Volleyball players are at high risk of overuse shoulder injuries, with spike biomechanics a perceived risk factor. This study compared spike kinematics between elite male volleyball players with and without a history of shoulder injuries. Height, mass, maximum jump height, passive shoulder rotation range of motion (ROM), and active trunk ROM were collected on elite players with (13) and without (11) shoulder injury history and were compared using independent samplesttests (P< .05). The average of spike kinematics at impact and range 0.1 s before and after impact during down-the-line and cross-court spike types were compared using linear mixed models in SPSS (P< .01). No differences were detected between the injured and uninjured groups. Thoracic rotation and shoulder abduction at impact and range of shoulder rotation velocity differed between spike types. The ability to tolerate the differing demands of the spike types could be used as return-to-play criteria for injured athletes.

The Relationship

This study aims to assess the relationship between scapular upward rotation (SUR) across varying humeral-elevation angles (HEAs) and shoulder isokinetic strength and ratio in professional baseball pitchers. The subjects were professional baseball pitchers (n = 16) without a history of shoulder injury in the last six months. The subject’s SUR angles were measured with the humerus elevated at HEAs of 0° (at rest), 60°, 90°, and 120° to the scapular plane. Shoulder isokinetic strength was evaluated for shoulder internal rotation (IR) and external rotation (ER) strength (PT%BW and TW%BW), and the ER/IR strength ratios were determined at 60, 120 and 180°/s using an isokinetic dynamometer. The SUR angle at an HEA of 0° was positively correlated with IR strength at 120°/s (r = 0.535) and 180°/s (r = 0.522). The SUR angle at an HEA of 60° was negatively correlated with the ER/IR strength ratios at 60°/s (r = −0.505) and 120°/s (r = −0.500). The SUR angle at an HEA of 90° was negatively correlated with the ER/IR strength ratios at 60°/s (r = −0.574; r = −0.554) and 120°/s (r = −0.521; r = −0.589) as well as with ER strength at 180°/s (r = −0.591, r = −0.556). The SUR angle at an HEA of 120° was negatively correlated with ER strength at 60°/s (r = −0.558), 120°/s (r = −0.504; r = −0.524), and 180°/s (r = −0.543) and the ER/IR strength ratio at 60°/s (r = −0.517). In this study, we found that the ratio of isokinetic strength between ER and IR became closer to the normal range on increasing the SUR angle. In particular, an HEA of 90°, which resembles the pitching motion, showed a clear relationship between SUR, shoulder ER, and the ratio of ER/IR isokinetic strength in professional baseball pitchers.

Abstract Introduction Burns crossing over a joint can result in a contracture of that joint. Axillary burns and subsequent contractures are common and may impact negatively on burn survivor rehabilitation. Positioning of burned extremities at the most lengthened position is ideal for maintenance of function and contracture prevention, 90 degrees of abduction is the most accepted position for axillary burn injuries. However, many activities of daily living require shoulder range of motion (ROM) greater than 90 degrees. The primary objective of this study was to describe and examine the incidence of paresthesia, pain, and intolerance in healthy subjects when the shoulder was placed in a position of 90 degrees or greater of shoulder abduction. Methods The subject’s nondominant upper extremity (NDE) was randomly placed in a series three of positions, including: (1) 90 degrees shoulder abduction, 30 degrees horizontal adduction with elbow extension, forearm neutral; (2) 130 degrees shoulder abduction, 30 degrees horizontal adduction, 30 degrees elbow flexion, forearm neutral; (3) 150 degrees shoulder abduction, 30 degrees horizontal adduction, 30 degrees elbow flexion, forearm neutral. Each position was maintained for a maximum of 2 hours. Subjects experiencing subjective symptoms including paresthesia lasting longer than 1 minute, pain rated greater than 3/10, and/or intolerance 2/5 was removed from the position. All subjects received at least 30 minutes of rest between positions. Results A total of 25 subjects were enrolled, mean age was 25.8 years, the majority were female (60%) and 20% had a history of NDE shoulder injury. The right arm was the dominant extremity (DE) in 88% of subjects. There were no significant differences in ROM between the DE and NDE extremity with the exception of external shoulder rotation, 94.96⁰ vs 84.8⁰ (p=.0142). Average total splint time was 136 minutes with a range of 40 – 360 minutes. Only 1 subject successfully completed all 3 splinting periods. There were 75 individual splinting events over the 3 splinting periods, and 90% of the time the splinting was stopped early. The most common reason for stopping early was paresthesia (88%) followed by pain (7%). Conclusions The positions selected represent the routine and usual care at our burn center. Patients are routinely positioned from hours to days depending on patient need. This study demonstrated that healthy subjects were unable to tolerate positioning for even two hours.

The Impact

Objectives: To investigate the impact of having previous history of inversion ankle sprain on balance tests in adolescent volleyball players. Methods: Fourty-five adolescent volleyball players with mean age of 15.26±1.03 participated in our study. Twenty-nine were uninjured (control group) and sixteen had previously experienced inversion injuries on right ankle. 9 players had the injury more than than one year ago and 7 players had it before six to twelf months. Balancing abilities were evaluated by Star Excursion Balance Test (SEBT) and Single Limb Hurdle Test (SLHT). The fact that players with history of injury had the ankle sprain at right foot led us to perform the measurements in the control group also for the right foot. We compared the results of injured and uninjured players on both tests. Results: Uninjured players' reaching distance on right foot was found out to be significantly more than in players with ankle sprain at medial and posteromedial directions of SEBT(p<.05), whereas there were no differences detected for the other directions (p>.05). For comparing athletes' performances with SLHT, finishing time was found significantly better in uninjured players (p<.05). Conclusion: Adolescent volleyball players with history of injury show lower performance on balance tests compared to uninjured players. This demonstrates that they should be given a training including balance and stabilization programs.

Background: Evidence suggests that shoulder and elbow injuries account for 31% to 37% of all National Collegiate Athletic Association (NCAA) baseball injuries, and up to 69% of NCAA baseball injuries are the result of noncontact and overuse mechanisms. Early sport specialization may contribute to the high rates of upper extremity injuries in college baseball players. Hypothesis: Higher specialization by age 13 years would be associated with worse subjective throwing arm function and a greater history of shoulder and elbow injury. Study Design: Cohort study. Level of Evidence: Level 2. Methods: Survey data were collected from college baseball players (N = 129) during midseason of the spring 2019 baseball season. Participants were stratified in low, moderate, and high specialization groups based on a 3-criteria sports specialization questionnaire. Participants’ throwing arm function was measured using the Functional Arm Scale for Throwers and the Kerlan-Jobe Orthopaedic Clinic shoulder and elbow questionnaires. Participants’ history of a shoulder or elbow injury that resulted in missing ≥2 weeks of baseball activity at any point in their baseball career was also collected. Results: The high specialization group reported worse subjective throwing arm function on the Functional Arm Scale for Throwers questionnaire than the low ( P = 0.03) and moderate ( P = 0.01) specialization groups. The high specialization group was over 5 times more likely to report a history of shoulder injury than the moderate (odds ratio [OR] = 5.42; 95% CI [1.71, 17.2]; P = 0.004) and low (OR = 5.20; 95% CI [1.87, 14.5]; P = 0.002) specialization groups, and over 3 times more likely to report a history of elbow injury than the moderate specialization group (OR = 3.77; 95% CI [1.05, 13.6]; P = 0.04). Conclusion: College baseball players that were highly specialized by age 13 years reported worse subjective throwing arm function and were more likely to have a history of upper extremity injury than players that were moderate or low specialization. Clinical Relevance: Early specialization in baseball may be detrimental to long-term upper extremity health in college baseball players.

Abstract Background The “FIFA 11 + Shoulder” programme has been reported to reduce the incidence of upper extremity injuries among soccer goalkeepers. It has also been recommended for overhead sports. The purpose of this study was therefore to investigate the effect of an 8-week “FIFA 11 + shoulder” (11 + S) programme on shoulder joint position sense (JPS), threshold to detect passive motion (TTDPM) and upper quarter Y Balance Test in young male volleyball players. Methods Thirty-two healthy young elite male volleyball players (17.49 ± 1.47 years) participated in this quasi-experimental study. Participants, recruited from two clubs participating in Iranian premier league, were randomly assigned into two groups; (1) the intervention group who performed the “FIFA 11 + shoulder” programme as their warm up protocol, three times per week, and (2) the control group who kept their routine warm up protocol meanwhile. Proprioception tests including JPS and TTDPM of internal and external rotator muscles of the dominant shoulder were recorded via the isokinetic system pro 4. The upper quarter Y Balance Test determined the shoulder dynamic stability. Results No statistically significant differences were observed for JPS and TTDPM of shoulder internal and external rotator muscles; shoulder stability however significantly increased only in the intervention group (p = 0.03, ηp2=0.02). Conclusion Upper quarter dynamic stability improvement due to the 11+S programme leads to volleyball players’ performance and may therefore contribute to a reduction in risk of sustaining injury if applied long-term. Trial registration The trial was retrospectively registered atIranian Registry of Clinical Trials with the number of IRCT20201030049193N1 at 04/12/2020.

Background and Study Aim. The purpose of this study was to examine the effect of volleyball training on the development of exercise-induced arterial hypoxemia during incremental exercise in male competitive volleyball players. Material and Methods.  Eight male amateur volleyball players (age 21±1.3 years) participated in a 6-week volleyball training program three times a week in the pre-season preparatory period. Before and after the training period, all players performed an incremental treadmill test to determine maximal oxygen uptake (VO2max), and oxyhemoglobin saturation (SaO2) was continuously measured using a pulse oximeter during the test. Maximal values of minute ventilation (VEmax), respiratory exchange ratio (RERmax), ventilatory equivalent for oxygen (VE/VO2) and carbon dioxide (VE/VCO2) were determined. Exercise-induced arterial hypoxemia (EIAH) was defined as a SaO2 decreased by at least 4% (ΔSaO2≤ −4%) from resting level. Results. All the players exhibited exercise-induced arterial hypoxemia before (ΔSaO2= –8.8±3.3%) and after (ΔSaO2= –8.31.5%) the training period. SaO2 was significantly decreased from 97.6±1% at rest to 88.7±2.7% at exhaustion before the training period, and from 97.2±1.1% at rest to 88.8±2.1% at exhaustion after training period (p < 0.001). There was no significant difference in resting and lowest SaO2 values by comparison between the before and after training (p > 0.05). There were no significant changes in VO2max, VEmax, RERmax, VE/VO2 and VE/VCO2 after training period (p > 0.05). Conclusions. The results of this study showed that volleyball players with a history of anaerobic training may exhibit EIAH, but that 6-week volleyball training has no effect on the degree of exercise-induced arterial hypoxemia.
