Tendon inflammation in the thumb side of the wrist.
Do you experience sharp pain on the thumb side of your wrist, especially when gripping, pinching, or turning your wrist? Does lifting a coffee cup, opening a jar, or picking up your baby cause shooting pain along your thumb? These symptoms might indicate De Quervain's tenosynovitis—a common and often debilitating condition affecting the tendons that control thumb movement.
At Vaughan Physiotherapy Clinic, our experienced therapists specialize in the conservative management of De Quervain's disease, helping patients from Thornhill, Vaughan, and North York achieve significant pain relief and functional recovery without the need for injections or surgery. Our evidence-based, multi-modal approach addresses the underlying degenerative changes in the tendons while restoring pain-free movement and strength for work, childcare, and daily activities.
Let's explore what De Quervain's tenosynovitis is, how to recognize it, and most importantly, how our proven physiotherapy techniques can help you return to confident, pain-free use of your hand.
De Quervain's disease, also referred to as De Quervain's tenosynovitis or tendinopathy, is a common pathology affecting the wrist and hand, first described in 1895. It is characterized by pain and tenderness over the first dorsal compartment of the hand—the area on the thumb side of your wrist.
De Quervain's is described as a painful stenosing tenosynovitis of the first dorsal compartment. The primary pathological issue is typically a degenerative thickening of the extensor retinaculum covering the first extensor compartment.
The affected structures:
The condition results in pain caused by the resisted gliding of two specific tendons within a narrow fibro-osseous canal:
The mechanism of pain:
This painful condition is usually caused by overuse or an increase in repetitive activity, leading to shear microtrauma as these tendons repetitively glide beneath the compartment sheath over the radial styloid (the bony prominence on the thumb side of your wrist).
Here's an important distinction: Although initially thought to be inflammatory (hence "tenosynovitis"), studies on the histology of the disease suggest it is primarily a non-inflammatory thickening of the extensor retinaculum. This means the underlying pathological process appears to be degenerative rather than inflammatory.
Why this matters: Understanding that De Quervain's is degenerative rather than inflammatory changes how we treat it—degenerative tendon conditions respond best to specific types of exercises and manual therapy rather than simply rest and anti-inflammatories.
De Quervain's is a common condition affecting specific populations:
General population:
Working-age adults:
Incidence rates (young, active population):
Why women are more affected:
De Quervain's is especially prevalent among pregnant and lactating women. The repetitive motions of lifting and holding a baby, combined with hormonal changes affecting tendon tissue, make new mothers particularly vulnerable.
De Quervain's is particularly prevalent among people who perform repetitive tasks involving hand twisting or bending. Predisposing movements include:
Occupational risks:
Recreational activities:
Life circumstances:
Understanding the characteristic presentation of De Quervain's helps distinguish it from other wrist and thumb conditions.
Pain and tenderness:
Patients typically complain of radial wrist pain with thumb movements. There is generally pain and tenderness over the first dorsal compartment of the hand, with tenderness often found directly over the radial styloid process (the bony bump on the thumb side of your wrist).
You may notice a tender nodule over the radial styloid—a palpable thickening of the tissues in this area.
Impaired function:
Patients display impaired function of the wrist and hand, with specific difficulties including:
Examination often reveals:
Pain is typically aggravated by predisposing movements such as:
The initial diagnosis of De Quervain's disease is usually made based on clinical symptoms combined with physical examination.
The test most often used for De Quervain's disease is the Finkelstein test:
How it's performed:
The original description involves grasping the patient's thumb and quickly moving the hand toward the ulnar side (pinky side), which elicits excruciating pain over the styloid tip in affected individuals.
However, the original Finkelstein test is considered "somewhat crude" and may elicit pain even in healthy subjects. Therefore, modern practitioners often use less crudely performed variants, sometimes comparing the symptomatic hand to the healthy hand.
A staged approach includes:
What a positive test means: A positive Finkelstein test causes reproduction of pain at the radial styloid, strongly suggesting De Quervain's disease.
A screening tool for De Quervain's disease consists of seven items:
The result is considered positive when five or more items are present.
