Telehealth in Physical Medicine and Rehabilitation: A Narrative Review
Publication date: May 2017 Source:PM&R, Volume 9, Issue 5, Supplement Author(s): Adam S. Tenforde, Jaye E. Hefner, Jodi E. Kodish-Wachs, Mary A. Iaccarino, Sabrina Paganoni Telehealth refers to health care interactions that leverage telecommunication devices to provide medical care outside the traditional face-to-face, in-person medical encounter. Technology advances and research have expanded use of telehealth in health care delivery. Physical medicine and rehabilitation providers may use telehealth to deliver care to populations with neurologic and musculoskeletal conditions, commonly treated in both acute care ...

Transposed firing activation of motor units
Muscles are composed of groups of muscle fibers, called motor units, each innervated by a single motoneuron originating in the spinal cord. During constant or linearly varying voluntary force contractions, motor units are activated in a hierarchical order, with the earlier-recruited motor units having greater firing rates than the later-recruited ones. We found that this normal pattern of firing activation can be altered during oscillatory contractions where the force oscillates at frequencies ≥2 Hz. During these high-frequency oscillations, the activation of the lower-threshold motor units effectively decreases and tha...

What Causes Muscle Weakness?
Discussion Muscle tone is the slight tension that is felt in a muscle when it is voluntarily relaxed. It can be assessed by asking the patient to relax and then taking the muscles through a range of motion such as moving the wrists, forearm and upper arm. Muscle strength is the muscle’s force against active resistance. Impaired strength is called weakness or paresis. There are 5 levels of muscle strength. 0 = No muscle contraction detected 1 = Barely detected flicker of contraction 2 = Active movement with gravity eliminated 3 = Active movement against gravity 4 = Active movement against gravity and some resistance ...
