Effects of cognitive task demands on subsequent symptoms and activity in adults with symptomatic osteoarthritis.

Objective: Adults with osteoarthritis (OA) experience fatigue in daily life that is negatively related to physical activity; however, it is unclear how task demands affect fatigue and occupational performance. We examined effects of a cognitive task on subsequent symptoms and activity.

Method: Adults with knee or hip OA completed a standardized cognitive task during a lab visit.

Effect of tailored activity pacing on self-perceived joint stiffness in adults with knee or hip osteoarthritis.

Objective: We examined the effects of a tailored activity-pacing intervention on self-perceived joint stiffness in adults with osteoarthritis (OA).

Method: Thirty-two adults with hip or knee OA were randomized to a tailored or general activity-pacing intervention. Participants' symptoms and physical activity over 5 days were used to tailor activity pacing.

Fatigability in osteoarthritis: effects of an activity bout on subsequent symptoms and activity.

Background: Older adults with osteoarthritis (OA) are more likely to experience increased fatigue following bouts of physical activity than those without OA. The highly "fatigable" nature of this population is problematic as it has been linked to OA severity and decreased function. This study examined the effects of engaging in standardized lab-based physical tasks on subsequent fatigue, pain, and activity in older adults with OA.

Randomized controlled trial comparing tailoring methods of multimedia-based fall prevention education for community-dwelling older adults.

Objective: We attempted to determine whether multimedia fall prevention education using different instructional strategies increases older adults' knowledge of fall threats and their fall prevention behaviors.

Method: Fifty-three community-dwelling older adults were randomized to iwo educational groups or a control group. Multimedia-based educational interventions to increase fall threats knowledge and encourage fall prevention behaviors had two tailoring strategies: (1) improve content realism for individual learners (authenticity group) and (2) highlight program goals and benefits while using participants' content selections (motivation group).

Deficits in stepping response time are associated with impairments in balance and mobility in people with Huntington disease.

Huntington disease (HD) is a disorder characterized by chorea, dystonia, bradykinesia, cognitive decline and psychiatric comorbidities. Balance and gait impairments, as well as falls, are common manifestations of the disease. The importance of compensatory rapid stepping to maintain equilibrium in older adults is established, yet little is known of the role of stepping response times (SRTs) in balance control in people with HD.

Changes in hemiplegic grasp following distributed repetitive intervention: a case series.

The purpose of this pilot study was to investigate the efficacy of a distributed model of repetitive and focused intervention on grasp force, and clinical and functional hand measures in persons with chronic hemiplegia and limited hand recovery from self-reported stroke. A case series design was used. Focused repetitive unilateral and bilateral interventions were provided in a distributed manner (three times a week for 6 weeks) to three persons with upper limb hemiplegia of more than 1 year.