When symptoms are present, healthcare professionals should consider other conditions that may present similarly:
Distinguishing between these conditions is important because treatment approaches differ.
De Quervain's disease can significantly impact your quality of life, affecting your ability to work, care for family members, and perform daily activities that require hand use. Without appropriate treatment, the condition can become chronic and increasingly debilitating.
Functional limitations:
Progressive nature:
With appropriate intervention, the prognosis for De Quervain's disease is generally favorable:

Recover faster, move better, and feel stronger with expert physiotherapy. Our team is here to guide you every step of the way.
Physiotherapy intervention can significantly help in the management of De Quervain's tenosynovitis by reducing pain, improving functional ability, and addressing the underlying degenerative pathology. At Vaughan Physiotherapy Clinic, we use a multi-modal approach incorporating various evidence-based techniques.
Research demonstrates that physiotherapy produces measurable improvements:
Pain reduction: In a case series, multi-modal physiotherapy resulted in median pain scores decreasing from 5 to 2.8 on the 11-point Numeric Pain Rating Scale after treatment.
Functional improvement: The same case series showed functional disability scores (DASH questionnaire) reduced from 48% to 19% after treatment.
Complete resolution: Case reports document complete resolution of De Quervain's complaints using conservative management, with patients remaining pain-free at long-term follow-up.
Success comparable to injections: The 75% success rate achieved with physiotherapy is comparable to the success rate reported for corticosteroid injections (83% cure rate), but without the risks associated with injections.
Our multi-modal approach addresses De Quervain's through several mechanisms:
1. Stimulating Tendon Remodeling
Because De Quervain's is primarily a degenerative (non-inflammatory) condition, eccentric muscle training stimulates remodeling in degenerated tendons. This is fundamentally different from simply resting the area—controlled loading actually promotes healing of degenerative tissue.
2. Restoring Pain-Free Movement
Mobilization with Movement (MWM) techniques correct joint positional faults and restore pain-free movement. MWM can result in immediate pain relief during and after application, which facilitates the use of greater force during beneficial eccentric exercises.
3. Addressing Soft Tissue Restrictions
Manual therapy and soft tissue techniques help manage symptoms through myofascial release, soft tissue manipulation, and specialized techniques like tool-assisted fascial stripping.
4. Reducing Mechanical Irritation
Splinting decreases the mechanical friction of the APL and EPB tendons by immobilizing the wrist and thumb, keeping them straight and allowing healing to occur.
5. Patient Education
Activity modification instructions are essential—patients must learn to avoid activities that cause mechanical friction of the affected tendons while maintaining overall hand function.
Our comprehensive treatment plan integrates patient education, manual techniques, therapeutic exercises, and supportive modalities for optimal outcomes.
Comprehensive Evaluation:
Our therapists conduct a thorough assessment including:
Essential Patient Education:
According to expert consensus, patients should always receive instructions, and these instructions must be combined with another form of treatment—they should never be used alone.
We provide instructions on three levels:
Level 1 - Activity Instructions:
Level 2 - Function Instructions:
Level 3 - Pain Instructions:
Splinting Recommendation:
We typically recommend a long lower-arm based splint incorporating the wrist to decrease mechanical friction of the APL and EPB tendons. The splint immobilizes the wrist and thumb, keeping them straight.
Splinting protocol:
Our structured intervention typically involves regular sessions (often 2-3 times weekly initially), with each session lasting 30-45 minutes. Patients are typically treated for a median of 8 sessions.
Mobilization with Movement (MWM) Techniques:
MWM is a cornerstone of our approach, often involving a medial glide of the carpus (wrist bones):
How it works:
Why it's effective: By reducing pain during movement, MWM allows us to progress exercises more quickly and effectively than would otherwise be possible.
Eccentric Muscle Training:
This is a critical component addressing the degenerative nature of De Quervain's:
Eccentric hammer curl protocol:
The key principle: Eccentric exercises (where the muscle lengthens under tension) stimulate remodeling in degenerated tendons. Research shows that increasing the frequency of eccentric exercises and home care leads to improvement.
