Identifying Gait Pathology After Acl Reconstruction Using Temporal Characteristics Of Kinetics And Electromyography, Naoaki Ito, Jacob J. Capin, Ashutosh Khandha, Thomas S. Buchanan, Lynn Snyder-Mackler

Physical Therapy Faculty Research and Publications

Purpose

Asymmetrical gait mechanics after anterior cruciate ligament reconstruction (ACLR) are associated with the development of posttraumatic knee osteoarthritis. Current measures of gait mechanics have focused heavily on peak magnitudes of knee kinematics, kinetics, and joint contact forces but have seldom considered the rate of knee loading, cumulative knee load, or the timing of motor input surrounding peaks. The purpose of this study was to introduce and describe novel metrics of gait using temporal characteristics of kinetics and EMG to identify neuromuscular deficits of the quadriceps in patients after ACLR.

Methods

Gait mechanics were assessed 6 months (n = …

Objective

To evaluate the preferences of patients with osteoarthritis for treatment.

Methods

A discrete-choice experiment was conducted among adult OA patients who were presented with 12 choice sets of two treatment options and asked in each to select the treatment they would prefer. Based on literature reviews, expert consultation, patient survey and expert meeting, treatment options were characterized by seven attributes: improvement in pain, improvement in walking, ability to manage domestic activities, ability to manage social activities, improvement in overall energy and well-being, risk of moderate/severe side effects and impact on disease progression. Random parameters logit model was used to …

Preferences For Physical Activity: A Conjoint Analysis Involving People With Chronic Knee Pain, Daniel Pinto, Ulf Bockenholt, Jungwha Lee, Rowland W. Chang, Leena Sharma, Daniel J. Finn, Allen W. Heinemann, Jane Louise Holl, Paul D. Hansen

Physical Therapy Faculty Research and Publications

Objective

To investigate individual preferences for physical activity (PA) attributes in adults with chronic knee pain, to identify clusters of individuals with similar preferences, and to identify whether individuals in these clusters differ by their demographic and health characteristics.

Design

An adaptive conjoint analysis (ACA) was conducted using the Potentially All Pairwise RanKings of all possible Alternatives (PAPRIKA) method to determine preference weights representing the relative importance of six PA attributes. Cluster analysis was performed to identify clusters of participants with similar weights. Chi-square and ANOVA were used to assess differences in individual characteristics by cluster. Multinomial logistic regression was …

A Randomized Trial Of A Motivational Interviewing Intervention To Increase Lifestyle Physical Activity And Improve Self-Reported Function In Adults With Arthritis, Abigail L. Gilbert, Jungwha Lee, Linda S. Ehrlich-Jones, Pamela A. Semanik, Jing Song, Christine A. Pellegrini, Daniel Pinto, Dorothy D. Dunlop, Rowland W. Chang

Physical Therapy Faculty Research and Publications

Background

Arthritis is a leading cause of chronic pain and functional limitations. Exercise is beneficial for improving strength and function and decreasing pain. We evaluated the effect of a motivational interviewing-based lifestyle physical activity intervention on self-reported physical function in adults with knee osteoarthritis (KOA) or rheumatoid arthritis (RA).

Methods

Participants were randomized to intervention or control. Control participants received a brief physician recommendation to increase physical activity to meet national guidelines. Intervention participants received the same brief baseline physician recommendation in addition to motivational interviewing sessions at baseline, 3, 6, and 12 months. These sessions focused on facilitating individualized …

Association Between Sedentary Time And Quality Of Life From The Osteoarthritis Initiative: Who Might Benefit Most From Treatment?, Daniel Pinto, Jing Song, Jungwha Lee, Rowland W. Chang, Pamela A. Semanik, Linda S. Ehrlich-Jones, Christine A. Pellegrini, Dorothy D. Dunlop

Physical Therapy Faculty Research and Publications

Objective

To investigate the relationship between sedentary behavior and quality-adjusted life years (QALYs) among participants in the Osteoarthritis Initiative.

Design

Longitudinal, observational design.

Setting

Osteoarthritis Initiative cohort.

Participants

Individuals (N=1794) from a prospective, multicenter longitudinal cohort were classified into quantile groups based on average daily sedentary time (most sedentary, quartile 1 [Q1] ≥11.6h; 10.7h≤ Q2

Interventions

Not applicable.

Main Outcome Measures

Individual QALYs were estimated over 2 years from the area under the curve of health-related utility scores derived from the Medical Outcomes Study 12-Item Short-Form Health Survey versus time. The relationship between baseline sedentary behavior and median 2-year QALYs …
