Intensity of exercise for the treatment of osteoarthritis

 

Abstract

Background

Therapeutic exercise is used as one modality to treat people with osteoarthritis (OA).

Objectives

To evaluate the effectiveness of therapeutic exercise of differing intensities on objective and subjective measures of disease activity in people with OA.

Search methods

We searched MEDLINE, EMBASE, Pedro, Current Contents, Sports Discus and CINAHL up to and including December 2002. The Cochrane Field of Rehabilitation and Related Therapies and the Cochrane Musculoskeletal Review Group were also contacted for a search of their specialized registers. Handsearching was conducted on all retrieved articles for additional studies.

Selection criteria

Comparative controlled studies, such as randomized controlled trials, controlled clinical trials, cohort studies or case/control studies, of therapeutic exercises compared to control or active interventions in people with OA were eligible. No language restrictions were applied. Abstracts were also accepted.

Data collection and analysis

Two independent reviewers identified potential articles from the literature search. These reviewers extracted data using pre-defined extraction forms. Consensus was reached on all data extraction. The two reviewers used a five point scale to assess the quality of the selected articles. Randomization, double-blinding and description of withdrawals were assessed.

Main results

One study involving 39 participants met the inclusion criteria. The review indicates that there were no significant differences between high intensity and low intensity aerobic exercise on participants with OA of the knee for functional status, gait, pain and aerobic capacity (Mangione 1999).

Authors' conclusions

Both high intensity and low intensity aerobic exercise appear to be equally effective in improving a patient`s functional status, gait, pain and aerobic capacity for people with OA of the knee. Further research involving a greater number of subjects, and a larger number of studies involving a control group is needed to further substantiate these results.

 

Plain language summary

Intensity of exercise for osteoarthritis

Either high intensity or low intensity aerobic exercise improves functional status, pain, gait, and aerobic capacity in people with osteoarthritis of the knee

Therapeutic exercise has been recommended as part of a treatment regime for people with osteoarthritis to improve functional status and decrease disability and pain. It is thought that aquatic, functional, or aerobic exercise has this potential. Attention has been centred on the level of intensity of exercise to determine whether low intensity or high intensity exercise is more efficacious. High intensity exercise involves exercising at a higher target heart rate as compared with low intensity exercise. One study, with 39 participants,was identified for this review. Both levels of exercise were beneficial. There were no statistically or clinically significant differences between high intensity and low intensity aerobic exercises in people with osteoarthritis of the knee for measures of functional status, pain, gait, and aerobic capacity.

 

摘要

背景

運動強度於治療退化性膝關節炎

治療性運動為治療退化性膝關節炎方法之一。

目標

研究不同運動強度治療退化性膝關節炎的效果。

搜尋策略

搜尋MEDLINE, EMBASE, Pedro, Current Contents, Sports Discus and CINAHL (直到2002年12月)。同時手動搜尋文章之參考文獻。

選擇標準

比較運動治療退化性膝關節炎與安慰劑，或另一種治療之所有隨機對照試驗及控制對照研究、世代研究、病例對照研究。

資料收集與分析

兩位作者使用預定條件獨立進行資料摘錄，並對每篇試驗研究的品質進行評估。

主要結論

1個研究包含39位病患於分析中。研究顯示 高強度或低強度有氧運動治療退化性膝關節炎在功能狀態、步態及有氧運動能力，並無顯著差異。

作者結論

高強度與低強度有氧運動治療退化性膝關節炎在功能狀態、步態及有氧運動能力，並無顯著差異。未來需更多病人數及控制組研究以使結果更強化。

總結

無論是高強度，低強度的有氧運動都可改善膝關節退化性關節炎病患功能狀態，疼痛，步態，有氧能力。治療性運動已經被建議作為治療退化性關節炎的一部分，因為可以改善功能狀態，減少傷殘和痛苦。水中，功能性，或有氧運動被認為有這個潛能。注意力被集中在運動強度的等級，以確定是否低強度或高強度的運動更有效。比起低強度運動，高強度的運動涉及更高的心律目標。一項研究，有39人被確定在這一文獻回顧。兩個強度的運動都是有益的。高強度與低強度的有氧運動用於膝蓋退化性關節炎的功能狀態測量，疼痛，步態，與有氧能力，在統計學或臨床沒有顯著差異。
