Detailed Description
After eligibility has been confirmed, participants are instructed in performing the exercise which will be heel raises. Participants will be asked to complete the exercise standing with the forefoot on a step. The toes are maximally extended by placing a towel underneath them. The participant is instructed to perform a heel raise to maximal plantar flexion in the ankle joint and afterwards to lower the heel to maximal dorsiflexion. Supporting oneself for balance by touching the hands on a wall or a rail is allowed. The participants are instructed in performing the exercise with a load as heavy as possible but no higher than 8RM and for as many sets as possible. If the participants feel they can perform more repetitions than their load corresponds to (e.g. 10 repetitions when the load is supposed to be 8RM) an external load consisting of a backpack with books or water bottles to add weight will be used. Participants are asked to start performing the exercise as soon as they feel ready but not before 24 hours after the injection.
Participants will receive patient education on what is known about the condition in terms of risk factors and aetiology, the pathology, activity modification, and the rationale for why the combination of heavy slow resistance training and an US-guided corticosteroid injection could lead to recovery. They will be told that compliance to the exercise programme is very important and that compliance to the exercises is associated with their recovery. They are also informed about other types of evidence-based treatments however, they are asked to refrain from seeking other treatments during the course of the study. A silicone heel cup will be given to all participants and they are asked to use the heel cup as much as possible. If the participant already uses an insole or any other type of foot orthosis they will be allowed to continue wearing this if they do not want to use the heel cup. Participants are asked not to progress the method used to achieve 8RM when they start to do the exercise after the injection until Week 3 of the exercise program. If standing on both feet was sufficient to achieve 8RM at baseline, the participant must not perform the exercise single-legged after the injection regardless of any pain reduction afforded by the injection.
Participants receive an ultrasound-guided corticosteroid injection between 5 and 8 days after baseline. A 21-gauge, 40 mm needle is connected to a 2.5 cm3 syringe filled with 1 ml Triamcinolonhexacetonid (Lederspan, Meda) + 1 ml Lidocain 10 mg7ml (Xylocain, AstraZeneca). The skin is cleansed with Chlorhexidine alcohol 0.5 % (Medic). The needle is inserted with a medial approach under ultrasound-guidance aligned to the long axis of the ultrasound transducer. The injection is placed anterior to the plantar fascia insertion on the calcaneal bone in the region of maximal fascia thickness. If participants are not categorised as improved based on the Global Rating of Change after the 8 weeks of exercise they will be offered to receive a second injection and are advised to continue performing the exercise. These participants will have an additional follow-up 8 weeks after the second injection.
All statistical analyses will be performed according to a pre-established analysis plan. STATA ver. 14 will be used as statistical software.
Feasibility outcomes To conclude that the combined interventions are feasible the following three criteria will need to be met: i) ≥10/20 rate the combined interventions as "acceptable". The rationale for choosing this criterion is that the effect of the combined interventions has yet to be established and effective treatment could justify the use of an intervention that is slightly uncomfortable or considered slightly unacceptable by patients (e.g. chemo therapy is a very uncomfortable treatment but is tolerated and accepted by patients because of the potential effective outcome). Any dropouts after the injection will be dichotomized as "unacceptable". ii) based on the self-reported training diaries ≥15/20 participants will need to have performed ≥20/27 possible training sessions; and iii) ≥15/20 participants will need to have started performing the exercise ≤7 days after the injection. Weekly recruitment rate will be reported using descriptive statistics.
Explorative quantitative outcomes Any changes in FHSQ, IPAQ, and PSEQ will be examined using a one-way repeated measures ANOVA, with time (baseline assessment, 4 weeks, or 8 weeks) as the independent factor, and FHSQ, IPAQ or PSEQ, respectively, as the dependent variable. Changes in plantar fascia thickness from baseline assessment to the 8-week follow-up and the difference in mean daily heel pain from before to after the injection will be examined using paired t-tests. GROC will be reported using descriptive statistics.
If any participant decides to drop out before having received the injection a new participant will be recruited.

Participants will complete a heel raise standing with the forefoot on a step. The toes are maximally dorsiflexed by placing a towel underneath them. The heel raise is performed with a raise to maximal plantar flexion and to maximal dorsi flexion. The exercise is performed with a load as heavy as possible but no heavier than 8RM and for as many sets as possible every other day.
Participants receive an ultrasound-guided corticosteroid injection between 5 and 8 days after baseline.
