{"product_id":"baseline-extendable-goniometer-chromium-brass-4x-lens","title":"Baseline Extendable Goniometer, Chromium Brass, 4X Lens","description":"\u003cp\u003eThe Baseline Extendable Goniometer is constructed of chromium-plated brass with two stainless steel arms that extend from 9 to 26 inches to accommodate measurement of both small and large joints in a single instrument. The 4X magnifying lens makes the dual 180-degree high-resolution scale easy to read with precision. The 360-degree arm rotation in both directions with a resistance swivel ensures the arms stay in position during measurement without slipping. Compact, lightweight, and portable for clinical and field use. Total extended length: 22-1\/4 inches.\u003c\/p\u003e\n\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e4X magnifying lens for easy, accurate reading of the dual 180° high-resolution scale\u003c\/li\u003e\n  \u003cli\u003eDual 180-degree scale with high-resolution markings for precise measurement\u003c\/li\u003e\n  \u003cli\u003eStainless steel arms extending 9 to 26 inches for small and large joint measurement\u003c\/li\u003e\n  \u003cli\u003eChromium-plated brass construction — durable, corrosion-resistant, and precise\u003c\/li\u003e\n  \u003cli\u003e360-degree arm rotation in both directions for full range of motion measurement\u003c\/li\u003e\n  \u003cli\u003eResistance swivel holds arms in position during measurement without slipping\u003c\/li\u003e\n  \u003cli\u003eSmooth precision glide for consistent, repeatable measurements\u003c\/li\u003e\n  \u003cli\u003eTotal extended length: 22-1\/4 inches\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eSKU: 10047D\u003c\/li\u003e\n  \u003cli\u003eBrand: Baseline\u003c\/li\u003e\n  \u003cli\u003eConstruction: Chromium-plated brass body, stainless steel arms\u003c\/li\u003e\n  \u003cli\u003eArm Range: 9 to 26 inches\u003c\/li\u003e\n  \u003cli\u003eTotal Extended Length: 22-1\/4 inches\u003c\/li\u003e\n  \u003cli\u003eScale: Dual 180-degree high-resolution\u003c\/li\u003e\n  \u003cli\u003eLens: 4X magnifying\u003c\/li\u003e\n  \u003cli\u003eRotation: 360 degrees, both directions\u003c\/li\u003e\n  \u003cli\u003eSwivel: Resistance swivel for arm stability\u003c\/li\u003e\n  \u003cli\u003eShipping Carton: 9 x 7 x 5 inches\u003c\/li\u003e\n  \u003cli\u003eCountry of Origin: China\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eIdeal For\u003c\/h3\u003e\n\u003cp\u003ePhysical therapists and occupational therapists who measure joint range of motion across a variety of patient populations will find the extendable arms — ranging from 9 to 26 inches — allow accurate alignment on both small joints such as fingers and wrists and large joints such as the hip, knee, and shoulder with a single instrument. Orthopedic and sports medicine clinicians conducting ROM assessments and documenting rehabilitation progress will find the resistance swivel and 4X magnifying lens support repeatable, precise readings. Home health practitioners and clinicians who perform field assessments will find the compact, lightweight, portable design practical for use outside the clinic. DME suppliers and physical therapy programs stocking goniometers for clinical or educational use will find the chromium-plated brass construction a durable option for high-volume use.\u003c\/p\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is a goniometer and how is it used?\u003c\/strong\u003e\u003cbr\u003e\nA goniometer is a clinical instrument used to measure the range of motion of a joint in degrees. The clinician aligns the stationary arm with the proximal body segment and the moving arm with the distal body segment, with the axis centered over the joint. The angle between the two arms is read from the scale. Goniometry is a standard assessment tool in physical therapy, occupational therapy, and orthopedic medicine.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhy does this goniometer have extendable arms?\u003c\/strong\u003e\u003cbr\u003e\nExtendable arms allow the same instrument to accurately align with bony landmarks on both small joints and large joints where landmarks are far apart. The arms on this goniometer extend from 9 to 26 inches, eliminating the need to carry multiple goniometers of different sizes.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat does the 4X magnifying lens do?\u003c\/strong\u003e\u003cbr\u003e\nThe 4X magnifying lens enlarges the degree markings on the scale, making it easier to read precise measurements without approximating. This is particularly useful for high-resolution scales where 1 to 2 degree precision is important for documenting ROM changes over the course of rehabilitation.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eWhat is the resistance swivel and why does it matter?\u003c\/strong\u003e\u003cbr\u003e\nThe resistance swivel provides friction at the pivot point to hold the arms in position after they are set, preventing them from slipping before the reading is taken. This allows the clinician to position the arms on the patient, lift the goniometer, and read the scale accurately without the arms shifting during the process.\u003c\/p\u003e","brand":"Baseline","offers":[{"title":"Default Title","offer_id":40388468015158,"sku":"10047D","price":175.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1443\/4772\/products\/complete-medical-goniometers-default-title-extendable-goniometer-chromium-brass-4x-lens-dual-180-degree-scale-23631681421366.jpg?v=1788637171","url":"https:\/\/www.precisionlabworks.com\/en-ca\/products\/baseline-extendable-goniometer-chromium-brass-4x-lens","provider":"Precision Lab Works","version":"1.0","type":"link"}
