EMG at Performing ULTN 1 in Breast Cancer Patients
- Conditions
- Physiotherapy
- Interventions
- Other: ULNT 1 and EMG recording
- Registration Number
- NCT02599467
- Lead Sponsor
- University of Alcala
- Brief Summary
Upper limb neural mechanosensitivity is a painful disturbance that breast cancer patients often undergo following axillary surgery. It is assessed by the upper limb neurodynamic test for the median nerve, called upper limb neurodynamic test 1 (ULNT1). Design: A matched case-control observational study. Objective: to check the increased upper limb mechanosensitivity by shoulder range of motion (ROM) during ULNT1 and to determine, for the first time, the evoked electromyographic (EMG) muscle activity. Participants: 62 cases who underwent breast cancer surgery and 64 matched control women. Setting: Torrejon Hospital, Physical Therapy Department, Madrid (Spain). Intervention: To record EMG muscle activity during ULNT1 performance and to measure shoulder ROM. Key outcomes: mechanosensitivity, breast cancer, pain, EMG, shoulder ROM, median nerve.
- Detailed Description
Upper limb neural mechanosensitivity is a painful disturbance that breast cancer patients often undergo following axillary surgery. It is assessed by the upper limb neurodynamic test for the median nerve, called upper limb neurodynamic test 1 (ULNT1).A neural provocation test is a sequence of movements designed to assess the mechanics and physiology of part of the nervous system by elongating the length of the nerve bedding and by increasing the pressure in and around the peripheral nerve .The most reliable test to assess the upper limb neural mechanosensitivity is the neural provocation test for the median nerve, called upper limb neurodynamic test 1 (ULNT1). This test consists of depressing shoulder girdle in a neutral position, shoulder abduction and lateral rotation, elbow extension, forearm supination and wrist extension. Cervical contralateral lateral flexion may be included to further increase the loading of the brachial plexus and, as a sensitizing maneuver, to differentiate structurally between neural and non-neural involvement. The ULNT1 is considered as positive when symptoms are reproduced on affected upper limb, or side-to-side differences in ROM, or symptoms modified by lateral neck side-bending. Likewise, It is also necessary to assess the EMG activity of the involved muscles to verify the early and increased protective muscle response suggested throughout the neural strain performance.
