decreased muscular strength and alterations in joint biomechanics. Chronic OA pain may lead to
anxiety, depression, fear of movement, and poor psychological outlook. The fear of movement
may prevent participation in exercise and social events which could lead to further physical and
social isolation. Resistance exercise (RX) has been shown to be an effective intervention both for
decreasing pain and for improving physical function and self-efficacy. RX may restore muscle
strength and joint mechanics while improving physical function. RX may also normalize muscle
firing patterns and joint biomechanics leading to reductions in joint pain and cartilage degradation.
These physical adaptations could lead to improved self-efficacy and decreased anxiety and
depression. RX can be prescribed and performed by patients across the OA severity spectrum.
When designing and implementing an RX program for a patient with knee OA, it is important to
consider both the degree of OA severity as well as the level of pain. RX, either in the home or at a
fitness facility, is an important component of a comprehensive regimen designed to offset the
physical and psychological limitations associated with knee OA. Unique considerations for this
population include: 1) monitoring pain during and after exercise, 2) providing days of rest when
disease flares occur, and 3) infusing variety into the exercise regimen to encourage adherence.更多精彩文章及讨论，请光临枫下论坛 rolia.net

Objective: To identify effective strengthening exercise programs and provide rehabilitation teams and
patients with updated, high-quality recommendations concerning traditional land-based exercises for knee
osteoarthritis.
Methods: A systematic search and adapted selection criteria included comparative controlled trials
with strengthening exercise programs for patients with knee osteoarthritis. A panel of experts reached
consensus on the recommendations using a Delphi survey. A hierarchical alphabetical grading system
(A, B, C+, C, D, D+ or D-) was based on statistical significance (p < 0.5) and clinical importance (⩾15%
improvement).
Results: The 26 high-quality studies identified demonstrated that various strengthening exercise
programs with/without other types of therapeutic exercises are generally effective for improving knee
osteoarthritis management within a six-month period. Strengthening exercise programs demonstrated a
significant improvement for pain relief (four Grade A, ten Grade B, two Grade C+), physical function (four
Grade A, eight Grade B) and quality of life (three Grade B). Strengthening in combination with other types
of exercises (coordination, balance, functional) showed a significant improvement in pain relief (three
Grade A, 11 Grade B, eight Grade C+), physical function (two Grade A, four Grade B, three Grade C+)
and quality of life (one Grade A, one Grade C+).
Conclusion: There are a variety of choices for strengthening exercise programs with positive
recommendations for healthcare professionals and knee osteoarthritis patients. There is a need to
develop combined behavioral and muscle-strengthening strategies to improve long-term maintenance of
regular strengthening exercise programs.更多精彩文章及讨论，请光临枫下论坛 rolia.net
