Context: Neuromuscular control deficit has been reported in people with chronic ankle instability (CAI) and hopping exercises have been recommended as a functional training tool to prevent lower limb injury, but its effects on lower-extremity neuromuscular control in those with CAI are unclear. Objective: To investigate the effect of hop stabilization training on neuromuscular control and self-reported function in college basketball players with CAI. Study Design: A randomized controlled trial. Setting: Research Laboratory. Patients (or Other Participants): A total of 28 college basketball players with CAI were randomly assigned to the experimental hop stabilization group (age = 22.78 [3.09] y, weight = 82.59 [9.51] kg, and height = 187.96 [7.93] cm) or the control group (age = 22.57 [2.76] y, weight = 78.35 [7.02] kg, and height = 185.69 [7.28] cm). Intervention: Participants in the experimental group performed supervised hop stabilization exercises 3 times per week for 6 weeks. The control group received no intervention. Main Outcome Measures: Preparatory and reactive muscle activation levels and muscle onset time were assessed from 8 lower-extremity muscles during a jump-landing task before and after the 6-week training program. Results: Significant improvements in preparatory muscle activation, reactive muscle activation, and muscle onset time were noted across the lower-extremity in the experimental group relative to the control group (P < .05). Self-reported function also improved in the experimental group relative to the control group (P < .05). Conclusions: These findings demonstrate that 6 weeks of hop stabilization training is effective in improving neuromuscular control and self-reported function in college basketball players with CAI. Hop stabilization exercises can be incorporated into the rehabilitation program for CAI.

Context Hopping exercises are recommended as a functional training tool to prevent lower limb injury, but their effects on lower extremity biomechanics in those with chronic ankle instability (CAI) are unclear. Objective To determine if jump-landing biomechanics change after a hop-stabilization intervention. Design Randomized controlled clinical trial. Setting Research laboratory. Patients or Other Participants Twenty-eight male collegiate basketball players with CAI were divided into 2 groups: hop-training group (age = 22.78 ± 3.09 years, mass = 82.59 ± 9.51 kg, height = 187.96 ± 7.93 cm) and control group (age = 22.57 ± 2.76 years, mass = 78.35 ± 7.02 kg, height = 185.69 ± 7.28 cm). Intervention(s) A 6-week supervised hop-stabilization training program that consisted of 18 training sessions. Main Outcome Measure(s) Lower extremity kinetics and kinematics during a jump-landing task and self-reported function were assessed before and after the 6-week training program. Results The hop-stabilization program resulted in improved self-reported function (P &lt; .05), larger sagittal-plane hip- and knee-flexion angles, and greater ankle dorsiflexion (P &lt; .05) relative to the control group. Reduced frontal-plane joint angles at the hip, knee, and ankle as well as decreased ground reaction forces and a longer time to peak ground reaction forces were observed in the hopping group compared with the control group after the intervention (P &lt; .05). Conclusions The 6-week hop-stabilization training program altered jump-landing biomechanics in male collegiate basketball players with CAI. These results may provide a potential mechanistic explanation for improvements in patient-reported outcomes and reductions in injury risk after ankle-sprain rehabilitation programs that incorporate hop-stabilization exercises.

