Whole Body Vibration Enhances Recovery After ACL Reconstruction
Whole Body Vibration Expedites and Improves Recovery of Anterior Cruciate Ligament (ACL) Rupture and Subsequent Arthroscopic Reconstructive Surgery.
- The whole body vibration group experienced no muscle atrophy or weakness after surgery, while the control group suffered femoral muscular atrophy, weakness and decreased coordination.
- Twelve weeks after surgery, the whole body vibration group was more satisfied with the results of the surgery; participants were stronger and felt better.
- The whole body vibration group reported less pain than the control group.
- Research suggests that Power Plate® training is significant resource for patients wishing to enhance recovery and regain strength in order to return to daily activities or work and sport
Weakness and atrophy in the muscles of the quadriceps group is a common challenge for patients recovering from reconstruction of the anterior cruciate ligament. The aim of this study was to examine the effects of Power Plate training on the healing process. This study sought to build upon previously published research outcomes and investigate the hypothesis that Power Plate training leads to increased co-activation of the extensor and flexor muscles of the lower extremities, causing positive effects on joint stabilization, strength and circulation.
Sixteen subjects were divided among two groups. Any contraindications to vibration training were considered. The whole body vibration group used Power Plate combined with conventional physiotherapy. The control group only used conventional physiotherapy. The conventional physiotherapy included the performance of squats and lunges, 2-3 times per week.
The whole body vibration group performed a 10-minute whole body vibration program two times per week for ten weeks, beginning the third week after surgery, in addition to performing conventional physiotherapy. They used Power Plate to warm up with massage exercises for the quadriceps and hamstrings, they then performed squats and lunges, followed by hamstring stretches.
Measurements of leg circumference (10 cm and 20 cm above the knee, 15 cm below the knee) were taken before surgery, and again after surgery at six and 12 weeks (see fig. 2). The objective findings of muscle measurements were supplemented by subjective data evaluating pain perception and wellbeing using a questionnaire.
The whole body vibration group maintained size and strength of leg musculature while the control group suffered atrophy and loss of strength. (see fig. 1).
Fig. 2 demonstrates maintenance of muscular size and strength for the whole body vibration group. The control group participants experienced average muscle atrophy in the quadriceps group, and were not able to regain pre-operative strength in all muscle groups 12 weeks after surgery. The whole body vibration group experienced no atrophy and no strength loss.
Several questions were asked before and after the surgery and the rehabilitation program about pain reduction and improvement of general well-being (see fig. 3). The answers clearly indicated that the whole body vibration group experienced less pain and improved at a faster rate than the control group.
Recovery from a rupture of the ACL generally leads to atrophy of the thigh and calf muscles as well as dysfunction of the knee in terms of coordination, mobility and stability. Power Plate® training leads to an increase in muscle girth, retention of strength, recovery of coordination, mobility and flexibility. This evidence suggests that whole body vibration therapy, performed on Power Plate, following surgery aids in stabilizing joints and preventing further trauma. It provides a significant resource for patients wishing to recover rapidly from ACL or joint surgery in order to return quickly to life activities, work and sport.
