+# Twente Lower Extremity Model v.1.2
+
+
+:::{deprecated} 2.5.0
+TLEM 1 has been deprecated.
+:::
+
+
+The AnyBody implementation of a the Twente lower extremity model (TLEM) consists
+of **159 muscles**, and **6 joint degrees**.

+% .. centered:: *Twente Lower Extremity Model (version 1.2)*
+
+The model has been validated against ‘state of the
+art’ literature with respect to its biomechanical performance and first
+applications in gait and cycling deliver very convincing results.
+
+The model is based on published morphological consistent anatomical
+dataset on muscle and joint parameters by Martijn Klein-Horsman from the
+University of Twente, The Netherlands. The implementation of the model
+was started by Karin Gorter, a Master Student, also from the University
+of Twente, during a three-month stay at Aalborg University and has been
+finished by the AnyBody Technology.
+
+The current version has been updated several times and is still being
+maintained in collaboration with The AnyBody Research Group at Aalborg
+University (DK) (www.anybody.aau.dk) and University of Twente (NL) under
+the TLEMsafe project ([www.tlemsafe.eu](https://tlemsafe.eu/)).

+## Example Configuration

+muscle model and only one leg:
