The purpose of the this survey study was twofold: 1) to examine different aspects of satisfaction with post-operative care in injured workers who have undergone rotator cuff surgery and 2) to examine the relationship between receiving a newly implemented summary report and the overall satisfaction with surgery and recovery.

The clinical communication summary report was given to injured workers following their review assessment to share with the family doctor or other health care providers. The form indicated a need for further assessments or investigations and return to work recommendations. The study involved using a satisfaction survey that examined different aspects of follow-up visit and workers’ opinion about their understanding of the nature of surgery, their progress, clinical management, and usefulness of the newly implemented summery report.

Eighty patients completed the questionnaire (mean age: 54 (8), 62(78%) males, of whom 26 (34%) had a rotator cuff decompression and 31 (40%) had a rotator cuff repair with 20 (26%) having both procedures and three missing data. There were no statistically significant relationships between the patient demographics (age, sex or type of surgery) and satisfaction. However, there was a significant correlation between how patients perceived the summary report in terms of helpfulness and the overall satisfaction with surgery (FTE<0.0004, p=0.001) and the satisfaction with recovery (FTE<0.0001, p=0.001). This may indicate that improvement in worker's understanding of their treatment recommendations and restrictions is associated with higher levels of overall satisfaction in this population.

Our results indicate a positive linear relationship between expressing a high satisfaction and the helpfulness of the summary report. As part of improving care, adding a summary report may facilitate sharing information with the injured workers, their care providers and their workplace.

Virtual physiotherapy has been provided to hundreds of patients at the Holland Centre during the COVID pandemic. As we plan for virtual care to be one part of our care delivery we want to evaluate it and ensure the care delivery is safe and effective.

The objectives of this project was two-fold: 1) to examine the outcome of virtual physiotherapy and/ or a hybrid of virtual and in-person care in patients who received post-operative treatment following total knee replacement at the Holland Centre, 2) to explore the challenges of virtual care participation in the joint replacement population.

Patients who received either virtual care or a combination of in-person and virtual care (hybrid model) based on the patients’ needs were included. Patient-related outcomes were the Patient Specific Functional Scale (PSFS) and pain scale. Flexion and extension range of motion were measured before and after treatment. A modified Primary Care Patient Experience Virtual Care Survey was used to examine barriers for virtual care.

Sixty patients, mean age 68(8), ranging between 45-83 years, 34(57%) females, who received either virtual care or a combination of in-person and virtual care based on the patients’ needs were included. Patients showed improvement in the PSFS and pain scores (p<0.0001). Flexion (p<0.0001) and extension (p=0.02) improved at a statistically significant level. A separate sample (N=54) (age range 50-85 years) completed the patient experience survey.

A well-designed post-operative virtual physiotherapy program, initially implemented to maintain continuity of care during the pandemic, continues to be an important part of our model of care as we normalize our activities. Clear understanding of barriers to virtual care and mitigation strategies will help us create virtual care standards, meet our patient needs, optimize our care delivery and potentially increase the use of virtual rehab in the future.

The Severity Scoring System (SSS) is a guide to interpreting findings across clinical, functional, and radiological findings, used by qualified, specially trained physiotherapists in the advanced practice role in order to provide consistency in determining the severity of the patient's condition and need for surgical consultation. The system has been utilized for over 14 years as a part of standardized assessment and management care and was incorporated into virtual care in 2020 following the pandemic restrictions. The present study examined the validity of the modified SSS in virtual care.

Patients who were referred to the Rapid Access Clinic (RAC), were contacted via phone by two experienced advanced practice practitioners (APPs) from May to July 2020, when in-person care was halted due to the pandemic. The virtual interview included taking history, completing self-reported measures for pain and functional ability and reviewing the radiological reports.

A total of 63 patients were interviewed (mean age 68, SD=9), 34 (54%) females. Of 63 patients, 33 (52%) were considered a candidate for total knee arthroplasty (TKA). Men and women were comparable in age, P4 and LEFS scores. The TKA candidates had a significantly higher SSS (p<0.0001) and pain scores (p=0.024). The variability of the total SSS score explained by the functional, clinical and radiological components of the tool were 55%, 48% and 4% respectively, highlighting the more important role of patient's clinical history and disability in the total SSS.

The virtual SSS is a valid tool in directing patients for surgical management when used by highly trained advanced practice physiotherapists. A large component of the SSS is based on clinical data and patient disability and the APP's skillset rather than severity of pathology found on imaging.