Context The literature on gait kinematics and muscle activation in chronic ankle instability (CAI) is limited. A comprehensive evaluation of all relevant gait measures is needed to examine alterations in gait neuromechanics that may contribute to recurrent sprain. Objective To compare walking neuromechanics, including kinematics, muscle activity, and kinetics (ie, ground reaction force [GRF], moment, and power), between participants with and those without CAI by applying a novel statistical analysis to data from a large sample. Design Controlled laboratory study. Setting Biomechanics laboratory. Patients or Other Participants A total of 100 participants with CAI (49 men, 51 women; age = 22.2 ± 2.3 years, height = 174.0 ± 9.7 cm, mass = 70.8 ± 14.4 kg) and 100 individuals without CAI serving as controls (55 men, 45 women; age = 22.5 ± 3.3 years, height = 173.1 ± 13.3 cm, mass = 72.6 ± 18.7 kg). Intervention(s) Participants performed 5 trials of walking (shod) at a self-selected speed over 2 in-ground force plates. Main Outcome Measure(s) Three-dimensional GRFs, lower extremity joint angles, internal joint moments, joint powers, and activation amplitudes of 6 muscles were recorded during stance. Results Compared with the control group, the CAI group demonstrated (1) increased plantar flexion or decreased dorsiflexion, increased inversion or decreased eversion, decreased knee flexion, decreased knee abduction, and increased hip-flexion angles; (2) increased or decreased inversion, increased plantar flexion, decreased knee extension, decreased knee abduction, and increased hip-extension moments; (3) increased vertical, braking, and propulsive GRFs; (4) increased hip eccentric and concentric power; and (5) altered muscle activation in all 6 lower extremity muscles. Conclusions The CAI group demonstrated a hip-dominant strategy by limiting propulsive forces at the ankle while increasing force generation at the hip. The different walking neuromechanics exhibited by the CAI group could represent maladaptive strategies that developed after the initial sprain or an injurious gait pattern that may have predisposed the participants to their initial injuries. Increased joint loading and altered kinematics at the foot and ankle complex during initial stance could affect the long-term health of the ankle articular cartilage.

This study aimed to compare the effects of dry needling (DN) versus placebo DN applied to the peroneus longus (PL) and tibialis anterior (TA) on neuromuscular control and static postural control in basketball players with chronic ankle instability (CAI). A single-blinded randomized controlled trial was conducted. Thirty-two male and female basketball players with CAI were randomly assigned to receive either DN (n = 16) or placebo DN (n = 16). Pre-activation amplitudes of PL and TA were assessed with surface electromyography (EMG) during a dynamic landing test. Center of pressure (CoP) displacement and sway variability in anterior-posterior (AP) and medio-lateral (ML) directions were measured with a force platform during a single leg balance test (SLBT). Measures were obtained prior to a single DN intervention, immediately after, at 48 h, and 1 month after. The DN group displayed a significant increase in PL and TA pre-activation values, which were maintained 1 month later. Significant reductions in the ML and AP displacements and sway variability of CoP were found for the DN group. These results showed improvements in feedback/feed-forward strategies following DN, including enhanced neuromuscular control and static postural control, with the potential to become a convenient and accessible preventive treatment in CAI subjects.

Context Ankle sprains are among the most common musculoskeletal injuries, and many individuals with ankle sprains develop chronic ankle instability (CAI). Individuals with CAI exhibit proprioceptive and postural-control deficits, as well as altered osteokinematics, during gait. Neuromuscular activity is theorized to play a pivotal role in CAI, but deficits during walking are unclear. Objective To compare motor-recruitment patterns as demonstrated by surface electromyography amplitudes between participants with CAI and healthy control participants during walking. Design Descriptive laboratory study. Setting Laboratory. Patients or Other Participants Fifteen adults with CAI (5 men, 10 women; age = 23 ± 4.2 years, height = 173 ± 10.8 cm, mass = 72.4 ± 14 kg) and 15 matched healthy control adults (5 men, 10 women; age = 22.9 ± 3.4 years, height = 173 ± 9.4 cm, mass = 70.8 ± 18 kg). Intervention(s) Participants walked shod on a treadmill while surface electromyography signals were recorded from the anterior tibialis, peroneus longus, lateral gastrocnemius, rectus femoris, biceps femoris, and gluteus medius muscles. Main Outcome Measure(s) Preinitial contact amplitude, postinitial contact amplitude, time of activation relative to initial contact, and percentage of activation time across the stride cycle were calculated for each muscle. Results Time of activation for all muscles tested occurred earlier in the CAI group than in the control group. The peroneus longus was activated for a longer duration across the entire stride cycle in the CAI group (36.0% ± 10.3%) than the control group (23.3% ± 22.2%; P = .05). No differences were noted between groups for measures of electromyographic amplitude at either preinitial or postinitial contact (P &gt; .05). Conclusions We identified differences between the CAI and control groups in the timing of muscle activation relative to heel strike in multiple lower extremity muscles and in the percentage of activation time across the entire stride cycle in the peroneus longus muscle. Individuals with CAI demonstrated neuromuscular-activation strategies throughout the lower extremity that were different from those of healthy control participants. Targeted therapeutic interventions for CAI may need to be focused on restoring normal neuromuscular function during gait.

