Summary
Grip strength in stroke survivors significantly improves within the first year, with most gains occurring in the initial six months. This recovery trajectory is consistent across various grip strength assessments.
Area of Science:
- Neurology
- Rehabilitation Medicine
- Biomedical Engineering
Background:
- Stroke frequently results in impaired grip strength, impacting daily function.
- Understanding grip strength recovery is crucial for effective post-stroke rehabilitation strategies.
Purpose of the Study:
- To evaluate the recovery patterns of grip strength in the first year following a stroke.
- To quantify grip strength, rate of force development, and grip sustainability in stroke survivors.
Main Methods:
- An exploratory study involving 11 patients with mild to moderate stroke.
- Grip and pinch strength were assessed using an electronic dynamometer at 5 intervals over one year.
- Measurements included maximum grip force, rate of force development, and grip sustainability.
Main Results:
- Affected hand grip force improved significantly within the first year, primarily in the first six months.
- Early deficits (2-4 weeks) in force development and sustainability were substantial compared to the non-affected hand.
- Grip strength approached non-affected hand levels by six months, with minimal further improvement by one year.
Conclusions:
- Grip strength shows considerable recovery in the first year post-stroke.
- The recovery pattern is characterized by rapid initial improvement followed by slower gains.
- These findings inform rehabilitation timing and expectations for grip strength recovery.

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
666
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...

01:29Strength and Heat of Hydration
680
The hydration of cement is an exothermic reaction in which heat is generated as cement hydrates. This heat of hydration is critical to cement's strength development. The rate at which this heat is generated affects the temperature rise, with a majority of the heat being released early in the hydration process, half within the first three days, and about 75% within the first week.
The heat of hydration for each cement compound is significant; for instance, tricalcium aluminate (C3A) and...

01:22Fatigue Strength of Concrete
559
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...
