    An analysis of the combined effects of swimming and overhead throwing on the shoulder complexes of male first division waterpolo players
    (2021-05-10) Gibb, Conor Beckett; Matkovich, Grant
    Background Abstract Waterpolo is often compared to other sports, mainly swimming and overhead throwing sports. Swimming favours a posture of glenohumeral internal rotation and horizontal adduction. Overhead throwing sports can characteristically cause posterior shoulder immobility with a loss in glenohumeral internal rotation and horizontal adduction. Based on the fact that waterpolo players combine both swimming and overhead throwing whilst playing and training, it is the purpose of this study to investigate the sport-specific characteristics of the shoulder complexes of waterpolo players in an effort to determine how these unique characteristics may relate to the development of overuse injuries. Aim The aim of this study is to compare the dominant and non-dominant shoulder complexes of male water polo players in terms of posture, range of motion and sport- specific overuse injuries in order to develop an understanding of the combined effects of swimming and overhead throwing on the shoulders of water polo players. Methods The study used an observational based research design and consisted of 33 male waterpolo players currently competing in the Kwa-Zulu Natal mens 1st division waterpolo league. Participants underwent a shoulder digital posture examination as well as a shoulder-complex physical examination consisting of range of motion and orthopaedic testing which was then compared between the dominant and non- dominant shoulders. Participants were assessed for the presence of rotator cuff injury, glenoid labrum and LHBT injury, and anterior glenohumeral instability using the following physical tests: Empty can test, painful arc test, external rotation resistance, Hawkins-Kennedy test, Neer test, Yergassons test, Biceps Load test II, and the apprehension-relocation-surprise test. Glenohumeral range of motion was assessed using manual goniometry to measure passive internal and external rotation and horizontal adduction. Statistical analysis was performed using IBM SPSS version 27 statistical analysis software. Paired tests were used to compare outcomes from the dominant and non-dominant shoulders of the participants. To compare the posture measurements, as well as injuries present between the dominant and non-dominant shoulders, McNemar’s chi square tests were used. To compare the Range of motion measurements between the dominant and non-dominant shoulders, paired t-tests were used. A p value < 0.05 was considered statistically significant. Results Forward head posture with rounded shoulders was extremely common, with 73% of the participants in this study displaying a bilateral forward shoulder position ranging from moderate to severe, and 45% of participants displaying a bilateral forward head posture ranging from mild to severe. Glenohumeral internal and external rotation ROM measurements showed no difference between sides. There was a borderline significant difference (p=0.05) in the horizontal adduction measurements, with the non- dominant side showing greater values. The only injury test that yielded significant results was the empty can test for supraspinatus injury that had a higher prevalence for being positive on the dominant side. Conclusion The results of this study suggest that water polo players are prone to the development of a bilaterally equal forward head posture with rounded shoulders and are susceptible to similar mechanisms of bilateral overuse injury as swimmers. In addition, the dominant shoulders of these athletes are susceptible to damage caused by the repetitive, traumatic forces experienced by the posterior cuff musculature and posterior glenohumeral joint capsuloligamentous structures during the follow-through and deceleration phases of overhead throwing, resulting in an increased risk of supraspinatus-specific rotator cuff injury and a loss of glenohumeral horizontal adduction that potentially increases the risk of glenoid labrum and LHBT injury.

