This pilot study established a minimally invasive biopsy technique to obtain high-quality MTrP tissue samples to evaluate mitochondrial function via high-resolution respirometry.
Myofascial trigger points (MTrPs) are hyperirritable areas in the fascia of the affected muscle, possibly related to mitochondrial impairment. They can result in pain and hypoxic areas within the muscle. This pilot study established a minimally invasive biopsy technique to obtain high-quality MTrP tissue samples to evaluate mitochondrial function via high-resolution respirometry. Secondary objectives included the safety of the biopsy procedure assessed via clinical wound healing (number of patients with signs for local infection and inflammation). For this purpose, twenty healthy males participated in this study, 10 with a diagnosis of myofascial pain in the musculus (m.) trapezius MTrP (TTP group) and 10 with a diagnosis of myofascial pain in the m. gluteus medius (GTP group). The affected muscle was biopsied followed by a biopsy from the vastus lateralis to be used as a control. Measurements of oxygen consumption were carried out using high-resolution respirometry.

A symptom complex characterized by pain and weakness in SKELETAL MUSCLE group associated with exercise, such as leg pain and weakness brought on by walking. Such muscle limpness disappears after a brief rest and is often relates to arterial STENOSIS; muscle ISCHEMIA; and accumulation of LACTATE.
An aggressive THYROID GLAND malignancy which generally occurs in IODINE-deficient areas in people with previous thyroid pathology such as GOITER. It is associated with CELL DEDIFFERENTIATION of THYROID CARCINOMA (e.g., FOLLICULAR THYROID CARCINOMA; PAPILLARY THYROID CANCER). Typical initial presentation is a rapidly growing neck mass which upon metastasis is associated with DYSPHAGIA; NECK PAIN; bone pain; DYSPNEA; and NEUROLOGIC DEFICITS.
