Primary outcome
Ultrasound tissue characterisation echo types
Secondary outcome
standard error of measurement and intraclass correlation coefficient and
dynamic coherence (measure of the change in three-dimensional pennation angle).
Background summary
Ultrasound tissue characterisation (UTC) is a relatively new method that can be
used to determine the structure of tendinous tissue. Previous studies have
shown differences in Achilles and patella tendon structure between individuals
with and without tendinopathy using UTC. No study has investigated whether UTC
can detect differences in tendon structure between individuals with proximal
hamstring tendinopathy (PHT) and individuals without PHT. Further, the
intra-observer reliability of ultrasound tissue characterisation on the
conjoint tendon and intramuscular tendon of the biceps femoris longhead is
unknown. Finally, it is also unknown whether the three-dimensional changes in
fascicle pennation structure during a passive condition and static muscle
contraction can be visualised with this method and whether these changes differ
between individuals with and without PHT.
Study objective
The primary aim of this study is to investigate the feasibility of using UTC to
detect differences in proximal hamstring tendon structure between individuals
with and without clinically diagnosed PHT. A secondary aim is to: 1)
investigate the within-session intra-observer reliability of ultrasound tissue
characterization. Further secondary aims are to compare differences in echo
types between the dominant and non-dominant leg and between the conjoint and
intramuscular tendon of the biceps femoris within legs and investigate
differences in 3D pennation structure as quantified with the *dynamic
coherence* algorithm between passive and active conditions and between
individuals with and without proximal hamstring tendinopathy during passive and
active conditions.
Study design
Cross-sectional study
Study burden and risks
One experimental session of approximately 2 hours. The procedures are
non-invasive and unlikely to lead to injuries or any other discomfort. The
research will not directly benefit the participants, although all participants
get information on the integrity of their tendon, which may be of special
interest for patients with PHT to determine effective treatment.

Inclusion criteria
To be eligible to participate in this study as a participant without PHT, the
participant must meet all of the following criteria:
- Between 18-65 years old;
- Participating in sports that involve running, cycling or strength training
for at least three two times per week.
To be eligible to participate in this study as a participant with PHT, the
participant must meet all of the following criteria:
- Between 18-65 years old;
- Background in, or currently active in a sport that involves running, cycling
or strength training for at least two times per week;
- Clinically diagnosed PHT.
Exclusion criteria
A potential participant who meets any of the following criteria will be
excluded from participation:- Severe visual or hearing impairment since this
makes explanation of the correct position for imaging more difficult;
- BMI outside 18-25, since excessive adipose tissue around the hip region will
make it difficult to get clear images of the hamstrings tendon tissue;
- Known cardiovascular or other diseases;
- In accordance with a previous study13, hypoechoic areas on the tomographic
planes in the 3-D volume of the UTC measurements did not lead to exclusion.For
control participants, the following additional exclusion criteria apply:-
History of a previous injury to the upper leg within the previous 5 years;
- Pain, ache or soreness in the upper leg within the previous year
