The E-LINK Hand Kit which includes a 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.

The Hand Kit (H500) is available with either a wireless or wired interface to the computer.

Grip and Pinch Strength for Evaluation

Biometrics' computerised tools for strength evaluation measure in 0.1 increments (Kg or lbs) and include tests that cannot be done with manual devices. In addition to speeding up data collection, they are extremely sensitive providing accurate measurement on very weak or debilitated patients.

Dynamometer

The precision Biometrics' Dynamometer linked to the E-LINK software easily and accurately measures grip strength:

  • Standard peak force grip test with automatic calculation of average and coefficient of variation
  • Sustained grip test measures force over time in 5, 10, 15, and 30 sec intervals and calculates peak force, time to peak, average, and fatigue rate. Graphically compare the current test with a prior session
  • Rapid exchange grip test, for detection of sub-maximal effort, is easily performed and the results documented in both graph and table form
  • Progress reporting over multiple sessions, in both graph and table form, with calculation of percentage change from session to session, and comparison with standard Jamar normal values (adult and pediatric normal values included)

Pinchmeter

The unique low profile design of the Biometrics' Pinchmeter allows measurement and exercise at closer to end range than any other device - manual or electronic. The software accurately and easily measures pinch strength:

  • Key (lateral), three jaw (tri-pod), tip to tip – three trials per position, calculates average and co-efficient of variation
  • Thumb to digit opposition
  • Sustained pinch test measures force over time in 5, 10, 15, and 30 sec intervals and calculates peak force, time to peak, average, and fatigue rate. Graphically compare the current test with a prior session
  • Progress reporting over multiple sessions, in both graph and table form, with calculation of percentage change from session to session

Unique 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
  • 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 X4 InterX Unit as the interface to the computer.