More innovative technologies are used worldwide in patient’s rehabilitation after stroke, as it represents a significant cause of disability. The majority of the studies use a single type of therapy in therapeutic protocols. We aimed to identify if the association of virtual reality (VR) therapy and mirror therapy (MT) exercises have better outcomes in lower extremity rehabilitation in post-stroke patients compared to standard physiotherapy. Fifty-nine inpatients from 76 initially identified were included in the research. One experimental group (n = 31) received VR therapy and MT, while the control group (n = 28) received standard physiotherapy. Each group performed seventy minutes of therapy per day for ten days. Statistical analysis was performed with nonparametric tests. Wilcoxon Signed-Rank test showed that both groups registered significant differences between pre-and post-therapy clinical status for the range of motion and muscle strength (p < 0.001 and Cohen’s d between 0.324 and 0.645). Motor Fugl Meyer Lower Extremity Assessment also suggested significant differences pre-and post-therapy for both groups (p < 0.05 and Cohen’s d 0.254 for the control group and 0.685 for the experimental group). Mann-Whitney results suggested that VR and MT as a therapeutic intervention have better outcomes than standard physiotherapy in range of motion (p < 0.05, Cohen’s d 0.693), muscle strength (p < 0.05, Cohen’s d 0.924), lower extremity functionality (p < 0.05, Cohen’s d 0.984) and postural balance (p < 0.05, Cohen’s d 0.936). Our research suggests that VR therapy associated with MT may successfully substitute classic physiotherapy in lower extremity rehabilitation after stroke.

Abstract Background TheraTogs promotes proprioceptive sense of a child with cerebral palsy and improves abnormal muscle tone, posture alignment, balance, and gait. Therefore, the aim of this study was to investigate the efficacy of TheraTogs orthotic undergarment on gait pattern in children with dyskinetic cerebral palsy. Thirty children with dyskinetic cerebral palsy were selected for this randomized controlled study. They were randomly assigned to (1) an experimental group that received TheraTogs orthotic undergarment (12 h/day, 3 days/week) plus traditional physical therapy for 3 successive months and (2) a control group that received only traditional physical therapy program for the same time period. Gait parameters were measured at baseline and after 3 months of intervention using Pro-Reflex motion analysis. Results Children in both groups showed significant improvements in the gait parameters (P < 0.05), with significantly greater improvements in the experimental group than in the control group. Conclusions The use of TheraTogs may have a positive effect to improve gait pattern in children with dyskinetic cerebral palsy. Trial registration This trial was registered in the ClinicalTrial.gov PRS (NCT03037697).

Background Previous research indicates low disposal rates of excess postoperative narcotics, leaving them available for diversion or abuse. This study examined the effect of introducing a portable disposal device on excess opiate opioid disposal rates after lower extremity orthopaedic surgery. Methods This was a single site randomized control trial within an outpatient orthopaedic clinic. All patients 18 years or older, undergoing outpatient foot and ankle surgery between December 1, 2017 and August 1, 2018 were eligible. Patients were prospectively enrolled and randomized to receive standard opioid disposal instructions or a drug deactivation device at 2-week postoperative appointments. Participants completed an anonymous survey at 6-week postoperative appointments. Results Of the 75 patients surveyed, 68% (n = 26) of the experimental group and 56% (n = 21) of the control group had unused opioid medication. Of these, 84.6% of patients who were given Deterra Drug Deactivation System deactivation pouches safely disposed of excess medication, compared with 38% of controls (P = .003). When asked if they would use a disposal device for excess medication in the future, 97.4% (n = 37) of the experimental and 83.8% (n = 31) of the control group reported that they would. Conclusions Providing a portable disposal device with postoperative narcotic prescriptions may increase safe disposal rates of excess opioid medication following lower extremity orthopaedic surgery.

