Assessing the patient-specific functional scale's ability to detect early recovery following total knee arthroplasty

Factors associated with patient-reported mouth opening activity limitations in individuals with persistent intra-articular temporomandibular disorders: A cross-sectional study exploring physical and self-reported outcomes

BACKGROUND

Individuals living with intra-articular temporomandibular disorders (IA-TMDs) often report limitations with mouth opening activities. While clinical measures such as active range of motion (AROM) and movement quality are often used to assess mouth opening function, it is unclear if and how these relate to patient-reported limitations and whether other factors such as kinesiophobia influence mouth opening activities in those with IA-TMDs.

OBJECTIVES

Compare clinical measures of mouth opening function in those with IA-TMDs to asymptomatic controls. In those with an IA/TMD, explore relationships between patient-reported mouth opening limitations, and mouth opening function and kinesiophobia.

DESIGN

Cross-sectional study.

METHOD

Clinical mouth opening function (AROM, movement quality, pain on movement/10, stiffness on movement/10) was compared between groups (n = 30 IA-TMD, n = 30 controls). Within the IA-TMD group, correlations between patient-reported mouth opening limitations (Patient specific functional scale), kinesiophobia (Tampa Scale for Kinesiophobia for Temporomandibular Disorders) and clinical measures of mouth opening function were explored.

RESULTS

Impairments in AROM (-4 mm, p = 0.04, d = 0.5), movement quality (p < 0.01, φ = 0.6), pain on movement (p < 0.01, d = 0.8) and stiffness on movement (p < 0.01, d = 1.6) were observed in the IA-TMD group compared to controls. Patient-reported mouth opening limitations and kinesiophobia were significantly correlated (r = -0.48, p < 0.01); no correlation was found between patient-reported limitations and clinical mouth opening measures (r < 0.3, p > 0.05).

CONCLUSIONS

Mouth opening function is impaired in IA-TMD. However, kinesiophobia appears more related to patient-reported mouth opening limitations than clinical impairments. Consideration of clinical, kinesiophobia and patient-reported limitation measures are necessary to direct management of IA-TMD in those presenting for care.

Feasibility of a self-management intervention to improve mobility in the community after stroke (SIMS): A mixed-methods pilot study

OBJECTIVE

To evaluate the feasibility of implementing a self-management intervention to improve mobility in the community for stroke survivors.

METHODS

A two-phase sequential mixed methods design was used (a pilot randomised controlled trial and focus groups). Participants were adult stroke survivors within six months post discharge from hospital with functional and cognitive capacity for self-management. The intervention included education sessions, goal setting and action planning, group sessions, self-monitoring and follow up. The control group received usual care and both groups enrolled for 3 months in the study. Feasibility outcomes (recruitment and retention rates, randomisation and blinding, adherence to the intervention, collection of outcome measures, and the fidelity and acceptability of the intervention). Participants assessed at baseline, 3 months and 6 months for functional mobility and walking, self-efficacy, goal attainment, cognitive ability, and general health. A descriptive analysis was done for quantitative data and content analysis for the qualitative data. Findings of quantitative and qualitative data were integrated to present the final results of the study.

RESULTS

Twenty-four participants were recruited and randomised into two groups (12 each). It was feasible to recruit from hospital and community and to deliver the intervention remotely. Randomisation and blinding were successful. Participants were retained (83%) at 3 months and (79.2%) at 6 months assessments. Adherence to the intervention varied due to multiple factors. Focus groups discussed participants' motivations for joining the programme, their perspectives on the intervention (fidelity and acceptability) and methodology, perceived improvements in mobility, facilitators and challenges for self-management, and suggestions for improvement.

CONCLUSION

The self-management intervention seems feasible for implementation for stroke survivors in the community. Participants appreciated the support provided and perceived improvement in their mobility. The study was not powered enough to draw a conclusion about the efficacy of the program and a future full-scale study is warranted.

Addressing Chronic Conditions and Social Determinants of Health During the COVID-19 Pandemic

Chronic conditions or diseases are defined as persistent conditions lasting ≥ 1 year requiring either ongoing medical attention or limiting daily living or both (Agency for Healthcare Research and Quality (AHRQ) in Programs: SHARE approach workshop, Agency for Healthcare Research and Quality (AHRQ) (2016) Programs: SHARE approach workshop 2016. https://www.ahrq.gov/professionals/education/curriculum-tools/shareddecisionmaking/workshop/index.html . Accessed 20 Jan 2017). Physical chronic conditions, including diabetes, hypertension, heart disease, arthritis, and stroke, are prevalent, especially in the older population. Over 90% of older adults have at least 1 and 77% have ≥ 2 chronic conditions (American Diabetes Association (ADA) in Statistics about diabetes, American Diabetes Association (ADA) (2023) Statistics about diabetes. https://diabetes.org/about-us/statistics/about-diabetes . Accessed 20 Apr 2023). Chronic conditions account for $4.1 trillion of the nation's annual healthcare expenditure (Centers for Disease Control and Prevention, National Center for Chronic Disease Prevention and Health Promotion in Health and economic costs of chronic conditions, Centers for Disease Control and Prevention, National Center for Chronic Disease Prevention and Health Promotion. Health and Economic Costs of Chronic Conditions (2022). https://www.cdc.gov/chronicdisease/about/costs/index.htm . Accessed 7 Jan 2023). There are marked disparities based on age, color, and income, with older people, people of color, and lower-income people having higher treatment costs or even lost wages in response to having chronic conditions. Chronic conditions are the on-the-top leading causes for death with diabetes being the top 7th in the USA in 2019 (Ferguson in Metabolic Syndrome Related Dis, Ferguson et al., Metab Syndr Relat Disord 21:177-187, 2023).

Measurement Properties of the Patient-Specific Functional Scale and Its Current Uses: An Updated Systematic Review of 57 Studies Using COSMIN Guidelines

OBJECTIVE

To systematically review measurement properties, including acceptability, feasibility, and interpretability, and current uses of the Patient-Specific Functional Scale (PSFS).

DESIGN

Systematic review of a patient-reported outcome measure using the COnsensus-based Standards for the selection of health status Measurement INstruments (COSMIN) guidelines.

LITERATURE SEARCH

We searched 11 databases from January 2010 to July 2020 for articles on measurement properties or use of PSFS.

STUDY SELECTION CRITERIA

Published primary articles without language restrictions.

DATA SYNTHESIS

Two independent reviewers screened all records, extracted data, and performed risk of bias assessments using COSMIN guidelines. We qualitatively synthesized findings for each measurement property in musculoskeletal and nonmusculoskeletal conditions, and 2 reviewers independently performed Grading of Recommendations Assessment, Development and Evaluation assessments. This study was preregistered with the Open Science Framework (https://doi.org/10.17605/OSF.IO/42UZT).

RESULTS

Of the 985 articles screened, we included 57 articles on measurement properties and 255 articles on the use of PSFS. The PSFS had sufficient test-retest reliability in musculoskeletal (22 studies, 845 participants, low-to-moderate certainty) and nonmusculoskeletal conditions (6 studies, 197 participants, very low certainty), insufficient construct validity as a measure of physical function (21 studies, 2 945 participants, low-to-moderate certainty), and sufficient responsiveness (32 studies, 13 770 participants, moderate-to-high certainty). The standard error of measurement ranged from 0.35 to 1.5. The PSFS was used in 87 unique health conditions, some without prior evidence of validity.

CONCLUSION

The PSFS is an easy-to-use, reliable, and responsive scale in numerous musculoskeletal conditions, but the construct validity of PSFS remains uncertain. Further study of the measurement properties of the PSFS in nonmusculoskeletal conditions is necessary before clinical use. J Orthop Sports Phys Ther 2022;52(5):262-275.

A framework to make PROMs relevant to patients: qualitative study of communication preferences of PROMs

PURPOSE

Patient-reported outcome measures are tools for evaluating symptoms, magnitude of limitations, baseline health status, and outcomes from the patient's perspective. Healthcare professional organizations and payers increasingly recommend PROMs for clinical care, but there lacks guidance regarding effective communication of PROMs with orthopedic surgery patients. This qualitative study aimed to identify (1) patient attitudes toward the use and communication of PROMs, and (2) what patients feel are the most relevant or important aspects of PROM results to discuss with their physicians.

METHODS

Participants were recruited from a multispeciality orthopedic clinic. Three PROMs: the EuroQol-5 Dimension, the Patient-Specific Functional Scale, and the Patient-Reported Outcome Measurement Information System Physical Function Computer Adaptive Test were shown and a semi-structured interview was conducted to elicit PROMs attitudes and preferences. Interviews were transcribed and inductive-deductively coded. Coded excerpts were aggregated to (1) identify major themes and (2) analyze how themes interacted.

RESULT

Three themes emerged: (1) Beliefs toward the purpose of PROMs, (2) PROMs as a reflection of self, and (3) PROMs to facilitate communication and guide healthcare decisions. These themes informed a framework outlining the patient perspective on communicating PROMs during clinical care.

CONCLUSION

Patient attitudes toward the use and communication of PROMs start with the incorporation of patient beliefs, which can facilitate or act as a barrier to engagement. Patients should ideally believe that PROMs are an accurate reflection of personal health state before incorporation into care. Clinicians should endeavor to communicate the purpose of a chosen PROM in line with a patient's unique needs and what they feel is most relevant to their own care. Aspects of PROMs results which may be helpful to address include providing context for what scores mean and how they are calculated, and using scores as a way to weigh risks and benefits of treatment and tracking progress over time. Future research can focus on the effect of communication strategies on patient outcomes and engagement in care.

A digital decision support system (selfBACK) for improved self-management of low back pain: a pilot study with 6-week follow-up

Background

Very few of the publicly available apps directed towards self-management of low back pain (LBP) have been rigorously tested and their theoretical underpinnings seldom described. The selfBACK app was developed in collaboration with end-users and clinicians and its content is supported by best evidence on self-management of LBP. The objectives of this pilot study were to investigate the basis for recruitment and screening procedures for the subsequent randomized controlled trial (RCT), to test the inclusion process in relation to questionnaires and app installation, and finally to investigate the change in primary outcome over time.

Methods

This single-armed pilot study enrolled 51 participants who had sought help for LBP of any duration from primary care (physiotherapy, chiropractic, or general practice) within the past 8 weeks. Participants were screened for eligibility using the PROMIS-Physical-Function-4a questionnaire. Participants were asked to use the selfBACK app for 6 weeks. The app provided weekly tailored self-management plans targeting physical activity, strength and flexibility exercises, and education. The construction of the self-management plans was achieved using case-based reasoning (CBR) methodology to capture and reuse information from previous successful cases. Participants completed the primary outcome pain-related disability (Roland-Morris Disability Questionnaire [RMDQ]) at baseline and 6-week follow-up along with a range of secondary outcomes. Metrics of app use were collected throughout the intervention period.

Results

Follow-up data at 6 weeks was obtained for 43 participants. The recruitment procedures were feasible, and the number needed to screen was acceptable (i.e., 1.6:1). The screening questionnaire was altered during the pilot study. The inclusion process, answering questionnaires and app installation, were feasible. The primary outcome (RMDQ) improved from 8.6 (SD 5.1) at baseline to 5.9 (SD 4.0) at 6-week follow-up (change score 1.8, 95% CI 0.7 to 2.9). Participants spent on average 134 min (range 0–889 min) using the app during the 6-week period.

Conclusion

The recruitment, screening, and inclusion procedures were feasible for the subsequent RCT with a small adjustment. The improvement on the RMDQ from baseline to follow-up was small. Time pattern of app usage varied considerably between the participants.

