About this study
Official title: Investigation of the Acute Effects of Different Physiotherapy Methods Applied to the Patellar Tendon: A Single-Blind Randomized Controlled Trial
This randomized controlled trial investigated the acute effects of different physiotherapy interventions applied to the patellar tendon. Participants were randomly assigned to one of four groups: deep friction massage, thermal agent application, quadriceps resistance exercise, or a control group. Each intervention was delivered in a single session. Outcomes of the study included changes in skin temperature, muscle strength, flexibility, and pulse rate. All measurements were taken immediately before the intervention and again immediately after, 15 minutes after, and 60 minutes after the intervention. The study was conducted with healthy adult volunteers. The results of this study are expected to contribute to a better understanding of how different physiotherapy modalities acutely influence the patellar tendon region.
Read the detailed description
This study examined the immediate physiological responses of the patellar tendon region following different physiotherapy interventions. Participants were allocated into four groups: (1) deep friction massage applied directly to the patellar tendon, (2) a locally applied superficial thermal agent, (3) a structured quadriceps resistance exercise protocol, and (4) a no-intervention control group. Each intervention was administered as a single session under standardized laboratory conditions.
Outcome measures included skin temperature assessed with thermal imaging, quadriceps muscle strength measured with a handheld dynamometer, flexibility assessed by standardized clinical procedures, and pulse rate. All measurements were collected at four time points: immediately before the intervention, immediately after, 15 minutes after, and 60 minutes after the intervention.
The study was conducted with healthy adult volunteers to evaluate the acute physiological effects of commonly used physiotherapy modalities on the patellar tendon region. The findings are intended to inform clinical decision-making by clarifying how different physiotherapy techniques influence tendon-related parameters within the first hour following treatment.

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Jan 2026.
