License Image The sciatic nerve is the largest nerve in the body and arises from the L4 through S3 spinal nerves (and their roots). It exits the pelvis through the sciatic notch, and continues down the back of the thigh where it splits into the common fibular and tibial nerve at the knee. The common …
A dermatome is an area of skin that is mainly supplied by afferent nerve fibres from the dorsal root of any given spinal nerve.[1][2] There are 8 cervical nerves , 12 thoracic nerves, 5 lumbar nerves and 5 sacral nerves. Each of these nerves relays sensation from a particular region of skin to the brain.
Looking at the 31 pairs of spinal nerves including the cervical, brachial, lumbar, and sacral plexuses in detail.
Just as it sounds, spinal stenosis is a condition that affects the spine by narrowing the spinal column and compressing the spinal cord. To learn more about spinal stenosis, read this article on the symptoms, causes, diagnosis, and treatment.
All of us, at one time or another, has experienced back pain to some degree. It’s sometimes hard to explain the pain to someone else, because it only occurs during certain activities, or at s…
The meninges is a protective covering that surrounds the brain and spinal cord. Problems that impact this membrane can result in serious conditions.

License Image The tendons, ligaments and muscles surrounding a joint are what give it strength and stability. Ligaments and tendons are tough fibrous bands. Ligaments attach bone to bone, tendons attach muscle to bone. The anterior longitudinal ligament (ALL) and the posterior longitudinal ligament (PLL) run the entire length of the spinal column. The anterior …
Prehabilitation is defined as the process of augmenting functional capacity before surgery in preparation for the postoperative phase. This study intends to assess the feasibility of conducting a preoperative intervention program in patients with lumbar spinal stenosis and to report on the piloting of the proposed intervention. Patients were allocated to a 6-week supervised preoperative rehabilitation program or a control group. The intervention included supervised exercise sessions aimed to improve strength, muscular endurance, and spinal stabilization. Outcomes were measured at baseline, 6 weeks later and again 6 weeks, 3 months and 6 months after surgery. Sixty-five percent of admissible participants agreed to take part in the study, of which 5% dropped out before the end of the intervention period. Eighty-eight percent of potential training sessions were delivered without adverse event. Improvements were seen in favour of the experimental group at the preoperative assessment for active ranges of motion, leg pain intensity, lumbar extensor muscle endurance and walking capacities. Results show that slight modifications to the choice of outcome measures would increase feasibility of the main study. The absence of adverse events coupled with positive changes seen in dependant outcome measures warrant the conduct of a full-scale trial assessing the effectiveness of the intervention.
