain and activity limitations. Further investigation is needed to determine the long-term effects of each treatment and if specific patient factors are associated with treatment prognosis.
