Objective
The purpose of this case report is to describe the management of a professional soccer player with a knee Posterior Cruciate Ligament (PCL) tear using platelet-rich plasma (PRP) injections.
Clinical Features
A case of magnetic resonance imaging (MRI) confirmed type II injury of PCL with correlated physical signs of PCL insufficiency in a 21-year-old, white, professional soccer player is reported herein.
Intervention and Outcome
A PRP regimen was administered intra-articularly in 3 applications at weekly intervals to the affected knee. Follow-up assessment showed complete, pain-free ROM, a clinically normal joint, and complete ligament healing after PRP. The healing was supported by magnetic resonance imaging performed 48 months after the treatment.
Conclusion
This is the first reported case of a PCL type II injury in a professional soccer player with an isolated PRP application. This case expands the treatment options for PCL injuries and highlights another potential effect of PRP within the field of regenerative medicine.

This study aimed to measure muscle activity during seated trunk strength training using resistance-wheeled training equipment at different resistance levels.
Methods
The participants were 19 healthy males. Resistance-wheeled training equipment, such as the small vehicle used in this study, had a mechanical braking function that locked the wheels and unlocked the brakes while only pressing downward with a constant force. The subjects moved the equipment forward and backward on a desk with an unlocked brake status. The participants performed under 3 conditions; (1) unlocked with no force, (2) unlocked with low force, and (3) unlocked with high force.
Results
Muscle activity increased significantly with increasing locked strength in the deltoid posterior, internal and external oblique, rectus abdominis, erector spinae thorax, and lumbar muscles. Some muscles reached over 50% of the maximum voluntary contraction when unlocked with a high force.
Conclusion
The muscle activity measured during trunk training that exceeded 50% of the maximum voluntary activation level corresponds to be sufficiently high for strength training and the activity level required for muscle hypertrophy. We believe that this research equipment may be a useful seated trunk strength training device.

The purpose of this study was to identify the point and lifetime prevalence of low back pain (LBP) among dressage riders and identify riding-related variables that may precipitate LBP.
Methods
A cross-sectional, exploratory, quantitative study was conducted using an online questionnaire. One hundred dressage riders competing at preliminary and higher levels were recruited at the South African Equestrian Federation’s registered shows. Frequencies and descriptive statistics were performed on each question in addition to cross-tabulations for associations between variables or differences between riding practices and experiences.
Results
Participants were between the ages of 18 and 66 years. The questionnaire identified that 71% of participants reported point prevalence of LBP and 56% reported lifetime prevalence of LBP. Spearman ρ correlations showed positive correlations between how often participants believed their LBP was horse riding–related and how often they experienced LBP while competing/riding (r[75] = 0.46, P = .00) and how often their pain got worse with competing/riding (r[75] = 0.49, P = .00) and negative correlations with the number of hours spent in sitting trot and an increase in LBP (r[75] = −0.13, P = .28) and the number of hours spent cantering and an increase in LBP (r[75] = −0.19, P = .94).
Conclusion
This study reports point and lifetime prevalence of LBP among competitive dressage riders in South Africa. Training/riding-specific horse gaits were associated with LBP in dressage riders.

This study aimed to examine the reliability and agreement of goniometric measurements in assessing the range of motion (ROM) within the shoulder joint utilizing a 3D marker-based motion analysis system.
Methods
The study comprised 30 healthy volunteers and 35 patients diagnosed with unilateral restricted shoulder range of motion (ROM). Agreement analysis was conducted using Bland–Altman methods, while intra- and interobserver reliability for flexion, abduction, internal rotation, and external rotation measurements was assessed using the Intraclass Correlation Coefficient (ICC).
Results
When goniometric measurements were compared with the 3D method, ICC values in the patient group were found to be 0.85 for flexion, 0.81 for abduction, 0.80 for external rotation, and 0.74 for internal rotation. In healthy individuals, the values were found to be 0.80, 0.90, 0.56, and 0.69. Additionally, all measurements fell within acceptable limits of agreement, with no significant differences in measurement biases, except for internal rotation.
Conclusion
This study highlights that the goniometer exhibited higher reliability when assessing movements with larger ROM, particularly within heterogeneous groups like those with injured shoulders. However, its reliability decreased when used in homogeneous groups, such as healthy individuals, especially when evaluating movements with narrower ROM, such as rotations. These findings emphasize the need for a nuanced interpretation of results in clinical and research settings when assessing shoulder joint mobility.

The purpose of the study was to determine the relationship between heart rate, rate of perceived exertion, and blood lactate concentration in recreational cricket players between the modified Bruce protocol and the continuous backward medicine ball throw (CBMB) test. The goal was to develop an alternate, inexpensive test for submaximal exercise testing.
Methods
Thirteen recreational cricket players were recruited from Jamia Millia Islamia, New Delhi. The heart rate and rate of perceived exertion were recorded at rest during standing, at the time of reaching the ventilatory threshold, and after 1, 2 and 3 minutes of the recovery period during the modified Bruce protocol and continuous backward medicine ball throw test. The blood lactate levels were recorded at rest while standing, at the time of reaching VT, and after 3 minutes of the recovery period during the modified Bruce protocol and the continuous backward medicine ball throw (CBMB) test, and also at the end of stage 1 for modified Bruce protocol and at the end of 10 reps for continuous backward medicine ball throw test.
Results
The mean age of the recreational cricket player in the study was 22.23±1.87 years. Significant ‘r’ values were found for heart rate (r=.975, p<.001), and blood lactate concentration (r=.824, p=.001) between the modified Bruce protocol and the continuous backward medicine ball throw test.
Conclusion
The continuous backward medicine ball throw (CBMB) test for submaximal exercise testing showed validity when compared to the Bruce protocol in recreational cricket players.

Objective
The objective of this review is to summarize current information for chiropractors on Metabolic Syndrome (MetS) related to prevention and health promotion.
Methods
Research staff and faculty of a doctor of chiropractic program performed a narrative review, which included guidelines from the United States Preventative Task Force and meta-analyses. We performed a PubMed search of meta-analyses published in English between 2019 to 2024, indexed with the Medical Subject Heading “Metabolic Syndrome,” and which had free-text availability. Meta-analyses were included if they were relevant to chiropractic practice and health promotion/prevention.
Results
The PubMed search resulted in 156 citations of which 38 meta-analyses were selected for inclusion in this review. Clinical intervention strategies identified that may reduce MetS risk and negative sequelae include screening for MetS, such as measuring waist circumference, blood pressure and biomarker levels. In addition, chiropractors can support lifestyle behavior changes that may help patients lose weight such as increasing protein intake from plant-based diets, increasing physical activity, optimizing sleep and reducing sugar-sweetened beverage consumption.
Conclusions
This review summarizes current information on MetS related to prevention and health promotion. Chiropractors and other health care professionals knowledgeable of the lifestyle-related risk factors associated with MetS can use this information to better screen and manage at-risk patients.
