The phrase "a left rotation" is correct and usable in written English.
It can be used in contexts related to mathematics, computer science, or any situation where a directional change is being described.
Example: "To balance the binary tree, we need to perform a left rotation on the node."
Alternatives: "a left turn" or "a counterclockwise rotation".
For instance, here is a Caesar cipher using a left rotation of three places, equivalent to a right shift of 23 (the shift parameter is used as the key): Plain: ABCDEFGHIJKLMNOPQRSTUVWXYZ Cipher: DEFGHIJKLMNOPQRSTUVWXYZABC When encrypting, a person looks up each letter of the message in the "plain" line and writes down the corresponding letter in the "cipher" line.
For example, the facet joint forces at levels L2/L3 to L4/L5 in the right joints under a left rotation moment of 5 Nm differed considerably from those at the corresponding levels in the same joints under right rotation.
Furthermore, if the lumbar spine was loaded by a left rotation moment, the right (opposite) joint had a larger facet force than the ipsilateral (left) joint at the corresponding level (contrast Figure 7(a) with Figure 7(b); contrast Figure 7(c) with Figure 7 d), etc)., and vice versa for the case of right rotation (contrast Figure 8(a) with Figure 8(b); contrast Figure 8(c) with Figure 8(d), etc).
[ 27] * The active range of movement in flexion, extension, right and left rotation and right and left lateroflexion of the cervical spine with the patient in a seated position will be measured by the research assistant with the CROM-device.
While maintaining the secondary levers, the therapist performed a single HVLA thrust manipulation to the right atlanto-axial joint using the combined primary thrusting levers of left rotation in an arc toward the underside eye and translation toward the table [ 5, 6, 35].
Active neck mobility: total CROM including flexion, extension, right and left lateral-flexion and right and left rotation was assessed with a CROM device as formerly described.
Here, ⋘ is a left circular rotation.
If filament sliding was possible, the applied torque would impose a left handed rotation to the thin filament, matching the observation in vitro [84].
Thoracic kyphosis (TK), lumbar lordosis (LL), and active spinal range of motion (ROM), in particular flexion-extension, right and left inclination, and right and left rotation, were evaluated by means of a validated pocket compass needle goniometer (IncliMed, Patent no. 0001331516, University of Padua) [ 33, 34].
After an active submaximal range cervical flexion-extension and right and left rotation, patients will be instructed to relocate back to the neutral position.
The HVLA group showed only the change in left rotation from initial to final consultations and from initial consultation to 1-month follow-up to be statistically significant.
