Description of intervention(s) / exposure
18-week, unsupervised home-based progressive walking program performed at the convenience of paticipants schedule.
18-week oral glucosamine sulphate supplementaion (1500 mg daily).
Participants were recruited from the Greater Brisbane area through flyers, television, radio, surveys and various seniors' events.

Feasibility trial.
No control group.
Two treatment groups:

Group 1: 18-week walking program, 3 days per week, starting with 1500 steps in the first week and finishing with 6000 steps by week 18, and 18-week oral glucosamine sulphate supplementation (1500 mg daily)

Group 2: 18-week walking program, 5 days per week, starting with 1500 steps in the first week and finishing with 6000 steps by week 18, and 18-week oral glucosamine sulphate supplementation (1500 mg daily)

Summary
Brief summary
The primary purpose is to evaluate the effectiveness of a walking program, especially the ‘dose’ of walking necessary to elicit clinically significant improvements in well-being among individuals aged 40 to 75 years with early osteoarthritis (OA) and test whether walking combined with glucosamine offers improvements. Improvements in well-being are defined as reductions in pain, stiffness, depression and anxiety and increases in functional ability, and self-efficacy towards exercise.
