To determine IFMs size and quality using US imaging following rehabilitation in patients with CAI.
Prospective cohort study.
University Laboratory.
26 patients with CAI (age:21.9 ± 3.5 yrs; 18F, 8M) completed 8 clinician-supervised rehabilitation sessions over a 4-week period.
US imaging assessed IFM cross-sectional area (CSA) in seated and standing positions for both trained and untrained legs before and after the intervention. Muscle quality was evaluated using grey scale analysis for echogenicity.
Significant (P < 0.01) increases in normalized CSA were observed for AbH and FDB in both seated and standing positions. Significant improvements (P < 0.05) were also seen in the untrained leg during standing. No significant changes were found in seated positions or in echogenicity for AbH (P = 0.26) and FDB (P = 0.052) for the trained leg.
IFM CSA increased post-rehabilitation, with some cross-over effects in the untrained leg. There was a certain cross-over effect observed. The muscle quality measures didn't change for the IFMs before and after rehabilitation. The IFMs strengthening should be included in CAI rehabilitation programs. There is a definite increase in size after rehabilitation. However, for quality changes there may be a need of longer rehabilitation programs.
采用超声成像确定慢性踝关节不稳（CAI）患者康复后的距下关节内翻肌（IFM）大小和质量。
前瞻性队列研究。
大学实验室。
26例CAI患者（年龄：21.9±3.5岁；18名女性，8名男性）在4周内完成了8次由临床医生监督的康复训练。
干预前后，通过超声成像评估训练腿和未训练腿在坐位和站立位时IFM的横截面积（CSA）。使用灰度分析回声性评估肌肉质量。
在坐位和站立位时，AbH和FDB的标准化CSA均显著增加（P<0.01）。站立时，未训练腿也有显著改善（P<0.05）。训练腿在坐位时以及AbH（P=0.26）和FDB（P=0.052）的回声性方面未发现显著变化。
康复后IFM的CSA增加，未训练腿有一定的交叉效应。观察到了一定的交叉效应。康复前后IFM的肌肉质量指标没有变化。CAI康复计划应包括IFM强化训练。康复后大小有明显增加。然而，对于质量变化，可能需要更长的康复计划。
