Are there any randomized trials comparing chiropractic to sham or PT?
The short version: yes, such trials exist, but none of the six records in front of me is one of them.
The closest match is a trial that randomized people with low back pain to a single lumbar manipulation or to a sham manipulation, then measured pressure pain thresholds [2]. That is a real sham-controlled randomized comparison, and it found no difference in response between pain trajectories [2]. It is not spinal stenosis, and it is not chiropractic care as a course of treatment. It is one thrust, one session, one outcome.
The other records do not answer the question. One is a retrospective single-arm program with no control group [1]. One randomized trial compares epidural steroid injection plus physical therapy against injection alone, with no chiropractic arm [4]. The rest are a narrative review [5], a spinal cord stimulation case series [6], and a machine-learning disc-herniation paper [3] that has nothing to do with this.
So the honest answer: sham-controlled and PT-controlled trials of spinal manipulation exist in the broader literature, but this retrieval did not surface one in stenosis, and I cannot confirm what any specific trial found. What would settle it is a randomized trial in confirmed stenosis comparing chiropractic manipulation against sham manipulation and against a structured PT program, with walking distance and disability as the outcomes.
My call: the design you are asking about exists for low back pain generally [2], but for spinal stenosis specifically the evidence in front of me does not include it, and I will not pretend a single-thrust LBP trial answers a stenosis question. Confidence: low.

Pressure pain threshold and temporal summation in adults with episodic and persistent low back pain trajectories: a secondary analysis at baseline and after lumbar manipulation or sham
A secondary analysis of a trial compared baseline pressure pain threshold (PPT) and temporal summation (TS) across adults with no low back pain (LBP), episodic LBP, and persistent LBP, and assessed short-term PPT/TS changes after lumbar spinal manipulation or sham, finding no ba…

Effectiveness of Physical Therapy Combined With Epidural Steroid Injection for Individuals With Lumbar Spinal Stenosis: A Randomized Parallel-Group Trial
A multicenter randomized trial in older adults with lumbar spinal stenosis found that epidural steroid injections (ESI) with back education alone and ESI plus multimodal physical therapy (PT) both improved disability, with no clear advantage of adding PT to ESI for ODI outcomes,…

Outcomes of ECAP-controlled closed-loop spinal cord stimulation therapy in JAPAN: how to increase patient satisfaction with spinal cord stimulation
In six Japanese patients with chronic refractory low back and leg pain, ECAP-controlled closed-loop spinal cord stimulation (Inceptiv) was associated with improved 2.1-meter walking time, lower NRS pain scores, reduced uncomfortable stimulation, and high satisfaction.
