Summary
A new Functional Strength Measurement for children with cerebral palsy (CP) is feasible, reliable, and valid. This tool aids in the physical examination of children with CP.
Area of Science:
- Pediatrics
- Neurology
- Rehabilitation Medicine
Background:
- Children with cerebral palsy (CP) lack a standardized tool to measure functional strength across both upper and lower extremities.
- Existing assessment methods may not adequately capture the functional strength deficits specific to CP.
- The development of a specialized instrument is crucial for effective clinical practice and rehabilitation planning.
Purpose of the Study:
- To evaluate the feasibility, test-retest reliability, and validity of the Functional Strength Measurement for Children with Cerebral Palsy (FSM-CP).
- To establish a reliable and valid instrument for assessing functional strength in pediatric CP populations.
- To provide a practical tool for clinicians examining children with CP.
Main Methods:
- The study involved thirty-seven children diagnosed with cerebral palsy (CP), aged 4-10 years, classified under Gross Motor Function Classification System (GMFCS) levels I and II.
- The Functional Strength Measurement for Children with Cerebral Palsy (FSM-CP) underwent standardization of items, with one item removed based on common CP-related compensations.
- Test-retest reliability was assessed, and convergent validity was determined by correlating FSM-CP scores with isometric muscle strength measured using a handheld dynamometer (HHD).
Main Results:
- The FSM-CP demonstrated high test-retest reliability across all measured items, with intra-class correlation coefficients (ICCs) ranging from 0.79 to 0.95.
- Significant correlations were found between the FSM-CP and handheld dynamometer (HHD) measurements, with correlation coefficients (r) ranging from 0.36 to 0.75.
- These findings indicate a strong agreement between the new functional measure and objective strength assessments.
Conclusions:
- The Functional Strength Measurement for Children with Cerebral Palsy (FSM-CP) is a feasible, reliable, and valid tool for use in this population.
- The FSM-CP can be effectively integrated into the clinical practice for the physical examination of children with CP.
- This instrument offers a valuable addition to the assessment repertoire for pediatric rehabilitation specialists.

01:29Reliability and Validity
14.0K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Binary Acids and Bases
In the absence of any leveling effect, the acid strength of binary compounds of hydrogen with nonmetals (A) increases as the H-A bond strength decreases down a group in the periodic table. For group 17, the order of increasing acidity is HF < HCl < HBr < HI. Likewise, for group 16, the order of increasing acid strength is H2O < H2S < H2Se < H2Te. Across a row in the periodic table, the acid strength of binary hydrogen compounds increases with increasing...

01:20Strength of Cement

Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...

01:30Relation Between Tensile Strength and Compressive Strength of Concrete
685
Concrete is a fundamental building material, and understanding its strengths is crucial for construction projects. The relationship between its tensile and compressive strengths is intricate, showing that while these strengths are related, they do not increase at the same rate. Tensile strength's growth is slower and is affected by various factors such as the methods used for testing, the size and shape of the specimen, the texture of the aggregate used, and the moisture content of the...

Distribution reliability in electrical power systems is critical for ensuring an uninterrupted power supply to consumers at minimal cost. According to IEEE Standard Terms, reliability is the probability that a device will function without failure over a specified time period or amount of usage. For electric power distribution, this translates to maintaining continuous power supply and addressing customer concerns over power outages. Several indices, as defined by IEEE Standard 1366-2012, are...
