Collaborative-care Intervention to Promote Physical Activity After Total Knee Arthroplasty

2014-11-21 06:53:22 | BioPortfolio

Summary

The investigators have learned that knee replacement patients are not more physically active after surgery. This is true even though their pain is less compared to before surgery. This low level of physical activity is not healthy. It can increase the chances of weight gain, which can create other issues. It can also lessen physical function. Some studies have looked at physical activity feedback systems to increase how active people are. Studies have investigated face to face patient group meetings for this,too. These systems and meetings can increase physical activity. The investigators will study the effects of a physical activity monitors with group meetings after knee replacement. The investigators hypothesize that physical activity levels and physical function will increase. The investigators goal is to help knee replacement patients lead healthier lives and maintain or enhance their physical function.

Description

More than 650,000 total knee arthroplasties (TKAs) are performed annually to alleviate pain and disability associated with osteoarthritis (OA); a chronic, degenerative condition that compromises the quality of life of 37% of adults over age 60. With the aging of the population, an estimated 3.5 million TKAs will be performed annually by 2030. Despite improvements in pain and self-reported function, physical activity after TKA remains at pre-operative, sedentary levels (<5,000 steps/day). Physical activity in TKA confers powerful protective effects against common post-surgical sequelae including increased weight gain (mean=6.4 kg, 2 years post TKA), decreased functional performance, increased risk/progression of co-morbid conditions (e.g. type 2 diabetes mellitus, cardiovascular disease), and progression of knee and hip osteoarthritis which may necessitate additional joint replacement in the contralateral limb. An intervention aimed at improved self-management of physical activity may aid patients in overcoming habitual lifestyle patterns of low physical activity secondary to knee pain prior to TKA.

Recent investigations on the effects of real-time, user-friendly, electronic physical activity feedback (PAF) systems and face-to-face (FTF) patient group meetings aimed to promote self-management of physical activity suggest that such interventions can successfully increase physical activity. Therefore, the investigators propose a randomized, controlled trial to assess efficacy and feasibility of a physical activity intervention combined with FTF group meetings (PAF+FTF) initiated within one month of patients' discharge from outpatient rehabilitation for TKA compared to a control group receiving standard care (CON). This type of intervention is surprisingly novel to this patient population and is not common practice in rehabilitation following TKA.

Medical and Biotech [MESH] Definitions

A mechanism of communication with a physiological system for homeostasis, adaptation, etc. Physiological feedback is mediated through extensive feedback mechanisms that use physiological cues as feedback loop signals to control other systems.

A technique to self-regulate brain activities provided as a feedback in order to better control or enhance one's own performance, control or function. This is done by trying to bring brain activities into a range associated with a desired brain function or status.

Physical activity which is usually regular and done with the intention of improving or maintaining PHYSICAL FITNESS or HEALTH. Contrast with PHYSICAL EXERTION which is concerned largely with the physiologic and metabolic response to energy expenditure.

The time span between the beginning of physical activity by an individual and the termination because of exhaustion.

A mechanism of information stimulus and response that may control subsequent behavior, cognition, perception, or performance. (From APA Thesaurus of Psychological Index Terms, 8th ed.)
