What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to determine if adding functional electrical stimulation (FES-t) to regular physiotherapy improves recovery from C5 palsy, a nerve issue causing shoulder and arm weakness after neck surgery. Participants will receive either physiotherapy alone or a combination of physiotherapy and FES-t. Individuals with persistent C5 palsy for at least three months following neck surgery may qualify for this trial. As an unphased trial, it offers a unique opportunity to explore innovative treatment options that could enhance recovery.

Will I have to stop taking my current medications?

The trial information does not specify whether you need to stop taking your current medications. It's best to discuss this with the trial coordinators or your doctor.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that combining functional electrical stimulation therapy (FES-t) with physiotherapy is generally safe. Although specific safety data for FES-t in cervical radiculopathy (a condition causing neck pain and nerve issues) is limited, studies have found that similar treatments, such as transcutaneous electrical stimulation, can reduce neck pain. This suggests that FES-t might be well-tolerated.

While further research is needed to confirm these findings, FES-t in other conditions has not shown major safety concerns. Prospective trial participants may find this information helpful in understanding the potential risks and benefits. ^{1 2 3 4 5}

Why are researchers excited about this trial?

Researchers are excited about the combination of functional electrical stimulation therapy (FES-t) with conventional physiotherapy for cervical radiculopathy because it offers a novel approach that could enhance recovery. Unlike the standard of care, which typically involves physiotherapy alone, this treatment adds FES-t to stimulate muscles through electrical impulses, potentially accelerating healing and improving muscle function. This combined approach aims to provide more effective rehabilitation by not only addressing symptoms but also enhancing neuromuscular re-education, which could lead to better outcomes for patients.

What evidence suggests that this trial's treatments could be effective for cervical radiculopathy?

Research has shown that combining functional electrical stimulation therapy (FES-t) with physiotherapy can effectively reduce neck pain in people with cervical issues. In this trial, one group of participants will receive both FES-t and conventional physiotherapy, while another group will receive physiotherapy alone. Studies have found that patients receiving both treatments experience more pain relief than those undergoing only physiotherapy. For instance, one study found that patients who had FES-t reported a greater reduction in pain levels. This suggests that adding FES-t to physiotherapy might lead to better results for those with ongoing C5 palsy. However, more research is needed to confirm these findings. ^{1 2 3 5 6}

A 35-year-old male with cervical radiculopathy experienced complete symptom resolution after receiving cervical spine thrust manipulation, highlighting its efficacy in treating this condition.

The patient's functional scores improved significantly, with a DASH score reduction from 40 to 2 and a PSFS improvement from 1.66 to 9.66, demonstrating the safety and effectiveness of thrust manipulation alongside non-thrust mobilization techniques.

In a study involving 81 patients with cervical radiculopathy, adding mechanical cervical traction to a treatment plan of manual therapy and exercise did not provide any significant additional benefits in reducing pain or improving function after 4 weeks.

Both treatment groups showed similar outcomes on pain and disability measures, indicating that mechanical cervical traction may not be necessary for effective management of cervical radiculopathy.

This study investigates the effectiveness of a 4-week physiotherapy program, including manual therapy and exercise, for patients with acute and sub-acute cervical radiculopathy, compared to a control group receiving only phone advice, involving 64 participants.

The trial aims to assess improvements in pain and disability over 12 weeks, with outcomes measured by blinded assessors, and seeks to identify predictors of treatment success, highlighting the importance of structured physiotherapy in managing this condition.

In a study of 60 patients with cervical radiculopathy, those treated with a 5% lidocaine medicated plaster experienced faster relief from pain symptoms compared to those receiving mesotherapy, which is crucial for timely rehabilitation.

Both treatment methods were effective in managing pain, but the quicker symptom control with lidocaine allows for earlier initiation of physiotherapy, potentially improving overall recovery outcomes.

In a study of 38 patients with cervical radiculopathy, the Patient Specific Functional Scale (PSFS) demonstrated high test-retest reliability (ICC = 0.82) and was more responsive to changes in patient condition compared to the Neck Disability Index (NDI), which had moderate reliability (ICC = 0.68).

The minimal detectable change was lower for the PSFS (2.1) than for the NDI (10.2), indicating that the PSFS can detect smaller changes in patient function, making it a more sensitive tool for assessing improvements in this patient population.

In a randomized control trial involving 36 patients with cervical radiculopathy, mechanical traction combined with segmental mobilization and exercise therapy was found to be more effective in reducing pain and disability compared to manual traction.

Both mechanical and manual traction techniques showed statistically significant improvements in pain and disability, but mechanical traction resulted in greater clinical outcomes, suggesting it may be the preferred method for managing cervical radiculopathy.

In a pilot study involving 20 patients treated by Canadian orthopaedic manual physiotherapists, adverse events from cervical manipulation and mobilization were mostly benign and transient, with 95.6% occurring within 0-12 hours and lasting 0-2 days.

The study faced significant challenges in recruitment and data collection, highlighting the need for improved methods in future larger trials, but it confirmed that no serious adverse events were reported during the treatment.

In a study of 202 patients with cervical radiculopathy undergoing surgery, no significant differences were found between structured postoperative physiotherapy and standard care at the 6-month follow-up, although all patients showed improvement from baseline.

Patients who attended at least 50% of the structured physiotherapy sessions experienced greater improvements in pain coping strategies, suggesting that while both approaches are effective, higher engagement in physiotherapy may enhance recovery outcomes.

There is low-level evidence suggesting that cervical manipulation and mobilization can effectively reduce pain and improve range of motion in patients with cervical radiculopathy, but these interventions were primarily studied in single randomized clinical trials.

A combination of spinal mobilization and motor control exercises may be more effective for reducing pain and activity limitations compared to separate treatments or a wait-and-see approach, indicating that multimodal strategies could be beneficial for these patients.

A systematic review of 59 trials involving 4108 participants found very-low certainty evidence that conservative treatments like acupuncture, prednisolone, and cervical manipulation may provide short-term relief for pain and disability in adults with cervical radiculopathy.

The review highlighted a significant lack of high-quality evidence for the effectiveness of conservative interventions compared to surgery, indicating a need for further research to better understand treatment options for cervical radiculopathy.

Cervical manipulation and mobilization techniques for neck pain are generally effective but can be associated with rare serious adverse events, as highlighted by a review of studies from 1998 to 2009.

The review found that while 17 out of 76 studies reported no major adverse events, minor adverse events like transient neurological symptoms and increased neck pain were noted, indicating a need for better reporting of adverse events in manual therapy research.
