• Conditions: Achilles Tendinopathy

• Registration Number: NCT06986759
• Lead Sponsor: Riphah International University

Brief Summary

Achilles tendinopathy is a prevalent condition characterized by pain, swelling, and impaired function of the Achilles tendon, commonly affecting athletes and active individuals. The disorder arises from a failed healing response, leading to degenerative changes in the tendon without significant inflammation. It is categorized into insertional (at the calcaneus-Achilles junction) and non-insertional (2-6 cm proximal to the insertion) types. Intrinsic risk factors include biomechanical abnormalities and systemic conditions like diabetes and hypertension, while extrinsic factors involve excessive mechanical load and training errors. Effective management of Achilles tendinopathy is crucial for preventing long-term disability and ensuring the continuation of physical activities.

Detailed Description

This study is a randomized clinical trial aimed at comparing the effectiveness of laser therapy and extracorporeal shock wave therapy on pain, range of motion, and function in patients with Achilles tendinopathy. The trial will be conducted at Hameed Latif Hospital, Lahore, Punjab, over a duration of nine months. A total of 44 participants, aged 18-40, diagnosed with Achilles tendinopathy and meeting specific inclusion criteria, will be randomly allocated into two groups using a lottery method. Group A will receive laser therapy, and Group B will undergo extracorporeal shock wave. Baseline and post-treatment measurements will be taken using the Visual Analogue Scale , Foot and Ankle Outcome Score , and goniometric measurements for range of motion. The data will be analyzed using SPSS software to evaluate the effectiveness of each treatment modality. For Group A, laser therapy will be administered using the Laser Therapy Unit, a class 3B laser with an 810-nm, 100-milliwatt infrared probe. The treatment will be applied to six standardized points around the Achilles tendon for 30 seconds each, providing a total dose of 18 joule per session. Group B will receive extracorporeal shock wave with each session involving 1500-3000 pulses at a frequency of 1-4 Hertz. Treatments will be conducted once a week for three weeks, with a one-week break between sessions. Both therapies aim to reduce pain and improve function by enhancing the healing processes of the damaged tendon.

Primary Outcome Measures

Name	Time	Method
Numeric pain rating scale	4 weeks	The pain NPRS is a unidimensional measure of pain intensity, used to record patients' pain progression, or compare pain severity between patients with similar conditions. Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no pain" anchor and the patient's mark, providing a range of scores from 0-100. A higher score indicates greater pain intensity. It has been shown that NPRS is valid, reliable and interval scale. NPRS has high test-retest reliability of ICC 0.98.

Secondary Outcome Measures

Name	Time	Method
Foot and ankle outcome	4 weeks	The FAOS is a patient-reported foot- and ankle-specific questionnaire including 42 items in 5 subscales evaluating pain, symptoms, function of daily living (ADL), function in sport and recreation (sport/rec), and quality of life (QOL). The outcome of FAOS is calculated based on a standardized scoring algorithm given a score between 0 and 100 for each of the 5 subscales. A score of 100 indicates the best possible results and 0 the worst outcome. Test-retest reliability shows intraclass correlation coefficient (95% confidence interval) was calculated as 0.94 (0.89-0.96
