Want to assess joint mobility effectively? This guide breaks it down into 5 simple steps to help you evaluate joint function and plan treatments safely:
- Safety Screening: Identify risks like fractures, infections, or joint instability before proceeding.
- Patient History & Pain Analysis: Use tools like the SIN scale (Severity, Irritability, Nature) to understand pain patterns and limitations.
- Range of Motion Testing: Measure joint movement with tools like a goniometer and document end-feel types (e.g., soft tissue, bone-to-bone).
- Joint Movement Quality: Grade stiffness or hypermobility using scales like Kaltenborn-Evjenth (0-6).
- Treatment Plan: Tailor interventions using methods like Maitland or Kaltenborn based on findings.
Each step builds on the last to ensure safe, personalized care. By following this structured approach, you’ll identify mobility issues effectively and create a targeted treatment plan.
Maitland Mobilization Grades
Step 1: Safety Screening
Start your safety checks by identifying potential risks to avoid issues like temporary discomfort, which occurs in about 23% of manual therapy cases [8]. These evaluations play a critical role in shaping the treatment plan later on (Step 5).
Safety Checklist
Here are the key factors to consider:
| Absolute Contraindications | Special Precautions Required |
|---|---|
| Recent fractures | Osteoporosis |
| Active infections | Hypermobility syndromes |
| Malignancy | Recent surgeries |
| Acute rheumatoid arthritis | Blood-thinning medications |
| Unstable fractures | Pregnancy |
For patients with osteoporosis, it’s essential to review recent bone density scans and calculate fracture risk using tools like the FRAX® algorithm [1][3].
Warning Signs
Be on the lookout for critical red flags, such as:
- Severe, persistent pain that doesn’t match the clinical picture
- Neurological symptoms like numbness, tingling, or weakness
- Signs of vascular issues, including limb discoloration
- Unexplained swelling or inflammation
- Fever or other signs of infection [1][5]
To further assess nerve involvement, use tests like dermatome evaluations and nerve tension tests (e.g., Straight Leg Raise) [2][6]. These assessments tie into the pain analysis covered in Step 2 for a more thorough risk review.
Make sure to document all findings using a standardized 0-3 scale to measure instability [2][3].
Step 2: Patient History and Pain Assessment
Once the safety screening is complete, the next step is digging into the patient’s pain history and experience. This process combines structured pain measurement with specific questions about the joint condition to guide treatment planning.
Pain Rating with SIN Scale
The SIN scale (Severity, Irritability, Nature) is a useful tool for understanding pain patterns. It helps clinicians decide how intense the treatment should be and how to adjust it over time.
| Component | Assessment Method | Clinical Use |
|---|---|---|
| Severity | 0-10 numeric scale | Helps set initial treatment level |
| Irritability | Onset speed and duration | Determines session frequency |
| Nature | Pain quality description | Guides technique selection |
When evaluating irritability, focus on these factors[1][3]:
- How quickly pain starts during activities
- How long symptoms last after being triggered
- Time needed for recovery
- Effect on daily activities
- Symptom patterns throughout the day
Questions About Joint Problems
Ask specific questions to understand the injury’s background and its effect on daily life. This helps paint a clear picture of the condition and its impact[3][4].
Key Questions to Ask:
- When and how did the injury occur?
- What activities worsen the symptoms?
- What treatments have been tried, and did they help?
- What daily tasks are limited by the pain?
Make sure to document pain levels alongside functional abilities. For instance: "Patient reports 3/10 pain at rest, rising to 7/10 with full knee extension. Can stand for 15 minutes before pain increases"[1][2][4].
This detailed pain profile is crucial for planning movement tests in Step 3.
Tools like LEFS or Quick DASH can help track pain patterns and measure progress over time[1][2][4]. These tools are useful for adjusting treatment as needed.
Step 3: Testing Joint Movement Range
Once you’ve gathered the patient’s pain history, the next step is to evaluate their joint movement range. This involves both passive and active movement assessments.
End-Feel Types
Assessing the "end-feel" of a joint helps differentiate between normal joint function and potential issues. The sensation felt at the limit of passive movement provides key insights into joint health [1][3].
| End-Feel Type | Description | Clinical Example | What It Indicates |
|---|---|---|---|
| Soft Tissue | Soft, cushioned stop | Elbow flexion | Normal finding |
| Tissue Stretch | Gradual tension increase | Hamstring stretch | Expected resistance |
| Bone-to-Bone | Hard, abrupt stop | Elbow extension | Normal limitation |
| Empty | Movement stops from pain | Shoulder impingement | Needs further investigation |
| Springy Block | Elastic resistance | Meniscus tear | Suggests joint pathology |
If the end-feel deviates from what’s expected, it can help pinpoint specific areas requiring treatment [3].
