The purposes of this meta-analysis/systematic review were to (1) examine the effectiveness of physical therapy exercises following THA and (2) determine whether supervised and home-based exercise regimens are comparable with respect to strength, gait, function, and quality of life. Results indicated that the prescription of exercise following THA resulted in significantly better hip abductor strength, gait speed, and cadence, but not hip flexor, hip extensor, or knee extensor strength. There were no significant differences between supervised or home-based exercise interventions with respect to gait speed, cadence, and functional outcomes, except for the Timed Up and Go Test, which favoured the supervised group.

Fragility Indexは、重要な所見の解釈を助けるツールで、結果の強さの尺度を提供します。Fragility Indexは、その所見が有意でなくなるために、二項対立の結果に追加する必要がある連続した事象の数を表します。数値が小さいほど弱い所見を表し、数値が大きいほど強い所見を表します。
なぜ今この研究が必要なのですか?
As the population ages, the number of patients undergoing total hip arthroplasty (THA) is steadily increasing. Exercise prescription for rehabilitation following a THA is variable, and is based more so on clinical experience, rather than concrete, methodologically-sound evidence. One systematic review examining the effectiveness of physical therapy following THA concluded that, based on studies published in 2004 or earlier, there was insufficient evidence to provide solid recommendations on this topic. Therefore, this systematic review/meta-analysis was needed to summarize more recent research regarding the effectiveness of both physiotherapist-guided rehabilitation exercises and home-based exercises performed independently.
主な研究課題は何ですか?
Are physiotherapist-guided rehabilitation exercises effective in improving strength, gait, function and quality of life in patients who have undergone total hip arthroplasty, and how does this compare to the prescription of home-based exercises performed independently?
重要な知見は?
- 5 randomized trials were included in this review. Three compared an experimental group to a control group, one compared two experimental groups, and one compared two experimental groups with a control group.
- A meta-analysis of 4 studies (n=137) concluded that rehabilitation exercises after discharge significantly improved hip abductor strength (MD: 16 Nm; 95% CI 10 to 22; p<0.05). Separate analyses found no significant effect of post-discharge exercises on hip flexor strength (3 studies; n=111; MD: 6 Nm; 95% CI -2 to 13), hip extensor strength (3 studies; n=111; MD: 21 Nm; 95% CI -2 to 44), or knee extensor strength (2 studies; n=58; MD: 42 Nm; 95% CI -4 to 89) (all p>0.05).
- Post-discharge exercises significantly improved gait speed (2 studies; n=79; MD: 6 m/min; 95% CI 1 to 11) and cadence (1 study; MD: 20 steps/min; 95% CI 8 to 32) (both p<0.05).
- 2 studies assessed function as an outcome; however, the scale on which function was measured varied between these studies. One study, reporting Harris Hip Scores, found exercise to have a significantly beneficial effect on function; however, the mean between-group estimate was only 0.9 points (95% CI 0.2 to 1.6). Significantly better functional outcomes with post-discharge exercises were also observed in the second study (which used the 12-item Hip Questionnaire) (MD in medians 1.5 points; p=0.01).
- One study compared hip abduction strength between home-based exercises and supervised exercises. This study found that the supervised group improved significantly more (by 5.4 Nm); however, differences in baseline measurements may have influenced this result.
- Pooled results from two studies (n=40) revealed no significant differences in gait speed (MD: 8 m/min; 95% CI -9 to 24) or cadence (MD: 2 steps/min; 95% CI -4 to 8) whether the exercise intervention was supervised or home-based (p>0.05).
- One study compared functional outcomes (both objective and patient-reported) between supervised and home-based exercise interventions. This study found no significant difference in patient-reported function (measured on the WOMAC scale), or in the time to ascend four stairs, lower limb power and the 6-minute walk test (all objective measures) (p>0.05). For the Timed Up and Go Test, significantly better results were observed in the supervised group (MD: 1.8 seconds; 95% CI 0.1 to 3.5).
- Results from one study found that quality of life (measured on the Assessment of Quality of Life questionnaire) was similar between exercises that were supervised or home-based (MD: 0.05; 95% CI -0.15 to 0.25).
最も覚えておくべきことは?
Post-discharge rehabilitation exercises following total hip arthroplasty (THA) resulted in significantly better hip abductor strength, gait speed, and cadence, but not hip flexor, hip extensor, or knee extensor strength. Two studies evaluating functional outcomes on two separate scales both revealed significant improvements in function with post-discharge rehabilitation exercises compared to no intervention. There were no significant differences between supervised or home-based exercise interventions with respect to gait speed, cadence, and most functional outcomes (except the Timed Up and Go Test, which favoured the supervised group). The effect of post-discharge exercise on quality of life, as well as the effect of supervised versus home-based exercises on strength and quality of life, remain unknown.
それが私の患者ケアにどのように影響するか?
Results from this meta-analysis and systematic review suggest that post-discharge rehabilitation exercises may improve gait and strength in patients who have undergone a total hip arthroplasty (THA). Additional high-quality studies, examining the effect of post-discharge exercise on quality of life, as well as the effect of supervised versus home-based exercises on strength and quality of life, are needed.
