Design: Epidemiological study of the prevalence of hand OA in patients with knee osteoarthritis. The Stanford Health Assessment Questionnaire instruments (HAQ);Disabilities of the Arm, Shoulder and Hand* (DASH);grip strength;and finger pinch were utilized, and the upper limbs symptoms were verified at baseline and one year following the educational program. Results: The prevalence of hOA was 23.7% at baseline and 47.4% at one year (incidence of 31.8% per year). The HAQ indicated that patients who did not alter or increased their BMI experienced worsened global strength, whereas patients who reduced BMI improved global strength (p = 0.041). Patients with higher initial BMIs experienced less improvement in the HAQ (r = -0.148, p = 0.041). The DASH results improved, but the right and left tripod grip worsened in all patients, irrespective of BMI change (p < 0.05) or symptoms at baseline and reassessment (p < 0.05). Pinch strength (right and left tripod and left pulp-pulp) was higher in patients without symptoms at baseline (p = 0.048, p = 0.045 and 0.033, respectively). Conclusions: The prevalence of hand OA increased for patients with OA undergoing an educational program irrespective of improved upper function and regardless of BMI change. Patients who decreased their BMI improved their global strength.展开更多

Design: Randomized controlled usability and feasibility study. Setting: Rehabilitation laboratories at two regional medical centers. Participants: Individuals with knee osteoarthritis undergoing unilateral TKA (APP group: N = 26;mean age, 67.0 ± 8.2 y;CONTROL group: N = 31;mean age, 64.7 ± 7.7 y). Interventions: This study assessed the user experience of a downloadable app to guide 30 days of home exercises and instruction after TKA and compared exploratory outcomes to a group using paper handouts. Main Outcome Measures: The System Usability Scale (SUS) score was used to assess patient usability experience. Raw SUS scores were dichotomized (≥72% or <72%) to determine app usability against a 75% a priori criterion for mean APP group score. Feasibility for app use was similarly evaluated in the APP group only through a priori criteria applied to computing device ownership and study use, to the absence of technology-based barriers to participation, and to completion of app-based testing. Exploratory measures compared change from baseline to 30 days for functional and patient-reported outcomes between APP and CONTROL. Results: The APP group’s mean SUS score of 79.2% at 30 days exceeded the 75% threshold for good usability. The app met the predetermined a priori feasibility criteria for absence of technology-based barriers to participation (75% of participants) and completion of app-based testing (91.3% of participants). Personal computing devices were used by 71.4% of APP participants, which was below the 75% a priori feasibility criterion. No differences between the APP and CONTROL groups were observed for functional or patient-reported outcomes. Conclusions: The app-based platform met the a priori criteria for usability for 79% of APP participants. Our findings suggest that app-based, avatar-guided home exercise after TKA has acceptable usability and feasibility. The app-guided patient assessment capability also demonstrates preliminary feasibility for guiding and administering functional and self-reported outcomes assessments.展开更多
