Agreement and concurrent validity between telehealth and in-person diagnosis of musculoskeletal conditions: a systematic review

OBJECTIVES

To assess the concurrent validity and inter-rater agreement of the diagnosis of musculoskeletal (MSK) conditions using synchronous telehealth compared to standard in-person clinical diagnosis.

METHODS

We searched five electronic databases for cross-sectional studies published in English in peer-reviewed journals from inception to 28 September 2023. We included studies of participants presenting to a healthcare provider with an undiagnosed MSK complaint. Eligible studies were critically appraised using the QUADAS-2 and QAREL criteria. Studies rated as overall low risk of bias were synthesized descriptively following best-evidence synthesis principles.

RESULTS

We retrieved 6835 records and 16 full-text articles. Nine studies and 321 patients were included. Participants had MSK conditions involving the shoulder, elbow, low back, knee, lower limb, ankle, and multiple conditions. Comparing telehealth versus in-person clinical assessments, inter-rater agreement ranged from 40.7% agreement for people with shoulder pain to 100% agreement for people with lower limb MSK disorders. Concurrent validity ranged from 36% agreement for people with elbow pain to 95.1% agreement for people with lower limb MSK conditions.

DISCUSSION

In cases when access to in-person care is constrained, our study implies that telehealth might be a feasible approach for the diagnosis of MSK conditions. These conclusions are based on small cross-sectional studies carried out by similar research teams with similar participant demographics. Additional research is required to improve the diagnostic precision of telehealth evaluations across a larger range of patient groups, MSK conditions, and diagnostic accuracy statistics.

Effect of foot health-related quality of life in rural population: A case-control study

BACKGROUND

Foot health problems can affect quality of life and general health producing a source of discomfort and pain. Low levels of foot health-related quality of life (HRQoL) are present in patients with foot disabilities, such as hallux valgus, plantar fasciitis, or minor toe deformities.

OBJECTIVE

The objective was to analyze the foot health status in patients with and without foot problems in a rural population and its relationship with quality of life.

MATERIAL AND METHODS

A prospective case-control study was developed with a sample of 152 patients, 76 subjects with podiatric pathologies and 76 without, in a rural population. HRQoL was measured through the SF-36 Health Questionnaire in the Spanish version.

RESULTS

The case group had a mean age of 49.18 ± 14.96 and the control group 44.16 ± 11.79. Regarding the score of the lowest levels of quality of life related to foot problems, the case group compared to the controls showed: for physical function (79.86 ± 26.38 vs. 92.63 ± 11 0.17, p < 0.001); for the physical role (73.68 ± 41.00 vs. 88.48 ± 27.51, p < 0.0022); for body pain (45.81 ± 27.18 vs. 73.68 ± 41.00, p < 0.035); and for general health (60.36 ± 30.58 vs. 68.71 ± 18.52, p < 0.047). The differences between groups were analyzed using the Mann-Whitney U test, which showed statistical significance (P < 0.05).

CONCLUSIONS

In the rural population, people with foot pathologies present a worse quality of life compared to those who do not present foot pathology, especially for the health domains: physical function, physical role, body pain and health general.

Effects of Manual Therapy on the Diaphragm in the Musculoskeletal System: A Systematic Review

OBJECTIVES

To analyze the effects at the musculoskeletal level of manual treatment of the diaphragm muscle in adults.

DATA SOURCES

Systematic review using 4 databases: PubMed, Science Direct, Web of Science, and Scopus.

STUDY SELECTION AND DATA EXTRACTION

Two independent reviewers applied the selection criteria and assessed the quality of the studies using the Physiotherapy Evidence Database scale for experimental studies. A third reviewer intervened in cases where a consensus had not been reached. A total of 9 studies were included in the review.

DATA SYNTHESIS

Manual therapy directed to the diaphragm has been shown to be effective in terms of the immediate increase in diaphragmatic mobility and thoracoabdominal expansion. The immediate improvement in the posterior muscle chain flexibility test is another of the most frequently found findings in the evaluated studies. Limited studies show improvements at the lumbar and cervical level in the range of motion and in pain.

CONCLUSION

Manual diaphragm therapy has shown an immediate significant effect on parameters related to costal, spinal, and posterior muscle chain mobility. Further studies are needed, not only to demonstrate the effectiveness of manual diaphragm therapy in the long-term and in symptomatic populations, but also to investigate the specific neurophysiological mechanisms involved in this type of therapy.

Impressions on Reliability and Students' Perceptions of Learning in a Peer-Based OSCE

BACKGROUND

Peer assessment of performance in the objective structured clinical examination (OSCE) is emerging as a learning instrument. While peers can provide reliable scores, there may be a trade-off with students' learning. The purpose of this study is to evaluate a peer-based OSCE as a viable assessment instrument and its potential to promote learning and explore the interplay between these two roles.

METHODS

A total of 334 medical students completed an 11-station OSCE from 2015 to 2016. Each station had 1-2 peer examiners (PE) and one faculty examiner (FE). Examinees were rated on a 7-point scale across 5 dimensions: Look, Feel, Move, Special Tests and Global Impression. Students participated in voluntary focus groups in 2016 to provide qualitative feedback on the OSCE. Authors analysed assessment data and transcripts of focus group discussions.

RESULTS

Overall, PE awarded higher ratings compared with FE, sources of variance were similar across 2 years with unique variance consistently being the largest source, and reliability (r _φ ) was generally low. Focus group analysis revealed four themes: Conferring with Faculty Examiners, Difficulty Rating Peers, Insider Knowledge, and Observing and Scoring.

CONCLUSIONS

While peer assessment was not reliable for evaluating OSCE performance, PE's perceived that it was beneficial for their learning. Insight gained into exam technique and self-appraisal of skills allows students to understand expectations in clinical situations and plan approaches to self-assessment of competence.

Concurrent Validity of the Foot Health Status Questionnaire and Study Short Form 36 for Measuring the Health-Related Quality of Life in Patients with Foot Problems

Background and Objectives: Foot problems may be considered to be a prevalent condition and impact the health-related quality of life (QoL). Considering these Spanish-validated tools, the Foot Health Status questionnaire (FHSQ) may provide a health-related QoL measurement for specific foot conditions and general status. To date, the domains of the FHSQ and Medical Outcomes Study Short Form 36 (SF-36) have not been correlated. Therefore, the main aim of this study was to correlate the domains of the FHSQ and SF-36 in patients with foot problems. Materials and Methods: A cross-sectional descriptive study was carried out. A sample of 101 patients with foot problems was recruited. A single researcher collected descriptive data, and outcome measurements (FHSQ and SF-36) were self-reported. Results: Spearman's correlation coefficients (r_s) were calculated and categorized as weak (r_s = 0.00-0.40), moderate (r_s = 0.41-0.69), or strong (r_s = 0.70-1.00). In all analyses, statistical significance was considered with a p-value < 0.01 with a 99% confidence interval. Statistically significant differences (p < 0.01) were found between all domains of FHSQ and SF-36, except for the mental health domain of the SF-36 with foot pain, foot function, and general foot health of the FHSQ, as well as between the vitality domain of the SF-36 and the general foot health domain of the FHSQ (p > 0.01). Statistically significant correlations varied from week to strong (r_s = 0.25-0.97). The strongest correlations (p < 0.001) were found for physical activity and physical function (r_s = 0.94), vigor and vitality (r_s = 0.89), social capacity and social function (r_s = 0.97), and general health domains of the SF-36 and FHSQ. Conclusions: The FHSQ and SF-36 showed an adequate concurrent validity, especially for the physical activity or function, vigor or vitality, social capacity or function, and general health domains. Nevertheless, the mental health domain of the SF-36 should be considered with caution.

Evaluation of foot health related quality of life in individuals with foot problems by gender: a cross-sectional comparative analysis study

OBJECTIVE

Foot problems (FP) may be considered to be a prevalent conditions in people but there is limited evidence of their effect on the quality of life (QoL) related to foot health in men and women. The aim of this study was to assess the impact of FPs on both overall foot health and QoL, stratified by gender.

DESIGN

A cross sectional study.

SETTING

Clinic of Podiatric Medicine and Surgery at University of A Coruña in the city of Ferrol (Spain).

SUBJECTS

The sample consisted of 1647 participants with FP; the total population of the sample had a mean age of 43.24±19.89 years, with mean ages 44.09±21.36 years and 42.94±19.34 years for men and women, respectively.

METHODS

Measurement of sociodemographic characteristics include age, sex and body mass index. The Foot Health Status Questionnaire (FHSQ) was used to evaluate the general health and foot health. Differences between groups were evaluated by means of a t-test for independent samples.

RESULTS

Women with FP showed significantly lower scores in the domains of Foot Pain, Foot Function, Footwear, General Foot Health, Physical Activity and Vigour, and there was no difference compared with men in the domains of Overall Health and Social Capacity.

CONCLUSIONS

Women with FP present a negative impact on QoL related to foot health as compared with men except in the domains of Overall Health and Social Capacity, which appears to be associated with the presence of foot conditions.

Better arthritis care: What training do community-based health professionals need to improve their care of people with arthritis? A Delphi study

OBJECTIVE

The aim of the present study was to identify the competencies that non-specialist community-based nurses and allied health professionals (AHPs) need to enable them to assess, care for and manage arthritis appropriately.

METHODS

A Delphi survey with an expert panel of 43 rheumatology specialists and expert patients was used to identify the competencies needed by community-based nurses and AHPs to enable them to improve their care of people with arthritis. The process was informed by feedback from focus groups with arthritis patients, community-based nurses and AHPs.

RESULTS

The core competencies in arthritis care needed by non-specialist community-based nurses and AHPs were identified. The key goals identified were to increase the understanding of arthritis and its impact on patients' lives, and to increase the ability to help patients to self-manage their condition and access support. Competencies included an understanding of the pathology underlying inflammatory and non-inflammatory arthritis, the ability to distinguish between the two and the ability to recognize early warning signs, with an emphasis on osteoarthritis (OA), rheumatoid arthritis, gout and septic arthritis. Essential competencies included the ability to engage in shared decision making, goal setting and signposting, to provide patients with education and information and to make appropriate referrals.

CONCLUSIONS

Health professionals working in the community commonly encounter arthritis as a presenting problem or as a co-morbidity. The quality of care provided to people with inflammatory arthritis and OA in the community is currently variable. The present study identified the core competencies that all community-based nurses and AHPs should have in relation to OA and inflammatory arthritis.

Do rheumatologists know how to squeeze? Evaluations of Gaenslen´s maneuver

The Gaenslen´s compression maneuver is the application of pressure on the metacarpophalangeal joints in order to evoke pain on a patient who has active synovitis. The results from the use of the maneuver are seen as controversial due to the lack of information describing the technique required for this procedure. The present study will aim to clarify uncertainty in regard to the form, pressure, and time required to apply the maneuver by rheumatologist. Rheumatologist were observed and monitored while performing the Gaenslen compression maneuver on a prosthetic, biomedical device. The device was shaped to mimic a human hand and equipped with a sensor to monitor the force and time of which the pressure was applied. One hundred and eight (62 %) participants gave a valid recording. From these, 121 (87.7 %) were made by certified rheumatologists. The most predominant method (104 physicians/75.4 %) of applying the maneuver was by using the right hand with superior approach. The median strength calculated in grams resulted in 299 gr (IQR 145) (range 150-741 gr). The median time expressed in milliseconds was of 956.6 ms (IQR 824.6) . This is the first study to assess a clinical maneuver in a qualitative and quantitative manner. The results from this study, more specifically the low number of usable recordings, and the wide range of force exerted in the squeeze test may explain the differences in sensitivity and specificity in clinical studies.

Teaching musculoskeletal examination skills to UK medical students: a comparative survey of Rheumatology and Orthopaedic education practice

BACKGROUND

Specialists in Rheumatology and Orthopaedics are frequently involved in undergraduate teaching of musculoskeletal (MSK) examination skills. Students often report that specialty-led teaching is inconsistent, confusing and bears little resemblance to the curricula. The Gait, Arms, Legs and Spine (GALS) is a MSK screening tool that provides a standardised approach to examination despite it being fraught with disapproval and low uptake. Recent studies would appear to support innovative instructional methods of engaging learners such as patient educators and interactive small group teaching.

METHODS

This comparative cross-sectional survey evaluates the current state of undergraduate teaching in Rheumatology and Orthopaedics, including preferred teaching methods, attitudes towards GALS, and barriers to effective teaching. An electronic questionnaire was sent to specialist trainees and Consultants in the East and West Midlands region, representing 5 UK medical schools. Descriptive statistical data analysis was performed.