    The immediate effect of myofascial trigger point dry needling of four shoulder girdle muscles on the 100m lap- times of asymptomatic competitive swimmers in Bloemfontein
    (2017) Schmidt-Kinsman, Sarah; Harpham, Graeme John; Korporaal, Charmaine Maria
    Background Competitive swimming, as with most other sports that are participated in at more than a recreational level, involves a substantial amount of training. Training excessively results in the overuse of muscles. The overuse of muscles commonly causes the production of myofascial trigger points (MFTPs) within the overworked muscles. The presence of MFTPs is a condition known as myofascial pain syndrome (MPS). Myofascial trigger points may be active or latent. Either way, they produce a wide range of effects. This study focuses on the effect of reduced muscle strength. Muscle strength is essential to athletes as it determines performance. Swimmers with MFTPs will not perform at their full ability. Dry needling is an effective form of treatment for MFTPs as it produces immediate relief from the effects of MFTPs. There is not enough information on the immediate effects of dry needling on athlete performance. Since dry needling brings about the immediate relief of MFTPs, this study aims to restore a swimmer’s muscle power and hence improvement of their swimming performance post-intervention. Aim The aim of this study was to determine the immediate effect of dry needling common myofascial trigger points (MFTP) found in four muscles of the shoulder girdle on competitive swimmers’ 100m freestyle lap-times. Methods The design was a pre-test post-test quasi-experimental study. Thirty five competitive swimmers between the ages of 16 and 30 years old participated in this study. Each participant underwent one assessment. Participants’ lap-times were taken using a Sportline Econosport Stopwatch. The pre- and post-intervention lap-times were compared to each other using statistical analysis. The intervention for the purpose of the study was trigger point dry needling. Myofascial trigger points were assessed using manual palpation and the Myofascial Diagnostic Scale (MDS). Results The median lap time was slightly longer post intervention (0:01:16.10) than pre-intervention (0:01:16.03), and was highly statistically significant (p=0.001). The results of the study were inconclusive, however, as there were too many confounding variables (for example, fatigue due to repeatedly swimming laps, swimmers of a lower caliber and hence quicker fatigue rate being included in the study)which negated the effect of dry needling and so the poorer performance of the participants post-intervention could not be attributed entirely to the intervention. A small number of participant’s lap-times decreased post-intervention i.e. they performed better post-intervention. These individualswere predominantly sprint-swimmers. Conclusion Dry needling negatively affects immediate lap-time performance. Future studies should reduce the number of variables affecting the study, for example, having a sprinter versus long-distance swimmer group, testing the outcome of dry needling after the swimmer has had sufficient time (for example, a day) to rest post-intervention.

    Prevalence and selected risk factors for neck, shoulder and low back pain among primary school teachers in the Central Durban area : a cross-sectional study
    (2016) Eggers, Lindy; Pillay, Julian David; Govender, Nalini
    Background: Musculoskeletal disorders (MSDs) are a significant and common occupational health concern, consequently impacting work attendance and performance. High prevalence rates of MSDs have been reported amongst school teachers. Studies have linked these higher prevalence rates to typical daily teaching activities including prolonged standing, awkward postures, heavy lifting, bending and repetitive movements. Objectives: To determine the prevalence of neck, shoulder and low back pain among primary school teachers in the Central Durban area; to identify any risk factors associated with neck, shoulder and low back pain; and to establish the relationship, if any, between the prevalence and risk factors of neck, shoulder and low back pain among primary school teachers. Methods: This was a quantitative, descriptive and cross-sectional study, conducted in 12 selected public primary schools within the Central Durban area. Volunteers who met the inclusion criteria (n = 97) were invited to complete self-administered questionnaires. Results: Of the 97 completed questionnaires 83.1 percent (%) reported neck and shoulder pain and 71.0% low back pain. Neck and shoulder pain were significantly associated with a forward-bent head posture (p = 0.001), ethnicity (p = 0.001), and history of a severe trauma/injury (p = 0.006). Similarly, significant associations were noted with regards to medical conditions (p = 0.006), a backward-bent head posture (p = 0.016), lifting of heavy loads (p = 0.045) and treatment for severe injury (p = 0.047). Associations were also noted between low back pain and prolonged standing (p = 0.000), ethnicity (p = 0.008), transportation methods (p = 0.023), medical conditions (p = 0.031) and a history of a severe trauma/injury (p = 0.049). Conclusion: This is a first South African study, to our knowledge that highlights increased prevalence rates for both neck and shoulder pain and low back pain amongst teachers, with a variety of associated risk factors. This draws attention to the urgent need for intervention programs to be implemented to prevent/reduce the development of musculoskeletal pain amongst teachers.

    The short term efficacy of thoracic spinal manipulation on shoulder impingement syndrome
    (2015) Booyens, Ryan Patrick; O'Connor, Laura
    Background: The most common shoulder complaint seen by physicians is shoulder impingement syndrome. There has been limited success with the current conservative treatment that has been provided for this condition. Thoracic spine and rib manipulation is purported to aid in the treatment of this condition; however there is a paucity of controlled investigations. The purpose of this study was to determine the short term efficacy of thoracic and prone rib manipulation on shoulder impingement syndrome. Methods: A randomised, placebo controlled pre-test post-test experimental design was used. Informed consent was obtained and 30 participants were recruited according to inclusion criteria and allocated to either a placebo or intervention group. Intervention consisted of thoracic spinal and rib manipulation. Data was collected, pre and post the first treatment and at a 48 hours follow up. SPSS was used to analyse the data with a p value of 0.05. Results: No statistically significant differences were seen between the groups for pain rating, range of motion of the glenohumeral joint, lateral scapula slide test or scapula isometric pinch test. The shoulder pain and disability index (SPADI) showed significant (p = 0.04) differences between the groups in terms of disability scores, with the intervention group having a great improvement in disability. No clinically significant differences were observed between the groups. Conclusion: Thoracic spine and rib manipulation appears to improve the disability associated with shoulder impingement syndrome, however further research is required with a larger sample size.

    The immediate effect of dry needling of the most tender active myofascial trigger point of the rotator cuff musculature on bowling speed in action cricket fast bowlers
    (2008) Subrayan, Darren; Docrat, Aadil
    Purpose Cricket fast bowlers are prone to the development of Myofascial pain syndrome and in particular active myofascial trigger points in their rotator cuff muscles of the shoulder joint (Scott, et al. 2001). This is due to the severe stresses placed upon the muscles, bones and joints of the shoulder as a result of the high velocity throwing action (Bartlett, et al.1996). In muscles containing active myofascial trigger points a decrease in the stretch range of motion as well as the maximal contractile force is noted, these two factors may negatively affect the speed at which a fast bowler deliver the ball (Travell, Simons and Simons, 1999). Dry needling is viewed as the most effective means of deactivating myofascial trigger points leading to in increase in both the contractile force and range of motion of the affected muscle, which could increase the speed at which the bowler delivers the ball (Wilks, 2003). The aim of the study was to determine the immediate effect of dry needling active myofascial trigger points of the rotator cuff on bowling speed in action cricket fast bowlers. Method The study consisted of 40 participants (randomly split into two equal groups of 20) each with shoulder pain of a myofascial origin. Group A (intervention group) received the dry needling intervention in their most tender active myofascial trigger point. While participants in Group B (control group) received no treatment. Bowling speeds were measured both before and after the intervention, to determine its effect on bowling speed. IV Data was entered into MS Exel spreadsheet and imported into SPSS version 15 (SPSS Inc.,Chicago, Iiiinois, USA), which was used for data analysis. Paticipants were evaluated on bowling speed, Algometer readings and Numerical pain rating Scale (NRS) both pre and post intervention. Participants were also asked if they believed the intervention increased, decreased or had no effect on their bowling speeds. Two sample t-test was used to compare baseline values between the groups. A repeated measure ANOVA was used to compare the rate of change of each outcome over time in the two groups. Pearson’s correlation analysis (intra-group) was used to assess the strength and magnitude of correlations of the changes in the outcomes. The McNemar – Bowker test and Weighted Cohen’s kappa statistics were calculated to assess agreement between perceived and actual levels of change. Results A significant treatment effect was observed in the intervention group were an increase in bowling speed, algometer readings as well a decrease in Numerical pain rating scale(NRS) scores was observed. There was also a perceived increase in the speed the participants delivered the ball in the intervention group. No significant changes were observed in the control group. The findings of this study indicate that dry needling as a treatment modality would be beneficial to fast bowlers in not only increasing their speeds but also the pain experienced as a result of active myofascial trigger points.
