“…The HHD has good concurrent validity to a stationary isokinetic dynamometer (r = 0.81), 54 and has excellent inter/intra examiner reliability for shoulder external (lateral) rotation (ICC = 0.96/0.96) and abduction (ICC = 0.92/0.92). 55 The evaluation was standardized and followed the protocols developed and validated by Hébert. 56 Data Analysis Descriptive statistics were used for all outcome measures at each measurement time.…”

Introduction: Shoulder pain, a leading reason to consult a physician or physiotherapist, continues to be a challenge to rehabilitate, particularly with a military population. A rotator cuff (RC) tendinopathy, the most important source of shoulder pain, is one of the leading reasons for sick leave or a discharge from active military service. Research encourages the use of exercise prescription for the management of a RC tendinopathy, however the ideal method of delivery (group setting versus one-on-one) remains uncertain. The purpose of this single-blind (evaluator) pilot randomized clinical trial was to compare two 6-week rehabilitation programs, a newly developed groupsupervised neuromuscular training program and usual one-on-one physiotherapy care, on the pain and symptoms of Canadian soldiers affected by a RC tendinopathy. Materials and Methods: Thirty-one soldiers with the Canadian Armed Forces were randomly assigned to (1) a group-supervised neuromuscular training program (UPEx-NTP) or; (2) one-on-one usual physiotherapy care (UPC). The primary outcome was the Disability of Arm, Hand and Shoulder (DASH) questionnaire. Secondary outcomes included the Western Ontario Rotator Cuff (WORC) Index, pain levels at rest, and maximum isometric voluntary contractions (MIVC) of the abductors and external (lateral) rotators of the affected shoulder. Both were assessed at baseline (T 0 ), 6 (T 6 ) and 12 (T 12 ) weeks. Analysis included two-way repeated measures of variance for intention-to-treat (ITT) and per-protocol analyses. Results: Eighty military members with a RC tendinopathy were contacted, resulting in 31 participants who were randomized for their active intervention, in the UPEx-NTP or UPC, respectively. No significant group (p ≥ 0.16) or group × time interactions (p ≥ 0.11) were found for either ITT or per-protocol analyses. A statistically significant time effect (p < 0.001) was established for the DASH and WORC, showing that both groups improved over time. Conclusions: Our preliminary data demonstrates that both rehabilitation approaches, grounded in active exercises, were not statistically different from each other, and derived similar benefits over time for a military population. This suggests that a group intervention for a RC tendinopathy has potential to be just as effective as a one-on-one approach for a military population, an interesting avenue for an active working population. Larger sample sizes and further investigation are warranted regarding the cost and clinical resource benefits of a supervised group approach.

“…Nagatomi et al. 22 administered manual muscle tests to a group of patients already diagnosed with either a rotator cuff tear, superior labrum anterior-to-posterior lesion, or a Bankart lesion and found that patients with less than 60% of the uninvolved side strength were diagnosed as positive for a muscle tear, while none with equal strength to the contralateral side were positive. These authors also reported that there was a mixture of positive and negative findings among patients with 60–99% of the contralateral muscle strength.…”

“…This highlights the limited capability of manual muscle testing to detect changes in shoulder abduction strength. In a previous study, Nagatomi et al [33] obtained a 94.3% diagnostic accuracy in detecting a change in shoulder abduction strength for a 21.1% cut-off point difference when the contralateral side was considered. However, different shoulder pathologies from that of the present study were also analyzed.…”

“…However, different shoulder pathologies from that of the present study were also analyzed. Nagatomi et al [33] also tested both upper limbs simultaneously. Assessing the strength from both upper limbs at the same time might be more accurate than evaluating it over two different moments.…”

The Scapula Reposition Test (SRT) is proposed to determine if a relationship exists between scapular dyskinesis and shoulder pathology. The purpose of this study was to evaluate intra-rater and inter-rater reliability of the SRT in subjects with rotator cuff tendinopathy and scapular dyskinesis. In addition, we compared subjective strength findings from the test to an objective measure made by dynamometry. The SRT was independently and randomly performed by two physical therapists in 42 subjects. The percent agreement, Cohen's kappa (κ), maximum attainable κ, prevalence and bias indexes, and prevalence-adjusted-bias-adjusted kappa were used as intra-and inter-rater reliability estimates. Finally, the point-biserial correlation coefficient (r pb ) was used for correlation analysis of objective and subjective strength findings. A moderate intra-rater (κ = 0.43; CI 95%, 0.14 to 0.73; p = 0.004) and poor inter-rater (κ = 0.08; CI 95%, −0.22 to 0.38; p = 0.61) agreement was found. Subjective strength changes during SRT and dynamometry were poorly correlated (r pb = 0.137; CI 95%, −0.175 to 0.423; p = 0.389). The SRT cannot be recommended for clinical practice. More studies evaluating its reliability are needed as well as further research on the capability of a rater to manually detect strength changes.
