Study type
Description of intervention(s) / exposure
60 patients with diagnosis of calcaneal spurs (basic group and placebo) intend to acquire research. Therapy will take place in the Clinical Research Laboratory at the State Medical University of Applied Sciences in Opole.
In the research project, it is planned to create 2 homogeneous comparative groups, using the principles of randomization patients will be assigned to particular groups:
• Group 1: the study (n = 30) will be administered in the form of 15 treatment sessions using a high-energy laser and standard therapy in the case of heel spur, it is ultrasounds (UD). Each treatment will be characterized by a contact method using labile movements in the area of the greatest pain.
HILT parameters: 7W, dose 149.9J / cm2, time 11 minutes and 53 seconds, spot applicator with 30cm2 cone breaker, wavelength 1064 nm (GaAlAs laser), 90% duty cycle, total energy 4496.
Treatments will be carried out 5 times a week for a period of 3 weeks with the need to maintain continuity of therapy (excluding weekends).
In order to follow the methodology of the scientific project, patients will be asked to sign up for the attendance list. The results will be saved on the patient's card and a computer file.
One physical therapist with 2 years of experience will deliver each treatment in each group
Intervention code [1] 300518 0
Comparator / control treatment
Group 2: control (n = 30) will be treated using ultrasound and sham surgery in the case of HILT. The parameters of the UD procedure will be the same as in Group 1, while performing a laser therapy, the therapist will only perform head movement while maintaining the principles of methodology that apply.
UD treatment parameters: 0.8W / cm2, 5 minutes at 1 MHz, filling factor 100%. Treatments will be carried out 5 times a week for a period of 3 weeks with the need to maintain continuity of therapy (excluding weekends).
Control group

Primary outcome [1] 305022 0
The foot function index has been used to measure the pathology of the foot function in terms of pain, disability and activity limitations.The FFI is a self-administered index consisting of 23 items divided into 3 sub-scales.
Timepoint [1] 305022 0
Primary endpoint: after 3 months
Before and after therapy sessions and follow-up after 1 month
Primary outcome [2] 305517 0
Stabilometric Platform analysis the position of posture with open and closed eyes (COP).

Primary endpoint: after 3 months
Before and after therapy sessions and follow-up after 1 month
Secondary outcome [1] 343904 0
The Laitinen scale was used for subjective assessment of the level of pain. The patient evaluated four indicators: pain severity, passenger frequencies, frequency of using analgesics, limitations of physical activity.
Each of the points is assigned points from 0 to 4, where 0 means no solution and the maximum problem is 4.
Timepoint [1] 343904 0
At baseline, after the last intervention and follow-up after 1 month and 3 months
Secondary outcome [2] 343905 0
Level of pain assesed by Visual Analogue Scale (VAS) in which the patient assesses the experienced pain on a simple scale from 0 to 10, where 0 denotes lack of pain and 10 denotes the strongest pain.
Timepoint [2] 343905 0
At baseline, after the last intervention and follow-up after 1 month and 3 months

Statistical methods / analysis
The obtained results will be subjected to statistical analysis made with the STATISTICA software. Power analysis in each group will be required and calculated to establish the statistical significance with a = 0.05 and power = 0.80 based on the estimated outcomes of 85% for therapeutic method. For measurable variables, the arithmetic mean, standard deviation, medians and extreme values (minimum and maximum) will be calculated. However for qualitative variables, the occurrence rates, will be expressed as a percentage. Homogeneity of the compared groups will be established in terms of selected characteristics of the participants, and the level of significance will be accepted at p>0.05. Results will be compared between the groups with comparative tests (independent), as well as each group results obtained before and after therapy (dependent tests). The type of statistical tests will be depend on the fulfilment of their objectives. Statistically significant differences at p<0.05.

Brief summary
The aim of the research project will be to observe the obtained results of therapy using high energy laser therapy and ultrasound. Conducting studies on a uniform, randomized group of patients, with an analogous development statistical analysis in accordance with the guidelines of evidence-based medicine (EBM), will help to answer questions about the effectiveness of treatments in a given disease unit. Research using a high-energy laser will be characterized by a high degree of innovation. To document the obtained results, it is planned to use non-invasive methods of measurement.
