--7 . 7 -cl...l...clr-l.r r r rrrrrrrn r . . *. r r cr I -r --.--r -, Study Design: Two-group repeated measures design using a sample of convenience of subjects with anterior cruciate ligament (ACL) reconstructive surgery. Objectives: To determine the effect of incorporating one specific weight-bearing exercise (lateral slide exercise using a slide board) into an ACL reconstruction home exercise program. Background: Reduced clinic visits have increased the importance of home exercise programs in knee ligament reconstruction rehabilitation. Few studies have been conducted to test the efficacy of specific exercises as part of a homebased treatment program on subjects who have undergone ACL reconstruction. Methods and Measures: Fourteen subjects who underwent patella tendon autograft reconstruction on one of their ACLs were studied. Testing consisted of the following 4 measurements: peak isometric knee extension torque, peak isometric knee flexion torque, maximum lateral step height, and lateral step-up repetitions to fatigue. Subjects were pretested at 8 weeks after surgery and were randomly placed into either a control or experimental group. The postsurgical rehabilitation was similar for both groups, except the experimental group incorporated lateral slide exercise into their home exercise program. All subjects were reevaluated 14 weeks after surgery. Results: A 2-way repeated measure ANOVA (group by test session), and posthoc testing revealed significant improvements in the slide group for quadricep strength (101.9 2 31.3 N m to 140.5 ? 31.3 N m of torque), while the control group showed no significant increase (125.1 2 61.7 N m to 125.8 + 45.1 N m of torque). Lateral step height also improved in the slide group (from 22.9 + 5.3 cm to 28.7 + 5.6 cm), while the control group showed no increase (20.0 2 4.5 cm to 20.7 2 3.4 cm). Both groups increased in lateral step-up repetitions to fatigue. Conclusion: Including lateral slide exercise in a home exercise program after ACL reconstruction appears to improve knee extension strength. ) Orthop Sports Phys Ther 2000;30:602-61 l .

The effects of proprioceptive or strength training on the neuromuscular function of the ACL reconstructed knee: a randomized clinical trial

“…Based on a hypothesized 10–12% difference in PeakTT between the two groups, the number of participants required to achieve a power of greater than 0.85 was estimated by power analysis. The number of participants used (per group) in this study is comparable to published prospective ACL rehabilitation studies (Ihara & Nakayama, 1986; Blanpied, Carroll, Douglas, Lyons, Macalisang, Pires, 2000; Wojtys, Huston, Taylorm, Bastian, 1996).…”

“…Thus, there is the likelihood that this study was underpowered to demonstrate differences between the two groups in the secondary outcome measures. However, other published ACL rehabilitation studies have used similar number of participants per group (Ihara & Nakayama, 1986; Blanpied et al, 2000; Wojtys et al, 1996). Also, despite the small sample size used, this study revealed a significant interaction effect between the type and the duration of training on neuromuscular function.…”

A Systematic Review of Anterior Cruciate Ligament Reconstruction Rehabilitation –Part II: Open Versus Closed Kinetic Chain Exercises, Neuromuscular Electrical Stimulation, Accelerated Rehabilitation, and Miscellaneous Topics

“…Blanpied et al, 3 in a 2000 study, assessed the effectiveness of adding a slide board home exercise program 2 times per week to a standard physical therapy regimen. Fourteen patients were randomly assigned to 2 groups 8 weeks following ACL reconstruction using a bonepatellar tendon-bone autograft.…”

Changes in Isokinetic Muscle Strength of the Lower Extremity in Recreational Athletes with Anterior Cruciate Ligament Reconstruction

“…After 3 weeks, each subject was instructed to do closed kinetic chain (CKC) exercises such as squats and lateral step-ups with gradual body-weight bearing. [15][16][17] After 4 weeks, bike exercises were commenced. At 3 months postsurgery, most subjects were able to fully extend the knee and commenced walking/running exercises.…”