AbstractObjectivesObjective of the study is to investigate whether Soft tissue mobilization (STM) can assist with static stretching to improve hamstring flexibly.MethodsThe design of the study was repeated measure design. The study was conducted at the physical therapy laboratory of Jamia Hamdard University, New Delhi. Participants included 78 healthy males with hamstring tightness, randomly assigned to either the control group (static stretching) or the experimental group (STM and static stretching). The experimental group received five sets of four different STM techniques, followed by two sets of 30-s static stretches 3 days per week over the course of 12 weeks. The control group received 5 min of sham ultrasound with an inactive probe prior to static stretching. Active knee extension test (AKE) was the outcome measure.ResultsBoth groups showed significant improvement in AKE compared with the baseline measurements. With ingroup analysis showed a significant difference in AKE across all measured time periods (weeks 4, 8, and 12) with pre-test in both groups (p<0.05). No significant difference in AKE improvement was found between groups (p>0.05).ConclusionThe results of this study show that STM prior to static stretching does not significantly improve hamstring flexibility among healthy individuals. Although this study cannot be generalized, the results may be useful for evidence-based practice in the management of hamstring tightness.

Background and Objectives: The purpose of this study was to investigate the effects of microcurrent stimulation on pain, shoulder function, and grip strength in patients with rotator cuff repair. Materials and Methods: This randomized single-blind controlled trial was conducted on inpatients of the rehabilitation department, and included 28 patients who underwent rotator cuff repair. Participants were randomly assigned to the experimental group (n = 14), treated with microcurrent stimulation, and the control group (n = 14), treated with false microcurrent stimulation. The microcurrent stimulation administered to the experimental group underwent general physical therapy and microcurrent stimulation three times a week for 4 weeks. Results: Changes in pain, range of motion in shoulder, simple shoulder test, and grip strength were assessed before and after the intervention. Both groups showed a significant decrease in pain and shoulder function (t = 27.412, 22.079, 19.079, and 18.561; p < 0.001), and grip strength showed a significant increase (t = −8.251 and −9.946; p < 0.001). The experimental group that underwent microcurrent stimulation exhibited a significant effect on pain, shoulder function, and grip strength compared with the control group that underwent false microcurrent stimulation (t = −2.17, −2.22, and 2.213; p = 0.039, 0.035, and 0.036). Conclusions: This study confirmed that microcurrent stimulation is effective for the treatment of rotator cuff repair patients.

An intensive physical exercise program could lead to a decrease in immune system function. Effects of long-term supplementation of bovine colostrum on the response of immune function on physical exercise test in athletes were examined. Twenty-seven elite female basketball players (age 16–19) were randomly assigned to either an experimental group or a control group. Eventually, n = 11 athletes completed intervention in the experimental group (3.2 g bovine colostrum orally twice a day for 24 weeks), while n = 9 athletes in the control group were given a placebo. Before the supplementation, after 3 and 6 months, subjects performed the physical exercise stress test. Before, just after, and 3 h after physical exercise testing, blood was drawn and immune system indicators were examined. Plasma interleukin (IL)-1alpha, IL-2, IL-10, IL-13, tumor necrosis factor (TNF) alpha, creatine kinase (CK MM), immunoglobulin G (IgG), insulin-like growth factor 1 (IGF1), and WBC, lymphocyte (LYM), monocyte (MON), and granulocyte (GRA) were measured. A statistically significant change in IL-10 in response to the exercise program during the supplementation period in both groups was observed (p = 0.01). However, the results of the rest of the comparisons were statistically insignificant (p > 0.05). Contrary to our initial hypothesis, there were no significant effects of bovine supplementation on the dynamics of immune system function indicators.
