Objective
To determine the effects of using a continuous passive motion (CPM) device for individuals with poor range of motion (ROM) after a total knee replacement (TKR) admitted for postacute rehabilitation.
ROMの制限が強いTKAに対して、CPMは効果があるのか
Design
Randomized controlled trial.
Setting
Inpatient rehabilitation facility (IRF).
入院患者
Participants
Adults (N=141) after TKR with initial active knee flexion <75° on admission to the IRF.
リハ開始時の最初の自動膝関節屈曲ROMが75°未満のTKA後の患者141名
Intervention
Two randomized groups: group 1 (n=71) received the conventional 3 hours of therapy per day, and group 2 (n=70) received the addition of daily CPM use for 2 hours throughout their length of stay.
グループ1：通常のセラピーを一日3時間
グループ2：入院期間中2時間のCPM使用を追加
Main Outcome Measures
The primary outcome measure was active knee flexion ROM. Secondary outcome measures included active knee extension ROM length of stay, estimate of function using the FIM and Timed Up and Go test, girth measurement, and self-reported Western Ontario and McMaster Universities Osteoarthritis Index scores.
第一アウトカムは自動膝関節屈曲ROM。第2アウトカムは、入院期間中の自動膝関節伸展ROM、FIM、Timed up and Go test,周径、self-reported Western Ontario and McMaster Universities Osteoarthritis Index scores
Results
All subjects significantly improved from admission to discharge in all outcome measures. However, there were no statistically significant differences in any of the discharge outcome measures of the CPM group compared with the non-CPM group.
開始から退院まですべてのアウトカムは優位に改善した。しかし、退院時のアウトカムの違いはグループ間に統計的に優位に認められなかった。
Conclusions
CPM does not provide an additional benefit over the conventional interventions used in an IRF for patient after TKR, specifically in patients with poor initial knee flexion ROM after surgery.
TKA後の入院患者に対して、CPMの付加的な効果は認められなかった、特に膝関節屈曲ROMの制限が強い患者に対しては。
