CONCLUSIONS Utilizing a consumer-based wearable activity tracker as either the primary component of an intervention or as part of a broader physical activity intervention has the potential to increase physical activity participation .
BACKGROUND The range of benefits associated with regular physical activity participation is irrefutable .
Despite the well-known benefits , physical inactivity remains one of the major contributing factors to ill-health throughout industrialized countries .
Traditional lifestyle interventions such as group education or telephone counseling are effective at increasing physical activity participation ; however , physical activity levels tend to decline over time .
Consumer-based wearable activity trackers that allow users to objective ly monitor activity levels are now widely available and may offer an alternative method for assisting individuals to remain physically active .

Feasibility and preliminary efficacy of a physical activity counseling intervention using Fitbit in people with knee osteoarthritis: the TRACK-OA study protocol
Background Physical activity ( PA ) reduces pain and improves functioning in people with knee osteoarthritis ( OA ) , but few people with the condition meet recommended PA guidelines . Successful intervention strategies to increase PA include goal setting , action planning , self-monitoring , and follow-up feedback from a healthcare professional . Recently developed consumer wearable activity trackers allow users to set activity goals , self-monitor daily goal -progress , and provide feedback on goal attainment . It is hypothesized that a multi-component physiotherapist-led intervention that includes a short ( 40-min ) education module , guided goal - setting and action planning , the use of a wristb and activity tracker , and weekly follow-up phone calls will lead to increased PA outcomes . Methods / design Thirty-six participants will be recruited from the community for a two-group pilot r and omized controlled trial with a stepped-wedge design using an intention-to-treat analysis . Computer-generated block r and omization will be performed using varying block sizes and a 1:1 allocation ratio . The 4-week intervention will be delivered immediately ( immediate-intervention group ) or after a 5-week delay ( delayed-intervention group ) . Outcome measures of pain and disability ( Knee Injury and OA Outcome Score ) , disease self-management ability ( Partners in Health Scale ) , and objective bouted moderate-to-vigorous PA and sedentary time ( BodyMedia SenseWear Mini Armb and ) will be collected at baseline ( week 0 ) and two follow-ups ( weeks 5 and 10 ) , for a total study duration of 11 weeks . Feasibility data relating to process , re source , management , and scientific elements of the trial will be collected . Outcome measure and feasibility data will be summarized , and an estimate of intervention efficacy will be obtained by regression model with planned comparisons . The trial began recruiting in February 2015 . To date , 34 subjects have been recruited . Discussion This study will evaluate the feasibility and preliminary efficacy of a novel intervention to promote  PA in people living with knee OA . The results will provide valuable information to inform a larger r and omized trial to assess intervention effectiveness . Trial registration Clinical Trials.gov Identifier : NCT02313506 ( registration date 8 December 2014 ) . First participant r and omized 20 February 2015
