Course detail

Therapeutic and prothetic instruments

FEKT-BTPTAcad. year: 2018/2019

The principle and construction of instruments used in therapy and surgery - electrical stimulation, magnetotherapy, ionizing and non ionizing radiation, ultrasound and low temperature. Support and substitution of organs. Therapeutical effects on human organism.

Learning outcomes of the course unit

The student is able to:
- Explain the principles of physical therapy,
- Explain the impact of physical fields and describe their effects on the human body,
- Explain the principle of electrical stimulation and specify types of stimulators, including their usage,
- Describe the use of ultrasound in the treatment and its effects, indicate structural design of ultrasonic probes and devices,
- Indicate the possibility of using electromagnetic field therapy (diathermy, radiotherapy), to explain the principles of the method, to design simple applicators,
- Describe the effect of low temperatures on human tissue, describe the technical solutions of cryocauters,
- Describe the principle of support heart function and kidney function, explain technical solutions apparatus for these purposes,
- Explain the principle of hearing aids, indicate their types, propose a method of speech signal processing,
- Explain the role of computers in planning and management of therapy, give specific examples.


The subject knowledge on the secondary school level is required.

Planned learning activities and teaching methods

Techning methods include lectures and practical laboratories. Course is taking advantage of e-learning (Moodle) system. Students have to write few protocols about measurement.

Assesment methods and criteria linked to learning outcomes

Students must obtain at least 50 points out of 100 in the sub-activities:
1. laboratory tasks (min 15 points, max 30 points)
2. final exam (min 35 points, max 70 points).
Students are assessed in the laboratory, where they must demonstrate competence in the design part of the therapy equipment and measuring parameters of therapeutic devices. The final test checks student’s knowledge about the effects of physical fields on the human body and therapeutic technique.
