Groin injuries are one of the most prevalent in male soccer players, especially due to the hip adductor muscles’ weakness which is considered as a risk factor in these injuries. The Copenhagen adduction (CA) exercise has been demonstrated to increase the strength of adductor muscles, but its effects on the architectural characteristics of adductor muscles have not been studied yet. This study aimed to analyze the effects of the CA exercise on the muscle thickness of the adductors. Twelve male U-17 soccer players were randomized into two groups: the control group with no intervention and the experimental group with an intervention based on an eight-week training with CA exercise. The muscle thickness of adductors was measured before and after the intervention using ultrasound imaging. A significant increase in muscle thickness was found in both control (p = 0.002) and experimental group (p < 0.001), but the experimental group did not show additional effects in comparison with the control group. In conclusion, an 8-week CA exercise intervention does not increase the muscle thickness of adductors in U-17 soccer players more than their regular training.

Abstract Background: Abdominal and lumbo-pelvic stability alterations may origin lower limb injuries, such as for example adductor pathology in soccer players. Imbalance can be caused by both intrinsic and extrinsic factors. Methods: This randomized controlled trial conducted over an 8-week period included 25 female footballers randomly allocated to an experimental group (isometric abdominal training and gluteus medius-specific training) or a control group (isometric abdominal training). The exercise protocol in common for both groups included three exercises: Plank, Lateral plank and Bird dog. Specific exercises for the gluteus medius were: Pelvic drop and Stabilization of the gluteus medius in knee valgus. Outcome measures were lumbo-pelvic stability and adductor strength.Results. Lumbo-pelvic stability after surgery was higher in the control group (MD: 4.84 vs MD: 9.58; p < .01) with differences in the analysis of repeated measures (p<.001), but not in group interaction (p =.26). Changes were found in adductor strength in the experimental group (MD: -2.48; p<.001 in the left adductor; MD: -1.48; p<.01 in right adductor) and control group (MD: -1.68; p<.001 in the left adductor; MD: -2.05; p<.001 in the right adductor) after the intervention, with differences in the analysis of repeated measures in left (p<.001) and right (p<.001) adductor strength.Conclusions. An abdominal and gluteal training protocol shows no advantage over a protocol of abdominal training alone for lumbo-pelvic stability and adductor strength and flexibility, while improvements are maintained at four weeks follow-up.

The natural components of the pomegranate fruit may provide additional benefits for endothelial function and microcirculation. It was hypothesized that supplementation with pomegranate extract might improve glycocalyx properties and microcirculation during acute high-intensity sprint interval cycling exercise. Eighteen healthy and recreationally active male volunteers 22–28 years of age were recruited randomly to the experimental and control groups. The experimental group was supplemented with pomegranate extract 20 mL (720 mg phenolic compounds) for two weeks. At the beginning and end of the study, the participants completed a high-intensity sprint interval cycling-exercise protocol. The microcirculation flow and density parameters, glycocalyx markers, systemic hemodynamics, lactate, and glucose concentration were evaluated before and after the initial and repeated (after 2 weeks supplementation) exercise bouts. There were no significant differences in the microcirculation or glycocalyx over the course of the study (p < 0.05). The lactate concentration was significantly higher in both groups after the initial and repeated exercise bouts, and were significantly higher in the experimental group compared to the control group after the repeated bout: 13.2 (11.9–14.8) vs. 10.3 (9.3–12.7) mmol/L, p = 0.017. Two weeks of supplementation with pomegranate extract does not influence changes in the microcirculation and glycocalyx during acute high-intensity sprint interval cycling-exercise. Although an unexplained rise in blood lactate concentration was observed.

Abstract Background and Purpose. Passive joint mobilization is commonly used by physical therapists as an intervention for acute ankle inversion sprains. A randomized controlled trial with blinded assessors was conducted to investigate the effect of a specific joint mobilization, the anteroposterior glide on the talus, on increasing pain-free dorsiflexion and 3 gait variables: stride speed (gait speed), step length, and single support time. Subjects. Forty-one subjects with acute ankle inversion sprains (&lt;72 hours) and no other injury to the lower limb entered the trial. Methods. Subjects were randomly assigned to 1 of 2 treatment groups. The control group received a protocol of rest, ice, compression, and elevation (RICE). The experimental group received the anteroposterior mobilization, using a force that avoided incurring any increase in pain, in addition to the RICE protocol. Subjects in both groups were treated every second day for a maximum of 2 weeks or until the discharge criteria were met, and all subjects were given a home program of continued RICE application. Outcomes were measured before and after each treatment. Results. The results showed that the experimental group required fewer treatment sessions than the control group to achieve full pain-free dorsiflexion. The experimental group had greater improvement in range of movement before and after each of the first 3 treatment sessions. The experimental group also had greater increases in stride speed during the first and third treatment sessions. Discussion and Conclusion. Addition of a talocrural mobilization to the RICE protocol in the management of ankle inversion injuries necessitated fewer treatments to achieve pain-free dorsiflexion and to improve stride speed more than RICE alone. Improvement in step length symmetry and single support time was similar in both groups.

