GRIP DYNAMOMETER
• Grip strength is a measure of muscular strength or the maximum force/tension generated by one’s forearm muscles. It can be used as a screening tool for the measurement of upper body strength and overall strength.
• The purpose of using a grip dynamometer is to measure isometric strength of the hand and forearm muscles. The grip dynamometer can be adjusted for hand size and must be calibrated regularly for consistent results. Having clear protocols regarding technique in the administration of the test will also ensure reliability.
• The subject holds the dynamometer in the hand being tested, with the arm at right angles with the elbow by the side of the body. Adjusting the handle of the dynamometer as necessary, making sure that the base rests on the first metacarpal ( heel of the palm), while the handle rests on the middle of the four fingers. The subject then squeezes the grip dynamometer with maximum isometric effort for atleast 5 seconds. The subject will do several trials of the test, resting for 15 seconds between each test. The subject is required to not move any other part of the body and is encouraged to use maximum effort. The best result of each trial is the one that is recorded.
• Grip Dynamometer gives a reliable and simple measurement which can be used as a predictor of future health concerns. Its simplicity, cost-effectiveness and time efficiency makes the grip dynamometer a useful tool in any physical therapy clinic.

FINGER DEXTERITY MAZE APPARATUS
• Dexterity refers to the ability of a person to use the fingers,hands and arms to perform a task. The quality of performance in daily living skills,work-related functioning, and recreational activities is determined to a large degree by hand function and manual dexterity. The hand has to be able to undertake extremely fine and sensitive movements and must also be able to perform tasks requiring considerable force.
• Dexterity tests measure the accuracy of hand and finger movements under controlled conditions. They help physical therapists to develop rehabilitation plans for patients and to measure the effectiveness of their programs. They can help identify and evaluate certain forms of brain damage, identify neurologically based learning disabilities, and musculoskeletal disabilities.
• The apparatus consists of a wooden box containing 100 holes. There are pins kept separately to be placed in these holes. While keeping the apparatus on the right side of the subject, he/she is asked to insert pins in the holes with right hand. Time taken and errors committed are noted. Same procedure is repeated with left hand keeping the instrument to the left hand side of the subject.

DIVISION OF ATTENTION BOARD WITH RESET 6 DIGIT IMPULSE COUNTER
(2)
• Divided attention could be defined as our brain’s ability to attend to two different stimuli at the same time, and respond to the multiple demands of your surroundings. Divided attention is a type of simultaneous attention that allows us to process different information sources and successfully carry out multiple tasks at a time. This cognitive skill is very important, as it allows us to be more efficient in our day-to-day lives.
• Our ability to attend to multiple stimuli and do various tasks at a time does have its limits. When you divide your attention, the efficiency with which you do these actions is decreased, and you will almost certainly perform poorly. Interference is the term used to describe when a person has a hard time attending to two stimuli at a time. We see interference when the brain is only able to process a certain amount of information. However, cognitive training can help improve divided attention, and as a consequence, the ability to do more than one activity at a time.
• The apparatus consists of a wooden board with a circular and triangular groove with a metallic contact point on each. The board is wired so that any passage of electric current on it from a battery can be indicated by an impulse counter.
• The board is connected to a battery terminal. The other terminal of the battery is connected to a metallic stylus through the impulse counter. Whenever the stylus touches the metallic contact point, the impulse counter records it as an error.

COLOUR PREFERENCE APPARATUS
• In the Psychology of colour, colour preferences are the tendency for an individual or a group to prefer some colours over others, such as having a favorite colour or a traditional colour. This is the idea that the preference for colour is determined by the average affective response to everything the individual associates with the colour. Hence, positive emotional experiences with a particular colour are likely to increase the propensity to develop a preference for that colour and vice versa.
• Its a Psychological test based on the idea that personality traits can be identified by the color preferences of any individual.
• Colour Preference on the basis of paired comparison method (6 colours) where participants choose the colour they like more than another colour presented simultaneously.
• The apparatus comes with a manual.
