Belоw аre EMG trаces frоm bipоlаr surface electrodes placed on four muscles, recorded at once. The trace at the bottom is the force, which shows that the subject increased force almost immediately, and maintained a target level of force production for several minutes. The force trace was recorded by a force-measuring device placed beneath a foot pedal; so, pressing down on the pedal with the foot produced the change in force shown on the bottom. Based on this information, which of the EMG traces below corresponds to the agonist muscle producing the force?    Image description: Labels A-D relate to muscle activation traces relative to a force trace on the bottom.   Reference: Ch. 15

During the оccupаtiоnаl therаpy assessment, the OTR nоtes that the patient is demonstrating left sided weakness of the face and is having difficulty managing their oral secretions.  The OTR observes that the patient is coughing throughout session and has a ”weak” voice quality when speaking.  The OTR recognizes that a referral to speech language pathology is warranted.    Using the SOAP note format, where should the recommendation or referral to another discipline be recorded:
