Hand Kit (Grip & Pinch Dynamometer)

The E-LINK Hand Kit which includes a Hand Grip Dynamometer and Pinchmeter for monitoring grip and pinch strength, is the ideal module to quantify and monitor the effectiveness of various interventions for the upper extremity, throughout the whole rehabilitation process.

The Hand Kit can also be used with the E-LINK Activities (Games), for innovative isometric grip and pinch exercises that are totally focused on the individual patient.

Hand Grip Dynamometer For Assessing Grip Strength

The Hand Grip Dynamometer easily and accurately measures a patient's grip strength from 0.1kg/lb measurement through to a maximum of 90kg (200lbs), covering those with chronic debilitating conditions, such as rheumatoid arthritis, as well as those with acute hand injuries.

The following tests, using the Hand Grip Dynamometer with E-LINK software, can be carried out quickly and accurately and include assessments that cannot be undertaken with a manual device:

Standard Peak Force Grip Test (1/4)

Standard Peak Force Grip Test

Three measurements can be quickly entered for each hand position as required. The software automatically calculates the average grip and the coefficient of variation percentage as an indication of the measurement consistency. A force distribution graph is displayed for the five positions.

Sustained Grip Test (2/4)

Sustained Grip Test

This test measures force over time for a 5, 10, 15 or 30 sec interval. Peak force, time to reach peak force, average to peak ratio percentage (sustainability) and fatigue rate are automatically calculated and immediately displayed. The current graph can be compared with a prior test to analyze progress.

Rapid Exchange Grip Test (3/4)

Rapid Exchange Grip Test

Undertaken for the detection of sub-maximal effort, this test is easily performed and documents the grip force applied for eight tests of each hand with a 1, 1.5 or 2 sec interval set timing. The results are displayed in both graph and table form for immediate analysis.

Progress Reports (4/4)

Progress Reports

Progress Reports can be readily generated covering a maximum of 10 tests and the data is displayed in both graph and table format. Automatic calculations show the percentage of change from one session to another, the percentage of change from the first test and the percentage comparison to standard, normative Jamar data for both pediatric and adult values. Ideal as an Outcome Measure and for a Discharge Summary.

Pinchmeter For Assessing Pinch Strength

The Pinchmeter easily and accurately measures a patient's pinch strength from 0.1kg/lb measurement through to a maximum of 22kg (50lbs).

It has a unique, low profile design that permits measurement to be undertaken at a point closer to the end range than any other Pinchmeter device, either manual or electronic.

The software quickly and easily records the following:

Standard Peak Force Pinch Test (1/3)

Standard Peak Force Pinch Test

This test can be taken for the key (lateral), three jaw (tri-pod) and tip to tip positions. Three trials per position can be recorded and the software automatically calculates the average Pinch measurement and the co-efficient of variation percentage as an indication of the measurement consistency. Single measurements of Thumb to Digit Opposition can also be entered for each digit.

Sustained Pinch Test (2/3)

Sustained Pinch Test

This test measures force over time for a 5, 10, 15 or 30 sec interval. Peak force, time to reach peak force, average to peak ratio percentage (sustainability) and fatigue rate are automatically calculated and immediately displayed. The current graph can be compared with a prior test to analyze progress.

Progress Reports (3/3)

Progress Reports

Progress Reports can be easily generated covering a maximum of 10 tests and the data is displayed in both graph and table format. Automatic calculations show the percentage of change from one session to another and the percentage of change from the first test. These Reports are ideal as an immediate clinical Outcome Measure and for Discharge Summaries.

Isometric Grip and Pinch for Exercise

As opposed to traditional zero to peak force exercises, the range of force may be graded, setting the minimum and maximum, to meet the patient's functional goals. Force ranges for exercise are set in 0.1 increments with a maximum load of 90 Kg (200 lbs) for grip and 22 Kg (50 lbs) for pinch. The movement of the objects in the E-LINK Activities is controlled by the application and relaxation of isometric grip or pinch within the set parameters. The various activities provide purposeful activity, isometric strengthening, motor learning and control.

The range of force settings and activities allow multiple exercise options such as:

  • Zero to peak force exercise, taking the patient from full relaxation to maximum, including the option to hold at peak force
  • Exercise within patient limitations, setting the minimum at greater than zero, causing the patient to sustain the pinch or grip and control the force application and relaxation
  • Setting the force range very low allows controlled purposeful activity while minimizing joint loading. This is useful for patients with arthritis and other situations where low force on the joints is desirable
  • Patients with spasticity can work on controlled relaxation within therapist-defined ranges
  • By varying the range of force and time, the patient's rehabilitation can be oriented to specific job or ADL goals
  • Hand Grip Dynamometer (G200)
  • Pinchmeter (P200)
  • Grip and pinch strength evaluation and exercise software

The Hand Kit (H500) requires either the wireless Dongle (DG1) with wireless Adapter (AD1) OR the wired X4 InterX Unit as the interface to the computer.
