Chiropractors use drop tables because the dropping mechanism does part of the work for them, reducing the amount of manual force needed to move a joint. The table absorbs and redirects energy so the chiropractor can make adjustments that are faster, more targeted, and more comfortable for the patient. This technique, formally called the Thompson Terminal Point Technique, has been a staple in chiropractic offices for decades.
How a Drop Table Works
A drop table looks like a standard chiropractic table, but individual sections are built on spring-loaded hinges that can be raised slightly, usually less than an inch. The chiropractor sets the tension on a specific section, positions their hands over the target area, and delivers a quick thrust. The moment force is applied, that section of the table drops, falling a short distance before stopping abruptly.
That sudden stop is the key. When the table segment drops and hits its endpoint, the patient’s body briefly continues moving downward due to inertia. This creates a separation force at the targeted joint without the chiropractor needing to push as hard. Gravity and the table’s mechanism handle a significant portion of the work. The result is a precise adjustment delivered with less physical effort from the practitioner and less impact felt by the patient.
Separate Segments for Different Areas
Drop tables aren’t one-size-fits-all platforms. They’re divided into independent sections that correspond to regions of the spine: the cervical (neck), thoracic (mid-back), lumbar (lower back), and pelvic segments. Each section can be raised and triggered independently, which lets the chiropractor isolate a single area with precision.
This segmental design is especially useful for adjustments at the lumbar-sacral junction, where the lower spine meets the pelvis, and for pelvic corrections involving the sacroiliac joints. These areas often require careful, targeted force. Having a dedicated drop section for the pelvis means the chiropractor can address that region without affecting neighboring segments of the spine.
Why Less Force Matters
Traditional manual adjustments rely almost entirely on the chiropractor’s hands and body weight to move a joint through its restricted range. That works well for many people, but it’s not always ideal. Some patients are uncomfortable with the amount of pressure involved, and others have conditions that make a high-force approach risky or simply unnecessary.
Drop tables allow chiropractors to deliver effective adjustments with noticeably less manual force. The table’s drop mechanism supplements the thrust, so the chiropractor doesn’t need to generate as much power on their own. This makes the technique a gentler option for older adults, people recovering from injuries, patients with osteoporosis or inflammatory conditions, and anyone who tenses up during traditional hands-on adjustments. That tension, by the way, can actually make a manual adjustment harder to perform and less effective, so a method that reduces the patient’s guarding response has a real practical advantage.
The Leg Length Check
Chiropractors who use the Thompson technique typically begin with a specific diagnostic step called the Derifield-Thompson test. The patient lies face down on the table, and the chiropractor compares the apparent length of both legs. Subtle differences in leg length can signal misalignment in the pelvis or spine, because when joints shift out of their normal position, it can cause one leg to appear slightly shorter than the other.
Trained practitioners can reliably detect leg length differences of less than 3 millimeters using this method. The chiropractor may also turn the patient’s head to different positions and recheck, since rotating the cervical spine can change the leg length reading and help pinpoint where the problem originates. After the adjustment, the leg check is repeated to see whether the difference has resolved, serving as a built-in way to evaluate results in real time.
What the Experience Feels Like
If you’ve never been on a drop table, the experience is straightforward. You lie face down, and the chiropractor raises the relevant section of the table beneath the area being treated. You’ll hear a mechanical click when the section is set. The chiropractor then places their hands on the target area and delivers a quick push. The table section drops with a noticeable but brief sound and motion, similar to a firm tap.
Most people find it less jarring than a traditional adjustment. There’s no twisting of the body into unusual positions, and the popping or cracking sounds that accompany some manual techniques are less common with drop table work. The entire adjustment for a single area takes only a second or two, though your chiropractor may address multiple segments in one visit.
Who Benefits Most
Drop tables are versatile enough for routine spinal adjustments on healthy adults, but they particularly shine for patients who need a modified approach. People with limited mobility, whether from arthritis, recovering from surgery, or dealing with acute pain, often tolerate drop table adjustments better than traditional manual techniques. Pregnant patients sometimes prefer this method because they can lie comfortably on the table without the rotational positioning that other techniques require.
Chiropractors also find drop tables useful when treating areas that are difficult to adjust manually, like the mid-thoracic spine, where the rib cage limits how much leverage a practitioner can generate with their hands alone. The table’s assist makes these adjustments more achievable without requiring excessive force. For practitioners themselves, drop tables reduce the physical strain of performing adjustments all day, which can help prevent repetitive stress injuries over a long career.
