The Effect of Priming of Questionnaire Content on Grip Strength in Patients With Hand and Upper Extremity Illness

2015-07-10 08:53:23 | BioPortfolio

Summary

Objectives:

To determine the association between priming and measurements of hand function such as grip strength

Primary null hypothesis:

There is no difference in grip strength (best of three attempts) as a percent of the opposite hand between patients that complete the standard Pain Catastrophizing Scale (PCS) compared to patients that complete the positively adjusted PCS.

Secondary null hypotheses:

There is no difference in grip strength (last of three attempts) as a percent of the opposite hand between patients that complete the standard PCS compared to patients that complete the positively adjusted PCS.

There is no difference in grip strength (best of three attempts) before and after completing the questionnaires between patients that complete the standard PCS compared to patients that complete the positively adjusted PCS.

Description

Priming affects all aspects of human behavior. Prior research by the investigators' group determined that completing a positively phrased version of the pain catastrophizing scale (PCS) primed patients to report less disability on average than completing the standard PCS. The influence of priming can be better understood by determining if it also affects direct measurements of hand function such as grip strength measures.

Medical and Biotech [MESH] Definitions

The region of the upper limb in animals, extending from the deltoid region to the HAND, and including the ARM; AXILLA; and SHOULDER.

DEEP VEIN THROMBOSIS of an upper extremity vein (e.g., AXILLARY VEIN; SUBCLAVIAN VEIN; and JUGULAR VEINS). It is associated with mechanical factors (Upper Extremity Deep Vein Thrombosis, Primary) secondary to other anatomic factors (Upper Extremity Deep Vein Thrombosis, Secondary). Symptoms may include sudden onset of pain, warmth, redness, blueness, and swelling in the arm.

A major nerve of the upper extremity. In humans, the fibers of the median nerve originate in the lower cervical and upper thoracic spinal cord (usually C6 to T1), travel via the brachial plexus, and supply sensory and motor innervation to parts of the forearm and hand.

A major nerve of the upper extremity. In humans, the fibers of the ulnar nerve originate in the lower cervical and upper thoracic spinal cord (usually C7 to T1), travel via the medial cord of the brachial plexus, and supply sensory and motor innervation to parts of the hand and forearm.

Scaly papule or warty growth, caused by five fungi, that spreads as a result of satellite lesions affecting the foot or leg. The extremity may become swollen and, at its distal portion, covered with various nodular, tumorous, verrucous lesions that resemble cauliflower. In rare instances, the disease may begin on the hand or wrist and involve the entire upper extremity. (Arnold, Odom, and James, Andrew's Diseases of the Skin, 8th ed, p362)
