Why Assessment Skills Matter in Sports Massage
Before you place your hands on a client, you need to know what you are working with. A structured assessment tells you where the body is compensating, which tissues may be restricted, and whether massage is appropriate at all. In a sports context, athletes present with overuse patterns, acute injuries, and asymmetries that can be invisible without a systematic look. Your assessment findings also form the legal and professional record of your work. Employers, referring clinicians, and licensing boards expect massage therapists to document care accurately. The MBLEx tests your knowledge of assessment principles, and your state license holds you responsible for practicing within your scope — assessment is the gateway to that safe practice.
Postural Analysis: What You Are Looking For
Postural analysis is a visual screen performed before hands-on work. You observe the client standing relaxed in three views: anterior (front), lateral (side), and posterior (back). Use a plumb line or posture grid as a reference.
Anterior view: The plumb line should bisect the body. Note whether the head is centered, whether one shoulder is elevated, whether the hips are level, and whether the feet show equal turn-out.
Lateral view: The plumb line should pass through the ear, middle of the shoulder, mid-trunk, greater trochanter, just anterior to the knee, and just anterior to the lateral malleolus. Deviations — forward head, rounded shoulders, excessive lumbar lordosis or kyphosis — are noted here.
Posterior view: Check spinal alignment, scapular symmetry, and whether the gluteal folds and popliteal creases are level.
Record what you observe factually. Use directional and anatomical language: "Right shoulder elevated approximately 1 cm relative to left" rather than "shoulder looks off." Never diagnose a condition from a postural screen; describe what you see and let a qualified diagnostician interpret pathology.
Range-of-Motion (ROM) Testing
ROM testing tells you how freely a joint moves. There are two main types:
- Active ROM (AROM): The client moves the joint through its range under their own power. This screens muscle strength and willingness to move.
- Passive ROM (PROM): You move the joint while the client remains relaxed. This isolates joint and capsular structures.
A goniometer is the standard tool for measuring joint angles. It has a stationary arm, a moveable arm, and a fulcrum. Align the fulcrum over the joint's axis of rotation, the stationary arm with the fixed body segment, and the moveable arm with the moving segment. Read the angle at end range.
Key normal ROM benchmarks (approximate, for clinical reference):
- Shoulder flexion: ~180°; abduction: ~180°
- Hip flexion (knee bent): ~120–135°
- Knee flexion: ~135°
Always compare bilaterally. Note whether pain, crepitus, or muscle guarding occurs during movement. Stop immediately if the client reports sharp pain or you feel a bony block. ROM testing is a screen, not a treatment.
Safety Considerations for ROM Testing
- Never force a joint past its comfortable end range.
- Obtain informed consent before moving a client's limb.
- Ask about recent fractures, surgeries, or acute inflammation before testing — these may be contraindications.
- If a joint appears acutely swollen or hot, do not perform passive ROM; refer the client.
- Maintain proper body mechanics to protect yourself during passive movements.
SOAP Note Documentation
SOAP stands for Subjective, Objective, Assessment, Plan. It is the professional standard for session documentation across health-care settings.
S – Subjective: What the client tells you. Include chief complaint, pain location and quality (use a pain scale if appropriate), history, and anything affecting the session. Quote the client where helpful: "My right shoulder has ached for two weeks after pitching practice."
O – Objective: What you observe and measure. Postural findings, ROM measurements, tissue quality (hypertonic, tender, restricted), and techniques used during the session go here. Use precise anatomical language and include goniometer readings.
A – Assessment: Your professional summary of what the session revealed and how the client responded. This is not a medical diagnosis. Example: "Client presented with right-shoulder elevation and restricted AROM shoulder flexion at 140° bilaterally, with increased tissue tension noted in right upper trapezius and levator scapulae. Client reported decreased discomfort following soft-tissue work."
P – Plan: What happens next. Include recommended frequency, areas to address in future sessions, self-care instructions given to the client, and any referrals recommended.
Common SOAP Errors to Avoid
- Leaving any section blank — all four sections must be present.
- Placing objective measurements in the Subjective section, or client quotes in the Objective section.
- Using diagnostic language you are not licensed to use (e.g., "client has rotator cuff tear").
- Writing illegibly or using unexplained abbreviations.
- Failing to date and sign every note.
Complete, accurate SOAP notes protect you legally, support continuity of care, and demonstrate professional competence to employers and licensing boards.
