Spinal Cord Stimulator (SCS) surgery manages chronic pain by implanting a device that delivers mild electrical pulses to the spinal cord. This electrical field disrupts pain signals before they reach the brain, offering relief for conditions like failed back surgery syndrome or complex regional pain syndrome. The recovery process is structured in phases, depending on whether a temporary trial or a permanent device is implanted.
Recovery Timeline for the Trial Procedure
The first phase is a temporary trial, which tests the device’s effectiveness before permanent implantation. This outpatient procedure involves inserting thin wires, called leads, into the epidural space near the spine, connecting them to an external stimulator worn on a belt. Recovery is typically short, lasting the duration of the trial, usually three to seven days.
During this period, patients must adhere to strict limitations to ensure the leads do not shift. Bending, twisting, or lifting objects heavier than a few pounds are prohibited. Patients must avoid showering or swimming to keep the temporary surgical sites and the external device dry. At the conclusion of the trial, the temporary leads are removed, and the insertion sites typically heal within a day or two.
The First Month After Permanent Device Implantation
If the trial successfully reduces pain, the next step is the permanent implantation of the leads and a pulse generator (battery), usually placed beneath the skin of the abdomen, flank, or upper buttock. The initial four weeks represent the acute healing phase, focusing on surgical site recovery. Patients will experience discomfort and swelling at the generator site and along the spine where the leads were placed.
Post-operative pain is managed with prescribed medication for the first week or two. Incision care requires keeping the wounds clean and dry to minimize infection risk. For the first month, stringent limitations are necessary to allow scar tissue to form around the leads, anchoring them in position. Patients must maintain a flat back posture and strictly avoid “BTL” movements: bending, twisting, and lifting anything over 5 to 10 pounds.
Resuming Daily Life and Physical Activities
The mid-term recovery phase begins after the first month and extends through the first three months, transitioning from physical healing to functional recovery. As the surgical incisions heal, the focus shifts to gradually reintroducing activities of daily life. Driving is typically permitted approximately two to four weeks post-operation, once the patient is off prescription pain medication and can comfortably perform an emergency stop.
Patients with sedentary jobs can often return to work within two to four weeks, while those with physically demanding roles may require six to eight weeks or longer. Light physical activity, particularly gentle walking, is encouraged early on to promote circulation and prevent stiffness. Physical therapy is often introduced around the six-week mark to help rebuild strength and flexibility in a controlled manner. Throughout this period, a specialist fine-tunes the device programming to optimize pain relief.
Full Recovery and Long-Term Limitations
Full recovery is achieved between three and six months after the permanent implant, when internal scar tissue has fully developed and stabilized the implanted leads. This stabilization reduces the risk of lead migration, allowing for the easing of most temporary physical restrictions. While high-impact sports like running or contact sports may be discouraged to protect the hardware, most patients can return to moderate-intensity activities, such as swimming, cycling, or golfing.
Patients must be aware of long-term considerations related to living with an implanted electronic device. The use of medical imaging technology, such as Magnetic Resonance Imaging (MRI), requires the device to be compatible, and the patient must inform medical providers about the implant. The pulse generator contains a battery that will eventually need replacement, involving a minor outpatient procedure typically performed after several years, depending on device type and usage.
