Loew L et al. – The greatest improvements were found in pain, quality of life, and functional status (grades A, B, or C+). A common limitation inherent to the Evidence–Based Clinical Practice Guidelines (EBCPGs) is the heterogeneity of studies included with regards to the characteristics of the population, the interventions, the comparators, the outcomes, the period of time, and the study design. It is strongly recommended to use the Cochrane Risk of Bias Summary assessment to evaluate the methodologic quality of the studies and to consider avenues for future research on how aerobic walking programs would be beneficial in the management of osteoarthritis (OA) of the hip.Methods
- The literature search found 719 potential records, and 10 full–text articles were included according to the selection criteria.
- The Ottawa Methods Group established the inclusion and exclusion criteria regarding the characteristics of the population, by selecting adults of 40 years old and older who were diagnosed with OA of the knee.
- Two reviewers independently extracted important information from each selected study using standardized data extraction forms, such as the interventions, comparisons, outcomes, time period of the effect measured, and study design.
- The statistical analysis was reported using the Cochrane collaboration methods.
- An improvement of 15% or more relative to a control group contributes to the achievement of a statistically significant and clinically relevant progress.
- A specific grading system for recommendations, created by the Ottawa Panel, used a level system (level I for randomized controlled studies and level II for nonrandomized articles).
- The strength of the evidence of the recommendations was graded using a system with letters: A, B, C+, C, D, D+, or D–.
- Evidence from 7 high–quality studies demonstrated that facility, hospital, and home–based aerobic walking programs with other therapies are effective interventions in the shorter term for the management of patients with OA to improve stiffness, strength, mobility, and endurance.
