The purpose of this study is to determine the effectiveness of eccentric exercise combined with vibration or cryotherapy in Achilles tendon pathology. The investigators hypothesis is that the combined eccentric exercise is better than the results presented by the exclusive eccentric exercise. This intervention differs from the classic studies in that we maintain the intensity throughout the treatment.
Achilles tendon plays a significant role in walking and sporting activities, particularly through ankle joint and lower limbs stability. Ultrasound imaging can be the first-line examination of choice for patients suspected of having Achilles tendon injury, which is more and more frequent. Nowadays, ultrasound elastography can be used to evaluate the viscoelasticity properties of Achilles tendon, however little is known about the reproducibility of the technique. This study aims to evaluate the reproducibility of supersonic shear imaging SWE™ Young's modulus measurements of shear wave velocity (m/s) in Achilles tendon and plantar fascia.
The plantaris tendon is recognised as an important factor in non-insertional Achilles tendinopathy (NIAT). A biomechanical study found the plantaris tendon is stiffer and stronger than the Achilles tendon (AT), thus reducing its capacity to elongate in response to loading. This is hypothesized to result in friction between the AT and plantaris in some NIAT patients. Current treatment is conservative management: physiotherapy and high volume injection of the paratenon. However 29% of patients fail to respond to conservative management and those with plantaris related symptoms require its surgical excision and stripping of the ventral aspect of the AT through a 3cm medial incision. This is performed in theatres under general anaesthetic with good or excellent results reported in 90% of cases. Purely cutting the plantaris tendon using a minimally invasive endoscopic technique has also been successful. The plantaris tendon is easily visualized under ultrasound scan (USS) and tenotomy of tendons under USS guidance is performed elsewhere. Tenotomy of the plantaris tendon under USS guidance would necessitate a 5mm incision and may be performed under local anaesthetic as an out-patient. The current study thus plans a randomised clinical trial to compare outcomes (VISA-A scores and ultrasound tissue characterisation scans) from patients with NIAT undergoing plantaris release using an open surgical procedure with those undergoing a minimally invasive US guided procedure. The former is known to provide good clinical outcomes; however the latter could significantly reduce post-operative scarring, recovery times and costs. Findings will ensure ethical, quality and cost effective patient care.
With this project the investigators wish to: 1. Test the reproducibility of Amlang's ultrasound classification by examining the intra- and inter-rater reliability. 2. Investigate whether Amlang's ultrasound classification is able to predict which patients are likely to develop complications when treated non-operatively. 3. Investigate whether Barfod's length measurement is able to predict which patients are likely to develop complications when treated non-operatively.
Chronic pain and disability are unfortunately common in Achilles tendon pain. Outcome after surgery is often poor. Also tendon pain can be resistant to treatment and may lead to cessation of hobbies or careers. Recently eccentric exercise (defined as muscle loading where tension develops as physical lengthening occurs) has become a cornerstone in managing tendon pain due to an increasing amount of favorable research. Eccentric exercises are considered to be non-invasive, safe, and appear to be important for a successful outcome. One exercise program has been extensively adopted in research and clinical practice for Achilles pain. It recommends individuals perform 180 repetitions a day. However there appears to be little scientific rationale for this number. Consequently there may be significant implications for patient compliance, satisfaction, and overall treatment efficacy in a strategy which is encouraged to be uncomfortable. Fifty two adults (18-70 years old), with mid-Achilles tendon pain will be randomised to standard treatment (180 repetitions) or to a group where individuals are allowed to do what they can. Participants will be recruited from participating physiotherapy departments (health centres and hospital departments) across NHS Forth Valley. All individuals will be required to complete the same type of eccentric exercise for six weeks attending an initial assessment and two follow-up appointments at three and six weeks. Thereafter participants will be discharged if better, or continue with individual care where appropriate. It is hoped this pilot study will establish if future larger scale investigation is warranted examining whether it is necessary to subject individuals to 180 repetitions a day in an activity recommended to be uncomfortable. Also will participant satisfaction differ between exercise groups? If further investigation is warranted this pilot may provide population specific data for future sample size calculations, and may provide a suitable methodology for such investigations.
