Neuro & muscle functional diagnostics

What does neuro & muscle functional diagnostics mean?

While imaging such as X-rays or MRI primarily shows structures, neuro & muscle functional diagnostics answers the question: How do nerves, muscles and the neuromuscular interaction work under resting and stress conditions? The procedures range from measurements of nerve conduction velocity to electromyography (EMG) to standardized strength, coordination and movement analyses.

• Nervous system: conduction, stimulus transmission and possible bottleneck syndromes
• Muscle function: activation, power development, fatigue and symmetries
• Movement: gait, posture, joint angles, load distribution and stability

The results make complaints measurable and comparable. In this way, the course of therapy can be monitored objectively and we can decide together with you which conservative steps make sense - such as physiotherapy, sensorimotor training, ergonomic adjustments or further clarifications.

When does diagnostics make sense?

• Radiating back pain, numbness or tingling (suspected nerve irritation)
• Loss of strength, muscle weakness or recurring muscle cramps
• Nerve entrapment syndromes (e.g. carpal tunnel, ulnar sulcus, peroneal nerve compression)
• Shoulder, knee or hip problems with suspected muscular imbalance
• After injuries or operations for follow-up and re-integration planning
• Unsteady gait, falls, feeling of instability, coordination deficits
• Performance stagnation in sports, recurring overload despite training
• Unclear pain despite normal imaging

Not every question requires all tests. Together we select the procedures that provide the highest informative value for your complaints and goals.

Our procedures at a glance

• Nerve function measurements: nerve conduction velocity (NLG), electromyography (EMG)
• Surface EMG and activation analyzes in the functional test
• Isokinetic and isometric strength measurements, hand strength, rate of force development
• Movement and gait analysis, pressure measuring plates, balance and Y-balance tests
• Functional ultrasound and elastography for muscle and tendon assessment
• Standardized scores (e.g. ODI, QuickDASH, LEFS) for progress documentation

The combination provides a holistic functional profile - from nerve conduction to everyday movement.

Nerve function measurements (EMG/NLG)

If nerve compression or irritation is suspected, EMG and NLG support the differentiation between root irritation (e.g. L5/S1) and peripheral constriction (e.g. carpal tunnel).

• Electroneurography (NLG): Measures the speed and strength of electrical signals in motor and sensory nerves.
• Needle EMG: Records the electrical activity of individual muscles to assess signs of denervation or reinnervation.
• Surface EMG: Non-invasive; shows activation patterns and timing in functional tests.

What does that say? Slowed conduction, conduction blocks or pathological spontaneous activity can indicate congestion, irritation or muscle disease. The findings are always compared with clinic and imaging.

Safety and tolerability: Surface measurements are very well tolerated. Needle EMG can cause short-term, local discomfort or small hematomas. Blood thinners, coagulation disorders and pacemakers are carefully considered in advance.

Muscle strength, coordination and fatigue

Strength is not just maximum value. For everyday life and sport, symmetry, control and resistance to fatigue are important. Standardized measurements make this visible.

• Isokinetic dynamometry: Objective force profiles of the knee, hip and shoulder at defined speeds.
• Isometric tests: Quickly and safely assess strength levels and side differences.
• Hand strength measurement: Simple marker for overall muscle status and rehabilitation progress.
• Rate of Force Development: How quickly strength is available - important for stability and sport.
• Y-balance, single-leg stance and jumping tests: coordination, stability, load tolerance.

Results are incorporated directly into training and therapy recommendations – for example, targeted strength or sensorimotor training, adjustment of stress parameters or return-to-sport recommendations.

Movement and gait analysis

The analysis of the movement sequence shows how joints, muscles and nerves work together. Anomalies are objectified and documented in a comprehensible manner.

• 2D/3D video analysis: joint angles, symmetries, quality of movement in everyday life and sports.
• Pressure measuring plates: load distribution, rolling behavior, stability and reaction strategies.
• Treadmill/gait analysis: step frequency, step length, ground contact times, asymmetries.
• Functional tests under fatigue: Reveals stress-dependent deficits.

The analysis results in concrete, everyday measures - from technical and ergonomic tips to exercises that specifically improve your pattern.

Functional ultrasound and elastography

Ultrasound shows muscles, tendons and nerves dynamically moving. Elastography complements the assessment of tissue stiffness. Together with EMG and strength tests, a precise picture emerges as to whether a structure is overloaded, irritated or functionally disturbed.

• Dynamic ultrasound: sliding of tendons, snapping phenomena, impingement during movement.
• Nerve ultrasound: caliber changes, sliding disorders in constriction syndromes.
• Elastography: Relative stiffness as an indication of irritation or healing process.

The results support conservative therapy planning and help to carefully weigh invasive measures.

Process in our practice (Hamburg-Winterhude)

Duration: depending on the question, approx. 30-90 minutes. Most tests are suitable for everyday use; special preparation is rarely necessary.

What follows from the results?

The diagnosis provides an objective basis for evidence-based, conservative therapy. The goal is to reduce pain, improve function and prevent relapses.

• Physio and training therapy: strength, coordination, sensorimotor control, economy of movement.
• Stress management: step-by-step plans, reconstruction, return to activity/sport.
• Ergonomics and everyday life: workplace, running and lifting techniques, footwear, aids.
• Targeted infiltrations under ultrasound (if indicated) for diagnosis or short-term relief.
• Accompanying diagnostics: Metabolism/inflammatory and micronutrient analysis if necessary.
• Interdisciplinary: Coordination with family doctor, physio, neurology if necessary.

We discuss transparently which measures are likely to be beneficial, which are optional and where there are limits. We do not make a promise of healing; We are working step by step on measurable progress.

Common findings – clearly explained

• Radiculopathy (e.g. L5/S1): Irritation of a nerve root; Appropriate exercises, relief and time are often crucial.
• Carpal Tunnel Syndrome: Slowed median nerve conduction; conservative options depending on the stage.
• Peroneal irritation: weakness in lifting the foot after overstretching or pressure; targeted training and relief.
• Myofascial imbalance: lack of activation/overload of individual muscle chains; Adjust training focus.
• Tendon overload: Unobtrusive structure but increased stiffness or activation pattern; Stress control helps.
• Postoperatively: Objective follow-up to see whether strength and coordination are returning as planned.

Risks, limitations and contraindications

Most procedures are low risk. Mild, short-term pain or small hematomas may occur during needle EMG. Absolute promises of healing cannot be derived from measured values; Findings must always be classified clinically.

• Relative contraindications: coagulation disorders, anticoagulation, local infections, lymphedema.
• Implants/pacemakers: Discuss with us in advance; certain tests are adapted or avoided.
• Pregnancy: Functional tests are usually possible; Invasive procedures only with strict indications.

Prepare and bring with you

• Bring previous findings and imaging (if available).
• Comfortable clothing/sports shoes for movement and functional tests.
• Skin care: No heavily greasy creams/lotions at planned measuring points on the day of the examination.
• Disclose medications/illnesses (especially blood thinners, pacemakers).
• Write down questions and goals – this way we make the best possible use of the time.

Quality, evidence and data protection

We work with standardized protocols, calibrated measurement systems and validated scores. Results are clearly documented so that the course and treatment effects remain comprehensible.

We treat your data confidentially in accordance with applicable data protection regulations. Findings will only be passed on to practitioners with your consent.
