The use of evidence-based practices for the management of shoulder impingement syndrome among Indian physical therapists: a cross-sectional survey

Prevalence of positive modified scapular assistance test in patients with shoulder pain with and without scapular dyskinesis: a cross-sectional study

BACKGROUND

Scapular dyskinesis (SD) is defined as an altered position of the scapula or altered motion patterns and their relationship with shoulder pain (SP) is still under debate. The modified scapular assistance test (mSAT) modifies scapular kinematics and is used to determine the impact of scapular dyskinesis in shoulder pain. However, data about the relationship between SD and the result of mSAT is scarce.

PURPOSE

The aim of this study is to establish the frequency of positive mSAT in patients with SP and compare the prevalence in those with and without SD. As a secondary objective, we compare changes in pain intensity during the mSAT in patients with a positive test between those with and without SD.

STUDY DESIGN

Cross-sectional study.

METHODS

Adult patients with a diagnosis of SP and with pain ≥2 during anterior flexion were included. The mSAT, scapular dyskinesis test (SDT), and shoulder function were assessed.

RESULTS

The study was conducted between August 2018 and May 2022 and included 70 patients. The prevalence of SDT was 54.29%. No statistically significant associations were detected when assessing the relation between the presence of mSAT and SDT (p-value 0.83). When comparing pain response during the mSAT in patients with a positive test, no differences were seen between patients with SD and patients without SD (p-value 0.26).

CONCLUSIONS

The prevalence of positive mSAT results was equal between individuals with and without SD. These findings suggest that the presence or absence of SD in individuals with SP was independent of the mSAT result. The mSAT should not be used solely for the assessment of SD in clinical practice nor be influenced by the SDT result. More research is needed to determine if the result of this test could inform prognosis and guide treatment choices.

Spinal Manipulation and Electrical Dry Needling in Patients With Subacromial Pain Syndrome: A Multicenter Randomized Clinical Trial

OBJECTIVES

To compare the effects of spinal thrust manipulation and electrical dry needling (TMEDN group) to those of nonthrust peripheral joint/soft tissue mobilization, exercise, and interferential current (NTMEX group) on pain and disability in patients with subacromial pain syndrome (SAPS).

DESIGN

Randomized, single-blinded, multicenter parallel-group trial.

METHODS

Patients with SAPS were randomized into the TMEDN group (n = 73) or the NTMEX group (n = 72). Primary outcomes included the Shoulder Pain and Disability Index and the numeric pain-rating scale. Secondary outcomes included the global rating of change scale (GROC) and medication intake. The treatment period was 6 weeks, with follow-ups at 2 weeks, 4 weeks, and 3 months.

RESULTS

At 3 months, the TMEDN group experienced greater reductions in shoulder pain and disability (P<.001) compared to the NTMEX group. Effect sizes were large in favor of the TMEDN group. At 3 months, a greater proportion of patients within the TMEDN group achieved a successful outcome (GROC score of 5 or greater) and stopped taking medication (P<.001).

CONCLUSION

Cervicothoracic and upper-rib thrust manipulation combined with electrical dry needling resulted in greater reductions in pain, disability, and medication intake than nonthrust peripheral joint/soft tissue mobilization, exercise, and interferential current in patients with SAPS. The effects were maintained at 3 months. J Orthop Sports Phys Ther 2021;51(2):72-81. Epub 28 Aug 2020. doi:10.2519/jospt.2021.9785.

Test-Retest Reliability of Handgrip Strength as an Outcome Measure in Patients With Symptoms of Shoulder Impingement Syndrome

OBJECTIVE

The purpose of this study was to investigate the degree of test-retest reliability of grip strength measurement using a hand dynamometer in patients with shoulder impingement syndrome.

METHODS

A total of 19 patients (10 women and 9 men; mean ± standard deviation age, 33.2 ± 12.9 years; range 18-59 years) with shoulder impingement syndrome were measured using a hand dynamometer by the same data collector in 2 different testing sessions with a 7-day interval. During each session, patients were encouraged to exert 3 maximal isometric contractions on the affected hand and the mean value of the 3 efforts (measured in kilogram-force [Kgf]) was used for data analysis. The intraclass correlation coefficient (ICC_2,1) as well as the standard error of measurement (SEM) and Bland-Altman plot were used to estimate the degree of test-retest reliability and the measurement error, respectively.

RESULTS

Grip strength data analysis revealed an ICC_2,1 score of 0.94, which, based on the Shrout classification, is considered as excellent test-retest reliability of grip strength measurement. The small values of SEMs reported in both sessions (SEM₁, 2.55 Kgf; SEM₂, 2.39 Kgf) and the small width of the 95% limits of agreement in the Bland-Altman plot (ranging from -7.39 Kgf to 7.03 Kgf) reflected the measurement precision and the narrow variation of the differences during the 2 testing sessions.

CONCLUSIONS

Results from this study identified excellent test-retest reliability of grip strength measurement in shoulder impingement syndrome, indicating its potential use as an outcome measure in clinical practice.

Do physical therapists follow evidence-based guidelines when managing musculoskeletal conditions? Systematic review

OBJECTIVES

Physicians often refer patients with musculoskeletal conditions to physical therapy. However, it is unclear to what extent physical therapists' treatment choices align with the evidence. The aim of this systematic review was to determine what percentage of physical therapy treatment choices for musculoskeletal conditions agree with management recommendations in evidence-based guidelines and systematic reviews.

DESIGN

Systematic review.

SETTING

We performed searches in Medline, Embase, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, Allied and Complementary Medicine, Scopus and Web of Science combining terms synonymous with 'practice patterns' and 'physical therapy' from the earliest record to April 2018.

PARTICIPANTS

Studies that quantified physical therapy treatment choices for musculoskeletal conditions through surveys of physical therapists, audits of clinical notes and other methods (eg, audits of billing codes, clinical observation) were eligible for inclusion.

PRIMARY AND SECONDARY OUTCOMES

Using medians and IQRs, we summarised the percentage of physical therapists who chose treatments that were recommended, not recommended and had no recommendation, and summarised the percentage of physical therapy treatments provided for various musculoskeletal conditions within the categories of recommended, not recommended and no recommendation. Results were stratified by condition and how treatment choices were assessed (surveys of physical therapists vs audits of clinical notes).

RESULTS

We included 94 studies. For musculoskeletal conditions, the median percentage of physical therapists who chose recommended treatments was 54% (n=23 studies; surveys completed by physical therapists) and the median percentage of patients that received recommended physical therapy-delivered treatments was 63% (n=8 studies; audits of clinical notes). For treatments not recommended, these percentages were 43% (n=37; surveys) and 27% (n=20; audits). For treatments with no recommendation, these percentages were 81% (n=37; surveys) and 45% (n=31; audits).

CONCLUSIONS

Many physical therapists seem not to follow evidence-based guidelines when managing musculoskeletal conditions. There is considerable scope to increase use of recommended treatments and reduce use of treatments that are not recommended.
