Proprioception, Body Balance and Functionality in Individuals With Acl Reconstruction

Abstract

Objective: To evaluate and compare proprioception, body balance and knee functionality of individuals with or without unilateral anterior cruciate ligament (ACL) reconstruction. Methods: Forty individuals were divided in two groups: Experimental group, 20 individuals with ACL reconstruction at six months postoperative, and control group, 20 individuals with no history of lower limb pathologies. In the experimental group, we assessed lower limbs with reconstructed ACL and contralateral limb; in the control group the dominant and the non-dominant lower limbs were assessed. All subjects were submitted to joint position sense test to evaluate proprioception, postural control measure in single-limb, and step up and down (SUD) test for functional assessment. Results: There were no deficits in proprioception and postural control. In the SUD test, a 5% decrease in lift up force was found in reconstructed ACL lower limbs, however, a statistically not significant difference. The impact and step down force during the course of test were 30% greater in anatomic ACL than in control lower limbs. Conclusion: The individuals with ACL reconstruction at six months postoperative did not show changes in proprioception and postural control, but showed motor control changes, influencing knee functionality.

Single-Leg Assessment of Postural Stability After Anterior Cruciate Ligament Injury: a Systematic Review and Meta-Analysis

“…If the included studies did not report means, standard deviations, or F values, the corresponding authors were contacted. In two of three cases, the authors responded [ 18 , 57 ] and the respective study was included, while the remainder [ 21 ] was excluded from this meta-analysis.…”

Mechanism of Activating the Proprioceptive NT-3/TrkC Signalling Pathway by Reverse Intervention for the Anterior Cruciate Ligament–Hamstring Reflex Arc with Electroacupuncture

“…Proprioception of the ACL is closely related to knee joint stability, which is realised through feedback regulation of the central nervous system; however, the key node on the pathway remains unknown [ 27 – 30 ]. Many studies confirmed that when the ACL proprioception function is decreased, the neural feedback regulation pathway is bound to be disordered; therefore, it could have further impact on the proprioception function [ 31 , 32 ].…”

The effect of proprioception training on knee kinematics after anterior cruciate ligament reconstruction

“…Although sensory and motor changes have been described in individuals with ACL lesions, such changes have not been well described in individuals who have undergone ACL reconstruction [2]. After ACL reconstruction, these sensory and motor changes are more variable and, therefore, more difficult to describe [6]. Even though the proprioception can not be measured directly, it affects the knee joint kinematics during high demanding motion tasks such as loading and extreme rotation conditions.…”