Pain Pattern Records
During movement testing, systematically document pain patterns to get a clearer picture of the problem. Here’s what to track:
- Movement Arc: Use a goniometer to record the exact degrees where pain starts and stops.
- Pain Intensity: Note any fluctuations in pain level using a numerical scale.
- Movement Quality: Observe for irregularities like clicking, grinding, or uneven motion.
To ensure accuracy, always use standardized positions and properly place the goniometer. Comparing the affected side with the unaffected side helps establish baseline differences. For instance, normal knee flexion typically falls between 135-150 degrees [3].
The resistance felt during passive range of motion (ROM) testing is another important diagnostic clue. Record both numerical measurements (like goniometer readings) and qualitative observations (such as crepitus or compensatory movements) [3]. These findings will directly inform Step 4, where joint stiffness and movement quality are evaluated.

Step 4: Joint Movement Quality Tests
Building on the range of motion measurements from Step 3, these tests focus on identifying specific mobility challenges by assessing the quality of joint movement.
Movement Test Methods
To evaluate joint movement quality, standardized techniques are used to assess accessory movements between joint surfaces.
- Test end-range play, directional glides, and joint distraction by applying controlled force.
- Ensure accurate results by stabilizing the proximal segment while applying force to the distal segment [1][3].
Joint Stiffness Grades
The Kaltenborn-Evjenth 0-6 scale is a tool used to measure joint mobility and guide treatment [3].
"Normal joint play is considered grade 3, while grades 1-2 indicate hypomobility and grades 4-5 indicate hypermobility [3]."
Here are some signs to watch for:
Hypomobility Signs:
- Resistance increases during movement
- Limited accessory motion
Hypermobility Signs:
- Soft or empty end-feel
- Excessive joint play
- Poor movement control
It’s important to note that stiffness readings can vary depending on the time of day [1][3]. Consistent force during testing ensures reliable grading. These grades provide clear benchmarks for creating focused mobilization plans.
Step 5: Treatment Plan Development
Using the stiffness grades identified in Step 4, choose mobilization techniques tailored to the specific limitations found during the assessment. A well-thought-out treatment plan combines these findings with the most suitable mobilization methods.
Kaltenborn vs Maitland Methods
These two popular systems take different paths for joint mobilization and treatment. Knowing their differences helps therapists pick the best approach for each patient.
| Aspect | Kaltenborn System | Maitland System |
|---|---|---|
| Primary Focus | Joint play and mechanics | Pain response and tissue resistance |
| Assessment Method | End-feel and joint play testing | Pain provocation and movement analysis |
| Treatment Style | Prolonged positional stretches | Rhythmic back-and-forth movements |
Which system to use depends on the patient’s condition and treatment goals. For instance, research shows that Maitland Grade III mobilizations increased knee flexion by an average of 13.4 degrees, compared to just 6.2 degrees with Grade I techniques [7].
Choosing Treatment Grades
Selecting the right mobilization grade involves evaluating pain levels and joint mobility. Here’s how to align grades with patient needs:
For acute conditions:
- Use Grades I-II
- Perform small, pain-free movements
- Opt for shorter, more frequent sessions (15-20 minutes)
For chronic or stiff joints:
- Apply Grades III-IV, which involve larger movements
- Focus on improving mobility
- Work at the joint’s end range when appropriate, addressing abnormalities noted during Step 3 testing
- Plan longer sessions (30-45 minutes)
Acute cases typically require 3-5 sessions per week, while chronic conditions may need only 1-2 sessions, depending on irritability levels recorded in Step 2 [1][3].
Track progress and make adjustments by monitoring:
- Pain levels using standardized scales
- Changes in joint mobility
- Functional improvements
- Pain patterns documented during Step 2
As symptoms improve, shift from pain-relief techniques (Maitland) to more joint-specific methods (Kaltenborn) [1][3].
Conclusion: Assessment Steps Review
Assessing joint mobilization requires a structured clinical approach that prioritizes safety and informed decision-making. A five-step process helps ensure treatment plans are tailored to individual needs while staying grounded in proven methods.
The process begins with safety screening, where potential risks like recent fractures, active infections, or malignancies are identified to rule out unsafe mobilization [1][6]. Next, the patient history and pain assessment phase uses the SIN scale (Severity, Irritability, Nature) to evaluate pain characteristics accurately [2].
Range of motion testing provides essential data by assessing end-feel, while joint movement quality testing evaluates stiffness through specific grading.
Each step builds on the previous one to create a cohesive plan. Safety limits identified in the first step guide the intensity of treatment, pain profiles from the second step shape treatment choices, and mobility data from steps three and four inform the techniques used. This integrated approach ensures that every part of the assessment contributes to a well-rounded and individualized treatment strategy [1][3].