Listening to Patients' Voices: Workarounds Patients Use to Construct Pain Intensity Ratings

This study analyzed patients' perspectives about a measure of current, usual, and extreme pain and a measure of activity-related pain. Thirty-one patients with osteoarthritis participated in focus groups. Researchers completed thematic analysis of transcripts using coding software and an inductive approach. Three emerging themes were that many factors affected patients' perceptions and ratings of pain intensity, patients used different approaches to construct pain ratings, and patients interpreted maximal response anchors differently. Particularly, novel findings were that patients evaluated pain fluctuation, location, duration, and quality when constructing pain intensity ratings. Also, activity items helped patients to remember pain and provided a valued context for communicating pain experiences. However, the activities needed to be sufficiently described and personally relevant. These findings further clarify the challenges patients face and the workarounds they use when rating pain intensity. The patients' suggestions for improved administration methods and items warrant future investigation.

The Group Experience: Remodelling Outpatient Physiotherapy after Knee Replacement Surgery

Purpose : To estimate responses to short-duration (4-6 weeks) group-based physiotherapy after knee replacement in terms of pain, function, and satisfaction.

METHOD

The study used a prospective, observational design. A total of 169 participants (111 women, 58 men) were consecutively recruited to attend a twice-weekly post-operative knee replacement class focused on mobility, strength, balance, and functional retraining. Changes in pain, function, and satisfaction were measured using the P4 pain intensity measure, the Lower Extremity Functional Scale (LEFS), a timed stair test (TST), knee range of motion (ROM), the Patient Specific Functional Scale (PSFS), and the Client Satisfaction Questionnaire (CSQ-8). Using Stata version 12.1, the data were summarized descriptively, and change scores were calculated with 95% CIs. Results : On average, participants were discharged within 11 classes, having achieved their treatment goals. More than 77% exceeded the minimal detectable change at the 90% confidence level (MDC90) on the LEFS, TST, PSFS, and ROM assessments. The mean CSQ-8 score at discharge was 31.8 (SD 1.46); 66.7% recorded a perfect score of 32. Conclusions : Patients attending a short group-based outpatient knee replacement class demonstrated significant improvements in pain and lower extremity function and were highly satisfied with their physiotherapy treatment.

The Patient-Specific Functional Scale: Its Reliability and Responsiveness in Patients Undergoing a Total Knee Arthroplasty

STUDY DESIGN

A prospective cohort study, with assessments before, at 3 months after, and at 12 months after total knee arthroplasty (TKA).

OBJECTIVES

To determine and compare the responsiveness and reliability of the Patient-Specific Functional Scale (PSFS) in patients undergoing a TKA.

BACKGROUND

Reliable and valid measurement instruments are important to measure functional status. The PSFS is frequently used in several patient populations, but its methodological characteristics in a population of patients with TKA in the perioperative phases of surgery are unknown.

METHODS

The PSFS, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and global perceived effect (GPE) were administered at 3 time points in 150 patients undergoing a TKA. Correlations, effect sizes, and standardized response means were calculated. The PSFS was administered twice to assess its reliability in terms of intraclass correlation coefficients and limits of agreement.

RESULTS

The correlation coefficients between the PSFS and WOMAC at 3 months and 1 year were 0.41 and 0.48, respectively; those between the PSFS and GPE were -0.37 and -0.55, respectively. The effect sizes of the PSFS at 3 months and 1 year were 1.71 and 2.89, respectively; those of the WOMAC were 1.45 and 1.64, respectively. The standardized response means of the PSFS at 3 months and 1 year were 0.96 and 1.48, respectively; those of the WOMAC were 1.28 and 1.37, respectively. The intraclass correlation coefficients ranged between 0.73 and 0.86. The systematic error was between 0.12 and 0.54. The limits of agreement ranged from ±2.17 to ±2.72.

CONCLUSION

The reliability of the PSFS is good. Its responsiveness is high, especially in the long term. However, the PSFS cannot be used interchangeably with the WOMAC in the immediate postoperative period.
