Case-controlled animal study. ⋯ Results confirmed slow muscle fiber loss in the multifidus in the chronic phase of IVD degeneration induced spontaneously and by injury. Whole-body PA did not attenuate changes to muscle fiber distribution. More specific approaches to muscle activation might be required to achieve more complete reversal of muscle fiber changes, with potential implications for therapy in humans.Level of Evidence: N/A.

Randomized Controlled Trial
A Comparative Study of A Novel Postural Garment Versus Exercise for Women with Nonspecific Cervical Pain: A Randomized Cross-Over Trial.
Randomized cross-over study. ⋯ In our study, PosturePlusForce showed, at least, a similar effect on pain to exercise, although those with dorsal hyperkyphosis exhibited a greater reduction in pain and related variables with the garment. Pain relievers were less required by those wearing PosturePlusForce than by those performing the exercises.Level of Evidence: 1.

Prospective multicenter study. ⋯ The rate of poor baseline waveform derivation in spine surgery was 2% in our series. This was significantly more likely in high-risk surgery for thoracic lesions and OPLL, and in cases with preoperative severe motor deficit. In such cases, it may be preferable to use multiple modalities for IONM to derive multichannel waveforms from distal limb muscles, including the AH.Level of Evidence: 3.
