Suspension Therapy
What is Suspension Therapy?
Suspension therapy offers a wide range of exercises that target strength, stability, flexibility, and balance. By adjusting the position of the straps and body angles, you can modify the intensity of the exercises to suit your fitness level.
Suspension therapy helps a person to improve their range of motion (ROM), improve muscle strength, and reinforce body domains by utilizing ropes and slings.
Suspension liberates the body from the conflict of fabric on which the body parts may be relaxing and it lets unrestricted motion without resistance. Late Mrs. Guthrie Smith originated the suspension device.
What are the Principles of Suspension Therapy?
It is working under the following principles:
- Friction
- Pendulum
- Eliminating gravity movement
Friction:
It happens when a certain texture moves on another texture. In suspension therapy, a therapist will utilize surfaces that are more soft and slippery so has more nominal friction generating smooth and easy motion.
Pendulum:
In the Pendulum weighty fabric is suspended by the lightweight thread if the danger is used to the pendulum resulting in free movement. One full swing is named oscillation.
While oscillating, the arc of motion of the pendulum assembles a component of the bottom of the cone. The oscillation will persist until the power comes down. The oscillation space comes low gradually with the resistance of the air and friction.
A muscle contraction is required to start the oscillation. Some mechanism is operated for suspension therapy to preserve the property of muscle, improve the range of movement (ROM), and strengthen the muscles.
Eliminating gravity movement:
If the individual has a muscle strength grade 2 is indicated for suspension training. If the muscle strength is lower than grade 2, It’s challenging to accomplish the suspension therapy training by the person himself. The individual should have minimal muscle contraction strength of grade 2 to accomplish suspension therapy activities.
If the muscle strength is above grade 3, the person can go for the against-gravity activity rather than suspension therapy.
What are the Parts of Suspension Therapy?
- Fixed point: suspension frame
- Pulley:
- Supporting ropes:
- Single rope
- Double rope
- Pulley rope
- Sling:
- Single sling
- Double sling
- Three-ring sling
- Head sling
- Wooden cleat:
- Dog clip, S hook:
Suspension frame:
- It is constructed of stainless steel/plastic-coated steel.
- The ceiling and head-end side show the 5cm metal mesh and the remaining sides are held open.
Pulley:
It provides a mechanical advantage. Pulleys are utilized to lessen the load of lifting the entire body/body regions. Sometimes single/double pulleys are operated relying on the condition. If the body portion is oversized. For example, in the trunk, thorax, and thigh, double pulleys are utilized.
Supporting rope:
There are three kinds of supporting ropes utilized for the suspension to avoid dropping.
- Single rope
- Pulley rope
- Double rope
Single rope
- It has a round settled at one end by which it is hinged up.
- The other end of the rope passes via one end of the wooden cleat via the circle of a dog clip and the further end of the cleat and then knotted.
Pulley rope
- This has a dog clip connected at one ending of the rope which then passes over the spin of a pulley.
- The rope then passes via the cleat & second dog clip.
Double rope
- Consists of two pulleys at the upper & more inferior attachments.
- So here there is a computerized benefit of 2.
Slings
There are four types of functional slings:
- Single sling
- Double sling
- Three-ring sling
- Head sling
Single sling
- Constructed of canvas wrapped with smooth webbing and with a D circle ring at both ends.
- Size: 68cm length & 17cm width.
- Operated for elbow and knee joint motion
- Occasionally tucked in the figure of eight methods to sustain the wrist and ankle.
Double sling
- Larger than a single sling
- It’ll have more than two sides with the D circle rings.
- Operated to reinforce larger portions for example the thorax, trunk, and thigh.
- Size: 68cm length & 29cm width.
Three-ring sling
- Size: 75cm length & 3-4cm width, including three-D circle rings.
- Two D circle rings at each ending of the sling and one in the center preserved forcing.
- Operated for wrist and ankle region motion.
Head sling
- This is a brief, divided sling with it is two halves sewed concurrently at an arc to construct a halfway slit.

What are the Types of Suspension Therapy?
- Axial suspension
- Vertical suspension
- Pendular suspension
Axial suspension
- The joint axis is assumed as the pinpoint of the suspension.
- The slings beyond the axis of the joint to support the extremity.
- If the activity is started the extremity is dragged on each side.
- The component moves parallel to the ground.
Uses of axial suspension:
- Relaxation
- Sustain muscular property
- To boost the blood circulation
- Improve the venous drainage
- Improve the lymphatic drainage
Vertical suspension
- The center of gravity (COG) of the body region/body is assumed as a point of suspension.
- Operated to deliver reinforcement to the body region of the patients.
Uses of vertical suspension:
- To sustain the body portion
- To decrease the pressure sore.
Pendular suspension
- The point of suspension should be moved out from the joint axis.
- Activity generally brings place against gravity.
- Muscles will be obtaining resistance during movement if the axis is moved to oppose that motion.
Uses of pendular suspension
- To strengthen the muscle.
- To raise the muscle power
- Improve endurance.
Advantages of Suspension Therapy
- It lessens the load on the physiotherapist.
- Comfortable lifting the extremity.
- Active motion can be accomplished effortlessly with the lowest friction.
- More comfortable to carry the position of the extremity with slings and pulleys in the needed position.
Disadvantage of Suspension Therapy
- Especially complex and not always the first option for beginners in resistance exercise.
- Needed a lot of materials for example slings, ropes, and pulleys.
Indications of Suspension Therapy
- Spinal cord injuries.
- Hemiplegia.
- Post-operative muscle weakness.
Contraindications of Suspension Therapy
- Head injury
- Fracture
- Spinal cord injury
- Circulatory disorder etc.

What is the principle of suspension therapy?
Suspension mainly works on the following 3 principles:
Friction
Gravity eliminating
Pendulum
Who invented suspension therapy?
Guthrie Smith developed the suspension device. Which is constructed of wood and is utilized for varying the rope. It consists of two/three gaps for the rope route.
What are the health benefits of suspension?
Provide relaxation
Enhances core strength.
Constructs functional strength, agility, and power.
Portable easy to set up.