Key terms8
Postural analysisA systematic visual examination of the client's standing alignment in anterior, lateral, and posterior views to identify asymmetries or deviations from neutral posture.
Active range of motion (AROM)The arc of joint movement produced by the client's own muscular effort, used to screen neuromuscular function and pain provocation.
Passive range of motion (PROM)The arc of joint movement produced by the therapist while the client remains relaxed, used to assess joint capsule and connective tissue mobility.
GoniometerA two-armed instrument with a protractor used to measure joint angles in degrees during range-of-motion testing.
SOAP noteA structured documentation format with four sections — Subjective, Objective, Assessment, and Plan — used to record client findings and session outcomes.
Plumb lineA vertical reference line used during postural analysis to compare the client's alignment against an ideal vertical axis.
End feelThe quality of resistance felt by the therapist at the limit of passive joint movement, which can indicate normal or pathological tissue response.
Bilateral comparisonThe practice of measuring or observing both sides of the body and comparing them to detect asymmetries in posture or movement.
Worked examples4
1. A client's shoulder flexion is measured with a goniometer. The stationary arm reads 0° and the moveable arm aligns to 155° at end range. The opposite shoulder measures 175°. What is the side-to-side difference, and how would you record this in a SOAP note?
- Step 1: Identify the two measurements — right shoulder flexion 155°, left shoulder flexion 175°.
- Step 2: Subtract to find the side-to-side difference: 175° − 155° = 20°.
- Step 3: Compare both values to the approximate normal benchmark of ~180° to note that both are mildly reduced, with the right more restricted.
- Step 4: In the Objective section of the SOAP note, record: 'AROM shoulder flexion: right 155°, left 175°; 20° side-to-side deficit on right.'
Answer: The side-to-side difference is 20°. SOAP Objective entry: 'AROM shoulder flexion: right 155°, left 175°; 20° deficit on right compared to left.'
2. During a postural analysis, you observe that one iliac crest appears approximately 2 cm higher on the right than on the left in the posterior view. How do you document this objectively without overstepping your scope of practice?
- Step 1: Record the observation using descriptive, anatomical language — describe what you see, not a diagnosis.
- Step 2: Quantify where possible: note the approximate elevation and the view in which it was observed.
- Step 3: Avoid diagnostic statements such as 'client has a leg-length discrepancy' or 'client has scoliosis.'
- Step 4: Write in the Objective section: 'Posterior view: right iliac crest elevated approximately 2 cm relative to left.'
Answer: Objective entry: 'Posterior view: right iliac crest elevated approximately 2 cm relative to left.' No diagnostic label is applied; observation is described factually.
3. A goniometer is placed for knee flexion. The therapist aligns the stationary arm along the femur and the moveable arm along the fibula. The client bends the knee and the goniometer reads 128°. The normal benchmark is approximately 135°. By what percentage is this client's knee flexion reduced from normal?
- Step 1: Identify the measured value (128°) and the benchmark (135°).
- Step 2: Find the deficit in degrees: 135° − 128° = 7°.
- Step 3: Calculate the percentage reduction: (7 ÷ 135) × 100 = 5.19%, which rounds to approximately 5%.
- Step 4: Record in the Objective section: 'PROM knee flexion: 128° (approximately 5% below normal benchmark of 135°).'
Answer: Knee flexion is reduced by 7° or approximately 5% from the normal benchmark. Objective entry: 'PROM knee flexion: 128°; approximately 5% below benchmark.'
4. You perform postural analysis and find: forward head posture in lateral view, elevated left shoulder in anterior view, and lumbar hyperlordosis in lateral view. Organize these findings into a correctly formatted Objective SOAP section.
- Step 1: Group findings by assessment view for clarity.
- Step 2: Use anatomical and directional language for each finding.
- Step 3: Do not interpret or diagnose — describe only what was observed.
- Step 4: Write the Objective section: 'Postural analysis — Anterior view: left shoulder elevated relative to right. Lateral view: forward head posture noted; increased lumbar lordosis observed. Posterior view: no additional deviations noted at this time.'
Answer: Objective section: 'Postural analysis — Anterior: left shoulder elevated relative to right. Lateral: forward head posture; increased lumbar lordosis. Posterior: no additional deviations noted.'
The math in this lesson1
Learners subtract goniometer readings (175 deg minus 155 deg) to record a 20-degree shoulder flexion deficit.
