Brief Summary

In recent years, numerous technological products and devices have been developed in rehabilitation through advances in biomedical technology. These innovations support traditional rehabilitation services, offering more effective treatment methods and improving patients' adherence and participation. Increased compliance in treatment positively influences functional status, quality of life, and satisfaction. However, the diversity of biomedical products and the varying strength of their scientific foundations make it critical to evaluate them in terms of benefit, patient compliance, and usability. In physiotherapy and rehabilitation, objective tools for this purpose remain limited, which hinders accurate assessment of product effectiveness and the identification of improvements. Uncertainty regarding usability and ease of use may also result in inefficient utilization of resources. Questionnaires provide cost-effective tools to capture users' opinions, reflecting strengths and weaknesses of a product without the need for measurement devices. The Usefulness, Satisfaction, and Ease of Use (USE) Questionnaire, developed by Arnold Lund in 2001, is a comprehensive 30-item scale scored on a 7-point Likert system. It evaluates usefulness, ease of use, ease of learning, and satisfaction, with items applicable across different products and services such as software, hardware, applications, or user support materials. Its multidimensional structure allows for the evaluation of usability in physiotherapy and rehabilitation technologies as well as in broader fields including robotics, social networking sites, diagnostic tools, and virtual reality. Despite its wide use internationally, no validated Turkish version of the USE Questionnaire exists. Establishing a culturally adapted, valid, and reliable Turkish version will address this gap and provide clinicians and researchers with a standardized tool for usability assessment. The aim of this study is to investigate the validity and reliability of the Turkish version of the USE Questionnaire.

Outcome Measures

Primary Outcomes (4)

• Neck Disability Index

  It was developed by Vernon and colleagues as a neck version of the Oswestry Back Pain Scale. The Turkish version was developed by Aslan and colleagues. The Neck Disability Questionnaire consists of a total of 10 questions related to pain, personal care, concentration, work, driving, and sleeping. Each question is scored on a scale of 0 to 5. The total score is evaluated out of 50.

  Baseline (Day 1)

• Usefulness, Satisfaction, and Ease of Use Questionnaire

  Developed by Arnold Lund in 2001, the Usefulness, Satisfaction, and Ease of Use Questionnaire (USE) is a comprehensive tool consisting of 30 items that assess various dimensions of usability. The questionnaire is scored on a 7-point Likert scale (1 = "Strongly Disagree"; 7 = "Strongly Agree") and includes a "None" option.

  Baseline (Day 1) and 3 days after initial assessment

• Oswestry Disability Index

  Developed by Fairbank et al. to assess the level of functional loss in individuals with back pain. The Turkish version was developed by Yakut et al. The scale consists of 10 questions related to pain intensity, self-care, lifting and carrying, walking, sitting, standing, sleeping, degree of pain change, travel, and social life. Each question is scored on a scale of 0 to 5. The total score is evaluated out of 100.

  Baseline (Day 1)

• Quebec Assistive Technology User Satisfaction Survey

  The Quebec Assistive Technology User Satisfaction Evaluation (Q-YTKMD) Questionnaire is a standardized questionnaire widely used to assess the satisfaction of individuals who use various assistive devices. The Q-YTKMD Questionnaire contains 12 items that inquire about satisfaction with assistive devices (8 items) and services (4 items). The validity and reliability of the Turkish version of the Q-YTKMD Survey have been established.

Study Arms (1)

People with low back and neck pain

Participants will be adults aged 18-65 years who have experienced low back or neck pain for at least 3 months and have undergone rehabilitation including at least one biomedical device (e.g., Back Up, Mollii Suit, Compex, or TENS). Eligible individuals must be literate and willing to provide informed consent. Exclusion criteria include malignancy, pregnancy, neurological or systemic disease causing functional loss, recent surgery within the last 6 months, acute infection, unhealed fracture, or withdrawal of consent.

Interventions

back up, mollii-suit, compex, tens DEVICE

In order to be included in this study, individuals must have undergone at least one session of treatment with a biomedical device. In the validity and reliability study of the Turkish version of the questionnaire, permission was first obtained from the questionnaire's author via e-mail. The Usefulness, Satisfaction and Ease of Use Questionnaire (USE) was translated from English into Turkish by two independent translators: one was a physiotherapist with a doctoral degree, and the other a faculty member at Hacettepe University School of Foreign Languages. Both translators were native Turkish speakers, fluent in English, and had no personal or professional interaction with each other. They evaluated the original questionnaire in terms of meaning and grammar to produce the Turkish version of the Usefulness, Satisfaction and Ease of Use Questionnaire (USE). The independently translated Turkish versions of the questionnaire were then reviewed by an expert panel to reach consensus. This exp
