Study Notes

0- to 180-Degree Notation System

Used for measuring range of motion (ROM) of upper and lower extremity joints
Anatomical position is 0 degrees for flexion-extension and abduction-adduction
Neutral position is 0 degrees for rotation
ROM starts at 0 degrees and proceeds towards 180 degrees
Also referred to as the neutral zero method
Widely used globally

Hyperextension

Defined as greater than normal extension ROM beyond the starting position of 0 degrees

Active ROM

Arc of motion produced by individual's voluntary unassisted muscle contraction

Capsular Patterns of Restricted Motion

Pathological conditions involving the entire joint capsule cause a specific pattern of restriction in passive motions
Restriction involves a fixed proportion of one motion relative to another
Example: Elbow joint - greater limitation of flexion than extension

Beighton Hypermobility Score

Valid instrument to measure generalized joint mobility in children aged 8 to 12 years
Assesses ability to:
- Passively oppose thumb to forearm
- Passively extend fifth MCP joint beyond 90 degrees
- Hyperextend elbow more than 10 degrees
- Hyperextend knee more than 10 degrees
- Place palms on floor by flexing trunk with knees straight
Each item contributes 1 point for each side/action
Total score ranges from 0 to 9

Factors Affecting ROM

Age: Significant differences exist between age groups for both upper and lower extremities, as well as spine
Gender: Women typically have greater knee and upper extremity ROM than men
Other factors: BMI, occupation, recreational activities, testing position, instrument used, examiner experience, and time of day

Muscle Length Testing

Maximal muscle length is the greatest extensibility of a muscle-tendon unit
Assessed indirectly by determining the maximal passive ROM of the joint(s) crossed by the muscle
Purpose: To determine if hypomobility or hypermobility is caused by the length of the inactive antagonist muscle or other structures
Muscles are categorized by the number of joints they cross:
- One-joint muscles
- Two-joint muscles
- Multi-joint muscles
One-joint muscle length testing is assessed by measuring passive ROM in the opposite direction of the muscle's action
Two-joint muscle length testing:
- The muscle is lengthened over both its proximal and distal joints
- One joint is held in full ROM while the examiner attempts to further lengthen the muscle by moving the second joint through full ROM
- Length is indirectly assessed by measuring passive ROM at the second joint
Multi-joint muscle length testing:
- Similar to two-joint muscle testing
- The muscle is lengthened over all joints except for one last joint
- Passive ROM is measured at the last joint to be moved

Ehlers-Danlos Syndrome

Ehlers-Danlos syndrome (EDS) affects all major body systems in addition to joint hypermobility and musculoskeletal pain.

Hypermobility Syndrome

Hypermobility syndrome (HMS) or benign joint hypermobility syndrome (BJHS) describes healthy individuals with generalized hypermobility and musculoskeletal symptoms.
Joint laxity in individuals with HMS is thought to be caused by inherited collagen abnormalities and regular physical exercise.

Diagnosing Hypermobility Syndrome

Traditionally, HMS diagnosis involves excluding other conditions, a Beighton score of at least 4, and arthralgia in 4+ joints for over 3 months.
Beighton score criteria may be inadequate for children because 65% of children aged 4-7 years scored above 4 on the Beighton scale.
Higher Beighton score cutoffs (7 for 3-9 year olds, 4 for 10-16 year olds) may be needed for children.
There is a need for international agreement on firm cutoff points and standardized measurement for the Beighton mobility tasks.

Additional Criteria for Diagnosing Hypermobility Syndrome

Additional criteria for HMS diagnosis include specific joint motions and extra-articular signs.
Specific joint motions to consider:
- Shoulder lateral rotation > 90 degrees
- Cervical spine lateral flexion > 60 degrees
- Distal interphalangeal joint hyperextension > 60 degrees
- First metatarsophalangeal joint extension > 90 degrees
Individuals with HMS have significantly poor joint position sense compared to people without HMS.

Beighton Score as a Measure of Hypermobility

Beighton score is a valid measure of generalized joint mobility in children aged 8-12 years when goniometry is used.
Additional items suggested by Grahame for the Beighton score are not needed.

Factors Affecting Range of Motion

Factors affecting range of motion (ROM) include: age, gender, active vs. passive motion, body mass index, occupational activities, recreational activities, testing position, type of instrument, examiner experience, and time of day.

Age Effects on Range of Motion

Older adults generally have less ROM in the extremities compared to younger adults.
Age-related ROM changes are joint and motion specific and may affect males and females differently.
Wrist flexion-extension, hip rotation, and shoulder rotation ROM decrease with increasing age, while thumb MCP joint flexion ROM remains consistent.
There is a small (3-5 degree) decrease in mean active hip and knee motions between the youngest (25-39 years) and oldest (60-74 years) age groups.
Spinal ROM decreases with age, specifically in neck extension and flexion, lateral flexion, and rotation.
Cervical ROM decreases by approximately 4 degrees per decade.
Thoracolumbar spinal mobility decreases with age, with an average decrease of 8 degrees per decade in flexion-extension.
Lumbar flexion and extension decrease with increasing age, primarily between 40-50 years and after 60 years of age.

Gender Effects on Range of Motion

Gender differences in ROM are joint and motion specific.
Females often have slightly greater ROM than males, especially in adults.
Greater flexibility in females for 14 out of 17 tested joint motions.
Females generally have greater ROM than males in the knee, upper extremity, and cervical spine motions.
Gender has no significant influence on 3-dimensional cervical ROM, except in the 70-79 year old group.

Muscle Length Testing

Muscle length refers to the maximal extensibility of a muscle-tendon unit, the maximal distance between the muscle's proximal and distal attachments.
Muscle length is assessed indirectly by measuring the maximal passive ROM of the joint(s) crossed by the muscle.
Muscle length testing determines whether hypomobility or hypermobility is caused by the length of the inactive antagonist muscle or other structures.
Muscle length affects passive joint ROM, along with joint surfaces, capsule, ligaments, fascia, and skin.
Muscles are categorized by the number of joints they cross:
- One-joint muscles: cross one joint
- Two-joint muscles: cross two joints
- Multi-joint muscles: cross multiple joints
One-joint muscles usually have enough length to allow full passive ROM.
Shortened one-joint muscles decrease passive ROM in the direction opposite to the muscle's action and result in a firm end-feel.
