Brief Summary

The goal of this clinical trial is to test a digital treatment for patients with subacromial pain using the digital Shoulder Aid (diSAID) strategy. The participants in this study will be randomly assigned to digital treatment (diSAID) or to receive the treatment that is currently available in primary care, i.e. continue according to usual practice.

The main question this clinical trial aims to answer are:

- Can the diSAID improve shoulder function and reduce pain for patients with subacromial pain in primary care?

Detailed Description

Subacromial pain is the most common shoulder complaints in the general population. The pathology is multifactorial and mainly explained by pain generated from structures in the space between the caput humeri and acromion, especially the bursa and tendons of the rotator cuff. Exercises have positive effects on shoulder function, pain and satisfaction in patients with subacromial pain and is according to current evidence the primary treatment for this condition. Surgery and exercise have been shown to have an equivalent positive effect and it is possible to avoid surgery with specific training. This means that the motive for surgery has become increasingly questionable. Despite this, many patients undergo surgery without having taken part in specific supervised training and the selection of patient's prior to surgery is still inadequate. One reason for this may be that resources in healthcare are limited. Supervised training with physical visits over a longer period of time can be difficult for the primary care to offer. This require demands on physiotherapists' skills, time and resources.

Clinical studies with digital solutions are increasing and occur in several areas of healthcare. Digital interventions have proven to be effective in several diseases and disorders and can increase access to health education in a cost-effective way.

This is a single-blind, prospective, non-inferiority randomised controlled trial, designed to evaluate the feasibility and efficacy of a digital physiotherapy treatment compared to traditional physiotherapy for patients with subacromial pain in a primary care setting. The hypothesis is that clinical outcomes of the digital physiotherapy intervention for patients with subacromial pain can be effective and non-inferior compared to traditional physiotherapy in primary care.

Further the study objective is to evaluate the cost-effectiveness and impact on the environment using a digital intervention.

Sample size calculation: The estimated sample size is based the primary outcome SPADI assuming α = 0.05, β = 0.2 with a given power of 80% and a standard deviation of 18. A non-inferiority margin is set to 10 points (δ = -10) in total SPADI scores. Consequently, 82 patients have to be included, 41 per treatment group. Due to drop outs an over recruitment is planned (Total achievement of 60 per group).

We will use unpaired t-tests to compare the effect of treatment between the different groups regarding the primary outcome shoulder function and pain evaluated with SPADI after 3 months. The H0 hypothesis will be rejected and the H1 hypothesis will be accepted if a significant difference is proven. H0 is also rejected if non-inferiority of digital physiotherapy to traditional physiotherapy is proven. This is declared when the upper confidence limit of the one-sided confidence interval for the mean change of SPADI is lower than the selected non-inferiority margin (δ = -10).

(H0 : μA - μB ≤ -δ; H1 : μA - μB ≥ -δ).

Method:

Patients with subacromial pain are recruited from five different physiotherapy units in county of Region Östergötland, in Sweden. All patients receives an in-person evaluation performed by physiotherapists in primary care to ensure that potential participants meet the eligibility criteria. Participants available for recruitment due to study criteria's are assigned randomly to 1) Digital physiotherapy group 2) Traditional physiotherapy group. All participants will be followed-up after three months, six months and two years after the received intervention.

Arm && Interventions

Group	Intervention	Description
Traditional Physiotherapy	Traditional Physiotherapy	The traditional physiotherapy group receives current practice provided by physiotherapist in primary care with no predefined directives. The treating physiotherapist are instructed to treat their patient as they usually do.
Digital Physiotherapy (diSAID)	Digital Physiotherapy (diSAID)	The digital physiotherapy group receives the digital Shoulder Aid (diSAID) strategy available via a web application. For three months, this group will complete a home-based rehabilitation programme containing education and evidence based exercises for patients with subacromial pain tutored by videos, images and instructions.The treatment is standardized but can be customized by a responsible physiotherapist during the whole treatment period. The Physiotherapist also deliver progression in the education and in the exercises during the whole treatment period and can support the patient via a messenger function in the web application.

Primary Outcome Measures

Name	Time	Method
Mean change in shoulder function and pain after 12 weeks using The Shoulder Pain and Disability Index (SPADI)	Initial, 12 weeks, 6 months, 2 year	The Shoulder Pain and Disability Index has good psychometric properties with good reliability and validity. It consists of two sub-areas, the first area includes five questions for the estimation of pain and the second area includes eight questions about the impact on activity-related function of the upper extremity. Grading of pain or functional limitation goes from 0-10 where 0 indicates "no pain or disability" and 10 indicate "maximum pain or disability". The sub-areas generate individual scales as well as a common total score that is given as a percentage. Minimal Clinically Important Difference is 8 to 13 points and Minimal Detectible Change is 18 points.

Secondary Outcome Measures

Name	Time	Method
Mean change in shoulder pain intensity at rest, arm activity and at night measured by numeric rating scale (NRS)	Initial, 12 weeks, 6 months, 2 year	Pain level is rated between 0-10, where 0 corresponds to "no pain" and 10 corresponds to "worst pain imaginable".
Mean change in pain Self-Efficacy	Initial, 12 weeks, 6 months, 2 year	The Pain Self-Efficacy Questionnaire (PSEQ) is a 10-item questionnaire assessing peoples capabilities and the confidence in performing activities while ongoing pain. Each task have an answer that range from "not at all confident" to "completely confident" on a 7-point scale. The questions includes capacity of specific functional tasks and beliefs of handling function demands. Added scores from all items gives a total score, ranging from 0 to 60. Higher scores reflect stronger self-efficacy. The PSEQ have good psychometric properties of reliability, validity, and internal consistency
Mean change of self-reported rating of improvement	Initial, 12 weeks, 6 months, 2 year	Patient Global Impression of Change (PGIC) is a self-report measure reflecting a patient's improvement and belief about the efficacy of treatment between two time points. In this version the patients rate their change as "Completely recovered" "Much improved" "Slightly improved" "Unchanged" or "Worse".
Mean change of health-related quality of life	Initial, 12 weeks, 6 months, 2 year	EuroQol Instrument (EQ5D index and EQ VAS) is a self-reported measure capturing five dimensions of health-related quality of life: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The questions are validated and reliable for a broad spectra of medical conditions. The instrument can also be used as a measure in Estimation of health utility and quality-adjusted life years (QALYs) and is a part of the economic evaluation of the digital treatment.
