Stretch weakness Archives - Damien Howell PT

Muscle “stretch weakness” – How does the length of a muscle affect its ability to generate force/tension?

As a muscle contracts and shortens it can generate a greater amount of force/tension. However, as the length of the muscle becomes shortened or slack or lengthened or too long the muscle loses its ability to generate tension/force. The relationship between muscle length relative to a muscle’s ability to generate tension/force follows the Goldilocks principle.…

Potential Prevention Strategy for Exercise Associated Muscle Cramps

Exercise associated muscle cramp (EAMC) is a painful, spasmodic, and involuntary contraction of muscle that occurs during or immediately after exercise. The exact mechanism or cause of EAMC still remains unclear. There is a consensus the first aid treatment of EAMC is to stretch the affected muscle. However, Coppin and colleagues conclude that regular stretching…

That’s a Stretch: Why Stretching May Not Always be the Solution

It’s good to stretch a dollar. It’s bad to stretch the truth. But what about stretching your calves? That might depend on whether you believe Dr. Google every time a search result says to stretch sore calves. Calf stretching aims to increase the range of motion (ROM) for ankle dorsiflexion. “Dorsi” is a prefix meaning…

IT Band Syndrome – Controversy Regarding Stretching Exercise

The Iliotibial (IT) Band is a tendon on the lateral aspect of the hip/thigh/knee. It is a large, wide, thick tendon. A tendon is a structure that attaches muscle to bone. IT band syndrome is a typical injury occurring in runners. A commonly recommended treatment for IT band syndrome is stretching exercise. Searching Google for…

Knee Pain Wringing Out – Gait Deviation

Knee pain can develop because of a “wringing out”. I am not referring to banging a bell ring, but the counter-rotation motion that can occur at the knee joint. The knee joint consisting of the thigh and lower leg moves on three different planes of motion. The knee can flex and extend. The knee can…

Pain on Bottom of Heel: Too Much Big Toe Motion

Pain on the bottom of the heel (Plantar Heel Pain) is a complex problem with variable diagnoses and explanations. And with variable diagnoses there should be variations in treatment. Unfortunately, the common treatment recommendations do not recognize such variability. For example, the universal suggested treatment for plantar heel pain is calf stretching and stretching of…

Should you stretch it out – Pain too loose too stiff?

Generally, there are one of two scenarios related to musculoskeletal pain and injury. Either there is not enough movement or there is too much movement. If a muscle is in spasm, if a joint is stuck, or if a muscle-tendon unit has adaptively shortened in length are all examples of not having enough movement. If…

Hip Pain: Gluteal Tendon Problems Postures & Positions to Avoid

Tendon problems are a common diagnosis at Achilles, knee (patellar tendon), shoulder (rotator cuff), and elbow (tennis elbow) pain. Interestingly though, pain on the side of the hip is commonly thought to be an inflammation of bursa. Recent investigation has shown that pain on the side of the hip commonly thought to be trochanteric bursitis,…

Stiffness – Resistance to Change: Good or Bad?

In the realm of health and fitness, the term stiffness often has a bad connotation. In reality, being stiff can have positive benefits. When something is stiff, it is difficult to change. When the range of motion of a joint is limited, it is also described as stiff. There is an optimal range of motion…

Muscles and Stretching

What is known about benefits of stretching and flexibility exercises continues to evolve. Some commonly held beliefs are being supported with new research and some beliefs are being proven false. Common beliefs about stretching exercises are that stretching exercises decrease risk of injury, relieves pain associated with stiffness, and improves sports performance. Stretching exercises are…