The primary purpose of this longitudinal study was to examine the impact of physical and mental well-being on a successful return to work after cartilage or ligament knee injury. A secondary purpose was to examine the effectiveness of our program regarding ordering imaging (plain X-rays, US, MRI, CT scan), and the impact that costly investigations made in clinical management.

Workers who had sustained a work-related knee injury and were assessed at the lower extremity specialty clinic of our hospital program were followed up until they were discharged. All patients completed the numeric pain rating scale (NPRS), the Lower Extremity Functional Scale (LEFS), and the Hospital Anxiety and Depression Scale (HADS) on the initial assessment and at final follow-up.

We included 30 patients, mean age, 50(9), 11(37%) females, 19(63%) males. The most common mechanisms of injury were twisting (13, 45%) and falls (12, 41%). The knee injuries included 10 anterior collateral ligament (ACL), 3 posterior collateral ligament (PCL), 19 medical and lateral ligament injuries, and 22 meniscus injuries with some injuries overlapping. Ten patients (30%) underwent surgery (8 meniscectomy, two ligamentous repairs).

Patients showed improvement in pain scores (p<0.0001) and the LEFS scores (p=0.004). Seventeen patients (57%) returned to full-time work and 11 (37%) were not working at the time of discharge with one patient performing part-time work, and one on re-training. Higher levels of pre (p=0.02) and post-treatment (p=0.03) depression and post-treatment anxiety (p=0.02) had a negative impact on a successful return to work. Most clients had proper investigations ordered by their family physicians in the community (24 plain x-rays, 11 US, and 21 MRI). Our team ordered only 6 plain x-rays and 6 new MRI.

We found significant improvement in pain and disability in injured workers who received an expedited multidisciplinary care. Anxiety and depression were the most important predictors of poorer recovery and a less successful work status. The judicious use of costly imaging is expected to reduce the overall health care cost of an injury, while providing new important information such as adding a new diagnosis or changing the management.

Physiotherapy is a critical element in successful conservative management of low back pain (LBP). The aim of this study was to develop and evaluate a system with wearable inertial sensors to objectively detect sitting postures and performance of unsupervised exercises containing movement in multiple planes (flexion, extension, rotation).

A set of 8 inertial sensors were placed on 19 healthy adult subjects. Data was acquired as they performed 7 McKenzie low-back exercises and 3 sitting posture positions. This data was used to train two models (Random Forest (RF) and XGBoost (XGB)) using engineered time series features. In addition, a convolutional neural network (CNN) was trained directly on the time series data. A feature importance analysis was performed to identify sensor locations and channels that contributed most to the models. Finally, a subset of sensor locations and channels was included in a hyperparameter grid search to identify the optimal sensor configuration and the best performing algorithm(s) for exercise classification. Models were evaluated using F1-score in a 10-fold cross validation approach.

The optimal hardware configuration was identified as a 3-sensor setup using lower back, left thigh, and right ankle sensors with acceleration, gyroscope, and magnetometer channels. The XBG model achieved the highest exercise (F1=0.94±0.03) and posture (F1=0.90±0.11) classification scores. The CNN achieved similar results with the same sensor locations, using only the accelerometer and gyroscope channels for exercise classification (F1=0.94±0.02) and the accelerometer channel alone for posture classification (F1=0.91±0.03).

This study demonstrates the potential of a 3-sensor lower body wearable solution (e.g. smart pants) that can identify proper sitting postures and exercises in multiple planes, suitable for low back pain. This technology has the potential to improve the effectiveness of LBP rehabilitation by facilitating quantitative feedback, early problem diagnosis, and possible remote monitoring.

Summary

Data of 663 patients with three different pathologies were examined. We found that using patients with significant symptoms and functional difficulty in the opposite shoulder will not bias the results of observational studies if outcomes are based on routine disability measures such as ASES or Constant-Murley scores.

Summary

Analysis of existing data of patients who had undergone debridement procedure for osteoarthritis (OA) of glenohumeral joint showed improvement in disability at a minimum of one year following surgery. Injured workers were significantly younger and had a poorer outcome.

Summary

In the sample studied, reparability of large and massive tears was associated with pre-op ASES and active external rotation in neutral position. Surgical factors affecting reparability were tear size, tendon mobility and shape of the tear.