Soft Tissue and Manual Therapy:
We use various hands-on techniques to address tissue restrictions:
Adjunctive Modalities:
Depending on your presentation, we may incorporate:
Ultrasound therapy:
High-Voltage Electrical Stimulation (HVES):
Kinesiology taping:
Advancing exercises:
Gradual activity reintroduction:
Weaning from splint:
Home program continuation:
Activity modification:
Monitoring:
Based on the European HANDGUIDE consensus, treatment selection is determined by the severity and duration of your condition, arranged in a therapeutic hierarchy from lightest to most severe:
For mild to moderate cases:
Instructions + NSAIDs (IN):
Instructions + Splinting (IS):
Instructions + NSAIDs + Splinting (INS):
Instructions + Physiotherapy:
Instructions + Corticosteroid Injection (IC):
Instructions + Corticosteroid Injection + Splinting (ICS):
Instructions + Surgery (IO):
Important note: Healthcare professionals maintain flexibility to skip treatment steps if they anticipate a treatment will be ineffective or cause complications—not all steps must be performed for every patient.
Typical physiotherapy course:
Splinting duration:
Short-term outcomes (4-8 weeks):
Pain reduction:

Conservative treatment (physiotherapy):
Long-term outcomes:
Positive prognostic factors:
Negative prognostic factors:
Once you've achieved relief, preventing recurrence requires ongoing attention to the activities and ergonomics that contribute to tendon stress.
For new mothers:
At work:
During activities:
Permanently modify high-risk activities:
The exercises you learn aren't just for recovery—they're for life:
Recognize signs of potential recurrence:
When you notice these signs:
Possibly, but it's risky to wait and see.
While symptom resolution could potentially occur due to the natural history of the condition, De Quervain's disease is described as a challenging condition to treat with conservative methods when symptoms become established.
The risks of waiting:
Our recommendation: Even if symptoms are mild, seek assessment and begin conservative management early. Early intervention with physiotherapy, education, and splinting produces the best outcomes and helps you avoid more invasive treatments like injections or surgery.
This is an important distinction because treatments differ:
De Quervain's Tenosynovitis:
CMC-1 Osteoarthritis (Thumb Arthritis):
Why it matters: Your therapist will carefully differentiate between these conditions during assessment, as both can occur in similar populations but require different treatment approaches.
Many patients achieve excellent results with physiotherapy alone and never need an injection.
Consider physiotherapy first because:
Injections may be appropriate if:
Important note: Even if you receive an injection, physiotherapy is still recommended to address underlying biomechanical issues and prevent recurrence.
Yes, with modifications—in fact, modified activity is preferable to complete rest.
Work modifications:
For new mothers:
Activities to avoid or modify:
Your therapist will provide specific guidance for modifying your particular work activities.
Typical splinting duration is 3 to 8 weeks, but this varies based on your response:
Intensive splinting phase (first 3-4 weeks):
Weaning phase (weeks 4-8):
Maintenance phase (as needed):
Important: Don't discontinue splinting too early—premature splint removal is a common cause of symptom recurrence. Your therapist will guide you through the weaning process based on your specific progress.
With proper management, most patients maintain their improvements long-term.
Factors supporting sustained relief:
Risk factors for recurrence:
At 6-month follow-up: Studies show patients report minimal pain and disability with no recurrence when they maintain their management strategies.
If symptoms begin to return:
While we're confident in our treatment approaches based on available research and clinical experience, transparency about evidence quality is important:
Evidence status: The existing evidence base for physiotherapy in De Quervain's remains limited, with most data coming from case studies and case series rather than large randomized controlled trials.
What this means: While individual case outcomes are excellent and demonstrate significant improvements, more high-quality randomized controlled trials are needed to definitively establish optimal physiotherapy protocols.
Clinical reality: Despite limited high-level evidence, the clinical outcomes we achieve with patients are consistently positive, and the multi-modal approach we use is based on sound biomechanical principles and the best available evidence.
Systematic review findings: Most recent reviews have found no strong evidence for or against conservative treatments for De Quervain's—this reflects the limited quality of available research rather than ineffectiveness of treatments.
The European HANDGUIDE consensus, established by hand surgeons, hand therapists, and PM&R physicians, provides important guidance:
