A pilot randomised trial comparing individualised physiotherapy versus shockwave therapy for proximal hamstring tendinopathy: a protocol.

PURPOSE: Proximal hamstring tendinopathy (PHT) presents as localised lower buttock pain with tasks such as squatting and sitting. It is a condition that occurs at all ages and levels of sporting participation and can cause disability with sport, work, and activities of daily living. This paper details a pilot trial protocol for investigating the effectiveness of individualised physiotherapy compared to extracorporeal shockwave therapy (ESWT) on pain and strength in people with PHT. METHODS: The study is an assessor-blinded, pilot randomised controlled trial (RCT). One hundred participants with PHT will be recruited from the local community and sporting clubs. Participants will be randomised to receive six sessions of either individualised physiotherapy or ESWT, with both groups also receiving standardised education and advice. Primary outcomes will be global rating of change on a 7-point Likert scale, and the Victorian Institute of Sport-Hamstring (VISA-H) scale, measured at 0, 4, 12, 26 and 52 weeks. Secondary outcomes will include sitting tolerance, the modified Physical Activity Level Scale, eccentric hamstring strength, modified Tampa scale for kinesiophobia, the Örebro Musculoskeletal Pain Screening Questionnaire Short Form (ÖMPSQ-SF), Numerical Pain Rating Scale (NPRS) for average and worst pain, participant adherence, the Pain Catastrophizing scale, satisfaction scores, and quality of life. Data will be analysed on an intention to treat basis, with between-group effects estimated using linear mixed models for continuous data and Mann Whitney U tests for ordinal data. CONCLUSIONS: This pilot RCT will compare individualised physiotherapy versus ESWT for PHT. The trial will determine feasibility and estimated treatment effects to inform a definitive trial in the future. TRIAL REGISTRATION: The trial has been prospectively registered with the Australia & New Zealand Clinical Trials Registry (ACTRN12621000846820), registered 1 July 2021, https://www.anzctr.org.au/Trial/Registration/TrialReview.aspx?id=373085.

Complexity in the physiotherapy management of low back disorders: clinical and research implications.

Over the past decade a wide variety of approaches for the management of low back disorders (LBD) have been developed and evaluated in clinical trials. As a consequence physiotherapists and researchers interested in LBD are faced with a range of issues to do with complexity. These issues will be explored and suggestions made to improve the delivery of high quality research evidence and better patient outcomes.

Pathoanatomy and classification of low back disorders.

Over the past decade research into the effectiveness of low back disorders (LBDs) has focused on the classification of subgroups more likely to respond to specific treatment. Much of this research has explicitly excluded a focus on pathoanatomical factors based on a questionable interpretation of the biopsychosocial model. Common justifications and potential issues with this approach are explored with recommendations made for future clinical and research practice.

The test-retest reliability and concurrent validity of the Subjective Complaints Questionnaire for low back pain.

Physiotherapists commonly record detailed patient information regarding subjective complaints for low back pain (LBP), particularly to assist in the process of classifying patients into specific subgroups. A self-administered Subjective Complaints Questionnaire for LBP (SCQ-LBP) measuring such information was developed for the purposes of future clinical research, particularly in the area of LBP classification. The development comprised literature review, feedback from experienced physiotherapists and pilot questionnaire testing in a patient population. Test-retest reliability of the questionnaire in a self administered format as well as concurrent validity against a suitable reference standard was evaluated. The agreement between the self administered questionnaire compared to when administered by a physiotherapist was also tested as the latter method is the most common form of retrieving subjective complaints in clinical practice. Thirty participants with LBP were recruited and at least moderate test-retest reliability was demonstrated in 56 of the 57 self administered questionnaire items. Preliminary evidence was found supporting the concurrent validity of selected items. At least moderate agreement was demonstrated in 51 of the 57 items when comparing between the self administered and physiotherapist administered conditions. The questionnaire is a useful tool for collecting subjective complaints information, particularly for clinical research on the classification of LBP, however, further research regarding validity is required.