RESULTS

There were 76 respondents representing 5 medical schools. There was a request for newer teaching methodologies to be used: multi-media computer-assisted learning (35.5%), audio-visual aids (31.6%), role-playing (19.7%), and social media (3.9%). It is evident that GALS is under-utilised with 50% of clinicians not using GALS in their teaching.

CONCLUSIONS

There is a genuine desire for clinical educators to improve their teaching ability, collaborate more with curriculum planners, and feel valued by institutions. There remains a call for implementing a standardised approach to MSK clinical teaching to supersede GALS.

The foot and ankle examination

Most foot and ankle disorders can be diagnosed after a proper history and clinical examination and can be effectively managed in a primary care setting. It is important to assess the entirety of patient disorders that present as they can be multifactorial in cause. A broad differential should include disorders of bones, joints, muscles, neurovasculature, and surrounding soft tissue structures. Physical examination should be thorough and focused on inspection, palpation, range of motion, and appropriate special tests when applicable. This article highlights some of the salient features of the foot and ankle examination and diagnostic considerations.

Screening for signs and symptoms of rheumatoid arthritis by family physicians and nurse practitioners using the Gait, Arms, Legs, and Spine musculoskeletal examination

OBJECTIVE

To evaluate the sensitivity and specificity of the Gait, Arms, Legs, and Spine (GALS) examination to screen for signs and symptoms of rheumatoid arthritis (RA) when used by family physicians and nurse practitioners.

METHODS

Participating health care professionals (2 rheumatologists, 3 family physicians, and 3 nurse practitioners) were trained to perform the GALS examination by viewing an instructional DVD and attending a training workshop. One week after training, the health care professionals performed the GALS examination on 20 individuals with RA and 21 individuals without RA. All participants were recruited through 2 rheumatology practices, and each participant was assessed by 4 health care professionals. The health care professionals were asked to record whether observed signs and symptoms were potentially consistent with a diagnosis of RA. The health care professionals understood the study objective to be their agreement on GALS findings among one another and were unaware that one-half of the participants had RA. Sensitivity and specificity were calculated to determine the ability of the GALS examination to screen for RA using the rheumatologist as the standard for comparison.

RESULTS

Sensitivity and specificity values varied from 60-100% and 70-82%, respectively, for the 3 family physicians, and 60-90% and 73-100%, respectively, for the 3 nurse practitioners.

CONCLUSION

Following a very short training period, family physicians and nurse practitioners appeared to be able to use the GALS examination as a screening tool for RA signs and symptoms, particularly for identifying an individual with positive results who will benefit from further investigation or rheumatology referral.

Sensitivity of standardised musculoskeletal examination of the hand and wrist joints in detecting arthritis in comparison to ultrasound findings in patients attending rheumatology clinics

The aim of this study is to standardise the muscuoloskeletal (MSK) examination of the hand and wrist joints and to determine the sensitivity of this standard exam to diagnose arthritis in comparison to ultrasound (US) findings. A standardised approach to MSK examination of the hand and wrist joints was formulated. It consists of inspection, followed by screening exam based on active range of motion testing, and then using specific techniques to detect clinical swelling and tenderness. The scissor and squeeze techniques for metacarpophalangeal (MCP) joints, 4-finger technique for the proximal interphalangeal (PIP) joints and 2-thumb technique for the wrist joints. Patients aged 18-75 years with symptoms suggestive of inflammatory arthritis for more than 3 months were included in the study from two centres. Two rheumatologists conducted MSK examination, while a grayscale with power Doppler US was performed by two ultrasonographers recording signs of arthritis (effusion, proliferation and hyperaemia) on the same day of visit. Statistical analysis was carried out to compare MSK examination findings in detecting swelling and tenderness to US examination findings. A total of 2,112 joints were assessed both clinically and with US. Using a standard MSK examination by a rheumatologist to detect clinical swelling showed the following sensitivities as compared to US findings: 4-finger technique of 69 % in third PIP, the scissor technique of 74 % in second MCP and 70 % in third MCP, and the 2-thumb technique of 80 % at the wrist joint. The MCP squeeze technique showed sensitivity of 66 % for tenderness. A standard MSK examination with its described techniques is a sensitive tool if used appropriately to diagnose clinical arthritis as compared to US.

Musculoskeletal education in US medical schools: lessons from the past and suggestions for the future
