Here is a comprehensive exam-ready overview of Fundamental Positions in Exercise Therapy Theory:
Fundamental Positions in Exercise Therapy
Starting Position - Definition
"Posture follows movement like a shadow. Every movement begins in posture and ends in posture." - Sherrington
The starting position is the posture from which a movement is initiated. It may be active or passive in character. Equilibrium and stability must be maintained in this position.
Starting positions are of two types:
- Fundamental (Starting) Positions
- Derived Positions
The 5 Fundamental Starting Positions
| # | Position | Abbreviation |
|---|---|---|
| 1 | Standing | St |
| 2 | Kneeling | Kn |
| 3 | Sitting | Sitt |
| 4 | Lying | Ly |
| 5 | Hanging | Hg |
1. STANDING (St)
The most difficult fundamental position to maintain.
Joint Position:
- Heels together and on the same line; toes slightly apart
- Knees together and straight
- Hips extended and slightly laterally rotated
- Pelvis balanced on the femoral heads
- Spine stretched to maximum length
- Vertex thrust upward, eyes level, looking straight forward
- Shoulders down and back
- Arms hang loosely to sides, palms facing inward toward the body
Muscles Working:
- Plantar flexors/dorsiflexors of ankle: balance tibia on the ankle
- Flexors/extensors of knee: keep the knee straight
- Hip extensors and abductors: maintain erect posture
- Trunk extensors + abdominals: stabilize the spine
- Neck muscles: maintain head position
Effects:
- Maximum anti-gravity muscle work
- Best for weight-bearing and balance training
- Promotes proprioception
Uses:
- Gait training
- Balance exercises
- Strengthening lower limb muscles
- Patient feels joy and efficiency during standing exercises
Derived Positions from Standing:
- Walk standing (one foot in front)
- Step standing (one foot on a step)
- Toe standing
- Stride standing (feet apart)
- Lunge position
2. KNEELING (Kn)
Joint Position:
- Body supported on the knees (together or slightly apart)
- Lower leg rests on the floor, feet plantar flexed
- Hips extended
- Pelvis balanced on femoral heads
- Spine stretched to maximum length
- Vertex thrust upward, eyes level
- Shoulders down and back
- Arms hang loosely to the sides, palms inward
Muscles Working:
- Flexors and extensors of knees: balance the femur vertically on the knee
- Hip extensors
- Trunk and spinal muscles
Effects:
- Reduces base of support vs. standing
- Eliminates foot and ankle involvement
- Challenges balance and hip stability
Uses:
- Hip and knee disorders where standing is not possible
- Core stability training
- Strengthening hip extensors and abductors
- When foot/ankle must be protected
Derived Positions from Kneeling:
- Half kneeling (one knee on ground, one foot flat)
- Crook kneeling (sitting back on heels)
- Prone kneeling (on all fours / quadruped)
- Knee lean forward
3. SITTING (Sitt)
Joint Position:
- Weight borne on the ischial tuberosities and thighs
- Hips and knees at approximately 90 degrees
- Feet flat on floor
- Spine erect
- Shoulders down and back
- Eyes level
Muscles Working:
- Hip flexors: maintain flexion
- Trunk extensors and flexors: stabilize the spine
- Less anti-gravity work than standing
Effects:
- Good stability (wide base of support)
- Reduced demand on lower limb anti-gravity muscles
- Allows free movement of upper and lower limbs
Uses:
- Upper limb exercises
- Trunk exercises
- Patients who cannot stand
- Elderly and debilitated patients
Derived Positions from Sitting:
- Long sitting (legs extended, 90° hip flexion)
- Cross sitting / tailor sitting
- Side sitting
- Forward lean sitting
- Crook sitting (feet on floor, knees bent)
- Ride sitting (astride a stool)
4. LYING (Ly)
Three primary variants:
- Crook lying (supine, knees bent, feet flat) - most common
- Prone lying (face down)
- Side lying
Joint Position (Supine/Crook lying):
- Entire body supported by a surface
- Spine in neutral
- Arms at sides
Muscles Working:
- Minimal anti-gravity work
- Trunk muscles work isometrically to stabilize
Effects:
- Minimum muscle effort required
- Maximum relaxation
- Complete elimination of gravity effects (in horizontal)
- Good for passive movements, relaxation, acute conditions
Uses:
- Acute injuries and early post-operative phase
- Relaxation techniques
- Passive and assisted exercises
- Breathing exercises
- Spinal traction
- Patients with poor tolerance for upright posture
Derived Positions from Lying:
- Prone lying
- Side lying
- Crook lying
- Half lying (head and trunk elevated)
- Prone kneeling
5. HANGING (Hg)
Joint Position:
- Body suspended by the hands (or feet in inverted hanging)
- Shoulders fully elevated and flexed
- Arms overhead gripping a bar/rings
- Spine elongated under traction effect
- Lower limbs hang freely
Muscles Working:
- Shoulder girdle muscles (especially shoulder elevators and depressors)
- Grip strength muscles
- Trunk muscles (to prevent excessive swing)
Effects:
- Spinal elongation / decompression
- Shoulder girdle strengthening
- Traction effect on the spine and hips
- Develops grip strength and shoulder stability
Uses:
- Spinal conditions (scoliosis, disc problems)
- Shoulder girdle strengthening
- Gymnastic and remedial exercises
- Grip strength development
Derived Positions from Hanging:
- Reach grasp hanging (wider grip)
- Inverted hanging
- Arm swing hanging
Factors for Selecting a Starting Position
When choosing the appropriate position for a patient, consider:
- Patient's ability - Can they maintain the position?
- Need for stabilization - How much support is required?
- Use of gravity - Is gravity to be assisted, resisted, or eliminated?
- Pain levels - Does the position aggravate or relieve symptoms?
- Intended effects - What therapeutic goal is to be achieved?
- Base of support - Stability vs. challenge
- Muscle work required - Active vs. passive
Summary Comparison Table (Exam-Focused)
| Position | Base of Support | Anti-gravity Work | Stability | Main Use |
|---|---|---|---|---|
| Standing | Small (feet) | Maximum | Least | Gait, balance, lower limb |
| Kneeling | Medium (knees) | Moderate | Moderate | Hip/knee rehab, core |
| Sitting | Large (buttocks + thighs) | Moderate | Good | Upper limb, trunk, elderly |
| Lying | Maximum (whole body) | Minimum | Maximum | Acute, relaxation, passive Rx |
| Hanging | Minimal (hands) | Upper body max | Least | Spine decompression, shoulder |
Key Principles to Remember for Exam
- The 5 fundamentals can be remembered as: S-K-S-L-H (Standing, Kneeling, Sitting, Lying, Hanging)
- Derived positions are modifications of the fundamental five to improve stability, alter leverage, promote relaxation, or isolate muscle groups
- As you progress from Lying → Sitting → Kneeling → Standing: anti-gravity muscle work increases progressively
- Hanging is unique - it uses the body's own weight for traction and overhead muscle work
- Sherrington's principle: every movement starts and ends in posture