A 21-gauge, 40 mm needle is connected to a 2.5 cm3 syringe filled with 1 ml Triamcinolonhexacetonid (Lederspan, Meda) + 1 ml Lidocain 10 mg7ml (Xylocain, AstraZeneca).
The skin is cleansed with Chlorhexidine alcohol 0.5 % (Medic).
The needle is inserted with a medial approach under ultrasound-guidance aligned to the long axis of the ultrasound transducer.
The injection is placed anterior to the plantar fascia insertion on the calcaneal bone in the region of maximal fascia thickness.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Acceptability
Time Frame: At the 8-week follow-up
|
Acceptability of the combined interventions measured by a participant acceptability questionnaire that includes a 7-point Likert scale ranging from "very unacceptable" to "very acceptable".
This is not a measure of whether the participant's symptoms have improved to a point where they are recovered or feel close to recovery but if it matches their expectations to the content of the intervention and acceptability of performing exercise after receiving an injection.
This will be clearly stated on the questionnaire to emphasise that improvement is not to be considered.
The combined interventions are categorised as "unacceptable" if they are rated as "very unacceptable" or "unacceptable" (category 1-2) and categorised as "acceptable" if they are rated from "slightly unacceptable" to "very acceptable" (category 3-7).
|
At the 8-week follow-up
|
Compliance
Time Frame: From baseline to the 8-week follow-up
|
Compliance to the exercises as measured by the mean number of training sessions performed per week throughout the intervention measured by a training diary that each participant is handed out at baseline.
The participants will be instructed in filling out the number of repetitions and sets performed and the day on which they performed the exercise
|
From baseline to the 8-week follow-up
|
Recruitment rate
Time Frame: From start of recruitment until the 20th participant has been recruited, assessed up to 12 months
|
Mean number of participants recruited per week
|
From start of recruitment until the 20th participant has been recruited, assessed up to 12 months
|
Exercise start
Time Frame: From date of injection to exercise start assessed up to 8 weeks
|
Mean days until the participant starts to perform the exercises from the two days after the injection based on training diary data.
Participants are asked to start performing the exercise as soon as they feel ready but not before two days after the injection.
|
From date of injection to exercise start assessed up to 8 weeks
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in Foot Health Status Questionnaire
Time Frame: At baseline and at the 4- and 8-week follow-ups
|
Ranging from 0 (poor foot health) to 100 (optimum foot health)
|
At baseline and at the 4- and 8-week follow-ups
|
Change in mean daily heel pain measured on an 11-point Numerical Rating Scale (NRS)
Time Frame: From baseline to one week after injection
|
Participants receive a daily SMS asking them to rate their mean heel pain during the past 24 hours on an NRS (ranging from 0 (no pain) to 10 (worst pain imaginable)) from the day after baseline to one week after the injection
|
From baseline to one week after injection
|
Global Rating of Change
Time Frame: At the 8-week follow-up
|
This will be used to measure the participants' self-reported recovery on a 7-point Likert scale ranging from "much improved" to "much worse".
Participants are categorised as improved if they rate themselves as "much improved" or "improved" (category 6-7) and categorised as not improved if they rate themselves from "slightly improved" to "much worse" (category 1-5).
|
At the 8-week follow-up
|
Change in plantar fascia thickness
Time Frame: At baseline and at the 8-week follow-up
|
Measured in millimeters using ultrasonography
|
At baseline and at the 8-week follow-up
|
Change in Pain Self-Efficacy Questionnaire score
Time Frame: At baseline and at the 4- and 8-week follow-ups
|
The Pain Self-Efficacy Questionnaire ranges from 0 (not at all confident) to 60 (completely confident) with lower scores indicating lower self-efficacy.
A Danish translation of the original questionnaire, which has been validated in a Danish chronic pain population, will be used.
|
At baseline and at the 4- and 8-week follow-ups
|
Change in physical activity level
Time Frame: At baseline and at the 4- and 8-week follow-ups
|
This will be measured using the International Physical Activity Questionnaire short form (IPAQ).
A Danish translation of the original questionnaire will be used.
The IPAQ is the most commonly used questionnaire for measuring physical activity among adults and consists of 9 items that provide information on the time spent performing vigorous and moderate activities, the time spent walking, and time spent sedentary during the past week.
The IPAQ gives an estimate of the total weekly physical activity measured in MET-minutes per week and total minutes spent sitting
