Evaluation of Single-Leg Standing Following Anterior Cruciate Ligament Surgery and Rehabilitation

Abstract

The findings suggest that single-leg standing balance can be reliably evaluated by physical therapists. The single-leg standing balance test, however, may not provide information that assists clinicians in determining clinical change or functional level for patients following rehabilitation for ACL surgery.

Análise comparativa do controle postural de indivíduos com e sem lesão do ligamento cruzado anterior do joelho

“…Many methods have been used to evaluate postural control aiming to quantify this disorder for enabling a better follow-up on the evolution of surgical or conservative treatment of patients with this kind of injury. Strength platform and its adjustments are the instruments most frequently used to measure balance of individuals with ACL injury or submitted to any kind of treatment (8,10,17,18,19) . No papers describing the use of pressure sensors for that purpose, such as the F-SCAN MATT, were found.…”

“…Proprioceptive neurophysiologic function of the ACL has been considered as important as its biomechanical role in maintaining joint stability (7). Complications that occurred after ACL injury, such as osteoarthrosis, seem to happen not only due to mechanical instability, but also to the reduction or change of the proprioceptive information (5,8) . Many theories suggest that the ACL receptors and other knee structures' receptors play a fundamental role on maintaining the dynamic stability of this joint, based on existent reflex paths between the knee and thigh musculature (4) .…”

“…During static posture, the key measure used to calculate balance is PC oscillation, although there is no consensus regarding its importance on ACL injuries. The most frequently used equipment for measuring PC in many pathologies, which can be found in literature, are the strength platform (12,13,14,15) or an equipment similar to extensometric platforms (8,16,17,18) . However, there are other equipment able to measure PC, such as pressure sensors.…”

Concurrent Validity by Comparing EMG Activity between Manual Muscle Testing, Handheld Dynamometer, and Stationary Dynamometer in Testing of Maximal Isometric Quadriceps Contraction

“…Each subject cycled for 3 minutes to warm up before testing 4) . The dominant leg was determined by performing a simple ball kick test 31,32) , in which subjects were asked, "Which foot would you use to kick a ball?". Subjects were seated on the Biodex chair, and their trunk and pelvis were fixed using pelvic and chest belts.…”

Recent advances following anterior cruciate ligament reconstruction: rehabilitation perspectives

“…Increased progression of single limb balance can include balance with eyes closed, progressing to the entire balance sequence being done on a labile surface. Although these types of exercises are thought to be beneficial for increasing balance and proprioception, their use for objective assessment may be difficult to assess by a clinician as they may not be sensitive enough to determine deficits following ACL reconstruction [91].…”
