Effectiveness of Tailored Activity Pacing for Symptomatic Osteoarthritis

In the United States, osteoarthritis is a growing public health issue and a leading cause of
disability among older adults. Almost 50% of users of the Veterans Affairs (VA) system
present with osteoarthritis. Veterans are a particularly important group to target for
symptom management interventions as they are twice as likely as non-veterans to report
chronic joint symptoms and activity limitations. There are few evidence-based symptom
management interventions offered by health care professionals, such as occupational and
physical therapists, at the time when people are seeking treatment for their symptoms. The
proposed activity pacing intervention is individually-tailored to a person's symptom and
activity patterns. This tailoring provides a personally-relevant and focused intervention
that may help people adopt this strategy into their daily lives.

Inclusion Criteria:

- Age of 50 years and older

- Reported pain for at least 3 months

- Adequate cognition to complete study activities (score of 5 on the 6-Item Screener)

- Ability to use the Actiwatch-S (Phillips-Respironics, Mini-Mitter, Bend
OR)accelerometer to record symptoms and activity patterns (ascertained by completion
of a learning module specific to the use of the device in this study)

- English-speaking

Exclusion Criteria:

- Self-reported medical history of conditions with pain and/or fatigue as a known and
marked symptom (e.g multiple sclerosis, rheumatoid arthritis)

- Medically unstable (e.g. acute conditions or acute presentations of chronic
conditions)

ability to complete study procedures

- Current enrollee in physical or occupational therapy for symptoms associated with
osteoarthritis

- Current attendance or attendance within the previous year in a cognitive behavioral
therapy program or other self-management program that includes activity pacing
instruction

- Any other unforeseen exclusion criteria that, by the opinion of the study personnel,
would make the participant unable to safely or effectively complete the study.
