“…The types of surgery for ACL reconstruction were as follows: (a) graft from the hamstring muscles [29,[45][46][47]; (b) graft from the patellar tendons [43]; (c) mixed type using grafts from hamstrings and patellar tendons [33,48,49]; and (d) mixed type using grafts from hamstrings, patellar tendons, and allografts [35,[50][51][52]. Four studies [44,[53][54][55] did not report complete information about the type of graft used for the ACL reconstruction.…”

“…Physical Activity Level. Physical activity of the participants with ACL injury at the time of brain activity measurements was assessed by the Tegner scale in 11 studies, ranging from 4.5 (representing a moderately heavy labor) [47] to 7.3 (representing participating in competitive sports) [53]. The Baecke questionnaire was used in one study [23] with an average score of 7.8 ± 1.4; two studies [34,57] only provided a range of weekly hours (i.e., 1-7 h per week) of physical activity; two studies [33,52] only provided the preinjury physical activity level; and eight studies [41-43, 45, 46, 56, 58, 59] provided no information about the participants' physical activity level.…”

“…The International Knee Documentation Committee questionnaire was the most commonly used assessment of knee function. Scores of knee function ranged from 77.2 out of 100 [33] to 88.8 out of 100 [53]. Other measures of knee function included the following: the Lysholm Knee Scoring scale (range = 81:7 ± 13:1 [56] to 86:5 ± 3:9 out of 100 [29]); clinical tests such as the Lachman test, Pivot shift, or the Anterior Drawer tests [42,43]; and sensation of giving way [34,57].…”

“…A specific description of the ACL injury and the presence of concomitant injuries can be found in 16 studies. Five studies [34,48,50,51,57] included people with meniscal injuries in addition to the ACL injury; four studies [44,52,54,55] only included people without multiple ligament tears; four studies [29,42,43,47] specifically mentioned to have excluded people with cartilage or meniscal injuries; three studies [53,56,59] reported to only have included people with isolated ACL injury.…”

Anterior cruciate ligament (ACL) injury is a common problem with consequences ranging from chronic joint instability to early development of osteoarthritis. Recent studies suggest that changes in brain activity (i.e., functional neuroplasticity) may be related to ACL injury. The purpose of this article is to summarize the available evidence of functional brain plasticity after an ACL injury. A scoping review was conducted following the guidelines of the Joanna Briggs Institute and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The terms “brain,” “activity,” “neuroplasticity,” “ACL,” “injury,” and “reconstruction” were used in an electronic search of articles in PubMed, PEDro, CINAHL, and SPORTDiscus databases. Eligible studies included the following criteria: (a) population with ACL injury, (b) a measure of brain activity, and (c) a comparison to the ACL-injured limb (contralateral leg or healthy controls). The search yielded 184 articles from which 24 were included in this review. The effect size of differences in brain activity ranged from small (0.05, ACL-injured vs. noninjured limbs) to large (4.07, ACL-injured vs. healthy control). Moreover, heterogeneity was observed in the methods used to measure brain activity and in the characteristics of the participants included. In conclusion, the evidence summarized in this scoping review supports the notion of functional neuroplastic changes in people with ACL injury. The techniques used to measure brain activity and the presence of possible confounders, as identified and reported in this review, should be considered in future research to increase the level of evidence for functional neuroplasticity following ACL injury.

“…Therefore, muscle weakness may be an important etiological factor in PF. To date, however, no study has yet investigated the proximal muscles such as the hamstring and quadriceps muscles in terms of strength and reaction time in patients with PF, though these muscles play a role in the alteration of lower extremity biomechanics [12][13][14][15] and may contribute to increased plantar fascia load.…”

Background: Muscle weakness has been reported to be an important etiological factor in plantar fasciitis (PF), but the data available in the quadriceps, hamstring, gastrocnemius (GCM) muscles is limited . The aim of the study was to compare the strength and reaction time of the quadriceps, hamstring, and gastrocnemius (GCM) muscles and foot pressure between patients with PF and normal controls. Methods: 21 PF patients and 21 normal controls were registered. Muscle strength was measured by the peak torque per body weight (Nm kg−1 × 100). Muscle reaction time was evaluated by the acceleration time (AT, milliseconds). Foot pressure and posture were assessed by pedobarography [valgus/varus index (VV index), %].Results: The strength of the quadriceps was significantly decreased in the affected ankles of the PF group than in the control group (p=0.005). The AT of the quadriceps and hamstring muscles was significantly increased in the affected ankles of the PF group than in the control group (quadriceps: p=0.012, hamstring: p=0.001), while the AT of the GCM muscle was significantly decreased (p=0.009) and was significantly negatively correlated with quadriceps muscle strength (r=-.598, p = .004) and AT (r=-.472, p=.031). Forefoot (p=0.001) and hindfoot (p=0.000) pressure were significantly greater, with the VV index showing hindfoot valgus, in the affected ankles of the PF group when compared to those of the control group (p=0.039).Conclusion: This study demonstrated weakness and delayed reaction time of the quadriceps and hamstring muscles, with a rapid reaction time of the GCM muscle, in PF patients. Clinical Relevance: Clinicians and therapists should assess the function of the quadriceps and hamstring muscles when planning the management of PF patients without muscle tightness.

Hamstrings vibration reduces tibiofemoral compressive force following anterior cruciate ligament reconstruction

Individuals who have undergone anterior cruciate ligament reconstruction (ACLR) are at greater risk of developing knee osteoarthritis (OA). This elevated risk of knee OA is associated with high tibiofemoral compressive force, due to a combination of low knee flexion angles and increased co‐contraction of the hamstrings and quadriceps during limb loading. Prolonged vibration of the hamstrings fatigues the intrafusal muscle fibers, which reduces autonomic reflexive excitation of the hamstrings and alleviates reciprocal inhibition to the quadriceps. The aim of this study was to examine the effect of prolonged hamstrings vibration on tibiofemoral compressive force in individuals who have undergone ACL reconstruction. Fourteen participants with unilateral ACLR and 14 participants without knee injury performed a single‐leg drop‐land task before and after prolonged (20 min) vibration of the hamstrings. Peak tibiofemoral compressive force, knee flexion angle, and hamstrings/quadriceps co‐contraction were calculated during the deceleration phase of the drop‐land task before and after vibration. The ACLR group experienced an 18% decrease in tibiofemoral compressive force, a 32% increase in knee flexion angle, and a 38% decrease in hamstrings/quadriceps co‐contraction after hamstrings vibration. There was no difference in any of the parameters in the non‐injured group after vibration. These data suggest that acute prolonged hamstrings vibration has the potential to mitigate tibiofemoral compressive force, which may protect the knee joint in the long‐term.This article is protected by copyright.

Quadriceps Neuromuscular Function and Jump-Landing Sagittal-Plane Knee Biomechanics After Anterior Cruciate Ligament Reconstruction

Abstract: Greater quadriceps MVIC and CAR may provide better energy attenuation during a jump-landing task. Individuals with greater peak vGRF in the ACLR limb possibly require greater spinal-reflex excitability to attenuate greater loading during dynamic movements.
