Does a corticosteroid injection plus exercise or exercise alone add to the effect of patient advice and a heel cup for patients with plantar fasciopathy? A randomised clinical trial.

OBJECTIVE: To compare the effectiveness of patient advice plus heel cup alone (PA) versus PA and lower limb exercise (PAX) versus PAX plus corticosteroid injection (PAXI) to improve self-reported pain in patients with plantar fasciopathy. METHODS: We recruited 180 adults with plantar fasciopathy confirmed by ultrasonography for this prospectively registered three-armed, randomised, single-blinded superiority trial. Patients were randomly allocated to PA (n=62), PA plus self-dosed lower limb heavy-slow resistance training consisting of heel raises (PAX) (n=59), or PAX plus an ultrasound-guided injection of 1 mL triamcinolone 20 mg/mL (PAXI) (n=59). The primary outcome was changed in the pain domain of the Foot Health Status Questionnaire (ranging from 0 'worst' to 100 'best') from baseline to the 12-week follow-up. The minimal important difference in the pain domain is 14.1 points. The outcome was collected at baseline and at 4, 12, 26, and 52 weeks. RESULTS: The primary analysis found a statistically significant difference between PA and PAXI after 12 weeks favouring PAXI (adjusted mean difference: -9.1 (95% CI -16.8 to -1.3; p=0.023)) and over 52 weeks (adjusted mean difference: -5.2 (95% CI -10.4 to -0.1; p=0.045)). At no follow-up did the mean difference between groups exceed the pre-specified minimal important difference. No statistically significant difference was found between PAX and PAXI or between PA and PAX at any time. CONCLUSION: No clinically relevant between-group differences were found after 12 weeks. The results indicate that combining a corticosteroid injection with exercise is not superior to exercise or no exercise. TRIAL REGISTRATION NUMBER: NCT03804008.

Difference in postural stability between STarT Back Tool subgroups of patients with low back pain under conditions of sensory deprivation and cognitive load.

OBJECTIVE: We explored differences in postural stability between subgroups of patients with low back pain (LBP) and varying risk levels for developing chronicity measured using the Subgroups for Targeted Treatment (STarT) Back Tool. METHODS: This was a cross-sectional, single-session, double-blind experimental study among 65 participants who had LBP for more than 14 days. Postural stability was assessed by measuring the center of pressure (COP) range, displacement area, and velocity in anterior-posterior and mediolateral directions under four sensory and cognitive conditions: (i) eyes open and counting forward, (ii) eyes closed and counting forward, (iii) eyes closed and counting forward in multiples of seven, and (iv) eyes closed and counting backward in multiples of seven. The participants were stratified into low-/medium- (n = 53) and high-risk (n = 9) subgroups. RESULTS: There were no significant between-group differences among patients with LBP stratified as having a low/medium or high risk of chronicity in postural stability and sensory and cognitive conditions. CONCLUSIONS: Impaired postural stability is important to consider when treating patients with LBP. However, we found that these impairments were not strongly aggravated in groups with a higher risk of chronicity, as measured using the STarT Back Tool.

Care-seeking behaviour of adolescents with patellofemoral pain: a retrospective cohort study.

AIM: The aim of this study was to assess the care-seeking behaviour among adolescents with patellofemoral pain (PFP). METHODS: This retrospective study included data on 121 adolescents with PFP enrolled in a randomized controlled trial. A questionnaire was sent to the general practitioner (GP) of each adolescent, assessing information on the consultation dates for knee pain, potential diagnoses, and treatment provided. RESULTS: 106/121 adolescents had been in contact with their GP, and 95 medical records of adolescents were available. Of the 95 adolescents with available medical records 60 had consulted their GP for knee pain. The median number of contacts was 1.5 (range 1-7). The GPs initiated treatment for 48 of the 60 adolescents and in most cases it was information and advice (36/48) or pain medication to a minor extent (6/48). Out of the 60 adolescents who consulted their GP 26 were subsequently referred to different types of health care professionals, in 11 out of 26 to physiotherapy, but also to the department of rheumatology or orthopaedics. Conclusions : 63% of adolescents diagnosed with PFP had previously consulted their GP due to knee pain. Several types of treatments were initiated by the GP, but most commonly advice and information were given. Standardized and evidence-based treatment guidelines for adolescent knee pain in general practice are needed.

The Adolescent Knee Pain (AK-Pain) prognostic tool: protocol for a prospective cohort study.

Background: One in three children and adolescents experience knee pain. Approximately one in two adolescents with knee pain will continue to experience pain even five years later and have low quality of life. The general practitioner (GP) is the first point of contact for children and adolescents with knee pain in Denmark. There is a variety of treatments being delivered in general practice, despite similar symptoms and patients' characteristics. This suggests a need to support the GPs in identifying those at high risk of a poor outcome early on, in order to better allocate resources. The aim of this study is to develop a user-friendly prognostic tool to support GPs' management of children and adolescents' knee pain. Methods: A preliminary set of items in the prognostic tool were identified using systematic reviews and meta-analysis of individual participant data. Following feedback from GPs and children and adolescents on the content and understanding, the tool was piloted and implemented in general practice. A cohort of approximately 300 children and adolescents (age 8-19 years old) is being recruited from general practices (recruitment period, July 2019 - June 2020). Clinically meaningful risk groups (e.g. low/medium/high) for the recurrence/persistence of knee pain (at 3 and 6 months) will be identified. Discussion: If successful, this prognostic tool will allow GPs to gain insights into the likely prognosis of adolescents with knee pain and subsequently provide the first building blocks towards stratified care, where treatments will be matched to the patients' prognostic profile. This has the potential to improve the recovery of children and adolescents from knee pain, to improve the allocation of resources in primary care, and to avoid the decline in physical activity and potential associated health and social consequences due to adolescent knee pain. Registration: Registered with ClinicalTrials.gov on 24 June 2019 (ID NCT03995771).

Quality of life and functional status after revascularization or conservative treatment in patients with intermittent claudication.

UNLABELLED: Revascularization of patients with intermittent claudication (IC) is recommended only for selected patients who have chronic pain or disabling disease. However, improvement in the quality of life (QoL) could justify more widespread use. OBJECTIVES: To determine the effect of conservative treatment and revascularization on the QoL and physical performance of selected patients with IC. PATIENTS AND METHODS: This nonrandomized, parallel group, follow-up study included 83 patients with IC at Fontaine stage II. On the basis of interventional opportunities and the risks and benefits, combined with the preference of the patient, 47 patients were treated conservatively and 41 were revascularized. The patients were examined at inclusion and 3 months later. The evaluations included the QoL measure Short Form 36 (SF-36), the Walking Impairment Questionnaire (WIQ), pain-free and maximal walking distance (treadmill at 3 km/h, no incline), maximal isometric knee-extension strength and endurance, and ankle-brachial blood pressure index (ABI). RESULTS: At baseline, the SF-36 and WIQ scores and the ABI were significantly lower in the patients selected for revascularization. After revascularization, all dimensions of QoL and functional status increased significantly in the patients who underwent revascularisation compared with the patients treated conservatively. The difference in the change in the physical component summary of SF-36 was 29.4% (P < .001), in the total WIQ 63.6% (P = .0002), and in the pain-free and maximal walking distances 313% (P < .001) and 135% (P < .001), respectively. After adjustment for age, smoking, ABI, body mass index (BMI), and baseline values, the differences remained statistically significant. CONCLUSION: Revascularization above the knee increased QoL, functional status, and walking distance significantly in patients with moderate IC.
