“…Despite the improvements in SLCMJs, which may be indicative of increased strength of ankle-and hip-joint muscles, and both static and dynamic postural balance 5 , we cannot claim any prevention effect of the training program imposed. The previous examined chronic ankle instability (CAI) sample displayed an mean RSI value of 0.41, being lower than that displayed by those subjects without CAI (RSI = 0.50) 18 . Despite the SLRJ performance enhancement after the intervention period, both groups revealed a detrimental variation of the ability to change quickly from eccentric to concentric muscular contractions (Standard RSI = 0.28-0.29; Variable RSI = 0.34).…”

“…Subjects stood on one leg on top of a 30-cm high box with hands placed on the hips. Then, hopped down diagonally (45º anterolateral), landed on the same leg within infrared optical system (OptoJump Next-Microgate, Bolzano, Italy), and then jumped vertically as high as possible with the shortest contact time as possible 18 . The reactive strength index (RSI) was automatically calculated using Optojump Next software, version 1.12.1.0 (Microgate, Bolzano, Italy), through the following formula: jump height /contact time 18 .…”

“…Then, they dropped down, landed on both legs, and jumped vertically as high as possible with the shortest ground contact time possible. In unilateral rebound jumps (SLRJ), they hopped down diagonally (45° anterolateral), landed on the same leg within the infrared optical system, and then jumped vertically as high as possible with the shortest contact time possible [ 38 ]. The reactive strength index (RSI) was automatically calculated using Optojump Next software, version 1.12.1.0, through the following formula: jump height/contact time [ 38 ].…”

This pilot study aimed to determine the effects of differential learning in sprint running with and without changes of direction (COD) on physical performance parameters in female basketball players and to determine the feasibility of the training protocol. Nine female basketball players completed 4 weeks of repeated sprint training (RST) with (COD, n = 4) or without (NCOD, n = 5) changes of direction. A battery of sprints (0–10 and 0–25 m), vertical jumps (counter movement jump (CMJ), drop jump, and single-leg CMJs), and COD tests were conducted before and after intervention. NCOD completed two sets of ten sprints of 20 m, whereas COD performed 20 m sprints with a 180 degree turn at 10 m, returning to the starting line. Before each sprint, participants were instructed to provide different fluctuations (i.e., differential learning) in terms of varying the sprint. Both groups had 30 s of passive recovery between two sprints and 3 min between sets. A significant effect of time for the 0–10 m sprint, CMJ, and single leg-CMJ asymmetries were observed. Adding “erroneous” fluctuation during RST seems to be a suitable and feasible strategy for coaches to enhance physical performance in young female basketball players. However, further studies including larger samples and controlled designs are recommended to strengthen present findings.

“…468 Attempts to identify the sensorimotor ROM deficits in those with CAI have received considerable attention. While findings may be dependent on measurement technique and subject selection, investigators have generally identified the following sensorimotor ROM deficits at the foot, ankle, knee, and hip: (1) abnormal timing of muscle activation at the ankle, knee, and hip, 5,86,88,122,131,188,205,211,221,241,242,256,264,269,275,319,330,331,383,399,401,403,406,407,430,442,459,460 (2) decreased force output/strength at the ankle 3,59,60,138,235,249,333,343,352,473,481 and hip, 87,249,301,305,333 (3) impaired force and proprioception at the ankle, 22,59,…”

Similar findings were noted by others.…”

B Clinicians should include patient age, body mass index, pain coping strategies, report of instability, history of previous sprain, ability to bear weight, pain with weight bearing, ankle dorsiflexion range of motion (ROM), medial jointline tenderness, balance, and ability to jump and land (as safely tolerated) in their initial assessment, because of their role in influencing the clinical course and estimation of time to accomplish the goals of an individual with an acute lateral ankle sprain (LAS). CLINICAL COURSE -CHRONIC ANKLE INSTABILITYC Clinicians may include previous treatment, number of sprains, pain level, and self-report of function in their evaluation, as well as an assessment of the sensorimotor movement systems of the foot, ankle, knee, and hip during dynamic postural control and functional movements, because of their role in influencing the clinical course and estimation of time to accomplish the goals of an individual with chronic ankle instability (CAI). DIAGNOSIS/CLASSIFICATION -ACUTE LATERAL ANKLE SPRAINB Clinicians should use special tests, including the reverse anterolateral drawer test and anterolateral talar palpation in addition to the traditional anterior drawer test, and a thorough history and physical examination to aid in the diagnosis of a LAS. DIAGNOSIS/CLASSIFICATION -CHRONIC ANKLE INSTABILITYB When determining whether an individual has CAI, clinicians should use a reliable and valid discriminative instrument, such as the Cumberland Ankle Instability Tool or the Identification of Functional Ankle Instability, as well as a battery of functional performance tests that have established validity to differentiate between healthy controls and individuals with CAI. EXAMINATION -OUTCOME MEASURESA Clinicians should use validated patient-reported outcome measures, such as the Patient-Reported Outcomes Measurement Information System physical function and pain interference scales, the Foot and Ankle Ability Measure, and the Lower Extremity Functional Scale, as part of a standard clinical examination. Clinicians should utilize these before and 1 or more times after the application of interventions intended to alleviate the impairments of body function and structure, activity limitations, and participation restrictions associated with an acute LAS or CAI.C Clinicians may use the Pain Self-Efficacy Questionnaire in the acute and postacute periods after a LAS to assess effective coping strategies for pain, and the 11-item Tampa Scale of Kinesiophobia and the Fear-Avoidance Beliefs Questionnaire to assess fear of movement and reinjury and fear-avoidance beliefs in those with CAI. EXAMINATION -PHYSICAL IMPAIRMENT MEASURESA Clinicians should assess and document ankle swelling, ROM, talar translation, talar inversion, and single-leg balance in patients with an acute LAS, postacute LAS, or CAI at baseline and 2 or more times over an episode of care. Clinicians should specifically include measures of dorsiflexion, using the weight-bearing lunge test, static single-limb balance on a firm surface with eyes...
