Objective: To explore currently accepted return-to-play tests and a jumps protocol in a single subject design following anterior cruciate ligament reconstruction. Background: The subject sustained 2 ruptures of the ACL in the left knee in a 12-month period. Both events were noncontact injuries occurring on the landing phase of a jump. A physical exam and magnetic resonance imaging were performed for both injuries by multiple orthopedic surgeons in the United States (1st rupture) and in Brazil (1st & 2nd rupture) to diagnose the injury. Treatment: Following the initial injury the subject attended 2 rehabilitation sessions per week for 16 weeks with an outpatient physical therapy clinic in the US. After the second surgery the athlete returned to the US and received treatment 6 days per week for 8 months with the University sports medicine staff. Return-to-play testing: Along with the hop test and an isokinetic knee flexion/extension test as a general protocol to determine the return-to-play, a jumps protocol to assess bilateral asymmetry and performance was also used. The symmetry index score (SI) was used to evaluate the magnitude of asymmetry. Conclusions: Following ACL reconstruction, objective data from the Hop Test, Isokinetic Test and Jumps Protocol can assist the healthcare provider in determining return-to-play status.

The purpose of this study was to determine the learning styles of Doctor of Physical Therapy (DPT) students and associate degree Physical Therapist Assistant (PTA) students and identify any association between their learning styles and examine the association between gender and age by learning style. Participants included 337 DPT and PTA students attending CAPTE accredited institutions with doctoral DPT or associate PTA programs in Tennessee and southwest Virginia. The Felder (1996) and Soloman Index of Learning Styles (ILS) was used to determine learning style preferences within 4 learning style dimensions (active-reflective, sensing-intuitive, visual-verbal, and sequential-global). Demographics included program of study, gender, age, ethnicity, and highest level of education. Participants were 18-63 years (mean age 25.87, standard deviation 5.62, median age 24); 205 (60.8%) DPT students, 132 (39.2%) PTA students; 205 (60.8%) female, 132 (39.2%) male. Five research questions with 20 null hypotheses were evaluated using Cross-tabulated tables with frequency counts, percentages, and chi square tests. Statistical significance was established using an .05 alpha. Only 1 null hypothesis was rejected (Ho51: There is no difference in the active-reflective learning style among PTA students by age). There was no significant difference between the learning styles of DPT and PTA students. Participants were found to be balanced on the active-reflective dimension, sensing on the sensing-intuitive dimension, visual on the visual-verbal dimension, and balanced on the sequential-global dimension; preferences were toward the active, sensing, visual, and sequential learning styles. This study demonstrated that DPT and PTA students have a balanced learning style with a strong preference toward active, sensing, visual, and sequential. Therefore, teaching methods should provide an instructional environment that addresses these learning style preferences. The student’s awareness of his or her learning style will enable the learner to capitalize on strengths and develop areas of weakness. This ability to employ effective learning strategies will equip an individual for the challenges of his or her chosen profession and lifelong learning.

Aims: To analyze the impact of smoking on functional aspects (nasal mucociliary transportability, pulmonary function and submaximal functional capacity) evaluating the correlation between these variables; to analyze the acute effects of smoking on the cardiorespiratory kinetics and the subjective perception of symptoms during exercise, addressing the psychological effects caused by smoking cessation and immediate smoking. Methods: Article I: A cross-sectional study with 78 smokers, age between 40 and 60 years old, in which pulmonary function (spirometry), functional capacity (six-minute walk test - 6MWT) and nasal mucociliary transportability (Saccharin Transport Time Test - STT) were evaluated; Manuscript II: Non-COPD smokers were stratified in groups according to their nicotine dependence level as low and high nicotine dependence (LND and HND, respectively), and performed treadmill exercise tests in two conditions: smoking abstinence (control) and immediately after smoking. Results: Article I: The sample presented low pack-years and so low smoking history and normal values for pulmonar function and STT. Submaximal functional capacity were normal and spirometry variables related to the pulmonary function had a positive corre... (Complete abstract click electronic access below) / Mestre

Background: Lower extremity (LE) musculoskeletal injuries in soccer players are extremely common. These injuries can result in many days of lost time in competition, severely impacting players and their respective teams. Implementation of group injury prevention programs has gained popularity due to time and cost-effectiveness. Though participation in group injury prevention programs has been successful at reducing injuries, programs often target a single injury and all players do not benefit from participation. Players with a greater number of risk factors are most likely to sustain an injury, and unfortunately, less likely to benefit from a group injury prevention program. The purpose of the proposed research is to determine if targeting these high risk players with one-on-one treatment will result in a reduction in the number of risk factors they possess. Objectives: 1) Determine the effectiveness of one-on-one intervention for reducing the number of risk factors for LE musculoskeletal injury in soccer players with 3 or more risk factors; 2) Assess the effectiveness of matched interventions on reducing the magnitude of identified risk factors. Hypothesis: Fifty percent or more of subjects receiving one-on-one intervention will have a reduction of ≥ 1 risk factor(s). Design: Quasi-experimental pretest-posttest design. Subjects: NCAA Division I men’s and women’s soccer players. Methods: All subjects were screened for modifiable risk factors using a battery of tests which assessed mobility, asymmetry in fundamental movement pattern performance, neuromuscular control, and pain with movement. Players with ≥ 3 risk factors (“high risk”) were placed in the treatment group and received one-on-one treatment from a physical therapist. An algorithm was created with interventions matched to specific deficits to determine the treatment each subject received. Subjects in the intervention group were treated twice per week for four weeks. Players with < 3 risk factors (“low risk”) were placed in the control group and did not receive one-on-one intervention. Analysis: The primary outcome measure was proportion of treatment successes, defined as a reduction of ≥ 1 risk factor(s). Secondary outcomes included analysis of within group and between group differences. Results: Thirteen subjects were treated with one-on-one intervention, with twelve having a reduction of at least 1 risk factor at posttest. The proportion of treatment successes in the intervention group was 0.923 (95%CI 0.640-0.998). The proportion of high risk subjects that became low risk at posttest was 0.846, which was statistically significant (p = 0.003). Within group differences were noted in active straight leg raise (left; p = 0.017), hip external rotation (right, p=0.000; left, p = 0.001) thoracic spine rotation (left; p=0.026), and upper quarter neuromuscular control measures (left inferolateral reach, p = 0.003; left composite, p = 0.016). A statistically significant between group difference was noted in risk factor change from pretest to posttest (p = 0.002), with the median risk factor change in the intervention group and control group being -3 and -1, respectively. Conclusion: Utilizing one-on-one interventions designed to target evidence-based risk factors is an effective strategy to reduce LE musculoskeletal injury risk factors in high risk individuals.