This study was undertaken to investigate the effect of two different concepts in a training program on muscle thickness and anaerobic power in trained cyclists. Twenty-six mountain bike cyclists participated in the study and were divided into an experimental group (E), which performed polarized training, comprising sprint interval training (SIT), high-intensity interval training (HIIT), and endurance training (ET), and a control group (C), which performed HIIT and ET. The experiment was conducted over the course of 9 weeks. Laboratory tests were performed immediately before and after the conducted experiment, including an ultrasound measurement of the quadriceps femoris muscle thickness and a sprint interval testing protocol (SITP). During the SITP, the cyclists performed 4 maximal repetitions, 30 s each, with a 90-s rest period between the repetitions. SITP was performed to measure maximal and mean anaerobic power. As a result of the applied training program, the muscle thickness decreased and the mean anaerobic power increased in the experimental group. By contrast, no significant changes were observed in the control group. In conclusion, a decrease in muscle thickness with a concomitant increase in mean anaerobic power resulting from the polarized training program is beneficial in mountain bike cycling.

Abstract Background In recent years, many studies focused on the use of robotic devices for both the assessment and the neuro-motor reeducation of upper limb in subjects after stroke, spinal cord injuries or affected by neurological disorders. Contrarily, it is still hard to find examples of robot-aided assessment and rehabilitation after traumatic injuries in the orthopedic field. However, those benefits related to the use of robotic devices are expected also in orthopedic functional reeducation. Methods After a wrist injury occurred at their workplace, wrist functionality of twenty-three subjects was evaluated through a robot-based assessment and clinical measures (Patient Rated Wrist Evaluation, Jebsen-Taylor and Jamar Test), before and after a 3-week long rehabilitative treatment. Subjects were randomized in two groups: while the control group (n = 13) underwent a traditional rehabilitative protocol, the experimental group (n = 10) was treated replacing traditional exercises with robot-aided ones. Results Functionality, assessed through the function subscale of PRWE scale, improved in both groups (experimental p = 0.016; control p < 0.001) and was comparable between groups, both pre (U = 45.5, p = 0.355) and post (U = 47, p = 0.597) treatment. Additionally, even though groups’ performance during the robotic assessment was comparable before the treatment (U = 36, p = 0.077), after rehabilitation the experimental group presented better results than the control one (U = 26, p = 0.015). Conclusions This work can be considered a starting point for introducing the use of robotic devices in the orthopedic field. The robot-aided rehabilitative treatment was effective and comparable to the traditional one. Preserving efficacy and safety conditions, a systematic use of these devices could lead to decrease human therapists’ effort, increase repeatability and accuracy of assessments, and promote subject’s engagement and voluntary participation.

Abstract Background Adaptive seating is commonly used as an intervention method to enhance postural control. The aim of this study is to investigate the effect of using therapy ball as a seat alternative to using typical chair on grasping and visual motor integration in the children with hemiparetic cerebral palsy. For this aim, thirty children with hemiparetic cerebral palsy from both sexes were included in this study. The children ages ranged from 3 to 6 years old. The degree of spasticity was 1 to 1+ according to modified Ashworth scale. The children were able to sit independently and follow instructions. Children were randomly assigned into two groups (experimental group and control group). Each child was evaluated before and after 3 successive months of selected occupational therapy exercises program. All the children of both groups received the same selected occupational therapy exercises program, but the children in the experimental group performed the exercises while sitting on therapy ball, and the children in the control group performed the exercises while sitting on typical chair. Results There was a significant improvement in the measured variables for both groups after treatment. The post-treatment results of the two groups of grasping and visual motor integration for age equivalent scores revealed significant difference (p=0.008 and p=0.011 respectively) in favor of the experimental group. Conclusions Therapy ball could be used as a seat alternative to using typical chair to facilitate visual motor integration and grasping in the children with hemiparetic cerebral palsy.

