“…11 This isokinetic variable has been correlated with the nerve conduction velocity. 7 Because it is well established that the isokinetic muscle characteristics for any given sport reflect specific features and demands of the sport practice, [11][12][13][14][15] analysis of the variable "acceleration time" in running and triathlon athletes is essential in order to draw up further strategies for injury prevention programs. Moreover, there is a scarcity of data on this variable in isokinetic ankle tests, and such tests need to be reproducible for better sports practice.…”

“…5 The muscle reaction mechanism is related to the arthrokinetic reflex, 6 which is influenced by velocity and acceleration; these, in turn, are important parameters in relation to motor function but have been less investigated than muscle strength and resistance. 7 The phenomenon of acceleration has been investigated through methodologies such as trapdoor experiments and electromyography. [8][9][10] However, isokinetic analysis is an assessment method that is more dynamic 11 and shows a behavior that is closer to the functionality of the sport.…”

INTRODUCTION:Adequate muscle reaction time is essential for protecting the joints against injuries during sports activities. This phenomenon of time of acceleration has been investigated through methodologies such as trapdoor experiments and electromyography. However, isokinetic analysis is an assessment method that is more dynamic and shows behavior closer to the functionality of the sport. Sports that involve running, such as long distance running and triathlon, have high lower-limb injury rates, particularly in relation to the ankle joint. The objective of this study was to evaluate and compare isokinetic acceleration and deceleration times of the dorsiflexor and plantar flexor musculature of the ankle in long-distance runners, triathletes and non-athletic individuals. METHOD: The sample comprised 75 individuals (men aged 18-42 years), divided into three groups: triathlete group, long-distance runner group and control group. The individuals were tested bilaterally on an isokinetic dynamometer. The evaluation modes used were (i) concentric/eccentric for plantar flexion and dorsiflexion, and (ii) eccentric/concentric for plantar flexion and dorsiflexion. We used (a) analysis of variance and Tukey's post hoc test; (b) Kruskal-Wallis and Müller-Dunn post hoc tsts; (c) Chi-square tests. RESULTS:The acceleration time during concentric contraction was statistically different only between the control group and the long-distance runner group, such that the controls presented faster acceleraton. CONCLUSION: This may signify a deficiency in their motor sensory control during concentric activity of the dorsiflexors.

PurposeTo compare functional outcomes such as muscle strength, neuromuscular control and patient‐reported outcomes (PROs) between patients with healed rotator cuffs and those with retears after arthroscopic rotator cuff repair (RCR).MethodsOne hundred and nine patients who underwent arthroscopic RCR were included (85 in the healed group, 24 in the retear group). Shoulder muscle strength and neuromuscular control index (acceleration time [AT]) were evaluated using an isokinetic device. PROs were assessed using the pain visual analogue scale (VAS), Simple Shoulder Test (SST), American Shoulder and Elbow Surgeons (ASES) and University of California at Los Angeles (UCLA) scores. Continuous variables were compared using independent t tests. Multiple linear regression analysis was used to identify the influence of the predictor variables on the dependent variable.ResultsThe muscle strength and ATs for external rotators (ERs), internal rotators (IRs) and forward flexors as well as PROs including VAS, SST and ASES scores, were not significantly different between the two groups pre‐ and postoperatively (n.s.). Multiple linear regression analysis revealed that postoperative ATs for the IRs (p = 0.006) and ERs (p = 0.028) in the operated shoulders were closely associated with the postoperative UCLA score.ConclusionsCompared with the healed group after arthroscopic RCR, the retear group had no clinically relevant differences in muscle strength, ATs and PROs, including VAS, SST, ASES and UCLA scores. However, postoperative ATs for IRs and ERs in the operated shoulders were a significant predictor of postoperative UCLA scores. Therefore, clinicians and therapists need to be aware of the importance of neuromuscular control in patients who have undergone arthroscopic RCR and prioritize therapeutic exercises to restore neuromuscular control.Level of EvidenceLevel III.

Purpose To compare proprioception, postural stability, and neuromuscular control between patients with mechanical laxity and recurrent ankle sprain. Methods Among 86 patients with ankle instability, 45 patients had mechanical laxity (mean age 27.2 ± 7.0 years) and 41 had recurrent ankle sprain (mean age 25.1 ± 9.2 years). Both the affected and unaffected ankles of each patient were evaluated. Proprioception and neuromuscular control tests were conducted using an isokinetic machine, and postural stability was tested using a postural stabilometry system. Results Proprioception was not significantly different between the unaffected or affected ankles of the mechanical laxity group compared with those of the recurrent ankle sprain group (n.s). Static and dynamic postural stability and neuromuscular control were similar in the affected ankles between the two groups (n.s). However, postural stability (static, overall: p = 0.009, anterior–posterior: p = 0.028, medial–lateral: p = 0.022; dynamic, overall: p = 0.012, anterior–posterior: p = 0.004, medial–lateral: p = 0.001) and neuromuscular control (inversion: p = 0.031, eversion: p = 0.039, dorsiflexion: p = 0.029, plantarflexion: p = 0.035) were significantly decreased in the unaffected ankles of the recurrent ankle sprain group compared with those of the mechanical laxity group. Conclusion The unaffected ankles of the recurrent ankle sprain group showed significant decreases in both postural stability and neuromuscular control compared with the mechanical laxity group. Clinicians and therapists should consider unaffected ankle rehabilitation in patients with recurrent ankle sprain to prevent future sprain events. Level of evidence Case–control study, III.
