The Journal of Orthopaedic and Sports Physical Therapy
|January 1, 1986
Summary
The tape measuring method reliably assesses active neck range of motion. This study found it accurate for clinicians, with minimal measurement errors, even for inexperienced testers.
Area of Science:
- Orthopedics
- Physical Therapy
- Biomechanics
Background:
- Accurate measurement of neck range of motion (ROM) is crucial for clinical assessment.
- The tape measuring method is a common technique, but its reliability needs validation.
Purpose of the Study:
- To evaluate the reliability of the tape measuring method for six active neck motions.
- To estimate measurement errors associated with this technique.
- To compare intratester reliability between experienced and inexperienced testers.
Main Methods:
- Seventeen healthy subjects were measured twice for each of six active neck motions by two testers (experienced and inexperienced).
- Intratester reliability was assessed using correlation analysis.
- Measurement errors were estimated using 99% confidence intervals.
Main Results:
- Intratester reliability coefficients ranged from 0.80 to 0.95 for the experienced tester and 0.78 to 0.91 for the inexperienced tester.
- Estimated measurement errors were generally lower for the experienced tester.
- No significant difference in intratester reliability was found between testers for most motions, except extension.
Conclusions:
- The tape measuring method is a reliable tool for clinicians to measure active neck range of motion.
- The method demonstrates good intratester reliability, with minimal differences between experienced and inexperienced testers.

01:18Distance Measurements by Taping
Tapes are essential in surveying for accurate, durable, and short-distance measurements. Made from lightweight, nylon-coated steel, they offer flexibility and strength for rugged outdoor use. The nylon coating protects against rust and wear, extending the tape's life. Standard lengths, around 30 meters, are marked in meters and millimeters for precision.Surveyors select tapes based on site conditions and accuracy needs. Lightweight, nylon-coated tapes are commonly used for ease of handling and...
01:18Errors in Taping
Errors in taping arise from multiple factors that can significantly impact measurement accuracy in surveying. Misalignment of the tape, often due to human error, is one primary source. A skilled rear tapeman, using a telescope, can help correct alignment by guiding the head tapeman; however, human limitations still lead to small inaccuracies. These errors may include misplacement of pins or inaccurate tape readings due to common visual confusions, such as mistaking a six for a nine. Such...
01:12Taping Over Different Ground Profiles
Taping over varying ground profiles requires careful adaptation to achieve accurate measurements. On smooth, level ground with minimal vegetation, the tape can rest directly on the ground. Here, the taping team, typically consisting of a head and a rear tapeman, coordinates their positions with clear communication. The rear tapeman holds the tape at the starting point and guides the head tapeman toward a range pole placed beyond the endpoint, using hand or voice signals to ensure alignment.On...

Here is a stepwise guide to assessing the body temperature at the temporal artery using a temporal artery thermometer
Step 1: Perform hand hygiene and don a fresh pair of gloves to prevent cross-infection and ensure patient safety.
Step 2: Explain the procedure to the patient to establish trust. Clear communication establishes trust with the patient, ensures they understand what to expect, promotes cooperation, and enhances comfort during the procedure.

01:13Equipments Used to Measure Body Temperature
Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

01:14Temperature Measurement Sites
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
