***

Fascia lata fasciitis syndrome is caused by inflammation of the fascia lata from overuse or misuse. It is characterized by a dull, aching pain in the lateral hip that radiates into the lateral thigh. The pain is frequently worse on rising and improves with initial activity and then again worsens with continued activity, making walking extremely difficult.

Because it is used for so many movements and is in a shortened position when seated, the TFL becomes tight easily. TFL stretches lengthen this important muscle.^[4]

Strain

A small case notes that “it seems possible that a sloped or banked surface could predispose an individual to a TFL strain.”^[5] In such a case, “treatment usually consists of rest, heat, and flexibility exercises”,^[5] such as lliotibial band stretching.

Etymology

"Tensor fasciae latae" translates from Latin to English as "stretcher of the side band". "Tensor" is an agent noun that comes from the past participle stem "tens-" of the Latin verb "tendere", meaning "to stretch".^[6] "Fasciae" is the Latin term for "of the band" and is in the singular genitive case. "Latae" is the respective singular, genitive, feminine form of the Latin adjective "latus" meaning "side".^[7][8]
