Laser-Pointer assisted angle reproduction test (LP-ART): reliability, performance, and correlation with shoulder pain and disability in patients with subacromial pain syndrome

INTRODUCTION

The proprioception plays an important role in the stability of the shoulder joint. However, clinical practice lacks reliable and user-friendly tools.

OBJECTIVES

To evaluate the intra- and inter-rater reliability of the Laser-Pointer assisted Angle Reproduction Test (LP-ART), to analyze the difference in proprioception between the symptomatic and asymptomatic shoulders, and to investigate if there is a correlation between the LP-ART and the pain intensity assessed by 11-point Numerical Rating Pain Scale (NRPS) and the level of shoulder disability and pain assessed by the Disability Index and Shoulder Pain (SPADI - BR).

METHODS

Fifty patients (age = 56.2 ± 10.4 years) performed the LP-ART at 90° of shoulder flexion.

RESULTS

The intra and interrater reliability of the LP-ART measurements was moderate (Intraclass Correlation Coefficient_2,3 = 0.41 to 0.65) for both shoulders, symptomatic and asymptomatic. There was no difference in the absolute angular deviation between shoulders (mean difference of 0.4°, P = .581). The absolute angular deviation was not significantly correlated with the pain intensity (rs = 0.007, P = .962) and the SPADI - BR (r_s = 0.022, P = .881).

CONCLUSION

The LP-ART measurement showed moderate reliability in participants with subacromial pain syndrome. The active joint position sense was not different between symptomatic and asymptomatic shoulders, and there was no correlation between proprioception and the pain intensity and shoulder pain and disability level.

Effects on shoulder pain and disability of teaching patients with shoulder pain a home-based exercise program: a randomized controlled trial

Objective:

To investigate the effect on shoulder pain and disability of teaching patients with shoulder pain how to undertake a home-based exercise program.

Design:

A randomized controlled trial conducted from September 2015 to January 2016.

Setting:

Participants’ home.

Participants:

Sixty participants with shoulder pain who were waiting for physiotherapeutic treatment.

Interventions:

The control group ( n = 30) received minimal education about their shoulder condition and instructions to continue their activities as normal. The intervention group ( n = 30) received a two-month home exercise program with one-hour sessions delivered by a physiotherapist to begin and one month after the program for exercise instructions.

Main measures:

The primary outcome was change in the Shoulder Pain and Disability Index (SPADI). The secondary outcomes included change in the numeric pain rating scale and medication intake for pain relief.

Results:

The patients’ average age was 54.3 (13.8) years. SPADI scores at baseline were 60.9 (16.5) in the intervention and 64.7 (15.3) in the control group. After two months, the SPADI scores decreased to 18.8 (28.6) and to 61.4 (24.0), respectively, in the intervention and control groups with an estimated mean difference of 40.0, effect size: 1.61. The intervention group showed a reduced pain intensity (estimated mean difference: 3.7, effect size: 2.43) and medication intake (chi-square: 0.001). The number needed to treat was 1.2 for one patient to have a SPADI score <20.

Conclusion:

Teaching patients with shoulder pain how to undertake a home-based exercise program improved shoulder function and reduced pain intensity and medication intake over two months.