Background: Improving balance-related ability is an important goal in stroke rehabilitation. Evidence is needed to demonstrate how this goal could be better achieved. Aim: Determine if trunk exercises on unstable surfaces would improve trunk control and balance for persons in the subacute stage of stroke. Design: An assessor-blind randomized controlled trial. Setting: Inpatients in the department of rehabilitation in a general hospital. Population: Patients who suffered a first-time stroke with onset from one to six months. Methods: Inpatients with stroke were assigned to upper limb exercises (control group, n = 17) or trunk exercises on unstable surfaces (experimental group, n = 18) to receive training twice a week for six weeks, in addition to their daily conventional stroke rehabilitation. Sensorimotor function tests, including hand grip, plantar sensitivity, stroke rehabilitation assessment of movement and Fugl-Meyer lower extremity motor scale, and clinical outcome assessments, including Trunk Impairment Scale and 6 m walk test, were conducted before and after six weeks of training. The center of the pressure area while maintaining static posture and peak displacement while leaning forward, as well as the average speed of raising the unaffected arm, were measured in sitting without foot support, sitting with foot support and standing to reflect trunk control, sitting balance and standing balance, respectively. Results: The between-group differences in the sensorimotor functions were nonsignificant before and after training. Compared with the control group, the experimental group had significantly greater forward leaning and faster arm raising in sitting without foot support, higher Trunk Impairment Scale total score, and shorter 6 m walking time after training, but not before training. Conclusion: Trunk exercises on unstable surfaces could further improve trunk control, the ability to raise the unaffected arm rapidly in sitting, and walking for persons in the subacute stage of stroke. This intervention may be considered to be included in stroke rehabilitation.

BACKGROUND and OBJECTIVE: Caring for a child with a disability affects musculoskeletal system pain, fatigue, sleep quality, and anxiety of the mothers. The purpose of the study was to determine the effectiveness of breathing exercises in mothers with chronic non-specific low back pain (NLBP). METHODS: Forty-three mothers with chronic NLBP were randomly assigned to the experimental group (n= 23) and the control group (n= 20). The experimental group received breathing exercises with core stabilization exercises (BSET) for three sessions a week for 8 weeks, and the control group performed stabilization exercises (SET) only, for the same period. Pain severity, fatigue, anxiety, and sleep quality were evaluated before and after the treatment programs. RESULTS: After the treatment programs, significant differences were observed in pain, fatigue, and sleep quality in both groups (p< 0.05). However, the BSET group showed a significantly better improvement in anxiety levels and sleep quality than the SET group (p< 0.05). CONCLUSIONS: The improvements in pain, fatigue and sleep quality were seen in both groups after treatment programs. It is recommended breathing exercises are added to core stabilization programs to provide greater improvements in anxiety level and sleep quality for mothers of children with disabilities, who have NLBP.

Background. Literature suggests cardiorespiratory fitness as a factor influencing cognitive improvement. The authors of the present study sought to investigate if cardiorespiratory fitness related to cognitive performance after an acute bout of game-based exercise of different intensities in adolescents. Methods.  As many as 37 adolescents (24 girls and 13 boys, 15–16 years of age) were assigned to three groups: experimental group 1 (EX 1), experimental group 2 (EX 2), and control (CON) group. The experimental groups experienced different levels of exercise intensity (EX 1 – light intensity, EX 2 – vigorous intensity). The Shuttle Run Test was performed a week before the intervention and VO2peak was calculated. Symbol Digit Modalities Test (SDMT) was evaluated before and after the acute intervention. A 2 x 3 repeated-measures ANOVA was used to analyze the SDMT and Pearson’s correlation coefficient was used to estimate the relationship between the cognitive performance (SDMT) and cardiorespiratory fitness (VO2peak). Results. Comparing the SDMT scores before and after the intervention, there were no differences found between the three groups. Neither in any of the experimental groups nor in the control group was a relationship between the SDMT score and VO2peak observed. Conclusion. Acute game-based exercise intervention did not prove to improve cognitive performance effectively. The authors of the present paper did not confirm the relationship between cardiorespiratory fitness and cognitive performance in adolescents. Keywords: exercise, cognitive performance, cardiorespiratory fitness.

BACKGROUND: Gait deviations and spasticity are common impairments seen in children with cerebral palsy (CP) and may interfere with functional performance and effective walking pattern. Lidocaine iontophoresis is effective for reducing muscle spasticity in adults. PURPOSE: To investigate the effect of lidocaine epinephrine iontophoresis combined with exercises on gait and spasticity in children with spastic hemiplegic cerebral palsy (HCP). METHODS: Thirty children with spastic HCP aged 4–6 (5.20±0.32) years were randomly assigned to the experimental group (n = 15) and control group (n = 15). Children in both groups received one hour of exercises, three times a week for three months. Children in the experimental group received 2% lidocaine iontophoresis immediately before the exercises. The lidocaine iontophoresis was delivered for 20 minutes (1mA/min). Spatio-temporal gait parameters were assessed within one week before and after the intervention using 3D motion analysis. Surface electromyography was used to assess muscle tone using H/M ratio of the soleus muscle. ANOVA was used to investigate the differences between experimental and control groups. Statistical significance was set at P value less than 0.05. RESULTS: There was no difference between groups at baseline. Post-intervention, the experimental group showed significant improvements when compared to the control group for gait speed (p = 0.03), stride length (p = 0.04), cadence (p = 0.0001), cycle time (p = 0.0001), and H/M ratio (p = 0.02). CONCLUSION: Lidocaine iontophoresis combined with exercises was effective in improving gait spatiotemporal parameters and reducing spasticity in children with CP.
