Baseline Finger Goniometer, Plastic, Flexion and Hyperextension

The Baseline Finger Goniometer is a clear plastic instrument designed for accurate range-of-motion measurement of the finger joints, including the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints. The measurement range covers 30 degrees of hyperextension through 120 degrees of flexion, accommodating the full functional ROM of the finger in a compact, easy-to-use design. Clear plastic construction allows direct visualization of the joint axis during measurement for precise alignment.

Ideal For

Physical therapists and occupational therapists who perform hand and finger ROM assessments as part of upper extremity evaluation, post-surgical follow-up, or hand therapy programs will find the Baseline finger goniometer a compact and accurate tool for measuring MCP, PIP, and DIP joint motion. Hand therapists and certified hand therapists (CHTs) who document finger ROM for baseline assessment, progress tracking, and functional outcome measurement will find the 30-degree hyperextension to 120-degree flexion range covers the full clinical measurement spectrum for finger joints. Orthopedic surgeons, hand surgeons, and occupational medicine physicians who measure finger ROM in post-operative or post-injury evaluations will find the clear plastic construction supports accurate joint axis alignment during assessment. Occupational therapy students and physical therapy students learning goniometric measurement of finger joints will find this a standard-format instrument appropriate for clinical skills training.

Frequently Asked Questions

What joints can this finger goniometer measure?
This goniometer is designed for the metacarpophalangeal (MCP), proximal interphalangeal (PIP), and distal interphalangeal (DIP) joints of the fingers. It is sized and scaled for the small range of motion measured at these joints, making it more accurate for finger assessment than a standard full-size goniometer.

What does the hyperextension range mean?
Hyperextension refers to movement of the finger beyond the neutral (0-degree) position in the direction opposite to flexion. Some individuals, particularly those with hypermobility, can extend their finger joints past neutral. The 30-degree hyperextension range on this goniometer allows the clinician to measure and document this range accurately rather than recording it as zero.

How is a finger goniometer different from a standard goniometer?
A standard goniometer has longer arms suited to larger joints such as the knee, hip, or shoulder. A finger goniometer has shorter arms and a smaller head scaled to the size of finger joints, allowing more accurate placement over the small joint surface and more precise alignment with the joint axis during measurement.

How do I clean the finger goniometer?
Wipe down with a damp cloth and mild disinfectant between patient uses, following your facility's infection control protocols. Avoid harsh solvents that may cloud or damage the clear plastic. Store flat to prevent warping of the arms.
