Effect of Ulnar-Based Orthotics and Strengthening Exercises on Subjects With Ulnar Wrist Pain
Context:
In comparison with the published research on the surgical management of ulnar wrist pain, fewer studies that discuss the nonsurgical management of ulnar wrist pain exist.
Objective:
The purpose of this pilot study was to investigate the effect of ulnar-based wrist orthotics and strengthening exercises on subjects with ulnar wrist pain.
Study Design:
Prospective randomized controlled pilot study.
Setting:
Research laboratory.
Participants:
Thirty subjects with acute and subacute ulnar wrist pain and age ranging from 18 to 53.
Interventions:
Participants were randomized to receive either ulnar-based orthotics, ulnar-based orthotics plus strengthening exercises, or placebo intervention.
Main Outcome Measures:
The authors measured pain and function using the Patient-Rated Wrist Evaluation questionnaire, and grip strength using the JAMAR dynamometer, at baseline and at 2- and 4-week postrandomization. A mixed analysis of variance modeling was used to investigate the effect of the intervention over time.
Results:
There were statistically significant differences between the 2 intervention groups and the control group regarding improvement in pain, function, and strength, whereas there were no statistically significant differences between the 2 intervention groups over the 3 measurement occasions regarding the outcome measures.
Conclusion:
Based on the results, orthotics intervention is as effective as orthotics plus strengthening exercises in improving pain, function, and grip strength in subjects with ulnar wrist pain.
Level Of Evidence:
Therapy, level 2b individual Randomized Controlled Trial.

Exercise Stress Test
Exercise stress testing, commonly known as a treadmill test, is a noninvasive procedure used to evaluate cardiovascular function and diagnose heart conditions.
Definition
An exercise stress test measures the heart's response to exertion using a treadmill or stationary bicycle. Chest electrodes record the heart's electrical activity through an ECG, and blood pressure is monitored regularly.
Purposes
Cable Subjected to Its Own Weight
A generalized loading function is employed to analyze a cable subjected to its own weight. This function considers the force acting along the cable's arc length rather than its projected length, providing a more accurate...
Exercise and Muscle Performance
Endurance exercises
Endurance exercises involve running, swimming, or cycling, which require repetitive movements with low force output. When a person engages in endurance exercise, a few noticeable changes occur in their skeletal muscles. For instance, the number of capillaries...
Exercise and Cardiac Output
Sustained exercise increases the muscles' oxygen demand, which can be...
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
