    The efficacy of shoulder adjustments on patients suffering from shoulder impingement syndrome
    (1999) Munday, Sarah Louisa; Jones, Andrew D.
    Impingement syndrome of the shoulder is a very common problem, yet the diagnosis and management of it is still not completely understood. The purpose of this investigation was to investigate the effectiveness of the chiropractic adjustment in order to determine whether or not it is an effective approach in the treatment of impingement syndrome

    The efficacy of shoulder adjustments in the treatment of rotator cuff tendinitis
    (2002) Azizi, Maryam; Mathews, Robert
    Purpose . Rotator cuff tendinitis is a common problem, however, its diagnosis and management is not completely understood. The purpose of this research project was to investigate the efficacy of the chiropractic adjustment to determine whether or not it is an effective approach in the treatment of rotator cuff tendinitis. Methods This randomized controlled trial consisted of two groups. Each group consisted of thirty subjects, of any age, selected from the general population and randomly allocated to Group 1 or 2, participation in this trial was voluntary. Group 1 received chiropractic adjustment of the glenohumeral or acromioclavicular joint according to the fixations found on motion palpation and group 2 received placebo laser. Subjects in both groups had to comply with certain inclusion criteria before being allowed to participate in the study. Goniometer readings were taken to measure range of motion, algometer readings to measure pain threshold and the Numerical Pain Rating Scale was answered at the initial consultation, and on the third and sixth consultations. The Unpaired and Friedman's T- tests were used to assess the intra and intergroup information from the first, third and sixth consultations. Groups 1 and 2 were compared in terms of age, gender, race and clinical severity prior to onset.

    The effect of a single versus multiple cervical spine manipulations on peak torque of the rotator cuff muscles in asymptomatic subjects with cervical spine fixation
    (2009) Blakeney, Carmen; Wilson, Laura Maie; Korporaal, Charmaine Maria
    Aim: The aim of the study was to assess the effect of a single versus multiple cervical spine manipulations, over a two week period, on peak torque of the rotator cuff muscles utilizing the Cybex Orthotron II Isokinetic Rehabilitation System. This study was a pre and post experimental investigation. Method: Forty asymptomatic (in terms of neck and shoulder pain) male chiropractic students were stratified into two equal groups of twenty subjects to ensure that each group consisted of an equal number of subjects from each year of study. All subjects underwent a familiarisation session on the Cybex Orthotron II Isokinetic Rehabilitation System. Group One received a single manipulation. Rotator cuff peak torque was measured pre-manipulation, immediately post manipulation and at a two-week follow up. Group Two received four manipulations over a two week period. Rotator cuff peak torque was measured pre and immediately post the first manipulation. A third rotator cuff peak torque measurement was taken two weeks after the first manipulation. Results: There was no statistically significant effect of a single or multiple manipulations on rotator cuff peak torque (abduction, adduction, internal rotation and external rotation). Inter-group analysis revealed a trend of an effect for abduction as the single manipulation increased at the two-week follow up and the multiple manipulation group decreased; however, this was not statistically significant. Conclusion: No statistically significant results were found possibly due to small sample size and the fact that objective measurements were only taken at the beginning and the end of the research processes and not at regular intervals throughout the study.Further studies are needed to determine the effects of multiple manipulations on peripheral muscle activity, including the treatment of symptomatic patients with rotator cuff pathology. It is also recommended that EMG readings be done in conjunction with peak torque measures to determine muscle activity.

    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.

    The immediate effect of manipulation of selected cervical spinal segments on the peak torque of the rotator cuff muscles in asymptomatic patients with and without a mechanical cervical spine dysfunction
    (2005) Dixon, Tamsyn Louise; Korporaal, Charmaine Maria
    Although studies of manipulation-induced peripheral changes in the muscles have been done, inconsistencies noted by the author’s call for further investigation into the reflex effects of manipulation. Additionally, according to the literature, no effective treatment protocol for the painful shoulder has been found. Therefore this research aimed at addressing these discrepancies by quantifying the immediate effect of cervical spine manipulation in terms of peak torque on rotator cuff musculature in asymptomatic patients with both a cervical spine dysfunction and without. And thus by investigating cervical manipulation to the C4-C7 spinal segment, as a possible added intervention for improving rotator cuff muscle peak torque, a more efficient and effective management protocol for the painful shoulder could be attained. Thus the aims for this study included: 1) To evaluate whether manipulation has an effect on rotator cuff peak torque or not, utilizing the Cybex Orthotron II Isokinetic Rehabilitation System; 2) To ascertain whether manipulation of the specific levels has an effect on the rotator cuff peak torque or not and 3) To ascertain whether the presence or absence
